Abstract
An exemplary method includes circulating a fluid along a fluid circuit that extends through a heat exchanger and a battery pack, and, during the circulating, heating the fluid with a flow of exhaust gas and using the fluid to heat the battery pack. An exemplary vehicle system includes a battery pack, a heat exchanger, a fluid circuit configured to circulate a fluid between the battery pack and the heat exchanger, and a valve moveable back and forth between a heating position and a cooling position. The valve in the heating position permits more flow along an exhaust circuit to heat the fluid in the fluid circuit than the valve in the cooling position.
