EV Charging Gun Selection Without QR Code Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric vehicle charging methods, which rely on scanning QR codes, are inefficient at night or in strong light conditions and can fail if the code is damaged or stained, limiting user experience and accessibility.
Innovation Solution
A method and system that determines a target charging user based on positioning information, transmitting a list of available charging guns to the user's terminal device, allowing selection without the need for code scanning, thereby enabling charging under various conditions and lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QR code scanning method is used for charging, then the charging process can be initiated, but the scanning efficiency is substantially reduced at night or under strong light conditions and may fail if the code is damaged or stained
Solution Approach 1:
The patent extracts the identification function from the QR code and relocates it to the charging gun itself. The charging gun is equipped with identification information that can be directly recognized by the charging pile, eliminating the need for user scanning operations. This resolves the contradiction by removing the fragile QR code scanning step while maintaining reliable charging initiation.
Solution Approach 2:
The patent introduces an intermediary identification mechanism between the user and the charging system. Instead of directly scanning the QR code on the charging pile, the system uses the charging gun's identification information as an intermediary that the charging pile can automatically recognize. This intermediary approach eliminates lighting dependency and code damage issues.
2Productivity
If QR code scanning is required, then charging can be started, but the process fails under various lighting conditions and requires user manual operation
Solution Approach 1:
The patent implements self-service by enabling the charging gun to automatically provide its identification information to the charging pile without requiring user scanning operations. The system autonomously completes the identification and charging initiation process, improving productivity while adapting to all lighting conditions since no visual scanning is involved.
Solution Approach 2:
The patent replaces the optical scanning mechanism (camera-based QR code reading) with an electronic identification system. The charging gun's identification information is transmitted electronically to the charging pile, substituting the light-dependent optical system with an electronic communication system that works independently of lighting conditions.
3Ease of operation
If multiple charging guns are available, then user choice is provided, but the user must manually scan and identify each code which reduces efficiency
Solution Approach 1:
The patent implements feedback by having the charging pile actively query and display identification information for multiple charging guns. The system provides real-time feedback to the user about available charging guns and their status, allowing the user to quickly select a gun without manually scanning codes. This reduces selection time while maintaining ease of operation through clear information presentation.

AI summary
A method and system for charging an electric vehicle, and a storage medium are provided. The method includes: acquiring a target charging user in a charging station and to-be-confirmed charging guns in the charging station, the target charging user being a user requires charging of the electric vehicle in the charging station, and the to-be-confirmed charging gun being a charging gun which is inserted into an electric vehicle but is not started for charging; transmitting, to a terminal device of the target charging user, a charging gun list including information about the to-be-confirmed charging guns in the charging station; receiving, from the terminal device of the target charging user, a target charging gun selected by the target charging user from the charging gun list; and controlling the target charging gun to charge the electric vehicle. The solution is applicable for charging an electric vehicle under various conditions and lights.
