Problems solved by technology

The lead battery regeneration method in the prior art has the following defects: one is that the large particles of lead sulfate that have lost electrochemical activity in the lead battery have no repair ability; It is not easy to be reduced to lead sulfate, that is, it is difficult to discharge completely; the third is that the structure of the electric furnace wire under the handle is unreasonable, and the heat dissipation capacity is poor; the fourth is that it is impossible to observe the discharge depth, the remaining large particles of lead sulfate and the large Particulate lead dioxide will accelerate the aging of lead batteries, so it is difficult to greatly prolong the life of lead batteries being processed
However, there are still some misunderstandings about the use of lead batteries in theory and industry today. For example, charging must have a "float charge stage", and the discharge voltage of a single lead battery cannot be lower than 1.75V, etc.

Embodiment 1

[0060] On April 20, 2009, one of the creators of the Japanese invention bought an electric car. According to the structure and working principle of the aforementioned lead-acid batteries, we insist on "charging as you use it". In October 2012, it was found that the mileage of electric vehicles was significantly shortened, which could no longer meet the needs of daily work. Utilize the present invention, carried out the first " regeneration process " to electric vehicle lead battery, concrete operation is as follows:

[0061] (1) Insert the lead battery plug 21 into the charging socket of the lead battery of the electric vehicle, and insert the switching plug 22 into the interface E where the resistance wire resistance of the lead battery connected to the lead battery is the maximum resistance value, so that the lead battery connected to the lead battery The load is the maximum value;

[0062] (2) Turn on the discharge switch to discharge the battery through the resistance wi...

Embodiment 2

[0067] On August 7, 2014, it was found that the mileage of electric vehicles could not meet the needs of daily work again. Looking at the records, it was found that the lead battery of the experimental electric vehicle had been used for another year and 10 months. Therefore, the second "regeneration treatment" was carried out on the lead battery of the electric vehicle. The specific operation method was basically the same as the first time, until the indicator light could not be illuminated at all, and then the lead battery was charged at a constant voltage until it was fully charged. The connection of the charger, it is found that the mileage of the electric vehicle is not lower than that of Example 1.

Embodiment 3

[0069] On August 14, 2014, the emergency lights in the corridor of the chemical experiment building of Luoyang Normal University were inspected by the fire department and found to have lost their emergency safety value, and they were required to replace them all. Considering that the emergency lights in the corridor have only occasional short-term power outages in its history and have been in a charging state for a long time, the lead batteries must be in state I. For this reason, after it is pulled down, it has been regenerated with the present invention, and it is found that the treated emergency lighting lamp can fully meet the requirements of the fire department. Approved by the fire department, it was installed and used again.

[0070] The invention has the advantages of simple structure, relatively loose operating conditions and relatively low production cost, and the vast number of electric vehicle users can completely operate independently. It has a good regenerative ...

Abstract

The invention relates to the electrical energy storage field, and concretely relates to a lead storage battery regeneration apparatus and a regeneration method thereof. The apparatus adopts a resistance-variable resistance wire provided with an indicating lamp, and the resistance can be changed as needed to completely discharge a lead battery and can effectively avoid the generation of large granule lead sulfate caused by difficult reduction of large granule lead dioxide to lead sulfate due to small discharge current in the later stage of discharge; and the discharge depth can be momentarily observed through the indicating lamp to effectively avoid the sulfate formation of the lead battery and greatly prolong the life of the processed lead battery. The lead storage battery regeneration method has the advantages of non-strict operating conditions, simplicity, use convenience, and realization of good regeneration ability and multiplied service life of the processed lead battery.

Description

technical field [0001] The invention relates to the field of electric energy storage, in particular to a lead storage battery regeneration device and a regeneration method. Background technique [0002] Among secondary power sources, lead-acid batteries, hereinafter referred to as lead-acid batteries, account for more than 85% of the market share, and more than 95% of the electric energy storage does not contain fuel cells, and the abundance of the elements involved in the raw materials required for them is average on the earth. much higher than lithium. With the development of communication, photovoltaic industry, navigation, and public transportation, the consumption of lead batteries will further increase. However, the reality is that the service life of lead batteries is generally 2 to 3 years, and the maximum is no more than 4 years. The lead battery regeneration method in the prior art has the following defects: one is that the large particles of lead sulfate that ha...
