Abstract

See full text

A multi-mode thermal management system is provided for use with the battery pack of an electric vehicle, the system utilizing the surface area of the battery pack to remove battery pack heat. The system includes two sets of coolant conduits separated by a thermal insulator, with one set of the coolant conduits thermally coupled to the batteries and the other set of coolant conduits coupled to at least one thermally conductive battery pack surface. A valve controller is used to optimize system performance by coupling the battery cooling conduits to the battery pack heat withdrawal conduits and/or a separate radiator and/or a heat exchanger coupled to a refrigeration subsystem.
