Battery Pack Bonding Diagnosis with Thermal-Magnetic Imaging

The patent combines thermal image reading and magnetic field image reading into a unified diagnosis system. The bonding state is determined by integrating both thermal data (indicating abnormal connections) and magnetic field data (indicating normal connections), thereby improving diagnosis precision while maintaining process simplicity through a coordinated multi-modal approach.

The patent integrates magnetic field image reading with thermal image reading to create a comprehensive diagnosis system. Magnetic field data provides information about normal connections, which complements the thermal data, thereby improving overall diagnosis precision while keeping the process manageable through systematic integration.

The patent divides the diagnosis process into distinct sequential stages: thermal image reading, magnetic field image reading, and integrated analysis. Each stage handles specific data types and processing tasks independently, then combines results in a structured manner. This segmentation reduces system complexity by organizing the multi-modal integration into manageable, modular components.

The patent merges the inspection of hundreds of battery cells and wires into a single batch process using thermal and magnetic field imaging. Instead of individually inspecting each connection, the system captures comprehensive thermal and magnetic field data across the entire battery pack simultaneously, then processes the data to identify bonding states of all connections in one unified analysis, dramatically reducing inspection time while maintaining precision.
