Abstract
(EN)
In the present invention, a battery 50 that does not have a function of communicating with an alternator 10B comprises: a plurality of secondary batteries 62; an interrupter 55 connected to the plurality of secondary batteries 62 in series; an equalization circuit 25 that equalizes the voltage of the plurality of secondary batteries 62; and a management unit 130. In a state in which the interrupter 55 is turned OFF, the management unit 130 equalizes the voltage of each of the secondary batteries 62 using the equalization circuit 25, and the management unit turns ON the interrupter 55 after equalizing the voltage of each of the secondary batteries 62.

Dans la présente invention, une batterie (50) qui ne dispose pas de fonction de communication avec un alternateur (10B), comprend : une pluralité de batteries secondaires (62) ; un interrupteur (55) connecté à la pluralité de batteries secondaires (62) en série ; un circuit d'égalisation (25) qui égalise la tension de la pluralité de batteries secondaires (62) ; et une unité de gestion (130). Dans un état dans lequel l'interrupteur (55) est éteint, l'unité de gestion (130) égalise la tension de chacune des batteries secondaires (62) à l'aide du circuit d'égalisation (25), et l'unité de gestion allume l'interrupteur (55) après égalisation de la tension de chacune des batteries secondaires (62).
(JA)
オルタネータ10Bと通信する機能を有しないバッテリ50であって、複数の二次電池62と、複数の二次電池62と直列に接続されている遮断器55と、複数の二次電池62の電圧を均等化する均等化回路25と、管理部130と、を備え、管理部130は、遮断器55がオフの状態で均等化回路25によって各二次電池62の電圧を均等化し、各二次電池62の電圧を均等化した後に遮断器55をオンにする。
