How Does Tesla Air Conditioning Work?

Tesla air conditioning works by utilizing an AC system powered by electricity.

Similar to a domestic refrigerator compressor, the AC compressor in Tesla cars operates on 400 volts and is located at the front of the vehicle.

It draws power from the car’s battery pack or Energy Storage System (ESS).

The compressor pushes refrigerant through a chilling unit, cooling the air before it reaches the AC vent.

Additionally, Tesla uses an electric heater instead of a heater matrix found in internal combustion engine-powered cars.

To prevent draining too much power from the ESS, Tesla employs a positive temperature coefficient (PTC) heater, which increases its electrical resistance with increasing heat.
