that's what the model 3 does. it induces resistance in the motor at 0 rpm to generate heat which is then transferred to the coolant loop to heat the battery.

but in order to warm up the very large battery pack, on a cold morning you need to turn the car on (well) before you start driving to have it warm enough for full regen.

You can, of course, do this from the Tesla app. It’s not like an ICE car where (usually) you have to physically be in it to start it.
