Nelson was sufficiently advanced with the development of his
battery cartridge refueling system and the design of a demonstration racing
design to file a patent application in the winter of
1990. The above letter from the Patent Office confirms receipt of Nelson's
application and the date of filing as 21 November 1990.
The obvious way to promote
the performance of cars using his patent applied for, refueling system was to
follow in the footsteps of Henry Ford, who also thought to set a land speed
record on a frozen lake to draw attention to the performance of his
cars.
Nelson had already
constructed a prototype vehicle to demonstrate his patent mechanical joystick
control which replaced the usual floor pedals and steering wheel (patent GB2218187)
This car, built around his joystick control was named the 'Borzoi' after the
Russian hunting dogs famed for their grace and speed. The 'Borzoi"
was no slouch, topping 175mph in some tests using a 2.8 litre injected V6 petrol
engine.
A patent was finally granted
to Nelson for the battery cartridge refueling system in April of 1995 under
patent number: GB2253379.html
This
patent has now lapsed under the rule that many inventors view as unreasonable,
that patents only have a 20 year shelf life. The 20 year time frame is simply
not realistic where some technologies are more than that ahead of their time, so
will not have any commercial value until the patent has lapsed.
Thus the act of filing a patent is in effect giving away information for free.
If
you are an inventor you may wish to consider this and not file, for the
protection you are seeking, the state will deprive you of under the present
system. The system needs to be changed to take into account that patents
should only start running from when they are first commercially exploited
- not from when they are first filed.

DESCRIPTION
I, NELSON JAMES KRUSCHANDL, Inventor, of "Oakwood", Lime Park, Church
Road, Herstmonceux, East Sussex, in Great Britain, do hereby declare the
inventions, for which I pray that a patent may be granted to me, and the methods
by which they are to be performed, to be particularly described in and by the
following description This patent document may be seen as unusual inasmuch as it
contains and brings together a number of separately patentable new inventions,
which may be used on their own, or in combination with one another, or in
combination with any known method of electrically propelling a motor road
vehicle.
However, it is the considered viewpoint of the inventor that each of the
separate new innovations described in this patent description and the claims
following, are associated in such a way as to be bound together by an overriding
unity in a Comprehensive Electric Motor Road Vehicle System, (to be known
henceforth as the "Wolverine" system) if the system is to be described
and enacted in the most useful form/combination(s).This fact in no way
diminishes or restricts the uses or applications to which those separable
inventions may be put to in the future, and the disclosure by the inventor in
this patent specification and this application should in no way restrict and is
not in any way shape or form to be taken as restrictive, so far as each separate
stage/step of the intellectual development of this present system may be used in
the development of electrically powered transport systems, lest the inventor be,
in effect, penalised by the state and the patent system for his efforts to make
public his progress, as clearly this is the very reason the patent system has
been evolved. The disclosure of these inventions is made with the intention that
in so doing, he will pass on the benefit of his progress to his fellow man and
be rewarded through normal lawful commercial enterprise.
These inventions relate to an electrical drive motor, electrical drive motor
cooling system, brake/regenerative-brake application and control and/or power
supply/collection and/or power generation arrangement/system and/or a multi-fuel
fuel conversion capability and/or a vending system for electrically powered
motor road vehicles for use on the public highways as transportation and for
transportation where: - a) The drive motor and/or regenerative braking system is
constructed as part of (incorporated into) the wheel/hub/axle/brake assembly as
an integral part of the wheel/hub/axle, to form a wheel/hub/axle-motor and
brake.
b) The wheel/hub/axle-motor and brake assembly or wheel-motor, is cooled by
natural airflow over an open motor design; or is cooled by fan assisted airflow
through a ducted motor design; or is cooled by heat transfer from the motor
components and especially the windings via a heat-conductive paste to a

finned
radiator/heat-sink; or is cooled by circulation of a heat-conducting liquid
medium over or through the wheel-motor components.
c) The method of providing power for the electrically powered vehicle is aided
by a direct percentage contribution from high efficiency solar power panels
converting light to electrical energy while the vehicle is driven, and a
percentage contribution which is stored in e) below, when the vehicle is
stationary or parked (assuming adequate sunlight conditions in both instances).
These solar cells or photovoltaic effect cells can be of the Gallium-arsenide,
Cadmium, Silicon, or any other known combination of elements or compounds
converting light to electrical energy.
d) The method of providing power for the electrically powered vehicle is aided
by a regenerative braking system, providing electrical energy which is stored in
e) below, as a contribution or percentage of the total drive power requirement,
where/when the main drive motors are switched electrically and/or electronically
to a generating/charging mode progressively or in stages, according to brake
lever loadings/driver inputs and returned to drive motor mode as demanded by
accelerator loadings/driver inputs. Said generated electrical energy being
suitably transformed/electrically/electronically upgraded to a value suitable
for charging, hence storage in the vehicles 5 power-pack storage battery.
e) The method of providing power for the electrically powered vehicle is by
drawing on stored electrical energy from electroreversible cells/batteries of
the lead-acid, nickel-cadmium, sodium-sulphur or any other type/combination of
secondary cell chemically storing electrical energy. These storage cells being
charged by any known method of charging batteries and especially by c) and d)
above and h), i), and o) below and the battery bank also serving as a buffer in
the system for contribution charging purposes.
f) The method of providing power for the electrically powered vehicle is from a
conversion of gasses/liquids/liquid gasses, or dissolved gasses and/or liquid
solutions, to electrical energy in a refuellable primary cell or battery of
cells or fuel cells, as accompaniment to c), d) and e) above, or as the sole
power generator/supply, the system being particularly applied as a small
self-contained unit to form a compact generator, the compact generator charging
the onboard power-pack(s) to form a hybrid vehicle variant with an alternative
fuel source to that normally associated with hybrid (i.e. a petrol-electric
vehicle) electric vehicles. The compact generator also being designed for use
with the gas fuel of hydrogen contained in the storage medium, as explained in
g) below.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 3
PATENT DESCRIPTION CONTINUED
g)
The method of storing hydrogen gas for use in a gas fuelled form of fuel
(primary) cell in f) above is in the form of a hydride in combination with metal
alloys in the form of: pellets, their construction or make up being; porous
spongy metal plates; an open celled microcellular slab/block; a
wire-wool-stranded mass, all of these metallic forms designed so as to increase
the surface area available for reaction with the hydrogen gas. The reactive
metal form being encapsulated by or contained in a sealed pressure vessel so as
to form a gas or fuel tank from which gas may be drawn when warmed/liberated and
fed into the fuel cell reaction chamber.
The method of providing power for extended range use is by using an onboard
dynamo/alternator coupled to a small internal combustion engine of the
reciprocating (petrol, diesel) or turbine variety, or an external combustion
engine of the Stirling engine type (R. Stirling 1816 pat. no. 4,081) to form a
compact generator. The compact generator charging the onboard battery power
pack(s) in e) above, to form an electric vehicle commonly referred to as a
hybrid.
i) The method of providing power for extended range usage is by arranging for
the electroreversible storage battery of cells in e) above to be exchangeable by
a quick release/loading/unloading mechanism/system so that said battery power-pack(s)
that have been exhausted of charge may be exchanged with/for fully charged
battery power-pack(s) which also fit dimensionally, use the same loading
mechanism and offer similar performance and capacity as a standardised
specification battery pack or packs or as a battery store power-pack
specifically intended for use by the vehicle so equipped. These standardised/replacement
battery store power-packs or specially designed replacement battery store
power-packs being made available at roadside vending/charging/service
stations.The standardised or specialised battery store power-packs optionally
being replaced with a spare pack normally kept and charged at a home base.
j) The method of regulating and controlling power application to the drive motor
is by electrical and/or electronic solid-state:
switching/pulsing/chopping/amplifying and/or variation/modulation/wave
generating/devices circuits, units, systems, means.
k) The method of providing variable tracking or differential effect (where
required), is by proportional speeding up, or slowing down, of left or right
tracks by taking instructions from the physical position of the steering
controls via a sensor/transducer and a direct link with the vehicle speed
controllers, and/or alternatively is by an indirect microprocessor/computer
electronically controlled motor-wheel speed
correction/synchronization/orchestration, and from steering control sensor
variation/inputs/demands, and/or

alternatively
is by interactive self regulating and compensating circuitry designed to prevent
excessive unloaded speeding of any drive motor and further designed to even out
the distribution of driver-demanded power between the number of drive motors on
an axle.The system also acting as an anti-lock brake skid preventing device.
1) An alternative method of commutation is by using electronic switching of
current to the armature windings, back e.m.f. and driver inputs providing
essential control inputs to high speed microchip processor(s), enabling high
performance applications.
When permanent magnets or self-exciting windings are used as the field, attached
in the wheel rim in lower power applications, this method would eliminate carbon
brushes from the wheel motor altogether. If powered field windings are required
as, for example, in higher output or longer life applications, only slip rings
will be required for supply.
m) The method of providing power for the electrically powered vehicle is a
combination of a, b, c, d, e, f, g, h, i, j, k, 1, n, or o, in any order,
quantity or association and/or any other known method of providing or applying
electrical motive power to form a practical, comprehensive electric
motor-land/road-vehicle system.
n) A method of keeping constructional complications to a minimum and further
reducing vehicle weight is by incorporating the battery pack storage, location
and quick release/pick-up system into or as part of the chassis' main structural
members/components.
o) A method of providing a vehicle with a multi-fuel capability, that is to say
the ability to use more than one type of fuel as the source of motive power is
by adopting a dimensionally standard loading, securing mechanism with electrical
connections also in a dimensionally standard and fixed position in relation to
the securing mechanism, so that any form of generator and/or electrical store so
designed to comply and be compatible with the dimensional requirements, may be
loaded/connected into/onto/with the vehicle power supply circuitry and controls.
HISTORY
The development of an efficient electrically driven motor vehicle has been
overshadowed during the past century by progressive improvements to vehicles
powered by internal combustion engines. The reasons for this are manifold:
ONE - The necessary technology had not, up until now, been available to make an
electrically powered vehicle which could compete with its internal combustion
rivals on range, performance and practicality.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 5
PATENT DESCRIPTION CONTINUED
As long ago as 1897 Ferdinand Porsche, then under the employ of Ludwig Lohner,
was presented with the opportunity to design and build a battery powered car
using hub-mounted electric motors. Unfortunately, the range of 32 miles at 9 MPH
limited applications of the vehicle known as the "Lohner-Porsche
Chaise". Later, in 1901, Porsche developed this theme further by replacing
the heavy and cumbersome batteries with a generator unit powered by a Daimler
petrol engine. He still used electric motors incorporated in the front wheel
hubs and this vehicle known as the 1901 "Lohner-Porsche" achieved a
maximum speed of 55 MPH. The 1901 "Lohner-Porsche" was probably the
first petrol-electric hybrid in history.
