The lead sulfide crystallization on the battery plate can be removed. New crystallization can be further prevented from being generated. Already existing lead sulfide crystallization can be further converted into fine crystal grains. A dysfunctional or damaged battery can be repaired or the failure or damage of the battery can be delayed. The service lifetime of the battery is prolonged. The battery using cost is lowered.
Description
Technical field
The utility model relates to a kind of lead-acid battery charging device.
Background technology
The lead acid accumulator charging and discharging process is the process of electrochemical reaction, and lead sulfate becomes lead oxide during charging, and lead oxide is reduced to lead sulfate again during discharge.Lead sulfate is a kind of material of very easy crystallization, will form small crystals when the lead sulfate excessive concentration in the storage battery electrolytic solution or static standby time are long, the lead sulfate around these small crystalss attract again will form big inertia crystal as snowball.Lead sulfate after the crystallization not only can not restore into lead oxide when charging, also can precipitate to be attached on the electrode pad, causes the electrode pad work area to reduce, and this phenomenon is called the battery sulfuration, and at this moment the capacity of storage battery can reduce gradually, until using.Also can attract plumbous particulate to form plumbous branch when the lead sulfate bulk deposition, the plumbous branch bridging between the positive/negative plate can cause the storage battery short circuit.If polar board surface or mould shell the slit is arranged, the lead sulfate crystallization will be piled up in these slits and be produced expansive force, finally makes pole plate fracture or outer casing rupture, the damage that causes battery to repair, so the dominant mechanism that causes battery failure and damage is the unavoidable sulfuration of battery itself.
If can postpone the inefficacy of battery or avoid it to damage, perhaps the battery reparation of thoroughly not losing efficacy or damaging just can significantly can be reduced the battery use cost.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of lead-acid battery charging device.
Charging device of the present utility model comprises:
1. charging current generating means is for generation of the high frequency DC pulse charging current that battery is charged;
2. checkout gear is for detection of the output situation of charging current generating means;
3. control device is used for the detection information according to the above-mentioned detection device acquisition, adjusts the charging current output of above-mentioned charging current generating means, makes it keep stable.
Device output high frequency DC pulse charging current of the present utility model, lead acid accumulator is charged, can remove the vulcanized lead crystallization on the accumulator plate, and prevent the formation of new crystallization, and can also make existing vulcanized lead crystallization turn to small grains, these tiny crystal grain can participate in the electrochemical reaction that discharges and recharges normally, have solved the problem that vulcanized lead adheres at battery pole plates.So, just can repair the battery that lost efficacy or damage, perhaps postpone inefficacy or the damage of battery, thereby prolong battery service time, the conserve batteries use cost.
