The S33-256-10A Energy Feedback Battery Grading System is a high-precision, intelligent apparatus designed for the accurate sorting and analysis of lithium-ion battery cells during formation and capacity grading processes. Engineered for industrial-scale battery production lines, this advanced cell testing solution integrates real-time voltage and capacity measurement with automated grading, data visualization, and seamless integration into manufacturing execution systems (MES). With support for up to 256 independent channels—each equipped with dedicated constant current and voltage sources—the system ensures stable, precise performance without cross-channel interference. Its patented energy recovery technology feeds discharged power back into the facility’s AC grid, significantly reducing operational costs and enhancing sustainability in battery manufacturing environments. This comprehensive battery testing machine features an intuitive graphical user interface that simplifies operation for technicians and engineers alike. Built around an STM32 microcontroller, it delivers exceptional measurement accuracy: ±(0.5‰ reading + 0.5‰ full scale) for both voltage and current. The modular design includes programmable 8/16-channel control modules, bidirectional AC/DC inverters, and flat-head fixtures for secure battery placement, enabling efficient handling of various cell formats. Each channel supports individual start, stop, pause, resume, and protection functions, ensuring safety and process continuity even under unexpected interruptions like power outages. Key advantages include automatic calibration of charging and discharging currents via software, 32-step process programming, and up to 256 cycles per test sequence. With 13 built-in safety protections—including overvoltage, overcurrent, short-circuit, and temperature monitoring—the system safeguards both equipment and personnel. Data collection capabilities allow users to generate detailed discharge and charge curves, facilitating root cause analysis and quality assurance. Integration with MES platforms enables real-time data sharing across production floors, supporting smart factory initiatives and digital transformation strategies. Ideal for manufacturers involved in lithium
Battery Pack Assembly, EV battery development, or energy storage solutions, this battery grading instrument streamlines cell sorting based on performance metrics such as capacity consistency, internal resistance, and voltage stability. It is especially suited for applications requiring high throughput, repeatability, and compliance with international standards like IEC 62660 or UN38.3. Whether used in R&D labs or mass production facilities, the S33-256-10A enhances productivity while minimizing waste through precise classification of battery cells by performance tier. Users consistently praise its reliability, ease of use, and robustness in demanding industrial settings. Many report reduced manual labor due to automation, improved product uniformity, and better traceability thanks to integrated logging and curve generation.
