Abstract

The invention relates to a method for charging a portable device, a charging control method, a charging control device and a charging control system. The method for charging the portable device comprises the steps of acquiring the electric quantity information of the portable device by a USB (Universal Serial Bus) wire; determining that the portable device needs to be charged according to the electric quantity information and sending a charging request to the portable device by the USB wire; if a charging circuit of the portable device is opened according to the charging request, the USB can charge the portable device. According to the disclosed technical scheme, the portable device can be charged by a mobile device when needing to be charged, so that a problem that the portable device with low electric quantity cannot be used under a condition without a charging source is solved; and the mobile device can be used as a standby power supply of the portable device under a specific condition according to the characteristic that the battery capacity of the mobile device is higher than that of the portable device, therefore, the intelligent device experience of a user can be enriched and facilitated greatly.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a method for charging a portable device, a method, a device and a system for controlling charging. Background technique [0002] With the popularity of smart devices, more and more portable devices (such as smart bracelets, smart eyes, smart watches, etc.) are gradually integrated into everyone's living habits. For example, smart bracelets can record the user's exercise and heartbeat Speed, smart watches allow users to view weather conditions and geographic directions in real time, smart glasses can provide users with necessary visual information and so on. When the user is experiencing the convenience and comfort brought by the portable device, if the portable device is set to shut down due to insufficient power at this time, and the user does not carry any bulky charging equipment, in this case due to insufficient power The use experience brought by the por...
