Abstract: A vehicle includes a thermal energy management system with first and second thermal fluid loops. The first thermal fluid loop includes a coolant pump configured to circulate a coolant through a vehicle battery and a chiller. The second thermal fluid loop is configured to circulate a refrigerant through the chiller, a compressor, and at least one condenser. The controller is configured to control the thermal energy management system according to a passenger compartment cooling mode and a battery cooling mode. In the passenger compartment cooling mode the compressor is operated at a first power setting. In the battery cooling mode the compressor is operated at a second power setting and the chiller is controlled to transfer thermal energy from the first thermal fluid loop to the second fluid thermal loop. The second power setting is less than the first power setting.

Abstract: A thermal management method and system in a vehicle include a chiller to cause heat transfer between a coolant loop that defines a path in which a coolant circulates and a refrigerant loop that defines a path in which a refrigerant circulates. The system includes an electronic expansion valve (EXV) in the refrigerant loop to control a flow of the refrigerant into a first part of the chiller, and a coolant pump in the coolant loop to control a flow of the coolant into a second part of the chiller. A controller controls the EXV and the coolant pump based on a target amount for the heat transfer.

Abstract: A thermal energy management system for a vehicle supplies thermal energy to a passenger compartment of the vehicle. The thermal energy management system includes three thermal fluid loops. The first thermal fluid loop includes a coolant pump for circulating a coolant through at least a vehicle battery, a transmission oil cooler of the vehicle, and a chiller such that the coolant selectively transfers thermal energy from the vehicle battery, the transmission oil cooler, and the chiller. The second thermal fluid loop circulates oil through the transmission oil cooler. The third thermal fluid loop circulates a refrigerant through at least the chiller and at least one condenser such that the third thermal fluid loop transfers thermal energy to the passenger compartment.

Abstract: A thermal management system for a vehicle includes a plurality of fluid flow circuits including a heating ventilation and air conditioning (HVAC) circuit circulating a flow of refrigerant therethrough and including an evaporator, a chiller heat exchanger, a first expansion valve located upstream of the evaporator, a second expansion valve located upstream of the chiller heat exchanger, and a heat exchanger located fluidly upstream of the expansion valves. A propulsion cooling circuit circulates a flow of coolant therethrough which is utilized to condition one or more propulsion components of the vehicle. The flow of coolant is directed through the heat exchanger, thus subcooling the flow of refrigerant. A controller is operably connected to one or more control points of the thermal management system and is configured to adjust the one or more control points to achieve a target amount of subcooling of the flow of refrigerant at the heat exchanger.

Abstract: A system and method for managing thermal energy of a vehicle having a battery and an electric propulsion system are provided. The system monitors a current battery temperature, calculates an actual average battery temperature, and compares the calculated actual average battery temperature to a target lifetime battery temperature. If the actual average battery temperature is greater than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system cools the battery to below the current battery temperature. However, if the actual average battery temperature is less than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system delays cooling the battery. Therefore, the system may avoid expending energy to cool the battery in certain conditions.

Abstract: A thermal management system includes a coolant pump, high-voltage electric heater (HEH) for heating the coolant, a heater core, a blower directing air to the heater core, a cabin heater valve (CHV), sensors, and a controller. The CHV has an Engine Bypass position blocking coolant flow from the HEH into the engine, and an Engine Link position directing coolant from the HEH into the engine. In a method, the sensors measure engine outlet coolant temperature (ECT), inlet coolant temperature (ICT) to the HEH, inlet air temperature into the heater core, and outlet air temperature from the heater core. The controller calculates a target coolant temperature (TCT) value as a function of the air temperatures and mass flow rates, and controls the CHV via position control signals such that the CHV is switched between the Engine Link position and the Engine Bypass position when ICT equals the calculated TCT value.
