5V60A 32-Channel Formation and Grading Cabinet Tester For Prismatic Cell Voltage and Capacity Testing

 

1. Equipment Overview

1.1 Equipment Structure and Working Principle

1.1.1 Equipment Overview

This equipment is primarily designed for testing parameters such as voltage and capacity during the formation and grading phases of battery production. Based on the test results, the batteries are categorized, and the data is analyzed, uploaded, and shared.

1.1.2 Equipment Features

1. Independent Channels: Each battery has an independent constant current and constant voltage source, ensuring stable operation without surges. The system uses a 4-channel programmable constant current and voltage control module.

2. STM32 Microcontroller Control: The equipment is controlled by an STM32 microcontroller, connected to a computer for data storage and curve display. It can also be operated via the device’s control panel, allowing the user to set processes, complete tests, and perform sorting.

3. Real-time Monitoring: The system detects and displays the status of each battery in real-time. If an anomaly is detected, the affected channel will stop, and an indicator light will turn on.

4. Power Failure Protection: The system has power failure protection, allowing it to resume the previous workflow once power is restored.

5. MOSFET Power Transistors: Suitable for lower voltage discharge batteries like lithium iron phosphate batteries.

6. Graphical Interface: The user interface displays battery voltage, current, time, and capacity data, with the ability to set different colors to indicate operating status and anomalies.

7. High Accuracy: The equipment has an accuracy of 0.05%, with data recorded every second, ensuring high stability.

8. Powerful Software: The software is robust and user-friendly.

9. Four-wire Testing Interface: Ensures high measurement accuracy.

10. Modular Design: Easy maintenance.

Note: Users are advised to equip each computer with a UPS (Uninterruptible Power Supply) to prevent damage to the computer or data loss in case of a power outage. A single computer can connect up to 10 devices to avoid affecting performance.

1.1.4 Equipment Workflow Diagram

The equipment operates as follows:

1. Computer Control: The equipment is connected to a computer, which sends commands and collects data. The computer also monitors and controls the entire process.

2. Manual Operation: The device can also be manually operated using a keypad that displays various parameters and statuses.

3. Constant Current Board: The constant current board, controlled by the CPU, is responsible for maintaining constant current and voltage levels during operation.

4. Charging Process: When charging the battery, the bidirectional power supply converts AC (alternating current) into 14V DC (direct current). The constant current board then controls and monitors the charging process.

5. Discharging Process: During discharging, the process is reversed. The constant current board first raises the battery voltage to 15V, and the bidirectional power supply then converts this DC back into AC, which is fed directly into the factory's AC distribution network, thereby allowing the energy from the battery discharge to be recovered and reused.
