Document Type and Number:
WIPO Patent Application WO/2017/063192
Kind Code:
A1
Abstract:
A charging method, a mobile terminal (400), and a charging device (500). The method comprises: a mobile terminal (400) receives a level signal sent by a charging device (500) by means of a D- data line in a charging interface so as to determine the type of the charging device (500); and when the charging device (500) is determined to be an adapter or a portable power source, the mobile terminal (400) sends a handshake request signal to the charging device (500) by means of a D+ data line in the charging interface, the handshake request signal being used for inquiring whether the charging device (500) supports a quick charging mode or not. The mobile terminal (400) actively initiates a handshake negotiation process about quick charging, and the mobile terminal (400) performs single-line handshake negotiation with the charging device (500) by means of a D+ data line, such that the problem of possible error of quick charging handshake negotiation in the prior art is resolved.
