A battery assembly system used for an electric vehicle having a configuration in which electrolyte is not released from an exhaust passage even if the electrolyte is released in a mist state from a cell. A battery assembly case is provided behind a rear seat in a cabin. An exhaust duct having a cooling fan is connected to the battery assembly case, and an air inlet port is provided to the battery assembly case at the side opposite to the portion where the exhaust duct is connected. As the cooling fan, a sirocco fan or an axial-flow fan is used. The air for forcibly cooling the battery assembly is allowed to flow in the cabin, the air inlet port, the battery assembly case, the exhaust duct, the cooling fan, and the exhaust duct in this order. A mist state electrolyte released from the cell together with the air is allowed to collide with and is attached to a cascade of the fan or the wall surface of the fan.
