Background technique
After electric power storage tank discharge, last point of active material of pole plate will become lead sulfate, these lead sulfates should be tiny
Crystalline solid can be gradually reduced during the charging process.It is placed for a long time after overdischarge and electric discharge in the case where do not charge, sulfuric acid
Lead crystalline solid can become thick and hard, and electrolyte can be hindered to be chemically reacted with the active material on pole plate, reduce activity
The actuating quantity of substance simultaneously makes pole plate resistance become larger.When occurring coarse and hard lead sulfate crystalline solid on pole plate, referred to as pole plate
Sulphation or plate vulcanizing.When there is plate vulcanizing situation, the capacity of battery is reduced, resistance becomes larger, this is to cause to store
Shorter battery life, the main reason for scrapping in advance.

Active material out, for this method the disadvantage is that too cumbersome, cost is too high, increases the internal resistance of cell, and also changes the former knot of electrolyte
Structure.Pulse repairing method comes to carry out shock oscillation to the sulfuric acid leading crystal of sulfation with the pulse of certain frequency, inhibits sulfuric acid
Leading crystal continued growth simultaneously eliminates sulfation, so that the lead sulfate for vulcanizing internal storage battery participates in electricity in charge and discharge process
Chemical reaction is converted into reversible lead sulfate by original irreversible lead sulfate, but is the need for dedicated pulse charger, general
Logical pulse charger does not have devulcanization effect.Although the above method is all a degree of to realize devulcanization, all do not have
Have in view of plate vulcanizing rank is different, it should use different devulcanization methods, and use same devulcanization method, cause

A kind of battery classification devulcanization method for applying example offer includes following steps.
Step 101: obtaining state of cure (vulcanization) hierarchical table；The state of cure (vulcanization) hierarchical table includes accumulator voltage, battery
Internal resistance multiple, vulcanization rank and the accumulator voltage, the accumulator internal resistance multiple, the correspondence for vulcanizing rank
Relationship；The vulcanization rank includes four ranks, and respectively slight vulcanization, seriously vulcanizes and abandons repairing general vulcanization.
Step 102: obtaining vulcanization rank table corresponding with vulcanization；It include four in the vulcanization rank table corresponding with vulcanization
Kind corresponding relationship, respectively when the vulcanization rank is the slight vulcanization, corresponding vulcanization is to overcharge electrical method；The mistake
Mise-a-la-masse method is the standard charging rate electric current with half to battery trickle charge, until battery voltage continues after reaching maximum value
It charges half an hour, is then allowed to stand two hours, when the end voltage of battery and internal resistance stop after interior no longer variation when two is small；Work as institute
Stating corresponding vulcanization when vulcanization rank is the general vulcanization is low current charge method；The low current charge method is to use
0.05C10H rate electric current charges to battery, and the voltage for being charged to battery cell stops charging half an hour after 2.5V or more,
Make electrolyte diffusion uniformly, then uses 0.02C1OH rate electric current continues after charging two hours to battery, then stops charging half small
When, repeatedly after, stand two hours, when the end voltage of battery and internal resistance when two is small it is interior no longer change after stop；Work as institute
Stating corresponding vulcanization when vulcanization rank is the serious vulcanization is hydrotherapy；The hydrotherapy is battery after fully charged,

Determine the vulcanization of the battery to be processed, and using the vulcanization of the battery to be processed to the battery to be processed
Carry out devulcanization operation.
Step 101 specifically includes:
After electric power storage tank discharge, the main performance of plate sulfation is: (1) since the actuating quantity of plate active material reduce,
The capacity of battery reduces, and state of cure (vulcanization) is more serious, and capacity is lower, and capacity is obviously insufficient when use, and voltage declines very
Fastly.(2) since sulfuric acid leading crystal cannot be restored sufficiently, reduce density of electrolyte.(3) resistance becomes larger, when battery charges, electricity
It is very high to solve liquid temperature rise, quickly rises to 40 DEG C.(4) it starts to charge and charging terminates, accumulator voltage is excessively high.
Since state of cure (vulcanization) and accumulator capacity are inversely proportional, state of cure (vulcanization) is more serious, and the capacity of battery is lower.Meanwhile
State of cure (vulcanization) is also related to accumulator internal resistance, and state of cure (vulcanization) is more serious, and accumulator internal resistance is bigger.Therefore pass through measurement battery
End voltage estimates the capacity of battery with internal resistance, and the different stage of state of cure (vulcanization) is determined according to capacity and internal resistance.This hair
State of cure (vulcanization) is divided into four ranks in bright embodiment, respectively slight vulcanization, seriously vulcanizes and abandons repairing general vulcanization
It is multiple.
Below by taking 12V battery as an example, the accumulator voltage provided according to Ai Moke Utilities Electric Co., Ltd. of the U.S. (is opened a way
State) with the relationship of residual capacity, obtain table 1.After fully charged, after standing half an hour, its end voltage is measured in 12.8V < U
When < 13.4V, it is such as more than that explanation is electrolyte that residual capacity, which is 100% or so of nominal capacity, but may not exceed 13.4V
Excessive concentration, it may occur however that dehydration.When holding voltage to drop to 12.4V or so, residual capacity only has original 80% or so, when
When end voltage drops to 12.2V or so, residual capacity only has original 60% or so, when holding voltage to drop to 12V or so, remains
Covolume amount only has original 40% or so.When drop to 11.5V and it is following when, substantially may determine that battery has damaged, and abandons
It repairs.
The relationship of table 1 battery terminal voltage and residual capacity
| It holds voltage (V) | 12.8<U<13.4 | 12.4 | 12.2 | 12 | 11.5 |
| Residual capacity (%) | 100 | 80 | 60 | 40 | 0 |
The residual capacity relationship of accumulator internal resistance and battery such as table 2, state of cure (vulcanization) is corresponding with voltage, internal resistance multiple is held to close
System such as table 3.When the internal resistance value of battery is more than 1.25 times of its nominal value, residual capacity drops to the 80% of its nominal capacity
Left and right.When the internal resistance value of battery is more than 1.5 times of its nominal value, residual capacity drop to the 80% of its nominal capacity with
Under, but not it is lower than 60%.When the internal resistance value of battery is more than 2 times of nominal value, abandon repairing at this time.
The relationship of table 2 internal resistance of cell and residual capacity
| Internal resistance multiple | 1.0~1.25 | 1.25~1.5 | 1.5~2 | >2 |
| Residual capacity (%) | >80 | 80~60 | 60~40 | 40 or less |
3 state of cure (vulcanization) hierarchical table of table
