I drove a Think Neighbor around Boulder in the winter back in 2003. It wasn't too bad. I kept it charged in whenever not driving it, if possible, and didn't notice much power drop. I never got close to full range on a typical day anyway, so wouldn't have noticed range drop. It was rear wheel drive, and occasionally, I did get it stuck for little bit, but the battery weight actually made it pretty good -- it would go through a few inches of snow usually. The stuck times were when I tried like 8" deep alleys.
The EV bug is not so happy in the cold with the old AGMS.... I took them out last week, awaiting good enough weather to installed the new lithiums. It was reluctant to even move with freshly charged AGMS -- at about 15F... (controller cuts the current at 62 volts, on a 72 volt bank, and when they were that cold, and old, they sagged down to 62 volts with only about 80 amps). And... it has lousy tires for the snow. I thought I was stalling the motor at 80 amps once and it wouldn't move. Under further investigation, it was not stalling, but spinning slowly in the ice, not going anywhere :) On Sat, Jan 11, 2014 at 2:24 PM, EVDL Administrator <[email protected]> wrote: > On 11 Jan 2014 at 15:12, Cal Frye wrote: > > > Daytime temps here in NE Ohio dipped down to -9F, and I continued to > > drive my lead-acid GEM around town. > > I've jumpstarted ICEVs several times with EVs.
