5V 3A 512 Channel Li Ion Battery Charging Discharging Tester For Cylinder Cell Capacity Testing

5V3A 512 Channel Li-ion Battery Charging Discharging Tester For Cylinder Cell Capacity Testing

Features:

1. Each device can carry out constant current and constant voltage charging and constant current discharge test on 512 batteries meeting the voltage range.

2. Adopt the constant current constant voltage power supply of the invention patent, constant current to constant voltage switching without impact, especially suitable for the charging requirements of lithium-ion battery.

3. The AVR single-chip computer is used as the control center of the equipment, and the peripheral sampling circuit is used. The equipment can be controlled by the superior computer. When the computer is connected, the complete charge discharge curve of all channels can be saved, or it can be separated from the superior computer. Through the operation of the control panel, the constant current and voltage charging, constant current discharge test, time sorting and other work can be completed.

Supporting Software Functions:

A) Graphic operation interface is used to display the data of voltage, current, time and capacity of each battery, and display the corresponding working status and abnormal conditions in various colors;

B) Battery capacity indication of any section (up to 100 sections);

C) Data points can be recorded according to the change conditions of voltage, current and time to form a complete charging and discharging curve data, and the time interval of curve data points is ≤ 4 Second; 

D) Carry out battery sorting function under various conditions (capacity, time, open circuit voltage, discharge platform, etc.);

E) Automatically calculate constant current charging ratio, capacity loss, discharge efficiency, average voltage, median voltage and other data;

F) Set operator authority and operate in different levels;
