Semco SI BMST 1-16S With Cabinet

  1. Introduction to the scope and function of the equipment 

Scope of application: mainly used to detect whether the functional indicators of the power battery protection board are in the parameter range In order to provide staff with a set of testing standards. It is mainly used to test the power battery protection board of the protection board manufacturer and the power battery manufacturer.

Function introduction: PBTS protection board test system, divided into two types: Quick test and precise test.

Accurate testing: It can accurately detect the precise value of each functional parameter of the power battery protection board (the error is 5mv), which is convenient for the debugging and development of samples, and provides a set of standards for rapid testing to R&D personnel. Quick test: According to the design parameters of the protection board, set the test parameters for quick test, which is convenient for the protection board manufacturers and power battery manufacturers to quickly test and ship on a large scale. At the same time, it is suitable for various hardware schemes and part of the software scheme protection board test.