In Great Britain, the Luton firm of E.W. Hart built their "Toujours
Contente" and "Presque Contente" models featuring a Lohner-Porsche
motor in each hub making them, in all probability, the first four-wheel drive
cars. In 1907, Mercedes joined in the race to develop an electric car.
Porsche was commissioned by them to design their "Mercedes-Mixte"
model, which was a petrol-electric hybrid.
By any standards the performance attained by these electric vehicles was, at the
time, astonishing. The world land speed record, held by Jenatzy 1899., was only
65.79 miles per hour rising to 121.57 MPH in 1906 when the steam powered Stanley
Rocket stole the lead. If Porsche had had the knowledge of electronics, solar
collectors, steel wheel construction and modern batteries, most of us would now
probably be driving around in electrically propelled cars and the internal
combustion powered vehicles we take for granted, would have only commercial and
perhaps sporting applications. Proof of this statement can be seen in the
absence of internal combustion engines in any modern permanent industrial
installation. In other words, if electrical power can be made practically
available in a given application it is almost always used in preference to other
energy sources.One reason for this is the efficiency with which electric
machines convert electric power into useful motive power. Commercial generating
installations often achieve efficiencies of 98%.
Other factors such as convenience, quietness and cleanliness must also be taken
into consideration.
Whilst 1,575 electric vehicles were manufactured in 1900 in the United States
compared with only 939 gasoline powered vehicles, the trend was soon to reverse.
Electric vehicles were very popular with women because of the difficulties of
starting an internal combustion engine with a manual crank.
Then in 1911 the electric self-starter was introduced by Cadillac. Soon other
manufacturers incorporated the self-starter onto their piston engined vehicles
and that particular problem was solved opening the way for practical everyday
use of I.C.E. powered automobiles by the fair sex.
B60
K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 6
PATENT DESCRIPTION CONTINUED
After 1930 production of most electric vehicles had stopped, being regarded
largely as museum pieces. One exception was the "Detroit Electric",
built by the American Anderson
Electric Car Co., which continued to be produced to special order until 1939.
More recently, and as a direct result of soaring petrol prices and the very real
possibility of petrol rationing in the 70s, experimental studies have led to
promising EVs being built and tested by, for example, the Electricity Council
who evaluated the "Enfield" vehicle in 1973 - 1976. The idea was to
use the vehicle for meter-reading duties.
The Electric Power Research Institute (Palo Alto) suggested that a modern day
electric vehicle represents a major new revenue source for electric utilities.
It has been estimated by them that each vehicle would use the equivalent energy
equal to or exceeding that used annually by the average household. This would
help solve the problem of power station load management as charging of EVs from
domestic supplies would normally be carried out overnight from off-peak
supplies.
This practice could mean power stations were able to operate more efficiently
and would not necessarily require -any expansion to cope with demand. General
Motors are at this time running fleets of essentially overnight charged vehicles
("G" Wagons), in selected city areas for just such evaluation.
Power taken directly from nature as the conversion of sunlight has also been
investigated but without any practical form of application. Vehicles running on
sunlight only cannot be used all the year round because of unpredictable
fluctuations in the weather and presumably the application of "Murphy's
Law".
Nevertheless, research has continued apace with vehicles mainly intended as
competitors in the Pentax World Solar Challenge, a race across Australia, north
to south, from Darwin to Adelaide, a distance of 1,875 miles. Vehicles competing
in this race can only be described as thoroughbred out and out racing machines
with little or no practical application. For example GMs "Sunraycer"
and the Solar Honda are both pure teardrop aerodynamic exercises arranged around
the forward seated driver with a massive flattened tail to accommodate a very
large solar panel collection area.
However, these developments have proved that electricity from the sun is a very
real energy source just waiting to be tapped.
There are two main problems associated with the purchase and running of
electrically powered vehicles planned for launch by mainstream manufacturers in
the near future. Firstly, state of the art battery developments still allow
ranges of only 60 - 150 miles. This limits the market for electric vehicles to
those who only use cars for short distances/round trips.
The assumption being that a vehicle will return to a home base where it can be
trickle-charged from a domestic electricity supply. Commuters and families
wanting to travel longer
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 7
PATENT DESCRIPTION CONTINUED
distances
are not catered for. This is clearly a problem and limits the electrical vehicle
as a practical proposition.
Secondly, the replacement price of a new battery pack after approximately three
- four years use (20,000 - 40,000 miles), has to be taken into the calculations
of total fuelling costs.
This fact detracts from the obvious financial advantages of using a renewable
fuel source and is seen to be an obstacle to the economical running of an E.V.
TWO - There has not, before now, been the urgent need for an alternatively
fuelled method of transport. In the early days of motor vehicle development oil
derived fuels were plentiful, as nobody had then found a volume use for the
refined petroleum spirit. It was because of the growing popularity and
practicality of the internal combustion engine that a market for the otherwise,
unused by-product, was created. The abundant distribution of petroleum deposits
in the Earths sub-strata and competition from oil producing countries has kept
petrol supplies reasonably priced. Indeed petrol/oil fuels have been taken for
granted as a cheap source of energy by most industrial nations and is the device
by which economies are kept buoyant. Thoughts of this fuel supply running out
seem to have been conveniently filed for later attention.
Exploration for petroleum oil deposits continues expeditiously in order to
replace existing wells that are being drained and as a result the price of
petrol for transportation is bound to rise. So far, however, any increase has
not been sufficiently large to discourage the world's motorists from wasteful
journeys and any increases imposed, certainly have never, in real terms,
reflected any harmful effects to the planet Earth and/or the cost of
cleaning-up, or righting, pollution from oil spills, etc.
Supplies of oil for refining to petroleum are subject to political and other
market forces which can seriously damage any governments's attempts at economic
planning and stability for their country. In recent times pressure for the
continued supply of cheap oil, to meet many countries energy requirements, has
caused a situation of international concern in the Middle East. This area can
accurately be described at this time as the oil well of the world. Any reduction
of dependency on this resource would be a good thing.
In any event, oil is a non-renewable fossil reserve which is due to run out in
the near future. There is, therefore, a pressing and long overdue need for the
development of an alternative to the internal combustion engine.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 8
PATENT DESCRIPTION CONTINUED
THREE - It has only recently become recognised that emissions from the
combustion process could be permanently harmful to world ecology. The burning of
hydrocarbon fuels has been associated with extensive world-wide carbon
dioxide/monoxide pollution which has been linked with a condition of global
warming. Global warming, it is argued, could have dire consequences for the
future of the planet Earth and if allowed to continue at its present rate may
re-draw the hospitable borders on maps of the future. The internal combustion
engine is a major contributor to this pollution, producing about 20% of the
greenhouse effect Carbon Dioxide gas, 75% of the poisonous Carbon Monoxide and
50% of the smog forming Hydrocarbons.
In allowing this situation to continue unquestioned, we'are de facto accepting
the inevitability of damage to our environment, as the price necessary to be
paid for our present and continuing motoring pleasure.
Urban smog caused by fumes from the I.C. engined car has now become such a
problem in hot climates that they pose a serious health hazard. Huge yellow
clouds hang over Los Angeles on bright days formed by the action of sunlight on
Nitrogen Oxides and Hydrocarbons, to form Ozone. Parents quite rightly keep
children in on hot days to prevent inhalation of the carcinogenic fumes which
give rise to all manner of breathing disorders. This has promted bodies such as
the "Clean Air Resources Board" and "South Coast Air Quality
Management" in the state of California, U.S.A. to help introduce
legislation designed to induce car makers locally and exporters worldwide to
manufacture and offer to the public the option of a clean automobile. It must be
remembered that worldwide production of vehicles runs to around 130,000 units
per day.
Los Angeles is particularly a problem area having a population of some
12,000,000 people driving 8,000,000 vehicles. Probably the highest concentration
of vehicles per square mile or per person in the world. Accordingly, this would
seem a logical place to start corrective measures and may prove to be a much
needed model for the rest of the world to follow. At this time it is recognised
that electricity offers the only real solution to clean motoring.
For the above reasons, a system of environmentally harmonious transportation
(preferably using renewable energy) is quite clearly a desirable proposition
both commercially and ecologically.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 9
PATENT DESCRIPTION CONTINUED
To date, sporadic efforts have been made towards developing alternative forms of
transport, mainly by forward thinking research organisations, with a
"green" rather than commercial bias. This has led to experimental
battery powered vans and cars which require overnight charging from "off
peak" mains electricity supplies as their only source of power input.
The race so far has been confined to seeing who could squeeze in the biggest
battery pack; this seemingly being the only solution to extending ranges and
improving speeds although research into batteries of cells with higher charge
densities is helping to reduce the size and weight of those battery packs. The
making of power in electricity generating stations, gives us the easier option
of centralised pollutant removal/treatment as an interim solution, during the
long-term phasing out of old technology.
Some manufacturers have chosen to experiment with alternative renewable fuels
that can be used in the internal combustion engine, thus capitalising on the
large numbers of vehicles in existence using that system as the prime mover.
Recent examples of these alternatives are: Alcohol, Methanol, Propane, Methane
and Hydrogen, although there are many others. The case for hydrogen is, on the
surface, extremely good. Closer analysis of the conversion chain reveals marked
inefficiencies of the system that manufacturers seem prepared to overlook,
because hydrogen vehicles can be refuelled in about 15 minutes safely using the
hydride pellet storage method if pumped cooling water is used (see Mercedes 310
minibus).
Water is split into hydrogen and oxygen using electricity by electrolysis
(hydrogen derived from fossil fuels being very expensive and counter
productive). The liberated hydrogen gas is then attached to the metallic sponge
pellets (catalyst) in the vehicle's fuel tanks, forming a hydride.
The gas is released from the hydride state by the application of heat from the
I.C. engines exhaust pipe. Then the original weakness in the chain becomes
apparent, as any internal combustion powered land vehicle can only effectively
deliver a miserly 20% of the original fuel energy supplied to it. By contrast,
electrically powered land vehicles regularly achieve 70% efficiencies through
their drive trains.
The only real drawback being the time taken to refuel/charge the batteries of a
conventional electric vehicle - normally 8 to 10 hours.
It is becoming universally realised that fossil fuel reserves ought to be
safeguarded for more important tasks where renewable energy sources cannot be
used at this time (i.e. travel by flight), or as insurance against a future
situation which may prevent us using naturally abundant renewable resources.

