Product Description

5V**0A BATTERY PACK change and discharge 8 CHANNELS

One. The basic structure of the equipment
This equipment is mainly composed of a computer, a communication
interface and a battery detection cabinet. The battery detection cabinet is
composed of a fixture and a board for placing the fixture, a constant current
and constant voltage source, a register control circuit, a sampling circuit, a 
single-chip microcomputer and a control panel
 
Two. The main performance of the equipment
1. Each device can perform constant current and constant voltage charging
and constant current discharge tests on *4 batteries that meet the voltage
range.
2. It adopts the invention patented constant current-constant voltage power
supply, which has no impact when switching from constant current to
constant voltage, which is especially suitable for the charging requirements
of lithium-ion batteries.
3. The equipment adopts an AVR single-chip computer as the control center,
and cooperates with the peripheral sampling circuit, which can be controlled
by the upper-level computer. When connected to the computer, the
complete charge and discharge curves of all channels can be saved, or it 
can be separated from the upper-level computer and operated through the
control panel. Constant current and constant voltage charging, constant
current discharge test, sorting by time, etc.
4. Each battery completely has an independent constant current and
constant voltage source, which is self-contained and does not affect each
other.
5. Real-time detection of each battery voltage, when charging, first constant
current charging, when the battery voltage reaches the set value, it will
smoothly switch to constant voltage charging, when the set time or current
termination conditions are met, the charging ends. In constant current
discharge, when the battery voltage is lower than the set value, the
discharge ends and the corresponding battery indicator lights up.
6. With power failure protection function, it can continue to run after the
original work flow is connected.
7. The power tube adopts *0N*6, which is suitable for batteries that require
lower discharge voltage, such as lithium iron phosphate batteries.
8. The upper computer can set *2 step parameters and **6 cycles, and
each upper computer can be connected to ***0 sets of single-chip systems
(recommended less than *0 sets).
9. Supporting software functions.
 
a) Graphical operation interface is used to display the voltage, current, time,
capacity and other data of each battery, and the corresponding working
status and abnormal conditions are displayed in various colors;
b) Any segment battery capacity indication (up to **0 segments);
c) The data points can be recorded according to the changing conditions of
voltage, current, and time to form a complete charging and discharging
curve data. The time interval of the curve data points is less than 4 seconds
d) Various conditions (capacity, time, open circuit voltage, discharge
platform, etc.) for battery sorting function;
e) Automatic calculation of constant current charging ratio, capacity loss,
discharge efficiency, average voltage, median voltage and other data;
f) Operator authority setting, hierarchical operation;
g) It can display charge and discharge curve diagram and cycle diagram;
 
This machine have *4/*6 channels for optional.
