It heavily depends on the electrolyte / cell chemistry. I have batteries from a Think City (made by EnerDel) and they are spec'd to operate down to an extremely low temperature of -20C. That's -4F. I don't think I'd charge them very hard at 0F but it seems that's in the temperature range to be able to do so. I know that the pack has no heater in it from the factory and people drive the things up here in Michigan. The Think factory was in Indiana. If charging the cars in winter was a problem we'd probably know it.
