Embodiment Construction

[0019] In order to facilitate the description of the charging method provided by the embodiment of the present invention, first, a brief introduction to the battery charging specification 1.2 (battery charging specification 1.2, BC1.2).

[0020] BC1.2 specifies three types of USB ports, which are standard downstream port (SDP), dedicated charging port (DCP) and charging downstream port (CDP).

[0021] 1. The D+ and D- lines of the SDP type port have 15kΩ pull-down resistors. The SDP type interface adopts the specification definition of USB2.0 or USB3.0. When the interface adopts the specification definition of USB2.0, the charging current is 500mA; the interface adopts USB2. 0 specification definition charging current is 900mA.

[0022] 2. The DCP type port provides a current above 1.5A and does not support data transmission. When charging, the D+ and D- lines in the DCP type port are short-circuited. This type of port can support higher charging capacity wall chargers and ca...

Abstract

The embodiment of the invention provides a charging method and a terminal. By the charging method and the terminal, the problem of charging time delay of the terminal is solved. The method comprises the steps of acquiring a detection result of a type of a charging interface of a charging device, wherein the detection result is a result of a type of the charging interface detected for N times by employing a first detection signal, and the charging device is connected with the terminal; detecting the type of the charging interface by employing a second detection signal if the detection result isa first result, wherein the first result is used for indicating that the type of the charging interface detected for N times is a non-special charging interface DCP, the first detection signal is a detection signal generated by a power module of the terminal, and the second detection signal is a detection signal generated by a control module of the terminal; employing the first detection signal to detect the type of the charging interface again if the type of the charging interface detected by employing the second detection signal is the DCP; and employing a first power corresponding to the DCP to charge the terminal if the type of the charging interface detected by employing the first detection signal again is the DCP.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of terminals, and in particular, to a charging method and a terminal. Background technique [0002] With the development of terminal technology, since users are more and more dependent on the terminal, when the power of the terminal is exhausted, the user has higher and higher requirements on the charging time of the terminal. [0003] Generally, the terminal can establish a charging system through a universal serial bus (universal serial bus, USB) and an adapter. At present, the terminal determines whether the charging system can fast charge by detecting whether the charging port of the adapter is a dedicated charging port (dedicated charging port, DCP). If it detects that the charging interface is DCP, the terminal determines that the adapter can be charged quickly (for example, it can be charged with a charging signal of 5V / 1.5A); if it detects that the charging interface is not DCP...
