Storage battery recycling apparatus

摘要

Disclosed herein is a storage battery recycling apparatus in which a pulse current is applied to polar plates or electrodes of a storage battery functioning as a secondary cell through the SCR phase control so as to remove sulfate formed in a film or membrane on the electrodes of the storage battery, thereby recovering the performance of the storage battery in a deteriorated state. The inventive storage battery recycling apparatus includes: a transformer unit 200 for transforming a commercial AC power voltage supplied thereto from an external power source through a power input unit 100; an SCR driving unit 400 for converting the AC power voltage transformed by the transformer unit 200 into a voltage having a pulse waveform through the SCR phase control; an output terminal 500 adapted to be in close contact with the electrodes of the storage battery for supplying the converted pulse voltage outputted from the SCR driving unit 400 to the electrodes of the storage battery so as to charge the storage battery; an SCR controller 300 for controlling the operation of the SCR driving unit 400; a setting unit 600 and a display unit 650 for setting and displaying the operational environment of the storage battery recycling apparatus; a voltage detecting unit 900 and a current detecting unit 950 for detecting the voltage and current of the storage battery; and a microcomputer 700 for controlling the operation of each of the constituent elements.
