PROBLEM TO BE SOLVED: To suppress variation in cooling efficiency of a whole power storage device where multiple power storage units are stacked side by side.SOLUTION: In the power storage device where multiple power storage units are arranged side by side in a predetermined direction, a distribution channel for moving a heat exchange medium, used for temperature adjustment of the power storage units, in a direction orthogonal to the predetermined direction is formed between two adjoining power storage units. The distribution channel formed in the central part of the power storage device in the predetermined direction and in the central part of the power storage unit in the length direction is formed wider than the distribution channel formed at other part in the predetermined direction or in the length direction. |
