A battery cooling apparatus for positively cooling an in-vehicle battery is disclosed. Air that has passed through a cooler ( 5 ) is supplied to batteries ( 1 ), and only internal air, but not external air, passes through the cooler ( 5 ). In this way, the batteries ( 1 ) can be cooled without being greatly affected by the disturbances such as the heat of an exhaust pipe and sunlight. Thus, the batteries ( 1 ) can be sufficiently cooled without increasing the heat radiation area, i.e. the surface area of the batteries ( 1 ). Noise of cooling air flow can be reduced while at the same time suppressing increases in both size and production cost of the battery.
