Frozen Tesla Model 3 Battery - Testing Supercharger Charging in Freezing Cold Weather

TLDRIn this video, we test how a Tesla Model 3 battery performs in freezing cold weather. We deep freeze the car at a supercharger and observe the charging process. The battery heater activates before accepting a charge, and it takes around half an hour for the battery to start charging. On-route battery preconditioning is crucial in cold weather to ensure efficient charging.
