The following description is based on illustrated specific embodiments of the present application and should not be construed as limiting other specific embodiments of the present application not detailed herein.

The embodiment of the present application provides a charging control method, which is applied to a split-type electronic device. As shown in FIG. 1 , the split-type electronic device includes a host device and at least one extension device, and the extension device and the host device can be spliced together to form a "" Complete electronic equipment", which can also be used separately. It should be noted that the host device is separately provided with a charging interface for connecting to an external power source, and the extension device can reuse the charging interface of the host device when splicing to the host device. In this way, when the host device is connected to the external power source through the charging interface, the extension device can obtain charging current from the external power source through the charging interface of the host device for charging, which will be described below.

In addition, a wireless communication connection can be established between the host device and the extension device through respective wireless communication modules, so as to perform data exchange between the two based on the wireless communication connection. The wireless communication module includes, but is not limited to, a Wi-Fi (Wireless Fidelity, wireless fidelity) module, a Bluetooth module, and the like.

For example, the host device can make its own Wi-Fi module work in AP (Access Point, access point) mode, and the extension device can make its own Wi-Fi module work in STA (Station, station) mode, thus, The extension device can establish a Wi-Fi connection with the host device.

It should be noted that the executive 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, wherein the charging control device may adopt a hardware or software manner accomplish.

Please refer to FIG. 2 , which is a schematic flowchart of a charging control method provided by an embodiment of the present application. The charging control method provided by an embodiment of the present application is applied to a split-type electronic device, and the split-type electronic device includes a host device and at least one extension device. , the following will be described from the perspective of a charging control device. The process of the charging control method provided by the embodiment of the present application may be as follows:

101. Detect whether the host device is connected to an external power source through a charging interface.

The host device can be connected to the external power supply through the charging interface, so that the external power supply can directly output the charging current to the charging interface of the host device, thereby charging the host device or charging the extension device spliced to the host device. Correspondingly, in the embodiment of the present application, in order to realize the charging of the host device or the extension device, it is first detected whether the host device is connected to the external power source through the charging interface.

102. If yes, determine the target device that needs to be charged from the host device and the extension device.

Wherein, if it is detected that the host device is not connected to the external power supply through the charging interface, continue to detect whether the host device is connected to the external power supply through the charging interface until it is detected that the host device is connected to the external power supply through the charging interface. If it is detected that the host device is connected to the external power source through the charging interface, the target device that needs to be charged is further determined from the host device and the extension device according to the preset screening rule.

It should be noted that the embodiments of the present application do not impose specific restrictions on the screening rules, which can be set by those skilled in the art according to actual needs.

For example, the filtering rules can be configured to perform filtering according to user selection. Please refer to FIG. 3. The host device provides a filtering interface. When the host device receives a pre-configured trigger operation that triggers the display of the filtering interface, the host device is controlled to display the filtering interface. . Among them, the rectangle in the figure represents the host device and the extension device recognized by the host device and spliced to the host device, and the round box in the rectangle represents the "selection" control used to select the corresponding device, then the user can click any selection control to select the host device or extension device corresponding to the selection control (you can also click the selection control again to deselect the host device or extension device corresponding to the selection control). As shown in Figure 3, the screening interface displays the host device and 3 extension devices (respectively, extension device 1, extension device 2, and extension device 3) spliced to the host device. Among them, extension device 2 has been selected by the user. . At this time, the user can click the "Charge" control to input a charging instruction to the host device, indicating that the extension device 2 in the selected state is determined as the target extension device that needs to be charged.

For another example, the filtering rule can be configured to filter according to the remaining running time of the device, wherein the host device can be controlled to send a duration query request to each extension device that has been spliced, and the duration query request is used to query the remaining running duration of the extension device. Correspondingly, after receiving the duration query request from the host device, the extension device predicts its remaining running duration according to the indication of the duration query request, and returns the predicted remaining running duration to the host device. In addition, it also instructs the host device to predict its own remaining running time, so that after the host device receives the remaining running time returned by each extension device, it further determines the device with the lowest remaining running time among the host device and the extension device as the target that needs to be charged equipment.

103. Control the host device to perform bidirectional communication with the external power supply to determine the target charging current that needs to be provided by the external power supply.

In this embodiment of the present application, after determining the target device to be charged from the host device and the extension device, the host device is controlled to perform bidirectional communication with the external power source to determine the target charging current that needs to be provided by the external power source. Wherein, how the host device performs bidirectional communication with the external power supply may be performed based on a charging protocol preconfigured between the host device and the external power supply, which is not specifically limited in this embodiment of the present application.

