Sorry...I had in mind overnight home charging, with the assumption that the 20 kWh you get from 12 hours @ 110V / 15A is going to be good enough for as many miles as nearly everybody is going to need in a day, especially given the types of efficiency figures we're headed towards and that Lawrence was advocating. At 250 Wh / mile, that's 80 miles. Even at 500 Wh / mile, that's still 40 miles, the range that Chevy targeted for the Volt as "almost good enough for 100% electric for almost everybody." Yes, there will be exceptions...but how many people regularly drive more than 40 miles in a day, and, of those, how many are going to want to do so in an EV that's only doing 500 Wh / mile? Even more important...how many people are going to want to spend lots of extra money on an at-home fast charger if overnight L1 charging always leaves them with 80 miles more in the morning than they had at the end of the day before? 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)
