Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric automobile charging process is cumbersome and inefficient, requiring users to manually operate the charging base cover door and often necessitating frequent charging, which can be inconvenient and complex, especially without the vehicle key.
Innovation Solution
A charging control method and device that establish a communication connection between the charging pile and the electric automobile, allowing the charging pile to automatically open the vehicle charging base cover door when the charging gun head is picked up by the user, simplifying the charging process and eliminating the need for manual operation of the cover door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of charging base cover door is required, then charging process control is precise, but ease of operation deteriorates
Solution Approach 1:
The charging pile system automatically detects when a charging gun is picked up and autonomously opens the vehicle's charging base cover door through wireless communication, eliminating the need for manual operation by the user. The system serves itself by performing the cover door opening action without human intervention.
Solution Approach 2:
The patent replaces manual mechanical operation of the charging base cover door with an automated electronic control system. The charging pile uses detection modules to sense gun pickup and communicates wirelessly with the vehicle to electronically trigger cover door opening, substituting mechanical user action with an automated electromechanical system.
2Productivity
If multiple manual steps are required for charging, then charging process control is precise, but productivity deteriorates
Solution Approach 1:
The charging pile performs preliminary detection to determine whether the charging gun has been picked up before initiating the charging process. This preliminary action triggers a sequence of automated events including cover door opening and charging initiation, streamlining the overall process and improving productivity.
Solution Approach 2:
The patent implements a continuous automated workflow where detection of gun pickup continuously triggers the next steps in the charging sequence without interruption. The system maintains continuous useful action from detection through cover door opening to charging initiation, eliminating idle manual steps and improving overall productivity.
3Ease of operation
If communication connection is established between charging pile and vehicle, then ease of operation improves, but device complexity worsens
Solution Approach 1:
The charging pile incorporates a multi-functional integrated system that combines detection capabilities, wireless communication modules, and control functions into a single universal device. This allows the charging pile to perform multiple tasks including gun pickup detection, cover door opening control, and charging management, improving ease of operation while consolidating complexity into a unified system.

Data Source
AI summary
A charging control method and a charging device for an electric automobile is are disclosed. The charging device includes a charging pile and a charging pile gun head, and the method firstly establishes a communication connection between the charging pile and the electric automobile within a preset range of the charging pile, then determines whether the charging pile gun head is picked up by a user, and sends an instruction to open the vehicle charging base cover door to the electric automobile when it is determined that the charging pile gun head is picked up by the user to enable the charging pile gun head to be inserted into the charging base of the electric automobile to charge the electric automobile. The charging control method enables a user to charge the electric automobile with simple operation without manually opening or closing the charging base cover door.
