Abstract

본 발명의 일 실시예에 따른 배터리 관리 장치는 배터리의 용량 및 전압에 대한 배터리 정보를 획득하고, 상기 용량 및 상기 전압에 기반한 미분 전압과 상기 용량 간의 대응 관계를 나타내는 미분 프로파일을 생성하도록 구성된 프로파일 생성부; 및 상기 프로파일 생성부로부터 상기 미분 프로파일을 획득하고, 획득된 미분 프로파일에서 복수의 피크를 검출하며, 검출된 복수의 피크 각각에 대응되는 용량에 기반하여 상기 배터리의 퇴화도를 산출하고, 산출된 퇴화도와 미리 설정된 기준 퇴화도를 비교한 결과에 따라 상기 배터리에 대한 충전 종료 전압의 상한을 설정하도록 구성된 제어부를 포함한다.
