Cooling the Hybrid Module

Cooling the hybrid module

The hybrid module is integrated in the high-temperature circuit of the engine so that heat can be dissipated. When the combustion engine is switched off, an electric auxiliary water pump ensures continued circulation of the coolant.

The hybrid module can be decoupled from the cooling system via a vacuum-controlled rotary disc valve so that the combustion engine heats up more quickly. Sensors measure the temperature in the hybrid module and transmit the value to the control unit in the power electronics.
