I. Equipment Overview:

1. The equipment includes a brand computer, software system, precision voltage and internal resistance measuring instrument, code scanning and batch feeding devices, automatic grading of trolley modules, automatic blanking devices, etc.

2. Based on the parameters such as AC internal resistance and open-circuit voltage of lithium batteries, the batteries are accurately graded and grouped according to various performance parameters. The maximum number of groups that can be graded and paired at one time is 5, which improves the quality of pack batteries and the consistency of the performance of paired cells.

3. The collection of AC internal resistance and open-circuit voltage can be automatically collected by the high-precision internal resistance meter HIOKI BT3562A equipped with this equipment. The sorting process is automatically controlled, with simple operation and no manual participation, ensuring the accuracy of test parameters and the reliability of the pairing process, thus improving and guaranteeing the performance and quality of products.

4. It features a high degree of automation and simple operation. With hopper feeding and easy operation, it can test and group about 600 cells per hour, which can effectively improve production efficiency and reduce production costs.

5. The cell performance data tested by the system is managed in a database mode, which is stored for a long time with strong traceability. Combined with the data analysis function of the software, it can conduct long-term monitoring and analysis of product performance and quality to guide the improvement of R&D formulas and production processes.

6. Data is collected by the industrial control computer, and graphs and bar charts are automatically generated. The system has a database function, which can trace historical data and export it.
