Title (EN) BALANCING DEVICE
(FR) DISPOSITIF D'ÉQUILIBRAGE
(JA) 均等化装置
Abstract:
(EN) A battery (1) is configured by connecting a plurality of battery cells (11) in series. When performing balancing for reducing the differences among the inter-terminal voltage values between the battery cells (11) of the battery (1), the battery cells (11) are divided into a plurality of groups (62) in consideration of an average value (61) calculated from the inter-terminal voltage values of the respective battery cells (11). The balancing is performed for each of the groups (62) so as to make the inter-terminal voltage values of the respective battery cells (11) belonging to the each of the groups (62) closer to the average value (61).
(FR) La présente invention concerne une batterie (1) qui est conçue en connectant une pluralité de cellules de batterie (11) en série. Lors de la réalisation d'un équilibrage pour réduire les différences parmi les valeurs de tension inter-bornes entre les cellules de batterie (11) de la batterie (1), les cellules de batterie (11) sont divisées en une pluralité de groupes (62) en fonction d'une valeur moyenne (61) calculée à partir des valeurs de tension inter-bornes des cellules de batterie (11) respectives. L'équilibrage est réalisé pour chacun des groupes (62) afin de faire en sorte que les valeurs de tension inter-bornes des cellules de batterie (11) respectives qui appartiennent à chacun des groupes (62) soient plus proches de la valeur moyenne (61).
(JA)  電池1は、複数の電池セル11が直列に接続された構成である。電池1の各電池セル11の間の端子間電圧値の差を低減する均等化を行う場合、各電池セル11は、各電池セル11の端子間電圧値から計算された平均値61を考慮して、複数のグループ62に分けられる。均等化は、グループ62毎に、そのグループ62に属する各電池セル11の端子間電圧値を平均値61に近づけるように行われる。
