Vehicle Battery Authenticity Verification Using Physical Property Sensing

The system performs preliminary registration of genuine battery information (identification information and physical property values) in a database before the battery is installed in a vehicle. When battery replacement occurs, the system measures the physical properties of the replacement battery and compares them against the pre-registered values to verify authenticity, thus preventing unauthorized replacement while allowing legitimate changes.

The system continuously monitors battery physical properties through sensors and provides feedback by comparing measured values against registered reference values. When a discrepancy is detected indicating unauthorized replacement, the system generates alerts and notifications to relevant parties, creating a closed-loop verification system that maintains reliability while permitting authorized operations.

The verification system utilizes the battery's own inherent physical properties (such as inductance, resistance, or other electrical characteristics) as identification markers. These properties are naturally present in the battery and require no additional hardware embedded in the battery itself. The system measures these existing properties and compares them against registered values, allowing verification without adding complexity to the battery unit.

The system employs general-purpose sensors and processing units that can serve multiple functions: monitoring battery health, verifying authenticity, and tracking battery performance. By using multi-functional components rather than dedicated verification-only hardware, the system achieves reliable authentication while minimizing the increase in overall device complexity.

The system measures and registers the physical property values of genuine batteries during or after manufacturing while the batteries are still under controlled conditions. These baseline measurements capture the actual properties of each battery unit. During operation, the system compares real-time measurements against these pre-established references, allowing for natural manufacturing variations while detecting deviations that indicate replacement with non-genuine batteries.

The system utilizes multiple physical property parameters (such as inductance, resistance, capacitance, or frequency characteristics) to identify batteries. By measuring several parameters rather than relying on a single tight-tolerance dimension, the system reduces the impact of manufacturing variations on any single measurement while maintaining high verification accuracy through multi-parameter comparison against registered profiles.
