Abstract:
(EN) The present invention relates to an apparatus and method for voltage balancing between battery racks, and is characterized by comprising: a voltage measurement unit for measuring voltages of a plurality of battery racks; a collection unit for collecting the measured voltages of the plurality of battery racks; and a control unit for performing control so as to perform voltage balancing between two battery racks among the plurality of battery racks, and repeatedly perform voltage balancing between the battery racks subjected to voltage balancing and each battery rack not subjected to voltage balancing, on the basis of the collected voltages of the plurality of battery racks.
(FR) La présente invention concerne un appareil et un procédé d'équilibrage de tension entre bâtis de batterie, l'appareil étant caractérisé en ce qu'il comprend : une unité de mesure de tension destinée à mesurer les tensions d'une pluralité de bâtis de batterie ; une unité de collecte destinée à collecter les tensions mesurées de la pluralité de bâtis de batterie ; et une unité de commande destinée à commander de sorte à effectuer un équilibrage de tension entre deux bâtis de batterie parmi la pluralité de bâtis de batterie, et à effectuer de façon répétée un équilibrage de tension entre les bâtis de batterie soumis à un équilibrage de tension et chaque bâti de batterie non soumis à un équilibrage de tension, sur la base des tensions collectées de la pluralité de bâtis de batterie.
(KO) 본 발명은 배터리 랙 간 전압 밸런싱 장치 및 방법에 관한 것으로서, 복수의 배터리 랙의 전압을 측정하는 전압 측정부; 측정한 상기 복수의 배터리 랙 전압을 수집하는 수집부; 및 수집한 상기 복수의 배터리 랙 전압에 근거하여, 상기 복수의 배터리 랙 중 2개의 배터리 랙 상호 간의 전압 밸런싱을 수행하고, 상기 전압 밸런싱을 수행한 배터리 랙과 전압 밸런싱을 수행하지 않은 배터리 랙과의 전압 밸런싱을 반복적으로 수행하도록 제어하는 제어부;를 포함하는 것을 특징으로 한다.
