I have an uncle in San Francisco who has an Honda Fit EV -- part of one of their limited lease public trials. He lives near the top of the hill just south of the park. When he drives down to the park, regen "overfills" his batteries (I'm sure Honda intentionally doesn't have the wall charger take the batteries to 100% just for such situations) and, when he gets back home, the pack is back down to merely regularly full. It doesn't quite use zero energy for the round trip, but the efficiency he gets that way compared to an ICE that would just be making heat all the way down...well, it might as well be zero energy.
...and, oh-by-the-way, the energy he _does_ use is cheap-as-dirt electricity.... b& > On Aug 3, 2014, at 8:48 PM, EVDL Administrator via EV <ev@lists.evdl.org> > wrote: > >> On 3 Aug 2014 at 19:58, Roland via EV wrote: >> >> You would think that going up and down a hill would take more kwh's more than >> the same distance you would drive on a level grade. > > This is where regen comes in.
