For example, the host device may enable its Wi-Fi module to operate in an AP (Access Point) mode, and the extension device may enable its Wi-Fi module to operate in an STA (Station) mode, so that the extension device may establish a Wi-Fi connection with the host device.
It should be noted that the execution main body of the charging control method may be the charging control device provided in the embodiment of the present application, or a split electronic device integrated with the charging control device, where the charging control device may be implemented in a hardware or software manner.

101. and detecting whether a charging interface of the host device is connected with the power adapter.
It should be noted that, in this embodiment of the application, the host device and the extension device are both provided with metal connecting pieces such as a spring piece or a spring contact pin connector, and when the extension device and the host device are spliced together, the extension device and the host device establish electrical connection through respective metal connecting pieces, so that the extension device can reuse a charging interface of the host device. The physical representation of the charging interface may be a universal serial bus interface, and it should be understood that the universal serial bus interface includes, but is not limited to, a standard universal serial bus interface, a micro universal serial bus interface, a mini universal serial bus interface, and the like.
In this embodiment of the present application, when detecting whether a charging interface of a host device is connected to a power adapter, it may be detected according to a universal serial bus protocol whether a universal serial bus interface serving as the charging interface is connected to an external device, and when the universal serial bus interface is connected to the external device, a device type enumeration operation is performed to determine whether the connected external device is the power adapter or other types of universal serial bus devices (e.g., a usb disk).

How to perform bidirectional communication between the host device and the external power supply may be performed based on a charging protocol preconfigured by the target device and the external power supply, which is not specifically limited in the embodiment of the present application.
After the target charging current required to be provided by the power adapter is determined, the target device is controlled to send a charging instruction to the power adapter through a communication loop between the target device and the power adapter, the power adapter is instructed to start providing the previously determined target charging current, and since the power adapter only establishes a charging loop with the target device, the target charging current provided by the power adapter is directly provided to a battery of the target device for charging through the charging loop between the power adapter and the target device.
Therefore, in the embodiment of the application, the split type electronic device comprises the host device and at least one extension device, the extension device multiplexes the charging interface of the host device, when the split type electronic device is charged, whether the charging interface of the host device is connected with the power adapter can be detected firstly, and if yes, the target device needing to be charged is determined from the host device and the extension device. Then, a charging loop and a communication loop are established between the target device and the power adapter based on the charging interface of the host device, and the target device is controlled to perform bidirectional communication with the power adapter based on the established communication loop to determine a target charging current required to be provided by the power adapter. And finally, based on the established charging loop, providing the target charging current provided by the power adapter to the target device for charging. Therefore, charging interfaces do not need to be arranged on the host equipment and the extension equipment, and a user does not need to charge the host equipment and the extension equipment respectively, so that the convenience of charging the split type electronic equipment is improved.
Referring to fig. 3, fig. 3 is another schematic flow chart of a charging control method according to an embodiment of the present disclosure. The charging control method can be applied to a split type electronic device, the split type electronic device includes a host device and at least one extension device, and the extension device multiplexes a charging interface of the host device, as shown in fig. 3, the flow of the charging control method can be as follows:
201. and detecting whether a charging interface of the host device is connected with the power adapter.
It should be noted that, in this embodiment of the application, the host device and the extension device are both provided with metal connecting pieces such as a spring piece or a spring contact pin connector, and when the extension device and the host device are spliced together, the extension device and the host device establish electrical connection through respective metal connecting pieces, so that the extension device can reuse a charging interface of the host device. The physical representation of the charging interface may be a universal serial bus interface, and it should be understood that the universal serial bus interface includes, but is not limited to, a standard universal serial bus interface, a micro universal serial bus interface, a mini universal serial bus interface, and the like.
In this embodiment of the present application, when detecting whether a charging interface of a host device is connected to a power adapter, it may be detected according to a universal serial bus protocol whether a universal serial bus interface serving as the charging interface is connected to an external device, and when the universal serial bus interface is connected to the external device, a device type enumeration operation is performed to determine whether the connected external device is the power adapter or other types of universal serial bus devices (e.g., a usb disk).
202. And if the charging interface of the host equipment is connected with the power adapter, determining target equipment needing to be charged from the host equipment and the extension equipment.
