I think this is a completely different scenario. In the hypothetical desert scenario, the vehicle operator *chooses* to run the A/C; in the parking an EV on a cold night without plugging it in, the *vehicle* chooses to run some additional parasitic load without the operator's knowledge. I further think it is completely reasonable to assume that the operator will not know that the battery will lose (significant) energy trying to warm itself overnight. When you park your vehicle and turn it off for the night, ICE or EV, it is (or should be) a reasonable assumption that when you return and turn it back on it will have the same amount of "fuel" onboard. I think that rather than heating the pack all night trying to keep it warm enough to charge (if indeed that is what happened), it would be a smarter decision for the vehicle to leave the pack cool to minimum operating temp, and if later plugged in to charge, then use shore power to heat the pack to minimum charging temperature prior to allowing charging to begin.
