Electric Vehicle Battery Charging Authorization via Local ID Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric-powered vehicle theft prevention systems are costly and ineffective due to the need for external authentication devices and networks, and they fail to prevent charging at unauthorized facilities, allowing thieves to freely charge stolen vehicles.
Innovation Solution
An electric-powered vehicle with a charging request section, storage section, and charging facility information acquisition section that only allows charging at pre-permitted facilities, using either facility IDs or GPS-based location verification to restrict battery charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external authentication devices and networks are used to prevent theft, then theft prevention capability is improved, but system cost and complexity increase enormously
Solution Approach 1:
The patent extracts the authentication function from external devices and networks, and relocates it entirely within the vehicle's own control unit. The control unit stores authentication information locally and performs self-authentication when a charging request is received, eliminating the need for external authentication infrastructure while maintaining theft prevention capability.
Solution Approach 2:
The vehicle's control unit performs self-authentication using authentication information stored within itself. When a charging request is received, the control unit independently verifies whether the requesting charging facility is authorized without needing to communicate with external authentication servers, thereby simplifying the system while maintaining security.
2Reliability
If external authentication devices and networks are used to prevent theft, then theft prevention capability is improved, but construction and operation costs increase enormously
Solution Approach 1:
The patent removes the expensive external authentication infrastructure (authentication devices, networks, and associated facilities) and replaces it with a lightweight local authentication system within the vehicle. This dramatically reduces construction and operation costs while maintaining the core theft prevention function.
Solution Approach 2:
The patent replaces expensive, permanent external authentication infrastructure with a simple, inexpensive local authentication system embedded in the vehicle's control unit. The authentication information is stored locally and used without requiring costly external facilities, making the system economically viable.

AI summary
An electric-powered vehicle is provided which is capable of charging a battery with stability, and which is capable of limiting the charging of the battery in the event of theft to provide a high degree of effectiveness of preventing theft by using a simple configuration. In the electric-powered vehicle, a vehicle storage section stores therein information, e.g. an ID list, about charging facilities permitted to charge a vehicle-mounted battery. When the electric-powered vehicle is connected to a charging facility, a charging facility ID acquisition section acquires the ID of the charging facility from the charging facility connected thereto. When it is judged that the ID of the charging facility acquired by the charging facility ID acquisition section is included in the ID list of charging facilities stored in the vehicle storage section, a charging request section makes a request to the charging facility for charging of the vehicle-mounted battery.
