Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single charging system is used, then the device complexity is reduced, but the adaptability to different electric vehicles deteriorates
Solution Approach 1:
The charging system is divided into multiple independent power modules (first power module, second power module, etc.), each capable of providing different voltage levels. These modules are connected through a distributing switch module that can selectively connect different modules to different charging ports based on the requirements of electric vehicles, thereby achieving both system simplicity and high adaptability.
Solution Approach 2:
The charging system is designed with multiple power modules that can serve multiple functions - each module can charge different types of electric vehicles with different voltage requirements. The distributing switch module enables a single charging station to universally serve various electric vehicle models simultaneously through dynamic power allocation.
2Productivity
If the output power of the charging system is increased to meet high-power charging requirements, then the charging speed is improved, but the power module utilization deteriorates
Solution Approach 1:
The distributing switch module dynamically allocates power from different modules to different charging ports based on real-time charging requirements. When high-power charging is needed, multiple modules can be connected in parallel to provide high output power for fast charging. When lower power is sufficient, the system automatically connects only the necessary modules, avoiding power waste and improving utilization efficiency.
Solution Approach 2:
The system can change the output power parameters by selectively activating different power modules. The distributing switch module adjusts the connection configuration to match the power requirements of each electric vehicle, enabling the charging system to operate at optimal power levels rather than always running at maximum capacity, thus improving both charging speed and energy efficiency.
3Adaptability or versatility
If multiple power modules are used to meet different voltage requirements, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The distributing switch module acts as an intermediary between the multiple power modules and the charging ports. It manages the complexity of connecting different voltage modules to different vehicles by providing a centralized control mechanism that automatically or manually configures the appropriate connections, thereby enabling voltage adaptability without proportionally increasing operational complexity.
4Speed
If the output power is set high for fast charging capability, then the charging speed is improved, but the power module utilization deteriorates
Solution Approach 1:
The system dynamically adjusts power module connections based on actual charging needs. When fast charging is required, multiple modules are connected in parallel to provide high power output. When standard charging suffices, fewer modules are activated, optimizing utilization and preventing energy waste while maintaining the capability for high-speed charging when needed.

AI summary
A charging system may include a plurality of power modules, a distributing switch module, and a plurality of charging ports. The distributing switch module includes a first distributing unit and a second distributing unit. The first distributing unit may connect a first part of power modules in the plurality of power modules to a first charging port, to distribute powers of the first part of power modules to the first charging port. The second distributing unit may connect a second part of power modules in the plurality of power modules to a second charging port, to distribute powers of the second part of power modules to the second charging port. Therefore, the first charging port may charge a first terminal, and the second charging port may charge a second terminal.
