Abstract
The invention discloses an acid pumping control technology of a container formation lead-acid storage battery, comprising the steps of: 1) allowing a storage battery after formation to stand for 1-3 h to make a pole plate and a separating plate to fully absorb acid, 2) charging for 1-3 h with a constant voltage and a limited current to dissolve free acid out, 3) then trickle charging, and 4) pumping away excess free acid by an acid pumping machine under the state of trickle charging after the amount of the dissolved acid liquid is not changed with time. The acid pumping control technology of the container formation lead-acid storage battery effectively balances the voltage stability of each circuit battery, completely eradicates the phenomenon of voltage fluctuation caused by different internal resistance of the battery during constant voltage charging, and also eliminates the battery acid leakage phenomenon.
Description
Technical field
The present invention relates to a kind of be internalized into lead acid accumulator take out sour Controlling Technology.
Background technology
Being internalized into lead acid accumulator is all adopt the mode of quantitative rich solution to carry out Battery formation, in the latter stage of battery charging, unnecessary free acid be proposed, with the generation preventing battery from leaking sour phenomenon.Because lead-acid battery uses under lean solution state, free acid is once excessive, Lou sour phenomenon will be caused, therefore each producer is all very strict to the control of free acid, but along with the increase of cycle-index, the continuous dehydration of inside battery (reason has: (2) (1) sealing reaction efficiency is low moulds the (3) self discharge of volatilizing of shell micropore and cause (4) long-term floating charge), when percentage of water loss is greater than 15%, battery life is about to come to an end maybe needs the maintenance that adds water.What therefore the interior acid of battery was measured has been controlled to dilemmatic thing, and acid was measured and leaked acid at most, and acid amount is very few causes series of problems, reduction cycle life, and has the hidden danger of thermal runaway.
Summary of the invention
Problem to be solved by this invention be to provide a kind of be internalized into lead acid accumulator take out sour Controlling Technology, simplify and take out sour program, effectively ensure that the even saturation of acid inhaled by dividing plate, maximize and improve effective acid content in battery and uniformity consistency, extending battery life.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of be internalized into lead acid accumulator take out sour Controlling Technology, comprise the following steps: 1) first the storage battery changing into end is left standstill 1-3h and allow pole plate and dividing plate fully absorb acid solution, 2) modified constant-voltage charge 1-3h allows free acid more than needed separate out again, 3) then trickle charge is carried out, 4) acid solution separated out can not because of the length in charging interval generating capacity change after, under trickle charge state, take unnecessary free acid away with taking out sour machine.
Improve, in modified constant-voltage charge technique, voltage sets is the mono-lattice of 2.46V/, current settings is 0.0125C
2.
Improve, in trickle charge process, current settings is 0.0125C
2.
Improve, described in take out sour machine negative pressure of vacuum be-0.06 ~-0.1MPa.
Beneficial effect:
After adopting technique scheme, this invention is a kind of be internalized into lead acid accumulator take out sour Controlling Technology, the voltage of active balance each loop battery is steady, stop battery when constant voltage charge takes out acid and caused the phenomenon of voltage levels injustice because internal resistance is different, also stop the seepage acid phenomenon of battery simultaneously.
Embodiment
A kind of be internalized into lead acid accumulator take out sour Controlling Technology, comprise the following steps: 1) first the storage battery changing into end is left standstill 1-3h and allow pole plate and dividing plate fully absorb acid solution, 2) modified constant-voltage charge 1-3h allows free acid more than needed separate out again, 3) then trickle charge is carried out, 4) acid solution separated out can not because of the length in charging interval generating capacity change after, under trickle charge state, take unnecessary free acid away with taking out sour machine.In modified constant-voltage charge technique, voltage sets is the mono-lattice of 2.46V/, current settings is 0.0125C
2, in trickle charge process, current settings is 0.0125C
2, 0.0125C
2be 0.0125 times of electric current of 2 hour rate rated capacities, described in take out sour machine negative pressure of vacuum be-0.06 ~-0.1MPa.
Technical scheme of the present invention adopts two step method to take out sour technique, simplifies and takes out sour program, effectively ensure that the even saturation of acid inhaled by dividing plate, maximizedly improves effective acid content in battery and uniformity consistency.Thoroughly stop battery when constant voltage charge takes out acid and caused the phenomenon of voltage levels injustice because internal resistance is different, effectively improve the uniformity consistency of battery acid content.
Except above preferred embodiment, the present invention also has other execution mode, and those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
