Holistic thermal management heat pump system for a vehicle

Abstract:

A thermal management heat pump system and method for a vehicle, including: a cabin thermal management loop including a refrigerant loop; an energy storage system thermal management loop including a coolant loop; a power electronics thermal management loop including the coolant loop; a heat exchanger selectively coupling the refrigerant loop and the coolant loop responsive to one or more of a sensed and a commanded operating state of the vehicle; and a multi-port valve assembly selectively coupling the energy storage system thermal management loop and the power electronics thermal management loop responsive to the one or more of the sensed and the commanded operating state of the vehicle.
