EV Charging Authentication for Automatic Billing and Faster Fill-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for charging electric vehicles are inconvenient and require manual payment approval, lacking automation and efficiency in identifying and billing the vehicle's energy storage device.
Innovation Solution
A method where a motor vehicle's electronic computing device wirelessly transmits an identifier to a charging device when within a predetermined distance, allowing automatic identification of the billing account and debiting for the energy transferred, enabling contactless payment and efficient charging process management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual payment approval is required for charging, then billing accuracy is improved, but charging process efficiency deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-registering user billing information and vehicle identifiers before the charging process. When the vehicle approaches the charging device, the system automatically matches the vehicle identifier with registered users and pre-authorizes the charging session, eliminating the need for manual payment approval during charging while ensuring accurate billing through pre-validated user accounts
2Ease of operation
If automatic identifier recognition is implemented, then charging convenience is improved, but system complexity deteriorates
Solution Approach 1:
The system replaces manual mechanical identification processes (such as physical ticket insertion or manual ID input) with automatic electronic identifier recognition. Sensors and communication modules detect vehicle identifiers automatically when the vehicle approaches the charging device, and the system electronically matches this with registered user data, providing convenient automatic authentication without requiring complex user interaction or manual processes
3Speed
If wireless transmission of identifier is used, then charging speed is improved, but energy consumption deteriorates
Solution Approach 1:
The system employs periodic action by transmitting the vehicle identifier wirelessly only at specific moments - when the vehicle approaches the charging device and at the start of the charging session. The identifier is transmitted periodically at these key points rather than continuously, enabling rapid authentication and charging initiation while minimizing energy consumption by avoiding constant transmission

Data Source
AI summary
A method for filling an energy storage device of a motor vehicle by a charging device involves the motor vehicle being closer to the charging device than a predetermined threshold distance. A billing account associated with the motor vehicle is provided with a clearly identifiable, wirelessly transmitted identifier for the charging device by an electronic computing device of the motor vehicle. The energy storage device is filled by the charging device, and in accordance with the filling and the billing account is automatically debited.
