EV Home Charging Billing Control for Shared Parking Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There are challenges in promoting the installation of electric vehicle charging stations and rationalizing electricity rates, particularly in managing electric rete payments and providing flexible charging solutions.
Innovation Solution
An electric vehicle charging system that includes a building with a power consumption unit, a parking space, a charging apparatus, an electric power supply unit, and an electric power lending/borrowing system. This system controls electric rate liquidation by billing the power supply unit for the power used minus the power charged to an electric vehicle, and bills the electric vehicle owner for their charging costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If charging stations are deployed at facilities like car dealerships, convenience stores, and parking lots, then charging infrastructure coverage is improved, but electricity rate rationalization and payment management become more complex
Solution Approach 1:
The patent introduces a charging management system as an intermediary between power supply units and charging apparatus. This system handles the complex electricity rate liquidation and payment management automatically, separating the complexity from the physical charging infrastructure deployment. The management system processes power consumption data, calculates charges based on different rate structures, and manages settlements between stakeholders.
2Ease of operation
If charging systems are installed in home garages to promote installation, then accessibility is improved, but electricity rate liquidation between multiple parties becomes more difficult
Solution Approach 1:
The patent implements a feedback mechanism where the charging management system continuously monitors power consumption data from charging apparatus, communicates with power supply units to obtain rate information, and automatically performs electricity rate liquidation. The system provides real-time feedback on charging status, power consumption, and settlement information to all stakeholders, enabling transparent and automated rate management for home garage charging.
3Adaptability or versatility
If electricity rates are kept low to respond to urgent charging needs, then user flexibility is improved, but revenue recovery for power supply units becomes problematic
Solution Approach 1:
The patent implements dynamic electricity rate structures that can adjust pricing based on time, location, and power supply conditions. The charging management system enables flexible rate setting where different rates apply to different charging scenarios (e.g., peak/off-peak hours, different locations, different power sources). This dynamic pricing mechanism allows low rates during off-peak periods to maintain user flexibility while ensuring adequate revenue recovery through higher rates during peak periods or specific conditions.
Data Source
AI summary
A household has a parking space with charging apparatus for an electric vehicle connected to a home use commercial power source. The parking space allows another person's electric vehicle to charge it. Identification of such electric vehicle on its license plate or the like and amount of charging it are reported to an electric power lending/borrowing system which controls electric rate liquidation so that the household is billed for the total electric power minus the power charging the electric vehicle, and that the power charging the electric vehicle is billed to an owner of the electric vehicle. The electric power lending/borrowing system discloses the location of reachable households in the system on the map of car navigation system of electric vehicles also in the system.
