Description
Technical field
The utility model relates to storage battery field, mainly a kind of pulsed lead acid accumulator maintenance instrument.
Background technology
Batteries in support power supply is widely used in electricity substation and communications equipment room.Because battery pack is that series connection uses, therefore, the performance of whole Battery pack is decided by the performance wherein differing from most a batteries.In battery pack running, first the decline of battery performance shows as minority cell performance degradation, and (as: float charge voltage is on the low side or higher, internal resistance increase etc., this phenomenon valve-control sealed lead acid battery shows particularly evident), and charger charges to whole Battery pack, performance difference between each battery cannot be taken into account, as processed behindhand battery not in time, discreteness between battery will be caused to strengthen, battery is caused to produce charge less, overcharge, sulfation, off-capacity, interior resistive is large, even bulge, the performance degradation phenomenons such as dry liquid, and this deterioration has autoacceleration trend, whole Battery pack is finally caused to lose efficacy.
The reason causing battery performance to decline is a lot, and the form of expression and processing method are also different.The battery on the low side for a long time for float charge voltage can supplement electricity separately online; Battery for sulfation recovers battery performance by the mode of " activation ", its principle is: decomposed gradually by inert matter (lead sulfate particle) under the effect of charge power supply, be converted into active material (sulfuric acid and lead), thus improve battery capacity.Traditional active mode is generally activated by the degree of depth " be full of → discharge (general release half capacity) → be full of " circulation, this mode is consistent with " property checked is discharged → charged " process in regular maintenance in essence, effect is very not obvious, and be deep discharge mode due to what adopt, frequent activation will have a strong impact on storage battery " circulation " useful life.Lead acid accumulator comprises " cycle life " and " float life " useful life.According to the difference of application scenario, emphasis is also different, and the production technology of employing also differs widely.As: electrokinetic cell stresses " cycle life ", and pole plate is thick; And the storage battery that power supply uses in support stresses " float life ", pole plate is thinner, therefore, will greatly shorten its useful life to the frequent degree of depth discharge and recharge of the backup battery stressing " float life ".
Utility model content
The purpose of this utility model is exactly to overcome above-mentioned problems of the prior art, and provides a kind of pulsed lead acid accumulator maintenance instrument, carries out activation process, recover battery performance to greatest extent to storage battery.Adopt unique " pulsed " active mode, the battery performance decline caused for sulfation has good repairing effect, effectively can eliminate " sulfation " phenomenon of storage battery.
The purpose of this utility model has been come by following technical solution.This pulsed lead acid accumulator maintenance instrument, comprise control module, discharge module, charging module and active module, storage battery is electrically connected with discharge module, charging module and active module by interface, control module is electrically connected with discharge module, charging module and active module respectively, wherein active module adopts the charge and discharge cycles of certain frequency, by PbSO
4particle breakdown, reduction, each " be full of → discharge → be full of " greatly in the cycle, comprise the pulse period T that many of N is little, and each pulse period comprises charging t
1with electric discharge t
2, in charging process, adopt the pulse mode of " fill → put "; In discharge process, too so.
The beneficial effects of the utility model are: the battery performance decline caused for sulfation has good repairing effect, both battery capacity was recovered to greatest extent, additionally reducing the impact on service lifetime of accumulator, is current optimal battery activation mode.Instrument has " charging ", " electric discharge ", " activation " three kinds of functions, and volume is little, lightweight, stable performance, reliable, can be widely used in storage battery regular maintenance.
Accompanying drawing explanation
Fig. 1 is systematic square frame schematic diagram of the present utility model.
Fig. 2 is activation principle schematic of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
Internal storage battery electrochemical reaction is:
Electric discharge: positive/negative plate active material (Pb, PbO
2) generate PbSO with sulfuric acid reaction
4;
Charging: under the effect of charging current, by PbSO
4be reduced to Pb, PbO
2and H
2sO
4.
So-called storage battery " sulfation ", mainly refers to the PbSO that internal storage battery generates
4particle cannot be reduced to active material (Pb, PbO completely
2, H
2sO
4), cause battery capacity to decline, internal resistance increases, as activated not in time, and PbSO
4particle can be increasing, makes storage battery accelerated deterioration.
As Figure 1-Figure 2, this pulsed lead acid accumulator maintenance instrument, comprise control module, discharge module, charging module and active module, storage battery is electrically connected with discharge module, charging module and active module by interface, control module is electrically connected with discharge module, charging module and active module respectively, wherein active module adopts the charge and discharge cycles of certain frequency, by PbSO
4particle breakdown, reduction, each " be full of → discharge → be full of " greatly in the cycle, comprise the pulse period T that many of N is little, and each pulse period comprises charging t
1with electric discharge t
2, in charging process, adopt the pulse mode of " fill → put "; In discharge process, too so.Through my company's long term test gained, this method declines to the battery capacity that " sulfation " causes and has obviously effect.
Adopt " pulsed " active mode, can well solve above-mentioned shortcomings, the battery performance decline caused for sulfation has good repairing effect, both battery capacity was recovered to greatest extent, additionally reducing the impact on service lifetime of accumulator, is current optimal battery activation mode.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
