BEV Charger Authentication via Location and ID Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery electric vehicles (BEVs) consume significant electricity for charging, leading to increased power consumption and potential unauthorized charging, resulting in higher electricity expenses for household users.
Innovation Solution
A vehicle authentication system using communication devices to selectively associate with a premise system based on location and vehicle identifier, ensuring exclusive charging authorization and optimizing charging through communication with the power grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If BEV vehicles are allowed to charge at charging stations, then charging convenience is improved, but unauthorized charging may occur leading to increased electricity expenses
Solution Approach 1:
The system performs preliminary authentication of the vehicle against the charging station before allowing charging to commence. The communication device verifies the vehicle identifier and location data in advance, ensuring only authorized vehicles can access charging services, thereby preventing unauthorized charging while maintaining convenience for legitimate users
2Loss of energy
If authentication protocols are implemented to prevent unauthorized charging, then electricity expense control is improved, but system complexity increases
Solution Approach 1:
The patent introduces a communication device as an intermediary component that handles authentication between the vehicle and charging station. This dedicated intermediary module simplifies the overall system architecture by centralizing the authentication logic, making the system more manageable despite the added authentication functionality
Solution Approach 2:
The system uses vehicle identifiers and location data as digital copies or representations of the vehicle's identity and position. These data copies enable authentication without requiring physical verification or complex hardware identification systems, reducing overall system complexity while maintaining security
3Measurement precision
If communication devices are used for vehicle authentication, then charging authorization accuracy is improved, but device complexity increases
Solution Approach 1:
The communication device performs multiple functions including authentication, location verification, and charging control within a single integrated component. This multi-functionality reduces the need for separate dedicated devices for each function, thereby limiting the increase in device complexity while maintaining high authorization accuracy
4Reliability
If exclusive association between vehicle and charging station is enforced, then unauthorized charging prevention is improved, but charging accessibility decreases
Solution Approach 1:
The authentication system dynamically evaluates each charging request based on the vehicle's current location and identifier. The exclusive association is not fixed but dynamically established and terminated based on real-time conditions, allowing the system to prevent unauthorized charging while maintaining flexibility and accessibility for authorized vehicles

AI summary
A vehicle system has a first communication device configured to selectively associate with a second communication device of a premise system based on a location of the vehicle with respect to the premise system and a vehicle identification. A charging control system is configured to permit charging of the vehicle in response to the selective association between the first and second communication devices.
