Automatic testing system for battery equalization module packing

Abstract

An automatic testing system for battery equalization module packing comprises a PC (personal computer), an automatic test main control panel, at least one direct-current programmable power supply and a test table for holding equalization module packing panels, wherein multiple equalization modules are connected with the inside of the test table, the automatic test main control panel is electrically connected with the PC, the at least one direct-current programmable power supply and the test table for holding the equalization module packing panels respectively, the automatic test main control panel controls control connection lines used for connection with the test table to be connected and disconnected, whether each equalization module passes a test is judged by testing changes of voltage and currents of each control connection line, and accordingly whether performance of the equalization modules on the packing panels is qualified in different states is tested. The measurement accuracy and efficiency of the automatic testing system in voltage, current and other data are multiplied compared with a traditional manual testing mode, and the quality of ex-factory products can be improved.

Description

technical field [0001] The invention relates to the field of battery detection, in particular to a group automatic detection system of battery balancing modules. Background technique [0002] As the country attaches great importance to the control of environmental pollution, the development of clean energy electric vehicles has become a social trend. The biggest factor restricting the development of electric vehicles is the life of the lithium battery pack of the vehicle power supply, and there is a large gap between the single lithium batteries. Differences are generally packaged in series, and the charging and discharging process is carried out in the whole package, which leads to the fact that if the difference between the monomers is not dealt with, the life of the whole battery pack will be greatly shortened. Battery equalization technology is created to improve this problem. The battery equalization module is the basic unit of this technology. The whole battery pack n...

Problems solved by technology

[0003] Since the active equalization technology of power batteries has just started, the corresponding testing equipment is relatively scarce, especially there is no standard for the related testing technology and specific test content and test specifications of the equalization modules. The traditional module testing method is mainly through manual testing, and every Each module will involve some calculations, and it is inevitable that there will be mistakes, the test is not standardized, and the test items are not complete. It is very likely that there are unqualified products mixed in the tested products. Unknown consequences, serious ones will cause the single battery to be pulled off, thus affecting the life of the battery in the whole box

At the same time, traditional manual testing not only takes a lot of time and labor costs, but also makes it difficult to count the final test results of modules, which is also detrimental to product upgrades and development
