Abstract
The invention relates to the field of lead acid storage batteries, and in particular relates to a method for improving the group consistency of a lead-acid storage battery. The method comprises the following step of: in the formation process, drawing out air in the battery before the acid is drawn out. By adopting the method, the difference of acid content in the battery can be reduced, and the consistency of the batteries in a group is guaranteed.
Description
Technical field
The present invention relates to lead-acid accumulator field, particularly relate to a kind of raising lead-acid accumulator conforming method in groups.
Background technology
Lead-acid accumulator is with pure dilute sulfuric acid as electrolyte, and reaction equation is: PbO2+2H2SO4+Pb==2PbSO4+2H2O.Acid ratio is heavily typically between 1.2 ~ 1.3g/ml, and the Main Function of electrolyte is the temperature when chemical reaction on participation pole plate, conducting ion and reduction cell reaction.Generally, the capacity of battery increases with the concentration of electrolyte, the increase of content.The electricity that lead-acid battery is filled with in formation process is 9-11 times of design ampere-hour, particularly it is melted into the later stage, have substantial amounts of gas to come up, after chemical conversion terminates, when taking out acid, owing to the gas flow of inside battery is inconsistent, can cause when taking out acid that the electrolyte extracted amount inside battery is inconsistent, causing that acid content is inconsistent, single lattice can also exist 5-10ml difference, thus causing that the capacity of battery changes.Such as: the large current charge scope of compacted accumulator is at 3A-5A, the large current charge electric current of large density battery reaches 10A-20A, 12V cell voltage can be charged to 17V, during chemical conversion, electric current is big, voltage is high, the time is long, the gas flow produced is big, causes acid solution uneven in the battery and the diversity of acid solution between battery. and battery there will be simple substance and falls behind situation generation under circulating at this.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of raising lead-acid battery conforming method in groups.Operational approach of the present invention, it is possible to reduce the difference of acid content in battery, it is ensured that battery concordance in groups.
The present invention comprises the following steps: be internalized in process, adds the step of the air extracted out in battery before taking out acid.
Further, extracting the air in battery out, in battery, the scope of negative pressure is between-0.025 to-0.05mpa.
Further, the air in battery is extracted out by negative tube.
Further, battery, under constant current or constant voltage, carries out taking out acid for 2-3 hour.
Further, the electric current of constant current 0.1-0.2A, the voltage of constant voltage 15.9-16.10V
Present invention can ensure that battery concordance in groups, extend the service life of battery.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
The green plate of lead-acid battery is after completing, it is necessary to be internalized into, and namely the pole plate being arranged in battery is electrochemically reacted.After electrochemical reaction, there is unnecessary acid solution in inside battery, need to extract unnecessary acid solution out, the present invention is after battery rich solution is internalized into reaction, extract the conduit inside acid adding kettle out, then with negative tube, battery being taken out negative pressure, it is ensured that the concordance of inside battery negative pressure, the scope of negative pressure is preferably controlled in-0.025 ~-0.05mpa.After air inside battery is exhausted, with the electric current of constant current 0.1 ~ 0.2A or mono-12v battery of constant voltage 15.90-16.10V(), 2-3 hour time carried out taking out acid, it is drawn out of due to inside battery air and pressure keeps consistent, take out under acid condition identical, the inconsistent of acid amount will not be taken out because of inconsistent the causing of internal pressure, thus ensure that the concordance of inside battery acid solution, then combo electric discharge is carried out, ensure that the verity of the capacity of battery, be conducive to the groups of concordance of battery, avoid single inside the Battery pack service life fallen behind and affect battery.
Claims (5)
