EV Charger Sharing Server for Reservation and Usage Billing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited availability of electric vehicle chargers outside of private residences poses a challenge for widespread adoption, as existing solutions do not facilitate the sharing or lending of chargers to non-owners.
Innovation Solution
A charger using system comprising a server and terminals that allow users to request and pay for charger usage, with features for calculating and presenting claim and payment prices, managing charger usage, and enabling reservations, thereby facilitating the sharing and lending of chargers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chargers are installed only for people owning and using electrically driven vehicles, then charger ownership is ensured, but charger availability to the general public is limited
Solution Approach 1:
The patent introduces a server as an intermediary that manages charger reservations and usage. The server receives reservation requests from users, manages charger allocation, and coordinates between charger owners and users, enabling public access while maintaining organized management of limited charger resources
Solution Approach 2:
The charger system is designed to serve multiple functions: it can be reserved by multiple users, used by different types of electrically driven vehicles, and managed through a centralized server that handles both ownership rights and public access, making the charger universally accessible while maintaining reliable ownership
2Productivity
If charging stations do not increase all over the country, then existing infrastructure costs are avoided, but vehicle charging accessibility is insufficient
Solution Approach 1:
The patent segments the charger resource into reservable time slots and allocates them to different users through the server. This allows a single charger to serve multiple users at different times, effectively increasing the charging capacity without requiring physical multiplication of chargers across the country
Solution Approach 2:
The system adds the time dimension to charger utilization by implementing reservation functionality. Instead of only increasing the number of chargers spatially, the system maximizes usage efficiency by allowing temporal sharing, effectively increasing charging capacity through time-based allocation
3Adaptability or versatility
If chargers are made widely available through sharing, then charger accessibility is improved, but management complexity increases
Solution Approach 1:
The server acts as an intermediary that centralizes the management of charger reservations, user authentication, and usage coordination. This intermediary handles the complexity of managing widespread charger access, allowing individual chargers to remain simple while the overall system achieves wide accessibility through centralized control

AI summary
In the present invention, when a charging device (2) is used, a terminal (31) acquires an II) for the charging device (2) and transmits a use request and the ID for the charging device (2). A server (4) receives the use request and the ID, calculates a billing fee for the charging device (2) in response to the reception of the use request, and presents the billing fee to the terminal (31). The server (4) calculates an electricity charge incurred for the use of the charging device (2) in response to the reception of the use request. The server (4) calculates a payment fee that includes the calculated electricity charge and a charging device installation charge and presents the payment fee to a terminal (32).
