Charging interval in each step, or total discharge capacity can obtain divided by corresponding current value according to total charge volume divided by corresponding current value.The rated capacity that wherein C is storage battery; Storage battery theoretical capacity equals anode diachylon amount of active mass divided by coefficient 4.463, and anode diachylon amount of active mass is determined when pole plate is manufactured.Rated capacity equals the achievement of theoretical capacity and active material utilization, and active material utilization is generally between 25%~45%.If active material utilization is 45%, the battery that is 100Ah for rated capacity, its theoretical capacity is 222Ah, if active material utilization is 25%, the battery that is 100Ah for rated capacity, its theoretical capacity is 400Ah.

Below in conjunction with matrix embodiment, technical scheme of the present invention is elaborated, but following embodiment is only the preferred embodiments of the present invention, not all.Embodiment based in execution mode, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection scope of the present invention.

A kind of preferred scheme in charge and discharge cycles formula storage battery internal formation process, step is as follows:

1) with 0.25C(A) current charges 640 minutes;

2) with 0.5C(A) current discharge 31 minutes;

3) with 0.25C(A) current charges 450 minutes;

4) with 0.5C(A) current discharge 37 minutes;

5) with 0.25C(A) current charges 450 minutes;

6) with 0.5C(A) current discharge 39 minutes;

7) with 0.25C(A) current charges 450 minutes;

8) with 0.5C(A) current discharge 41 minutes;

9) with 0.25C(A) current charges 512 minutes.

This scheme, by the experiment of many groups, is determined above-mentioned charging current and charging interval.In the time of charge in batteries, voltage can reach a limiting value, and the rising of voltage afterwards becomes slow.Record the flex point that voltage rises and changes, then by this flex point, determine the time of charging, therefore can improve the utilance of charge capacity, avoid the hot expense of electric energy.During electric discharge, consider whether discharge effect is conducive to depolarising.Because change into the polarization of later stage pole plate compare early stage more serious, need the electric discharge of deeper degree just can reach the effect of further generation lead sulfate, so increase gradually the discharge time in different step along with changing into degree.

Capacity check and the combo of after being internalized into end, carrying out storage battery, capacity check and combo comprise the following steps:

First, storage battery is with 0.5C(A) current discharge to the mono-lattice of 1.75V/, and measure storage battery and start to discharge into the time interval that is discharged to the mono-lattice of 1.75V/, coordinating of discharging current and the time interval can obtain the actual capacity of storage battery;

After detection, first use 0.17C(A) current charges 480 minutes; Battery fail full charge after large electric current quick charge, therefore uses 0.1C(A again) current charges 600 minutes.Not charging simply and waste too much electric weight of charging process, adjusts curent change, to improve the utilance of electric weight.

The effect of this internal formation process: the storage battery of 12V12Ah of take is example, changes into and need 96h before improvement, and charge volume is 167Ah; Adopting and changing into the time after internal formation process of the present invention is 65h, and charge volume is 153Ah.Change into time shorten, power consumption also reduces, and formation efficiency gets a promotion.

The operating process that staff is internalized into is specific as follows:

The first step is the preparatory stage; Operator should finish changing work clothes before entering scene, has dressed labour protection safety device.Used raw material, equipment, power supply, instrument are checked, guarantee that used raw material, equipment, the energy, instrument meet the requirements.

Second step is laying and the stage of arranging of storage battery; Storage battery acidification is complete, and self check is qualified with go-cart, is pulled to battery charger cradle afterwards.While taking storage battery, arrest on the other hand storage battery, hold bottom of storage battery on the other hand, be gently positioned over quietly on charging table top; During arrangement, 20 storage batterys of 12V series are a branch road, and 14 storage batterys of 16V series are a branch road, are greater than the arranged with interval of thumb between battery and battery.Operating personnel check whether accumulator polarity sign is correct afterwards, and the left side that guarantees terminals alignment function person is for just, and the right is for bearing; After placing, the positive terminal of the anodal corresponding line of storage battery, align, and the same direction of storage battery is placed side by side with terminals; Check that lug plate smears antiseptic oil and vaseline quality, smear the lug plate coating antiseptic oil of tackling storage battery when inhomogeneous.After detection, with crocodile clip, the storage battery in branch road is contacted.

For strengthening exhaust effect, in the conjuncted acid kettle acid adding hole of every storage battery, insert breather pipe, breather pipe must insert internal storage battery, is beneficial to that to discharge and recharge be the discharge of bubble.And check whether sour kettle and acid adding mouth place have acid to overflow, and whether breather pipe floats, there is must proofreading and correct of floating.

The 3rd step changes into the stage for checking and powering on, and measures respectively the voltage of each branch road before powering on universal instrument, if magnitude of voltage, lower than 250V, carries out by only measuring storage battery in this branch road, finds out the storage battery of electric voltage exception and by its replacing.The positive and negative electrode that checks storage battery arrange and wiring whether correct, confirm that charger is in standby or stopped status, the positive and negative electrode of every branched battery is connected with the positive and negative electrode of charger respectively after errorless.By internal formation process, the program of discharging and recharging is set on computers.Be internalized in process and control battery temp lower than 55 ℃, to guarantee to change into the quality of rear storage battery, and can avoid occurring security incident.

The 4th step is capacity check and combo stage, according to the operation card of capacity check and combo, has required.

By above-described embodiment, object of the present invention is by fully effective having reached.The personage who is familiar with this technology should be understood that and the present invention includes but not limit the content of describing in embodiment above.Anyly do not depart from modification of the present invention and all will be included in the scope of claims.
