Heat pump systems are super efficient compared to most other heating systems such as electric resistance heating. The coefficient of performance of heat pumps is usually 2~3 while that of electric resistance heating is 1. In the era of electric vehicle, the goal of vehicle thermal management is not only keeping the cabin at suitable temperature, but also taking care of the battery temperature. Battery performance degrades significantly at low temperature, while there is no waste heat from the engine available for heating in a full electric vehicle. Heating by electric resistance heating can drain the battery quickly ...
