Vehicle Battery Authentication Using Physical Property Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems are inadequate in effectively detecting unauthorized battery replacement in battery-powered vehicles, particularly in rental or leased vehicles where there is a high risk of replacing genuine batteries with non-genuine or inferior products.
Innovation Solution
A determination system that includes a sensor to measure physical properties of the target battery and an information processing apparatus connected to the sensor. The apparatus acquires vehicle identification information, first battery identification information corresponding to the vehicle, physical properties of the target battery, second battery identification information corresponding to these properties, and compares these to determine the authenticity of the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If battery replacement is allowed for maintenance purposes, then battery productivity and vehicle availability are improved, but the risk of unauthorized replacement with non-genuine batteries increases
Solution Approach 1:
The system performs preliminary registration of genuine battery identification information and physical properties in a database before the battery is installed in the vehicle. This preliminary action enables subsequent verification of battery authenticity by comparing measured properties against the registered data, allowing maintenance personnel to replace batteries freely while maintaining security through pre-established reference data.
Solution Approach 2:
The system implements a feedback mechanism where the authentication result (match or mismatch between measured and registered battery properties) is provided back to the user. This feedback loop enables real-time verification of battery authenticity during maintenance operations, allowing immediate detection of unauthorized replacements while permitting legitimate battery changes.
2Reliability
If battery authentication systems are implemented, then detection of unauthorized replacement is improved, but device complexity increases
Solution Approach 1:
The battery authentication system is designed to be self-service, where the battery itself contains identification information and physical property characteristics that enable its own authentication. The measurement device simply reads these inherent battery properties and compares them against registered data, eliminating the need for complex active authentication components within the battery and simplifying the overall system structure.
Solution Approach 2:
The system uses a database as an intermediary component to store and manage the relationship between battery identification information and physical properties. This intermediary allows the measurement device and authentication logic to be separated, with the database serving as the central reference, thereby reducing the complexity of direct point-to-point authentication connections and enabling modular system design.
3Measurement precision
If multiple measurement parameters are used for battery authentication, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The measurement device is designed with multi-functionality, capable of measuring multiple battery physical properties (inductance, resistance, voltage, current) using a single integrated system. This universal approach allows the same device to collect various authentication parameters without requiring separate specialized instruments for each measurement, thereby improving authentication precision while controlling device complexity through consolidation.
