The difference of the battery electric quantity of terminal is less than or equal to the second default electricity difference, or, the battery electric quantity of the machine or the terminal reaches
During to default power threshold, stop the machine and interacted with the electricity between the terminal.
For example, terminal B gives terminal A wireless chargings, when be charged to terminal B it is equal with terminal A battery electric quantity when just stop
Charging；Or when terminal B and terminal A battery electric quantity approach, such as the 90% of terminal A electricity incoming terminal B electricity, i.e., two
When terminal power difference is less than or equal to 10%, stop charging；Or can set and be charged to the 20% of terminal A total electricities, or eventually
When holding B total electricities residue 30%, just stop charging.
In alternative, by whether completing to confirm to charging, transmitting terminal is avoided all to fill self electric quantity to connecing
Receiving end, and transmitting terminal self electric quantity deficiency can not be worked；Also, receiving terminal just stops charging after receiving enough electricity,
Emergency management can be completed in time.
Optionally, short-distance wireless communication mode includes：Near field communication (NFC) NFC modes or bluetooth approach.
In alternative, the exchange of terminal battery electricity quantity information can be realized by NFC or bluetooth approach, it is every to cause
Individual terminal determines that itself still sends as the receiving terminal of wireless charging by obtaining the battery level information of itself and other side
End.
Optionally, in the present embodiment, the wireless charging function between terminal can be turned on and off as needed by user.
Only after user opens wireless charging function, just carry out the exchange of battery level information between terminal, so realize terminal it
Between wireless charging.
Fig. 4 is a kind of flow chart of wireless charging method according to another exemplary embodiment, as shown in figure 4, should
Method comprises the following steps.
In step S41, two mobile phone back sides contact with each other.
In step S42, battery level information interaction is carried out by NFC or bluetooth between mobile phone.
In step S43, whether the difference of battery electric quantity between two mobile phones is judged more than 10%, if it is, performing step
S44, if not, complete charge.
In step S44, according to the battery level information of two mobile phones, both sides determine the machine as wireless charging respectively
The role of receiving terminal or transmitting terminal distributes.
