Portable EV Charging Control Using Existing AC Power Outlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and limited accessibility of electric vehicle (EV) charging infrastructure hinder the widespread adoption of EVs due to the need for expensive power supply facilities and complex operation procedures, with existing EV chargers often requiring specific installation and payment methods, and lacking compatibility with low-power AC power supplies.
Innovation Solution
A portable EV charging device that uses a commercial AC power supply, equipped with an AC plug and a connector conforming to a predetermined standard, which communicates with a charging management server to control power supply operations, determining permission for power delivery based on user authentication and location, allowing charging at existing power facilities without the need for new installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive dedicated power supply facilities are installed for EV charging, then charging reliability is improved, but installation cost increases significantly
Solution Approach 1:
The system allows ordinary power supply facilities to serve EV charging needs without requiring specialized infrastructure. The charging device autonomously manages power reception and transmission, enabling self-service charging at regular outlets while maintaining reliability through centralized control and authentication mechanisms.
2Reliability
If centralized control system is implemented for power supply management, then unauthorized use prevention is improved, but system complexity increases
Solution Approach 1:
A centralized control system acts as an intermediary between power supply facilities and charging devices. This mediator manages authentication, authorization, and power supply control, preventing unauthorized use while maintaining relatively simple individual device designs through standardized communication protocols.

AI summary
An information processing device includes an acquisition unit that acquires information related to a charging device that receives power from a power supply facility and supplies the power, the charging device being separated from the power supply facility; a determination unit that determines permission or non-permission of the power supply of the charging device based on the information related to the charging device; and a transmission unit that transmits information related to a determination result of permission or non-permission of the power supply to the charging device or another device that controls the charging device.
