POWER STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power storage device capable of suppressing variation in temperature of each power storage element.SOLUTION: A power storage device comprises: a plurality of power storage elements arranged in a first direction; and a plurality of spacers each arranged adjacently to the power storage elements in the first direction. Each of the plurality of spacers has an air channel formation part that forms a ventilation flue together with the adjacent power storage elements in the first direction. Each of the power storage elements arranged at both ends in the first direction is likely to be cooled down compared with each of the power storage elements arranged between both ends in the first direction.SELECTED DRAWING: Figure 9
