I、Industry Background:

Wiring harness CCS (Cells Contact System) test is a test for electric connection structural parts used in power batteries of new energy vehicles. These structural parts are usually composed of FPC (flexible circuit board), plastic structural parts, copper and aluminum bars, etc., mainly divided into module sampling module FPC and module sampling module wiring harness two types. Due to the rapid development of new energy vehicles, FPC and CCS are more and more widely used in new energy vehicles, and the requirements for the reliability of their products are also getting higher and higher.

II、Application requirements:

1. Short break test.

2. temperature control resistance test.

3. welding resistance test.

4. AC and DC voltage test

5.DC insulation resistance test.

III、Solution:

CCS(Integrated bus) comprehensive test equipment developed by Ruijie Instrument is used for functional testing of wiring harness integrators of lithium battery modules and battery packs. After the test equipment manually plug the test harness in place, scan the barcode or two-dimensional code by the traceability system and software to confirm that the product information is OK, automatically call the corresponding test program, conduct automatic test, and automatically judge whether the test results are qualified, alarm the unqualified products, automatically record and save the test data locally, and upload the results to the MES traceability system.

The automatic test system adopts open hardware and software architecture, according to the function and performance test requirements of the tested product, comprehensively equipped with customized research and development of AC and DC voltage insulation tester, DC low resistance tester, multi-channel scanning unit, high voltage isolation unit and other test equipment; Industrial computer equipped with customized upper computer software, for users to achieve research and development of precision testing, production high-speed testing, quality sampling testing and other customized testing needs, to provide a complete set of reliable test solutions.