If the charging interface of the host device is not connected with the power adapter, whether the charging interface of the host device is connected with the power adapter is continuously detected until the charging interface of the host device is connected with the power adapter is detected. And if the charging interface of the host equipment is connected with the power adapter, determining target equipment needing to be charged from the host equipment and the extension equipment included in the split type electronic equipment according to a preset screening rule.
It should be noted that, the screening rule in the embodiment of the present application is not particularly limited, and may be set by a person skilled in the art according to actual needs.
For example, the host device may be set to prioritize, i.e., directly determine the host device as the target device that needs to be charged. The priority that the remaining operation duration is shortest may also be set, that is, the device with the shortest remaining operation duration in the host device and the extension device is determined as the target device that needs to be charged, and the like.
203. Connecting a power line of the charging interface with a power line of the target device, so that the power line of the target device is connected with a power line of the power adapter, and a charging loop is established between the target device and the power adapter;
204. and switching on the data line of the charging interface and the data line of the target device, so that the data line of the target device is switched on with the data line of the power adapter, and a communication loop is established between the target device and the power adapter.
In the embodiment of the application, after the target device (which may be the host device or the extension device) to be charged is determined from the host device and the extension device included in the split electronic device, a charging loop and a communication loop are established between the target device and the power adapter based on the charging interface of the host device. It should be noted that, at the same time, the charging interface of the host device only enables a charging loop and a communication loop to be established between one target device (which may be the host device or an extension device) and the power adapter.
When a charging loop and a communication loop are established between the target device and the power adapter based on the charging interface of the host device, the power line of the charging interface and the power line of the target device can be connected, so that the power line of the target device is connected with the power line of the power adapter to establish the charging loop between the target device and the power adapter, and the data line of the charging interface and the data line of the target device are connected, so that the data line of the target device is connected with the data line of the power adapter to establish the communication loop between the target device and the power adapter.
For example, referring to fig. 4, in the charging scenario shown in fig. 4, the host device includes a processor, a battery, a charging switch (which may be implemented by MOS transistors connected back to back), a switching module (which may be implemented by a switching chip, for example), and a charging interface, and the extension device includes a processor, a battery, and a charging switch.
For example, if the host device determines the target device, since the power adapter is connected to the charging interface, the power line of the power adapter is connected to the power line of the charging interface, and at this time, the processor of the host device controls the charging switch of the host device to be turned on (and sends the indication information to the extension device, indicating that the processor of the extension device controls the charging switch of the extension device to be turned off), so as to connect the power line of the charging interface to the power line of the battery of the host device, and thus, the power line of the battery of the host device is connected to the power line of the power adapter, so as to establish a charging loop between the host device and the power adapter. In addition, due to the connection of the power adapter, the data line of the charging interface is connected with the data line of the power adapter, and at the moment, the switching module is controlled to be connected with the data line of the charging interface and the data line of the processor of the host device based on the processor of the host device, so that the data line of the processor of the host device is connected with the data line of the power adapter, and a communication loop of the host device and the power adapter is established.
If the target equipment is determined by the extension equipment, because the power adapter is connected to the charging interface, the power line of the power adapter is connected with the power line of the charging interface, the processor based on the host equipment controls the charging switch of the host equipment to be switched off at the moment, and sends indication information to the extension equipment, and the processor of the extension equipment is indicated to control the charging switch of the extension equipment to be switched on, so that the power line of the charging interface is connected with the power line of the battery of the extension equipment, and the charging loop of the extension equipment and the power adapter is established. In addition, due to the connection of the power adapter, the data line of the charging interface is connected with the data line of the power adapter, and at the moment, the switching module is controlled to connect the data line of the charging interface with the data line of the processor of the extension device based on the processor of the host device, so that the data line of the processor of the extension device is connected with the data line of the power adapter, and a communication loop of the extension device and the power adapter is established.
205. And controlling the target device to receive a mode inquiry request sent by the power adapter based on the established communication loop, wherein the mode inquiry request is used for inquiring whether the target device is charged in a preset charging mode.
206. Whether the target device supports a preset charging mode is detected.
207. If so, controlling the target device to return mode response information for indicating agreement to adopt the preset charging mode to the power adapter based on the established communication loop, so that the power adapter determines the charging current corresponding to the preset charging mode as the target charging current required to be provided.
