EV Charging Station Data Relay for Faster Charging and Media Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging devices for electric vehicles often require longer charging times due to limited network data transfer speeds, especially in remote areas, which also hinder the efficient use of user terminals for video and audio playback, reducing charging convenience.
Innovation Solution
A charging device with integrated receiving and communication units that establish a high-speed data connection with playback units, enabling simultaneous power transfer and data transmission, including video and audio streaming, even in areas with low network speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a charging cable is used to transmit both power and data to user terminals, then data transmission is enabled, but charging speed is reduced and charging time is increased
Solution Approach 1:
The patent segments the transmission functions by separating data transmission from power transmission. A wireless communication unit handles data transmission to user terminals, while the charging cable is dedicated solely to power transmission, eliminating the trade-off between data transmission capability and charging speed.
2Loss of information
If network connection is used for data transmission in remote areas, then data communication is enabled, but data transfer speed is low
Solution Approach 1:
The charging device acts as an intermediary with a local server that caches content locally. User terminals can quickly access content from this local server without relying on slow remote network connections, thereby enabling fast data transfer even in remote areas with poor network infrastructure.
3Adaptability or versatility
If charging devices are provided along routes for long-distance travel, then operating range is extended, but network availability is limited
Solution Approach 1:
The system performs preliminary actions by caching video and audio content in advance on a local server at the charging device. This allows user terminals to access pre-cached content quickly during charging, eliminating the need for real-time network connectivity and making the system adaptable to remote locations with limited network availability.
