Abstract
【解決手段】電池システムの制御部は、電流センサによる電流検出値と、バッテリの入出力電流値の理論値と、の比較に基づいて電流検出値の異常の有無を判定する検出値判定部と、充放電電力許容値がゼロになってからの経過時間である判定用継続時間に対する、電流検出値が異常と判定された回数の比率を異常比率として算出する異常比率算出部と、充電電力許容値がゼロの期間中に電流検出値の積算値が充電側に増加して充電側閾値に達した場合、または、放電電力許容値がゼロの期間中に電流検出値の積算値が放電側に増加して放電側閾値に達した場合であって、異常比率が基準比率以上の場合には、電流センサが異常であると判定する異常判定部と、を含む。
