Manukas points are valid. A ultracapacitor has a higher acceptance rate but does not store for long periods but has enough storage time to be the accepted rate of acceptance for the battery so a combination makes sense for this concept, would love feedback via posts cheers

Sigh-yet another e-car posting that fails to consider electrical charging basics. Irrespective of advances in battery technology (which like many others I'm very enthusiastic about),charging in "just a few minutes" requires ENORMOUSLY greater currents than the mains supply & wiring can deliver! Even 3 phase at say 415V & 25 Amps will only deliver ~10kW per second (thus 10kJ)into the e-car's "tank". Motor fuels have calorific value of ~40MJ per litre, meaning it'd take 40,000kJ/10kJ or 4000 secs (~1 hour)for even a litre equivalent to be stored in the car! Although of course e-cars are wonderfully efficient,it'd still take 8-10 hours (& thus all day/overnight)to give the batteries a decent energy reserve. In spite of their hassles & costs, existing motor fuels are extremely concentrated stores of energy - even a small ~100mL cup of petrol has about twice the energy (~3.6MJ or the equiv. of a kWh "unit")than a fully charged 12V 40Ah car battery (12x40x3600 =~1.8MJ)
