摘要
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. The battery is actively cooled by circulating coolant from the battery to a chiller of an air conditioning system when a battery temperature is above a predetermined power-limiting temperature. The battery is passively cooled by circulating coolant from the battery to a radiator when the battery temperature is between a first threshold and the power-limiting temperature and a difference between a battery coolant temperature and an ambient air temperature is greater than a predetermined difference. The battery is actively cooled using the chiller when the battery temperature is between the first threshold and the power-limiting temperature and the difference between the battery coolant temperature and the ambient air temperature is less than the predetermined difference.
