Quick Meter Connect Device for EV Charging Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of electric vehicle chargers in homes and businesses is costly and time-consuming, requiring extensive rewiring and custom installations, and often leaves behind unnecessary infrastructure when the vehicle is replaced.
Innovation Solution
A Quick Meter Connect (QMC) device that easily interfaces between a utility meter and electrical service panel, providing a standardized and simple installation method for electric vehicle charging, using a cylindrical housing with connectors and a breaker switch, allowing for quick connection and disconnection without rewiring, and supporting various voltage phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a custom electric vehicle charger installation is performed with rewiring and panel modifications, then reliable power connection is achieved, but installation cost and time increase significantly
Solution Approach 1:
The device segments the charging system into a portable external unit and a simple interface adapter, eliminating the need for integrated wall-mounted installation while maintaining reliable power connection through standardized electrical interfaces
Solution Approach 2:
The interface device acts as an intermediary between the existing electrical panel and the portable charger, providing a standardized connection point that simplifies installation while ensuring reliable power transfer without requiring panel modifications
2Reliability
If extensive rewiring and panel modifications are performed, then permanent charging infrastructure is established, but removal and relocation becomes costly and complex
Solution Approach 1:
The system separates the charging infrastructure into a permanent interface adapter and a portable charger unit, allowing the adapter to remain installed while the charger can be easily removed and relocated without electrical work
Solution Approach 2:
The interface adapter is designed as a temporary, easily installable component that can be removed and discarded or relocated without cost, replacing the need for permanent custom electrical installations
3Reliability
If custom installation services are required for charger installation, then proper electrical connection is ensured, but installation cost increases to several thousands of dollars
Solution Approach 1:
The interface device uses universal standardized electrical connectors that work with existing panels and portable chargers, eliminating the need for custom installation services while maintaining safe electrical connections through code-compliant design

AI summary
An electrical meter quick connect device has a housing with open faces. A first face is configured with connectors to mate to a electrical service panel in a meter connection manner, and a second face is configured with connectors to mate to a meter in an electrical service panel connection manner. First and second set of lines are within the housing, connected from the first face to the second face. A breaker switch is on the housing and coupled to at least one of the first and second set of lines. A third set of lines is connected to the breaker switch and exits a side of the housing, the third set including a ground line. An electrical vehicle charging line is coupled to the third set of lines. The device can be inserted between a meter and electrical service panel to provide an electric vehicle power connection.
