Solution Overview
Problem
Current vehicle charging systems lack effective validation methods to ensure secure and efficient charging, particularly in scenarios where multiple vehicles and charging stations from different manufacturers interact, leading to potential security risks and inefficiencies in billing and access control.
Innovation Solution
A charge validation system utilizing remote computer processors to compare temporal patterns of electrical parameter values between vehicles and charging equipment, allowing for secure identification and authorization through unique electric key patterns, which can be dynamically updated and validated in a cloud-based system, enabling secure and efficient charging operations without the need for direct communication between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional charging systems allow any vehicle to charge at any station, then ease of operation is improved, but security and billing accuracy deteriorate
Solution Approach 1:
The system continuously monitors and compares electrical parameter patterns between the vehicle and charging equipment, using this feedback to validate authorization and ensure billing accuracy. The comparison of temporal patterns of electrical parameters provides ongoing verification that the charging session is legitimate and properly authorized.
Solution Approach 2:
The patent introduces an intermediary validation mechanism that compares electrical parameter patterns without requiring direct communication between the vehicle and charging equipment. This intermediary comparison process validates authorization while maintaining ease of operation, as users simply need to plug in without additional authentication steps.
2Reliability
If different manufacturers use different hardware systems, then manufacturing precision and device reliability are improved, but adaptability and ease of manufacture deteriorate
Solution Approach 1:
The patent creates a universal validation method that works across different manufacturers' equipment by comparing electrical parameter patterns rather than relying on manufacturer-specific hardware or communication protocols. This universal approach allows any vehicle to charge at any station while maintaining each manufacturer's device reliability standards.
Solution Approach 2:
The system uses changes in electrical parameters (current, voltage, power) over time as the basis for validation, rather than relying on fixed hardware identifiers or communication protocols. This parameter-based approach enables cross-manufacturer compatibility while preserving each device's operational reliability.
3Measurement precision
If direct communication between vehicle and charging equipment is required for validation, then measurement precision and reliability are improved, but device complexity and ease of manufacture deteriorate
Solution Approach 1:
The patent uses electrical parameter patterns as an intermediary that indirectly validates the charging session without requiring direct communication between vehicle and charging equipment. This intermediary approach maintains measurement precision by comparing objective electrical measurements while avoiding the complexity of implementing communication systems in both devices.
Solution Approach 2:
The validation process is self-service in that it automatically compares electrical parameter patterns without requiring active participation or communication from either the vehicle or charging equipment. The system passively monitors and compares the natural electrical flow patterns, eliminating the need for complex communication protocols.
Data Source
AI summary
A charge validation system receives data defining a first temporal pattern of electrical parameter values describing electric power received during a charge event with a vehicle, receives data defining a second temporal pattern of electrical parameter values describing electric power supplied during a charge event with electric vehicle supply equipment, and responsive to mismatch of the first and second temporal patterns, sends a command to the electric vehicle supply equipment to prompt the electric vehicle supply equipment to discontinue or preclude charging.
