Product Details

Semi-Automatic 1-24 Series Power Lithium Battery Detection Internal Resistance Protection Board Comprehensive Tester


BMS Tester Description

 

The multi-functional protection BMS board testing system is mainly used to detect whether the various functional indicators of the power battery protection board are within the parameter range, so as to provide a set of testing standards for the staff, and is mainly used for the protection board manufacturers and power battery manufacturers. Battery protection board test. Suitable for various hardware solutions and some software solutions protection board testing

 

BMS Tester Features

 

1. Short circuit protection test (refers to the real short circuit protection test microsecond level)
2. Single-section self-consumption test (refers to the true and accurate self-consumption of each section)
3. Balanced current and balanced voltage (can accurately capture balanced current and balanced opening voltage)


Why is it worth to have a protective board test instrument?


The protection board is soldered on the battery core to protect the battery core.
When the battery voltage is too high or too high during use.
Low, when the current is too large, and the voltage is inconsistent, the protection board will play its role to power off the entire battery. 
Test fixtures that can often see the performance of various test protection boards, test fixtures can be roughly divided into two categories
Charge and discharge test (connected to the battery pack can charge and discharge OK, advantage: test efficiency is very high, basically one second can test one BMS.
Finished Disadvantages: Protection board charging and discharging protection performance is equivalent to no test) The second type of fixture is the basic performance test of the protection board (Advantages: It can be tested whether the voltage of the protection board and the over-current of the protection board are protected. Disadvantages: the test module is multi-effect
The rate is low, the single-section self-consumption can not be tested, and manual switching is prone to missed detection). It can be based on customers
The project of the household demand test is freely matched, and the accurate test can accurately test the performance parameters of the protection board.
The quick mode can quickly determine if the protection board parameters are within the setting range.
