Background technology
At present, lead acid accumulator commonly used in use, the charge and discharge process can produce following reaction:
Lead acid accumulator is when discharge, and it is lead sulfate that positive/negative plate all produces a kind of compound.Lead sulfate is a kind of water that is insoluble in, nonconducting material, and under normal circumstances, the lead sulfate crystallization that storage battery forms after discharge is smaller, during charging, under the effect of electric energy, than being easier to dissolving and being reduced into lead.If but improper use, as: undercharge, dehydration, overdischarge etc., lead sulfate will form thick hard crystalline solid, at this moment just is difficult to general method it is reduced into lead, so be referred to as irreversible sulfation.Because sulfation, on the one hand, it can stop that sulfuric acid contacts with other active materials and reacts; On the other hand, quantity of active material is reduced, it can cause that battery capacity descends, and can cause the life of storage battery to stop when serious.
The Another reason that causes battery to damage is that active material comes off, and the active material reason that comes off has following several explanation: 1, battery is subjected to the influence of external force, as vibration, beats etc.2, α-PbO
2And β-PbO
2Ratio changes.α-PbO
2Be the active material skeleton, when battery when discharging and recharging, a part of α-PbO
2Be converted into β-PbO
2Thereby cause softening and shedding.3, along with circulation is carried out, active material is by indefiniteness attitude crystal formationization gradually, and promptly degree of crystallinity increases, hydrated polymer chain decreased number, and the gel piezoresistance increases, and intercrystalline electrically contacts deterioration, and this active material comes off.4, the somebody thinks, along with constantly carrying out of charging and discharge, active material forms some intensive agglomerates, and when lacking enough connections between agglomerate, active material will come off, battery failure.According to the work characteristics of battery, safeguard reasonably and use that the prolongation of battery life is had extremely important meaning.Lead acid batteries charger is generally all taked the first constant current mode of constant voltage charge more at present, but the function that this charging modes does not have battery to repair.
Summary of the invention

When lead acid battery charge, the high-frequency impulse that the Single-chip Controlling pulse generator produces, the power switch pipe of forming by transistor is connected in parallel on accumulator anode and cathode by inductance, make battery-operated under the state of pulse current charge, voltage changer is transformed into single-chip microcomputer and the required operating voltage of pulse generator with the output voltage of charger, because the I/O mouth of single-chip microcomputer connects the control end of pulse generator, adopt the high-frequency impulse technology, in the lead-acid battery charging, constantly produce variable-frequency pulse, reach effect the online reparation of lead-acid battery by Single-chip Controlling.Single-chip microcomputer can adopt the reparation pulse of different frequency according to battery electrochemical mechanism in the different phase (incipient stage, interstage and charging later stage) of charging, thereby reach best repairing effect as the control core.The required energy of prosthetic device comes from the energy of charger.
The utility model adopts the high-frequency impulse technology, constantly produces variable-frequency pulse by Single-chip Controlling in charging, resonates with lead sulfate crystalline solid in the battery, thereby makes the lead sulfate crystal be reduced into sulphion and lead ion, adjusting α-PbO
2And β-PbO
2Ratio to rational proportion, change dielectric composition and character, fully discharge and activate former active material, make it possess stronger electrochemistry ability, reduce the internal resistance of cell, thoroughly eliminate the battery sulfation.This method is used for new accumulator and is using the charging of storage battery, then can make its delaying aging and recovery capacity respectively, keeps optimum state.
The utility model has the advantages that:
1. can in charging process, clear away pole plate agglomerate on every side by launching the ion that constantly transforms between the both positive and negative polarity termly;
2. powerful negative pulse can smash thick hard lead sulfate crystallization and impel its dissolving;
3. regulate by duty of ratio and make α-PbO
2And β-PbO
2Ratio more become reasonable;
