(KO) 배터리 수명 추정 방법 및 장치
Abstract: front page image
(EN)A method for estimating the lifespan of a battery according to the present invention may comprise the steps of: fully discharging a battery; partially charging the fully-discharged battery according to a predetermined charging condition; acquiring pieces of voltage information at multiple predetermined measurement time points while partially charging the fully-discharged battery; and calculating the remaining capacity of the battery, using the acquired pieces of voltage information. An apparatus for estimating the lifespan of a battery according to the present invention may comprise: a reference data storage unit for storing pieces of reference information, on the basis of which the lifespan of a battery is estimated; a charge/discharge control unit for fully discharging a battery, the lifespan of which is to be estimated, and then partially charging the fully-discharged battery according to a predetermined charging condition; a voltage information acquisition unit for acquiring pieces of voltage information of the battery when multiple predetermined measurement time points are reached while the fully-discharged battery is partially charged; and a remaining capacity calculation unit for calculating the remaining capacity of the battery, using the acquired pieces of voltage information and the pieces of reference information.
(FR)Un procédé d'estimation de la durée de vie d'une batterie, selon la présente invention, peut comprendre les étapes consistant à : décharger complètement une batterie; charger partiellement la batterie complètement déchargée selon une condition de charge prédéterminée; acquérir des éléments d'informations de tension à de multiples points temporels de mesure prédéterminés tout en chargeant partiellement la batterie complètement déchargée; et calculer la capacité restante de la batterie à l'aide des éléments d'informations de tension acquis. Un appareil pour estimer la durée de vie d'une batterie, selon la présente invention, peut comprendre : une unité de stockage de données de référence pour stocker des éléments d'informations de référence sur la base desquels la durée de vie d'une batterie est estimée; une unité de commande de charge/décharge pour décharger complètement une batterie, dont la durée de vie doit être estimée, et charger ensuite partiellement la batterie complètement déchargée selon une condition de charge prédéterminée; une unité d'acquisition d'informations de tension pour acquérir des éléments d'informations de tension de la batterie lorsque de multiples points temporels de mesure prédéterminés sont atteints tandis que la batterie complètement déchargée est partiellement chargée; et une unité de calcul de capacité restante pour calculer la capacité restante de la batterie à l'aide des éléments d'informations de tension acquis et des éléments d'informations de référence.
(KO)본 발명의 배터리 수명 추정 방법은, 배터리를 완전 방전시키는 단계; 완전 방전시킨 배터리를 소정의 충전 조건에 맞추어 일부 충전시키는 단계; 상기 일부 충전시키면서 전압 정보를 복수의 소정 측정 시점들에서 획득하는 단계; 및 상기 획득된 전압 정보들을 이용하여 상기 배터리의 잔여 용량을 산정하는 단계를 포함할 수 있다. 본 발명의 배터리 수명 추정 장치는, 배터리 수명 추정의 기준이 되는 기준 정보들을 저장하는 기준 데이터 저장부; 수명 추정의 대상이 되는 배터리를 완전 방전시키고 나서, 소정의 충전 조건에 따라 일부를 충전시키는 충방전 제어부; 상기 일부 방전 도중 복수의 소정 측정 시점들에 도달하면 상기 배터리에 대한 전압 정보를 획득하는 전압 정보 획득부; 상기 획득된 전압 정보들과 상기 기준 정보들을 이용하여 상기 배터리의 잔여 용량을 산정하는 잔여 용량 산출부를 포함할 수 있다.
