  • Battery centric thermal management system utilizing a heat exchanger blending valve
    Patent number: 10522845
    Abstract: A method of regulating thermal dissipation from a vehicle battery pack is provided in which a by-pass valve is used to control the amount of battery pack coolant either passing through, or by-passing, a heat exchanger, where the coolant passing through the heat exchanger is cooled by a refrigeration system. The vehicle's HVAC system is controlled to insure that HVAC operation does not compromise maintaining the battery pack within an acceptable range of temperatures.
