A man decided to deep-freeze his Tesla Model 3 in Colorado snow for two days, then plugged it into a Supercharger with interesting results.
The 2019 Model 3 Performance was left outside in the Colorado cold for 48 hours not plugged into anything at all.
Temperatures dropped as low as minus 14 degrees Fahrenheit as the car turned into a frozen brick.
Then, he plugged the EV straight into a Supercharger to see how the battery would react, and he was surprised by the results.

One deep-frozen Tesla Model 3, please
EV reviewer Kyle Conner from Out of Spec Reviews on YouTube parked his Model 3 beside a freezing Colorado Supercharger and left it untouched for two full days.
When he returned, the car’s display showed minus nine degrees Fahrenheit, with The Weather Channel reading -14.
Even getting the charging cable to plug in was a struggle, with the first supercharger being entirely frozen over.
When he finally plugged the car in, it produced five kilowatts, but none of that was going into the battery – it was all being used to heat the pack from the inside using waste heat from both motors.
For the first half hour, the charging level didn’t rise at all.
The system focused solely on warming the cold battery; about four kilowatt hours of energy were burned just to bring the pack to a temperature where charging could begin.
Could the supercharger survive the deep-freeze?
After roughly 30 minutes, the Tesla suddenly showed a 23-kilowatt charge rate.
Once the battery warmed enough, charging became a normal curve, eventually reaching around 150 kilowatts despite ambient temperatures dropping to -16 Fahrenheit.
Within about an hour and fifteen minutes, the car reached 70 percent state of charge and continued to behave like a normal Model 3.
By the time it hit 90 percent, the snowflake icon had disappeared, indicating the entire battery was properly warmed.
In the end, the Model 3 handled the brutal experiment with no issue, it just needed defrosting time.
