The battery also does not heat up as fast, for the same reasons.oxothuk said:Since it is 50% larger I would presume that the 62kWh battery does not cool down as quickly in extreme conditions as the 40kWh battery.
You have to look at the minimum average ambient over say 3 day stretches for a 5 - 10 year period. IIRC a too cold battery suffers irreversible damage, perhaps even a dead pack. So one such event for a car is one too many. My winter is no where near as cold as most of Finland but when average daily ambient goes below 15F I pay attention to the LEAF and take steps to keep the pack comfortably above 10F.
