What is the real cost of motoring these days? For a petrol or diesel fuelled car it is rising so quickly that any example we give here will probably be out of date when you read it. But as of the 1st of May 2012 with petrol in the UK @ £1.40 a litre, if your car returns 50 miles per gallon, then the cost of each mile in fuel alone is:-
4.55 x 1.4 / 50 =
To this you should add higher road fund duty, congestion charges, oil changes reciprocating engine maintenance (i.e. virtual replacement every 150,00 miles after emission testing) and the damage to our ecosystem. But let's stick to the basics for now.
The equivalent for an EV is not quite so simple but we can assume 5 miles per Kw/hr where for example the GM EV1 was returning 6 miles per Kw/hr in some tests. With the cost of electricity in the UK running @ 13.7 pence per Kw/hr and 4.6 pence on economy 7, once again it is safe to assume 14 pence per Kw/hr, even though we know energy may be sourced cheaper. Then the cost of each mile in electricity is:-
14 / 5 =
It's a no-brainer and only EVs can use wind and solar farm generated clean electricity; renewably long after the oil wells run dry. The sums still stack up in favour of EVs taking into account battery depreciation versus I.C. engine depreciation.
Motor manufacturers who are interested in exploring the possibilities for this technology should contact us. We will be pleased to advise if a particular floorpan of any of your production vehicles may be adapted easily to use the Ecostar™ cartridge refueling system.
Other battery replacement systems do not provide any level of autonomy for the owner of an electric vehicle. They would be totally dependent on there being a service station, to be able to exchange or service their cartridges. With the Ecostar™ system, an owner may exchange cartridges at home, at a local shop or other cooperative, or at a service station.
This is only possible with a battery cartridge loading mechanism that is a part of an EV - built in. Yet the vehicle suffers no significant weight disadvantage with clever design. This also means that when Energy Companies build service stations in cities, etc, that the service stations designed to cater for the Ecostar™ universal battery cartridge are that much less complex, hence, cheaper.
