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.

    The present disclosure relates to a method for estimating a state of health (SOH) of a battery and a battery system providing the same. According to the present disclosure, the battery system includes: a battery; and a battery management system (BMS) configured to obtain degradation conditions related to degradation of the battery at each predetermined monitoring cycle, determine a relational expression representing a relationship between a total energy amount of the battery and a state of health (SOH) of the battery according to the degradation conditions at the each monitoring cycle, and estimate an SOH of the battery according to the relational expression, wherein the total energy amount of the battery is the sum of charge energy and discharge energy of the battery.