Exemplarily, the host device can be controlled to receive a mode inquiry request sent by an external power source through the charging interface, where the mode inquiry request is used to inquire whether to enable the fast charging mode. After that, according to the mode inquiry request, identify whether the determined target device currently supports the fast charging mode. If it is identified that the target device currently supports the fast charging mode, the host device is controlled to send a mode response message that agrees to turn on the fast charging mode to the external power supply, so that The external power supply determines the charging current corresponding to the fast charging mode as the target charging current that needs to be provided; if it is identified that the target device does not currently support the fast charging mode (for example, the target device only supports the normal charging mode, or the remaining battery power of the target device is too high) , the host device is controlled to send a mode response message of refusing to turn on the fast charging mode to the external power supply, so that the external power supply determines the charging current corresponding to the normal charging mode as the target charging current that needs to be provided.

It should be noted that the normal charging mode (or the standard charging mode) can be understood as a charging mode in which the rated charging voltage is 5V (volts) and the rated charging current is less than 2.5A (amperes). The charging speed of the fast charging mode (or direct charging mode) is higher than that of the ordinary 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.

104. Provide the target charging current provided by the external power source to the target device for charging through the charging interface of the host device.

Based on the above description, those skilled in the art can understand that, since the external power supply is directly connected to the charging interface of the host device, the target charging current provided by the external power supply will be directly output to the charging interface of the host device. Correspondingly, after determining the target charging current that needs to be provided by the external power source, the control host device sends a charging instruction to the external power source, instructing the external power source to start providing the previously determined target charging current. In addition, a charging loop is established between the target device and the external power source through the charging interface of the host device, so that the target charging current provided by the external power source is provided to the target device for charging through the charging interface of the host device.

For example, assuming that the split-type electronic device includes host device A, extension device B, and extension device C, if it is determined that extension device C is the target device that needs to be charged, the target charging current provided by the external power supply can be provided through the charging interface of host device A to the device. Extension device C is charged.

It can be seen from the above that when charging a split electronic device including a host device and at least one extension device in this embodiment of the present application, it can first detect whether the host device is connected to an external power supply through a charging interface, and if so, the host device and the extension device are Identify the target device that needs to be charged. The control host device then communicates bidirectionally with the external power supply to determine the target charging current that needs to be provided by the external power supply. Finally, the target charging current provided by the external power supply is provided to the target device for charging through the charging interface of the host device. Therefore, the user does not need to charge the host device and the extension device separately, which improves the convenience of charging the split-type electronic device.

Please refer to FIG. 4 , which is another schematic flowchart of a charging control method provided by an embodiment of the present application. The process of the charging control method may be as follows:

201. Detect whether the host device is connected to an external power source through a charging interface.

The host device can be connected to the external power supply through the charging interface, so that the external power supply can directly output the charging current to the charging interface of the host device, thereby charging the host device or charging the extension device spliced to the host device. Correspondingly, in the embodiment of the present application, in order to realize the charging of the host device or the extension device, it is first detected whether the host device is connected to the external power source through the charging interface.

202. If yes, obtain the remaining power of the host device and obtain the remaining power of the extension device.

203. Determine the device with the lowest remaining power among the host device and the extension device as the target device that needs to be charged.

In the embodiment of the present application, if it is detected that the host device is not connected to the external power supply through the charging interface, it continues to detect whether the host device is connected to the external power supply through the charging interface until it is detected that the host device is connected to the external power supply through the charging interface. If it is detected that the host device is connected to the external power source through the charging interface, the target device that needs to be charged is further determined from the host device and the extension device according to the preset screening rule.

The filtering rule is set as follows: the device with the lowest remaining power among the host device and the extension device is used as the target device that needs to be charged. Therefore, in order to determine the target device to be charged, it is necessary to obtain the remaining power of the host device and the remaining power of the extension device first. It should be noted that the remaining power of the host device refers to the remaining power of the battery in the host device, and the remaining power of the extension device refers to the remaining power of the battery in the extension device.

In order to obtain the remaining power of the host device and the extension device, a fuel gauge is built in the host device and the extension device respectively, and the fuel gauge is used to estimate the remaining power of the battery in the device where they are located.

The fuel gauge can use the open-circuit voltage method, the battery modeling method, or the coulomb measurement method to estimate the remaining power of the battery in the device where it is located. In addition, other methods not listed in the embodiments of the present application can also be used to estimate the remaining power of the battery. , which is not specifically limited in the embodiments of the present application.

For example, when using the battery modeling method, it is necessary to establish a comparison table of voltage and remaining power in advance according to the discharge curve of the battery, and the comparison table describes the corresponding relationship between the voltage of the battery and its remaining power. Correspondingly, when the remaining power of the battery needs to be estimated, the voltage of the battery is first measured, and then the remaining power corresponding to the voltage is queried in the comparison table.

Correspondingly, when acquiring the remaining power of the host device, the remaining power estimated by the built-in power meter of the host device can be directly read. When obtaining the remaining power of the extension device, the host device can be controlled to send a power acquisition request to the extension device through the wireless communication connection established between it and the extension device, and instruct the extension device to return its remaining power. On the other hand, when the extension device receives a power acquisition request from the host device, it reads the remaining power estimated by its built-in power meter, and transmits the read remaining power through wireless communication with the host device. The connection is returned to the host device. Thereby, the remaining power of each extension device can be obtained.

