I've got a surprise by reading the Model S user manual (Page 25) : «Do not expose Model S to ambiant temperatures above 140° F (60°C) or below -22°F (-30°C) for more than 24 hours at a time.» This warning really surprises me for the cold part, because in Canada (places like Edmonton, Northern Quebec, Norther Ontario) we get temperatures below -30°C for more than 24 consecutive hours EVERY year !! And also, I thought that cold was GOOD for long time battery life !! At least I thought that by plugging the car, that would be no issue, no? That what the liquid cooling system is for, right, keeping the battery pack at optimum operating temperature? Does it mean that people living in Northern parts of Canada must have a heated garage to own a Model S ?? Mods: I couldn't find threads discussions about this subject, feel free to correct if it's the case.
