  • Vehicular combination chiller bypass system and method
    Patent number: 8448460
    Abstract: A chiller bypass system is provided for deployment onboard a vehicle that includes a battery pack through which a first coolant is circulated. In one embodiment, the chiller bypass system comprises a chiller, a chiller bypass duct fluidly coupled to the battery pack and configured to supply the first coolant thereto, and a chiller bypass valve. The chiller bypass valve includes: (i) a valve inlet fluidly coupled to the battery pack and configured to receive the first coolant therefrom, (ii) a first valve outlet fluidly coupled to the chiller and configured to supply the first coolant thereto, and (iii) a second valve outlet fluidly coupled to the chiller bypass duct and configured to supply the first coolant thereto. The chiller bypass valve selectively directs coolant flow between the first valve outlet and the second valve outlet to adjust the volume of the first coolant cooled by the chiller.
