Abstract

A battery thermal management system includes a passenger cabin air-conditioning refrigerant loop including at least one evaporator in fluid communication with a chiller and a battery pack coolant loop in fluid communication with the chiller. A controller is configured to determine whether a temperature of the at least one evaporator falls within a predetermined temperature range, and if so to cause a valve to bypass a refrigerant from the air-conditioning refrigerant loop to the chiller. Evaporator temperature is determined by providing at least one evaporator temperature sensor.
