5V 10A 256 Channel Lithium Cylindrical Cell Grading Machine With Horizontal Tray And Energy Regenative Function

Ⅰ.Main Function

● Modular manufacturing is adopted, with strong universality and easy maintenance.

● Four wire method is adopted to improve the measurement accuracy.

● Each battery channel has a completely independent constant current and voltage source, which forms a loop and does not affect each other.

● The equipment adopts the control mode of whole machine process transmission.

● The sampling speed is fast, and the inspection time of the whole cabinet is ≤8s.

● Complete windows platform software with powerful functions, friendly man-machine interface and simple operation. The upper computer can set up to 64 work steps and 256 cycles. 

Each formation step can be selected by four attributes: constant current charging, constant voltage charging, constant current discharge and sleep.

● Be able to draw the dynamic curve of each battery in real time,  including voltage / time curve, current / time curve, capacity / time curve, energy / time curve, capacity / voltage curve and other functional menus.

● LED indicator is used to indicate the working state of the battery.

● Communication mode: TCP / IP.

● Each upper computer can monitor up to 22 devices.

● It has the function of data power failure protection, and can continue to operate when there is an incoming call.

● The lower computer can work offline for a long time.

● The software has the functions of file editing and modification of chemical composition and volume separation process library, new    monitoring, opening and closing documents, printing and setting.
