What process, and no matter arrange how many times charging and discharging in charge and discharge process, charge volume and discharge capacity added up to surplus fills
Charge volume compensation device 5, electricity sets to 0 that state is specified, and the span of this specified surplus charge volume is 1.5～
3.0C/Ah.Described surplus charge volume also referred to as repairs charge volume, and its definition is that charge volume deducts discharge capacity, remains and charges
The effect that magnitude relation is repaired to battery, surplus charge volume is too small can not to activate battery to be repaired, surplus charge volume mistake
Greatly and easily battery is filled bad, especially because long-term overcharge is led to that plate active material seriously softens the storage of inefficacy
Battery.Described charge volume compensation device 5 to set to 0 state related to its design form.
Charge volume compensation device 5 can have multiple design forms, in one embodiment, charge volume compensation device 5
It is designed as the selecting switch of n shelves, described n is >=1 positive integer, by user, the gear of selecting switch is selected,
Directly input the signal of adjustment control data to control module 1, make described control module 1 by the ratio of interior storage data
The control program of corresponding execution required for relatively accordingly selecting, thus control described charging module 3 to lead accumulator 6
Realize the compensation of charge volume；Outside this instrument in discharge and recharge manipulation charge volume compensate purpose of design can have multiple,
For example charge volume compensation device 5 is considered as a kind of adjusting apparatus of surplus charge volume, as the battery approximate to capacity
Automatically repair general or identical to capacity but need the battery of different surplus charge volumes to use as secondary discharge and recharge reparation；
Can also be identical to capacity but need the batteries of different surplus charge volumes at different ambient temperatures as temperature-compensating

From description before it is known that the charging process the discharge and recharge repair process that controlled of control module 1 belongs to sublevel
Section charges, the sublevel fall current charge in described charge the stage by stage constant current charge including charging early stage and later stage of charging,
And select the size checker of setting strength of charging current；For example, the current strength value of charging early stage
0.25C/A (selects to insert relatively low current of some minute 0.01～0.1C/A) therebetween, latter stage strength of charging current
Value 0.05C/A.In charging process, can also select to arrange the standing process that strength of charging current is 0.
In charging process, set discharge process is quantitative electric discharge, the electricity of specified releasing 0.01～0.5C/Ah,
Industry is used to claim shallow discharge, and the current strength span of this shallow discharge is generally 0.05～1.0C/A.This shallow discharge
The execution time of operation is relevant with the residual capacity in battery, and in general, residual capacity ＜ 0.7C worked as by battery
During/Ah, the repairing effect of phase setting shallow discharge is more preferable in charging；In the execution number of times and battery of shallow discharge operation
Residual capacity relevant, for the battery of residual capacity ＜ 0.5C/Ah, charging mid-term arranges multiple shallow discharge
Repairing effect can be more preferably.Described C/A is the current strength of lead accumulator 6 nominal capacity value.
Charge volume needed for battery is repaired is larger, charges than conventional battery and is more easy to generate heat, the little electricity of space changing
Current charge or standing certain time (such as 0.5～1h), the shallow discharge of particularly setting certain way (releases electric power storage
Pond part electric energy), to eliminate internal storage battery produce bubble, weaken both inner pad periphery electrolyte polarization concentration difference,
The efficiency improving next stage charging has more apparent effect.

Stage constant current, multistage constant current and non-steady current electric discharge.In the embodiment of a deep discharge, electric current is strong
Degree successively decreases rule setting for I=MKIe, wherein M represents degradation factor, IeCarry out the deep discharge incipient stage for battery
Rate of discharge, positive integer K represents the exponent number that successively decreases, the present embodiment preferably 0.618.Set when discharge voltage reaches
Definite value V2Afterwards, rate of discharge starts successively decreasing of the first rank, and K is 1, and rate of discharge drops to 0.618Ie,
Because electric current reduction is discharge load mitigating, cell voltage can nature rebound, when battery discharging voltage reaches again
V2, rate of discharge starts successively decreasing of second-order, and now K is changed into 2, and rate of discharge drops to 0.6182Ie
=0.382Ie... the like, until battery is with the small current intensity deep discharge that sets to V2, allow in the time
In the case of realize the above deep discharge of 3 ranks as far as possible, the logic flow that this realizes deep discharge to battery is as shown in Figure 3.
In general, last rank deep discharge is to V2When current strength preferably≤0.05C/A.

Average voltage calculates) corresponding impedance is as discharge load, deep to the average electric discharge of 0.2V/ single lattice to battery discharging
Degree.With a clear superiority of rated impedance deep discharge, it is that during deep discharge, current strength can putting with battery 6
Piezoelectric voltage declines and adjust automatically, and voltage its electric current lower is less, adjusts control circuit without impressed current, can letter
Singly be effectively realized the technical requirements to battery deep discharge, be particularly suited for single lattice battery, accompanying drawing 4 (a) and
Accompanying drawing 4 (b) is the voltage and current alteration trend schematic graph of deep discharge.
Battery repair process to be filled ability closely related with ambient temperature, than normal charge to external rings
Border temperature is more sensitive.Battery is filled ability preferably in 25 DEG C of temperature, when environment temperature is higher than 25 DEG C, electrification
The extent of reaction is aggravated, and need to suitably reduce charge volume；And when environment temperature is less than 25 DEG C, electro-chemical reaction degree dies down,
Charge volume need to suitably be increased.A kind of preferred coefficient of described charge volume temperature-compensating is as follows：When outside discharge and recharge instrument
When environment temperature is higher than 25 DEG C, averagely often rise the surplus charge volume of 1 DEG C of minimizing 0.02C/Ah；Outside discharge and recharge instrument
When environment temperature is less than 25 DEG C, averagely often decline the surplus charge volume of 1 DEG C of increase 0.03C/Ah.In actual design, no
Necessarily need charging module 3 to carry out meticulous Continuous Compensation to the surplus charge volume of battery 6, for example, can design every
3 DEG C or 5 DEG C of change is one grade, carries out stepping level compensation to the surplus charge volume of battery 6.
