Abstract

The invention discloses a charging control method, apparatus, adapter and system. The charging control method comprises the following steps: detecting a temperature value of a plurality of heating sources in the adapter, when determining that a highest temperature value in the temperature values of the plurality of heating sources reaches a preset temperature value, transmitting an instruction for detecting whether a working state of a terminal is in a standby state and detecting whether a battery capacity is greater than a preset battery capacity to a mobile terminal, and correspondingly adjusting a charging current outputted by the adapter according to a detection result returned by the mobile terminal, and a correspondence table of the preset temperature range and the preset charging current. By virtue of the embodiment of the invention, not only can the heat of the adapter be reduced, but also the rapidness in charging can be realized, and 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...
