Ah - I didn't realize that. I assumed the battery warmer was on only when plugged in.

In the couple of winters I have driven my EV, I un/fortunately never used it regularly enough to keep the pack snuggly warm.

In that case, another cold weather strategy is to time the recharge so it finishes just before you're ready to use the vehicle (assuming it's OK for your particular chemistry to let it sit partially discharged ... not lead-acid friendly, but OK for Li / NiMH, as I understand it).
