A cold ambient battery chilling mode of an electric vehicle may be implemented if the vehicle battery is being charged when the ambient air temperature is low and a temperature of the battery is elevated. During cold ambient charging, coolant flows through a heater core and through a battery heat exchanger. Cold ambient air may be utilized to cool the coolant flowing through the heater core, and coolant from the heater core flows through the battery heat exchanger and cools the battery during charging. A battery chiller may be deactivated when the cold ambient battery chilling mode is activated to reduce energy consumption.
