5V 1A 512-Channel Lithium Ion Cell Tester Pouch Battery Formation And Grading System

5V 1A 512-Channel Lithium Ion Cell Tester Pouch Battery Formation And Grading System

Description

The device is connected to a computer for control, sending commands and collecting data. A keyboard allows for manual operation and displays parameters and status. The constant current plate, controlled by the CPU, maintains constant current and voltage. During battery charging and discharging, the constant current plate controls and monitors the battery's charge and discharge. The charging process utilizes a seamless CCCV transition, eliminating any voltage or current surges. This effectively prevents heat concentration from peak currents, which can lead to tab powder loss or micro-shorting, resulting in islanding or overcharge.

System Features

• Each battery channel is equipped with an independent constant-current and constant-voltage source, ensuring stable operation without impact.
• The equipment is controlled by an AVR microcontroller and connected to a computer for operation. All test data and curves can be saved, or tests can be performed directly through the device’s keyboard panel by setting up the process and executing sorting.
• The system continuously monitors and displays the status of each battery. If an abnormal condition occurs, the corresponding channel will stop automatically and the indicator light will turn on.
• It features power-off protection; the system can resume the previous test process automatically when power is restored.
• Power components use MOSFETs, suitable for batteries with lower discharge voltage, such as LiFePO₄ batteries.
• The system adopts a graphical user interface for intuitive operation, displaying each battery’s voltage, current, time, and capacity in real time, with color-coded indicators for different operating states and abnormal conditions.
• It is recommended to equip each computer with a UPS power supply to prevent data loss or computer damage during power outages. Each computer can connect up to 10 devices to ensure stable performance.
