Abstract: Provided are a charging/discharging apparatus, an operation method of the charging/discharging apparatus, and a display apparatus including the charging/discharging apparatus. The charging/discharging apparatus includes a charging unit comprising circuitry configured to charge a battery pack, and a direct current (DC)-DC converter configured to convert a battery voltage of the battery pack into a voltage for operating the display apparatus, wherein, in a first mode based on an alternating current (AC) power source being applied to the display apparatus, the charging/discharging apparatus charges the battery pack with a battery voltage less than a secondary voltage generated by the display apparatus from the AC power source through the charging unit, and in a second mode based on the AC power source not being applied to the display apparatus, the charging/discharging apparatus delivers the battery voltage of the battery pack to the display apparatus.