PATENT DESCRIPTION CONTINUED
IDENTIFIED PROBLEMS
There is no fully integrated or comprehensive electrically powered vehicle
system suitable as a replacement to traditional methods of transport. The
systems being developed by manufacturers of motor vehicles at this time are half
way, add-on, conversions using existing production vehicle technology, which in
no way makes the best use of newly developed advances in technology in a
format/system specifically designed from the ground up as a comprehensive
electrically powered vehicle system/package. This approach is reflected in the
poor performance figures quoted by manufacturers for their first batch of Los
Angeles qualifying vehicles.
The main weaknesses in the design of electrically powered vehicles to date are
the restriction on range and performance; the result of long refuelling times,
without any method or provision for refuelling along the public highways. If the
refuelling problem can be overcome, then higher performance will follow and
electrically powered vehicles may then offer practical long range motoring.
The other critical area of design and application for attention is the way
electrical power from motor machines is brought to the vehicles tyres; that is
the efficiency of the drive system.
INNOVATIONS
These present inventions replace and/or incorporate known methods of electrical
motivation, energy storage and vending with:- recent technological advances in
solar cell, fuel cell, electrochemical storage cells; and/or a new
motor/wheel/hub/axle arrangement and control incorporating the latest advances
in electric machine/motor design and electronic power control or handling;
and/or a new battery-power-pack loading and unloading or refuelling system;
and/or a new add-on multi-fuel capability; and/or a new battery-power-pack
vending system; and/or a new solar cell deployment, to form a workable and
practical electrically powered motor road vehicle and energy supply system,
which can either supplement or replace altogether the internal combustion engine
powered motor road vehicle.

METHOD OF INTEGRATION AND APPLICATION
COMBINED WHEEL, HUB, AXLE, BRAKE AND MOTOR DRIVE:
The electrical motor design/make-up of this present Wolverine system, which may
include the following components depending upon motor type, A.C., D.C. or
hybrid: windings, cores, armature, stator, rotor, commutator, slip-rings,
permanent magnets, cages, spiders, brush assemblies, filters, guards and
regenerative braking parts, cooling fans, cooling sinks, cooling jacket(s) and
any other component normally found/needed in an electric motor machine, are
incorporated in'the wheel rim, hub and axle that would normally be found on a
conventional vehicle set-up (live or independent axles).
This has the advantages of :1) SAVING WEIGHT - by sharing and combining the uses
of basic component parts found in a normal wheel/hub/axle assembly with the
motorising electrical components needed to complete the assembly so becoming a
motor-wheel/hub/axle or motor-wheel.
For example: - The stub shaft shares the commonality of function with the motor
spindle or shaft; The wheel rim shares the commonality of function with the
motor casing or yoke; The wheel spokes/central pressing/casting, shares the
commonality of function with the motor spider and in some cases, casing; The
wheel bearings share the commonality of function with the motor bearings. By
this means (method of incorporation), motorising components may be added to a
wheel hub assembly adding only 0.5 - 51bs per horsepower output (0.3 - 3kgs per
kilowatt) or less, depending on the technology applied, to make a light
motorised wheel or wheel-motor.
A standard vehicle (small sedan deployment example) requiring a total of 20kw
(26.8HP) output, would require 4 X 5kw wheel motors (all wheel drive) or 2 X
10kw wheel motors (front or rear wheel drive only), assuming a vehicle with four
wheels.
Any particular arrangement of drive motor-wheel layout may be decided by
production capacity, cost, performance or indeed a multiplicity of applied
criteria.
DIRECT CURRENT MOTOR EXAMPLE WITH MECHANICAL COMMUTATOR
To maximise weight savings and eliminate the need for two sets of brushes in a
conventional direct current application, i.e.
to supply field and armature windings, it is desirable to use a ring armature
fitted in the wheel rim/motor-casing/yoke, to revolve around an arrangement of
field windings (with two, three, four, five, six, seven, eight, nine, ten, or
multiples and/or additions of these numbers of poles according to desired motor
characteristics) being fixed or located (by splines, pins, pegs, threads, keys
or similar) with or without a connecting metal spider, in such a way as to
prevent rotation on the stub axle/motor shaft, being a reversal of the way an

motor forming the hub of a wheel). A hollow spindle/stub axle can then bring
current carrying cables to either an outward facing commutator brush arrangement
or to the central field windings, depending upon the particular wheel
arrangement (see diagrams of design examples).
It will be seen to be advantageous to bring the end wires from the armature
coils towards the centre along the spider/spokes/casing/central pressing of the
wheel, to give physical support to the wires, then towards a smaller diameter
commutator/collector where the wires will terminate in the normal manner by
being pressed into a slot and then soldered in position. The commutator brush
pick-up assembly is arranged in such a way that it can be taken away from the
commutator with or without the wheel and be self relocating.
That is to say, by virtue of radiused edges and a lead in portion of the
commutator collectors (usually copper) or before the commutator collectors, the
brushes retract into their respective guide slots, preventing the normal jamming
caused by sharp changes in profile and aiding assembly.
An alternative design has the brushes coming from inside and making contact
against the inside face of a commutator whose collecting metal segments are
fitted on the inside of a supporting ring, instead of on the outside as is more
usual.
This has the advantage that for tyre servicing purposes the wheel/armature/commutator
assembly may be taken from the hub, stator and brush pick-up assembly without
having to disconnect the brushes from the electric supply cables.
Direct current brushed machines are considered by some electrical engineers to
be out of date and potentially less efficient in converting electrical energy
into mechanical energy. But there are many advantages to this type of machine
stemming from the simplicity of construction, repairability and low-tech control
requirements. For example, isolated communities, without sophisticated
electronic test/service equipment will be able to effect all servicing
requirements that would be almost impossible with the software driven brushless
machines described below. Similar long term servicing problems of petrol engined
cars equipped with electronic engine management systems are now working their
way through the second hand car market, with those electronically equipped
vehicles drastically dropping in value and prematurely ending up on the scrap
heaps. This is of itself of some environmental concern.

PATENT DESCRIPTION CONTINUED
BRUSHLESS DIRECT CURRENT MOTOR ADVANTAGES
Mechanical commutator switching limits the electromechanical power conversion
potential of the d.c. machine. Centrifugal force considerations and the need to
clamp onto securely, limit the diameter, rotational speed and length of the
commutator, although rotational speeds of 1,000 - 2,500 RPM for wheel diameters
of 16 - 30 inches may not present too much of a problem. The desire to limit the
thickness of insulation between adjacent commutator segments also introduces
design restrictions.
Many of the limitations are mitigated if electronic commutation of the armature
coils is applied. One immediate advantage is that the armature winding may then
be accommodated on the stator, in this case being secured to the
stub-axle/bearing spindle, with consequent easing of the problems relating to
insulating and securing the conductors.
The apparent need for slip-rings and brush-gear associated with supplying d.c.
exciting current to rotating main-field coils may be avoided by mounting a/the
exciting-generator or exciter on the common shaft. Thus, if commutation is
achievable without the need for interpoles, a very simple rotor assembly is
possible. On some wheel-motor applications permanent-magnet field poles may be
employed, also solving the problem. Using the latest rare-earth magnetic
compounds very powerful yet lightweight wheel-motors may be constructed.
Electronic commutation eliminates the chance of an arcing brush/commutator
contact. Assuming that the controlling semiconductor devices are able to meet
the switching duty requirements, overall dimensions are eased and
retarding/advancing of the commutator timing to improve the motors flexibility
may also be enacted through the same controlling/switching electronics via
software. Coil short-circuiting during commutation may also be eliminated using
electronic commutation and the number of armature coils normally needed to
reduce this short-circuiting to insignificance, may also be reduced to simplify
manufacturing and design complications.
ALTERNATING CURRENT OR SYNCHRONOUS MOTOR ADVANTAGES
The drive motors may be of the alternating current type, this design of motor
being theoretically potentially more efficient in the conversion of electrical
energy into motive force. A.C.
motors also promise greater longevity of service, as no commutator or slip rings
are required not only reducing complexity but also frictional losses. Speed
regulation and power application in this type of motor requires sophisticated
electronic circuitry, firstly to generate an alternating supply/wave from the
vehicle D.C. batteries and then to regulate that supply by frequency and/or
pulse modulation.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 14
PATENT DESCRIPTION CONTINUED
It may be argued that the D.C. brushless machine and the A.C. machine described
above stray into each other's territory as both are in effect motors without
brushes operating from software generated waveforms and this is true. The
difference lies in the construction of the machine. For example, whether
permanent magnets or induced effect are utilised.
The motor wheel is of course designed with the facility of speedy servicing of
wheel bearings, brushes (where used), brakes and tyres. It can be seen from
examination of the accompanying drawings that none of the normal wheel and hub
servicing requirements are unduly affected. It must be recognised that the
system remains advantageous and workable no matter what design/type of electric
motor machine is employed in this capacity. Although it may be shown that some
designs and types demonstrate greater suitability to the application than
others.
It must be emphasised that this present wheel-motor invention relates to the
concept of incorporating an electric motor machine within the structure of a
modern road wheel/hub/axle assembly and in no way restricts the invention to any
particular type or design of electric rotating machine, but by giving example
and description of certain types, in particular the D.C. machine by way of the
suitability of D.C.
machines to tractive (motor vehicle) applications, endeavours to make it readily
apparent to the reader the basic requirements of/for the system to work
effectively.
2) DIRECT DRIVE - routing/transmitting power by shafts from a single motor is
eliminated and reduction by gears can be cut out of the drive train because of
inherent electrical wheel-motor torque characteristics, so improving efficiency
and saving more weight. Drive may be distributed to two or four wheels simply by
having motor units built into the desired number of wheels. If motor speed down
gearing is necessary in a particular (heavy duty truck) application, hub or
wheel rim reduction by an epicyclic arrangement would still enjoy a considerable
efficiency advantage.
3) FEWER MOVING PARTS - with electronic solid state switching and speed control
of the motor only the tyres, shock-absorbers, wheel bearings and commutator
brushes (if used) suffer from frictional wear (plus gears if incorporating heavy
duty hub/rim reduction). Brake pads and/or shoes would be the only other
mechanical item requiring service and as this is also part of the wheel/axle
assembly, maintenance of the vehicle, taken as a whole, can be seen to be
minimal.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 15
PATENT DESCRIPTION CONTINUED
4)
HIGH TORQUE - being improved with large radius field and armature windings,
making the most of the available wheel rim space. Additionally, the torque and
drive power of each motor/wheel is multiplied by the number of driven or
motor-wheels to give the total vehicle drive power and start off torque. In this
way four driven wheel units would be the equivalent of a very large and heavy
single electric motor, with the advantages that a number of smaller units have
an increased surface area giving superior cooling characteristics to the machine
for extended longevity and performance, apart from any torque considerations.
The winding insulation life-span may be extended beyond 50,000 hours as a result
of cumulative advantages and heat sink or liquid cooling techniques.
