Measures open-circuit voltage and internal resistance after formation to screen electrical consistency of finished cells.
Why this machine: This system serves as the critical final gate for both quality and functional safety, transforming raw data into strategic assets. It does more than just sort cells; it guarantees that only electrically consistent units proceed to module assembly, directly preventing premature pack failure. Moreover, by establishing a digital twin for each cell’s electrical identity, it creates an auditable data trail. This supports root cause analysis, warranty management, and compliance with traceability requirements, turning a quality check into a foundation for continuous process improvement and risk mitigation.
Ideal User: Quality control departments and module assembly lines.
When to choose: When traceable electrical testing and cell grading are required for downstream assembly.
