Telematics-Based EV Charging User Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electric vehicle charging stations often need to maintain multiple registration and RFID membership cards to access different stations, leading to inconvenience and inefficiency, and existing billing systems struggle to accurately identify and authorize charges without user intervention.
Innovation Solution
A telematics-based system that automates user identification and authorization by aggregating transaction data, including location, time, and charge amount, to determine the charging station used and the user, enabling seamless access and billing without the need for multiple access tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users maintain multiple registration and RFID membership cards to access different charging stations, then access to various charging stations is enabled, but user convenience deteriorates and system complexity increases
Solution Approach 1:
The patent implements a universal telematics-based identification system that replaces multiple charging station-specific access tools (registration forms, RFID cards) with a single vehicle telematics system. The system uses the vehicle's existing telematics infrastructure to automatically identify users and authorize charging sessions at any participating charging station, eliminating the need for users to maintain multiple access tools while preserving access capability across different stations.
Solution Approach 2:
The patent merges the functions of multiple separate access authentication systems into a single unified telematics-based identification system. By combining user identification, vehicle recognition, and charging authorization into one integrated system that leverages the vehicle's existing telematics capabilities, the patent eliminates the need for separate registration and RFID cards for different charging stations, thereby improving user convenience while maintaining universal access.
2Measurement precision
If manual user identification and authorization processes are used at charging stations, then billing accuracy is maintained, but user intervention is required and processing time increases
Solution Approach 1:
The patent implements self-service automation where the vehicle's telematics system automatically performs user identification, charging station location determination, and authorization request transmission without requiring user intervention. The system uses the vehicle's existing telematics infrastructure to automatically identify the user, determine the charging station's location, and transmit authorization requests to the charging station operator, thereby maintaining billing accuracy while eliminating the need for manual user input.
Solution Approach 2:
The patent establishes an automated feedback loop where the telematics system continuously monitors charging session data, automatically transmits usage information to the billing system, and receives authorization confirmations. This automated feedback mechanism ensures billing accuracy by systematically capturing and reporting charging data while eliminating the need for manual user intervention in the authorization process.
3Ease of manufacture
If traditional access tools and manual authorization processes are used, then system implementation is straightforward, but bandwidth usage increases and efficiency decreases
Solution Approach 1:
The patent replaces traditional mechanical access control systems (RFID cards, physical registration forms) with an electronic telematics-based identification system. By substituting the mechanical card-swiping and manual form-filling processes with automated electronic communication through the vehicle's telematics system, the patent reduces physical infrastructure requirements and minimizes bandwidth usage while maintaining ease of implementation through leveraging existing vehicle communication capabilities.
Data Source
AI summary
Systems, methods, and other embodiments associated with identifying a user of a charging station. According to one embodiment, a system includes a communication logic and an authorization logic. The communication logic aggregates transaction data to an authorizing entity. The transaction data is associated with a user and a chargeable vehicle. The authorization logic receives an authorization request to authorize a transaction between the chargeable vehicle and the charging station. The authorization logic sends a response to the authorization request. The communication also enables the chargeable vehicle to receive a charge from the charging station based on the response to the authorization request.
