The
Lithium Battery Testing Equipment SF37-36-200A Power Battery Grading Cabinet is a high-precision, intelligent solution designed for advanced
Battery Formation, grading, and quality assurance in modern manufacturing environments. Engineered with safety, efficiency, and scalability at its core, this system ensures accurate voltage and capacity measurements while supporting automated production lines across industries such as electric vehicles, energy storage systems, e-bikes, and portable electronics. This state-of-the-art battery testing station leverages independent constant current/voltage sources per cell to eliminate interference between units during simultaneous charging or discharging cycles—a critical advantage over conventional multi-cell testers. Its split-type measurement design isolates the power supply from the fixture, significantly reducing risks when handling zero-voltage batteries, making it ideal for industrial settings where operational safety is paramount. The inclusion of STM32 microcontroller technology enables dual-mode operation—either through an intuitive front-panel interface or via computer integration—allowing real-time data visualization, curve tracing, historical comparison, and customizable report generation in multiple formats. Key features include a four-wire test interface for precise resistance-free measurements, modular architecture for simplified maintenance and future upgrades, and a proprietary energy feedback system that returns discharged energy back to the grid—boosting overall system efficiency and minimizing thermal waste. With built-in anomaly protection, barcode scanning capabilities, remote firmware updates, and support for up to 256 test cycles with 32 customizable process steps, this unit supports complex battery evaluation protocols tailored to specific product requirements. Designed for seamless integration into smart factory ecosystems, the SF37-36-200A can connect directly to MES (Manufacturing Execution Systems), enabling end-to-end traceability from raw material input to final shipment. This makes it particularly valuable for manufacturers aiming to improve batch consistency, reduce defects, and meet stringent international standards for lithium-ion battery performance and reliability. In application scenarios ranging from high-volume cell sorting to precision grading for EV battery packs, the equipment delivers rapid, repeatable results—often within sub-100 milliseconds per cycle—while maintaining exceptional accuracy in voltage, current, and capacity readings. Whether used for pre-shipment verification, R&D validation, or production line optimization, this grading cabinet enhances both productivity and product uniformity across diverse battery chemistries including NMC, LFP, and cobalt-based cells. Users consistently praise the system’s robustness under continuous cycling, ease of use, and clear visual feedback on the LCD display, which allows operators to monitor live parameters such as charge/discharge rates, temperature trends, and cumulative capacity. Many also highlight how the natural air-cooled design contributes to long-term stability and minimal downtime—even during extended testing sessions involving hundreds of cells daily. Common questions often revolve around compatibility with different battery sizes, software customization options, and energy recovery efficiency. The device supports various cell formats and configurations, and the flexible software environment allows users to define custom test profiles based on industry-specific needs. Energy feedback typically achieves over 85% return efficiency, aligning with green manufacturing goals and reducing utility costs over time. Whether you're optimizing battery performance in mass production or ensuring consistent quality in specialized applications, the SF37-36-200A stands out as a reliable, safe, and future-ready tool for any battery testing and sorting workflow.
