Inductive Charging Foreign Object Detection Self-Test

The system performs preliminary testing of the detector by introducing a known disturbance (test object) before actual operation. This preliminary action verifies the detector's functionality in advance, ensuring reliability without requiring redundant sensor systems during normal operation.

The detector performs self-diagnosis by testing its own functionality through introducing a predetermined disturbance and evaluating its own detection response. This self-service capability ensures operational reliability while eliminating the need for external redundant monitoring systems.

Instead of continuous monitoring, the system performs periodic diagnosis by introducing disturbances at specific intervals (e.g., before charging operations). This periodic approach detects gradual sensor deterioration while minimizing impact on operational time.

The diagnosis is performed preliminarily before actual power transmission operations. By testing detector functionality in advance and storing baseline data, the system can detect deterioration trends without requiring continuous monitoring during critical charging operations.

The diagnosis process is segmented into distinct phases: introducing a predetermined disturbance, detecting the disturbance, evaluating the detection signal, and comparing with reference values. This segmentation allows comprehensive testing using a single standardized test object rather than requiring multiple different test objects.

Instead of using multiple test objects with different physical characteristics, the system achieves comprehensive diagnosis by changing parameters of a single test scenario - introducing a predetermined disturbance with known characteristics and evaluating the detector's response against reference detection signals. This parameter-based approach maintains measurement precision while reducing device complexity.
