QUICK CHARGING METHOD, POWER ADAPTER AND MOBILE TERMINAL
First Claim
1. A quick charging method, the method comprising:
- coupling a power adapter to a mobile terminal via a Universal Serial Bus (USB) interface, a power line of the USB interface being used for the power adapter to charge the mobile terminal, the power adapter supporting a normal charging mode and a quick charging mode, a charging current corresponding to the quick charging mode being greater than a charging current corresponding to the normal charging mode;
transmitting, by the power adapter, clock signal to the mobile terminal via a first data line of the USB interface in a process of that the power adapter is coupled to the mobile terminal, wherein the clock signal indicates a communication sequence between the power adapter and the mobile terminal;
conducting, by the power adapter, a bidirectional communication with the mobile terminal via a second data line of the USB interface under control of the communication sequence, so as to determine to charge the mobile terminal in the quick charging mode; and
adjusting, by the power adapter, a charging current of the power adapter to the charging current corresponding to the quick charging mode to charge the mobile terminal.
