1Stability of the object's composition
If fixed charging current is used for each charging integrated circuit, then the charging current is stable and simple to control, but the temperature distribution across working components becomes uneven, affecting user experience
Solution Approach 1:
The patent implements dynamic charging current regulation by making the charging current adjustable based on real-time temperature feedback. The system transitions from fixed current to variable current that adapts to different working scenarios, allowing optimization of temperature distribution while maintaining charging functionality.
Solution Approach 2:
The patent employs temperature feedback mechanisms where temperature values of working components are continuously monitored and fed back to the control system. This feedback is used to dynamically adjust the charging current of different charging integrated circuits, creating a closed-loop control system that balances temperature distribution.
2Temperature
If charging current of each charging integrated circuit is dynamically adjusted, then temperature distribution uniformity is improved, but the control complexity increases
Solution Approach 1:
The patent divides the charging system into multiple independent charging channels, each with its own charging integrated circuit that can be individually controlled. This segmentation allows separate regulation of each channel's current based on local temperature conditions, simplifying the overall control strategy by breaking down the complex multi-variable problem into manageable independent control loops.
Solution Approach 2:
The patent applies different charging current values to different charging integrated circuits based on their local temperature conditions and proximity to specific working components. Each charging channel receives customized current regulation tailored to its local thermal environment, optimizing temperature distribution without requiring complex global control algorithms.
3Temperature
If charging current is reduced to lower temperature, then temperature rise is controlled, but charging speed decreases
Solution Approach 1:
The patent applies differentiated current regulation to different charging channels, allowing some channels to maintain higher current for fast charging while others reduce current for temperature control. This localized quality approach ensures that charging speed is maintained in regions where temperature is acceptable, while temperature is controlled in regions where it is critical.
Solution Approach 2:
The patent dynamically adjusts charging current based on real-time temperature conditions, allowing the system to switch between different charging modes as needed. When temperature is within acceptable ranges, higher current is applied for fast charging; when temperature rises, current is reduced for thermal management, creating a dynamic balance between charging speed and temperature control.
