Abstract

Provided is a power storage module in which a cell housing is less susceptible to deformation even if a power storage cell disposed in the cell housing expands. The power storage module (1) includes acell housing body (2) having a rectangular top plate (21) and bottom plate (22), and two rectangular side plates (23 and 23) disposed to face each other to connect the top plate (21) and the bottom plate (22), a plurality of cell housing spaces (27) disposed in the cell housing body (2) and separated by a partition plate (26) connecting the two side plates (23 and 23), a power storage cell (3) housed in the cell housing spaces (27), and plate-shaped flange portions (25 and 25) formed to protrude from outer surfaces of the two side plates (23 and 23), wherein the power storage module (1) is fixable to an installation site by fixing the plate-shaped flange portions (25 and 25) to the installation site.

Description

technical field [0001] The invention relates to an electric storage module. [0002] This application claims priority based on Japanese Patent Application No. 2019-128292 filed in Japan on July 10, 2019, the contents of which are incorporated herein by reference. Background technique [0003] The power storage module is installed in hybrid vehicles, electric vehicles, and the like. The power storage module is formed by stacking a plurality of power storage cells. The electric storage unit includes a battery element composed of a positive electrode and a negative electrode. [0004] For example, Patent Document 1 describes an electric storage module comprising: a battery pack formed by stacking a plurality of batteries; end plates provided at both ends in the stacking direction of the battery pack; and connecting belts connecting the end plates to each other. The fastening member receiving part is located on the inner side of the connecting belt and is in direct contact wi...
