Embodiment Construction

[0055] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] 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 the host, the conventional power adapter and the 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 p...

Abstract

The invention discloses a mobile terminal, a direct charging power adapter and a charging method. The method comprises the steps: the mobile terminal detects the short circuit condition of two communication pins in the USB interface of the mobile terminal, when the mobile terminal is inserted by an external equipment which is the power adapter, the mobile terminal can automatically identify the type of the external connected charging equipment by adopting the power adapter communication; at the same time, a special express charge mode is designed for the direct charging power adapter, when a battery of the mobile terminal is concentratedly charged, the battery is directly charged with heavy current by using the charging voltage outputted by the direct charging power adapter, and the volt value of the charging voltage can be dynamically adjusted according to the variation of the voltage of the battery. According to the above, on the premise that the safety of the battery charge is guaranteed, the great increase of the battery charging speed is realized, the required time of single charging of the mobile terminal is shortened, the influences on daily use of user caused by the repeatedly and long time charging of the mobile terminal is reduced, and the user satisfaction is greatly improved.

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...
