Abstract:
The present disclosure provides a fast charging method, a power adapter, and a mobile terminal. The method includes: transmitting, by the power adapter, a clock signal to the mobile terminal via a first data line of a USB interface in a process of coupling the power adapter with the mobile terminal, where the clock signal is configured for indicating 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 a fast charging mode; and adjusting, by the power adapter, a charging current to be a charging current of the fast charging mode to charge the mobile terminal.

Claim (Index 9):
A mobile terminal, the mobile terminal being coupled with a power adapter via a USB interface, a power line of the USB interface being configured for charging the mobile terminal, a data line of the USB interface being configured for a bidirectional communication between the mobile terminal and the power adapter, the power adapter transmitting a clock signal to the mobile terminal via a first data line of the USB interface in a process of coupling the power adapter with the mobile terminal, the clock signal being configured for indicating a communication sequence between the power adapter and the mobile terminal, the communication sequence containing instruction transmission time slots of the power adapter and instruction reception time slots of the power adapter, and the instruction transmission time slots and the instruction reception time slots being alternatively generated, the mobile terminal supporting a normal charging mode and a fast charging mode, a charging current of the fast charging mode being higher than a charging current of the normal charging mode, the mobile terminal comprising:\n a charging circuit; and a communication control circuit configured to determine to activate the fast charging mode, receive a second instruction from the power adapter, wherein the second instruction is configured for querying whether or not a current output voltage of the power adapter is proper to be a charging voltage of the fast charging mode; the communication control circuit being further configured to transmit a reply instruction corresponding to the second instruction to the power adapter, wherein the reply instruction corresponding to the second instruction is configured for indicating that the current output voltage of the power adapter is proper, high, or low, whereby the power adapter adjusts the current output voltage of the power adapter to be the charging voltage of the fast charging mode according to the reply instruction corresponding to the second instruction; the communication control circuit being further configured to receive a third instruction from the power adapter, wherein the third instruction is configured for querying a maximum charging current currently supported by the mobile terminal; the communication control circuit being further configured to transmit a reply instruction corresponding to the third instruction to the power adapter, wherein the reply instruction corresponding to the third instruction is configured for indicating the maximum charging current currently supported by the mobile terminal, whereby the power adapter determines the charging current of the fast charging mode according to the reply instruction corresponding to the third instruction; the communication control circuit being further configured to receive a fourth instruction from the power adapter after the power adapter adjusts an output current of the power adapter to be the charging current of the fast charging mode and enters a constant current phase, wherein the fourth instruction is configured for querying a current voltage of a battery of the mobile terminal; the communication control circuit being further configured to transmit a reply instruction corresponding to the fourth instruction to the power adapter, wherein the reply instruction corresponding to the fourth instruction is configured for indicating the current voltage of the battery of the mobile terminal, whereby the power adapter adjusts the output current of the power adapter according to the current voltage of the battery to charge the mobile terminal in a multi-stage constant current mode via the charging circuit, wherein each instruction transmitted to the mobile terminal by the power adapter comprises an 8-bit data, and each reply instruction received from the mobile terminal by the power adapter comprises a 10-bit data.
