차량용 배터리 시스템 및 배터리 충전 제어 방법이 개시된다. 상기 차량용 배터리 시스템은, 서로 직렬 연결된 복수의 배터리셀을 갖는 제1 배터리모듈; 서로 직렬 연결된 복수의 배터리셀을 가지며 상기 제1 배터리모듈과 직렬연결된 제2 배터리모듈; 및 상기 제1 및 제2 배터리모듈 각각의 충전상태를 감시하고, 상기 제1 및 제2 배터리모듈 중 하나의 충전상태가 기설정된 레벨 이하인 경우, 상기 제1 배터리모듈의 배터리셀과 상기 제2 배터리모듈의 배터리셀 사이에 액티브 셀밸런싱을 실시하는 컨트롤러;를 포함한다.
A vehicle battery system and a method of controlling charge of a battery in the system are provided. The system includes a first battery module that has a plurality of battery cells connected to each other in series and a second battery module that has a plurality of battery cells connected to each other in series. The second battery module is connected to the first battery module in series. A controller then monitors a state of charge of each of the first and second battery modules, such that when the state of charge of one of the first and second battery modules is less than a predetermined level, the controller performs active cell balancing between the battery cells of the first battery module and the battery cells of the second battery module.
