I. Equipment functional characteristics:

*The equipment includes brand computer, software system, precision voltage internal resistance measuring instrument, code scanning mechanism, batch loading device, automatic grading of manipulator, automatic blanking and other devices.

*According to the AC internal resistance, open circuit voltage and other parameters of lithium batteries, the batteries are accurately graded and grouped according to various performance parameters. The maximum number of graded pairs at one time is 8, which improves the consistency of pack battery quality and paired cell performance.

*AC internal resistance and open circuit voltage can be collected automatically by using the built-in high-precision internal resistance meter BT3562A. The sorting process is automatically controlled. It is simple to operate, and manual participation is abandoned. This ensures the accuracy of test parameters and the reliability of the pairing process, and improves and guarantees the performance and quality of pack products.

*High degree of automation, simple operation, hopper feeding, simple operation, about 600 electric cores can be tested and assembled per hour, which can effectively improve production efficiency and reduce production costs.

*The performance data of the electric core tested by the system shall be managed by the database, which shall be kept for a long time with strong traceability. Cooperate with the data analysis function of the software to conduct long-term monitoring and analysis on product performance and quality to guide the improvement of R&D formula and production process.

*The industrial control computer collects the data and automatically generates the curve chart and bar chart. The system has the database function, which can trace the historical data and export it.
