Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
The embodiment of the 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 device', and can also be split to be used separately. It should be noted that the host device is separately provided with a charging interface for connecting an external power source, and the extension device may reuse the charging interface of the host device when being spliced to the host device. In this way, when the host device is connected to the external power supply through the charging interface, the slave device can obtain a charging current from the external power supply through the charging interface of the host device to perform charging, which will be described below.
In addition, wireless communication connection can be established between the host equipment and the extension equipment through respective wireless communication modules, so that data interaction between the host equipment and the extension equipment is carried out based on the wireless communication connection. The Wireless communication module includes, but is not limited to, a Wi-Fi (Wireless Fidelity) module, a bluetooth module, and the like.
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.
Referring to fig. 2 and fig. 2 are schematic flow diagrams of a charging control method according to an embodiment of the present application, where the charging control method according to the embodiment of the present application is applied to a split-type electronic device, the split-type electronic device includes a host device and at least one extension device, and the following description will be made from the perspective of a charging control apparatus, where the flow of the charging control method according to the embodiment of the present application may be as follows:
101. and detecting whether the host equipment is connected with an external power supply through the charging interface.
The host equipment can be connected with the external power supply through the charging interface, so that the external power supply can directly output charging current to the charging interface of the host equipment, and the host equipment is charged or the extension equipment spliced to the host equipment is charged. Correspondingly, in the embodiment of the application, in order to charge the host device or the extension device, whether the host device is connected with an external power supply through a charging interface is firstly detected.
102. And if so, determining target equipment needing to be charged from the host equipment and the extension equipment.
If the host equipment is not connected with the external power supply through the charging interface, whether the host equipment is connected with the external power supply through the charging interface or not is continuously detected until the host equipment is connected with the external power supply through the charging interface. And if the host equipment is detected to be connected with the external power supply through the charging interface, determining target equipment needing to be charged from the host equipment and the extension equipment further 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 filtering rule may be configured to perform filtering according to user selection, referring to fig. 3, the host device is provided with a filtering interface, and when the host device receives a pre-configured trigger operation for triggering the display of the filtering interface, the host device is controlled to display the filtering 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. 3, the screening 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 point, the user may click the "charge" control to input a charge indication to the host device indicating that extension device 2 in the selected state is determined to be the target extension device that needs to be charged.
For another example, the screening rule may be configured to perform screening according to the remaining operating time of the device, wherein the host device may be controlled to send a time length inquiry request to each spliced extension device, where the time length inquiry request is used to inquire the remaining operating time of the extension device. Correspondingly, after receiving the time length inquiry request of the host equipment, the extension equipment predicts the residual running time length of the extension equipment according to the indication of the time length inquiry request and returns the predicted residual running time length to the host equipment. In addition, the host device is also instructed to predict the remaining operating time of the host device, so that after the host device receives the remaining operating time returned by each extension device, the device with the lowest remaining operating time of the host device and the extension devices is further determined as the target device needing to be charged.
103. The host device is controlled to bi-directionally communicate with the external power source to determine a target charging current that needs to be provided by the external power source.
In the embodiment of the application, after the target device needing to be charged is determined from the host device and the extension devices, the host device is controlled to perform bidirectional communication with the external power supply so as to determine the target charging current needing to be provided by the external power supply. How the host device performs bidirectional communication with the external power supply may be performed based on a charging protocol preconfigured by the host device and the external power supply, which is not specifically limited in the embodiment of the present application.
For example, the host device may be controlled to receive a mode inquiry request sent by the external power source through the charging interface, where the mode inquiry request is used to inquire whether to turn on the fast charging mode. Then, identifying whether the determined target equipment supports the rapid charging mode currently according to the mode inquiry request, and if the target equipment supports the rapid charging mode currently, controlling the host equipment to send a mode response message which agrees to start the rapid charging mode to the external power supply so that the external power supply determines the charging current corresponding to the rapid charging mode as the target charging current required to be provided; if the target device is identified not to support the fast charging mode currently (for example, the target device only supports the normal charging mode, or the remaining battery capacity of the target device is too high), the control host device sends a mode response message for refusing to start 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 required to be provided.
It should be noted that the normal charging mode (or standard charging mode) may be understood as a charging mode in which the rated charging voltage is 5V (volt) and the rated charging current is less than 2.5A (ampere). 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.
104. And supplying the target charging current provided by the external power supply to the target device through the charging interface of the host device for charging.
