Charging Communication System for EV Wall Box Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems do not allow for efficient sharing and utilization of wall boxes by third parties without direct contact with the owner, limiting access to charging options, especially in regions with limited service.
Innovation Solution
A charging communication system comprising a back end server and wall boxes with communication units, enabling users to create communities, share charging options, and manage availability through terminal devices and applications, allowing indirect provision and booking of charging services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wall boxes are privately owned and used only within one household, then ownership control is maintained, but access to charging options is limited
Solution Approach 1:
A backend server acts as an intermediary between wall box owners and users. The backend receives availability information from wall boxes via communication units and makes this information accessible to users through applications on terminal devices, enabling third-party access without direct contact between owner and user.
Solution Approach 2:
The system separates functions into distinct components: wall boxes with communication units that provide availability information, a backend server that processes and stores this information, and user applications that display and enable booking. This segmentation allows each component to operate independently while contributing to the overall sharing functionality.
2Ease of operation
If direct personal consultation is required between wall box owner and user, then trust and coordination are established, but ease of operation is reduced
Solution Approach 1:
The wall box system enables self-service operation where availability information is automatically transmitted from the wall box to the backend and then to users through applications. Users can independently view availability and book charging slots without needing to contact the owner directly, eliminating the need for personal consultation while maintaining information accuracy.
3Loss of information
If charging information is decentralized across multiple wall boxes, then system autonomy is maintained, but information efficiency is reduced
Solution Approach 1:
The backend server merges information from multiple decentralized wall boxes into a centralized database. Each wall box transmits its availability information to the backend, which consolidates this data and makes it uniformly accessible to all users through the application, improving information efficiency while maintaining a manageable system architecture.
