Problems solved by technology

[0004] The reason for the sulfation phenomenon of the lead-acid battery plate is that after the normal battery is discharged, the active substances on the positive and negative plates mostly become small crystals of soft lead sulfate, which are evenly distributed in the plate, It is easy to return to the original lead dioxide and spongy lead when it is used. This is a normal sulfation. Due to improper use of the battery, long-term insufficient charging, or half-discharged state, excessive discharge or not charging in time after discharge, internal short circuit, The density of the electrolyte is too high, the temperature is hig

Embodiment 1

[0015] Example 1: Activation and restoration of each 12 volt, 100Ah waste lead-acid battery pack of a telecommunication base station backup battery pack, after testing, the lead-acid battery shell, pole, battery inner busbar, tabs, and grid It is good, the voltage rises rapidly during the charging process, and the voltage decreases rapidly during the discharging process. There are white lead sulfate spots on the surface of the polar plate. It is confirmed that the battery has a relatively high degree of vulcanization, but it is a recoverable lead-acid battery. The activator, activation current, and activation time to be added are calculated as follows:

[0016] The addition ratio of activator is 2-4ml / Ah, so the amount of 100Ah added is between 200ml-400ml, we choose 300ml activator to activate and restore the battery, because the 12-volt battery is divided into 6 slots, so each slot Need to inject 50ml of activation solution.

[0017] The activation currents are: because the...

Abstract

The invention applies technique of activation and recovery to lead acid battery by using activator and activating instrument. Having high frequency impulse power supply, the activating instrument can send out high frequency impulse in frequency identical to natural frequency of molecule of compound sulfuric acid. The invention solves technical difficulties of low degree of recovery if the activator and activating instrument is applied solely in prior art. The invention is mainly applied to activation and recovery for each sort of lead acid battery (set).

Description

technical field [0001] The invention belongs to the technical field of electricity, and relates to the restoration technology of a secondary battery, that is, a lead-acid storage battery. Background technique [0002] At present, there are two ways to restore and maintain lead-acid batteries in the world. One is American products (patent numbers: 4871959, 5084664, 5276393, 5491399), called pulse battery protectors, which rely on solar energy or batteries. The electricity generated by itself produces a DC pulse whose frequency is the same as the natural frequency of the sulfuric acid compound molecule of the battery, so resonance is generated, and the sulfuric acid compound, namely sulfate, is decomposed and separated from the battery plate, but its recovery degree is only 80% %; the second is the lead-acid battery activator developed by Japan Haotek Co., Ltd., which mainly decomposes sulfate through the activity of the added activator, so that it is separated from the batter...
