Abstract: front page image
(EN) The present invention provides a charging control apparatus and method which can achieve energy saving and quick cell balancing. According to the present invention, charging is suspended when one of a plurality of battery cells reaches a fully charged state. In addition, a battery cell, the state of charge of which is lowest, is determined to be supplementarily charged, and the other battery cells are determined to be forcedly discharged. Subsequently, cell balancing including supplementary charging and forced discharging is performed. When the number of the battery cells which, among the forcedly discharged battery cells, have the same state of charge as that of the supplementarily charged battery cell, is equal to or greater than a reference number, the cell balancing is stopped and charging is resumed. The cell balancing procedure is repeated whenever one of the plurality of battery cells reaches a fully charged state. The present invention can reduce energy waste in the process of performing cell balancing through forced discharging, and reduce the time required to charge a battery cell up to a fully charged state.
(FR) La présente invention concerne un appareil et un procédé de commande de charge qui peuvent réaliser une économie d'énergie et un équilibrage rapide d'éléments. Selon la présente invention, la charge est suspendue lorsqu'un élément d'une pluralité d'éléments de batterie atteint un état de charge complète. De plus, un élément de batterie, dont l'état de charge est la plus faible, est déterminé comme étant chargé de manière supplémentaire, et les autres éléments de batterie sont déterminés comme étant déchargés de manière forcée. Par la suite, un équilibrage d'éléments comprenant une charge supplémentaire et une décharge forcée est effectué. Lorsque le nombre d'éléments de batterie qui, parmi les éléments de batterie déchargés de manière forcée, ont le même état de charge que celui de l'élément de batterie chargée de manière supplémentaire, est supérieur ou égal à un nombre de référence, l'équilibrage d'éléments est arrêté et la charge est reprise. La procédure d'équilibrage d'éléments est répétée chaque fois qu'un élément de la pluralité d'éléments de batterie atteint un état de charge complète. La présente invention permet de réduire le gaspillage d'énergie dans le processus de réalisation d'un équilibrage d'éléments par décharge forcée, et de réduire le temps nécessaire pour charger un élément de batterie jusqu'à un état de charge complète.
(KO) 본 발명은, 에너지 절약 및 빠른 셀 밸런싱이 가능한 충전 제어 장치 및 방법을 개시한다. 본 발명에 따르면, 복수의 배터리 셀들 중 어느 하나가 만충전 상태에 도달되면 충전이 일시 중지된다. 또한, 충전 상태가 가장 낮은 배터리 셀이 보조 충전 대상으로, 나머지 배터리 셀들이 강제 방전 대상으로 결정된다. 이어서, 보조 충전 및 강제 방전을 포함하는 셀 밸런싱이 이루어진다. 강제 방전되는 배터리 셀들 중에서 보조 충전되는 배터리 셀과 충전 상태가 동일한 배터리 셀의 수가 기준 넘버 이상이 되면, 셀 밸런싱이 중단되고 충전이 재개된다. 이러한 셀 밸런싱 과정은 복수의 배터리 셀들 중 어느 하나가 만충전 상태에 도달될 때마다 반복된다. 본 발명은, 강제 방전을 통한 셀 밸런싱 과정에서 에너지 낭비를 줄이고 만충전 상태까지 충전하는데 소요되는 시간을 줄일 수 있다.
