The S37-48-100A
ODM Cell Grading Machine is a high-precision, intelligent testing system engineered for the lithium battery manufacturing industry, offering automated formation and capacity grading with exceptional accuracy and reliability. Designed around the core philosophy of "Intelligent Testing + Automated Grading," this equipment ensures consistent performance across 48 independent channels, making it ideal for production lines requiring scalable, precise battery evaluation. Whether used in electric vehicle (EV)
Battery Assembly, energy storage systems, or consumer electronics, the machine delivers robust results through advanced control mechanisms and real-time data analysis. This automated battery tester integrates an STM32-based microcontroller system that enables seamless operation from initial charge-discharge cycles to final classification. Each channel operates independently—powered by dedicated constant current and voltage sources—ensuring no interference between cells during testing. This modular architecture supports single-point isolation, allowing individual batteries to be monitored without affecting adjacent units, which significantly improves test integrity and process efficiency. The system also features power failure protection: if electricity is interrupted, the unit automatically resumes from where it left off, minimizing downtime and preserving data continuity. Key features include four-wire contact impedance measurement for accurate voltage sensing, software-calibrated charging and discharging currents per channel, and full support for start, stop, pause, and resume functions—all managed via either a built-in keyboard panel or connected computer interface. Test parameters such as voltage, capacity, internal resistance, and temperature are recorded and visualized in real time, enabling comprehensive quality assurance throughout the battery lifecycle. All collected data can be saved locally or transferred via USB-to-485 communication protocols, supporting integration into larger factory automation ecosystems. The physical design emphasizes practicality and flexibility. With a standard gray-white or gray-black casing, 84mm fixture spacing, and options for flat-head connectors or alligator clips, the device accommodates various cell formats including cylindrical, prismatic, and pouch types. Manual loading is supported alongside motor-driven upward pushing mechanisms, ensuring ease of use while maintaining safety standards. Its compact footprint makes it suitable for both small-scale labs and large-volume production environments. Ideal for battery manufacturers seeking precision in formation testing and efficient sorting based on capacity thresholds, this system streamlines the grading process—reducing human error and increasing throughput. It’s particularly valuable in applications demanding strict compliance with international safety and performance benchmarks, such as those required by IEC, UL, or UN certification bodies. Users consistently praise its intuitive interface, stable operation under continuous load, and minimal maintenance needs. Many report significant improvements in product consistency and reduced waste due to more accurate cell categorization compared to manual methods. While some early adopters noted a learning curve when integrating with existing SCADA systems, most found the technical documentation and remote support accessible and effective. Common questions often revolve around compatibility with different battery chemistries (e.g., NMC, LFP, NCA), scalability beyond 48 channels, and integration with MES platforms. The system supports multiple chemistries out of the box and offers ODM customization for unique process requirements. For users considering expansion, additional modules can be added to increase channel count while maintaining synchronization across the entire array. Software updates are regularly released to enhance functionality, improve diagnostics, and ensure long-term usability. In summary, the S37-48-100A represents a smart investment for any battery producer aiming to elevate their manufacturing standards through automation, intelligence, and precision. It bridges the gap between traditional manual testing and modern Industry 4.0 practices, delivering measurable gains in productivity, quality control, and operational resilience.
