Lifetime prolonging and repairing device of lead-acid battery

Abstract

The invention discloses a lifetime prolonging and repairing device of a lead-acid battery. The device comprises a regulated power supply module, a single chip microcomputer control module, a frequency sweep pulse wave generation module, a battery state identification module and a photoelectric coupling module, wherein the single chip microcomputer control module is connected with the frequency sweep pulse wave generation module, the regulated power supply module, the battery state identification module, an LED signal display module and the photoelectric coupling module via a circuit separately; the frequency sweep pulse wave generation module can generate a low-medium frequency pulse wave and a medium-high frequency pulse wave for pulse treatment on a pole plate of the battery for various states of the lead-acid battery. The device can maintain the lead-acid storage battery through being connected to the lead-acid storage battery and can repair the waste lead-acid battery.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a life extension and repair device for lead-acid batteries. Background technique [0002] A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrodes is lead sulfate. The process of discharging and charging the lead-acid battery during use will cause sulfuration due to various reasons, which will greatly shorten the service life of the lead-acid battery. The main reason for sulfuration is that the self-discharge of the battery and the chemical reactions inside the battery will generate PbSO 4 crystal, so that the PbSO attached to the positive and negat...

AI Technical Summary

Problems solved by technology

Because the activity of metal elements such as Cu and Ag is very poor, CuS, Ag 2 S is difficult to separate by electrolysis, and has a stable molecular structure that is difficult to be broken, resulting in the encapsulated PbSO 4 Cannot be oxidized and reduced to Pb 2+ and SO4 2- The ions enter the electrolyte and react again

In the prior art, the maintenance and repair of lead-acid batteries is usually only aimed at the repair stage of the battery, resulting in the fact that the lead-acid battery cannot receive effective anti-sulfurization treatment during use, which affects the use of users

[0003] There is a lack of devices for continuous maintenance and repair of lead-acid batteries in the prior art, and the lead-acid battery repair devices in the prior art can only repair lead-acid batteries through pulse waves in a single frequency range, which can only break up a small part plate deposition, poor maintenance and repair effect

In addition, the lead-acid battery maintenance and repair device in the prior art cannot be used during battery use
