Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single detection loop is used for charging guns, then the device complexity is reduced, but the ability to implement multi-gun fast charging is limited
Solution Approach 1:
The detection loop is segmented into multiple independent detection circuits, with each circuit corresponding to a specific charging gun. This allows each charging gun to be detected independently, enabling multi-gun fast charging capability while maintaining manageable system complexity through modular design
2Measurement precision
If multiple detection loops are implemented for multiple charging guns, then the connection status detection accuracy is improved, but the device complexity increases
Solution Approach 1:
Multiple detection loops are designed with identical structures and functions, each capable of detecting the connection status of a charging gun. This universal design approach improves detection accuracy for each gun while avoiding the need for complex heterogeneous detection systems
3Productivity
If connection status of multiple charging guns is detected, then the charging parameter optimization is improved, but the control system complexity increases
Solution Approach 1:
The control system receives feedback signals from multiple detection loops regarding the connection status of each charging gun. Based on this feedback, the controller automatically adjusts charging parameters to optimize charging efficiency, creating a closed-loop control system that balances productivity improvement with manageable complexity

AI summary
A vehicle, a vehicle charging system, a method, and a computer-readable storage medium. The vehicle charging system includes a first detection loop configured to detect a connection status of a first charging gun, and a second detection loop configured to detect connection statuses of a plurality of second charging guns. The system further includes a first charging loop for charging a vehicle power battery through the first charging gun, and a plurality of second charging loops, each corresponding to one of the second charging guns and configured to charge the power battery accordingly. A controller determines the connection status of the first charging gun and the second charging guns, and controls the first and second charging loops based on a charging parameter associated with the detected connection status, to perform charging of the power battery. This system enables dynamic control of charging paths for vehicle charging efficiency and safety.
