The present invention relates to a battery state of health (SOH) estimating method and a battery system providing same. The battery system of the present invention comprises a battery and a battery management system (BMS) which obtains a degradation condition related to degradation of the battery at each predetermined monitoring cycle, determines a relational expression representing the relationship between the total amount of energy of the battery and the SOH of the battery according to the degradation condition at each of the monitoring cycles, and estimates the SOH of the battery according to the relational expression, wherein the total amount of energy of the battery is the sum of the charging energy and the discharging energy of the battery.

    La présente invention concerne un procédé d'estimation d'état de santé (SOH) de batterie et un système de batterie fournissant celui-ci. Le système de batterie de la présente invention comprend une batterie et un système de gestion de batterie (BMS) qui obtient un état de dégradation associé à la dégradation de la batterie à chaque cycle de surveillance prédéterminé, détermine une expression relationnelle représentant la relation entre la quantité totale d'énergie de la batterie et le SOH de la batterie en fonction de l'état de dégradation à chacun des cycles de surveillance, et estime le SOH de la batterie selon l'expression relationnelle, la quantité totale d'énergie de la batterie étant la somme de l'énergie de charge et de l'énergie de décharge de la batterie.

    본 발명은, 배터리 SOH(State of Health) 추정 방법 및 그 방법을 제공하는 배터리 시스템에 관한 것으로, 본 발명의 배터리 시스템은 배터리 및 소정의 모니터링 주기마다, 상기 배터리의 퇴화에 관련된 퇴화 조건을 획득하고, 상기 모니터링 주기마다, 상기 퇴화 조건에 따라 상기 배터리의 에너지 총량과 상기 배터리의 SOH 간의 관계를 나타내는 관계식을 결정하여 상기 관계식에 따라 상기 배터리의 SOH를 추정하는 BMS(Battery Management System)를 포함하고, 상기 배터리의 에너지 총량은 상기 배터리의 충전 에너지 및 방전 에너지의 합이다.
