Authenticated Non-Contact Vehicle Charging by User Intention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact vehicle charging systems are complex for users, prone to forgotten charging, and can be unauthorized by unregistered individuals due to the lack of user authentication.
Innovation Solution
A non-contact charging system that automatically starts or stops charging based on user intention and authentication, using a power-transmitting unit, an information-obtaining unit, and a charging control device to manage power transmission in response to vehicle operations and user authentication, ensuring only registered users can initiate or stop charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic charging start/stop is implemented based on vehicle operation, then charging convenience is improved, but unauthorized charging by third persons becomes possible
Solution Approach 1:
The patent introduces an authentication unit as an intermediary between the charging control device and the power transmission system. This intermediary verifies user identity through authentication information (such as IC cards or biometric data) before allowing charging operations, thus preventing unauthorized access while maintaining automatic charging functionality for authenticated users
2Reliability
If manual charging operation is required, then charging security is improved, but user operation complexity increases
Solution Approach 1:
The patent implements preliminary authentication action before charging operations. The authentication unit verifies user identity in advance, and the authenticated status is stored and used for subsequent automatic charging decisions. This preliminary action eliminates the need for repeated manual operations while maintaining security through pre-verified user credentials
3Ease of operation
If charging starts automatically without authentication, then charging convenience is improved, but unauthorized access by third persons occurs
Solution Approach 1:
The authentication unit serves as a security intermediary that filters between the automatic charging system and unauthorized access. It verifies user identity through authentication information before allowing the charging control device to initiate power transmission, thereby preventing third-party unauthorized charging while maintaining automatic convenience for legitimate users
4Reliability
If user authentication is implemented, then charging security is improved, but system complexity increases
Solution Approach 1:
The authentication unit is designed with multi-functionality, serving both as a security verification mechanism and as a user identification system for personalized charging preferences. By consolidating multiple functions into a single integrated unit, the patent minimizes additional system complexity while achieving comprehensive security and convenience
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the charging process, prevents forgotten charges, and secures the system by ensuring only authorized users can control battery charging, enhancing convenience and security.
Implementation Method 1
a power-transmitting unit that transmits power to a power-receiving unit in a non-contact manner
Data Source
AI summary
A power-transmitting unit starts transmitting power to a power-receiving unit in a vehicle if (1-1) operation information represents a parking operation of the vehicle and/or (2-1) intention information represents that a user of the vehicle intends to get off the vehicle, and (3) authentication information represents that the user of the vehicle is a registered user. The power-transmitting unit stops transmitting the power to the power-receiving unit if (1-2) the operation information represents a start operation of running of the vehicle and/or (2-2) the intention information represents that the user of the vehicle intends to get in the vehicle, and (3) the authentication information represents that the user of the vehicle is the registered user.
