An apparatus is adapted for charging and discharging a battery device having positive and negative terminals. The apparatus includes a power supplying unit operable so as to provide a direct current voltage output, a current control unit coupled to the power supplying unit so as to receive the direct current voltage output therefrom, and a control device coupled to the current control unit and adapted to be coupled to the battery device. The control device enables the current control unit when a battery voltage of the battery device is below a predetermined voltage value, and disables the current control unit when the battery voltage is at least equal to the predetermined voltage value. The current control unit is adapted to be coupled to the battery device in a charging state, where the positive terminal of the battery device is coupled to the current control unit so as to permit charging of the battery device when the current control unit is enabled by the control device. The current control unit is further adapted to be coupled to the battery device in a discharging state, where the negative terminal of the battery device is coupled to the current control unit so as to permit discharging of the battery device when the current control unit is enabled by the control device.