5) TWO MOTORS IN ONE - the adjustable commutator brush/pick-up unit/assembly
allows greater flexibility to be obtained from any fixed winding configuration,
by adjusting the commutator timing, effectively tuning the motor to a speed or
torque requirement and extending the flexibility that would otherwise be
impossible using power control alone.
6) NO DIFFERENTIAL - is necessary with any of the drive arrangements described
in normal operating conditions, further simplifying the system. Each motor
tending to adjust itself within acceptable limits to the rotation speeds of the
other motor(s) for cornering purposes.
If by reason of slippery conditions or loose surfaces, differential effect, or
tracking control and monitoring is required, a central microprocessor/computer
controlled, multi-channel speed controller can individually regulate and
synchronise each separate motor wheel for any particular cornering condition, to
optimise grip. To make this work, each motor wheel unit would feed information
from inbuilt transducers of load information and r.p.m., to the central control
computer/microprocessor. The information received would be compared with what
should be happening according to reference information and corrected as required
to maintain a stable course. Separate (matched) speed controllers (as channels)
will be required for each motor wheel, but it may well be that these separate
speed controllers are, by virtue of more readily available component values,
just as economical to employ than one large speed controlling circuit.
A different system of self-regulation can be used as a cheaper alternative,
possibly being slightly less effective in use as a differential system than the
microprocessor controlled system described above and by contrast a direct acting
cross linked analogue electrical control circuit, where one wheel motor takes
overriding percentage adjustment instructions of power application requirements
from the opposing axle wheel-motor, via what is essentially a balanced
apportioning system. Apart from any cost consideration this is the system that
is likely to be adopted for the mass market because it
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM.Page 16
PATENT DESCRIPTION CONTINUED is an easier system to implement and is likely to
be more reliable in service as it is possible to arrange the electronics to use
only one split channel or two lower output channels to give the same end result.
Each motor-wheel has its own speed controller. The speed controllers are
initially instructed in parallel equally by the driver operated speed control.
If one wheel speeds up in relation to its opposite axle wheel-motor, the current
drawn by that unloaded wheel decreases. A rotation speed sensing and regulating
circuit keeps each separate motor in % synchronisation with its opposite axle
motor, provided there is no change in load of one of the motors. If both motors
change loadings at the same time, as when cornering, sensors on each power
supply line detect which is drawing more and which is drawing less and provided
the changes balance each other within certain limits and the total flow remains
essentially equal as when driving the vehicle straight, then each motor will be
regulated according to the newly apportioned rotation speed.This has the effect
of providing an anti-skidding/overspin device that will keep the vehicle steady
on the course steered. The two separate power apportioning channels (one per
motor) may be considered/likened to a single axle-channel and divider/balancer/synchroniser
as it is posible to implement a single channel speed controller which provides
the same effect.
POWER SUPPLY ARRANGEMENT:
SOLAR CELL GENERATION
This present Wolverine system provides for collection of energy from nature in
the form of light converting photovoltaic cells or solar cells in the following
manner:
Solar cells are placed on the vehicle surfaces in such a way as to maximise area
and attitude for collection, without interfering with driver sight line or
vehicle functional components. Typically, five to ten percent (5 - 10%) of the
normal/average running requirement can be supplied directly in this way,
requiring three square metres or more of solar cells.
The solar cells charge an onboard electrochemically reversible cell/battery when
the vehicle is not in use (assuming an average for sunlight conditions). The
solar cells also contribute directly to power requirements when the vehicle is
driven.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 17
PATENT DESCRIPTION CONTINUED
When light levels fall below a level where the voltage output of the solar
collector components no longer provide any significant input, a circuit inserted
into/onto the system for regulation/disconnection purposes breaks electrical
contact.
This may be determined by a cadmium sulphide or similar light sensitive
resistive grid or other electronic component forming a sensor/transducer, one
way switching by diodes, or voltage drop regulated relays. Essentially, this
automatic electronic/electrical protection takes over, preventing discharge of
the power batteries and damage to the working components. The solar cell panels
are also overload and temperature protected in the normal way.
The solar cell panels are incorporated as lightweight structural plastic
sandwiches into, or as, the body panels of the vehicle, so forming the body
panels of the vehicle.
Design of the shaped panels is kept as simple as possible while conforming with
the aerodynamic outline necessary for efficient air penetration by the vehicle
form.
It would be an advantage if the combined solar-cells/body-panels were easily
detachable for servicing/repair. Some panels on a motor vehicle may be easier to
remove than others. A fixed roof panel for example, has to serve as a weather
proofing medium and wind deflector in addition to energy collection duties.
Sealing of the mounting edges will be paramount to the public acceptance of such
a system - we have all grown accustomed to leak proof cars with smooth edges.
Thus a mounting system which prevents leaks and provides a sound structural
assembly is a must. This may be accomplished with a light plastic or metal frame
onto which the solar-body panels fit mechanically and connect electrically.The
mating surfaces/edges of the solar-body panel may screw or clip onto the frame,
but the important sealing feature is a returned edge in the frame which doubles
back under a fixed panel to form a channel which collects and funnels water away
from the mating surfaces, so acting as a built-in drainage system. Panels such
as doors, bonnet and boot do not of course require much modification. However,
it must be noted that commonplace everyday vehicles already have lips, channels,
gutters and drains built into the design of the vehicle for just such weather
proofing and that these edges often form the structural joins of a unitary
design. Recent trends have seen the removal of external edges, seams or lips in
the interests of good airflow management.
Conversion efficiencies of solar cells at this time vary between 8 - 16%
depending upon the type, materials used and construction. With solar isolation
of 1kW/Msq (bright sunlight) and isolation in Great Britain of only 125W/Msq
(averaged over 8760 hours/year) This equates to between 10 - 20 watts output per
square metre respectively.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 18
PATENT DESCRIPTION CONTINUED
Multiply an output efficiency of 8% X 3Msq X 8760 hours and an average energy
contribution per car per year = 30 watts X 3 X 8760 = 262.8 kW/hrs. Now divide
262.8 kW/hrs by 15 to gain the number of fully charged battery-packs @
120 mile range = 17.52 X 120 giving a total yearly (annual) contribution from
the sun of 2102.4 motoring miles (21%).
The battery store from a battery powered electric vehicle provides the perfect
temporary store to complement solar assistance and make the system work. A car
equipped as per this example will save fuel costs of 39.74 per year @
1.89 pence per mile (average) on an electric vehicle, or 126.14 per year
(average) on a petrol powered car equivalent (battery charge efficiency @
90% overall has not been worked into the above calculations).
The very latest developments in thin-film and plated manufacturing techniques
have led to lightweight high-power cells which when incorporated as purpose
built body-panels, in the sandwich construction described, need not weigh more
than just the body panel alone (requiring no rustproofing) in a conventional
steel bodied automobile. If that is the case, there will be no undue weight
penalty imposed by equipping a vehicle with solar-body panel collectors, only
the drawback of additional expense.
The cost of producing solar-body panels may be reduced using sealed acrylic
plastic (or other transparent plastic material) in place of high transmisivity
glass, the loss of transmission efficiency being more than made up for by the
reduction of cost per unit and associated manufacturing difficulty.
Costs of producing solar panels on the scale needed for automobile manufacture
may be cut by as much as 70%, especially with the new plated method of
manufacture. The reason solar panels are so costly at this time is literally
because of the specialist market. For example, calculators powered by high-power
solar panels may cost X pounds for a basic model. Earlier battery powered
calculators would have cost the same, but the cost of purchasing new batteries
would probably have cost half the price of the original item and will need
replacing again and again on a regular basis.
Because the solar panel has been included in the manufacturing process of the
calculator, the price of the solar panel included has dropped dramatically. The
problem is only one of scale.
Using this method of solar energy collection and control, energy can be supplied
by direct onboard sunlight conversion to annually cover 20 - 40% of an estimated
average mileage of 10,000 miles, i.e. the equivalent of 2,000 - 4,000 free
motoring miles every year. The remainder can be topped up by fixed/stationary
external collectors or mains electricity
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Pae 19
PATENT DESCRIPTION CONTINUED exchanges when the vehicle is at its home base, or
any overnight charging station. Spare packs can continuously charge at home and
in addition to collecting and charging from onboard vehicle and domestic
electricity supplies or roof mounted domestic collectors, power-packs can be
exchanged at a charging station.Additionally, either of the optional compact
generators described below will allow the use of another fuel type, adding
greatly to the versatility of the system.
ELECTROCHEMICALLY REVERSIBLE BATTERY OR POWER-PACK STORAGE
The power-pack battery bank or electrical store of this present Wolverine system
must be of sufficient size/capacity to give realistic vehicle ranges for
commuting and other medium range operation when weather conditions are
unfavourable and prevent useful contribution from the solar collectors. The
battery store and continuous output rating must also be adequate to sustain
motorway endurance over the distance. Realistic ranges will vary according to
intended vehicle use/application, but can be taken for the purpose of giving a
specific example as being between 50 and 300 miles.
This will require the very latest storage cells giving high density charge
ratios. Approximate figures have been calculated as being between 400 - 1,000
pounds in weight and 3 - 7.5 cubic feet in size, depending upon the
electrochemical properties of the battery cells being used and the applicable
vehicle format. These example specifications should provide between 8,000 and
45,000 usable watt/hours, again depending upon the type of storage cells being
used. Multiples of these specifications would need to be applied for heavier
duty or higher performance vehicles. Development work on storage cells may in
the near future upgrade power to weight ratios, especially the sodium sulphur
beta cell being developed by the Chloride Group.
Provision is made within this present Wolverine system for smaller separate
battery store(s) to be contained within the vehicle structure for the purpose of
supplying a reserve, auxiliary or emergency energy bank/store. The reserve
batteries are also to be used for powering/manoeuvering a/the vehicle at times
of servicing/loading/refuelling when the main power batteries have been
unloaded/disconnected.
Because of the requirement for a separate onboard store or reserve of electrical
energy, the reserve or auxiliary batteries are an essential part of the system
and will obviate the need for temporary external connection(s) or other
manouvering arrangements.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 20
PATENT DESCRIPTION CONTINUED
MAINS ELECTRICITY CHARGING
This present Wolverine system incorporates and caters/allows for overnight
charging from domestic mains electricity supplies to bring the accumulative
battery of cells up to full capacity from, maybe discount metered supply
companies.
Or on a solar assisted vehicle setup, when overcast weather conditions may
prevent solar charging or where longer range use has exhausted the vehicles
batteries and time shortage dictates the need for this extra input.
The mains charging facility is well known. Sophisticated charging equipment is
available giving printouts of charging information, warning of battery condition
and automaticoperation of tapered charging cycles specifically programmed for a
particular battery type. At least four vehicle manufacturers use the technology
on cars that are offered for sale to the public at this time. The reason these
cars are not more popular is that direct mains charging alone severely restricts
the uses to which the vehicle so tied may be put.
