Almost makes sense. So you estimate 50% of the potential energy went to the regen system. And you also estimate that about 25% of the potential energy ended up in the battery. So I'm concluding that your regen system is about 50% efficient. Correct?

Are you saying that the regen recouped about 24% of the energy expended in that scenario?/" I mean that the energy put into the batteries going down the hill was 24% of the energy taken out of the batteries going up the hill, and that about half the potential energy of the car at the top of the hill was put into the batteries going down. The rest went to work against drag and rolling resistance forces, drive train losses, and motor/controller losses. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-Fiat-500e- EV-close-to-perfect-tp4668392p4668519.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ 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) _______________________________________________ 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)
