  • Patent number: 11807074
    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.

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.

  • Patent number: 11152653
    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.

  • Patent number: 10953726
    Abstract: A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.

  • Patent number: 10005339
    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.
