Abstract

The embodiment of the invention discloses a battery charging control method and device and a terminal. The battery charging control method comprises the steps of detecting the working state of a preset data transmission control switch; detecting whether or not the terminal conducts data transmission of a preset class if the working state of the preset data transmission control switch is detected to be a connecting state; switching the working state of the preset data transmission control switch from the connecting state to a disconnecting state if it is detected that the terminal does not conduct the data transmission of the preset class; triggering the terminal to arrange a recognition pin of a universal serial bus interface to be a universal input / output interface mode with low level output according to the disconnecting state so as to conduct battery charging on the terminal. According to the battery charging control method and device and the terminal, through the method of arranging the recognition pin of the universal serial bus interface of the terminal to be the universal input / output interface mode with the low level output, the problem that the terminal can not be charged which is caused by OTG wrong response brought by the situation that the recognition pin of the universal serial bus interface of the terminal is in short circuit with the pin of a ground electrode can be avoided.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a charging control method, device and terminal. Background technique [0002] Many terminals have OTG (On The Go) function. OTG technology can realize data exchange between devices without a host. For example, a smart phone can be directly connected to a USB flash drive (USB Flash Disk, USB flash drive) through an OTG data cable, so that the smart phone can read data stored in the USB flash drive. [0003] The terminal uses a USB (Universal Serial Bus, universal serial bus) interface to identify whether the user connects to the terminal with a common USB data cable or an OTG data cable. The USB plug of the OTG data cable has an identification pin (that is, an ID pin), and the ID pin and the ground (GND) pin are short-circuited. However, the plug used to connect to the terminal side in a common USB data cable does not have an ID pin. However, when the user connect...
