Product 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.
4. Each battery has an independent constant current and voltage
source, and the self-made circuit does not affect each other.
5. Detect the voltage of each battery in real time. When charging,
charge at constant current first. 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 will end. During constant current discharge, when
the battery voltage is lower than the set value, the discharge is
ended and the corresponding battery indicator light is on.
6. It has the function of power-off protection, and can continue to
operate after receiving the original workflow.
7. The power tube is 50N06, which is suitable for batteries
requiring low discharge voltage, such as lithium iron phosphate
battery.
8. The upper computer can set 32 working step parameters and 256
cycles, and each upper computer can be connected with 1-10 sets of
single-chip system (less than 10 sets are recommended).
