A battery cooling apparatus includes a case for housing battery cells and a fan device disposed in the case for blowing air through a circulation passage to cool the battery cells. The case includes a discharge passage which makes communication between inside and outside of the case to allow part of the air circulating through the circulation passage to leak to outside the case. The fan device includes a first inflow passage and a second inflow passage. The first inflow passage, which is part of the circulation passage, is provided to allow the air having cooled the battery cells to be sucked into the fan device. The second inflow passage makes communication between the outside of the case and the fan device to allow air outside the case to be sucked into the circulation passage by suction force of the fan device.
