Re: DC / AC Efficiency?
There are some lithium batteries that can be recharged in 10 min or less (nanosafe is one of them), but you have to have some serious power in your house to dump that much energy into your car in such a short time, even a 240v outlet would not give enough juce for that. Other battery chemistries would reduce the recharge time compaired to lead acid to a point, but you are still limited by your household current, so a 10 min recharge is not likely at home (although with enough $$ anything is possible).
