Title
(EN) CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE
(JA) 制御装置
Abstract
(EN)
This control device (20), which limits the maximum power (WB) at which power can be inputted and outputted from a power storage device when an inter-terminal voltage (CCV) during charging and discharging of a power storage device (11) belongs to a prescribed limit range (XH, XL) in a high power storage state or a low power storage state of the power storage device, comprises: a current acquisition unit (S18) that acquires a current (IB) during charging and discharging of the power storage device at prescribed periods; and range setting units (S40, 54) that variably set the limit range on the basis of the current acquired by the current acquisition unit.
(FR)
La présente invention concerne un dispositif de commande (20), qui limite la puissance maximale (WB) à laquelle de l’énergie peut être entrée et délivrée à partir d'un dispositif de stockage d'énergie lorsqu'une tension entre bornes (CCV) pendant la charge et la décharge d'un dispositif de stockage d'énergie (11) appartient à une plage limite prescrite (XH, XL) dans un état de stockage d'énergie élevé ou un état de stockage d'énergie faible du dispositif de stockage d'énergie, lequel dispositif de commande comprend : une unité d'acquisition de courant (S18) qui acquiert un courant (IB) pendant la charge et la décharge du dispositif de stockage d'énergie à des périodes prescrites ; et des unités de réglage de plage (S40, 54) qui règlent de manière variable la plage limite sur la base du courant acquis par l'unité d'acquisition de courant.
(JA)
蓄電装置(11)の充放電中の端子間電圧(CCV)が、蓄電装置の高蓄電状態、又は低蓄電状態における所定の制限範囲(XH,XL)に属する場合に、蓄電装置からの電力の入出力が可能な最大電力(WB)を制限する制御装置(20)であって、蓄電装置の充放電中の電流(IB)を所定周期で取得する電流取得部(S18)と、電流取得部により取得された電流に基づいて制限範囲を可変に設定する範囲設定部(S40,54)と、を備える。
