Battery cooling air discharge structure
A battery cooling air discharge structure is configured to suppress noise of the cooling air for a battery. The battery cooling air discharge structure includes a floor panel, a floor, a plurality of rows of seats and an exhaust duct. The floor panel bottom forms a lower part of a vehicle body of a vehicle and enables placement of a battery. The floor panel top portion is arranged above the floor panel to allow placement of the battery between the floor panel top portion and the floor panel. The seats are arranged on the floor. The exhaust duct discharges battery cooling air. The exhaust duct has an exhaust port located between the floor and a seating part of a rear seat that constitutes the seats. An underside of the seating part has a notch. At least an area of the exhaust port is located adjacent to the notch.
