Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0014] See figure 1 , figure 1 It is a flow chart of the cell assembly statistical method provided by the present invention.

[0015] The battery pack includes multiple battery modules, and each battery module includes multiple battery cells.

[0016] The battery assembly statistical method includes the following steps:

[0017] S1: Before assembling into a battery module, first test the performance of the battery cell 1, and divide the battery cell 1 into a qualified grade battery cell 11 and an unqualified grade battery cell 12 according to the test results.

[0018] S2: number each qualified grade battery cell 11, print the number of the battery cell on each qualified grade battery cell 11, and record the test results of the qualified grade battery cell 11 and the batter...

Abstract

The embodiment of the invention discloses a battery core assembly statistical method. The method comprises the following steps of: S1: prior to assembling of a battery module, detecting the performance of the battery core, and dividing the battery core into qualified level battery cores and unqualified level battery cores according to a detection result; S2: performing numbering of each qualifiedlevel battery core, and inputting the detection results of the qualified level battery cores and the numbers of the battery cores into a system; S3: assembling the qualified level battery cores into battery modules, numbering each battery module, detecting the battery modules, and inputting the detection results and the numbers of the battery modules into the system; and S4: assembling the batterymodules to battery packs, numbering each battery pack, detecting the battery packs, and inputting the detection results and the numbers of the battery packs into the system. The battery core assemblystatistical method employs hierarchical assembly, detection and coding to achieve comprehensive recording of the battery packs and the battery modules and the battery cores in the battery packs so asto facilitate follow-up and timely tracking and reduce the subsequent workload.

Description

technical field [0001] The invention relates to the technical field of battery assembly methods, in particular to a statistical method for battery assembly. Background technique [0002] With the rapid development of new energy vehicles, more and more environmental protection issues have gradually emerged, among which the most prominent is how to deal with the power battery in the car. The main method now adopted is to recycle the power battery. [0003] The battery pack contains multiple battery modules, and each battery module contains multiple battery cells. The existing situation is: after the recycled batteries are assembled into a battery pack, there is no accurate record of the performance of the battery cells in the entire battery pack, and the follow-up maintenance cannot be traced and maintained in time, which increases the follow-up maintenance workload. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned t...
