Battery Vibration Diagnosis for Connector Failure Detection

The patent applies preliminary action by measuring vibration values and diagnosing connection states before actual connection failures occur. The system continuously monitors vibration in X, Y, and Z directions and compares against reference values to detect potential connection issues early, allowing preventive maintenance before micro-short circuits or complete failures happen.

The patent implements feedback by continuously measuring vibration values from connected battery packs and using this information to diagnose connection states. The control unit receives vibration data, compares it with reference values, and provides feedback on connection reliability, enabling real-time monitoring and diagnosis of potential connection failures in multi-battery configurations.

The patent applies self-service by having the battery packs monitor their own vibration and connection states. Each battery pack or module includes its own vibration sensing capability, allowing the system to self-diagnose connection issues without requiring external complex testing equipment. The system uses the existing structural vibration characteristics to assess connection health.

The patent replaces complex mechanical connection testing with vibration-based diagnostic methods. Instead of physically inspecting or mechanically testing connector integrity, the system uses vibration sensors to detect changes in vibration characteristics that indicate connection problems, substituting mechanical inspection with a more sophisticated but less intrusive sensing approach.

The patent implements continuity of useful action by performing vibration measurements continuously or at regular intervals in all three axial directions simultaneously. Rather than sequential measurements that would take more time, the system continuously monitors vibration in X, Y, and Z directions, ensuring that connection issues are detected promptly without significant time loss.

The patent applies partial action by focusing vibration measurement efforts on the three critical axial directions (X, Y, Z) that are most relevant to connection failure modes. Instead of measuring all possible vibration parameters or using overly complex measurement schemes, the system concentrates on the essential directional components that provide sufficient diagnostic information for connection reliability assessment.
