Abstract

The undamaged repair device for large-capacity sealing lead-acid cell comprises: a SCM-control treatment circuit (1) to output waveform width modulation impulse according to detected the voltage and temperature data of target cell, a PWM waveform shaping drive circuit (2) to control following switch (3) and repair impulse current, a controlled electronic switch (3), and a dc power circuit (6) to supply dc to said switch (3) to transform into impulse current for target cell (7). This invention improves repair efficiency and has wide application.

Description

technical field [0001] The invention relates to a repairing device for removing lead sulfate crystals inside the pole plate of a lead-acid storage battery by using an electronic pulse method to restore battery capacity, in particular to a non-destructive repairing device for a large-capacity sealed lead-acid storage battery. Background technique [0002] The use of lead-acid batteries is very common, such as lead-acid batteries used in lead-acid battery production plants, mines, automobile maintenance and other departments, due to the influence of climate, frequent power outages and insufficient charging of batteries and long-term standby status , A thick and hard lead sulfate crystal will gradually be formed inside the battery plate, which will block the spongy Pb micropores of the negative plate, hinder the mutual conversion of electrical energy and chemical energy, and cause the battery capacity to gradually decrease or even be scrapped. At present, the use of electronic ...
