Zusammenfassung:	Provided is a battery pack according to various embodiments of the present invention, which can extend the entire lifespan by normally using the battery pack without discarding the battery pack. The battery pack includes a battery, a DC/DC converter circuit, a switch circuit, and a controller. The battery includes first and second battery terminals, a plurality of battery cells electrically connected between the first and second battery terminals, and a plurality of cell switches respectively connected in series to the plurality of battery cells. The DC/DC converter circuit generates a cell replacement voltage from a battery voltage received through the first and second battery terminals and outputs the cell replacement voltage to the first and second cell terminals. The switch circuit is configured to connect two cell nodes positioned at both ends of a first battery cell selected from the plurality of battery cells to the first and second cell terminals, respectively. The controller controls the plurality of cell switches, the DC/DC converter circuit, and the switch circuit. 본 발명의 다양한 실시예에 따른 배터리 팩이 제공된다. 배터리 팩은 배터리, DC/DC 컨버터 회로, 스위치 회로 및 컨트롤러를 포함한다. 상기 배터리는 제1 및 제2 배터리 단자, 상기 제1 및 제2 배터리 단자 사이에 전기적으로 연결되는 복수의 배터리 셀, 및 상기 복수의 배터리 셀에 직렬로 각각 연결되는 복수의 셀 스위치를 포함한다. 상기 DC/DC 컨버터 회로는 상기 제1 및 제2 배터리 단자를 통해 수신되는 배터리 전압으로부터 셀 대체 전압을 생성하여 제1 및 제2 셀 단자로 출력한다. 상기 스위치 회로는 상기 복수의 배터리 셀 중에서 선택되는 제1 배터리 셀의 양단에 위치하는 2개의 셀 노드를 상기 제1 및 제2 셀 단자에 각각 연결하도록 구성된다. 상기 컨트롤러는 상기 복수의 셀 스위치, 상기 DC/DC 컨버터 회로, 및 상기 스위치 회로를 제어한다.
