Engineering Contradiction Analysis
1Power
If DC-to-DC conversion unit is used for high-power charging, then charging power is increased, but energy loss increases and heat generation increases
Solution Approach 1:
The system dynamically switches between DC-to-DC conversion unit and charge pump unit based on real-time power supply capability detection. When programmable power supply is available, it activates the charge pump unit for efficient high-power charging; when fixed power data objects are available, it uses the DC-to-DC conversion unit, optimizing energy utilization dynamically.
Solution Approach 2:
The system changes the operating parameters by selecting different charging paths based on power supply capability. It detects whether the power supply device supports programmable power supply or only fixed power data objects, and accordingly adjusts the charging mode to maintain high efficiency across different power levels.
2Power
If DC-to-DC conversion unit is used for high-power charging, then charging power is increased, but heat generation increases causing safety hazards
Solution Approach 1:
The system dynamically selects the charging path based on detected power supply capability. By activating the charge pump unit when programmable power supply is available, it achieves high-power charging with reduced heat generation compared to DC-to-DC conversion, thereby dynamically managing thermal safety.
Solution Approach 2:
The control device acts as an intermediary that detects power supply capability and routes power through the appropriate path. It mediates between the power supply device and charging components, selecting the charge pump unit as the intermediary path when programmable power supply is available to reduce heat generation.
3Loss of time
If charge pump unit is used for high-power fast charging, then charging time is reduced, but compatibility with fixed power data objects decreases
Solution Approach 1:
The system dynamically adapts its charging path based on detected power supply capability. It switches between charge pump unit and DC-to-DC conversion unit depending on whether programmable power supply or fixed power data objects are available, achieving both fast charging when possible and broad compatibility when necessary.
Solution Approach 2:
The system achieves multi-functionality by supporting both charge pump-based fast charging and DC-to-DC conversion-based charging. This universal approach allows it to work with various power supply devices regardless of whether they support programmable power supply or only fixed power data objects.
4Productivity
If high-power charging is applied to battery module, then charging speed is increased, but charging efficiency decreases due to energy loss
Solution Approach 1:
The system dynamically optimizes charging efficiency by detecting power supply capability and selecting the appropriate charging path. When programmable power supply is available, it uses the charge pump unit which maintains higher efficiency at high power levels; when fixed power data objects are available, it uses DC-to-DC conversion, dynamically adapting to maintain optimal efficiency.
Solution Approach 2:
The system changes operational parameters by selecting different charging modes based on power supply capability. It adjusts the charging path parameter to match the available power supply type, thereby optimizing the balance between charging speed and efficiency for each specific scenario.