In the embodiment of the present application, the power adapter supports a normal charging mode and a fast charging mode, where the normal charging mode (or referred to as a standard charging mode) may be understood as a charging mode in which a rated charging voltage is 5V (volts) and a rated charging current is less than 2.5A (amperes). The charging speed of the fast charging mode (or called direct charging mode) is higher than that of the normal charging mode. In one embodiment, the charging current and/or charging voltage in the fast charging mode is greater than the charging current and/or charging voltage in the normal charging mode, for example, the charging current in the fast charging mode is greater than 3A, or the charging voltage in the fast charging mode is 9V, 12V, or 15V, etc. The following description will be made with reference to a preset charging mode as a quick charging mode.
For example, based on a communication loop between the target device and the power adapter, the target device may be controlled to receive a mode inquiry request sent by the power adapter, where the mode inquiry request is used to inquire whether to turn on the fast charging mode. Then, whether the target equipment supports the rapid charging mode is detected and determined according to the mode inquiry request, if the target equipment supports the rapid charging mode currently, the target equipment is controlled to send mode response information which agrees to start the rapid charging mode to the power adapter, and the power adapter determines the charging current corresponding to the rapid charging mode as the target charging current required to be provided; if the target device is detected not to support the rapid charging mode currently (for example, the target device only supports the ordinary charging mode, or the remaining battery capacity of the target device is too high), the target device is controlled to send a mode response message for refusing to start the rapid charging mode to the power adapter, so that the power adapter determines the charging current corresponding to the ordinary charging mode as the target charging current required to be provided.
208. And providing the target charging current provided by the power adapter to the target equipment for charging based on the established charging loop.
After the target charging current required to be provided by the power adapter is determined, the target device is controlled to send a charging instruction to the power adapter through a communication loop between the target device and the power adapter, the power adapter is instructed to start providing the previously determined target charging current, and since the power adapter only establishes a charging loop with the target device, the target charging current provided by the power adapter is directly provided to a battery of the target device for charging through the charging loop between the power adapter and the target device.
In one embodiment, the "determining a target device to be charged from the host device and the extension device" includes:
acquiring the residual electric quantity of the host equipment and acquiring the residual electric quantity of the extension equipment;
and determining the device with the lowest residual electric quantity in the host device and the extension device as the target device.
In the embodiment of the application, the target device needing to be charged can be determined according to the residual electric quantity of the host device and the extension device.
For example, the device with the lowest remaining power in the host device and the extension device may be used as the target device to be charged. Therefore, in order to determine the target device to be charged, the remaining power of the host device and the remaining power of the extension device need to be obtained first. It should be noted that the remaining capacity of the host device refers to the remaining capacity of the battery in the host device, and the remaining capacity of the extension device refers to the remaining capacity of the battery in the extension device.
In order to acquire the residual electric quantity of the host equipment and the extension equipment, electric meters are respectively arranged in the host equipment and the extension equipment and used for estimating the residual electric quantity of a battery in the equipment where the electric meters are arranged.
The electricity meter may estimate the remaining capacity of the battery in the device using an open-circuit voltage method, a battery modeling method, or a coulometry method, and may also estimate the remaining capacity of the battery using other methods not listed in the embodiments of the present application, which is not limited in the embodiments of the present application.
For example, when a battery modeling method is adopted, a comparison relation table of voltage and remaining capacity is pre-established according to a discharge curve of the battery, and the comparison relation table describes a corresponding relation between the voltage of the battery and the remaining capacity of the battery. Correspondingly, when the residual capacity of the battery needs to be estimated, the voltage of the battery is measured firstly, and then the residual capacity corresponding to the voltage is inquired in the comparison relation table.
Accordingly, when the remaining power of the host device is obtained, the remaining power estimated by the fuel gauge built in the host device can be directly read. When the residual electric quantity of the extension equipment is acquired, the host equipment can be controlled to send an electric quantity acquisition request to the extension equipment through the wireless communication connection established between the host equipment and the extension equipment, and the extension equipment is instructed to return the residual electric quantity. On the other hand, when receiving a power acquisition request from the host device, the slave device reads the remaining power estimated by the fuel gauge built in itself, and returns the read remaining power to the host device through the wireless communication connection between the slave device and the host device. Therefore, the residual electric quantity of each extension device can be acquired.
