A plurality of driving circuits drive a plurality of contactors connecting a battery pack to an external device, on the basis of supply voltage, respectively. A processing circuit controls the plurality of driving circuits to successively close the plurality of contactors in a predetermined order, and before each of the contactors is closed, inspects the supply voltage thereof. Accordingly, it is possible to prevent an error in which a contactor does not close due to insufficient supply voltage of the contactor.
복수의 구동 회로가 공급 전압에 기초해서 배터리 팩과 외부 장치를 연결하는 복수의 컨택터를 각각 구동한다. 처리 회로는 복수의 구동 회로를 제어하여 복수의 컨택터를 소정의 순서대로 차례로 닫으며, 각 컨택터를 닫기 전에 공급 전압을 검사한다.
