1Productivity
If phase calibration is performed in a shared wireless environment, then wireless energy transmission can be established, but interference from other non-associated sending devices causes suboptimal energy transmission efficiency
Solution Approach 1:
The system performs preliminary detection of wireless energy transmission intensity changes before completing phase calibration. By detecting abnormality in advance during the calibration process, the system can identify interference conditions early and switch to asynchronous operations, preventing suboptimal calibration results and improving overall energy transmission efficiency.
2Reliability
If asynchronous operations are enabled among multiple sending devices, then interference is mitigated and energy transmission stability improves, but device coordination complexity increases
Solution Approach 1:
The system implements a feedback mechanism where the receiving device monitors wireless energy transmission intensity changes and sends detection results back to sending devices. This feedback loop enables automatic identification of interference conditions and triggers asynchronous operation mode, achieving reliable energy transmission stability through automated coordination rather than complex manual device management.
