My Fluence lives in a garage without mains power. To charge the 12v, I bought one of these Allpowers power banks to connect to a 12v charger.
I usually connect up, then bring the power bank home the following week. It's really cold today, and I just collected the thing and put it on charge. The display showed it refused to charge, until it had sat here for several hours. I guess the batteries must have been below freezing.
Presumably, the same would happen to an EV traction battery if it was left in the cold, long enough, wouldn't it?
