Abstract
【解決手段】複数のセルグループ10の各々は、互いに直列に接続される複数のセル11を含み、複数のセルグループ10はそれぞれ複数の配線経路W1の上に設けられる。スイッチ2は複数の配線経路W1において、複数のセルグループ10に対してそれぞれ直列に接続される。劣化診断部31は複数のセルグループ10のうち、劣化が生じた劣化セルグループ10を特定する。切替制御部32は複数のスイッチ2のうち、劣化セルグループ10に接続される劣化スイッチ2をオフする。
【選択図】図1
Description
図1は、車載用電源システム100の構成の一例を概略的に示す図である。この車載用電源システムは車両に搭載される。図1に示すように、車載用電源システム100は車載用電源装置110と発電機4と車両負荷5とを備えている。車載用電源装置110は蓄電装置1と複数のスイッチ2と制御部3とを備えている。蓄電装置1は例えば蓄電池(例えば鉛蓄電池)であり、複数のセルグループ10を有している。複数のセルグループ10の各々は複数のセル11を備えている。セル11は電池の最小単位を構成している。各セルグループ10において、複数のセル11は相互に直列に接続されている。図1の例示では、各セルグループ10において4つのセル11が示されているものの、セル11の個数は適宜に変更することができる。
図4は車載用電源システム100の構成の一例を概略的に示す図である。第1の実施の形態と比較して、車載用電源システム100には、これが搭載される車両のイグニッションのオン/オフを切換えるイグニッションスイッチ7が更に設けられている。イグニッションスイッチ7のオン/オフ状態を示す信号IG1は切替制御部32へと入力される。ユーザ操作によって、イグニッションスイッチ7がターンオンすると、例えば、切替制御部32は適宜にスイッチ2をオンして蓄電装置1から車両負荷5へと適宜に給電を行う。
