Home EV Charging Authentication for Company Vehicle Reimbursement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately monitor and reimburse employees for charging professional electric vehicles at home, as they lack the ability to identify the vehicle type and associate electricity consumption with company expenses, and there is no clear method for ensuring the vehicle is professional rather than private.
Innovation Solution
A method involving a home charging terminal that authenticates the vehicle before charging, using authentication data such as codes or unique identification keys, and a charging management server to manage and track electricity consumption for reimbursement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If employees charge professional electric vehicles at home using household sockets or basic heavy-duty sockets, then charging accessibility is improved, but charging speed deteriorates and installation complexity increases
Solution Approach 1:
The patent segments the charging infrastructure into multiple levels: household sockets for basic accessibility, heavy-duty sockets for improved speed, and Wallbox terminals for optimal performance. This segmentation allows employees to choose appropriate charging solutions based on their specific needs and installation constraints.
Solution Approach 2:
The patent introduces dynamic elements through Wallbox terminals that can adapt charging parameters, provide real-time monitoring, and communicate with company systems. This dynamic capability allows the system to optimize charging speed and manage power consumption based on grid conditions and vehicle requirements.
2Ease of operation
If employees charge professional electric vehicles at home, then charging convenience is improved, but cost monitoring and reimbursement accuracy deteriorate
Solution Approach 1:
The patent implements feedback mechanisms through Wallbox terminals that continuously monitor charging parameters, track electricity consumption, and communicate this data to company systems. This feedback loop enables accurate measurement of professional vehicle charging costs and facilitates automated reimbursement processes.
Solution Approach 2:
The patent introduces an intermediary charging management system that acts as a mediator between the employee's home charging setup and the company's reimbursement system. This intermediary collects authentication data, monitors consumption in real-time, and provides verified data for accurate reimbursement, solving the measurement precision problem.
3Measurement precision
If authentication systems are implemented at home charging terminals, then vehicle identification accuracy is improved, but system complexity and installation cost increase
Solution Approach 1:
The patent makes the Wallbox terminal a universal device that combines multiple functions: charging delivery, authentication verification, consumption monitoring, and data communication. By integrating these functions into a single terminal, the system achieves high vehicle identification accuracy without proportionally increasing overall system complexity.
Data Source
AI summary
The management of the charging of an electric vehicle, via a charging terminal. A method for managing this charging includes: connecting a charging cable between the electric vehicle and the charging terminal; the charging terminal receiving authentication data in relation to the electric vehicle; the charging terminal triggering the charging at the end of an inspection on the authentication data when the authentication data concern a second user, different from the first user and authorized to carry out charging.