After obtaining the remaining power of the host device and the remaining power of the extension device, further determine the device with the lowest remaining power from the host device and the extension device, and determine the device with the lowest remaining power as the target device that needs to be charged .

For example, assuming that the split electronic device includes host device A, extension device B and extension device C, use a to represent the remaining power of host device A, b to represent the remaining power of extension device B, and c to represent the remaining power of 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 can be determined as the target device that needs to be charged.

204. Control the host device to perform bidirectional communication with the external power source to determine a target charging current that needs to be provided by the external power source.

In this embodiment of the present application, after determining the target device to be charged from the host device and the extension device, the host device is controlled to perform bidirectional communication with the external power source to determine the target charging current that needs to be provided by the external power source. Wherein, how the host device performs bidirectional communication with the external power supply may be performed based on a charging protocol preconfigured between the host device and the external power supply, which is not specifically limited in this embodiment of the present application.

Exemplarily, the host device can be controlled to receive a mode inquiry request sent by an external power source through the charging interface, where the mode inquiry request is used to inquire whether to enable the fast charging mode. After that, according to the mode inquiry request, identify whether the determined target device currently supports the fast charging mode. If it is identified that the target device currently supports the fast charging mode, the host device is controlled to send a mode response message that agrees to turn on the fast charging mode to the external power supply, so that The external power supply determines the charging current corresponding to the fast charging mode as the target charging current that needs to be provided; if it is identified that the target device does not currently support the fast charging mode (for example, the target device only supports the normal charging mode, or the remaining battery power of the target device is too high) , the host device is controlled to send a mode response message of refusing to turn on the fast charging mode to the external power supply, so that the external power supply determines the charging current corresponding to the normal charging mode as the target charging current that needs to be provided.

It should be noted that the normal charging mode (or the standard charging mode) can be understood as a charging mode in which the rated charging voltage is 5V (volts) and the rated charging current is less than 2.5A (amperes). The charging speed of the fast charging mode (or direct charging mode) is higher than that of the ordinary 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.

205. Provide the target charging current provided by the external power source to the target device for charging through the charging interface of the host device.

Based on the above description, those skilled in the art can understand that, since the external power supply is directly connected to the charging interface of the host device, the target charging current provided by the external power supply will be directly output to the charging interface of the host device. Correspondingly, after determining the target charging current that needs to be provided by the external power source, the control host device sends a charging instruction to the external power source, instructing the external power source to start providing the previously determined target charging current. In addition, a charging loop is established between the target device and the external power source through the charging interface of the host device, so that the target charging current provided by the external power source is provided to the target device for charging through the charging interface of the host device.

For example, assuming that the split-type electronic device includes host device A, extension device B, and extension device C, if it is determined that extension device C is the target device that needs to be charged, the target charging current provided by the external power supply can be provided through the charging interface of host device A to the device. Extension device C is charged.

206. During the charging process of the target device, detect the increased power of the target device.

207. If it is detected that the increased power of the target device reaches the preset power level, re-determine the target device that needs to be charged from the host device and the extension device.

In the process of supplying the target charging current provided by the external power source to the target device for charging, a preset detection period (which can be selected by a person of ordinary skill in the art to an appropriate value according to actual needs, for example, the detection period can be configured as 5 minutes), obtain the real-time remaining power of the target device, and calculate the difference between the real-time remaining power and the remaining power of the target device when it starts to provide the target charging current to the target device (that is, the remaining power when the target device is determined as the target device). Difference, take the calculated difference as the added power of the target device.

Each time the increased power of the target device is detected, it is determined whether the increased power of the target device has reached the preset power, wherein, if the increased power of the target device does not reach the preset power, the external power supply will continue to be output to the host device for charging The target charging current of the interface is provided to the target device for charging. If the increased power of the target device reaches the preset power level, then go to the step of “determining the target device that needs to be charged from the host device and the extension device” to obtain the target device from the host device. and the extension device to re-determine the target device that needs to be charged, so as to charge the re-determined target device (for details, please refer to the relevant description above, which will not be repeated here). Similarly, in the increase of the re-determined target device When the power reaches the preset power level, the process of “determining the target device that needs to be charged from the host device and the extension device” is performed again, and so on.

It should be noted that the embodiments of the present application do not impose specific restrictions on the value of the preset power, which can be set by those of ordinary skill in the art according to actual needs. For example, the preset power may be set to 5% of the total power of the target device. In this way, when the increased power of the target device reaches 5% of its total power, the target device that needs to be charged will be re-determined from the host device and the extension device, and when the increased power of the re-determined target device reaches 5%, Re-determine the target device from the host device and the extension device for charging again, and so on.
