Patent ID: 8215432

Claim:
A vehicle comprising: a power plant; a radiator configured to cool the power plant; a cooling fan located adjacent to the radiator and configured to draw air through the radiator; an air conditioning system; a battery pack; and a battery thermal system including a battery radiator located adjacent to the radiator and in fluid communication with the battery pack; a battery coolant heater located upstream of the battery pack and configured to receive a flow of a liquid coolant therethrough, whereby the battery coolant heater is activatable to heat the coolant flowing therethrough; and an electric pump for pumping the liquid coolant through the battery pack, the battery radiator, and the battery coolant heater; and wherein the battery thermal system includes a refrigerant-to-coolant heat exchanger configured to selectively receive a refrigerant from the air conditioning system, and a valve configured to receive the liquid coolant from the battery pack and selectively redirect the liquid coolant to one of the refrigerant-to-coolant heat exchanger and the battery radiator.
