Abstract: Disclosed is a cooling control method and system for a battery. The cooling control method includes measuring, by a controller, an exterior temperature of a vehicle and a temperature of a battery. When the exterior temperature of the vehicle exceeds a first temperature, the method includes setting, by the controller, a cooling reference temperature based on the temperature of the battery and the exterior temperature. Furthermore, the method includes cooling, by the controller, the battery by adjusting the intensity of a cooling fan based on the set cooling reference temperature to prevent the temperature of the battery upon termination of cooling from exceeding a second temperature.
