へ導入され、後側の空気排出部７より排出される。According to the structure of the above embodiment, when the vehicle is traveling, the outside air flows into the compartment 11 from the battery outside air introduction port 14 as traveling dynamic wind, and the pushing air pressure causes the outside air to be introduced through the air duct 9. It is introduced from the portion 6 into the storage portion of the battery 3 and is discharged from the rear air discharge portion 7.
【００２０】この結果、バッテリ３を外気で冷却できる
と共に、バッテリ３から発生するＨ2 ガスは、排出空気
と共に外部へ排出される。As a result, the battery 3 can be cooled by the outside air, and the H 2 gas generated from the battery 3 is discharged to the outside together with the discharge air.
【００２１】このように、車両走行中は走行動風が得ら
れるため、空気排出部７のファン８は低回転で済み、電
力消費を少なくすることができると共に、ファン騒音を
小さくすることができる。As described above, since the moving wind can be obtained while the vehicle is traveling, the fan 8 of the air discharging portion 7 can be rotated at a low speed, which can reduce power consumption and fan noise. .

することは全くなく、安全性を高めることができる。Further, since the communication portion is formed in the compartment and the outside air is taken in from the outside air introduction port for the battery which is different from the outside air introduction port for the air conditioning, the air conditioner is operated while parked or parked. However, since the H 2 gas generated from the battery is directed upward from the battery storage section to the compartment and is discharged to the outside from the outside air inlet for the battery, it is never sucked into the vehicle interior, which is a safety measure. Can be increased.
