Abstract

배터리 팩은 배터리 셀 및 상기 배터리 셀을 위해 전력을 입출력하는 변압기를 내장한 셀 모듈을 복수 개 쌓아 연결하고, 복수 개 셀 모듈 각각의 변압기 외부측 연결단을 병렬로 연결한 셀 모듈 스택, 그리고 각 셀 모듈이 전송한 각 셀 모듈의 상태 정보를 기초로 기준 전압을 계산하고, 배터리 셀 전압이 기준 전압보다 높은 제1 셀 모듈로 내장 변압기를 통해 일부 전력을 출력하도록 제1 제어 신호를 전송하고, 배터리 셀 전압이 기준 전압보다 낮은 제2 셀 모듈로 내장된 변압기의 외부측 연결단에 인가된 전력을 배터리 셀로 공급하도록 제2 제어 신호를 전송하는 배터리 관리 시스템을 포함한다.
