Coolant Flow in Tesla’s Heat Pump System

From WeberAuto.

See the five modes of coolant flow in Tesla’s heat pump system. 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 onwards.
