Document Type and Number:
Japanese Patent JP2019186118
Kind Code:
A
Abstract:
To provide a power storage device capable of down-sizing a power storage module.SOLUTION: A power storage module 2 has a cell stack 3 formed by laminating power storage cells 8 via a positive electrode collector plate 16 and a negative electrode collector plate 17, a positive electrode bus bar 5 extending in the lamination direction of the power storage cells 8, and electrically connected with the positive electrode collector plate 16, and a negative electrode bus bar 6 extending in the lamination direction of the power storage cells 8, and electrically connected with the negative electrode collector plate 17. The positive electrode bus bar 5 has a positive electrode bending part 22 which is bent to face one end face of the cell stack 3 on one end side of the cell stack 3, the negative electrode bus bar 6 has a negative electrode bending part 24 which is bent to face the other end face of the cell stack 3 on the other end side of the cell stack 3, the positive electrode bending parts 22 of respective power storage modules 2 are connected via a positive electrode connection bus bar 28, and the negative electrode bending parts 24 of respective power storage modules 2 are connected via a negative electrode connection bus bar 29.SELECTED DRAWING: Figure 1
