Abstract
Description
電気化学的な蓄電用の電池はしばしば、露出すると人や物を危険にさらす可能性がある攻撃性の物質を含むことが多い。エネルギー蓄積器の中には、そのような危険の他にさらに、使用される電解質が可燃性であるため火災や爆発の危険もある電池もあり、たとえばリチウムイオン(「Liイオン」)電池ではそのような危険がある。それゆえ公知の電池やキャパシタは、予測される機械的負荷にも、電池の被覆部が損傷することなく電池やキャパシタが耐え、危険物質がエネルギー蓄積器の周辺に流出するのを防止するように構成される。
電池やキャパシタ等であるエネルギー蓄積器やエネルギー蓄積器の電解質の火災や爆発の危険性は、エネルギー蓄積器の充電状態に依存する。テストを行った結果、電解質が露出したときのエネルギー蓄積器の充電状態の低下の割合が小さいと、変形しても火災または爆発による損傷を回避できる場合が多いことが判明した。
図1に、保護装置100をブロック回路図で示す。処理装置110がセンサ120に接続されている。前記処理装置110は有利には、マイクロコンピュータの形態の電子処理装置とされるが、ハードワイヤードロジックとして構成することもできる。
