EV Charging Payment Authentication via Secure Remote Commerce
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems face challenges due to varying and incompatible payment systems at different charging stations, requiring cumbersome registration processes and raising data privacy concerns when customers provide payment information to multiple charge point operators.
Innovation Solution
A computer-implemented method and system enable secure remote commerce transactions by establishing a mutually authenticated and encrypted communication session between the electric vehicle and the charging point using a Transport Layer Security (TLS) protocol, retrieving payment credentials from a digital wallet, generating a cryptographically signed payload, and transmitting it via an API for authorization, allowing seamless charging without manual registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different payment systems are used at different charging stations, then each charging station can operate independently with its own payment method, but consumers face compatibility issues and cumbersome registration processes
Solution Approach 1:
The patent implements a universal payment interface that accepts multiple payment methods (credit cards, debit cards, digital wallets) through a single standardized system. The payment terminal is designed to process various card types and digital payment formats without requiring separate registration processes for each payment method, thereby achieving multi-functionality while maintaining simplicity.
Solution Approach 2:
The patent introduces a centralized payment processing intermediary that mediates between different charging stations and various payment systems. This intermediary layer standardizes payment transactions by converting different payment methods into a unified processing format, enabling compatibility across diverse charging infrastructure without requiring consumers to register separately at each station.
2Productivity
If payment information is collected at multiple charging stations, then transactions can be processed at different locations, but data privacy concerns increase
Solution Approach 1:
The patent extracts sensitive payment information from the local charging station environment and transfers it to a secure centralized processing system. By removing payment data collection from individual charging stations and consolidating it in a protected remote environment, the system maintains transaction availability at multiple locations while significantly reducing data privacy risks at each charging point.
Solution Approach 2:
The patent creates a secure, isolated processing environment for handling payment information that is inert to external security threats. Sensitive data is processed in a protected architectural layer that shields it from potential security vulnerabilities in the charging station hardware and software, thereby enabling widespread transaction processing while maintaining data privacy through environmental security isolation.

AI summary
Techniques for enabling secure remote commerce (SRC) transactions for electric vehicle (EV) charging at a charge point (CP) are disclosed. The techniques include establishing a mutually authenticated and encrypted communication session between an EV user system and the CP using transport layer security (TLS). The EV receives merchant information, including a charge point identifier and charge point operator certificate details. The EV retrieves payment credentials from a digital wallet, including a digital card ID assigned by an SRC system. A cryptographically signed payload containing the digital card ID, merchant information, and a timestamp is generated and signed using a private key associated with the EV. The signed payload is transmitted securely to the SRC system via an application programming interface (API). Upon receiving an authorization response approving the payment transaction, the EV transmits a command to the CP to initiate charging.
