The present invention relates to a method for regenerating a battery module based on a charge balance test. According to the present invention, the method for regenerating the battery module based on the charge balance test is conducted through a battery regeneration apparatus which regenerates a waste battery for a vehicle, which has been used for an environmentally-friendly vehicle, and which has been recovered. A battery module of the waste battery including the N number of battery cells is prepared, wherein N is a number equal to or greater than 2. A procedure is conducted to charge the battery module up to the designated maximum charge voltage through a module connection terminal connected to a power supply terminal of the battery module. When charging the battery module, the balance information is checked, which includes the difference in the charge voltage between the N battery cells placed in the battery module through the cell connection terminal connected to the cell terminal of the battery module. A balance test is conducted to determine whether the difference in the charge voltage between the N battery cells included in the balance information matches a preset charge voltage effective balance range. While keeping the status where the difference in the charge voltage between the N battery cells matches the preset charge voltage effective balance range, the charged battery module is discharged to the designated minimum discharge voltage. The N number of battery cells of the battery module, which are discharged to the designated minimum discharge voltage, are charged to the designated rated voltage for regeneration. The present invention aims to provide the method for regenerating a battery module based on a charge balance test, which is capable of providing a regenerated battery whose safety can be guaranteed for a certain period.
