The present invention relates to a zero voltage charge/discharge circuit using a diode module. In particular, the present invention includes a battery; a charge/discharge driving circuit which charges or discharges the battery; and a voltage dropping means which is installed between the charge/discharge driving circuit and the battery to generate different voltage drops for charging or discharging the battery in order to discharge the battery to a zero voltage. The voltage dropping means includes a discharge voltage dropping means which connects an auxiliary power supply to the battery in series and discharges the battery even in an area where the voltage of the battery is lower than a set voltage during a discharge operation; and a conduction prevention means which prevents conduction in the auxiliary power supply through the diode module during a charge operation. As a result, it is possible to discharge the battery to a zero or near-zero voltage during the discharge of the battery. |
