Fig. 2 is a schematic flowchart of a charging control method according to an embodiment of the present invention. The main implementation of this embodiment is the charge control device shown in the embodiment of fig. 1. The execution subject of the embodiment is a charging control apparatus.

S110, acquiring charging information for instructing to charge a second user equipment, and determining a first user equipment in a preset equipment set, where all the equipment in the equipment set are user equipment configured with a USB OTG interface circuit.
The charging information may be information sent by the second user equipment to the charging control device, for example, when the second user equipment needs to be charged, the user sends the charging information to the charging control device through the second user equipment.
The charging information may also be information acquired by the charging control device according to an external operation, for example, when the second user device needs to be charged, the user inputs the charging information on the control panel of the charging control device through an external operation manner such as point touch or sliding.
S110 also includes a determination of the second user equipment. The determination manner of the second user equipment may be: the charging information comprises an identifier of second user equipment, and the charging control equipment acquires the identifier of the second user equipment in the charging information so as to determine the second user equipment; or the charging control equipment responds to the charging information and acquires second user equipment corresponding to the charging information according to a preset corresponding relation.
In this embodiment, the determining the first user equipment in the preset device set may be determining the first user equipment in the preset device set according to an external operation. For example, a list of the device sets is displayed to the user, the user inputs the charging information through an external operation manner such as point touching or sliding according to the list information displayed by the charging control device, and the first user device desired to be the charging device is selected.
In this embodiment, the first user equipment is determined in the preset equipment set, or the first user equipment may be automatically determined by the charging control equipment. The embodiment also provides an explanation of the following two implementation manners for automatically determining the first user equipment by the charging control device:
one implementation way for the charging control device to automatically determine the first user device may be: the charging control device determines a default first user device in the saved device set, for example, the user device with the most connection records is determined as the first user device;
another implementation way for the charging control device to automatically determine the first user device may be: the charging control device determines, in the device set, a user device closest to the charging control device as a first user device.
One method of determining the set of devices may be: the charging control device automatically searches connectable USB OTG devices nearby to form the device set, wherein the device set is a set of connectable USB OTG devices.
Another method for determining the set of devices may be: the charge control device automatically searches for a connectable USB OTG device nearby and sends inquiry information on whether to approve the supply of electric power to the connectable USB OTG device. And if the connectable USB OTG equipment receives the inquiry information and then sends information of agreeing to provide electric energy to the charging control equipment, determining that the connectable USB OTG equipment is the equipment in the equipment set, and the equipment set is the set of the USB OTG equipment agreeing to provide electric energy.
The first user equipment and the second user equipment are both equipment with USB OTG interface circuits, namely the user equipment can control the user equipment to be connected with the electric connection path in a role of master equipment or a role of slave equipment by suspending or grounding an ID pin of the USB OTG interface of the user equipment.
For the sake of clarity of the description of the charging control method, in the following description, the first user equipment is used for the user equipment determined as the master device, and the second user equipment is used for the user equipment determined as the slave device.
S120, send a first configuration request to the first user equipment, and send a second configuration request to the second user equipment, where the first configuration request is a request for configuring the first user equipment as a master device, and the second configuration request is a request for configuring the second user equipment as a slave device.
The first user equipment can be another user equipment owned by the user, for example, when the mobile phone is not powered on, the tablet computer is used as the first user equipment to charge the mobile phone; the mobile phone may be a device borrowed from another person, for example, a mobile phone which borrows full electric quantity of another person when the mobile phone is out of power is used as the first user device to charge the mobile phone for a short time. The signal transmission modes of the charging control device, the first user equipment and the second user equipment can be WIFI network connection transmission and mobile network connection transmission. The mobile network may be a 2G, 3G or 4G network. The mobile network connection transmission mode may be, for example, a mode of sending and receiving a short message.
There are 5 pins in the USB OTG interface circuit: 2 pieces of differential data (D + pin, D-pin) are transmitted; 1 is a power supply pin (VBUS pin); 1 is a ground pin (GND pin); the 1 bar is an identification pin (ID pin). The ID pins are used to identify different cable endpoints. When the USB OTG equipment detects that the ID pin is grounded, the USB OTG equipment is controlled to be used as main equipment to supply power to the outside by default; and when the ID pin is detected to be empty, the control is used as the slave equipment to receive the charging of the master equipment by default.
After the first user equipment receives the first configuration request, grounding a detection end of an ID pin of the USB interface according to the first configuration request, and configuring the first user equipment as main equipment. Correspondingly, after receiving a second configuration request, the second user equipment suspends the detection end of the ID pin of the USB interface according to the second configuration request, and configures the second user equipment as slave equipment.

And the second user equipment receives the identifier of the first user equipment and displays the identifier to a user, the user finds the first user equipment according to the identifier of the first user equipment, and connects the first user equipment, the second user equipment and the charging control equipment with each other to form a connection structure shown in fig. 1, and an electric connection path is formed between the first user equipment and the second user equipment. At this time, since the first user equipment and the second user equipment are already respectively the master equipment and the slave equipment, the electric current flowing from the first user equipment to the second user equipment exists in the electric connection path between the first user equipment and the second user equipment.
And S140, if it is determined that the first user equipment is electrically connected with the second user equipment, boosting the first voltage of the first user equipment to obtain a second voltage with a voltage value of a preset voltage value, and charging the second user equipment with the second voltage.
In an electric connection path between the first user equipment and the second user equipment, the output voltage of the first user equipment is boosted, so that the charging speed of the second user equipment can be increased, and the charging current can be increased. For example, the second user equipment is charged after the voltage of 4.2V is increased to the voltage of 5V. The boosting mode can be that a direct current-direct current boosting circuit is arranged on a charging path of the first user equipment and a charging path of the second user equipment.
In this embodiment, a first user equipment is determined in a preset equipment set by acquiring charging information for instructing to charge a second user equipment, where all the equipment in the equipment set are user equipment configured with a USB OTG interface circuit; sending a first configuration request to the first user equipment, and sending a second configuration request to the second user equipment, wherein the first configuration request is a request for configuring the first user equipment as a master device, and the second configuration request is a request for configuring the second user equipment as a slave device; if first feedback information sent by the first user equipment and second feedback information sent by the second user equipment are received, sending an identifier of the first user equipment to the second user equipment, wherein the identifier of the first user equipment is used for indicating that equipment capable of charging the second user equipment is the first user equipment, the first feedback information is used for indicating that the first user equipment completes configuration according to the first configuration request, and the second feedback information is used for indicating that the second user equipment completes configuration according to the second configuration request; and if the first user equipment is determined to be electrically connected with the second user equipment, boosting the first voltage of the first user equipment to obtain a second voltage with a voltage value of a preset voltage value, and charging the second user equipment with the second voltage.
