During formula, then explanation restriction charge mode is the most selected.
Alternatively, when carrying out OTG and connecting, main equipment provides restriction by the mode such as display interface, voice message immediately
The option of charge mode, selects to judge to limit charge mode according to user the most selected.
Such as, pop-up display interface, on display interface, display is include at least two pattern limited including charge mode
Select for user, when user clicks on or choose restriction charge mode, then illustrate to limit charge mode selected.
And for example, pop-up display interface, display interface asks the user whether enter restriction charge mode, when user selects
Enter when limiting charge mode (as clicked on "Yes" or " entrance "), then explanation restriction charge mode is selected.
And for example, voice broadcast selects for user include at least two pattern limited including charge mode, works as user speech
(such as say the option sequence number limiting charge mode) during selectional restriction charge mode, then explanation restriction charge mode is selected.
And for example, whether voice message user enters restriction charge mode, limits charge mode when user speech selects to enter
Time (such as saying "Yes" or " entrance "), then explanation limit charge mode selected.
S102, judgement meet restriction charge condition.
When limiting charge mode and being selected, main equipment judges to meet restriction charge condition.
S103, judgement are unsatisfactory for limiting charge condition.
When limiting charge mode and not having selected, main equipment judges to be unsatisfactory for limiting charge condition.
Thus, user can the most independently choose whether to need to limit output electric current.
In further embodiments, restriction charge condition can be set by presetting operational order.Such as Fig. 3 institute
Showing, main equipment judges whether that the idiographic flow meeting restriction charge condition is:
S201, reception operational order, it may be judged whether receive default operational order.When receiving default operational order

The operational order preset compares, it is judged that whether the two mates.When the two mates, then explanation have received default operation
Instruction；When the two does not mates, then explanation is not received by the operational order preset.
This operational order can be touch control operation, button operation, gesture motion, the shaking motion to main equipment, language high up in the air
A kind of combination of or at least two of the operational motions such as sound order.Wherein, touch control operation includes performing click, length on a display screen
A kind of or the combination of at least two pressed, slide in the operation such as optional position or ad-hoc location, it is specific that button operation i.e. presses one
Button or simultaneously or successively pressing at least two button, gesture motion high up in the air i.e. main equipment is caught by imaging first-class trap setting
The specific action that the staff grasped is made, is specifically shaken by what sensor detected the shaking motion i.e. main equipment of main equipment
Rolling action (such as left and right or preset times of rocking back and forth), voice command i.e. main equipment is gathered by voice collection device (such as MIC)
Special sound.
S202, judgement meet restriction charge condition.
When receiving default operational order, main equipment judges to meet restriction charge condition.
S203, judgement are unsatisfactory for limiting charge condition.
When being not received by the operational order preset, main equipment judges to be unsatisfactory for limiting charge condition.
Thus, output electric current conveniently can be limited by user by operational order.
In further embodiments, restriction charge condition can be set by presetting battery power threshold.Such as Fig. 4
Shown in, main equipment judges whether that the idiographic flow meeting restriction charge condition is:
S301, acquisition battery electric quantity, it is judged that whether battery electric quantity is less than threshold value.When battery electric quantity is less than threshold value, perform
Step S302；When battery electric quantity is not less than threshold value, perform step S303.
Concrete, when carrying out OTG and connecting, main equipment detects the battery electric quantity that the machine is current immediately, or directly from electricity
The battery electric quantity that the machine is current is read in pond management application.The most current battery electric quantity and the size of threshold value, it is judged that battery electric quantity
Whether less than threshold value.
Threshold value can set as required, as set in the range of 50%～10%.
S302, judgement meet restriction charge condition.
When battery electric quantity is less than threshold value, main equipment judges to meet restriction charge condition.
S303, judgement are unsatisfactory for limiting charge condition.
When battery electric quantity is not less than threshold value, main equipment judges to be unsatisfactory for limiting charge condition.
Thus, when detecting that battery current is relatively low, automatically output electric current is limited, to protect the electricity of main equipment
Amount, extends cruising time.
Further, it is also possible to set restriction charge condition by the type from equipment connected, when carrying out OTG and connecting,
Main equipment identification is from the type of equipment, it may be judged whether (storage device type that such as need not power supply (such as carries to belong to specified type
The USB flash disk of power supply, hard disk etc.)), when belonging to specified type, it is judged that meet and limit charge condition, otherwise judge that being unsatisfactory for restriction fills
