본 발명의 일 실시예에 따른 배터리 SOH 추정 방법은, 배터리를 충전하는 기설정된 전압 범위에서 기설정된 전압간격별 충전 소요 시간의 측정치를 산출하는 단계, 기설정된 배터리 메타 모델에 의해 전압간격별 충전 소요 시간의 추정치를 산출하는 단계 및 상기 충전 소요 시간의 추정치가 반복적으로 충전 소요 시간의 측정치에 접근하도록 하여 상기 충전 소요 시간의 측정치와 상기 충전 소요 시간의 추정치의 오차가 가장 낮은 SOH(State Of Health)를 추정하는 단계를 포함한다.

    A method for estimating a state of health of a battery includes calculating a measured value of a charging required time for each of preset voltage intervals in a preset voltage range in which the battery is charged; calculating an estimated value of the charging required time for each of the voltage intervals by a preset battery meta-model; and estimating the SOH having lowest error between the measured value of the charging required time and the estimating value of the charging required time by allowing the estimated value of the charging required time to iteratively approach the measured value of the charging required time.
