The invention provides a kind of lead acid accumulator combo method for separating, be intended to solve in prior art in batteries uniformity of storage batteries poor, the problem that useful life is short.
In order to solve above technical problem, by the consistency of controlling plate weight, the homogeneity of acid adding amount guarantees the consistency of battery capacity; By battery capacity consistency and the conforming screening of open circuit voltage, the result of battery combo sorting is more reliable again; Make battery there is longer useful life.The present invention is achieved through the following technical solutions:
A combo method for separating, comprises the following steps successively:
A. choose the accumulator plate of same model;
B. to meeting the accumulator plate of steps A, measure the weight of utmost point group, select the utmost point group of the homopolarity of quality error in-0.3%wt～0.3%wt;
C. to meeting the accumulator pole group in step B, by wrapper sheet, welding, tankage, sealing, complete semi-finished product assembling;
D. to meeting the semi-finished product storage battery in step C, in test storage battery add sour density, choose the semi-finished product storage battery of same acids density;
E. to meeting the storage battery of step D, measure single lattice acid adding amount in storage battery, choose single lattice acid adding amount in error the storage battery in-0.3%wt～0.3%wt;
F. to meeting the storage battery of step e, carry out battery charging and discharging and change into, select discharge capacity to be more than or equal to the storage battery of rated capacity;
G. to meeting the storage battery of step F, measure final discharging voltage, choose final discharging voltage in 10.00V～11.10V and the storage battery of the poor 0.03V of being less than or equal to of final discharging voltage;
H. to meeting the storage battery of step G, measure open circuit voltage, select open circuit voltage in 13.15V～13.65V and difference in open circuit voltage is less than or equal to the storage battery of 0.03V.
Further, in G step, the measurement of same group of interior final discharging voltage completed in two hours; Be conducive to reduce variation of ambient temperature and bring impact to measurement.
Further, in G step, before electric discharge, will before battery discharging, cooling water be bled off; The consistency of ambient temperature while guaranteeing battery discharging.
Further, in G step, be controlled at-0.01A～0.01A of current error during electric discharge; Be conducive to improve the transformation efficiency homogeneity of active material in storage battery.
Further, the battery capacity difference of choosing is in 0.5%; Increase the homogeneity of battery capacity, be conducive to improve the cycle life of storage battery.
