Description

Storage battery pressure reduction method method for group matching
Technical field
The present invention relates to storage battery production field, be specifically related to storage battery pressure reduction method method for group matching.
Background technology
Valve-regulated lead-acid battery is cheap with it, safety, do not need to mend the features such as electrolyte, and electric road vehicle is widely applied.Battery generally needs series connection to use in groups, the overall performance of batteries depends on the joint that in whole Battery pack, performance is the poorest, if the performance of a whole set of batteries has big difference, cause the discreteness of this batteries, thus result in batteries premature failure, the life-span is short, therefore need to carry out combo detection to storage battery, the storage battery collocation making performance basically identical in groups, carries out bulk supply, to ensure performance and the life-span of whole batteries.Electric road vehicle battery is generally at more than 40Ah, and weight and volume is comparatively large, not easily carries, battery size and batch more, and quantity is had nothing in common with each other in groups, manyly at present carries out combo according to the method for group matching of capacity stepping, and comparatively greatly, and combo output capacity is not high for working strength.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of storage battery pressure reduction method method for group matching, reduces the carrying number of times in combo work, improves combo output capacity.
The present invention is achieved through the following technical solutions:
Storage battery pressure reduction method method for group matching, comprises the following steps:
(1) complete completely charged is treated that combo battery is numbered;
(2) 1/3 electric current of combo battery by its capacity corresponding current will be treated, the average final voltage of setting electric discharge is that 1.6 ~ 1.8V/ monomer carries out discharged in series, gather final voltage and the discharge time of every battery in process, the final voltage choosing equivalent discharge time is the battery participation combo of 1.60-1.90V/ monomer;
(3) battery participating in combo is fully charged, leaves standstill 12 ~ 48 hours after charging completely, gather the open circuit voltage of every battery respectively;
(4) by the numbering of participation combo battery, final voltage and open circuit voltage one_to_one corresponding, then first press final voltage sequence, open circuit voltage sequence is pressed on this sequence basis again;
(5) participation combo battery is carried out combo, mark group number mark by the combo standard of poor, the rear difference in open circuit voltage of first final voltage, rated voltage 2V/ cell combo standard only: stack battery quantity X≤30, final voltage difference≤0.06V, difference in open circuit voltage≤0.01V; Stack battery quantity 30 < X≤60, final voltage difference≤0.12V, difference in open circuit voltage≤0.012V; Stack battery quantity X > 60, final voltage difference≤0.2V, difference in open circuit voltage≤0.015V, rated voltage is the battery combo standard of cell multiple: quantity is divided by multiple in groups with cell for stack battery quantitative range, and corresponding final voltage difference and difference in open circuit voltage are multiplied by corresponding multiple by cell combo standard;
Take rated voltage as 12V/ battery of cell 6 multiple be example, its combo standard is:
Stack battery quantity X≤5, final voltage difference≤0.36V, difference in open circuit voltage≤0.06V; Stack battery quantity 5 < X≤10, final voltage difference≤0.72V, difference in open circuit voltage≤0.072V; Stack battery quantity X > 10, final voltage difference≤1.2V, difference in open circuit voltage≤0.09V;
(6) group number is marked identical battery to move to and pack together.
The further improvement project of the present invention is, the group number mark in step (1) in numbering and step (5) adopts marking pen to mark or form of labelling respectively.
The present invention compared with prior art, has following obvious advantage:
One, overall process of the present invention only needs to move primary cell, reduces workload, reduces labour intensity, saves cost of labor.
Two, the present invention is numbered every battery, carries out all-the-way tracking, and reduce mistake, combo success rate can reach 99%.
Embodiment
Below in conjunction with 12V150Ah battery combo example, the present invention is described further:
(1) by complete completely charged 999 rated voltages be 12V treat that combo battery is numbered A001-A999;
(2) will treat that combo battery uses 50A electric current, the average final voltage of setting electric discharge is that 10.8V/ only carries out discharged in series, gather in process every battery final voltage V1 and discharge time H, the final voltage choosing equivalent discharge time is that 9.6 ~ 11.4V/ battery only participates in combo;
(3) battery participating in combo is fully charged, leaves standstill 48 hours after charging completely, gather the open circuit voltage V2 of every battery respectively;
(4) by the numbering of participation combo battery, final voltage V1 and open circuit voltage V2 one_to_one corresponding, then first press final voltage V1 and sort, open circuit voltage V2 is pressed on this sequence basis again and sorts;
(5) combo, mark group number mark is carried out by participating in the combo standard of combo battery by poor, the rear open circuit voltage V2 difference of first final voltage V1, for 5 one group, according to rated voltage 12V/ battery combo standard only: stack battery quantity X≤5, final voltage V1 is poor≤and 0.36V, open circuit voltage V2 be poor≤0.06V;
Battery is numbered V1(V) V2(V) Group number
