Negative Pressure Formation Machine for Prismatic Cell
Model: MR-FYHC-5V20A
Negative Pressure Formation Machine for Prismatic Cell is primarily designed for testing parameters such as voltage, capacity, and other factors during the formation and capacity sorting stages of battery production. Based on the test results, it performs battery classification, data analysis, and uploads for sharing and further use.
Features
1. Independent Single-Point Testing: Each battery testing channel can be independently set for charge and discharge steps.
2. STM32 Microcontroller Control: The equipment is controlled by an STM32 microcontroller and connects to a computer for operation. It can save all test data and curves and can also be operated directly through the device's keypad. The process is set up to complete tests and sorting.
3. Real-Time Monitoring and Display: The status of each battery is monitored and displayed in real-time. If an anomaly is detected, the channel will stop working, and the indicator light will illuminate.
4. Power-Off Protection: The equipment has a power-off protection function, allowing it to resume the original working process after power is restored.
5. ower Transistors: The power transistors use field-effect transistors (FETs), making them suitable for discharging batteries with lower voltages, such as lithium iron phosphate batteries.
6. Graphical User Interface: The equipment uses a graphical user interface for intuitive operation, displaying battery voltage, current, time, capacity, etc., with different colors to indicate the operational status and any anomalies.
7. Powerful Software and User-Friendly Interface: The software is robust, with a user-friendly interface.
8. Four-Wire Test Interface: The four-wire test interface ensures high measurement accuracy.
9. Modular Design: The modular design concept makes maintenance easier.
10. Energy Efficiency: Real-world tests show that this equipment reduces power consumption during charging by over 40% compared to traditional equipment, with an overall energy saving rate of over 60%, significantly cutting costs for battery manufacturers.
Note: It is recommended that each computer be equipped with an UPS power supply to prevent damage to the computer or data during power outages. A maximum of 10 devices should be connected to one computer to avoid affecting the computer's performance.

Negative Pressure Formation Machine Workflow Diagram
The equipment is controlled by a computer, which sends commands and collects data. The keyboard can be used to manually operate the device, display parameters, and status. The constant current board is controlled by the CPU, ensuring both constant current and constant voltage functions. During battery charging, the bidirectional power supply converts AC to 12V DC, and the constant current board regulates and monitors the charging process. When the battery discharges, the process reverses: the constant current board first increases the battery voltage to 12V, and then the bidirectional power supply converts DC to AC, which is fed back into the factory's AC distribution grid, achieving energy recovery during battery discharge.
