A battery system according to an embodiment of the present invention is a battery system which includes a battery rack including a plurality of battery module assemblies (BMAs). The battery system may comprise: a first battery management device (RBMS) which controls the battery rack, the first battery management device identifying, at predetermined periods, a condition for performing BMA balancing according to a state of charge and whether the battery system is in an idle state, and if the condition for performing BMA balancing is satisfied, setting a BMA balancing target and a BMA balancing time; and a second battery management device (PBMS) which is located in each of the BMAs and includes a balancing circuit, the second battery management device receiving a BMA balancing command including the BMA balancing target and the BMA balancing time from the first battery management device to perform cell balancing.

    Un système de batterie selon un mode de réalisation de la présente invention consiste en un système de batterie qui comprend un bâti de batterie comprenant une pluralité d'ensembles modules de batterie (BMA). Le système de batterie peut comporter : un premier dispositif de gestion de batterie (RBMS) qui commande le bâti de batterie, le premier dispositif de gestion de batterie identifiant, à des périodes prédéterminées, une condition pour effectuer un équilibrage de BMA en fonction d' un état de charge et suivant que le système de batterie est ou non dans un état de repos, et si la condition pour effectuer l'équilibrage de BMA est satisfaite, spécifiant une cible d'équilibrage de BMA et un temps d'équilibrage de BMA ; et un second dispositif de gestion de batterie (PBMS) qui est situé dans chacun des BMA et comprend un circuit d'équilibrage, le second dispositif de gestion de batterie recevant une consigne d'équilibrage de BMA incluant la cible d'équilibrage de BMA et le temps d'équilibrage de BMA en provenance du premier dispositif de gestion de batterie pour effectuer l'équilibrage d'éléments.

    본 발명의 일 실시예에 따른 배터리 시스템은 복수의 배터리 모듈 어셈블리(BMA)를 포함하는 배터리 랙을 포함하는 배터리 시스템으로서, 상기 배터리 랙을 제어하는 제1 배터리 관리 장치(RBMS)로서, 일정 주기로, 상기 배터리 시스템이 휴지(idle) 상태인지 여부 및 충전 상태에 따라 BMA 밸런싱 수행 조건을 확인하고, 상기 BMA 밸런싱 수행 조건이 만족된 경우, BMA 밸런싱 대상 및 BMA 밸런싱 시간을 설정하는, 제1 배터리 관리 장치; 및 BMA 내에 위치하고 밸런싱 회로를 포함하는 제2 배터리 관리 장치(PBMS)로서, 상기 제1 배터리 관리 장치로부터 상기 BMA 밸런싱 대상 및 BMA 밸런싱 시간을 포함하는 BMA 밸런싱 명령을 수신하여 셀 밸런싱을 수행하는, 제2 배터리 관리 장치를 포함할 수 있다.
