1Productivity
If multiple output ports are provided for simultaneous charging of multiple devices, then charging capacity is improved, but device complexity increases making it difficult for users to identify correct fast charging interfaces
Solution Approach 1:
The charging system automatically detects which output ports are connected to external devices and intelligently allocates transformer modules without user intervention. The controller identifies connected ports through detection circuits and autonomously configures power distribution, eliminating the need for users to manually select or identify specific fast charging ports.
Solution Approach 2:
The system dynamically adjusts the connection relationships between transformer modules and output ports based on real-time detection results. When external devices are connected, the controller reconfigures which transformer modules supply power to which ports, allowing flexible adaptation to different charging scenarios and maintaining optimal power distribution.
2Productivity
If each output port is assigned to a specific transformer module for fast charging, then charging efficiency is improved, but device complexity increases requiring instructions or labels for port selection
Solution Approach 1:
The system performs automatic port detection and transformer module allocation without requiring user knowledge or manual selection. The detection circuit automatically identifies which ports have external devices connected, and the controller autonomously assigns appropriate transformer modules to these ports, enabling fast charging to occur automatically at the correct ports without user intervention or reference to instructions.
Solution Approach 2:
The system uses detection circuits to continuously monitor the connection status of each output port and provides feedback to the controller. Based on this real-time feedback, the controller dynamically adjusts which transformer modules are connected to which ports, ensuring that fast charging is activated at the appropriate ports while maintaining ease of operation.
3Productivity
If transformer modules are increased to support fast charging at all output ports simultaneously, then charging capacity is improved, but device complexity and cost increase
Solution Approach 1:
The system dynamically reconfigures the connection between transformer modules and output ports based on detection results. A single transformer module can be dynamically connected to different output ports as needed, allowing the system to support fast charging at multiple ports sequentially or simultaneously without requiring a dedicated transformer module for each port, thereby reducing overall complexity.
Solution Approach 2:
Each transformer module is designed to be multi-functional, capable of supplying power to any output port through dynamic reconfiguration. This universal design allows fewer transformer modules to serve multiple purposes and support charging at multiple ports, reducing the total number of transformer modules needed while maintaining high charging capacity.
