Integrated Wireless Charging Fee Collection for Electric Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for electric vehicles (EVs) require separate visits to charging stations for payment and charging, leading to inefficiencies and inconvenience, especially when using dynamic electric vehicle charging (DEVC) on highways, where a method for fee collection is lacking.
Innovation Solution
An apparatus and method that integrate toll fee and charging fee collection for EVs while driving, using an electric power receiver, controller, and toll fee payment processor to transmit and process accumulated charging information through gantries to a management server for fee collection, enabling payment without visiting a separate agency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate charging facilities are visited for charging and payment, then charging can be performed, but driver convenience deteriorates and time is lost
Solution Approach 1:
The patent merges the toll fee collection system and the wireless charging fee collection system into a single integrated payment platform. The fee collection server consolidates both fee types, allowing drivers to pay for both tolls and charging services through one unified interface, eliminating the need to visit separate facilities and improving driver convenience while saving time.
Solution Approach 2:
The fee collection server is designed with multi-functionality to handle both toll fee collection and wireless charging fee collection. This universal system can process different types of fees through the same payment channel, making the system adaptable to multiple service types and eliminating the need for separate payment systems.
2Productivity
If wireless charging is performed while driving on highways, then charging efficiency improves, but fee collection complexity increases
Solution Approach 1:
The patent combines the toll fee collection infrastructure with the wireless charging fee collection system. By utilizing the existing gantry-based toll collection system and integrating the charging fee calculation into the same platform, the system maintains simplicity while enabling efficient wireless charging during highway travel.
Solution Approach 2:
The fee collection server acts as an intermediary that coordinates between the wireless charging system and the toll fee collection system. It receives charging amount information from the wireless charging system, calculates the corresponding fees, and processes payment through the integrated platform, simplifying the overall fee collection process.
3Measurement precision
If charging fee is collected separately from toll fee, then fee accuracy improves, but payment process complexity increases
Solution Approach 1:
The patent merges the fee calculation and collection processes for both tolls and charging into a single unified system. The fee collection server handles both fee types simultaneously, maintaining accurate calculation for each while processing them through one payment transaction, thereby reducing payment process complexity without sacrificing fee accuracy.
