POWER STORAGE MODULE AND FIXING STRUCTURE OF POWER STORAGE MODULE

摘要

A power storage module is formed by superimposing a pair of end plates at opposite ends in the stacking direction of a plurality of power storage cells that are stacked in the stacking direction. The pair of end plates are connected by a frame holding an insulator between itself and the power storage cells. Condensed water occurring on the surface of the power storage cells could contact the end plate. There is thus a possibility that a liquid junction will be formed; when the power storage module is in a mounted state the insulator includes a first rib extending in a direction, condensed water attached to the insulator cannot flow toward the end plate due to it being blocked by the first rib, thus preventing the power storage cell from forming a liquid junction with the end plate via the condensed water.

主权项

1. A power storage module comprising a plurality of power storage cells that are stacked in a stacking direction, a pair of end plates that are superimposed at opposite ends in the stacking direction of the power storage cells, a frame that is connected to the pair of end plates via fastening portions at opposite ends, and an insulating insulator that is held between the frame and the power storage cell, wherein
in a mounted state the insulator comprises a first rib that extends in a direction intersecting the stacking direction.
