Claims (7)
- 少なくとも複数の蓄電モジュールを含む複数の部材が積層されたモジュール積層体と、
密閉空間を構成し、該密閉空間内で前記モジュール積層体を積層方向に拘束する筐体と、を備え、
前記筐体は、前記密閉空間の内圧の上昇に伴って、少なくとも前記積層方向における前記モジュール積層体の拘束力が低下するように変形する、蓄電装置。 - 前記筐体は、前記モジュール積層体における前記積層方向に沿って延在する側壁を含む、請求項1に記載の蓄電装置。
- 前記モジュール積層体と前記側壁との間には、前記モジュール積層体及び前記側壁の両方に接触した中間部材が設けられている、請求項2に記載の蓄電装置。
- 前記筐体は、前記積層方向において前記側壁の両端に設けられ、前記モジュール積層体を拘束する一対の挟持部を有し、
前記積層方向において少なくとも側壁の一端に設けられた前記挟持部は、前記密閉空間の内圧の上昇に伴って、前記モジュール積層体から離間する方向に変形する、請求項2又は3に記載の蓄電装置。 - 前記側壁の前記一端に設けられた前記挟持部は、前記密閉空間の内圧の上昇前において、前記側壁の前記一端よりも前記モジュール積層体に近い位置にある押圧部であって、前記密閉空間の内圧上昇によって、前記側壁の前記一端よりも前記モジュール積層体から遠い位置に移動する前記押圧部を有する、請求項4に記載の蓄電装置。
- 前記押圧部は、前記押圧部を囲む接続部を介して前記側壁に接続されており、
前記接続部の弾性は、前記筐体の他の部分に比べて大きい、請求項5に記載の蓄電装置。 - 前記積層方向に隣り合う前記蓄電モジュール同士の間には、前記蓄電モジュール同士を互いに離間する方向に付勢する離間部材が配置されている、請求項1〜6のいずれか一項に記載の蓄電装置。