Mains charging is a slow process as the current state of the art persists,
taking between eight and twelve hours-in most cases to fully refuel/charge a
battery bank. The time-swop or time-management possible with an exchangeable
battery-power-pack, as described below, is what makes this present Wolverine
system a workable and practical system.
Time management is a concept that has been recently accepted on a world scale
via the technology of the videotape recorder equipped with a timer. A person may
take advantage of the videocassette tape storage medium to store recorded
broadcast material when he/she is not at home to watch the item, and by so doing
manage broadcasting times to suit his/herself. The principle is much the same as
taking electricity at a time of greater economy, to suit yourself and also
shifting charging timespans to suit yourself. In effect you will be storing
energy and time. Time is irreplaceable.
Enquiries of supply companies into the laws and conditions covering distribution
of electricity in Great Britain suggest that there is scope for independents to
supply there own electricity via the National Grid at about half the price of
the domestic supply rate, currently 7.35 pence per kw/hr unit, tax free.
Unfortunately, VAT or it's equivalent tax will almost certainly be added by an
enthusiastic Chancellor of the Exchequer on top of the Fossil Fuel Levy (11%)
already imposed on electricity generating companies and passed down the line.
Yet there is no pollution tax on petrol engined vehicles.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 21
PATENT DESCRIPTION CONTINUED
Despite any obvious political hinderances there remains a lot of scope for a
specialist pioneer supply company to A) offer value for money against the
present electricity supply networks B) open up new profitable markets where
traditional suppliers would not bother and C) further reduce the price of
electric motoring for the consumer.
In effect the battery-power-packs of the growing numbers of electric vehicles
will form a gigantic mobile energy store or load levelling device for power
generating stations - at no cost to those utilities. It has also been calculated
that by storing energy from overnight generated electricity power stations will
be able to operate more efficiently by making better use of their plant.
Additionally, because the bulk of this extra generated electricity is made off
peak, there should be no problems associated with overloading of the existing
grid network as has been argued. It is all a question of management.
INSTRUMENTATION AND BATTERY PROTECTION
Because of the investment in a battery power-pack it is necessary to maintain
that pack or packs in the best possible state of charge or operating condition
in order to prolong the working life-span or number of efficient charging
cycles. For example it is well known that even especially designed deep
discharge traction batteries should not be drained below a working threshhold
where cell damage will occur. It follows that in almost every storage cell type
certain conditions must be satisfied to protect the battery of cells.
Most vehicle operators will not be familiar with battery requirements and so at
least basic automatic warning or other protection should be provided/included.
It is essential that at least a visible or audible warning be given to a vehicle
operator, when the vehicle's batteries are in a poor condition.
A more comprehensive/versatile warning device would be a gauge or LED or
preferably also an LCD display with or without audible signal accompaniment
which would show stored charge and warn when overnight charging is necessary and
alert the user as to any other precautionary steps to take and/or confirm what
action is advised. The same information gathering and processing electrical and
electronic package may also form an information display instrument or gauge
doubling as a battery condition indicator and energy remaining or fuel-gauge,
when the vehicle is in use, and the information of remaining charge also used
for corrective/adjustment purposes in any power-pack(s)/financial exchange(s)
transaction(s). In this way vehicles parked with drained battery cells may be
avoided, and battery-pack exchanges regulated.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 22
PATENT DESCRIPTION CONTINUED
This present Wolverine system includes for such an instrument or warning
aparatus one example of which follows:
The instrument hardware forming the heart of the system is/are an electronic
kilowatt/hour measuring device and display and a battery charge/condition
measuring device and display, capable of working with normal vehicle voltages,
e.g. 50 - 500 volts plus or minus 10%. Both of which may form part of the
vehicles normally required instrumentation, although the displays should be
clearly distinguishable to avoid confusion. (These electronic/electrical
measuring devices and displays being the equivalent of a petrol tank fuel gauge
and fuel flow meter on a petrol fuelled internal combustion engine driven
vehicle).There should be a separate battery condition display so that the
vehicle operator knows the state of charge of the battery pack onboard in
addition to the number of watt/hours used. The reason for this, is that the
battery capacity may vary with battery type/configuration as higher capacity
packs are inevitably developed and each pack (although of standard configuration
dimensionally) will have different safety threshholds if the batteries are to be
maintained in good condition.
The instrument should have it's own memory back-up battery which cuts in should
there be any interruption of the vehicle supply. The back-up charges itself
automatically from freshly exchanged packs, or when outside battery charging
(mains) is under way. The instrument may be assembled from standard commercial
electronic microchip components of 5 - 35 volts, and use dc-dc and voltage
sensing techniques and regulation to ensure low current drain, low leakage and
continued operation in isolation from long periods of non-use and between
battery exchanges. Some environment- hardening may be required.
The instrument may also operate at a higher level as an automatic warning device
for a number of possible errors or longer term problem areas associated with
wear, etc. LCD or other on screen messages or warning lights give advice to the
vehicle operator such as: "low battery please charge or exchange";
"defective battery pack - return to vendor"; "poor connection
between battery and vehicle drop and reload"; "check condition of
terminals".
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 23
PATENT DESCRIPTION CONTINUED
Each time a discharged battery-power-pack is exchanged for a freshly charged
replacement at a roadside forecourt/vendor (as in INSTANT CHARGING OR REFUELLING;
POWER-PACK FORECOURT
MECHANISED VENDING and BATTERY RENTAL SYSTEM headed sections below) the
following information will have to be exchanged: a) energy used b) validity of
battery number and hire agreement c) credit check and monetary adjustment. The
onboard instrument/processing system may also check the battery coded type,
serial number and log the time, place and location the exchange took place
together with the ammounts credited/debited.It may be desireable to include a
printout in-car (useful for checking accuracy of statements from the battery and
electricity supply companies), but this function, being more expensive, may only
be seen as an accessory on upper range models as a printout can be ordered from
any forecourt terminal. After an exchange the kw/hr meter resets to zero and the
kw/hrs used on that exchange is then carried forward only in the memory.
Having exchanged a battery-pack, a typical display might look something like
this:
ACCoUNT NUMBER10000001010 EXCHANGE NUMBER 062
OWN UNITS 1,421.66 EXCHANGE UNITS 1,858.23
OWN UNITS THIS EXCHANGE 1 0 . 60 UNITS THIS EXCHANGE 28.23
BATTERY CONDITION *** 5% *** MILES TRAVELLED 13,119.48
REGENEKATED UNITS 131 18 REGEN UNITS THIS BGE 0. 60
It follows from the above display example that the instrument will also have to
switch from measuring units used to units input while home charging, a role
reversal, then store the units supplied in a memory for later use.The own
supplied units will be deducted at the next exchange, so that the user only pays
the battery supply company for the energy they have supplied. Battery rental is
a separate billing, but the battery rental company will need access to
information of how the customer is using their battery-packs. The above display
example shows that this customer needs to refuel urgently and that their total
fuel bill @ 7.0 pence and 8.0 pence per unit respectively (own -
exchange) is 248.1 68 equalling a cost of 1.89 pence per mile excluding battery
hire. A 30kw/hr pack is used in this example and 120 miles is assumed as the
range per full charge (sports car example).
Battery depreciation can at this time only be estimated from information
supplied by manufacturers seriously intending to produce small batches of high
specification cell assemblies.
A conservative example of a sodium sulphur pack based on general budget
estimates gives the cost of a 15kw/hr pack @ 100 per kw/hr as 1,500.
This pack will give 2,000 deep
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 24
PATENT DESCRIPTION CONTINUED discharge cycles, 400 of which may be from cold
without damage. Thus 2,000 X 120 mile range = 240,000 miles.
1,500 divided by 240,000 miles = .625 pence per mile. Add the 1.89 pence for
recharging to the battery depreciation figure of .625 pence = 2.515 pence. Then
allow an extra penny per mile for the battery supply company = 3.515 pence per
mile. So on cost alone electric motoring makes sense, being 2.913 pence per mile
cheaper than (or almost 50% of) the average 6.428 pence per mile for a petrol
powered car (Battery charging efficiency taken as being 90% overall has not been
worked into the above calculations, neither is servicing included in any
example).
An electrical pulse triggered by or linked to wheel rotation via a counter acts
as a speedometer and odometer. This technique is well known. By cross
referencing the miles traveled, energy economy in miles per kilowatt hour may be
calculated and displayed. Likewise a running total may be memory stored (or the
calculation made from memory stored information when requested).
The onboard instrument must be able to transfer information to a/the forecourt
terminal. A simple way to achieve this would be by transferring battery exchange
information via a magnetic strip on a plastic (credit type) card. A card of this
type may double as user identification and one will be issued with every battery
hire agreement period - initially thought to be for periods of one year.
Some method of detecting unauthorised or expired cards must be built into the
system. This may be achieved by updating the database held at each forecourt
terminal or by direct link comparison.
FUEL CELL GENERATOR/CONVERTER (hybrid)
This present Wolverine system provides that additional power for long range use
may be supplied by a/an onboard fuel cell converter(s), converting hydrogen or
any other convenient convertible fuel in gaseous or liquid form. The fuel cell
conversion need only be required for extended range operation and it must be
remembered that where solar collector panels are fitted solar assistance is
always contributing to the vehicle power requirements when sunlight is available
- thus on average increasing vehicle performance overall. Because of the
increased cost of a fuel cell converter and possibly complicated (cryogenic
tank) storage system, vehicles used mainly for domestic duties need not include
this power source in their original specification, much reducing cost and
complexity. However, it should be made possible in the initial design to add-on
a Fuel Cell Generator at a later date/time.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 25
PATENT DESCRIPTION CONTINUED
To make it possible to realise the option of having the vehicle fitted with a
Fuel-Cell-Generator and at the same time increase the flexibility of the vehicle
format, the
Fuel-Cell-Generator/converter should be made as small and as light as possible
commensurate with the required power output for any particular vehicle
application, 500 - 3,000 watts being the range given by way of example. It
should be sufficiently compact and lightweight (50 - 100 lbs) to enable a person
of average strength to be able to carry it from the/a house to the/a car without
straining unduly, so making the
Fuel-Cell-Generator portable. The position where the
Fuel-Cell-Generator is physically locked on/into and connected electrically,
should be of a standard layout.By this it is meant the locking clips should be
placed logically and in the same position and spacing as in other vehicles using
the
Wolverine system/format. The interface support mountings and the insulated
electrical connections should also be in a standard position/situation with
respect to the locking mechanism and likely location in the vehicle. It must be
recognised that the location within the vehicle may be logically changed
according to intended vehicle type/use. The
Fuel-Cell-Generator may also have an integral storage tank, or a larger separate
tank, bearing in mind the safety storage requirements for this kind of fuel
system and this also should have mountings and connections of a standardised

INTERNAL & EXTERNAL COMBUSTION ENGINE GENERATION (hybrid)
This present Wolverine system provides for a compact generator formed by the
close coupling of a lightweight petrol/diesel/alcohol or other fuelled internal
or external combustion engine and an alternator/dynamo which may be used to
provide a constant supply or pre-set options of output in the order of 500 to
3,000 watts. The generator assembly is/should be designed to be easy to carry by
one person (less than 100 pounds, ideally less than 50 pounds) and is either
equipped with an integral fuel tank or a reserve/holding tank and a separate
fuel tank of a larger capacity.
