Description
1.発明の分野
本発明は、電気化学セルを収納するためのバッテリパックにおいて、受動的冷却機構部と、電気化学セルの肥大化により生じる外壁応力を最小限に抑制する機構部とを備えたバッテリパックハウジングを備えたバッテリパックに関する。
バッテリパックは、ポータブル電子機器から再生可能な電力システムや低公害車に至るまで、様々な技術に電力を供給する。例えばハイブリッド電気自動車(HEV)においては、燃料効率を高めるために、燃焼機関と併用してバッテリパック及び電気モータが使用されている。バッテリパックは、複数のバッテリモジュールから形成され、各バッテリモジュールは、いくつかの電気化学セルを備える。各セルは、スタック状に配置され、電気的に直列又は並列に接続される。同様にバッテリパック内のバッテリモジュールも、電気的に直列又は並列に接続される。
いくつかの態様においては、バッテリパックハウジングは、複数の電気化学セルを収容し得るように構成される。このバッテリパックハウジングは、容器を備え、この容器は、底部と、外壁と、第1の内壁と、第2の内壁とを備える。底部は、内面と、内面の反対側の外面と、内面と外面とを接合する周縁部とを備える。外壁は、周縁部を取り囲み、かつ、底部から底部の内面に垂直な方向に突出する。外壁は、第1の部分と、第1の部分に隣接する第2の部分と、第2の部分に隣接しかつ第1の部分と向かい合う第3の部分と、第2の部分と向かい合う第4の部分とを備える。第1の内壁は、第1の部分と第3の部分との間に延在し、かつ、第1の部分と第3の部分とのそれぞれに固定される。第2の内壁は、第1の部分と第3の部分との間に延在し、かつ、第1の内壁と第4の部分との間に配置される。第2の内壁は、第2の内壁と第1の内壁との間隔を変更し得るように外壁に対して可動である。
図1及び図2に示すように、バッテリパック1は、電気化学セル2を備えた発電及び電力貯蔵装置であり、各電気化学セル2は、電気的に相互に接続されかつバッテリパックハウジング40内に整えて収容される。バッテリハウジング40は、容器60及び蓋50を備え、この蓋50は、容器60の開放端部で閉鎖する。バッテリパックハウジング40内においては、セル2のアレイが、蓋50から突出するバッテリパック端子54、55に直列又は並列に電気的に接続される。蓋50と容器60とを備えたバッテリパックハウジング40は、非導電性材料から形成される。さらに、以下に詳細に説明するように、容器60は、電気化学的セルの肥大化による外壁応力を最小限に抑制する機構部に加え、受動的冷却機構部をも有する。
