The present invention relates to a battery pack and a control method thereof. The battery pack comprises: a plurality of battery cells; a plurality of cell controllers prepared to correspond to different parts of the plurality of battery cells and including a DC/DC converter to which a voltage of a corresponding battery cell is inputted; a first power circuit for receiving power from some battery cells of the plurality of battery cells without going through the DC/DC converter included in a cell controller corresponding to the corresponding battery cell to generate power for driving a battery pack; and a main control unit for controlling the plurality of cell controllers by using power of the first power circuit. Therefore, power can be stably supplied to a battery management system.

    본 발명은 배터리 팩 및 이의 제어방법에 관한 것으로, 복수의 배터리 셀, 복수의 배터리 셀 중 서로 다른 일부에 대응하여 마련되며, 대응하는 배터리 셀의 전압을 입력으로 하는 DC/DC 컨버터를 포함하는 복수의 셀 제어기, 복수의 배터리 셀 중 일부의 배터리 셀로부터 해당 배터리 셀에 대응하는 셀 제어기에 포함된 DC/DC 컨버터를 거치지 않고 전력을 공급받아 배터리 팩 구동용 전력을 생성하는 제1 전원 회로, 및 제1 전원 회로의 전력을 이용하여 복수의 셀 제어기를 제어하는 주 제어부를 포함하는 배터리 팩을 제공한다.
