Not really. New BMW’s don’t actually have a condenser anymore. There are two separate cooling circuits, high temp for engine and trans, then a low temp circuit for A/C and intake manifold (air/water intercooler) both with their own pumps (both electric and mechanical) and rads. So the refrigerant actually has a small refrigerant to water cooler.
Batteries use antifreeze-based coolant with hoses similar in size to a heater core to transfer heat in and out of the pack via both the radiator and AC or heat pump as needed. Despite that most EV's battery packs are installed permanently, they typically use quick disconnects on those coolant hoses.
There is zero coolant going to the battery packs on BMW. There are refrigerant lines only.
Interesting.....sounds like a good idea. Would probably do a better job of cooling battery under high load too.
And no electrically conductive coolant in the battery pack.