After acquiring the residual electric quantity of the host device and the residual electric quantity of the extension device, further determining the device with the lowest residual electric quantity from the host device and the extension device, and determining the device with the lowest residual electric quantity as the target device needing to be charged.
For example, assuming that the split-type electronic device includes a host device a, an extension device B, and an extension device C, a represents the remaining power of the host device a, B represents the remaining power of the extension device B, and C represents the remaining power of the extension device C, if a > B > C, that is, the extension device C is the device with the lowest remaining power among the host device a, the extension device B, and the extension device C, at this time, the extension device C may be determined as the target device that needs to be charged.
In an embodiment, the charging control method provided in the embodiment of the present application further includes:
in the charging process of the target device, the increased electric quantity of the target device is detected.
And if the increased electric quantity of the target equipment reaches the preset electric quantity, determining the target equipment needing to be charged again from the host equipment and the extension equipment.
In the process of supplying the target charging current provided by the power adapter to the target device for charging, the real-time remaining power of the target device may be obtained according to a preset detection period (a suitable value may be obtained by a person skilled in the art according to actual needs, for example, the detection period may be configured to be 5 minutes), and a difference between the real-time remaining power and the remaining power of the target device when the target charging current starts to be supplied to the target device (that is, the remaining power when the target device is determined to be the target device) is calculated, and the calculated difference is used as the increased power of the target device.
When the increased electric quantity of the target equipment is detected every time, judging whether the increased electric quantity of the target equipment reaches the preset electric quantity, wherein if the increased electric quantity of the target equipment does not reach the preset electric quantity, continuously providing the target charging current output to a charging interface of the host equipment by the power adapter for charging the target equipment, if the increased electric quantity of the target equipment reaches the preset electric quantity, switching to the step of determining the target equipment needing to be charged from the host equipment and the extension equipment, so as to re-determine the target equipment needing to be charged from the host equipment and the extension equipment, thereby charging the re-determined target equipment (specifically, the related description is not repeated), and similarly, when the re-determined increased electric quantity of the target equipment reaches the preset electric quantity, switching to the step of determining the target equipment needing to be charged from the host equipment and the extension equipment again, so as to reciprocate.
It should be noted that, in the embodiment of the present application, the value of the preset electric quantity is not specifically limited, and may be set by a person skilled in the art according to actual needs, for example, the preset electric quantity may be set to 5% of the total electric quantity of the target device, so that when the increased electric quantity of the target device reaches 5% of the total electric quantity of the target device, the target device to be charged is redetermined from the host device and the extension device, and when the increased electric quantity of the redetermined target device reaches 5%, the target device is redetermined from the host device and the extension device again to be charged, and so on.
In one embodiment, the "determining a target device to be charged from the host device and the extension device" includes:
controlling the host equipment to display an equipment selection interface, and receiving an equipment selection instruction input by a user through the equipment selection interface, wherein the equipment selection instruction is used for indicating the host equipment or the extension equipment as target equipment;
and determining the host equipment or the extension equipment indicated by the equipment selection instruction as the target equipment.
In the embodiment of the application, the target device needing to be charged can be determined according to the selection of the user.
For example, referring to fig. 5, the host device is provided with a device selection interface, and when the host device receives a trigger operation of triggering the display device selection interface configured in advance, the host device is controlled to display the device selection interface. The illustrated rectangle represents the extension devices which are identified by the host device and spliced to the host device, and the circular frame in the rectangle represents a "selection" control for selecting the corresponding device, so that the user can click any selection control to select the host device or the extension device corresponding to the selection control (or click the selection control again to cancel the selection of the host device or the extension device corresponding to the selection control). As shown in fig. 5, the device selection interface shows the host device and 3 extension devices (extension device 1, extension device 2, and extension device 3, respectively) spliced to the host device, where extension device 2 has been selected by the user. At this time, the user may click on the "charge" control to input a device selection instruction to the host device for indicating that the extension device 2 in the selected state is determined as the target device that needs to be charged. It is understood that the user may select the host device or the extension device 1 or the extension device 2 as the target device to be charged according to actual needs.
In an embodiment, before "determining a target device that needs to be charged from the host device and the extension device", the method further includes:
