A system for cooling a battery. The system has a cabin cooling refrigerant pathway including an orifice tube through which refrigerant flows to an evaporator. A battery cooling refrigerant pathway includes a thermal expansion valve (TXV) through which refrigerant flows to a chiller. An accumulator is in receipt of refrigerant from both the cabin cooling refrigerant pathway and the battery cooling refrigerant pathway. A battery coolant loop includes a coolant pathway for directing coolant from the chiller to the battery to cool the battery. The coolant is cooled by the chiller.
