To cool a plurality of battery modules of a vehicular battery pack efficiently.SOLUTION: A vehicular battery pack includes a plurality of battery modules, a cooling device which cools them and a battery case which accommodates the plurality of battery modules and the cooling device. The cooling device includes a duct assembly which passes air from a blower. A second duct of the duct assembly includes a plurality of second duct bodies which divides air passing intersection connection duct from the first duct. The plurality of battery modules include a plurality of first battery modules which are disposed in downward region of the first duct and a plurality of second battery modules which are disposed so as to shift in at least one direction among the horizontal direction with respect to the plurality of first battery modules. The first duct includes a penetration hole which penetrates a bottom wall so as to supply air to air gap between the neighboring first battery modules. The second duct bodies send air by directing to the second battery modules.SELECTED DRAWING: Figure 5

    【課題】車両用バッテリパックの複数のバッテリモジュールを効率的に冷却する。【解決手段】本発明の車両用バッテリパックは、複数のバッテリモジュールと、これらを冷却する冷却装置と、複数のバッテリモジュール及び冷却装置を収容するバッテリケースとを有し、冷却装置は、ブロワからの空気を通すダクト組立体を有し、ダクト組立体の第2ダクトは、その第1ダクトからその交差接続ダクトを通った空気を分流させる複数の第2ダクト本体を有し、複数のバッテリモジュールは、第1ダクトの下方の領域に配置される複数の第1バッテリモジュールと、複数の第1バッテリモジュールに対して水平方向のうち少なくとも1つの方向にシフトするように配置される複数の第2バッテリモジュールとを有し、第1ダクトは、隣り合う第1バッテリモジュール間の空隙に空気を供給するようにその底壁を貫通する貫通孔を有し、第2ダクト本体は第2バッテリモジュールに向けて空気を送る。【選択図】図5
