Abstract
(EN)
A battery device: receives an SOC configuration range; charges at least one battery pack; estimates an SOC on the basis of state information of the at least one battery pack; monitors whether the estimated SOC reaches a charge reference value corresponding to an upper limit of the SOC configuration range; and as a result of monitoring, when the estimated SOC reaches the charge reference value, can stop charging. The SOC configuration range is determined on the basis of travel information of a vehicle, and may be within an SOC limit range in which the degree of degradation of battery cells constituting the at least one battery pack is the lowest.
(FR)
L'invention concerne un dispositif batterie qui : reçoit une plage de configuration de SOC; charge au moins un bloc-batterie; estime un SOC sur la base d'informations d'état dudit bloc-batterie; surveille si le SOC estimé atteint une valeur de référence de charge correspondant à une limite haute de la plage de configuration de SOC; et, consécutivement à la surveillance, lorsque le SOC estimé atteint la valeur de référence de charge, peut arrêter la charge. La plage de configuration de SOC est déterminée sur la base d'informations de déplacement d'un véhicule, et peut s'inscrire dans une plage de limite de SOC dans laquelle le degré de dégradation de cellules de batterie constituant ledit bloc-batterie est le plus faible.

배터리 장치는 SOC 설정 범위를 수신하고, 적어도 하나의 배터리 팩을 충전하며, 상기 적어도 하나의 배터리 팩의 상태 정보에 기초하여 SOC를 추정하고, 상기 추정된 SOC가 상기 SOC 설정 범위의 상한에 대응하는 충전 기준 값에 도달하는지 모니터링 하며, 상기 모니터링 결과 상기 추정된 SOC가 상기 충전 기준 값에 도달하면 충전을 중지할 수 있다. 상기 SOC 설정 범위는 자동차의 운행 정보에 기초하여 결정되고, 상기 적어도 하나의 배터리 팩을 구성하는 배터리 셀의 열화가 가장 낮은 SOC 제한 범위 내일 수 있다.
