Abstract: A thermal management system for a battery pack having a conductive cooling plate and battery cells includes a compressor, flow control valves, temperature sensor(s), and a controller. The compressor circulates refrigerant through the plate to cool the cells. The temperature sensor measures a temperature of the battery pack. The controller is programmed to receive the temperature from the temperature sensors and selectively transmit switching control signals to the valves to command a change in direction or flow of the refrigerant through the cooling plate. This limits a temperature variance between the battery cells over time. A vehicle includes a transmission, an electric traction motor, a battery pack, and the thermal management system noted above. A method includes receiving the temperature, transmitting switching control signals to the valves, and controlling a flow of refrigerant through the plate via the valves in response to the switching control signals.

Abstract: A thermal management system for a vehicle and a method for controlling the same are provided. The thermal management system comprises a first coolant circuit, a second coolant circuit, a refrigerant circuit, and a controller. The first coolant circuit includes at least a first coolant circuit heat exchanger, a Coolant Heater Control Module (CHCM), a CHCM mixing valve, and a bypass valve. The CHCM mixing valve is configured to modulate flow of a coolant between the first coolant circuit heat exchanger and the CHCM. The bypass valve is configured to link the first coolant circuit with the engine. The controller directs the thermal management system to operate in one of a high efficiency mode, a heat pump assist mode, a maximum performance mode, and a propulsion system energy improvement mode, effectuating the selected mode of operation via the actuation of the CHCM valve and the bypass valve to predetermined positions.

Abstract: A thermal management system having a first heating device, such as a rechargeable energy storage system (RESS), and a second heating device, such as an internal combustion engine (ICE), for a vehicle is provided. The system may allow waste heat within an ICE to be stored in a RESS, and may cool the RESS by depositing heat in the ICE. The RESS and the ICE are located in a first coolant circuit and a second coolant circuit, respectively. The system also includes a third coolant circuit interconnected with the first coolant circuit, and in thermal communication with the second coolant circuit via a first heat exchanger. The first and third coolant circuits are configured to circulate a first coolant, and the second coolant circuit is configured to circulate a second coolant. The RESS and the ICE are each configured to selectively operate as a heat source or a heat sink.

Abstract: A vehicular heat pump system may have two inside heat exchangers within an HVAC module, and may operate in mild cooling and mild heating modes. In mild cooling mode, a first isolation valve and a second isolation valve are fully open and closed, respectively, to direct the refrigerant flow to the first inside heat exchanger only. In mild heating mode, the first isolation valve and the second isolation valve are fully closed and fully open, respectively, to direct the refrigerant flow to the second inside heat exchanger only. In both modes, a first metering device is partially open to control the flow and expansion of the refrigerant, and a second metering device is fully closed to prevent the refrigerant from flowing between the inside heat exchangers. This staged operation of the heat pump system may reduce the risk of flash fog as well as reduce discharge air temperature spreads.
