Technical Field
The invention relates to the technical field of formation charging in lead-acid storage batteries, in particular to the technical field of a novel efficient positive and negative pulse charging process.
Background
The traditional lead-acid storage battery industry adopts a constant-current constant-voltage mode to carry out container formation charging, and the traditional formation charging time is as long as more than 65 hours. The traditional container formation charging process has low charging efficiency, low oxidation reaction rate inside the battery, large heat productivity of the battery and incomplete formation of a polar plate. The main reason for this phenomenon is that during the formation process in the battery, the polar plate generates polarization phenomenon in the later stage of charging, resulting in a large amount of electricity to electrolyze water and generate a large amount of heat. And a large amount of acid mist is generated, which causes environmental pollution.
The formation heating in the battery is too large, a large amount of external cooling water is needed for cooling, and a large amount of manpower and material resources are consumed; the traditional container formation time is too long, and the production efficiency and the turnover of production equipment are seriously influenced.
Disclosure of Invention

step 6, positive and negative pulse charging: a positive pulse and negative pulse charging mode is adopted, the charging time is 4 hours, and the main purpose is to perform depolarization processing on the battery; the polarization state of the polar plate can be greatly reduced through the charging process of the step, so that the charging efficiency is improved;
step 7, positive pulse charging: a positive pulse charging mode is adopted, the charging time is 6h, and the complete formation of the battery is completed by adopting efficient positive pulse charging after the 6 th step of depolarization;
step 8, constant voltage charging: the battery is charged for 1h by adopting a charging mode of a single battery with a constant voltage of 14.8V, so as to ensure the consistency of the battery after formation;
step 9, cutting off the power and absorbing acid: the total process time is 23h20min (excluding power-off acid absorption time).
The invention has the following beneficial effects:
1. the invention has simple structure, changes the traditional constant-current charge-discharge container formation mode into positive and negative pulse type according to the basic principle of J.A.Mas law, and compared with the traditional container formation process, the new container formation charging process of positive and negative pulses reduces polarization, improves the current utilization rate, improves the efficiency of redox reaction, reduces side reaction, improves the container formation efficiency, reduces the emission of acid mist and shortens the production period of products.
2. The pulse container formation charging process mainly solves the problems that the positive plate is activated to save electric energy, the charging time is shortened to 23 hours, the production efficiency is improved, the production field is saved, and charging related facilities are saved.

Detailed Description
The following examples further describe the invention in detail in order that those skilled in the art may better understand the invention.
Example 1
As shown in fig. 1, the embodiment provides a novel efficient positive-negative pulse charging process, which includes the following steps:
step 1, adding acid for charging: the acid adding mode of the novel charging process for the battery is consistent with that of the traditional charging process;
step 2, constant current charging: the traditional constant current charging is adopted for 5 hours;
step 3, positive intermittent pulse charging: a positive intermittent pulse charging mode is adopted, and the charging time is 3 hours;
step 4, stopping charging: standing for 20 min;
step 5, a positive intermittent pulse charging mode: the process flow adopts a positive intermittent pulse charging mode, and the charging time is 4 h;
step 6, positive and negative pulse charging: a positive pulse and negative pulse charging mode is adopted, the charging time is 4 hours, and the main purpose is to perform depolarization processing on the battery; the polarization state of the polar plate can be greatly reduced through the charging process of the step, so that the charging efficiency is improved;
step 7, positive pulse charging: a positive pulse charging mode is adopted, the charging time is 6h, and the complete formation of the battery is completed by adopting efficient positive pulse charging after the 6 th step of depolarization;
step 8, constant voltage charging: the battery is charged for 1h by adopting a charging mode of a single battery with a constant voltage of 14.8V, so as to ensure the consistency of the battery after formation;
step 9, cutting off the power and absorbing acid: the total process time is 23h20min (excluding power-off acid absorption time).
In the embodiment, chemical energy is converted into electric energy by adopting positive intermittent pulse and positive and negative pulse charging. Through theoretical analysis and multiple experimental summaries, we adopt a staged constant-current pulse charging mode, and the pulse stage charging process is as follows: the cycle process of positive pulse charging, stopping charging, positive pulse charging, negative pulse discharging, stopping discharging and positive pulse charging is carried out. As charging progresses, the charging current decreases from stage to stage. This charging method allows the charging curve to generally approximate the acceptable charging current curve of the battery proposed by gauss.
The total process time is 23h20min (excluding the power-off and acid-absorption time), and the pulse container formation charging process mainly solves the problems of saving electric energy by activating the positive plate, shortening the charging time to 23h, improving the production efficiency, saving the production field and saving related charging facilities. The time of internalization is greatly shortened on the basis of reducing the time of charging for long time of internalization, the electric quantity of charging is reduced, and the power consumption is saved.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, the scope of the present invention is defined by the appended claims, and all equivalent changes made by applying the contents of the description of the present invention should be embraced in the scope of the present invention.
