Abstract:
1. A method of operating a thermal management system of a vehicle having an electric traction motor, the method comprising: circulating coolant through a first thermal load; circulating refrigerant through a refrigerant circuit including a condenser and a compressor to cool at least one second thermal load; receiving signals from a sensor that are indicative of a temperature of the first thermal load; determining if a threshold temperature is exceeded based on the signals received from the sensor; substantially preventing the outlet pressure of the compressor from exceeding a second maximum outlet threshold pressure if the threshold temperature is determined not to be exceeded; and substantially preventing the outlet pressure of the compressor from exceeding a second maximum outlet threshold pressure if the threshold temperature is determined to be exceed, wherein the second maximum outlet threshold pressure is lower than the first maximum outlet threshold pressure.
