The present invention provides a voltage equalization device which includes a diagnostic function for a battery module and is portable. The voltage equalization device comprises: first, second, and third connection terminals connected to a positive electrode of a first battery module, a positive electrode of a second battery module, and negative electrodes of the first and second battery modules, respectively; a balance circuit connected between the first and second connection terminals to form a current path between the first and second connection terminals; a first indicator circuit of which a display state is changed in accordance with difference voltage between the first and second connection terminals; a first comparator outputting output voltage differently in accordance with input voltage inputted in proportion to the voltage between the first and third connection terminals; and a second indicator circuit of which a display state is changed in accordance with the output voltage of the first comparator.

    전압 평형 장치는, 제1배터리 모듈의 양극, 상기 제2배터리 모듈의 양극, 및 상기 제1 및 제2배터리 모듈의 음극에 각각 연결되는 제1, 제2 및 제3연결 단자, 상기 제1 및 제2연결 단자 사이에 연결되어, 상기 제1 및 제2연결 단자 사이의 전류 경로를 형성하는 평형 회로, 상기 제1 및 제2연결 단자 사이의 차 전압에 따라 표시 상태가 변경되는 제1인디케이터 회로, 상기 제1 및 제3연결 단자 사이의 전압에 비례하여 입력되는 입력 전압에 따라, 출력 전압을 다르게 출력하는 제1비교기, 및 상기 제1비교기의 출력 전압에 따라서 표시 상태가 변경되는 제2인디케이터 회로를 포함할 수 있다.
