Description
すなわち2番目の発明においては、所定の電圧変化量を比較的簡単な構成で定めることができる。
3番目の発明によれば、1番目の発明において、前記開閉手段の開放時において前記バッテリ電圧検出手段により検出される前記バッテリの電圧値と、前記開閉手段が開放する直前における前記開閉手段の閉鎖時において前記バッテリ電圧検出手段により検出される前記バッテリの電圧値との間の電圧変化量が所定の電圧変化量よりも大きい場合には、前記異常検出手段は前記ポンプおよび前記開閉手段のうちの少なくとも一方の異常検出を停止するようにした。
さらに、2番目の発明によれば、所定の電圧変化量を比較的簡単な構成で定めることができるという効果を奏しうる。
