The main business is lithium battery management systems (BMS), which integrate independent R&D design, production testing, and reliability testing. They are mainly used in low-speed electric vehicles, AGV/AMR, agricultural drones, energy storage and other fields. The product performs online real-time monitoring of the status of lithium battery packs and cells to achieve fault warning, fault location, status assessment, and remaining service life prediction. This improves the reliability and safety of lithium battery system operation and realizes battery system fault prediction and health management.
