Abstract
(EN) A management device (30) manages a plurality of power storage modules (M1) connected in parallel to power sources (60, 2) via respective switches (RY1). In a state where switches (RY1) connected to some of the plurality of power storage modules (M1) are on and switches (RY1) connected to the remaining power storage modules (M1) are off, if the turning on of at least one of the switches (RY1) in the off state will result in the upper limit of the current or power that is permitted to be supplied to all of the plurality of power storage modules (M1) when that switch (RY1) is turned on being lower than a threshold based on the upper limit before that switch (RY1) is turned on, a determination unit (313) of the management device (30) does not permit the turning on of that switch (RY1).
(FR) Un dispositif de gestion (30) gère une pluralité de modules de stockage d'énergie (M1) connectés en parallèle à des sources d'alimentation (60) par l'intermédiaire d'interrupteurs (RY1) respectifs. Lorsque les commutateurs (RY1) connectés à certains modules de la pluralité de modules de stockage d'énergie (M1) sont à l'état de marche et que les commutateurs (RY1) connectés aux reste des modules de stockage d'énergie (M1) sont à l'arrêt, si la mise en marche d'au moins un des commutateurs (RY1) à l'arrêt entraîne le fait que la limite supérieure du courant ou de l'énergie pouvant être fourni(e) à la totalité de la pluralité de modules de stockage d'énergie (M1) lorsque ce commutateur (RY1) est mis en marche, est inférieure à un seuil sur la base de la limite supérieure avant que le commutateur (EY1) soit mis en marche, une unité de détermination (313) du dispositif de gestion (30) ne permet pas la mise en marche de ce commutateur (RY1).
(JA) 管理装置(30)は、電源(60、2)に対して、それぞれスイッチ(RY1)を介して並列に接続される複数の蓄電モジュール(M1)を管理する。管理装置(30)の判定部(313)は、複数の蓄電モジュール(M1)の内、一部の蓄電モジュール(M1)に接続されたスイッチ(RY1)がオン、残りの蓄電モジュール(M1)に接続されたスイッチ(RY1)がオフの状態において、前記オフ状態のスイッチ(RY1)の少なくとも一つをターンオンするとき、当該スイッチ(RY1)をターンオンした場合の、複数の蓄電モジュール(M1)全体に充電することが許容される電流または電力の上限値が、当該スイッチ(RY1)をターンオンする前の当該上限値にもとづく閾値より低いとき、当該スイッチ(RY1)のターンオンを許可しない。
