Title (EN) ELECTRICITY STORAGE SYSTEM AND MANAGEMENT DEVICE
(FR) SYSTÈME ACCUMULATEUR D’ÉLECTRICITÉ ET DISPOSITIF DE GESTION
(JA) 蓄電システム、管理装置
Abstract:
(EN) Provided is an electricity storage system in which a management unit (50m), on the basis of a state of power (SOP) of each unit of a plurality of electricity storage blocks (10-30) connected in parallel, and a current flowing through each of the electricity storage blocks (10-30), calculates the SOP of the plurality of electricity storage blocks (10-30) as a whole, and sets an upper limit value of the power or current of at least one of charging and discharging of a power conversion unit (60), on the basis of the overall SOP that has been calculated. The management unit (50m), before the power conversion unit (60) starts power conversion, estimates the current that flows through each of the electricity storage blocks (10-30), from the voltage and internal resistance of each of the electricity storage blocks (10-30).
(FR) L’invention concerne un système accumulateur d’électricité dans lequel une unité de gestion (50m), sur la base d’un état de puissance (SOP) de chaque unité d’une pluralité de blocs accumulateurs d’électricité (10-30) connectés en parallèle, et un courant circulant à travers chacun des blocs accumulateurs d’électricité (10-30), calcule le SOP de la pluralité de blocs accumulateurs d’électricité (10-30) dans son ensemble, et règle une valeur limite supérieure de la puissance ou du courant d’au moins la charge ou la décharge d’une unité de conversion de puissance (60), sur la base du SOP total qui a été calculé. L’unité de gestion (50m), avant que l’unité de conversion de puissance (60) commence la conversion de puissance, estime le courant qui circule à travers chacun des blocs accumulateurs d’électricité (10-30), à partir de la tension et de la résistance interne de chacun des blocs accumulateurs d’électricité (10-30).
(JA) 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)と、各蓄電ブロック(10-30)に流れる電流に基づいて複数の蓄電ブロック(10-30)全体のSOPを算出し、算出した全体のSOPをもとに電力変換部(60)の充電および放電の少なくとも一方の電力または電流の上限値を設定する。管理部(50m)は、電力変換部(60)が電力変換を開始する前、各蓄電ブロック(10-30)に流れる電流を、各蓄電ブロック(10-30)の電圧と内部抵抗から推定する。
