Description
上記蓄電セルは、蓄電素子と、上記蓄電素子が封入された外装体とを備える。
上記筐体は、上記蓄電セルを収容する収容空間を有する。
上記筐体は、上記収容空間と外部空間に連通する貫通孔を有する。
上記貫通孔は、上記蓄電セルの上記蓄電素子が存在しない部分に対応する位置に形成されている。
図1は本実施形態に係る蓄電モジュール100の斜視図であり、図2は、蓄電モジュール100の分解斜視図である。これらの図に示すように蓄電モジュール100は、筐体110及び蓄電セル120を備える。なお、以下の各図において相互に直交する3方向をそれぞれX方向、Y方向及びZ方向とする。
第1板部材112及び第2板部材113には貫通孔が設けられている。図7は、貫通孔130の配置を示す模式図である。貫通孔130は第1板部材112及び第2板部材113においてそれぞれの表裏を貫通する孔である。その大きさは特に限定されないが直径数mm程度である。
異常時に蓄電セル120においてガスが発生し、内圧が上昇すると、蓄電セル120が膨張し、筐体110に応力が印加される。このような蓄電セル120を解体する場合、貫通孔130に針を挿し、外装部材122に穴を開ける。これにより、この穴からガスが排出され、筐体110に印加されている応力が消失し、安全に蓄電セル120を解体することができる。
