Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] In order to enable the mobile terminal with a built-in rechargeable battery to automatically and accurately identify the type of external device currently inserted, so as to call different charging management modes according to different charging characteristics of different external devices, and realize the rationalization of charging resources Utilization, the present invention proposes a charging method for three kinds of external devices, namely, a host, a conventional power adapter, and a direct charging power adapter. The method firstly configures the communication mode of the direct charging power adapter, and preferably adopts the UART (serial asynchronous transceiver) communication mode to perform data interaction with the mobile terminal to be charged; The configuration of the interface pins of the power...

Abstract

The invention discloses a mobile terminal, a directly chargeable power source adapter and a charging method. First, the direct chargeable power source adapter is configured to communicate with the mobile terminal in a UART communication mode, and then according to the different configuration of the communication pins of different charging devices, the A charging type identification strategy is designed in the mobile terminal, thereby realizing the automatic identification of the external device type by the mobile terminal. At the same time, a special fast charging mode is designed for the direct-chargeable power adapter. During the concentrated charging period of the battery of the mobile terminal, the battery is directly charged with a large current using the charging voltage output by the direct-chargeable power source adapter, and dynamically according to the change of the battery voltage. Therefore, on the premise of ensuring the safety of battery charging, the charging speed of the battery is greatly improved, the time required for a single charge of the mobile terminal is shortened, and the frequency required by the mobile terminal is reduced. , The impact of long-term charging on users' daily use.

Description

technical field [0001] The invention belongs to the technical field of DC charging, and in particular relates to a method for charging a battery inside a mobile terminal, a mobile terminal and a direct charging source adapter supporting the charging method. Background technique [0002] At present, portable mobile terminals have penetrated into every aspect of people's lives and become the leading force leading the progress of the semiconductor industry. Most of the current portable mobile terminals use rechargeable batteries to power the internal system circuits of the products. As portable products support more and more functions, the power consumption of their system circuits also increases. In the case of limited battery capacity, the battery life after charging is gradually shortened, resulting in more and more frequent charging operations. . [0003] At present, there are two main battery charging methods widely used: one is to use a conventional power adapter (charg...
