Title (EN) BATTERY MANAGEMENT APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE GESTION DE BATTERIE
(KO) 배터리 관리 장치 및 방법
Abstract:
(EN) Disclosed is a battery management apparatus and method. The battery management apparatus according to an embodiment of the present invention may be configured to: when the voltage of a battery being discharged is equal to or less than a predetermined discharge threshold voltage, estimate the time left until a predetermined lower-limit discharge voltage less than the discharge threshold voltage is reached, starting from the current time point; and maintain or adjust output parameters of the battery according to the estimated left time.
(FR) La présente invention concerne un appareil et un procédé de gestion de batterie. L'appareil de gestion de batterie selon un mode de réalisation de la présente invention peut être configuré, lorsque la tension d'une batterie en cours de décharge est égale ou inférieure à une tension de seuil de décharge prédéterminée, pour estimer le temps restant jusqu'à ce qu'une tension de décharge de limite inférieure prédéterminée inférieure à la tension de seuil de décharge est atteinte, à partir de l'instant courant; et pour maintenir ou ajuster des paramètres de sortie de la batterie en fonction du temps restant estimé.
(KO) 배터리 관리 장치와 방법을 개시한다. 본 발명의 일 실시예에 따른 배터리 관리 장치는, 방전 중인 배터리의 전압이 미리 정해진 방전 임계 전압과 같거나 더 낮은 경우, 현 시점부터 상기 방전 임계 전압보다 낮게 미리 정해진 방전 하한 전압에 도달할 때까지의 잔여 시간을 예측하고, 예측된 잔여 시간에 따라 배터리의 출력 파라미터를 유지 또는 조절하도록 구성될 수 있다.
