Prismatic Cell Automatic Sorting Machine with High-Precision IR & Voltage Testing (10-Grade Classification)

Product Overview

The TOB-FX11 prismatic cell automatic sorting machine is a fully automated system designed for barcode scanning, internal resistance (IR) and voltage testing, and multi-grade sorting of aluminum shell lithium-ion cells. It integrates testing and classification into a single workflow, enabling consistent cell grouping based on defined electrical parameters.

This automatic sorting machine is widely used in lithium-ion battery production where inconsistent cell matching leads to pack imbalance, reduced cycle life, and safety risks. By delivering high-precision IR and voltage measurement with automated grading, it ensures stable grouping before module assembly.

Developed based on TOB NEW ENERGY’s 24 years of battery engineering experience, the system has been validated across in-house pilot lines and real production environments. It supports efficient cell screening with traceable data and stable throughput, reducing manual error and improving pack consistency.

Specification Interpretation & Application

The ±0.00001V voltage accuracy and ±0.01 mΩ internal resistance resolution are critical for precise cell grouping, especially in high-energy-density lithium-ion systems where small deviations can significantly affect pack balance and thermal behavior. The 10-channel sorting structure allows flexible grading strategies for different cell matching requirements in module and pack assembly.

With ≥550 cells/hour throughput, this system supports pilot-scale production and incoming quality control. The integration of barcode scanning and data logging enables traceability, which is essential for process validation and quality audits.

This automatic sorting machine is typically positioned after formation and aging processes, and integrates with upstream systems such as Battery Formation and Aging System and downstream assembly processes within a complete Battery Production Line.
