Do we know for sure that the ID.4 battery doesn’t have its own heating/cooling system? And if not, the A/C is acting as a heat pump to warm the battery? It would seem that isn’t the case for vehicles without the heat pump, and that a resistive heater in the battery is more likely. Not sure.Yes, the generous AC unit under the front hood takes care of battery heating and cooling, as well as cabin AC duty.
I think the VW person might have misunderstood the question. From a Jalopnik article on the MEB platform (The Fascinating Engineering Behind VW's Electric Car Platform of the Future (jalopnik.com) :I did a little digging for more info and VW sent me this email:
"..I've reviewed with our EV Guide team and as promised, I'm following up with information about our thermal system in the ID.4. I'm able to confirm that it does not have an active thermal control system in that it does not cool differently depending on whether it is summer or winter".
Have a good rest of your day and stay safe!

I think the VW person might have misunderstood the question. From a Jalopnik article on the MEB platform (The Fascinating Engineering Behind VW's Electric Car Platform of the Future (jalopnik.com) :
"The motor unit and battery pack are both liquid cooled, with the latter in a low temperature loop that includes a chiller (a refrigerant-to-coolant heat exchanger that allows for additional cooling beyond what a passive water-to-air radiator at the front of a typical automobile could offer) and the former in a high-temp loop.....
Seems like a pretty good system that is robust. And maybe something more going on than they have released
