Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric vehicle charging stations are deployed widely to improve convenience and adoption, then the infrastructure complexity and coordination requirements increase significantly
Solution Approach 1:
A centralized server acts as an intermediary between multiple charging stations and electric vehicles, managing authentication, billing, and charge transfer coordination. This centralizes complexity in the server while keeping individual charging stations relatively simple, resolving the contradiction between widespread deployment and infrastructure complexity.
Solution Approach 2:
The server provides universal functionality across all charging stations, handling authentication, billing, and charge management in a single centralized system. This multi-functional approach allows widespread station deployment without each station needing complex independent capabilities.
2Productivity
If charge transfer is enabled between multiple charging stations to improve efficiency, then the system coordination and communication requirements increase
Solution Approach 1:
The server mediates charge transfers between different charging stations by receiving requests from one station, processing authentication and billing, and directing charge flow to the appropriate vehicle. This intermediary approach enables efficient inter-station charging while centralizing coordination complexity in the server.
Solution Approach 2:
The system segments charging operations into independent station units that can operate autonomously for local charging, while the server handles inter-station coordination. This segmentation allows high productivity at the station level without requiring full system complexity at each station.
3Reliability
If secure communication and access key generation are implemented across the network to improve security, then the communication protocol complexity increases
Solution Approach 1:
The server acts as a secure intermediary that generates and manages access keys for all charging operations. By centralizing security functions in the server, individual charging stations can maintain simpler communication protocols while the system overall achieves high security through the server's key management.

AI summary
A system for controlling a charging of an electric vehicle, wherein a charging at one electric vehicle charging station affect a charging at another electric vehicle charging station is disclosed. The system includes: an electric power grid, a first electric vehicle charging station connected to the electric power grid, and a second electric vehicle charging station connected to the electric power grid, wherein the first electric vehicle charging station facilitates a charge transfer for an electric vehicle at the second electric vehicle charging station using a mobile device. The mobile device relays communication from the electric vehicle charging stations to the cloud server. The charge transfer request received at the cloud server is authorized using identification information and credit account information received from the mobile device. The charge transfer at the first electric vehicle charging station is adjusted based on a charging level at the second electric vehicle charging station.
