More Information
Summary:According to one embodiment disclosed in the document, a battery management apparatus may include: a plurality of balancing resistors connected to each of a plurality of battery cells; a common resistor connected to the plurality of balancing resistors in parallel; a plurality of resistance switches connected between the plurality of balancing resistors and the common resistor; and a control unit calculating a balancing time of the plurality of battery cells and controlling an operation of the plurality of resistance switches based on the balancing time. 본 문서에 개시된 일 실시예에 따른 배터리 관리 장치는 복수의 배터리 셀들 각각에 연결되는 복수의 밸런싱 저항들, 상기 복수의 밸런싱 저항들과 병렬 연결되는 공통 저항, 상기 복수의 밸런싱 저항들과 상기 공통 저항 사이에 연결되는 복수의 저항 스위치들, 및 상기 복수의 배터리 셀들의 밸런싱 타임을 산출하고, 상기 밸런싱 타임에 기초하여 상기 복수의 저항 스위치들의 동작을 제어하는 제어부를 포함할 수 있다.
