Embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following description is related to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
Fig. 1 is a kind of flow chart of charge control method according to an exemplary embodiment, as shown in figure 1, this fills
Electric control method is used in first terminal equipment, comprises the following steps S11-S15：
In step s 11, preset instructions are received.
In step s 12, when preset instructions are the first charging instruction, the USB of first terminal equipment is connect
The ID pins of mouth are converted to ground connection.
Wherein, it using first terminal equipment is instruction that other equipment is charged that the first charging instruction, which is,.
In step s 13, whether the opposite side of the connecting line on the USB of monitoring first terminal equipment
It is connected with the USB of second terminal equipment.
Wherein, the connecting line on the USB of first terminal equipment is that by different equipment or shifting
The connecting line of connection and data exchange between dynamic equipment, such as OTG connecting lines, two side interfaces of OTG connecting lines are with being connected
USB (Universal Serial Bus, USB) interface of two equipment matches.
In step S14, when the opposite side of the connecting line on the USB of first terminal equipment and second
During the USB connection of terminal device, monitoring the ID pins of the USB of second terminal equipment is
No is vacant state.
In step S15, when the ID pins of the USB of second terminal equipment are vacant state, to the
Two terminal devices charge.
The technical scheme provided using the embodiment of the present disclosure, by even between first terminal equipment and second terminal equipment
Wiring is connected and the ID pins of the USB of first terminal equipment and second terminal equipment are connected correctly respectively
When, the process of discharge and recharge can be completed between first terminal equipment and second terminal equipment so that the high terminal device of electricity

When connecting line on USB is disconnected, by the ID pins of the USB of first terminal equipment
Revert to the default setting of first terminal equipment.
In one embodiment, as shown in Fig. 2 the further comprising the steps of S21-S25 of the above method.
In the step s 21, preset instructions are received.
In step S22, when preset instructions are the second charging instruction, the USB of first terminal equipment is connect
The ID pins of mouth are converted to vacant state.
Wherein, the second charging instruction is to utilize instruction of the other-end to first terminal equipment charge.The step can be by
User directly sets the state of the ID pins of USB interface in first terminal equipment, can also be received in first terminal equipment
It is automatically vacant state by the State Transferring of the ID pins of the USB interface of itself during the second charging instruction.
In step S23, whether the opposite side of the connecting line on the USB of monitoring first terminal equipment
It is connected with the USB of third terminal equipment.
In step s 24, when the opposite side of the connecting line on the USB of first terminal equipment and the 3rd
During the USB connection of terminal device, monitoring the ID pins of the USB of third terminal equipment is
No ground connection.
In step s 25, when the ID pins ground connection of the USB of third terminal equipment, by the 3rd eventually
End equipment is charged.
In the present embodiment, drawn by the ID of the connection between first terminal equipment and third terminal equipment, and USB interface
The conversion of the connection status of pin, realizes the process from third terminal equipment to first terminal equipment charge, and the process need not
Larger change is carried out to equipment, so as to improve the Experience Degree of user.