The motor of the generator should be designed to run at a constant speed; a
speed at which it more/most efficiently converts fuel via the generating
electrical machine to which it is attached, into electrical energy. The compact
generator is located in a position on the vehicle (such as in the boot or under
the bonnet) so as to be easy to load and unload. It will be desirable if the
action of loading onto the vehicle also plugged/connected the unit to the
vehicles1 electric supply/store/control-electrics/electronics.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 26
PATENT DESCRIPTION CONTINUED
When the compact generator is fitted to the vehicle it would have the effect of
turning the vehicle into a hybrid, and give the vehicle the flexibility to run
on an additional fuel source in an emergency. It is intended that the portable
generating unit would not normally be used on day to day or commuting trips, but
only be taken/added to the vehicle for longer journeys or maybe used in
locations overseas where charging stations may not be so readily available and
local fuel supplies are all that is available.
The compact generating unit may or may not be equipped with self starting motors
and may or may not be equipped with a manual pull-type cord starter, both
options depending on intended application and the degree of civilisation at the
place of operation. The compact generating unit should also have the
standardised detachable layout described for the
Fuel-Cell-Generator unit above and should be interchangeable with that unit,
using the same physical securing mechanism and the same electrical connections.
Having the two different electricity generating modules interchangeable in this
fashion, endows the vehicle with a multi-fuel-capacity, giving the vehicle
operator wider choices and fuel options.
INSTANT CHARGING OR REFUELLING
An alternative method of instant charge (refuelling), and by far the most
desireable direction in which development should head, is to unload the
discharged battery pack(s) and connect up a fully charged pack or packs of
similar/identical specification, by exchange. This will be possible only if
battery sizes were to be standardised for each vehicle class and a quick release
connecting mechanism were adopted for the battery packs.
A roadside charging station would either recharge the exhausted pack using on
site stationary collectors or mains supplies, or hold stocks delivered by
charging farms/factories. Each battery pack would be age certified and
credit/debit adjustment applied to a customer who accepted a power pack with a
different certified age. Thus compensating for times when as a customer you
might be obliged to accept a superior or inferior age battery pack.
This assumes ownership of the power-pack by the vehicle operator.
It is thought that the system would average out and that after an initial
familiarisation/try-out period, a system of battery pack rental plus fees for
each exchange, would be adopted/established by manufacturers or entrepreneurs
operating charging stations.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE-SYSTEM. Page 27
PATENT DESCRIPTION CONTINUED
This present Wolverine system provides a method of quick battery pack
change-over/exchange/refuelling an example of which is: where a driver pulls
into a Charging Station's forecourt and positions the vehicle approximately
according to guide markers provided on the forecourt surface or elsewhere. From
inside the vehicle the driver pushes a button, releases a lever, winds a handle
winder down or instructs an electrically powered unloading mechanism or any
other hydraulically or pneumatically operated mechanical mechanism, thus
initiating the disconnection and lowering of the vehicles main power-pack.The
driver then drives/pulls the vehicle forward into another area, over and onto a
fresh battery power-pack supplied by the/a vendor and for this process/purpose
auxiliary/reserve batteries are provided in the vehicle design, as described
earlier. This loading system favours a long thin centrally placed battery
assembly, running the length of the vehicle, fitting into a tunnel that need not
be much bigger than the propellor-shaft central tunnel (7"x9")
associated with traditional front engined, rear wheel drive automobiles. The
tunnel is incorporated into the vehicle as part of the structural
chassis/frame/body construction. A gentle bell-mouth lead in to the central
storage area/channel forms a guideway and is constructed as part of the vehicle
(bumper) to form a foolproof loading system.The driver continues driving slowly
forward on auxiliary/reserve power until solid contact is indicated by a clunk,
buzzer or by the illumination of a warning light. The new power-pack is then
secured and connected to the vehicles circuits using the reverse action to the
unloading procedure. This action also lifts the power-pack up into the central
tunnel storage/holding bay, a distance of approximately six inches (more on
commercial or off-road vehicles). Connection of the power-pack is ensured by
large insulated safety pins or other shaped connections also with built in
foolproof features, to prevent the accidental loading of a power-pack the wrong
way round and any hazard of electrical contact.
This particular longitudinal drive over system does not require heavy investment
in the refuelling station forecourt area and is seen to be ideal for use in
countries requiring minimum start-up costs and is also seen as an ideal interim
system until public acceptance of electrical vehicles has once again been
gained. As a bonus, the driver never actually has to get out of the vehicle to
refuel, which may be useful in inclement weather.

PATENT DESCRIPTION CONTINUED
POWER-PACK FORECOURT MECHANISED VENDING
Power loading or mechanised powered vending systems where power-packs can be
unloaded and replaced from any direction; side, front, rear or underneath, make
it possible for vehicle designs to be every bit as flexible as vehicles using
internal combustion engines. This present Wolverine system includes for such
powered loading of traction batteries one example of which is given in the
following example:
The power-packs loaded by a mechanised vending system can be situated in
locations that the drive over loading system could not work because of space or
other considerations.Slightly raised steel rails, where a driver drives between
the rails and stops when making contact with another steel bar placed
temporarily ahead of the vehicle is a system of ensuring positioning the car
within acceptable limits. Warning/guide visual and audible signals, instruct the
driver as to vehicle position acceptability. When the vehicle is positioned
correctly, the driver is signalled to stop. A loading arm coming from within a
sub-surface pit/room approaches from underneath the vehicle, locates and
demounts the battery-power-pack via a quick release and foolproof catch or
securing/connecting mechanism and carries the discharged battery-power-pack, to
be exchanged, away to a store.Another loading arm coming from the other side of
the pit area, carries out the reverse operation by loading the vehicle with a
fully charged battery-power-pack, securing and connecting the battery-power-pack
in the same sequence. The fully charged battery-power-packs are drawn from a
store fed to the loading arm and this complete loading sequence is described as
either a cross-flow or a transverse-flow system.
Longitudinal-flow systems can be made to work with equal efficiency and the
description of the transverse-flow system given here is only to be taken as an
example of how the system may be applied in a given situation and not to be
taken as definitive or in any way limiting to the application of the invention.
Additionally, a fully automatic mechanised vending system using slot machine
technology will ultimately lead to unmanned 24 hour refuelling stations.
Twenty-four hour or automatic vending forecourts/service stations will need to
(should) be able to accept a variety of different methods of currency exchange.
As credit cards and direct currency transfer cards and token exchanges are
already becoming increasingly used by the public, this would seem to be a
logical path to take.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 29
PATENT DESCRIPTION CONTINUED
The mechanised or automatic loading system may be implemented in a variety of
mechanically, hydraulically, pneumatically or electrically actuated
combinations. Automatic vending machines are well known in a number of product
applications: cigarettes, chocolate bars, hot drinks, jukeboxes and cashpoint
card machines and car washes, to name but a few.
Because of the unique unit transfer arrangement of battery-power-packs for some
form/token of monetary exchange, an automatic or 24 hour vending machine
(franchise) operator will require only to ensure his/her forecourt machinery is
supplied with charged power-packs and arrange for the discharged power-packs
taken in/by exchange to be re-charged.
Care will have to be taken in the design and placing of the battery power-packs
within the vehicle design. The power-pack itself will represent a substantial
investment to the vehicle purchaser, hirer, vendor or whoever else has an
interest in the battery-power-pack(s), i.e. the owner or, in the event of an
insurance claim, the insurance company. Therefore, maximum protection from
accident damage should be allowed for. At this time it is thought a central
location, low down in the vehicle or coming from underneath, would be the safest
option.
This conclusion is draw from the frequency of front and rear end collisions
statistically shown as being by far the greater proportion of common contact
damage.
BATTERY RENTAL SYSTEM AND ELECTRIC SERVICE STATIONS
A customer using an electric vehicle equipped with this present Wolverine system
of instant power-pack refuelling need never purchase outright a battery
power-pack, but could optionally rent a power-pack from a franchise operator;
that is a person, partnership or company who makes it his/her/their business to
rent, lease or hire-out battery power-packs in such a way as to make a profit in
a business-like way, as a business. At yearly or other appropriate intervals the
rental agreement would be renewed for a sum, to cover administration costs. Each
time a battery pack is exchanged for a fully charged replacement, a service
charge is made. The service charge carries a proportion for depreciation,
charging, handling and a margin for profitable operation by the vendor or
franchisee.In this manner the vehicle user only actually pays for the mileage
he/she covers and never has to lay out a large lump sum at an inconvenient time.
A system of registered users, where at the time a rental agreement is taken out
on a battery-power-pack, the person taking out the agreement is automatically
entered into a database and is then given an identifying code contained in the
form of a magnetic-strip and possibly attached to a plastic (credit type) card,
or the battery-power-pack, or the vehicle itself, for the purpose of
forecourt/vending station identification, may be introduced. The vehicle
operator may
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 30
PATENT DESCRIPTION CONTINUED then be identified by inserting the card into a
terminal, or by identification of the vehicle or battery-power-pack. After
verification and validity has been established the driver/operator may then key
in instructions as to his refuelling requirements.The new transaction would be
recorded and the customer debited automatically. A partially discharged
battery-power-pack will have the remaining charge recorded and a credit
adjustment automatically made against the charge levied for the replacement
battery-power-pack.
This system of adjustment applied to each exchange of battery-power-packs will
ensure electrical energy that has been previously paid for, will be carried
forward and the vehicle operator will not lose by early exchange, when, for
example, the battery-power-pack is getting low and a convenient service
establishment is to hand.
From the point of view of the service station company, every transaction on
their forecourt(s) will have to be recorded to ensure efficient stock control,
customer billing and other associated procedures. As in a bank terminal
customers will also benefit from access to information of their own account,
hence usage and current state of affairs. A limit will be applied to each
customer automatically and this will be agreed subject to status at the
inception of any hire agreement. The terminal will not release battery packs if
the credit limit has been reached. The only way to overcome this condition will
be for the customer to make fresh payment into his/her account of sufficient
ammount to allow future exchanges.
