This weather we are having is great for getting best performance out of your EV batteries.
I have noticed less voltage droop, graeter range and higher terminal voltage.
maybe there is something in having a heated battery compartment for winter.
Warm battery
Oh yes , warm weather is soooooo much better for batts of all types as the hotter weather makes the chemicals work much better.
Of course dont forget it will cause flooded LA's and any liquid filled batt to use slightly more water due to evaporation

Hi Floydster - I would get your battery off a cold floor either on timber or better still in an insulated box perhaps some of that very thick polystyrene they use when laying floors in houses.
Are the batterys sealed or wet batteries. If sealed you may want to think about completely enclosing them, if wet batteries if you fully enclose you ought to have some sort of air extraction to get rid of any acidic fumes.

I am interested in this, and want to write a short article on the shorter range of EVs in winter compared to summer, both for lead-acid and for Li-ion batteries. I have a little data from our own measurements but would greatly value info. from any other member. Alan Ward

Li-Ion
I have my batts in a temp controlled foam sandwich at a constant 25C when in use as some of you know. They still work better once they warm up to 40C after 25 miles or so
Low temp means longer chemical life, higher temp = faster chemical reactions = better performance but shorter life
I will eventually have to run my cells at 50C+ in a few years to get acceptable performance as the internal resistance builds up!
