1-24 Series High Precision Protection Board Tester BMS Tester
- Application and Function Introduction
1.1 Application: It is mainly used to detect whether the functional indexes of power battery
protection board are within the parameter range, so as to provide a set of detection standards for
staff. It is mainly used for the test of power battery protection board of protection board
manufacturers and power battery manufacturers.
1.2 Function Introduction: PBTS protection board test system is divided into fast test and
Accurate test: It can accurately detect the accurate value of various functional parameters of
the power battery protection board (the error is 5mv), facilitate the debugging and development
of samples, and provide a set of standards for rapid detection for R & D personnel.
Quick test: According to the design parameters of the protection board, set the test parameters
to conduct quick test, which is convenient for the protection board manufacturer and power
battery manufacturer to conduct large-scale and rapid test and delivery. It is also applicable to
the protection board test of various hardware schemes and some software schemes.
