A charging control method that monitors the Bluetooth communication state in real-time and adjusts the charging power based on supported charge protocols to minimize interference between the charging circuit and Bluetooth communication interface, ensuring normal communication and media playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high voltage charging protocol is used to ensure fast charging, then charging power is improved, but Bluetooth communication interference increases
Solution Approach 1:
The patent implements dynamic adjustment of charging power based on real-time detection of Bluetooth communication status. The system switches between different charging protocols (first protocol with higher power, second protocol with lower power) depending on whether communication interference is detected, making the charging power dynamic rather than fixed.
Solution Approach 2:
The system establishes a feedback loop where Bluetooth communication quality is continuously monitored during charging. Based on this feedback, the charging controller adjusts the charging power accordingly - reducing power when interference is detected and restoring higher power when communication is normal, creating a closed-loop control system.
2Reliability
If charging power is reduced to eliminate Bluetooth interference, then communication stability is improved, but charging speed decreases
Solution Approach 1:
The system employs periodic switching between different charging protocols based on communication needs. Instead of maintaining a fixed low power level, the system alternates between high-power charging (when communication is not required or is stable) and low-power charging (when communication is active), achieving both fast charging and stable communication through time-based periodic action.
Solution Approach 2:
The charging power is made dynamic by continuously monitoring communication status and adjusting power levels in real-time. The system transitions between different power states based on actual communication requirements, ensuring maximum charging speed is achieved whenever possible while maintaining communication stability when needed.

AI summary
The present disclosure relates to a charging control method applicable for a first terminal. The method includes: monitoring a Bluetooth communication state between the first terminal and the second terminal in a process of charging the first terminal. When the Bluetooth communication state is monitored to be in an abnormal state, the charging power for charging the first terminal is adjusted reduced based on the charge protocol supported by the first terminal.
