The present invention relates to a battery management method and a battery system providing the same, which can extend the life of a battery. The battery system according to the present invention comprises: a battery; and a BMS for controlling charging of the battery according to a normal mode which uses a first battery capacity between a first state of charge (SOC) lower limit and a first SOC upper limit or an eco-mode which uses a second battery capacity between a second SOC lower limit and a second SOC upper limit. The first SOC lower limit is smaller than the second SOC lower limit, and the first SOC upper limit is greater than the second SOC upper limit. According to the battery management system, when a user turns on the eco-mode, a usable battery capacity is reduced and the battery is charged in a slow charging method.

    본 발명은, 배터리의 수명을 연장할 수 있는 배터리 관리 방법 및 이를 제공하는 배터리 시스템에 관한 것으로, 본 발명에 따른 배터리 시스템은, 배터리, 그리고 제1 하한SOC(State of Charge)와 제1 상한SOC 사이의 제1 배터리 용량을 사용하는 노멀모드 또는 제2 하한SOC와 제2 상한SOC 사이의 제2 배터리 용량을 사용하는 에코모드에 따라 상기 배터리의 충전을 제어하는 BMS를 포함하고, 상기 제1 하한SOC는, 상기 제2 하한SOC 보다 작고, 상기 제1 상한SOC는, 상기 제2 상한SOC 보다 크다.
