The following describes a specific implementation process of the present application in detail by using specific embodiments with reference to the accompanying drawings.

Fig. 2 is a flowchart of an embodiment of a charging method provided in the present application, where an execution main body in the embodiment may be a slave device shown in fig. 1, and the slave device is connected to a master device through a connection line, as shown in fig. 2, the method of the present embodiment may include:
s101, acquiring the current residual capacity of the master equipment and the current residual capacity of the slave equipment at preset time intervals.
The obtaining of the current remaining power of the master device may be receiving the current remaining power of the master device sent by the connection established by the master device through the connection line. The connection line connecting the slave device and the master device may be a USB connection line. The obtaining of the current remaining power of the slave device may be reading the current remaining power of the slave device. In the embodiment of the present application, the remaining battery capacity is a percentage of the remaining battery capacity to the total battery capacity, such as 50%, 80%, and so on.
S102, whether the current residual capacity of the master device and the current residual capacity of the slave device meet a first preset condition is determined.
The first preset condition may be: the current remaining capacity of the master device is less than the current remaining capacity of the slave device. For example, the current remaining capacity of the master device is 40%, the current remaining capacity of the slave device is 50%, and the current remaining capacity of the master device is smaller than the current remaining capacity of the slave device.
The first preset condition may also be: the difference value between the current residual capacity of the master device and the current residual capacity of the slave device is smaller than a first preset threshold value. For example, the first preset threshold is 5%, that is, the difference between the current remaining power of the master device and the current remaining power of the slave device is less than 5%. This avoids frequent activation of the turn-off or turn-on of the pass current from the master device to the slave device, for example, once charging has begun, the turn-off of the pass current from the master device to the slave device (i.e., stopping charging) may occur after the master device has less than 3% of the slave device charge.
Specifically, after the slave device is connected to the master device, the master device starts to charge the slave device, and acquires the current remaining power of the master device and the current remaining power of the slave device every preset time, for example, every preset time is 10S or 1 minute, determines the current remaining power of the master device and the current remaining power of the slave device, determines whether to continue charging, and if it is determined that the current remaining power of the master device and the current remaining power of the slave device meet a first preset condition, executes S103.
S103, if the first preset condition is met, setting the path current of the master device entering the slave device to be smaller than or equal to a preset current threshold.
Specifically, for example, the preset current threshold is 50mA, the path current of the master device entering the slave device is set to be less than 50mA, and if the preset current threshold is 0, the path current of the master device entering the slave device is set to be 0, that is, the path current of the master device entering the slave device is turned off. Therefore, the situation that the slave equipment needs to be charged when the electric quantity of the main equipment is insufficient can be avoided, and the electric quantity of the main equipment is ensured.
Optionally, before S101, the method of this embodiment may further include:
and S104, acquiring the initial residual capacity of the master equipment and the initial residual capacity of the slave equipment.
Specifically, after the slave device is connected to the master device, before the master device starts charging the slave device, the initial remaining capacity of the master device and the initial remaining capacity of the master device are obtained, where the obtained initial remaining capacity of the master device may be the initial remaining capacity of the master device sent by receiving a connection established by the master device through a connection line. That is, after the master device determines to connect to the slave device, the initial remaining power of the master device itself is read and then transmitted to the slave device. The obtaining of the initial remaining power of the slave device may be reading the initial remaining power of the slave device. In the embodiment of the present application, the remaining battery capacity is a percentage of the remaining battery capacity to the total battery capacity, such as 50%, 80%, and so on.
And S105, determining whether the initial residual capacity of the master equipment and the initial residual capacity of the slave equipment meet a second preset condition.
Wherein, the second preset condition may be: the initial remaining capacity of the master device is greater than or equal to the initial remaining capacity of the slave device.
The second preset condition may also be: the difference value between the initial residual capacity of the master device and the initial residual capacity of the slave device is greater than or equal to a second preset threshold value.
It should be noted that the first preset threshold and the second preset threshold may be the same or different.
And S106, if the second preset condition is met, starting the path current of the master equipment into the slave equipment.
And S107, if the second preset condition is determined not to be met, setting the path current of the master device entering the slave device to be less than or equal to a preset current threshold.
Specifically, for example, the initial remaining capacity of the master device is 60%, the remaining capacity of the slave device is 50%, and 60% is greater than 50%, the slave device turns on the pass current of the master device into the slave device, that is, turns on the charging mode.
