[0003] During the research and practice of the prior art, the inventor of the present invention found that in the existing implementation, after the master device and the slave device are connected, the master device can only charge the slave device in one direction, while the slave device Cannot provide power to the main device. For example, a laptop can charge a mobile phone, but the mobile phone cannot supply power to the laptop. Therefore, when the battery of the main device of the laptop is low, the power in the battery of the mobile phone cannot be used for emergency , reduced usage of portable devices, and user satisfaction

Embodiment Construction
[0029] Below we will describe the embodiments of the present invention in detail with reference to the accompanying drawings.
[0030] see figure 1 , is a flow chart of a terminal charging method provided in an embodiment of the present invention, the terminal at least includes a main device power supply, in this embodiment, the terminal is a master device, and the second terminal is a slave device, and the method includes :
[0031] Step 101: When the second terminal is connected to the terminal, detect the battery power of the second terminal;
[0032] Wherein, a manner of detecting the battery power of the second terminal is as follows:
[0033] The microprocessor of the terminal obtains the power state of the battery of the second terminal through the connector and the system management bus;
[0034] It is judged whether the power state of the battery of the second terminal is less than a preset first charging threshold, and if less, the following step 102 is performed....

The invention relates to a terminal and a charging and power supplying method thereof. The terminal at least comprises a main equipment power supply. The method comprises the following steps of: detecting the electric quantity of a battery of a second terminal when the second terminal is connected with the terminal; and controlling the main equipment power supply to be connected with the battery of the second terminal when the electric quantity of the battery of the second terminal is smaller than a preset first charging threshold, wherein the main equipment power supply charges the battery of the second terminal so as to ensure that the battery of the second terminal can carry electric energy as much as possible; in addition, the battery of the second terminal can supply power to the terminal and the second terminal under the condition that the electric quantity of the battery of the terminal is low to maintain the terminal and the second terminal to work; and the terminal is convenient for users to use, thereby improving the stability and the accessibility of the terminal.
Description
technical field [0001] The present invention relates to the technical field of terminals, in particular to a terminal charging method, a power supply method and a terminal. Background technique [0002] With the development of terminal technology, two portable devices can be connected and exchange data, such as the connection between a laptop and a mobile phone, and data exchange between a laptop and a mobile phone; The mobile phone is charged in one direction. That is to say, when two portable devices are connected, one acts as a master device and the other acts as a slave device. The master device and the slave device each have an independent battery-powered subsystem. The battery-powered subsystem of the device independently supplies power to the master device and the slave device; when the master device and the slave device are connected, the master device can charge the slave device and perform data interaction. [0003] During the research and practice of the prior a...
