EV Charge Station Credential Update System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle charge station network systems face challenges in securely and efficiently updating network access credentials for electric vehicles, which is essential for security and bandwidth management, as current methods lack a systematic approach to manage credential changes over time.
Innovation Solution
A network access credential updating system that receives requests from charge station operators to update credentials, communicates new credentials to vehicles, and updates the network accordingly, with a credential update agreement allowing for controlled timing of updates to ensure security and minimize disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network access credentials are updated frequently for security reasons, then network security is improved, but vehicle charging operations may be disrupted
Solution Approach 1:
The system performs preliminary actions by notifying vehicles of upcoming credential changes in advance through a credential update agreement. This allows vehicles to prepare for the transition before it occurs, ensuring they can connect to the network with updated credentials without interruption to charging operations.
Solution Approach 2:
The patent introduces an intermediary credential update agreement that mediates between the network security requirements and vehicle charging operations. This agreement acts as a buffer, coordinating the timing and method of credential updates to maintain both security and operational continuity.
2Reliability
If network access credentials are changed over time for security reasons, then network security is enhanced, but system complexity increases
Solution Approach 1:
The system implements self-service by enabling vehicles to automatically receive and process credential update notifications through the credential update agreement. Vehicles autonomously manage their own credential updates without requiring manual intervention, reducing the complexity of centralized credential management.
Solution Approach 2:
The patent employs periodic action through scheduled credential updates defined in the credential update agreement. Instead of ad-hoc updates, credentials are changed at predetermined intervals or times, making the system more predictable and easier to manage despite the increased security requirements.
3Reliability
If credentials are updated immediately without notice, then network security is improved, but vehicles cannot connect to networks smoothly
Solution Approach 1:
The system performs preliminary notification to vehicles about upcoming credential changes through the credential update agreement. This advance notice allows vehicles to prepare for the transition, ensuring smooth connection to networks with updated credentials while maintaining security through timely updates.

AI summary
A network access credential change request is received onto a network access credential updating system. The network access credential change request is a request to update access credentials of a network near a vehicle charge station. The new credential in the request is communicated to an electric vehicle. The network is updated with the network access credential. The vehicle is able to connect to the network with the updated credential after the network has been updated. In one embodiment, the network access credential updating system includes an application. A charge station operating entity communicates a network access credential change request for a particular network to the application. After sending the request, the charge station operating entity updates the network access credential for the network in accordance with a credential update agreement. The credential update agreement tends to afford adequate opportunity for vehicles to receive updated credentials before networks are updated.