If it is determined that the initial remaining power of the master device is less than the initial remaining power of the slave device, for example, the initial remaining power of the master device is 40% and the remaining power of the slave device is 50%, the path current of the master device entering the slave device is set to be less than or equal to a preset current threshold, for example, the preset current threshold is 50mA, the path current of the master device entering the slave device is set to be less than 50mA, and if the preset current threshold is 0, the path current of the master device entering the slave device is set to be 0, that is, the path current of the master device entering the slave device is turned off. Therefore, the situation that the slave equipment needs to be charged when the electric quantity of the main equipment is insufficient can be avoided, and the electric quantity of the main equipment is ensured.
In this embodiment, when the two devices are connected, the remaining power of the two devices is determined, and whether to start the access current of the master device to the slave device is determined, so that the situation that the slave device needs to be charged when the power of the master device is insufficient can be avoided, and the power consumption of the master device is ensured.
According to the charging method provided by the embodiment, after the slave device is connected with the master device through the connecting line, the current residual capacity of the master device and the current residual capacity of the slave device are obtained at preset time intervals, when it is determined that the current residual capacity of the master device and the current residual capacity of the slave device meet a first preset condition, the path current of the master device entering the slave device is set to be smaller than or equal to a preset current threshold, when the preset current threshold is 0, the path current of the master device entering the slave device is closed, the residual capacity is the percentage of the residual battery capacity to the total battery capacity, so that the residual capacity of the master device is not smaller than the residual capacity of the slave device, the capacities of the master device and the slave device are kept balanced, and the use capacity of the master device is guaranteed.
The following describes the technical solution of the embodiment of the method shown in fig. 2 in detail by using a specific embodiment.
Fig. 3 is a flowchart of an embodiment of a charging method provided in the present application, where an execution main body in the embodiment may be the slave device shown in fig. 1, and the slave device is connected to the master device through a connection line, as shown in fig. 3, the method of the present embodiment may include:
s201, acquiring initial residual capacity of the master device and initial residual capacity of the slave device, wherein the residual capacity is the percentage of the residual battery capacity to the total battery capacity.
S202, judging whether the difference value between the initial residual capacity of the master device and the initial residual capacity of the slave device is larger than or equal to a preset threshold value.
If so, S204 is executed, otherwise, S203 is executed.
In this embodiment, it is described as an example that whether the difference between the initial remaining capacity of the master device and the initial remaining capacity of the slave device is greater than or equal to the preset threshold is determined, and in S202, it may also be determined whether the initial remaining capacity of the master device is greater than or equal to the initial remaining capacity of the slave device.
Specifically, for example, if the initial remaining power of the master device is 60%, the remaining power of the slave device is 50%, the preset threshold is 5%, and the difference between the two is 10%, the step S204 is executed to turn on the path current of the master device into the slave device.
S203, setting the path current of the master device entering the slave device to be less than or equal to a preset current threshold value.
And S204, starting the path current of the master device entering the slave device.
And S205, acquiring the current residual capacity of the master equipment and the current residual capacity of the slave equipment at preset time intervals.
And S206, judging whether the difference value between the current residual capacity of the master equipment and the current residual capacity of the slave equipment is larger than or equal to a preset threshold value.
If yes, the process continues to step S205, otherwise, the process proceeds to step S203.
In this embodiment, it is described as an example that whether the difference between the current remaining capacity of the master device and the current remaining capacity of the slave device is greater than or equal to the preset threshold is determined, and in S202, it may also be determined whether the current remaining capacity of the master device is greater than or equal to the current remaining capacity of the slave device.
The method of the embodiment can ensure that the residual electric quantity of the master device is not less than the residual electric quantity of the slave device, ensure that the electric quantities of the master device and the slave device are kept balanced, and ensure the use electric quantity of the master device. It does not happen that the power of the master device is not enough to be used and the slave device is charged.
It should be noted that the method of this embodiment may also be used in a master device, fig. 4 is a flowchart of an embodiment of a charging method provided in this application, an execution subject in this embodiment may be the master device shown in fig. 4, and the master device is connected to a slave device through a connection line, as shown in fig. 4, the method of this embodiment may include:
s301, acquiring the current residual capacity of the master device and the current residual capacity of the slave device at preset time intervals.
The obtaining of the current remaining power of the slave device may be receiving the current remaining power of the slave device sent by the connection established by the slave device through the connection line. The connection line connecting the slave device and the master device may be a USB connection line. The master device obtains its current remaining power, which may be reading its current remaining power. In the embodiment of the present application, the remaining battery capacity is a percentage of the remaining battery capacity to the total battery capacity, such as 50%, 80%, and so on.
S302, whether the current residual capacity of the master device and the current residual capacity of the slave device meet a first preset condition is determined.
The first preset condition may be: the current remaining capacity of the master device is less than the current remaining capacity of the slave device. For example, the current remaining capacity of the master device is 40%, the current remaining capacity of the slave device is 50%, and the current remaining capacity of the master device is smaller than the current remaining capacity of the slave device.
