Description
図1は、本実施形態における電池電圧検出装置1の構成概略図である。この図1に示すように、電池電圧検出装置1は、直列接続されたN個の電池セルB1〜BNの各セル電圧を検出するECU(Electronic Control Unit)であり、電池セルB1〜BNの各々に個別に設けられたセル電圧検出回路D1〜DNと、レギュレータ(基準電源回路)RGと、コンパレータ(電源電圧監視回路)CMと、マイコン(電圧処理部)Mとを備えている。
なお、他のセル電圧検出回路の回路構成については、上述したn番目のセル電圧検出回路Dnと同様である(nに当てはめる数字を代えれば良い)ので説明を省略する。
図2は、マイコンMが実行するセル電圧検出処理を表すフローチャートである。マイコンMは、この図2に示すセル電圧検出処理を一定周期で繰り返し実行することにより、各電池セルB1〜BNのセル電圧検出データを収集する。
Claims (1)
- 電池セルのセル電圧を検出する電圧検出回路と、該電圧検出回路の出力電圧をA/D変換してセル電圧検出データを収集するセル電圧検出処理を一定周期で繰り返し実行する電圧処理部とを備えた電池電圧検出装置であって、
外部供給電源電圧を降圧して基準電源電圧を生成する基準電源回路と、
前記外部供給電源電圧と前記基準電源電圧とを比較し、前記外部供給電源電圧が前記基準電源電圧以下の場合にローレベルからハイレベルに反転する瞬時変動検知信号を前記電圧処理部へ出力する電源電圧監視回路を備え、
前記電圧処理部は、前記瞬時変動検知信号の立上りエッジに同期して瞬時変動検知信号の状態をラッチするラッチ回路と、前記ラッチ回路の出力が退避される内部メモリとを備えており、
前記セル電圧検出処理にて、前記A/D変換後に、前記退避が実行され、前記退避の実行後に前記ラッチ回路のリセットが実行され、前記リセットの実行後に、前記内部メモリに退避された前記ラッチ回路の出力レベルに基づいて、前回のセル電圧検出処理にて前記リセットが実行されたタイミングから今回のセル電圧検出処理にて前記退避が実行されたタイミングまでの期間に前記外部供給電源電圧の瞬時変動が発生していたか否かを判定し、前記期間に前記外部供給電源電圧の瞬時変動が発生していた場合に前記期間内に収集した前記セル電圧検出データを破棄することを特徴とする電池電圧検出装置。
