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.
