1. Product description
Battery charging and discharging test system is a computer controlled product developed by our company. Its software design uses computer big data processing away from the program master
A way of dynamically controlling bidirectional power supply. It not only realizes the requirement of automatic charge and discharge of bidirectional power supply, but also eliminates the workload of manual recording of test data, so as to realize the battery
Fully automatic charge and discharge.
Second, functional characteristics
The system has good flexibility for the expansion of power battery test, which is convenient for users to expand and adjust the system in the future.
It can meet the requirements of various standard dynamic test procedures to meet the needs of electric vehicle battery testing.
In a single test process, the test steps can be up to 255 steps, providing users with a wide range of features.
It provides data analysis curves of charge and discharge efficiency, capacity decay rate, current-voltage characteristics, etc., and can be easily converted into EXCEL documents for saving and printing.
The test program programming is flexible and convenient. Variable and programming can be used to realize a variety of combined test programs, and various conditions of vehicle operation can be simulated.
It has functions such as emergency cut-off switch, automatic shutdown after power failure, automatic load connection and disconnection.