A forecourt terminal will require a read/write card swipe or insertion slot much
the same as the onboard vehicle battery-management-instrument. Early
developments could be based on Personal Computer hardware being economically
available. In a PC based terminal the most expensive part of the system would
probably consist of the operating software.
Future developments will require the system to accept payment cards, or on
instruction after Personal Identification Number (PIN) keying, transfer funds
from one type of account to the battery account. Because of the number of
options open for future trading and the not-knowing in which direction
development will go, an expansion facility must be built in to cover the
eventuality. This may take the form of plug in slots as on a PC, or link up with
a Bank style/type clearing system.
An alternative method of transfering information, from the in car
Battery-Management-Instrument to a forecourt terminal, of energy used, would be
to use a short range radio link.
Customers would still be issued with some form of identification card, as
described above (or other identifying medium) but the card (or other medium)
would only need to be inserted into the dashboard mounted instrument. The card
(or other device) could thus act as a security key either
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 31
PATENT DESCRIPTION CONTINUED supplanting or supplementing the conventional type
of tumbler lock ignition key used on petrol powered vehicles. The vehicle
operator/user would then key into the instrument keypad instructions of his/her
requirements. Verification and credit exchanges would take place as previously
described using a radio link and decoder instead of the magnetic
storage/transfer medium.
Difficulties may arise if, for example, a vehicle operator/owner were to
purchase a power-pack outright. The operator/owner in this instance might be
hesitant in exchanging his/her new power-pack for one supplied by a roadside
vendor, which may be half way through its useful life, in'so doing he/she will
be losing on his/her investment.
Because of this problem eventually surfacing, it is advised that a customer
purchasing an electric vehicle equipped with the Wolverine loading/refuelling
system would rather take out a rental agreement at the time of purchase. The
only time this might not be practical is when the vehicle is to be used in a
remote area, maybe where no roadside vendor/charging stations have yet been
installed. Even in this set of circumstances it may be possible for a person
with a privately owned pack, to later join the rental system after age and value
assessment of his/her battery-power-pack, when the rental company would purchase
the privately owned pack at the time a rental agreement was taken out.
It must be emphasised that this present battery-refuelling/loading/unloading
invention relates to the concept of incorporating a quick-release
battery-power-pack loading and unloading mechanism/system into/onto a motor road
vehicle for the purpose of convenient and speedy refuelling from roadside
vendors/service-stations and in no way restricts the invention to any particular
loading/unloading/connecting type, design or method and/or any particular
capacity, output, format, size or shape of battery-power-pack, but by giving
example and description of certain types and methods, in particular the
Longitudinal-Tunnel-System, by way of the suitability of that system, for rapid
incorporation/more easy adaption, into/onto current motor road vehicle designs,
endeavours to make it readilly apparent to the reader the basic requirements
of/for the system to work.

PATENT DESCRIPTION CONTINUED
Within present day Great Britain, electric vehicles are not required to
contribute to any Road Fund. Under the Vehicle
Excise Act, 1971., they are exempt and require no license.
No duty is payable on electricity supplies used for transportation either and it
would be difficult to introduce any system which taxes energy for whatever
purpose, that is collected free from nature. Unfortunately, it would seem
reasonable to expect that this happy state of affairs will not continue
indefinitely and any interim advantage should be taken as a temporary bonus. The
powers that be, will almost certainly require to change the rules/law once the
numbers of electric vehicle users become large enough to contribute to road
surface erosion. It must be remembered that the very reason for this state of
the law, was/is to promote more widespread use of electric vehicles throughout
the land.
Laws relating to electric vehicle usage vary from country to country and the
laws pertaining in Great Britain at this time are only given as historical
reference.
VEHICLE MECHANICS AND STRUCTURE:
CHASSIS
More use of lightweight materials e.g. aluminium, plastics and composites and
efficient body-airflow design are essential ingredients for overall vehicle
performance as confirmed by efficiency development being carried on by present
day motor vehicle manufacturers. The additional expense of using such exotic raw
materials will be offset against a longer vehicle design life. There is no
reason other than a manufacturers need for new sales and the whims of fashion
generated by those same car makers, why a vehicle should not last 40 or more
years. A more responsible attitude to use and re-use of the Earth's resources
will have to be adopted by the governing powers and set down as guidelines for
industry. I myself drive a 24 year old
Volkswagen Beetle, only modified to bring the performance in line with what is
currently expected - the basic chassis, bodyshell and engine remain as
originally designed by
Professor Ferdinand Porsche. This ideaology is not intended to restrict
performance or style or indeed enjoyment from the use of the motor vehicle, only
to rationalise the ecological impact of man on his environment.
For the battery exchange system to be effectively incorporated particularly into
a/any traditional passenger vehicle design (car) without altering the publicly
accepted: shape, handling, useable space and functional practicality, it will be
necessary to rethink the structural layout basics of the chassis component (floorpan)
of a conventionally built unitary shell. It is not possible to simply add-on
such a large item without destroying some of the above criterea. To
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM.Page 35
PATENT DESCRIPTION CONTINUED integrate the loading mechanism effectively a
complete rethink is necessary leaping over/ahead of chassis evolution over the
past 50 years some of which is not relevant to the new problems posed by the
incorporation of such a large loading mechanism, while at the same time using
any applicable advances/techniques already developed. It is desireable for the
the vehicle structure and battery-power-pack loading mechanism to be one
integrated unit.
The battery loading assembly of a longitudinal design necessitates a tunnel from
the front of the car to the back which is open from the underneath for the
length of the vehicle. Thus transverse load bearing members will have to take
loads over the top of the inverted "U" section tunnel which in most
cases will (obviously) form a rigid backbone member or beam. The open underside
of the longitudinal backbone will be prone to flexing where the sides open away
from each other or close together, under load. Because of this the transverse
load bearing members will also have to form a rigid (triangulating) stiffener to
prevent opening of the backbone tunnel sides. The loads through the transverse
stiffening members will have to travel up and over/across the inverted
"U" section tunnel.Additional torsion boxes incorporated as sills can
be used in the normal way, joining with the transverse members and a braced
floorpan included to take passenger loads, the whole assembly providing much
additional rigidity.
Fortunately, monocoque, unitary spaceframe or beam construction lend themselves
to the incorporation of a purpose built battery-power-pack loading mechanism
most acceptably.
Another benefit of a low slung battery-power-pack, centrally mounted
longitudinally coupled with evenly spaced drive motors, one per wheel, is the
perfect balance of weight distribution and low centre of gravity that has never
been acheived with any petrol powered vehicle. The benefits in terms of improved
standards of roadholding, braking stability and possible separation of heavy
mechanical components from human occupants in the event of a collision, are
incalculably beneficial contributions to road safety.
SUSPENSION
Any reduction in the number of components and complexity should lead to longer
term reliability of a working mechanism/machine. The incorporation of a wishbone
type suspension where either top or lower wishbone arms is/are replaced by a
wishbone shaped single leaf spring or a single leaf third link and steering arm,
is an addition to the
Wolverine electric vehicle system allowing positive engineering benefit. By
using the leaf spring correctly in any particular application negative camber
change closely
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 36
PATENT DESCRIPTION CONTINUED following that achieved by conventional unequal
length wishbone systems may be attained. Any of the ways describing the use of
this system have the advantage of reducing the number of components, clutter and
unsprung weight.This present system uses the wishbone shaped spring or single
leaf spring third link and/or flexible/spring steering control arm in one of
three ways:
A. As the lower wishbone component, fixed in such a way as to have the spring
topside in compression and bending under the load of the vehicles weight upwards
or away from the ground so as to straighten and lengthen the spring arm
proportional to load applied. The spring curving downwards towards the ground in
the normal position or when the vehicle is at rest.
B. As the upper wishbone component or third link, fixed in such a way as to have
the spring topside in tension and bending under the load of the vehicles
weight/cornering forces upwards or away from the ground so as to increase the
bend of the spring arm and reduce the length in proportion to the load applied.
In this application the steering arm control rod will also have to be able to
flex in a close match to reduce its length by the same proportions.as the main
spring component, to maintain a true vehicle line/course under cornering
conditions.
C. As a combination of A. and B.
Spring taper design, length and material choice can be selected to allow almost
any geometry set-up, spring rates, etc., to be applied as handling and cornering
characteristics.
Additionally, chassis design will benefit from having shock input loads
distributed from a point lower than is possible with other suspension designs,
also simplifying chassis design and calculations during design and lowering the
vehicles centre of gravity.
VEHICLE CONTROLS
Motor road vehicles, including Cars, Vans and Trucks, use a system whereby five
separate levers and a large geared wheel have to be co-ordinated by the driver
to effect directional and velocity change or control. The system is clumsy,
taking many hours of rehearsal to reach a stage of familiarisation where a
person having normal faculties can control/drive a vehicle so equipped.
Moreover, the expense of manufacturing and fitting many separate control
devices, could be reduced if combined in one compact unit. Additionally, the
compactness and simplicity of the combined lever system, lends itself to
coupling with electrical/electronic sensors/transducers - a desirable asset if
the passenger car and delivery van is to progress with computer aided driving
techniques in the future.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM.Page 37
PATENT DESCRIPTION CONTINUED
This present Wolverine system groups all the driving controls onto a single
double jointed lever, or lever sharing the same axis/pivot point, or joystick,
located comfortably for the seated Driver. One handgrip or a split handgrip
station forming two separate handles is/are fitted atop the joystick (transversly
approximately 150 millimetres apart for the split handgrip station). The split
handgrip station enables either hand to be freed more easily when required for
supplementary control usage. The split handgrip station also provides a more
even application of input effort. However, it is possible to drive a vehicle
with single or split handgrip stations, one/single handed. To accelerate the
vehicle, the
Driver merely pushes the lever forward. To steer, the Driver pushes/pulls/points
left - to go left, or right - to go right.
To brake the vehicle, the Driver pulls back on the lever. The accelerating and
braking functions may be reversed, but for application on electrically powered
vehicles are considered to be more practical as stated.
Conventional braking components and systems that are well known, for example:
hydraulic expanding shoe (M.Loughead 1920 later lockheed) and/or disc caliper (F.W.Lanchester
1902 & BR<
Dunlop 1953-4) arrangements, may be connected to the joystick by having a master
cylinder mounted on the joystick shaft connected by a push-rod from the handgrip
station(s) and then with flexible hydraulic hoses and/or remote fluid
reservoirs, master-cylinders and/or by flexible wire (Bowden) cable
connections/linkages. Servo assistance may also be applied, though not as a
necessary requirement for the braking system to work, but rather an addition for
the purpose of reducing a driver s input effort and making the driving act less
demanding.
