Charging Power Control for Bluetooth Interference During Fast Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging processes in electronic devices can interfere with Bluetooth communication, leading to abnormal states and user experience issues due to high voltage requirements, which affect other circuits and disrupt media file playback.
Innovation Solution
A charging control method that monitors the Bluetooth communication state during charging and adjusts the charging power based on supported protocols to reduce interference, by determining if the current protocol can adjust the charging power to a lower threshold and switching to a protocol that supports the necessary voltage or current levels to maintain normal communication.

Engineering Contradiction Analysis
1Productivity
If high charging power is used to ensure fast charging, then charging speed is improved, but Bluetooth communication stability deteriorates due to voltage interference with other circuits
Solution Approach 1:
The charging power is made dynamically adjustable based on real-time monitoring of Bluetooth communication status. The system switches between different charging power levels (first charging power for normal communication, second charging power lower than first for abnormal communication) to maintain both fast charging capability and communication stability
Solution Approach 2:
The system changes the charging voltage parameter dynamically. When Bluetooth communication becomes abnormal during charging, the charging voltage is adjusted from a first voltage to a second voltage (lower than the first), which resolves the interference issue while maintaining charging functionality
2Power
If charging voltage is increased to support high-power charging protocol, then charging power capability is improved, but interference with other circuit operations increases
Solution Approach 1:
The system performs preliminary monitoring of Bluetooth communication status during the charging process. By detecting communication abnormalities early, the system can proactively adjust the charging voltage before the interference causes complete communication failure or device malfunction
Solution Approach 2:
The system implements a feedback mechanism where Bluetooth communication status is continuously monitored during charging. Based on this feedback, the charging voltage is automatically adjusted - maintaining high voltage when communication is normal, and reducing voltage when communication becomes abnormal, thus resolving the contradiction between power capability and circuit interference

AI summary
The present disclosure relates to a charging control method and a charging control apparatus, an electronic device and a storage medium. The method is applicable for a first terminal and includes: monitoring (S101) a Bluetooth communication state between the first terminal and the second terminal in a process of charging the first terminal; when (S102) the Bluetooth communication state is monitored to be in an abnormal state, adjusting the charging power for charging the first terminal based on the charge protocol supported by the first terminal. Based on the charging control method, it is determined whether a progress of charging the first terminal affect the Bluetooth communication between the first terminal and the second terminal by monitoring the Bluetooth communication state between the first terminal and the second terminal, so that the charging power may be adjusted timely, and normal Bluetooth communication may be guaranteed.
