Abstract
A vehicle includes a traction battery and a cooling system. The cooling system has a chiller, a radiator, and conduit and valving arranged to form a thermal circuit configured to selectively transport heat via coolant from the traction battery to the radiator. The vehicle also includes a grille shutter assembly having an opening and shutters movable to alter an effective cross-sectional area of the opening. A controller is programed to operate the shutters to change the effective cross-sectional area of the opening to increase or decrease air flow over the radiator based on a temperature of the coolant and an ambient air temperature.
