See the five different modes of coolant flow in Tesla’s heat pump system through the Service Mode displayed on the car’s screen. Learn about how coolant is utilized in transferring heat energy to and from various powertrain and high-voltage battery components during cabin heating or cooling.

This same process is also applied to powertrain and high-voltage battery heating and cooling. This heat pump technology is integrated into Tesla Models S, 3, X, and Y from 2021 and onward.
