Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging systems for electric automobiles are cumbersome and inefficient, requiring users to manually open and close the charging base cover door and adjust the charging output, which can lead to power failures due to excessive charging capacity and incompatibility with existing home and street infrastructure.
Innovation Solution
A charging device with a charging pile and gun head connected by a transmission cable, featuring a pressing detection module, control module, wireless communication module, and output adjustment module, allowing for automatic control of the charging base cover door and output adjustment based on user input, eliminating the need for manual operation and ensuring safe and efficient charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the charging pile outputs according to maximum power, then the charging efficiency is improved, but the residence experiences overall trip and power failure
Solution Approach 1:
The charging pile dynamically adjusts its output power based on real-time detection of the residence's power supply capacity. The system transitions from a static maximum power output mode to a dynamic adaptive mode, where the charging power varies according to the detected power supply conditions, thereby preventing power failures while maintaining optimal charging efficiency.
Solution Approach 2:
The system changes the operating parameters of the charging pile by detecting power supply characteristics and adjusting the output power accordingly. This parameter adjustment allows the charging pile to operate at maximum efficiency when power supply capacity is sufficient, while automatically reducing power output when the residence's power supply capacity is limited, thus avoiding power failures.
2Reliability
If manual operations are required at both vehicle end and pile end, then the charging control is precise, but the operation becomes cumbersome and user experience deteriorates
Solution Approach 1:
The charging system performs self-service by automatically detecting power supply conditions and adjusting charging parameters without requiring manual intervention. The charging pile autonomously completes the charging process management, including power output adjustment and charging control, thereby eliminating cumbersome manual operations while maintaining precise charging control.
Solution Approach 2:
The system implements automatic feedback control where the charging pile continuously monitors power supply conditions and charging status, then automatically adjusts its output accordingly. This closed-loop feedback mechanism replaces manual operations with automated control, improving user experience while maintaining charging precision through real-time monitoring and adjustment.
3Device complexity
If the charging base cover door requires manual opening and closing, then the mechanical control is simple, but the charging process efficiency is reduced
Solution Approach 1:
The system replaces manual mechanical operation of the charging base cover door with automated control. The charging pile automatically triggers the opening and closing of the cover door through electrical or electronic control mechanisms, eliminating the need for manual mechanical operation while significantly improving charging process efficiency.

AI summary
A charging device comprises a charging pile and a charging pile gun head connected via a transmission cable, wherein the charging pile gun head is provided with a pressing detection module, and the charging pile is provided with a control module connected to the charging pile gun head, and a wireless communication module and an output adjustment module connected to the control module. In operation, the charging device receives a pressing operation of a user, correspondingly outputs a charging instruction to the electric automobile to control the opening and closing of a charging base cover door, and adjusts the charging state when the charging pile gun head is connected to the charging base of the electric automobile. The process does not require the user to manually open or close the charging base cover door, and the user can adjust the output of the charging pile via the charging pile gun head.
