ABSTRACT:
In a battery cooling device for cooling a battery with cooling air from a cooling unit, such as a cooling fan, the cooling fan is not to be driven more than necessary. A cooling air flow control unit calculates a battery temperature change rate indicating an amount of change in battery temperature over a predetermined time based on the battery temperature, and if the calculated battery temperature change rate satisfies a predetermined suppression control condition, the cooling air flow of the cooling fan is suppressed regardless of whether or not the battery temperature is at or below a reference temperature.
