Hi Dennis, I have used my Elise EV with 50Ah cells through some pretty cold winters (-15C) here in the UK with few if any problems.
You do get a larger voltage sag when accelerating but then you don't need to as much when its icy. Range may be reduced but then it is anyway with all the heating, wipers and head lighting usage. The one thing you must remember is to never charge when the cells are below 0C (32F) as it damages them. I always plug in after a journey when the cells have heated themselves so its never really and issue.

I know that the cold weather will affect my range, but need some information on what I'll see. Pack is (50) Calb CA-180 AH Cells. Total @ 3.35V ~ 30,000 Whr's. 21,000 Whr's @ 70% Current Average for ~ 50 trips is ~ 240Whr's per mile. Will I see any different readings on my instruments ? - Higher current draws. - Higher Whr's per mile. - Larger Voltage sag. - ? ? ? - Or do I just need to assume I have a smaller pack. If so approximately what %. Just trying to make sure I don't drain the pack, leave myself stranded, and possibly damage the cells. - Thanks; Dennis Elsberry, MO http://www.evalbum.com/1366 http://evalbum.com/3715 -------------- next part -------------- An HTML attachment was scrubbed...
