EV Charging Station Service Info Transfer for Fault Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging operations for electric vehicles often fail to provide convenient access to service information for operators, leading to inconvenience for users who must physically locate and contact charging station operators for fault resolution.
Innovation Solution
A method for transmitting service information, including contact details and fault reports, directly from the charging station to the electric vehicle via the charging cable or alternative communication methods like radio, allowing users to easily contact operators through the vehicle's interface or mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If service information is displayed on a sticker at the charging station, then the information is available to users, but users must physically go to the charging station to access it which is inconvenient
Solution Approach 1:
The patent uses the charging cable as an intermediary communication channel to transfer service information from the charging station to the user's mobile device. This mediator enables information delivery without requiring the user to physically approach the charging station, thus maintaining information availability while dramatically improving user convenience.
Solution Approach 2:
The patent replaces the mechanical/physical system of displaying information on stickers at the charging station with an electronic communication system. Service information is transmitted digitally through the charging cable using communication protocols, substituting the physical information display mechanism with an electronic data transmission approach that eliminates the need for users to visit the charging station.
2Loss of information
If service information is provided via a website, then comprehensive information is available, but users must know the web address which is often not the case
Solution Approach 1:
The system enables self-service by automatically transmitting service information to users without requiring them to actively search for or navigate to a website. The charging station initiates the information delivery process, and users passively receive the information on their mobile devices, eliminating the need for users to know web addresses or perform information retrieval actions.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the charging station to automatically send service information to users during the charging process. This preliminary transmission of information occurs before users would need to access it, ensuring that comprehensive service information is already available on the user's device when needed, without requiring any prior knowledge of web addresses.
3Ease of operation
If service information is transmitted via charging cable, then information is delivered directly to the vehicle, but the charging cable must support data communication capabilities
Solution Approach 1:
The patent leverages the multi-functionality of the charging cable, which serves both as a power transmission medium and as a data communication channel. By making the cable universal for both functions, the system achieves convenient direct information delivery to the vehicle without requiring separate communication infrastructure, while maintaining compatibility with existing charging standards that already define data communication capabilities.
