End equipment A is by electric terminals, and terminal device B is power supply terminal.
Power supply terminal with connected by charge cable by electric terminals after, start to charge to by electric terminals in power supply terminal
Before, power supply terminal first obtains the first battery information of itself, and the first battery information may include that the first of the battery of power supply terminal remains
Remaining electricity may also include the first standby time of power supply terminal, may also include other information.
Wherein, power supply terminal can obtain the according to the first remaining capacity and current operation mode of the battery of power supply terminal
One standby time, acquisition methods are method in the prior art, are repeated no more in the present embodiment.
In a kind of optional mode, the content type that the first battery information includes can be that user passes through power supply terminal
Interface input, for example after power supply terminal by electric terminals with being connected, power supply terminal can show the first interface, be shown on the first interface
It is shown with the input frame for the content type for inputting or selecting the first battery information to include for user.
For example, Fig. 3 is the user interface schematic diagram of terminal provided by the embodiments of the present application, referring to Fig. 3, on the first interface 31
Pull-down input frame is shown, the project in drop-down list 31 may be selected in user, and the project in drop-down list 31 is first
The content type that battery information includes illustrates the content type that the first battery information includes if user has selected remaining capacity
For remaining capacity the battery of itself can be obtained after power supply terminal receives instruction of the user by selecting remaining capacity input
The first remaining capacity.
In another optional mode, terminal is written when can dispatch from the factory with terminal in the content type that the first battery information includes
Equipment, that is, default setting.
Start before being charged by electric terminals in power supply terminal, after power supply terminal obtains the first battery information of itself,

Specifically, start before being powered by electric terminals in power supply terminal, if the cells that power supply terminal obtains is standby
Duration is less than or equal to the second predetermined threshold value, then does not start to the process powered by electric terminals, that is, control power supply terminal is not
It powers to by electric terminals.At this point, terminal can display alarm message, reminder message be used to indicate power supply terminal can not to by it is electric eventually
End power supply.
Correspondingly, if the first standby time is more than the second predetermined threshold value, start to the process powered by electric terminals, that is, to control
Power supply terminal processed is powered to by electric terminals.
It is understood that starting after being powered by electric terminals in power supply terminal, as power supply terminal is to be supplied by electric terminals
The standby time of the progress of electric process, power supply terminal can be gradually reduced.At this point, starting to power to by electric terminals in power supply terminal
Afterwards, power supply terminal can at interval of preset duration obtain one-shot battery standby time, and by obtained during this it is standby when
Length, when the standby time of acquisition is less than or equal to the second predetermined threshold value, stops to by electric terminals compared with the second predetermined threshold value
Power supply controls power supply terminal and does not power to by electric terminals, when the standby time of acquisition is more than the second predetermined threshold value, then continues
It powers to by electric terminals, i.e., power supply terminal continues to keep the state to being powered by electric terminals.
Wherein, preset duration can be any in 2min~5min.
In the present embodiment, when terminal device is as power supply terminal, by obtaining the battery information of itself, according to itself
Battery information is realized and controls itself purpose to the state powered by electric terminals, you can realizes the electricity of itself in power supply process
Measure the purpose not being depleted.
Below to this application involves the method for another reverse charging illustrate.
Fig. 4 is the flowchart 2 of the method for reverse charging provided by the embodiments of the present application, as shown in figure 4, the present embodiment
Method may include：
Step S201, the first request is sent to by electric terminals, and the first request, which is used to indicate, to be obtained by electric terminals by electric terminals
