Electric Vehicle Charging Fee Collection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a convenient and secure system to calculate and collect electric charge fees for electric vehicles, as existing systems often lead to dual billing issues and lack efficient infrastructure for plug-in charging.
Innovation Solution
A system comprising a charge control unit, a power usage amount and cost calculation unit, and a collection means, which includes a plug for connecting to a power supply, a power usage measuring unit, a database for storing electricity rates, and a collection mechanism to deduct and pay for electricity usage, preventing dual billing by using a double metering blocking unit and electronic payment systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plug-in charging infrastructure is established for electric vehicles, then charging convenience is improved, but dual billing issues and measurement accuracy problems arise
Solution Approach 1:
The patent introduces a dual metering blocking unit as an intermediary device between the power supply and the charging system. This unit acts as a mediator that coordinates with both the power supply metering unit and the charging control unit to prevent dual billing by blocking redundant metering measurements while enabling convenient plug-in charging at various locations.
2Reliability
If power usage amount is measured at multiple points, then billing completeness is improved, but measurement consistency and dual billing problems occur
Solution Approach 1:
The dual metering blocking unit performs preliminary anti-action by preemptively blocking redundant metering measurements before dual billing can occur. It receives power usage amount information from the power supply and proactively prevents duplicate measurement at the charging end, ensuring billing completeness without measurement inconsistency.
Solution Approach 2:
The system implements feedback mechanisms where the dual metering blocking unit continuously receives power usage amount information from the power supply metering unit and adjusts its blocking actions accordingly. This feedback loop ensures that metering measurements remain consistent and accurate throughout the charging process.

AI summary
An electric charge fee calculation and collection system for an electric vehicle includes a charge control unit that receives power from a power supply means and charges a battery of the vehicle; a power usage amount and cost calculation unit that measures a power usage amount supplied to the battery from the power supply means and calculates an electricity rate corresponding to the measured power usage amount; and a collection means that collects the electricity rate from a user.
