Outlet Power Control Server for Reservation-Free EV Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The prevalence of electric vehicle charging facilities is hindered by high costs and the need for complex infrastructure, including mechanical or electric locks and advance reservation systems, which are costly and burdensome to maintain, especially when using 100V or 200V outlets.
Innovation Solution
A management server and control system that allow for remote control of power supply to outlets via user terminals, enabling secure and efficient charging by acquiring and processing user requests for power supply start and stop times, reducing the need for physical locks and advance reservations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical or electric locks are installed in outlet boxes to prevent electricity stealing, then security against electricity theft is improved, but device complexity and maintenance cost increase
Solution Approach 1:
The patent replaces mechanical lock systems with an electronic control system that uses remote authentication and electronic switching. The management server authenticates users and sends control signals to electronic switches at outlet locations, eliminating the need for physical locks while maintaining security against electricity theft.
Solution Approach 2:
The patent introduces a management server as an intermediary between users and outlet control. The server handles authentication, authorization, and control signal transmission, replacing the need for complex local locking mechanisms while providing centralized security management.
2Ease of operation
If advance reservation systems are implemented for outlet usage, then user management and settlement processing are improved, but device complexity and operational burden increase
Solution Approach 1:
The management server performs multiple functions including user authentication, authorization, control signal transmission, and settlement processing. This multi-functional approach eliminates the need for separate reservation systems while improving ease of operation through centralized management.
Solution Approach 2:
The system enables users to autonomously access outlets through remote authentication via smartphones or other terminal devices. Users can independently initiate charging sessions and receive automated settlement processing, reducing operational burden while improving ease of use.
3Power
If dedicated chargers with high-speed charging functions are installed, then charging performance is improved, but cost increases
Solution Approach 1:
The patent extracts the control and management functions from physical charger infrastructure and consolidates them in a remote management server. This allows existing standard outlets to be utilized while implementing sophisticated charging management, reducing infrastructure cost while maintaining charging performance.
