description According to an embodiment of the present invention, an overcharge prevention apparatus using a potential difference between battery modules includes: a first battery module; a second battery module of which the number of stacked cells are different from that of the first battery module; a subtractor calculating a power difference value according to first power of the first battery module and second power of the second battery module; an electric current application switch comparing the power difference value and a preset reference value, and switched on according to the comparison result; a fuse allowing power to flow from external power, and provided with the power from the first battery module and the second battery module according to the switching on and carpeted under preset certain constant power; and a main switch turned off when the fuse is melt. 본 발명의 일실시예에 따른 배터리 모듈간 전위차를 이용한 과충전 방지 장치는, 제 1 배터리 모듈; 상기 제 1 배터리 모듈과 배터리 셀 적층수가 다른 제 2 배터리 모듈; 상기 제 1 배터리 모듈의 제 1 전원과 제 2 배터리 모듈의 제 2 전원에 따른 전원 차이값을 계산하는 감산기; 상기 전원 차이값과 미리 설정된 기준값을 비교하여, 비교 결과에 따라 스위칭온되는 통전 스위치; 외부 전원으로부터 전원을 흐르게 하며, 상기 스위칭 온에 따라 상기 제 1 배터리 모듈 및 제 2 배터리 모듈로부터 전원을 공급받아 미리 설정된 일정 전원의 조건하에서 융단되는 퓨즈; 및 상기 퓨즈가 융단됨에 따라 오프되는 메인 스위치;를 포함하는 것을 특징으로 할 수 있다.
