How does the gen5 prime/phev manage traction battery temperature while charging in warm conditions? I know the gen5 hybrid has a fan (with a filter) that circulates cabin air through the battery to cool the traction battery while charging. But the phev lacks this fan and filter. l have read that the car uses coolant lines to manage battery heat. OK, but does that mean that the air conditioner or heat pump starts up on its own while the car is off (but plugged in and charging) to cool and circulate coolant through the battery cooling system?
Actually, there are options to disable heating and/or cooling while charging, so you're free to stop it using power for temperature control. But then it would need to slow or stop charging while the battery wasn't at a good temperature.
