It's just my understanding that the batteries today aren't the limiting factor in charging. Actually getting the current out of the wall without melting the wires and setting the house (or the charger or whatever) on fire. It makes sense, too. Figure a car is going to need at least in the range of ~50HP / 50 kW to have not absolutely pathetically anemic performance. If you've got a 50A circuit, you still need a kilovolt. If you've got a 250V outlet, you still need a 200A circuit. Either way, you're looking at something comparable to the main feed at the meter from the utility, just to keep up with the car's power potential. And, no, you're not typically driving full-throttle...but you're still drawing an awful lot of current on the freeway. If you want to charge as fast as you draw...you're going to need something that significantly outpaces the main line to your house. b& _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
