EV Charging Plug Display for Real-Time Charge Progress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Central charging infrastructure for electric vehicles lacks user feedback on current charging operations, reducing user comfort and awareness of charging progress.
Innovation Solution
Integration of a charge indicator directly on the charging plug of the charging cable, which displays charging progress using a display with a loading bar, circle, or percentage indicator, and optionally indicates energy transmission in kilowatt hours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central charging infrastructure with permanently connected cables is used, then maintenance costs are reduced and electrical safety is improved, but users are not informed about current charging operations
Solution Approach 1:
The patent implements a feedback mechanism by integrating a charge indicator directly on the charging plug. This indicator provides real-time visual feedback to users about charging status, charging progress, and energy transmitted, resolving the information loss issue while maintaining the safety benefits of central charging infrastructure
2Ease of operation
If charging progress information is provided through apps or remote indicators, then user comfort is improved, but device complexity and additional components are required
Solution Approach 1:
The charging plug itself serves the dual function of both charging delivery and information display. The charge indicator is integrated directly into the plug, allowing it to provide charging progress information autonomously without requiring external apps, remote indicators, or additional complex systems
Solution Approach 2:
The patent combines the charging function and information display function into a single integrated unit (the charging plug). This merging eliminates the need for separate indicator devices or software applications, reducing overall system complexity while maintaining user comfort
