EV Charging System with Emergency Bypass and Stolen Vehicle Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery charging systems for electric vehicles fail to charge batteries in emergency situations and do not allow for tracing of stolen vehicles, as they rely solely on authentication success for power supply control and do not facilitate charging of stolen vehicles.
Innovation Solution
A battery charging system that includes a network of components such as PLC modems, network termination units, management centers, power plants, and police stations, enabling emergency charging regardless of authentication results and allowing for identification and tracking of stolen vehicles through unique identification and position information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is required for battery charging, then security and authorization are improved, but emergency charging capability deteriorates
Solution Approach 1:
The system performs preliminary classification of charging requests into normal and emergency categories. Emergency charging ports are pre-configured to bypass authentication, allowing immediate charging in critical situations while maintaining security for normal ports through required authentication processes.
Solution Approach 2:
The charging system is segmented into multiple independent charging ports with different authentication requirements. Normal charging ports require authentication for security, while emergency charging ports operate without authentication to ensure availability during critical situations, allowing both security and emergency capability to coexist.
2Device complexity
If authentication results are used only for power supply control, then system simplicity is maintained, but stolen vehicle tracking capability deteriorates
Solution Approach 1:
The authentication result processing system is designed to serve multiple functions: it controls power supply based on authentication outcomes and simultaneously tracks stolen vehicles by monitoring and reporting abnormal charging events to authorities, allowing one system to fulfill multiple purposes without significant complexity increase.
Solution Approach 2:
The system implements feedback mechanisms where authentication results and charging status information are continuously monitored and fed back to a central management system. This enables the system to detect abnormal patterns indicating stolen vehicle usage and automatically report to relevant authorities while maintaining normal operation for legitimate users.

AI summary
A battery charging system includes: an electric vehicle; a network termination unit connectable to the electric vehicle through a power line cable for supplying electric power to the electric vehicle; and a first server that transmits a control signal indicative of permission or forbiddance of power supply from the network termination unit to the electric vehicle to the electric vehicle through the network termination unit. The electric vehicle transmits identification information for identifying the electric vehicle and the user thereof to the first server through the network termination unit. The network termination unit transmits position information concerning the position of the network termination unit to the first server. The first server determines permission or forbiddance of the power supply based on the identification information and the position information.
