Wireless Power Supply Device Vehicle ID Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact power supply systems for electric vehicles do not effectively detect and manage power failures, failing to identify vehicles that were being supplied power during a power outage.
Innovation Solution
The system records vehicle identification information during power supply and cross-checks it with information transmitted from the vehicle, allowing the power supply device to determine if a power failure occurred and which vehicle was affected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle identification information is recorded during power supply to enable power failure detection, then the ability to detect and manage power failures is improved, but the device complexity increases due to additional recording and cross-checking mechanisms
Solution Approach 1:
The system records vehicle identification information in advance during the power supply preparation phase, before actual power delivery begins. This preliminary recording enables rapid power failure detection without requiring complex real-time monitoring systems, as the recorded ID can be directly compared with post-failure vehicle information.
Solution Approach 2:
The system implements a feedback mechanism by cross-checking the pre-recorded vehicle identification information with the vehicle information transmitted after power failure. This feedback loop confirms whether the vehicle that was being supplied power has returned, enabling reliable power failure detection and management while using simple comparison logic rather than complex analysis.
2Measurement precision
If the system cross-checks recorded vehicle identification information with transmitted vehicle information to identify target vehicles, then the precision of identifying affected vehicles is improved, but the loss of time increases due to the additional cross-checking process
Solution Approach 1:
The system creates a copy of the vehicle identification information during the power supply preparation phase and stores it in the power supply device. This copy enables rapid comparison with the vehicle's transmitted information after power failure, achieving high identification accuracy without requiring complex real-time verification processes.
Solution Approach 2:
By performing the information recording action in advance during power supply preparation, the system eliminates the need for time-consuming data collection and analysis after power failure occurs. The pre-recorded identification information is immediately available for comparison, minimizing the time loss while maintaining high identification precision.

Data Source
AI summary
A non-contact power supply system supplies power in a non-contact manner from a power transmission coil of a vehicle to a power reception coil of a power supply device. The power supply device has a power supply side recording means unit records information, a power supply side communication unit that communicates with the vehicle, and a power supply side controller that controls the power output from a power source to the power transmission coil. Vehicle identification information is recorded to the power supply side recording unit during the power supply or during preparation for the power supply to the power reception coil. The power supply side controller cross-checks the vehicle identification information and vehicle information transmitted from the vehicle when the power supply to the power reception coil is stopped before the power supply to the power reception coil is ended normally.
