Abstract

A charging method and system, a charging box and Bluetooth earphones are disclosed. The charging method is applied to the charging box, and comprises: acquiring a communication data packet of Bluetooth earphones according to a preset communication frequency when the charging box is charging the Bluetooth earphones, wherein the communication data packet includes a current battery voltage of the Bluetooth earphones (S 10 ); determining a target charging voltage according to the current battery voltage (S 20 ); and charging the Bluetooth earphones based on the target charging voltage (S 30 ). The charging method can realize the dynamic adjustment of the charging voltage, reduce the energy loss of the charging box during the charging process, thereby increasing the number of times that the charging box can charge the Bluetooth earphones and improving the battery life of the Bluetooth earphones.
