Abstract
【解決手段】直列接続された複数の蓄電セルからなる集合電池において、蓄電セル間又は直列接続された複数の蓄電セルからなる蓄電モジュール間の電圧を均等化するバランス補正装置において、蓄電モジュールの夫々に対する電流の供給を第1のデューティ比でオンオフ制御することにより、蓄電モジュールの夫々が共通に接続する素子を介して蓄電モジュール間での電力の授受を生じさせて蓄電モジュール間の電圧を均等化させ、第1のデューティ比とは異なる第2のデューティ比でオンオフ制御を行う期間を生じさせ、蓄電モジュールの端子間に接続している容量素子C1,C2に印加される電圧を計測し、上記期間中に容量素子C1,C2に印加される電圧の変化に基づき容量素子C1,C2と蓄電モジュールとを結ぶ線路の断線の有無を判定する。
