본 발명은 전기 자동차의 배터리 충전 방법에 관한 것으로, 전기 자동차의 배터리 충전 시 충전 속도를 개선하면서 배터리의 열화는 방지하는데 그 목적이 있다. 이를 위해 본 발명에 따른 배터리 충전 방법은, 배터리의 전체 SOC 구간을 복수의 스텝으로 나누고 상기 복수의 스텝마다 정전류 방식의 충전을 실시하는 단계와; 상기 복수의 스텝마다 상기 정전류 방식의 충전을 실시하는 사이에 미리 설정된 전압으로 정전압 방식의 충전을 실시하는 단계를 포함한다.

    The present disclosure provides methods for charging a battery of an electric vehicle, which relates to a technology for preventing deterioration of a battery embedded in an electric vehicle while simultaneously improving a charging speed of the battery. The battery charging method includes dividing a total State of Charge (SOC) section of a battery into a plurality of steps, and performing constant current based charging in each of the plurality of steps, and performing constant voltage-based charging at a predetermined voltage during the constant current based charging for each step of the plurality of steps.
