Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle charging systems lack secure and efficient authentication and payment mechanisms, leading to potential unauthorized charging and cumbersome payment processes.
Innovation Solution
Implementing a multi-level authentication process using wireless communication between vehicles, charging stations, and authentication servers, which establishes and verifies parameters such as frequency, voltage, date, time, location, and content requirements for secure charging authorization, and an automatic payment mechanism through a relational database for seamless financial transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-level authentication process is implemented, then security against unauthorized charging is improved, but system complexity increases
Solution Approach 1:
The authentication process is divided into multiple distinct levels: initial authentication between vehicle and charging station, parameter authentication with the authentication server, and payment authentication. Each level handles specific security requirements independently, making the complex security system manageable and maintainable while ensuring comprehensive protection against unauthorized charging.
Solution Approach 2:
An authentication server is introduced as an intermediary component between the vehicle and charging station. This mediator handles parameter verification and authentication logic centrally, reducing the complexity burden on individual charging stations while maintaining high security standards through centralized control and verification.
2Ease of operation
If automatic payment mechanism is implemented, then ease of operation is improved, but system complexity increases
Solution Approach 1:
User payment information and authorization are obtained in advance during the initial authentication phase. The system stores payment credentials and user authorization tokens beforehand, enabling automatic deduction of charging costs without requiring user intervention during the actual charging process. This preliminary setup simplifies the user experience while the backend handles the complexity of payment processing.
Solution Approach 2:
The payment system operates autonomously by automatically deducting charges from pre-registered user accounts based on charging consumption. The system self-manages payment verification, transaction recording, and billing without requiring manual payment actions from users, thereby improving ease of operation while the underlying payment infrastructure handles the systematic complexity.
3Reliability
If multiple parameters are verified during authentication, then reliability is improved, but time consumption increases
Solution Approach 1:
The authentication process is structured as a sequence of periodic verification stages: initial vehicle identification, parameter verification, and payment authorization. Each stage completes its verification task efficiently before transitioning to the next, allowing multiple parameters to be checked systematically without excessive time consumption. The periodic structure ensures thorough verification while maintaining a predictable and manageable authentication timeline.
