Device main function
Modular manufacturing, strong versatility, easy maintenance
The four - line method is adopted to improve the test accuracy
Each channel has a completely independent constant current and constant voltage source, which has no influence on each other
The device adopts the control mode of whole machine flow sending
The sampling speed is fast, and the inspection time of the whole cabinet is less than 6S
Complete WINDOWS platform software, software powerful, friendly man-machine interface, simple operation. The upper computer can set up to 32 working steps and 256 cycles, and each step can be selected by four attributes, such as constant current charging, constant voltage charging, constant current discharging, and sleep
It can draw the dynamic curve of each battery formation and grading process in real time, including voltage/time curve, current/time curve, capacity/time curve, energy/time curve, capacity/voltage curve and other functional menus
Use LED indicator to indicate the working status of the battery
Communication mode: RS485/WIFI
Each upper computer can monitor a maximum of 10 devices
With data power off protection function, can continue to run after power on
The software has the functions of editing and modifying process library files, creating monitoring, opening and closing documents, printing and setting
