Electric vehicles require some extra care when you have to driving in winter, but some owners like to push them to the limit to see what can happen. This is the case of Kyle Conner from the channel Youtube Out of Spec Reviews who after taking his Tesla Model 3 outside and leaving it frozen decided to plug it into a supercharger to test the battery.
Charging an electric vehicle in freezing temperatures is known to require extra care compared to charging during the summer. Of course, the most important is the battery preconditioningthat is, heating the battery to an operating temperature that is optimal for charging.
But, there are other things EV owners can do to help the battery charge faster, like parking the vehicle in a garage whenever possible, keeping it plugged in when parked, or never letting the state of charge of the EV battery is too low, among other things.
Frozen Tesla Model 3 plugged into a supercharger
Well, Kyle decided to leave his Tesla in the freezing cold overnight at a Supercharger station in Loveland, Colorado for two straight days. After that, she went back to the car and connected it to a Supercharger, without any preparation, despite the fact that outside it was -14° Fahrenheit (-26° Celsius).
The result was that after about 45 minutes After connecting the Tesla to the supercharger, no power had reached the battery pack. This is because the system used the electricity supplied by the charger to first heat the battery.

It should be noted that the battery had a 35% state of charge when Kyle first plugged it in and set the charge limit to a 90% SoC. Battery it took about an hour and a half on reaching 90%, which is a long time to wait for your EV to charge, especially in extremely cold conditions.
However, it’s not too bad if you subtract the initial 45 minutes dedicated exclusively to warming up the battery and especially considering the outside temperature during the charging session.
As Kyle indicates at the beginning of the video, this was a experiment intended to show how one behaves frozen battery in extreme cold conditions. This is relevant to Tesla owners who don’t have a charger at home or in a garage, and rely on the Supercharger network for charging.
Other Tesla owners have ways to avoid reaching a point where their battery freezes, from charging their EVs overnight in the garage to using the Navigate to Supercharger feature during a long drive, which automatically heats the battery. battery on the way to the charging station.
