5V 40A 128 Channels Polymer Pouch Lithium Cell Testing Machine

5V 40A 128 Channels Polymer Pouch Lithium Cell Testing Machine

Product Description

ACEY-PCT540-128 pouch lithium cell testing machine is designed for formation and capacity grading of pouch (polymer) lithium cells. Each channel provides a maximum output of 5V 40A, with 128 fully independent channels for simultaneous multi-cell testing. It offers stable constant current and constant voltage control, precise data acquisition, and reliable capacity classification. The system is suitable for batch production, performance evaluation, and quality control in pouch cell manufacturing.

Equipment Workflow
The equipment 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 board, controlled by the CPU, maintains constant current and voltage. When charging the battery, a bidirectional power supply converts AC power to 14V DC, which is then used by the constant current board to control and monitor the battery charge. When discharging, the process is the reverse of charging: the constant current board first raises the battery voltage to 15V, and then the bidirectional power supply converts the DC power to AC, which is then fed directly into the factory's AC distribution network, thus regenerating the discharged battery energy.

Features

1. Single-point independent, each battery has a completely independent constant current and constant voltage source, stable and shock-free. It adopts 8-channel program-controlled constant current and constant voltage control module.
2. The lithium ion cell tester adopts APM32 microcontroller control, connected by the computer work, can save all the test data and curves, can also be operated directly through the equipment keyboard board, set the process to complete the test and sorting.
3. Real-time detection and display of the status of each battery, if abnormal, will stop the channel work and the indicator light is on.
4. Has a power-down protection function, after the incoming call can be connected to the original workflow to continue to run. 
5. Power tube using field effect tube, suitable for lower voltage discharge batteries, such as lithium iron phosphate batteries. 
6. Adopts graphical operation interface, intuitive and clear, at the same time display the battery voltage, current, time, capacity and other data and can be set in different colors to display the corresponding work status and abnormal conditions.
7. 0.05% precision, data recording time 1 second/time, high stability. 
8. Powerful software and friendly man-machine interface.
9. 4-wire test interface ensures high measurement accuracy. 
10. Modular design concept, easy to maintain.
