The present invention is a balancing technology of a battery management system (BMS) for a plurality of battery cells in a battery pack. The technology prevents fire and maintains durability of a battery pack by adjusting a voltage difference between battery cells, wherein the voltage difference may occur between the plurality of battery cells during a process of charging the battery pack or discharging the battery pack. According to the present invention, by having a plurality of OP amplifier members, it is possible to exclude adoption of a plurality of cell balancing controllers installed in the conventional BMS controller so that there is an advantage of lowering manufacturing costs of the BMS controller.

    본 발명은 배터리 팩 내의 복수 개 배터리 셀에 대한 BMS(battery management system)의 밸런싱 기술로서, 배터리 팩을 충전하거나 그 배터리 팩이 방전되는 과정에서 복수의 배터리 셀 간에 전압 편차가 발생할 수 있는데, 그 배터리 셀 간의 전압 편차를 조절함에 따라 배터리 팩의 화재 예방이나 내구성을 유지하도록 하는 기술이다. 본 발명에 따르면 복수의 OP앰프 부재를 구비함에 따라 종래의 BMS 제어기에 구비되는 복수의 셀 밸런싱 제어기 채택을 배제할 수 있으므로 BMS 제어기의 제작 단가를 낮출 수 있는 장점이 있다.
