Abstract
【解決手段】
低圧系CPU30から電圧検出回路11に対して対応するブロックB1全体の両端電圧値を検出させ、次にブロックB1内の単位セルC11〜C1nの中から任意に1つを選択して、その選択単位セルの両端電圧値を検出させて、ブロックB1全体の両端電圧と選択単位セルの両端電圧値とブロックB1の単位セル数nとの積を比較し、ブロックB1全体の両端電圧値と選択単位セルの両端電圧値とブロックB1の単位セル数nとの積が所定値以上の差がある場合か、ブロックB1の両端電圧値と選択単位セルの両端電圧値とブロックB1の単位セル数nとの積のいずれかがブロック電圧の規格値の範囲外にある場合は車載バッテリに異常があると判断する。
