According to an embodiment of the present invention, an operation method of a battery management system comprises the steps of: measuring a waiting time before starting charging of a battery; executing a first charging operation of charging the battery at a first C-rate when a state of charge (SOC) of the battery is less than or equal to a reference SOC and the waiting time is longer than a predetermined threshold time; and executing a second charging operation of charging the battery at a second C-rate greater than the first C-rate when the SOC of the battery reaches the reference SOC by the first charging operation, wherein the second C-rate is five times or more of the first C-rate.

    본 발명의 일 실시예에 따른 배터리 관리 시스템의 동작 방법은, 배터리에 대한 충전을 시작하기 이전에 대기 시간을 측정하는 단계, 상기 배터리의 SOC(State Of Charge)가 기준 SOC 이하이고 상기 대기 시간이 소정의 임계 시간보다 길면, 제1 C-Rate로 상기 배터리를 충전하는 제1 충전 동작을 실행하는 단계, 및 상기 제1 충전 동작에 의해 상기 배터리의 SOC가 상기 기준 SOC에 도달하면, 상기 제1 C-Rate보다 큰 제2 C-Rate로 상기 배터리를 충전하는 제2 충전 동작을 실행하는 단계를 포함하며, 상기 제2 C-Rate는 상기 제1 C-Rate의 5배 이상이다.
