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;
Display charge discharge curve and cycle chart;
