Problems solved by technology

[0003] Fast charging through high current has some safety hazards
If the charging interface of the terminal device is polluted by foreign matter or the terminal device is in a relatively humid environment (such as a bathroom), the foreign matter pollution or humid environment will cause a short circuit on the charging port, and the charging current will be between the charger and the charging port. A current loop is formed. When the charging current is large, the short-circuited charging interface will generate a lot of heat. If the user does not find out in time, it will burn out the terminal equipment, and cause explosions, fires and other hazards.

Embodiment Construction

[0061] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0062] Please refer to Figure 1A , which shows a schematic diagram of charging a terminal device through a charger under normal conditions. The charging interface of the terminal device is usually a USB (Universal Serial Bus, universal serial bus) interface, and the charger is connected to the charging interface of the terminal device through the USB. In the embodiment of the present...

Abstract

The invention discloses a charging control method and device, and belongs to the technical field of mobile terminals. The method comprises the following steps: in the charging process of terminal equipment, obtaining the temperature collected by a temperature sensor in a radio frequency assembly arranged adjacent to a charging interface of the terminal equipment; and controlling the charging state of the terminal equipment according to the temperature. The damage caused by the fact that the charging interface is short-circuited when the terminal equipment is charged is avoided, the temperature is collected by the temperature sensor in the radio frequency assembly arranged adjacent to the charging interface, and one temperature sensor does not need to be independently arranged at the position of the charging interface, so that the structural complexity and cost are reduced.

Description

technical field [0001] The present disclosure relates to the technical field of mobile terminals, and in particular to a charging control method and device. Background technique [0002] With the continuous improvement of users' requirements on the charging speed of terminal equipment, fast charging through high current has become a common charging solution. [0003] Fast charging through high current has some safety hazards. If the charging interface of the terminal device is polluted by foreign matter or the terminal device is in a relatively humid environment (such as a bathroom), the foreign matter pollution or humid environment will cause a short circuit on the charging port, and the charging current will be between the charger and the charging port. A current loop is formed. When the charging current is large, the short-circuited charging interface will generate a lot of heat. If the user does not find out in time, it will burn out the terminal equipment, and cause ex...
