Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to ensure that only authorized electric vehicles can be charged and to manage charging operations based on vehicle information, as infrastructure for electric vehicles grows.
Innovation Solution
An apparatus and method that includes an electric vehicle port with sensors and a computing device to detect and verify the attachment and identification data of the vehicle, determining authorization status through a verification process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If charging infrastructure grows to accommodate more electric vehicles, then charging accessibility is improved, but the risk of unauthorized charging and system security issues increases
Solution Approach 1:
The system performs preliminary actions by detecting vehicle attachment through sensors before charging begins, verifying authorization status through computing devices, and establishing communication protocols in advance. This ensures that only authorized vehicles receive power, preventing unauthorized charging while maintaining infrastructure accessibility.
2Reliability
If sensor and computing device systems are added to verify authorization, then charging security is improved, but device complexity increases
Solution Approach 1:
The charging port assembly integrates multiple functions into a single system: mechanical connection, sensor-based attachment detection, communication protocol handling, and authorization verification. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while maintaining security.
3Measurement precision
If attachment detection and verification processes are implemented, then charging control accuracy is improved, but the charging process time increases
Solution Approach 1:
The system implements efficient detection and verification processes that quickly skip through attachment detection, data exchange, and authorization verification steps. By optimizing the sequence and speed of these operations, the system achieves accurate vehicle identification and authorization confirmation without significantly extending the overall charging setup time.
Data Source
AI summary
A connector for charging an electric vehicle that includes a housing configured to mate with an electric vehicle port of an electric vehicle, at least a sensor configured to detect an attachment datum as a function of the housing mating with an electric vehicle port, and transmit the attachment datum to a computing device, a computing device configured to receive the attachment datum from the at least a sensor, receive an identification datum from the electric vehicle, generate a verification datum as a function of the identification datum and the attachment datum, and determine an authorization status as a function of the verification datum.
