Lots of ppl seem to think that the car will maintain a minimum battery temp to keep the battery from freezing when SOC is above 20%. E.g. this thread on X. Definitions of "freeze" differ, but the manual does note that you shouldn't leave the ambient temps below -30C.
Concern seems to be electrolyte freezing around -40C causing permanent damage. Presumably the coolant would freeze at some point as well.
In my part of the world, we don't really see temps below around 0F (-20C). I have yet to observe the car actively heating the battery outside of when charging or when the car is "started" (driver in the seat, brake pressed). The car seems to sleep without issue in cold temps.
So is there a lower limit at which the car will wake itself from sleep to run a battery heating cycle and prevent damage? Or is this an urban legend?
