PROBLEM TO BE SOLVED: To provide a battery cooling mechanism by which storage batteries of a power storage device can be cooled efficiently and uniformly.SOLUTION: A battery cooling mechanism comprises: at least one group constituted by a plurality of battery modules 3, provided that in the at least one group, at least one battery module is disposed in an upstream space located on an upstream side in a flow direction of a cooling air, a downstream space located on a downstream side of a case 2, and a midstream space located between the upstream space and the downstream space; a duct 13 having a first outlet 13b for expelling a cooling air toward upstream of the upstream space, and a second outlet 13c provided at a boundary of the upstream space and the midstream space for expelling a cooling air toward upstream of the midstream space; a first air guide mechanism 51 for the cooling air expelled from the first outlet and passed through the upstream space to bypass the midstream space; and a second air guide mechanism 52 for leading the cooling air thus bypassed to pass through the downstream space.SELECTED DRAWING: Figure 1

    【課題】蓄電装置の各蓄電池を効率よく、均等に冷却することが可能な電池冷却機構を提供する。【解決手段】複数の電池モジュール3により少なくとも1つのグループが構成され、グループのうち冷却風の流れ方向の上流側に位置する上流空間と、ケース2の下流側に位置する下流空間と、上流空間と下流空間の間に位置する中流空間とに電池モジュールが少なくとも1つずつ配置される。ダクト13は、上流空間よりも上流側に冷却風を吹き出す第1吹出口13bと、上流空間と中流空間の境界に設けられ、中流空間よりも上流側に冷却風を吹き出す第2吹出口13cとを有する。第1吹出口から吹き出され、上流空間を通過した冷却風を中流空間に対して迂回させる第1導風機構51と、迂回させた冷却風を下流空間を通過するように導く第2導風機構52とを備える。【選択図】 図1
