Thankfully, I've had no need to research what protections the car might employ to keep the traction battery from freezing in the conditions you mentioned, but I'm 99% sure there would be none of them implemented if the 12 volt battery is disconnected - Without 12 volts present, everything in the car is effectively 'dead' - It's temperature sensing circuitry needs 12 volts to functionI stored one of our cars for about 10 months with the traction battery at about 35%, occasionally starting it, but never in the conditions you're talking about. When it came time to drive the car again, I had to first replace the 12 volt battery. If I had it to do again, I would leave a trickle charger connected to it 24/7, but . . . . if I was leaving it outside in -25C temperatures, I would bring the 12 volt battery inside - It's a standard lead acid battery and I think it might freeze, even with a trickle charger on itDon
