Cooling of a battery pack of an electrified vehicle is performed with an optimized energy usage and with minimal impact on cooling of the passenger cabin. Refrigerant from a condenser in an air conditioning system is evaporated in a front evaporator to cool a main air flow in a front cabin zone. The refrigerant is evaporated in a coolant chiller to cool a liquid coolant. The liquid coolant is pumped from the chiller to a rear exchanger to cool a rear air flow in a rear cabin zone. The liquid coolant is pumped from the chiller to the battery when a battery temperature and an ambient air temperature correspond to an active cooling mode. The coolant is pumped between the battery and a passive radiator instead of the chiller when the battery coolant temperature and the ambient air temperature correspond to a passive cooling mode.
