Abstract: A heat pump system, including a thermal storage medium, for use in a vehicle having a passenger compartment, and a corresponding method for providing heat to a vehicle passenger compartment. The vehicle may have an electric only vehicle mode wherein the vehicle may occupy one of an active electric drive state and an inactive state. The heat pump system may include a thermal storage medium configured to store heat produced during the inactive state. The thermal storage medium may be a device which has a thermal capacity exchangeable with a fluid medium such as an Rechargeable Energy Storage System (RESS) or a phase change material. The heat stored by the thermal storage medium during the vehicle charge event may be transmitted from the thermal storage medium to the passenger compartment via the heat pump system during the active electric drive state.

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 vehicular heat pump system utilizing intermediate gas recompression is provided. The heat pump system is for use in a vehicle having a battery and a passenger compartment. The heat pump system may include a heating circuit and a cooling circuit each including a compressor having a first inlet and a second inlet and a vapour-liquid separator configured to separate intermediate pressure refrigerant supplied by a first expansion device into refrigerant in a gaseous state flowing therethrough and refrigerant in a liquid state flowing therethrough. The vapor-liquid separator may be configured to selectively inject refrigerant in a gaseous state into the compressor at the second inlet to increase the mass flow rate of the refrigerant. This allows the heat pump system to operate effectively in cold ambient temperatures. A method of operating a heat pump system utilizing intermediate gas recompression is also provided.

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.
