Embodiment Construction
[0054] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and arrangements consistent with aspects of the present disclosure as recited in the appended claims.
[0055] Figure 1A It is a schematic structural diagram of an implementation environment shown according to an exemplary embodiment. The implementation environment may include a first terminal 110 and a second terminal 120, and the first terminal 110 and the second terminal 120 may belong to the same type of terminal, and the two may communicate through a Type C interface. Wherein, th...

The invention relates to a charging method and device. The method comprises steps as follows: residual electricity information of a first terminal is collected; residual electricity information of a second terminal connected with the first terminal is acquired; when the first terminal and the second terminal meet a preset power supply role exchange condition according to master-slave mode information of the first terminal, the residual electricity information of the first terminal and the residual electricity information of the second terminal, a power supply direction between the first terminal and the second terminal is changed. Therefore, the problem that data interaction cannot be performed continuously due to insufficient power supply of the terminals because of power supply from the terminal with low residual electricity to the terminal with high residual electricity in related technologies can be solved. Besides, according to the charging method, the change of the power supply direction can be realized without change of the master-slave mode of the two terminals, and accordingly, the data interaction cannot be influenced.
Description
technical field [0001] The present disclosure relates to the field of terminals, and in particular to a charging method and device. Background technique [0002] With the emergence of the Type C interface, more and more terminal devices begin to adopt this interface. When a terminal device interacts with other terminal devices, the terminal device can be in three different modes, namely: master device mode (DFP mode), slave device mode (UFP mode) and master-slave device mode (DRP mode). When two terminal devices establish a connection through the Type C interface, the probability of the two being in master-slave mode is equal, that is, it can be used as a master device or as a slave device. When two terminal devices establish a connection through the Type C interface, the master device always supplies power to the slave device. At this time, if the power of the master device is insufficient, data interaction will be affected. In addition, in the related art, changing the p...
