Abstract:
An apparatus for charging and discharging a battery device having positive and negative terminals, comprising:a power supplying unit operable so as to provide a direct current voltage output;a current control unit coupled to said power supplying unit so as to receive the direct current voltage output therefrom; anda control device coupled to said current control unit and adapted to be coupled to the battery device, said control device enabling said current control unit when a battery voltage of the battery device is below a predetermined voltage value, and disabling said current control unit when the battery voltage is at least equal to the predetermined voltage value;said current control unit being adapted to be coupled to the battery device in a charging state, where the positive terminal of the battery device is coupled to said current control unit so as to permit charging of the battery device when said current control unit is enabled by said control device;said current control unit being further adapted to be coupled to the battery device in a discharging state, where the negative terminal of the battery device is coupled to said current control unit so as to permit discharging of the battery device when said current control unit is enabled by said control device.
