Description
Technical field
The present invention relates to a kind of lithium-ion battery classification method based on charging modes, belong to the battery detecting field.
Background technology
the lithium ion battery of existing market changes into screening installation, majority changes into sorting for discharging and recharging two kinds of devices to battery, normally first battery charging and discharging is carried out sorting to battery again, do not need discharge but battery has in formation process, but because battery performance is different, again of a sort battery is picked out, therefore add discharge process to carry out sorting to battery, the time loss that changes into of battery is in discharge like this, this shows and lack a kind of equipment that just can out can save time battery sorting and can save cost on market in the charging formation process.
Summary of the invention
The present invention is intended to invent a kind of lithium-ion battery classification method based on charging modes, according to the data of the charging process of battery, battery is carried out sorting, do not need again to reduce the time of sorting work through overdischarge, improved the efficient of work, and can saves energy consumption.
For realizing above-mentioned purpose, the present invention adopts following scheme:
As shown in Figure 1, a kind of lithium-ion battery classification method based on charging modes comprises host computer A, master control unit Z, charging system C, battery B, sampling apparatus D; See accompanying drawing 1.
Below in conjunction with accompanying drawing 1, the course of work of the present invention is described:
Host computer A sends order and turns constant voltage charge to master control unit Z for constant current charge, master control unit Z controls charging system C and charges to battery B, sampling system D detects battery simultaneously, the state that detects is passed to master control unit Z, and voltage, electric current, time, capacity that master control unit Z calculates battery are passed to host computer A and are stored and show.
Data or curve according to battery charging process, can obtain battery in the total capacity of constant current charge stage capacity, constant voltage charge stage capacity and battery charging, account for the percentage of total capacity and two conditions of total capacity of battery charging are selected parameter as battery according to the capacity in constant current charge stage, the battery that will meet is classified as a class, thereby realizes battery sorting.
Beneficial effect of the present invention:
(1) owing to not needing battery discharge, compare with other mode classifications, reduced the time of sorting work, and reduced the energy consumption of assorting room.
(2) separating effect is than simple better according to the mode classification of discharge capacity, because two parameters of capacity of having used charging total capacity and discharge regime are carried out sorting, can sort out by the battery that the constant-current phase state consistency of battery is consistent with total capacity, more excellent theoretically than single total capacity mode classification, and also better from facts have proved.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention.
Embodiment:
In order to make technical scheme of the present invention clearer, below in conjunction with drawings and Examples, invention is further described, instantiation described herein only in order to explain the present invention, is not limited to the present invention.
Practical measuring examples 1:
(1) get 200 18650 type lithium ion batteries, be divided into 2 groups, 100 every group;
(2) first groups are used method for separating of the present invention to carry out sorting, and sorting table work 1.5 hours is selected 8 similar batteries after finishing and is composed in series a battery pack from 100 batteries;
(3) second groups are adopted the discharge capacity classification to carry out sorting, and sorting table work 2.8 hours is selected 8 similar batteries after finishing and is composed in series a battery pack from 100 batteries;
(4) respectively two Battery packs are successively placed on an electric tool, charging after work is electric to nothing, 50 weeks of iterative cycles, from battery pack, cell is taken out, test on accurate laboratory equipment;
(5) result shows the test capacity maximum deviation of 8 batteries of first group in 2mA, and the test capacity maximum deviation of 8 batteries of second group proves that method for separating of the present invention is feasible and is better than simple capacity separating method in 20mA.
