AI Technical Summary
In existing battery packs, heat generation is promoted when air comes into contact with gas generated from a battery cell, leading to potential overheating issues.
A power storage device with multiple modules arranged in a line, featuring a case with a pressure relief valve and a breathing membrane, where the distance between the breathing membrane and the pressure relief valve is shorter than the distance between the exhaust port and the pressure relief valve, thereby controlling gas flow and reducing heat generation.
This configuration suppresses the promotion of heat generation within the case by minimizing the movement of air and reducing blast generation, thus enhancing safety and performance.
