Description
次に、本発明に係る第2実施形態について説明する。本実施形態の組電池100は、単電池10が横向きに配置されている点、正極タブ62が弾性変形している点において、実施形態1の構成と異なる。その他の構成は、基本的には実施形態1の構成と同じであるため、詳細な説明を省略する。図5は、図3に対応しており、組電池の断面図である。図6は、正極タブ62の溶接方法を模式的に示している。
本実施形態2では、単電池10を横向きに配置したが、実施形態1と同様に単電池10を縦向きに配置してもよい。この場合、単電池10は、重力及び正極タブ62の弾性力双方の力を用いてヒューズ64から離隔する方向に引っ張られるため、負極端子12及びヒューズ64の再導通をより確実に防止することができる。
上述の実施形態1及び2では、単電池10の外面に接触する絶縁体30を熱溶融、或いは熱分解させることにより、保持力を低下させたが、本発明はこれに限るものではなく、ヒューズ64の溶断時に単電池10に対する保持力を低下させる他の手段を用いることもできる。ここで、当該他の手段は、例えば、圧電素子を用いて保持力を電気的に制御する方法、或いは膨張容器を用いて保持力を制御する方法であってもよい。圧電素子は電圧の印加に応じて厚みを変化させる機能を有しているため、例えば、絶縁体30と散熱板20との間に圧電素子を介在させ、圧電素子に対する電圧の印加を制御することによって、絶縁体30による保持力を制御することができる。また、絶縁体30と散熱板20との間に膨張容器を介在させ、膨張容器の体積を変化させることにより、絶縁体30による保持力を制御することができる。
