Charging device with maintenance and repair function

This is a charging device with the functions of maintenance and restoring. One end of the direct current charging control circuit of the charging device is connected with city current, and the other end is connected with storage battery; the charging device is characterized in that the above mentioned direct current charging control circuit is connected with the pulse signal generating circuit, which controls the high voltage current pulse circuit connected with the direct current charging control circuit. As equipped with the high voltage current pulse circuit and uses the pulse disturbing mode of high voltage current to charge electricity, the utility model can stimulate the inert materials inside the storage battery, such as the big crystal lead sulfate, convert the inert materials into reactive materials, and make the reactive materials keep on taking part in the electrochemical reaction. The utility model is provided with the vulcanizing function to storage battery. At the same time, this utility model can reduce the polarization voltage caused by chemical materials and some other reasons inside the battery, provide the charging device with polarization function, and charge the battery by 100%.
