It is mainly used to detect whether the 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. It is mainly used for testing the power battery protection board of the protection board manufacturer and the power battery manufacturer. It is suitable for the protection board test of various hardware schemes and some software schemes.
Fast Test, Precise Test and Laboratory Mode, etc.
Precise Test:It can accurately detect the accurate values of various functional parameters of the power battery protection board (the error is 1mV), which is convenient for the debugging and development of samples, and provides a set of standards for rapid detection for the R&D personnel.
Quick Test:According to the design parameters of the protection board, the test parameters are set to carry out the rapid test, which is convenient for the protection board manufacturers and power battery manufacturers to carry out large-scale rapid test and shipment. At the same time, it is suitable for the protection board test of various hardware schemes and some software schemes.
Laboratory Mode: Set single string voltage independently, select charging or discharging mode separately, judge MOS tube closing or conduction.
Routine Test Items:Internal resistance test, overcharge and overdischarge test, overcharge recovery and overdischarge recovery test, overcurrent test (charging and discharging overcurrent), overcharge protection voltage, overcharge recovery voltage, overdischarge protection voltage, overdischarge recovery voltage and overcurrent protection.
Special Test Items:Short circuit protection test (refers to the real short circuit protection test microsecond level); Single section self consumption test (refers to the true and accurate self consumption of each section); Equalizing current and equalizing voltage (it can accurately grasp the equalizing current and equalizing opening voltage).
Types of Protection Boards Supporting Testing:LiFePO4 ,LiCoO3,LiMn2O4,Li4Ti5O12,etc.(reference voltage adjustable)
High Current Module: The current level is 150A and the current accuracy is 0.1A.
