EV Charging Station Access Control via Mobile QR Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for controlled access to electric vehicle charging stations as their usage increases, with existing systems lacking efficient methods to authenticate and authorize consumers for charging capabilities.
Innovation Solution
A method and system that involve registering a unique identifier of a mobile device with an electric vehicle charging station operator, transmitting a readable code associated with the charging station, and verifying the consumer's access rights, using a computer processor and memory to authorize access based on the unique identifier and readable code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If controlled access is implemented for electric vehicle charging stations, then security and authorization management are improved, but system complexity and authentication requirements increase
Solution Approach 1:
The patent introduces a server as an intermediary component that centralizes the authentication logic. The server receives the readable code from the mobile device, verifies it against stored charging station information, and communicates authorization status to the charging station. This mediator approach improves security by centralizing control while reducing the complexity burden on individual charging stations and mobile devices.
Solution Approach 2:
The patent uses a readable code (such as a QR code) that is a simplified copy or representation of the charging station's identification and authorization information. Instead of requiring complex cryptographic handshakes or physical tokens, the system uses a visual code that can be easily captured by a mobile device camera and processed by the server, thereby improving security while maintaining ease of operation.
2Reliability
If authentication verification is performed for each charging session, then access control security is improved, but user convenience and charging speed are reduced
Solution Approach 1:
The patent implements preliminary action by having users register their mobile devices with the charging station operator in advance. The server stores the association between the mobile device's readable code and the user's account information before the charging session begins. When the user arrives at the charging station, the authentication process is greatly accelerated because the verification data is already prepared and stored, reducing on-site authentication time while maintaining security.
3Reliability
If readable code transmission is required for authorization, then access control reliability is improved, but ease of operation and user convenience are worsened
Solution Approach 1:
The patent replaces traditional mechanical or manual authentication methods (such as physical cards, keys, or manual code entry) with an optical/electronic system. The readable code is displayed visually and captured by the mobile device's camera, then transmitted electronically to the server for verification. This substitution maintains high reliability through secure code verification while dramatically improving ease of operation, as users simply need to point their camera at the code rather than manually input information or handle physical tokens.
