The present invention relates to an apparatus and a method for equalizing the energy of a plurality of parallel-connected batteries. The apparatus may comprise: a matrix-switch module which comprises a plurality of switching elements and forms charging paths or discharging paths for respective plurality of batteries; a bi-directional converter which charges, by a predetermined charging current, at least one of the batteries connected through the matrix-switch module, or discharges same by a predetermined discharging current; and an operation device which, on the basis of an operation mode of the apparatus and the respective states of charge of the batteries, controls the matrix-switch module and the bi-directional converter in order to equalize the energy of the plurality of batteries.

    La présente invention concerne un appareil et un procédé d'égalisation de l'énergie d'une pluralité de batteries connectées en parallèle. L'appareil peut comprendre : un module de commutateur matriciel qui comprend une pluralité d'éléments de commutation et forme des chemins de charge ou des chemins de décharge pour une pluralité respective de batteries ; un convertisseur bidirectionnel qui charge, par un courant de charge prédéterminé, au moins une des batteries, connectée par l'intermédiaire du module de commutateur matriciel, ou la décharge par un courant de décharge prédéterminé ; et un dispositif de commande qui, sur la base d'un mode de fonctionnement de l'appareil et des états de charge respectifs des batteries, commande le module de commutateur matriciel et le convertisseur bidirectionnel afin d'égaliser l'énergie de la pluralité de batteries.

    본 발명은 병렬 연결된 다수의 배터리들의 에너지를 균등화하는 장치 및 방법에 관한 것이다. 상기 장치는 다수의 스위칭 소자를 포함하며, 상기 다수의 배터리들 각각에 대한 충전 경로 또는 방전 경로를 형성하는 매트릭스 스위치 모듈(matrix-switch module); 상기 매트릭스 스위치 모듈을 통해 연결된 적어도 하나의 배터리를 기 설정된 충전 전류로 충전하거나, 기 설정된 방전 전류로 방전하는 양방향 컨버터(bi-directional converter); 및 상기 장치의 동작 모드 및 각 배터리의 충전 상태에 기초하여, 상기 다수의 배터리들의 에너지를 균등화하기 위해 상기 매트릭스 스위치 모듈 및 상기 양방향 컨버터를 제어하는 연산장치를 포함할 수 있다.
