Let's Look At Energy Consumption Of Tesla Model 3 Heater

Tesla Model 3 takes several kW for heating...if needed.

Tech Forum checked out how much energy a Tesla Model 3 would need to heat the cabin at 52°F (11.1 °C) with general heating maxed, while the driver's seat heater is set for a single bar.

The car was connected to the grid, but charging was scheduled for a later time, which enabled us to see how much out of the available 32 amps the Tesla took for heating purposes.


What do you think?

As it turns out, it took around 4,800 W - around 20 A at 240 V (although at the beginning of the video it was even higher by 1-2 kW, up to 27 A).

When the general heating was off, the driver's seat heater (set at one bar) used roughly 500 W (2 A at 240 V). That would mean general heating needed over 4,300 W.
