When type is preset kind, judge whether the load capacity of USB interface meets the first predetermined threshold value, meeting the first predetermined threshold value
When, it can be charging modes corresponding to the preset kind to be considered as charging modes corresponding to the USB interface.It is for example, described default
Type is USB3.0, and first predetermined threshold value is 700 milliamperes, then, reaches 700 MAHs in the load capacity of the USB interface,
It can be the first charging modes corresponding to USB3.0 interface types then to think charging modes corresponding to the USB interface.
When the interface type of the USB interface is preset kind, judge whether the load capacity of the USB interface meets
First predetermined threshold value specifically includes：When the interface type of the USB interface is preset kind, receives computer and pass through USB interface

Current value is 700 milliamperes, and the magnitude of voltage that the charging circuit of terminal is detected in subsequent time is 4.5V, less than the second predetermined threshold value
4.6V, the then 700 milliamperes of load capacities as the USB interface of stepped current value detected last moment.
If the magnitude of voltage is more than the second predetermined threshold value, and current stepped current value not yet reaches the USB interface pair
The default load capacity answered, then terminal continue to computer input stepped electric current.Wherein, the default load capacity can be with
The load capacity marked for the interface type of the USB interface.
Further, it is further comprising the steps of：If the load capacity of the USB interface is less than the 3rd threshold value, close

For example, stepped electric current is 100 milliamperes of electric currents to 1 peace and at intervals of 100 milliamperes, then, and the described 4th default threshold
Value can be 500 milliamperes, and the load capacity value of the USB interface can be 1 peace, then terminal instruction computer passes through the USB interface
To terminal input from 500 milliamperes to the stepped electric current of 1 peace.
The benefit so set is：Inputted to terminal from the 4th predetermined threshold value to the load capacity value of the USB interface
Stepped electric current, rather than (for example, 100 milliamperes) are inputted since the electric current of stepped current minimum, meeting safe fill
On the premise of electricity, the speed to terminal charge can be accelerated.
