5 バッテリー
6 保護スイッチ(保護回路)
7 保護回路
10 電圧検出手段
17 異常判定手段
20 ダミー回路(条件発生手段)
Claims (2)
- バッテリーを充電又は放電する主電源部と前記バッテリーとの間の接続ライン間に接続され、前記バッテリーの両端間に発生する電圧を分圧する電圧検出手段を備え、
前記電圧検出手段により分圧した電圧が閾値以下になる検出条件の成立から、直接前記バッテリーの異常を判断するバッテリー異常検出装置において、
前記バッテリーの充電時にこのバッテリーに異常が発生して、前記バッテリーに取り付けられた保護回路が当該バッテリーを保護するドライブ信号を出力すると、強制的に当該検出条件を成立させるために、前記電圧検出手段により分圧した電圧を閾値以下にする条件発生手段を設けたことを特徴とするバッテリー異常検出装置。 - 前記検出条件が所定時間継続して成立した場合に前記バッテリーの異常と判断する異常判定手段を設けたことを特徴とする請求項1記載のバッテリー異常検出装置。
