Semco SI BMST 1-16S (40A 120A)/ 1-24S (40A 120A)/1-32S (40A 150A) WITH CABINET

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

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 a 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.

Main Performance Of Test Equipment:

• Routine test items: Internal resistance test, overcharge and over-discharge test, overcharge recovery and over-discharge recovery test, over Current test (charge over current and discharge over current) overcharge protection voltage, overcharge recovery voltage, over-discharge protection voltage, over discharge recovery voltage, over current protection,
• Unique test items: Short-circuit protection test (refers to the real short-circuit protection test in microseconds). Single-cell self-consumption test (refers to the true and accurate self-consumption of each cell). Equalization current and equalization voltage (can accurately capture equalization current and equalization opening voltage). Infrared scanning (bar code scanning) scans the ID number of each protection board and stores the
• Types of protection boards that support testing: Lithium iron phosphate, ternary lithium Cobalt oxide, and lithium.

Technical Parameter:

• High current module: the current level is 120A, current accuracy is 1A.
