Description
<車両の構成>
図1は、本実施の形態に係る車両の全体構成を概略的に示すモジュール図である。車両1は、たとえば電気自動車であって、充電ケーブル910により車両外部の充電装置900と電気的に接続可能に構成されている。充電装置900は、充電ケーブル910を介して、系統電源(たとえば商用電源)920からの交流電力を車両1に供給する。
以上のように構成された組電池10において、あるモジュール内のいずれかのセルのヒューズが溶断したりCIDが作動したりすることで、当該セルの電流経路が遮断される(言い換えると断線が生じる)場合がある。そうすると、そのセルを流れるべきであった電流が他の正常なセル(断線したセルに並列接続された残りのセル)を流れることになる。したがって、断線が発生したモジュール内では、断線が発生していないモジュールと比べて、正常なセルを流れる電流が増加する。その結果、断線が発生したモジュール内の正常なセルを過大な電流が流れ、正常なセルを適切に保護することができない可能性が生じる。したがって、いずれかのモジュール内において断線が発生したか否かを診断することが求められる。
図3は、組電池10の断線診断処理に至るまでの一連の処理の概要を説明するためのタイムチャートである。図3において、横軸は経過時間を示す。縦軸は、組電池10のSOCを示す。なお、縦軸を組電池10のOCV(たとえば全セルの平均OCV)に読み替えてもよい。
図4は、本実施の形態における組電池10の断線診断に関する処理全体を示すフローチャートである。このフローチャートは、所定条件が成立した場合に演算周期が経過する毎にメインルーチン(図示せず)から呼び出されて実行される。このフローチャートに含まれる各ステップ(以下、「S」と略す)は、基本的にはECU100によるソフトウェア処理によって実現されるが、ECU100内に作製された専用のハードウェア(電気回路)によって実現されてもよい。
