To provide a power storage device for a railway vehicle, formed in a small size and having high reliability, and provide a cooling method of the power storage device in the railway vehicle.SOLUTION: Each of power storage devices 1, 1B, 1C, 1D, 1E, 1F, and 1G mounted onto a railway vehicle 2, includes: a power battery (a module 11); a circulation fan 12; a housing 1c housing and sealing the power battery (the module 11) and the circulation fan 12. The housing 1c includes a wind-receiving surface (at least any one of a device side surface 21, a device bottom surface 22, and a device ceiling surface 23) to which a traveling wind 3 generated in accordance with the traveling of the railway vehicle 2 is exposed. The circulation fan 12 circulates an air in the housing 1c in a circulation path 51 containing an inner wall surface of the housing 1c against a short direction S of the housing 1c of any one of the traveling direction of the railway vehicle 2 and an orthogonal direction to the traveling direction and the wind-receiving surface.SELECTED DRAWING: Figure 3
【課題】小型で信頼性の高い鉄道車両用の蓄電装置及び鉄道車両における蓄電装置の冷却方法を提供する。【解決手段】鉄道車両2に搭載される蓄電装置1,1B,1C,1D,1E,1F,1Gは、蓄電池(モジュール11)と、循環ファン12と、蓄電池(モジュール11)及び循環ファン12を収容して密閉する筐体1cと、を有する。筐体1cは、鉄道車両2の走行に伴って発生する走行風3が当たる受風面(装置側面21、装置底面22、装置天井面23の何れか少なくとも一つ)を有する。循環ファン12は、筐体1c内の空気を、鉄道車両2の走行方向及び走行方向に対する直交方向の何れかである筐体1cの短手方向Sかつ受風面に対する筐体1cの内壁面を含む循環経路51で循環させる。【選択図】図3