As with most vehicle accelerator controls, a simple inner-wire (Bowden) cable
with a captive/end-stopped flexible wound wire enclosing outer-casing/cover,
usually spring tensioned, may be used, being by far the simplest/easiest method
of transferring light lever applied loadings and a well known automotive
application. Hydraulic couplings and circuits will in this instance be an unduly
complicated and costly method of load/movement transfer as will any solid
coupling rod, hinge, ball-joint, lever, sliding-rod or gear method that may be
applied with great difficulty. The cable method may attach to any convenient
part of the handgrip station(s) movement.
However, it is suggested that the nipple, ball, pinched or pin-pivoted cable
end, meets with the lower part of the brake push-rod to minimise clutter about
the main shaft and prevent unnecessary/additional cable bending. The cable may
then join conveniently with the speed controlling devices of/within the vehicle.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 38
PATENT DESCRIPTION CONTINUED
A parking/emergency brake is incorporated in the joystick system, being operated
by a shrouded lever set against the joystick main lever/shaft. The shrouding of
the lever is designed to protect the Driver against accidentally initiating the
parking/emergency brake function. The lever may be positioned either left or
right and hinged or pulled, in operation, away/towards the Driver. The parking
brake is a direct mechanically operated system via hinges, levers, cables or
rods.
A pod or console is placed approximately one hundred millimetres before the
joystick handle(s), within easy reach.
The pod or console contains/holds the usual electrical switchgear to control
the: Ignition/Power-on switch,
Indicators, Lights, Wipers and Horn. The Ignition/Power-on switch may work in
conjunction with (double as) a high security device which may be activated by:
Coded key-pad,
Infra-red wave decoding, Voice-recognition, Fingerprint- scan, or Ultrasonic
identification operation, in any order or combination. The security device or
combination of devices forming a unit, is located on the upper forward facing
facets, left or right, ahead of the switches operating the: lights, indicators,
horn and wipers of the motor vehicle. The pod or console described, is attached
to and moves with the joystick to provide constant location relative to hand
position, whilst driving.
The inclusion of a facility to allow adjustment is engineered into the joystick
system to provide for raising or lowering of the handgrip station(s) relative to
floor or seat position, and lengthening or shortening of the shaft(s) and
linkages relative to dashboard and handgrip(s) position. The adjustable system
being geometrically arranged so that the ratios affecting feel remain unaltered.
Thus any vehicle fitted with the joystick system, may be set up by a driver to
match any other vehicle also fitted with the joystick system.
This will provide a method of layout standardisation to alleviate
familiarisation problems, when changing from one vehicle to another.
The joystick action is geared (mechanical advantage ratios adjusted) to allow a
person of normal strength to be able to operate the steering action, without
straining unduly. Power assistance may be added by electrical or pneumatic
servos or by hydraulic means in parallel with the direct mechanical linkages of
the joystick system, but is only a means of easing the steering movements and is
not an operational necessity.
The joystick steering, left-right, motion may connect with conventional
rack-and-pinion, recirculating-ball or any of a number of different and well
known systems via suitable: Rose,
Metalastic or other Ball and Hinge joint arrangements.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 39
PATENT DESCRIPTION CONTINUED
By way of example: a tube/bar/rod or parallel-double-rod, equating the rack
section of a rack-and-pinion system, is set in bearings at either end (the
bearings being fitted securely to the vehicle frame) so that the tube/bar/rod is
free to move transversly from wheel to wheel by a sufficient clearance movement,
to allow the normal steering action when track-rods or tie-bars at either end of
the tube/rod/bar meet via suitable ball type joints, with the steering control
arms on each upright or kingpin. The joystick main shaft is set in steel roller
bearings, longitudinally, at its lower end (close to the floor) so that a
transverse arc may be described from left to right.The single or split handgrip
stations are located at the top of the joystick shaft (near the drivers hands)
and is/are set in plain bronze bearings, transversely, so that the handgrip(s)
describe a smaller longitudinal arc forward and back. The combination of these
two arcs/actions gives a two dimensional movement to the joystick, as felt by
the driver holding/moving the handgrip(s). Motion left and right, joins with the
bar/rod/tube via a connecting tube taken from approximately 33% up from the
floor pivot-point on the joystick main shaft. The connecting tube has ball
joints on each end and is adjustable for length. The opposite end of the
connecting tube meets with the steering rod/bar/tube near the end of the
rod/bar/tube on the opposite side of the vehicle to the drivers seat. if the
driver has a central position within the vehicle, either end may be used.Thus
the left and right movement of the joystick main shaft pushes and pulls the
rod/bar/tube and in so doing changes the steering wheels angle in relation to
the vehicles direction of travel and effects vehicle steering.
The system described, when used in the following combination is a hybrid vehicle
control, especially suitable for use on electric vehicles, being a combination
of General Motors power operated electronic vehicle joystick control, patent
number
GB 0883554 A of 1959., being the speed and braking components, and my own
manually operated mechanical joystick control patent number GB 2218187 A of
1988., being the steering and braking components, combined together and with
additions to both systems (especially speed and braking):
Acceleration - is effected by applying a variable controlling voltage input via
a back and forward movement of the joystick handgrip(s), to the vehicle's
speed/power controller.
B60 K & - COMPREHENSIVE ELECTRIC MOTOR ROAD VEHICLE SYSTEM. Page 40
PATENT DESCRIPTION CONTINUED
Braking - is effected by conventional mechanical and/or hydraulic systems that
are well known, being supplemented by regenerative retardation of the main drive
motors when switched to a generating mode and by the use of said generated
electrical energy or electrical energy stored in the vehicle's energy storage
system, to apply electrically powered servos as power assistance or servo
assistance to the braking system.
The joystick handle(s) movement backward and forward initiating switching
instructions and apportionment to the regenerative and
electrical-servo-assistance-unit(s).
Steering - as described above.
Drive-by-wire is a term applied to motor road vehicles where all of the driver
control inputs are fed to the mechanical actuating components via electrical and
electronic means.
Vehicles equipped in this way have no direct mechanical links from/to the
driver. Because of the safety requirements by governing bodies such as the
Department of Transport and/or the ECE (EC directives) and/or USA motor road
vehicle
Construction and Use Regulations and any similar Regulations as applied to/by
any other Country's Legislation, vehicles with no direct mechanical link to
basic functions of a motor road vehicle, consisting essentially of Steering and
Braking functions, are deemed not to be suitable for use on the public roads.
Thus, drive-by-wire joystick applications may not gain the Type-Approval
necessary for sale to the public.
A hybrid joystick system overcomes this problem by using direct mechanical
linkages in the areas considered necessary for safe/emergency vehicle operation.
Only the accelerator control of a hybrid system is not directly linked to the
motor speed control. As this is quite normal practice in electrically powered
vehicles, it follows that hybrid joystick systems will be especially suitable
for use in conjunction with electrically powered motor road vehicles.

PATENT DESCRIPTION CONTINUED
The vehicle joystick control system, descriptions and applications provided
above are in no way to be taken as being definitive or limiting to the concept
of joystick driving controls in motor road vehicles, but are given as layout
examples/methods, so that the reader might more easily understand how the
invention may be enacted and the basic requirements for the/a system to work in
a motor road vehicle.
AERODYNAMIC FORM AND SEATING LAYOUT
The most obvious change suggested as being a desirable incorporation to any
vehicle structure, is the adoption of the 1-2-1 seating arrangement which will
allow major re-working/management of the airflow around and over any vehicle by
more closely matching a vehicle's form in plan view and side elevation to the
ideal of a pure teardrop. Applying refined principles of aerodynamics to the
generally accepted vehicle form can in no way achieve what is theoretically
possible by altering the starting point vehicle form to more closely approximate
the ideal.
By changing the seating positions it is possible to improve radically the
starting point from which detail refinements can be made. Assuming minimum
frontal area commensurate with freedom of movement essential to passenger
comfort this present system places the driver ahead of two centrally located,
side by side, seating positions, with a further single seat behind in the rear
of the vehicle. The rear seating position is also centrally located and may be
facing in either direction, accepting that if it is facing towards the rear of
the vehicle aerodynamic purity will be even greater.
Research into driving habits shows that on most occasions a car is used by one
person only. On the occasions a car is occupied by more than one passenger there
are usually two or three people in the car. It is very rare indeed for all of
the available seats in a vehicle to be occupied. Common sense should tell us
that if we must have four seats in a motor vehicle, then the ones that are only
occupied occasionally or least of all, need not be prominently located and the
regimentation applying to traditional seating positions is due for reevaluation.
The driver being centrally located at the front of the car is logically better
placed to observe traffic conditions. Ergonomics of the vehicle layout are also
improved. A centrally placed driver is also less likely to be injured in a
collision.Additionally, a motor road vehicle with a central driving control
position, is suitable for use in Left or Right Hand Drive applications and those
countries pertaining to. For all of these reasons a 1 - 2 - 1 seating position
will benefit those using the vehicle so equipped.

PATENT DESCRIPTION CONTINUED
CONCLUSION:
This present system is enhanced greatly by the percentage contributions
described and the high efficiency drive, helping to balance the need to keep
weight to a minimum and pass drive to the road surface without geartrain/driveshaft
losses. Drag caused by the vehicle form cutting through the air can be reduced
considerably and the vehicle still remain practical. Frictional rolling
resistances have, as far as is theoretically possible been reduced to a minimum,
bearing in mind the present day tyre compounds/tread designs available.
This present comprehensive system/formula can be made to work acceptably well
with total vehicle drive output in the ranges 1 to 100kw. Proportional
adjustments will have to be made to solar charging areas and battery store
capacities for vehicles with/requiring the higher output ranges (i.e. over 16
kilowatts).
The inherent handling characteristics, being much improved by the ideal weight
distribution made possible by incorporation of this present comprehensive
Wolverine system, i.e. batteries would normally be located low down and in an
easy-to-service configuration giving a balanced layout that would be difficult
to emulate with any internal combustion engined vehicle and there being no other
heavy item or component necessary to complete a vehicle mechanically or
structurally, and the motors being situated as suggested; tyres can be reduced
in width and tread designs altereddeveloped to reduce the rolling resistance.
Any reduction of the rolling resistance gained by this method, would in effect
increase the efficiency or range of the vehicle.
It is necessary for the public to be re-educated into accepting higher initial
investment/outlay for longer term gains and come to terms with a change in the
way we view and use renewable and non-renewable resources. A base model four
seat vehicle with a life expectancy of twenty-five years, might cost double its
internal combustion engined rival until volume sales evened out research,
development, tooling and marketing costs of the/a new product. However, the
overall benefits of running such a vehicle will be seen to be not only
environmentally friendly, but also long term, much more economical.
