[0026] see figure 1 , figure 1 is a structural diagram of a charger provided by an embodiment of the present invention, such as figure 1 As shown, the charger includes a first central processing unit 101 and a controller 102, wherein:

[0027] The first central processing unit 101 is configured to detect whether a power-off instruction sent by the mobile terminal is received, and output a first control signal to the controller 102 if the power-off instruction is detected.

[0028] The first central processing unit 101 is connected to the controller 102 . The mobile terminal will monitor the state of the battery pack in real time, and when it detects that the charging of the battery pack is complete, the mobile terminal will send a power-off command to the first central processing unit 101 of the charger, and the first central processing unit 101 of the charger receives this After the power-off command, a first control signal will be sent to the controller 102 .

Abstract

The invention provides a charging method, a charger and a mobile terminal. The charger comprises a first central processing unit and a controller; the first central processing unit is used for detecting whether an outage instruction sent by the mobile terminal is received or not and outputting a first control signal to the controller if the outrage instruction is detected; the controller is used for controlling the charger to stop outputting charging voltage according to the first control signal. After charging of the mobile terminal is completed, the outrage instruction is sent to the charger, the charger stops outputting the charging voltage after receiving the outrage instruction, a USB (universal serial bus) connector of the mobile terminal cannot be in a state of continuously being plugged into a power supply, risk of electric leakage among pins in the USB connector is lowered, accelerated corrosion oxidation of the USB connector of the mobile terminal under the charged state is prevented, and service life of the USB connector is prolonged.

Description

technical field [0001] The present invention relates to the communication field, in particular to a charging method, a charger and a mobile terminal. Background technique [0002] At present, when charging the mobile terminal, the user often forgets to pull out the power supply in time. Generally, the power of a mobile terminal can be fully charged within 3 hours, especially after using fast charging, the time to complete charging is even shorter, or even less than 100 minutes. After the charging of the mobile terminal is completed, if the power supply is not pulled out in time, the Universal Serial Bus (USB, Universal Serial Bus) connector of the mobile terminal will always be in a state of being powered but not charged in the following time. [0003] Usually, the USB connector of the mobile terminal is easy to enter ionic impurities, such as dust, fiber, metal particles or sweat and so on. When there are ionic impurities in the USB connector, the metal parts of the USB c...
