摘要：A power supply terminal, and a charging control method and apparatus aredisclosed, which can solve a problem of relatively poor compatibility of a terminal

charging solution in the prior art. The power supply terminal includes a USB port, aswitch, a power source module, and a processor, where the USB port is configured toconnect to a power receiving terminal; one end of the power source module is connectedto a power source pin VBUS of the USB port and is configured to charge the powerreceiving terminal by using the power source pin VBUS, and the other end of the powersource module is connected to one terminal of the processor; two other terminals of theprocessor are separately connected to two data pins D+ and D- of the USB port; theswitch and the two data pins D+ and D- are connected in parallel to the processor; whenthe switch is on, in a process in which the power source module outputs a voltage tocharge the power receiving terminal, the processor detects that a drop amplitude of theoutput voltage of the power source module exceeds a preset value, and performscontrol to turn off the switch; and controls, when the switch is off, the power sourcemodule to output a voltage to charge the power receiving terminal.