The first preset condition may also be: the difference value between the current residual capacity of the master device and the current residual capacity of the slave device is smaller than a first preset threshold value. For example, the first preset threshold is 5%, that is, the difference between the current remaining power of the master device and the current remaining power of the slave device is less than 5%. This avoids frequent activation of the turn-off or turn-on of the pass current from the master device to the slave device, for example, once charging has begun, the turn-off of the pass current from the master device to the slave device (i.e., stopping charging) may occur after the master device has less than 3% of the slave device charge.
Specifically, after the slave device is connected to the master device, the master device starts to charge the slave device, and acquires the current remaining power of the master device and the current remaining power of the slave device every preset time, for example, every preset time is 10S or 1 minute, determines the current remaining power of the master device and the current remaining power of the slave device, determines whether to continue charging, and if it is determined that the current remaining power of the master device and the current remaining power of the slave device satisfy the first preset condition, S303 is executed.
And S303, if the first preset condition is met, setting the path current flowing into the slave equipment from the master equipment to be less than or equal to a preset current threshold.
Specifically, for example, the preset current threshold is 50mA, the path current flowing into the slave device from the master device is set to be less than 50mA, and if the preset current threshold is 0, the path current flowing into the slave device from the master device is set to be 0, that is, the path current flowing into the slave device from the master device is turned off. Therefore, the situation that the slave equipment needs to be charged when the electric quantity of the main equipment is insufficient can be avoided, and the electric quantity of the main equipment is ensured.
Optionally, before S301, the method of this embodiment may further include:
s304, acquiring the initial residual capacity of the master device and the initial residual capacity of the slave device.
Specifically, after the slave device is connected to the master device, before the master device starts charging the slave device, the initial remaining capacity of the master device and the initial remaining capacity of the slave device are obtained, where obtaining the initial remaining capacity of the slave device may be receiving the initial remaining capacity of the slave device sent by the connection established by the slave device through the connection line. That is, after the slave device determines to connect to the master device, the initial remaining power of the slave device itself is read and then transmitted to the master device. The master device obtains its initial remaining power, which may be reading its initial remaining power. In the embodiment of the present application, the remaining battery capacity is a percentage of the remaining battery capacity to the total battery capacity, such as 50%, 80%, and so on.
S305, determining whether the initial residual capacity of the master device and the initial residual capacity of the slave device meet a second preset condition.
Wherein, the second preset condition may be: the initial remaining capacity of the master device is greater than or equal to the initial remaining capacity of the slave device.
The second preset condition may also be: the difference value between the initial residual capacity of the master device and the initial residual capacity of the slave device is greater than or equal to a second preset threshold value.
It should be noted that the first preset threshold and the second preset threshold may be the same or different.

And S307, if the second preset condition is determined not to be met, setting the path current flowing into the slave equipment from the master equipment to be less than or equal to a preset current threshold.
Specifically, for example, the initial remaining capacity of the master device is 60%, the remaining capacity of the slave device is 50%, and 60% is greater than 50%, the master device turns on the pass current flowing from the master device to the slave device, that is, turns on the charging mode.
If it is determined that the initial remaining power of the master device is less than the initial remaining power of the slave device, for example, the initial remaining power of the master device is 40% and the remaining power of the slave device is 50%, the path current flowing into the slave device from the master device is set to be less than or equal to a preset current threshold, for example, the preset current threshold is 50mA, the path current flowing into the slave device from the master device is set to be less than 50mA, and if the preset current threshold is 0, the path current flowing into the slave device from the master device is set to be 0, that is, the path current flowing into the slave device from the master device is turned off. Therefore, the situation that the slave equipment needs to be charged when the electric quantity of the main equipment is insufficient can be avoided, and the electric quantity of the main equipment is ensured.
In this embodiment, when the two devices are connected, the remaining power of the two devices is determined, and whether to start the path current flowing from the master device to the slave device is determined, so that the situation that the slave device needs to be charged when the power of the master device is insufficient can be avoided, and the power consumption of the master device is ensured.
According to the charging method provided by the embodiment, after the master device is connected with the master device through the connecting line, the current residual capacity of the master device and the current residual capacity of the slave device are obtained at preset time intervals, when it is determined that the current residual capacity of the master device and the current residual capacity of the slave device meet a first preset condition, the path current flowing into the slave device from the master device is set to be smaller than or equal to a preset current threshold, when the preset current threshold is 0, the path current flowing into the slave device from the master device is closed, and the residual capacity in the embodiment is the percentage of the residual battery capacity to the total battery capacity, so that the residual capacity of the master device is not smaller than the residual capacity of the slave device, the capacities of the master device and the slave device are guaranteed to be balanced, and the use capacity of the master.
