POWER STORAGE MODULE, MANUFACTURING METHOD THEREFOR, AND WORK MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a power storage module which allows for reduction in man-hour required for assembling a power storage module by stacking power storage cells.SOLUTION: A plurality of cell units are stacked. A pressurization mechanism applies a compression force in the stacking direction to the stack structure of cell units. Each cell unit has a power storage cell, and a frame for supporting the power storage cell. The frame has a positioning part for constraining the relative position of frames adjoining in the stacking direction in a direction orthogonal to the stacking direction. The positioning part positions the frames in a direction orthogonal to the stacking direction. Furthermore, in a state where a compression force is applied to the stack structure by the pressurization mechanism, a margin is left in such a direction that the frames approach furthermore.
