Abstract

The invention discloses a charging control method and device, an adapter and a charging control system. The charging control method comprises the following steps: sampling the temperature value of the heat source in the adapter to obtain the temperature variation state of the adapter during the preset time period; judging whether the adapter is abnormal or not according to the temperature variation state; if so, disconnecting the passageway of the adapter and the alternating current; if not, sending the instructions of detecting the operation state of the mobile terminal and the electric quantity of the battery, so as to adjust the charging current outputted by the adapter according to the adjusting strategy corresponding to the detection results returned by the mobile terminal. According to the embodiment of the invention, the heating of the adapter can be reduced, and the fast charging can be realized, therefore, the charging temperature of the adapter can be controlled in a reasonable range while the hardware performance of the adapter is protected.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to the field of mobile terminals, and in particular to a charging control method, device, adapter and system. Background technique [0002] With the development of terminal technology, users can not only use mobile terminals for traditional applications, such as using mobile phones to answer or make calls, but also use mobile terminals for video playback, audio playback, web browsing, taking pictures, navigation, and playing games, etc. application. [0003] With the increase in the frequency of use of mobile terminals, mobile terminals need to be charged frequently to meet the needs of users. The fast charging technology that uses adapters and mobile terminals for high-current charging is also widely used to meet the needs of batteries as full as possible in a short period of time. However, due to the problem of power conversion efficiency, charging with a large cur...
