Title (EN) BATTERY CHARGING/DISCHARGING CONTROL DEVICE AND METHOD FOR CONTROLLING SAME
(FR) DISPOSITIF DE COMMANDE DE CHARGE/DÉCHARGE DE BATTERIE ET SON PROCÉDÉ DE COMMANDE
(KO) 배터리의 충방전 제어 장치 및 그 제어 방법
Abstract: front page image
(EN)A battery charging/discharging control device charges a battery with a constant current in a constant current mode and is switched to a constant voltage mode to charge the battery with a constant voltage when a voltage of the battery corresponds to an end-of-charge voltage. The end-of-charge voltage is set to a first end-of-charge voltage obtained by subtracting a cathode threshold potential from a full charge voltage of the battery, wherein the cathode threshold potential is a potential value of a cathode causing a phase change of an anode active material contained in the battery.
(FR)Un dispositif de commande de charge/décharge de batterie charge une batterie avec un courant constant dans un mode de courant constant et est commuté vers un mode de tension constante pour charger la batterie avec une tension constante lorsque la tension de la batterie correspond à une tension de fin de charge. La tension de fin de charge est fixée à une première tension de fin de charge obtenue en soustrayant un potentiel de seuil de cathode d'une tension de charge complète de la batterie, le potentiel de seuil de cathode étant une valeur de potentiel d'une cathode provoquant un changement de phase d'une matière active d'anode contenue dans la batterie.
(KO)배터리의 충방전 제어 장치는, 정전류 모드(constant current mode)에서 상기 배터리를 정전류로 충전시키고, 상기 배터리의 전압이 충전 종지 전압(end-of-charge voltage)과 대응할 때, 정전압 모드(constant voltage mode)로 전환되어 상기 배터리를 정전압으로 충전시킨다. 상기 충전 종지 전압은 상기 배터리의 만충전 전압으로부터 음극 임계 전위를 차감한 제1 충전 종지 전압으로 설정되고, 상기 음극 임계 전위는 상기 배터리에 포함된 음극 활물질이 상변이를 일으키는 음극의 전위값이다.
