Embodiment Construction

[0059] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0060]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 first configures the communication mode of the direct charging power adapter, and preferably adopts the wireless communication mode to perform data interaction with the mobile terminal to be charged; According to the configuration situation, the detection mechanism is designed so that...

Abstract

The invention discloses a mobile terminal, a direct chargeable source adapter and a charging method. Firstly, the direct chargeable source adapter is configured to communicate with the mobile terminal in a wireless communication mode, and then according to the different configurations of the communication pins of different charging devices, the The 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 charging source adapter. During the concentrated charging period of the battery of the mobile terminal, the charging voltage output by the direct charging source adapter is used to directly charge the battery with a large current, and the battery is dynamically charged according to the change of the battery voltage. The volt value of the charging voltage is adjusted accurately, thus under the premise of ensuring the safety of battery charging, the charging speed of the battery is greatly improved, the time required for a single charging of the mobile terminal is shortened, and the frequent charging of the mobile terminal is reduced. , The impact of long-term charging on the daily use of users.

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...
