Embodiment 1

[0061] Embodiment one, see image 3 Detailed description, image 3 It is a schematic flow chart of this embodiment.

[0062] Step 501: output the current stored in the battery, and output the current after being regulated by its own newly added current management module.

[0063] The adjustment of the output current itself may include adjusting the magnitude of the current to ensure that the output current can meet the current demand for terminal charging, or control the current by setting the charging duration and the lower limit of the charging power through software.

[0064] The current is usually stored in the battery, and the output current can use the USB female port or the newly added male port. The newly added male ports can include USB male ports and power male ports.

[0065] The male port and the female port are matching connection interfaces. Usually, the female port is a recessed interface, and the male port is a protruding interface. The female port and the m...

Embodiment 2

[0072] Embodiment 2. The embodiment of the present invention will be described in detail by taking mobile phone A as the current output terminal and terminal B as the current input terminal as an example. Terminal B can be a mobile phone, a wireless fixed-line terminal, a digital photo frame, a digital camera, an MP3 player, etc.

[0073] Step 601: mobile phone A detects that terminal B is connected to itself.

[0074] The PMU module can detect the connection of the power port, the USB controller module can detect the connection of the USB port, and the software control program can detect that the terminal B has been connected to itself by detecting the PMU module and the USB controller module.

[0075] Step 602: Prompt the user whether to start external charging, if yes, go to step 603, otherwise go to step 612.

[0076] Step 603: The PMU module controls battery discharge.

[0077] After the user confirms the start of external charging through the software control program, t...

Abstract

The embodiment of the invention discloses a terminal and a method used for external charging; wherein, the terminal comprises a battery which is used for storing current, a current management module which is used for regulating the current output from the battery and distributing the current to a current output module, the current output module which is used for outputting the current distributed by the current management module, and a charging module which is used for external charging by the current output by the current output module; the charging method comprises the steps as follows: the current stored in the battery is output after being regulated by the newly self-added current management module; and the output current charges the other terminal. The embodiment of the invention requires no other charging facilities, the direct output terminal carries out external charging by the self-stored regulated current; furthermore, the self-USB receptacle of the terminal and the newly added plug can be utilized so that the terminals can charge each other, and can be used more conveniently and smartly.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal and method for external charging. Background technique [0002] At present, the method of charging the battery of the terminal, that is, inputting current to the battery, generally includes: using a charger matched with the terminal to connect to an AC power socket for charging; using a universal serial bus (Universal Serial Bus, USB) to connect to a computer for charging. [0003] During the research and practice of the prior art, the inventors of the present invention have found that the prior art has the following problems: [0004] Charging cannot be performed without other charging peripherals, such as chargers, power sockets, USB cables, etc. Therefore, it is difficult to charge the terminal outdoors or without these charging peripherals. Contents of the invention [0005] The technical problem to be solved by the embodiments of the present inve...
