Title (EN) ELECTRICITY STORAGE SYSTEM AND MANAGEMENT DEVICE
(FR) SYSTÈME DE STOCKAGE ET DISPOSITIF DE GESTION D'ÉLECTRICITÉ
(JA) 蓄電システム、管理装置
Abstract:
(EN) A management unit (50m) of an electricity storage system (1) calculates, on the basis of the SOP (State of Power) of each one of a plurality of electricity storage blocks (10-30) connected in parallel, the total SOP of the plurality of electricity storage blocks (10-30). When at least one (10) of the plurality of electricity storage blocks (10-30) is paralleled off and then the at least one electricity storage block (10) returns to the parallel connection after at least one switch (40a) is turned on, the management unit (50m) calculates the total SOP of the electricity storage blocks (10-30) after the return of the electricity storage block (10) on the basis of the variation in current flowing through each one of the electricity storage blocks (10-30) after the return and sets the upper limit value of power or current to be flowed through a power conversion unit (60).
(FR) Selon l'invention, une unité de gestion (50m) d'un système de stockage d'électricité (1) calcule, sur la base de l'état de puissance (SOP) de chacun d'une pluralité de blocs de stockage d'électricité (10-30) connectés en dérivation, l'état de puissance total de la pluralité de blocs de stockage d'électricité (10-30). Lorsqu'au moins un (10) de la pluralité de blocs de stockage d'électricité (10-30) est déconnecté, puis le(s) bloc(s) de stockage d'électricité (10) est/sont reconnecté(s) en dérivation après la mise à l'état passant d'au moins un commutateur (40a), l'unité de gestion (50m) calcule l'état de puissance total des blocs de stockage d'électricité (10-30) après reconnexion du bloc de stockage d'électricité (10) sur la base de la variation du courant circulant à travers chacun des blocs de stockage d'électricité (10-30) après la reconnexion et détermine la valeur limite supérieure de la puissance ou du courant à acheminer à travers une unité de conversion de puissance (60).
(JA) 蓄電システム(1)において、管理部(50m)は、並列接続された複数の蓄電ブロック(10-30)の各単体のSOP(State Of Power)に基づいて複数の蓄電ブロック(10-30)全体のSOPを算出する。管理部(50m)は、複数の蓄電ブロック(10-30)の少なくとも1つ(10)が解列した状態から、当該少なくとも1つのスイッチ(40a)がターンオンして当該少なくとも1つの蓄電ブロック(10)が並列接続に復帰するとき、当該蓄電ブロック(10)の復帰後の蓄電ブロック(10-30)全体のSOPを復帰後の蓄電ブロック(10-30)の各単体の電流バラツキに基づいて算出し、電力変換部(60)に流す電力または電流の上限値を設定する。
