Vehicle Charging Authentication via Imaging Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle charging systems require users to manually input authentication information each time, which is inconvenient and increases user workload.
Innovation Solution
A vehicle charging system that includes an imaging device on the vehicle to acquire and send authentication information to the charging equipment, eliminating the need for manual input, and uses an information indicator at the charging equipment to facilitate automatic authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual IC card authentication is used, then authentication security is maintained, but user convenience deteriorates due to repeated manual operations
Solution Approach 1:
The system performs preliminary actions by having the vehicle's imaging device capture authentication information in advance when the vehicle approaches the charging equipment. The authentication information is stored and automatically sent when needed, eliminating the need for repeated manual IC card operations.
Solution Approach 2:
The system creates a copy of the authentication information by capturing it through the imaging device (camera or barcode reader). Instead of requiring the original IC card to be physically present each time, the system uses the copied authentication data stored in the vehicle's terminal device for automatic authentication.
2Loss of time
If authentication information is manually input each time, then authentication accuracy is ensured, but time consumption increases
Solution Approach 1:
The system performs preliminary actions by having the vehicle's imaging device capture authentication information in advance when the vehicle approaches the charging equipment. The authentication information is stored and automatically sent when needed, eliminating the need for repeated manual IC card operations.
Solution Approach 2:
The system enables self-service authentication where the vehicle's terminal device automatically performs the authentication process without user intervention. The imaging device captures information, the sending device transmits it, and the authentication device verifies it all automatically, making the system serve itself rather than requiring manual user operations.
3Ease of operation
If wireless communication is enabled without authentication, then user convenience improves, but system security deteriorates
Solution Approach 1:
The system introduces an intermediary authentication mechanism using the vehicle's terminal device as a mediator between the user and the charging equipment's wireless LAN. The terminal device stores authentication information and automatically transmits it, enabling seamless wireless communication while maintaining security through the intermediary authentication layer.
Solution Approach 2:
The system performs preliminary authentication actions by having the vehicle's imaging device capture authentication information in advance when the vehicle approaches the charging equipment. The authentication information is stored and automatically sent when needed, enabling wireless communication to be enabled seamlessly while maintaining security through pre-established authentication credentials.
