Problems solved by technology

However, although this method can restore the capacity of the battery during use, the service life of the battery after recovery is very short.
This is because the large current and high voltage used in the pulse repair process have damaged the plates of the battery, causing the plates to deform, and the insulating partitions between the plates have also produced irreversible damage, resulting in insulation failure. Decreased performance directly shortens battery life
[0008] Although the above-mentioned repairing techniques can repair the lead-acid battery to a certain extent, they all have certain defects, which seriously affect the life of the battery. Therefore, it is urgent to design a new solution to effectively prevent the sulfuration of the lead-acid battery, thereby Extend battery life

Embodiment

[0039] This embodiment discloses a self-maintenance method for a lead-acid battery. By applying a charge-discharge pulse of a certain frequency to the battery, this charge-discharge pulse keeps the active material inside the battery in an activated state and can break the PbSO 4 Conditions for crystallization can prevent lead-acid batteries from vulcanization failure and prolong the service life of batteries.

[0040] The principle of self-maintenance of lead-acid batteries: sulfur ions have 5 different energy levels, and the ions in the metastable energy level tend to migrate to the stable covalent bond energy level. Sulfur in a stable covalent bond energy level exists in the form of a ring molecule containing 8 atoms. The 8-atom ring molecular mode is a relatively stable combination that is difficult to jump and be broken. PbSO 4 The sulfur atom in the crystal is in this stable energy level state. To break the structure of these sulfide layers, it is necessary to provide a...

Abstract

The invention discloses a maintenance device circuit structure and a lead-acid storage battery maintenance device. The maintenance device circuit structure comprises a power supply module, a detectionmodule, a signal indication module, a control module, a boost energy storage module, an electronic switch module and a DC / DC module. The maintenance device circuit structure has the beneficial effects that by utilizing the device, charging and discharging pulses with a certain frequency can be applied to the storage battery, and the charging and discharging pulses enable active substances in thestorage battery to be in an activated state all the time, and the conditions for generating PbSO4 crystals can be broken through, and the vulcanization failure of the lead-acid storage battery is prevented, and the service life of the storage battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery maintenance, in particular to a maintenance device circuit structure and a lead-acid battery maintenance device. Background technique [0002] The main reason for the vulcanization failure of the lead-acid battery is that the battery is in a static state for a long time, especially when the battery is discharged, and the active material on the battery plate is quickly sulfided and crystallized, resulting in coarse PbSO 4 crystals, leading to the failure of the active material. In order to prolong the service life of the battery, the following technologies are currently used to repair the vulcanized negative plate: [0003] 1. Shallow cycle high-current charging method. The mechanism of this method is to use the gas precipitated from the overcharged plate to wash away the sulfate formed by the slight sulfidation on the surface of the plate, so that it can be desorbed and dissolved and co...
