1. A method for controlling the thermal conditioning of a rechargeable energy storage system (RESS), the method comprising:
configuring a controller with a processor and memory to receive electrical sensor data, pump sensor data, ambient temperature data, and temperature sensor data; providing to the processor, electrical sensor data indicative of a current and resistance of the RESS; calculating a heat generation value using the electrical sensor data; providing to the processor, pump sensor data indicative of an inlet temperature for the pump, outlet temperature for the pump, speed of the pump, and density of coolant within the pump; determining a mass flow rate and coolant specific heat using the pump sensor data; providing to the processor, ambient temperature data; determining a target temperature for the inlet of the pump using timestamp data, the ambient temperature, and a vehicle mode parameter; providing to the processor, temperature sensor data indicative of a measured outlet coolant temperature; calculating a required thermal power value using the target temperature, mass flow rate, coolant specific heat, and the measured outlet coolant temperature; and calculating a target thermal conditioning value for the RESS using the required thermal power value and the heat generation value wherein the target thermal conditioning value is calculated from the difference between the required thermal power value and the heat generation value to change a power demand to drive a high voltage battery heater to heat the RESS or the target thermal condition value is calculated from the accumulation of the required thermal power value and the heat generation value to change the power demand to an air conditioning compressor to cool the RESS. |