Based on the above description, it can be understood by those skilled in the art that, since the external power source is directly connected to the charging interface of the host device, the target charging current provided by the external power source will be directly output to the charging interface of the host device. Accordingly, after determining that the target charging current required to be supplied by the external power supply is required, the control host device transmits a charging instruction to the external power supply instructing the external power supply to start supplying the target charging current determined before. In addition, a charging loop is established between the target device and the external power supply through the charging interface of the host device, so that the target charging current provided by the external power supply is provided for the target device to be charged through the charging interface of the host device.
For example, assuming that the split type electronic device includes a host device a, an extension device B, and an extension device C, if it is determined that the extension device C is a target device that needs to be charged, a target charging current provided by an external power supply may be provided to the extension device C through a charging interface of the host device a for charging.
By the above, when the split type electronic equipment comprising the host equipment and the at least one extension equipment is charged, whether the host equipment is connected with the external power supply through the charging interface or not can be firstly detected, and if yes, the target equipment needing to be charged is determined from the host equipment and the extension equipment. The host device is then controlled to bi-directionally communicate with the external power source to determine a target charging current that needs to be provided by the external power source. And finally, supplying the target charging current provided by the external power supply to the target device through the charging interface of the host device for charging. Therefore, the user does not need to charge the host equipment and the extension equipment respectively, and the convenience of charging the split type electronic equipment is improved.
Referring to fig. 4, fig. 4 is another schematic flow chart of a charging control method according to an embodiment of the present application, where the flow of the charging control method may be as follows:
201. and detecting whether the host equipment is connected with an external power supply through the charging interface.
The host equipment can be connected with the external power supply through the charging interface, so that the external power supply can directly output charging current to the charging interface of the host equipment, and the host equipment is charged or the extension equipment spliced to the host equipment is charged. Correspondingly, in the embodiment of the application, in order to charge the host device or the extension device, whether the host device is connected with an external power supply through a charging interface is firstly detected.
202. If yes, acquiring the residual electric quantity of the host equipment and acquiring the residual electric quantity of the extension equipment.
203. And determining the device with the lowest residual quantity in the host device and the extension device as the target device needing charging.
In the embodiment of the application, if it is detected that the host device is not connected with the external power supply through the charging interface, whether the host device is connected with the external power supply through the charging interface is continuously detected until it is detected that the host device is connected with the external power supply through the charging interface. And if the host equipment is detected to be connected with the external power supply through the charging interface, determining target equipment needing to be charged from the host equipment and the extension equipment further according to a preset screening rule.
Wherein the screening rule is set as: and taking the device with the lowest residual electric quantity in the host device and the extension devices as a target device needing charging. 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.
204. The host device is controlled to bi-directionally communicate with the external power source to determine a target charging current that needs to be provided by the external power source.
In the embodiment of the application, after the target device needing to be charged is determined from the host device and the extension devices, the host device is controlled to perform bidirectional communication with the external power supply so as to determine the target charging current needing to be provided by the external power supply. How the host device performs bidirectional communication with the external power supply may be performed based on a charging protocol preconfigured by the host device and the external power supply, which is not specifically limited in the embodiment of the present application.
For example, the host device may be controlled to receive a mode inquiry request sent by the external power source through the charging interface, where the mode inquiry request is used to inquire whether to turn on the fast charging mode. Then, identifying whether the determined target equipment supports the rapid charging mode currently according to the mode inquiry request, and if the target equipment supports the rapid charging mode currently, controlling the host equipment to send a mode response message which agrees to start the rapid charging mode to the external power supply so that the external power supply determines the charging current corresponding to the rapid charging mode as the target charging current required to be provided; if the target device is identified not to support the fast charging mode currently (for example, the target device only supports the normal charging mode, or the remaining battery capacity of the target device is too high), the control host device sends a mode response message for refusing to start 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 required to be provided.
It should be noted that the normal charging mode (or standard charging mode) may be understood as a charging mode in which the rated charging voltage is 5V (volt) and the rated charging current is less than 2.5A (ampere). 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.
205. And supplying the target charging current provided by the external power supply to the target device through the charging interface of the host device for charging.
Based on the above description, it can be understood by those skilled in the art that, since the external power source is directly connected to the charging interface of the host device, the target charging current provided by the external power source will be directly output to the charging interface of the host device. Accordingly, after determining that the target charging current required to be supplied by the external power supply is required, the control host device transmits a charging instruction to the external power supply instructing the external power supply to start supplying the target charging current determined before. In addition, a charging loop is established between the target device and the external power supply through the charging interface of the host device, so that the target charging current provided by the external power supply is provided for the target device to be charged through the charging interface of the host device.
For example, assuming that the split type electronic device includes a host device a, an extension device B, and an extension device C, if it is determined that the extension device C is a target device that needs to be charged, a target charging current provided by an external power supply may be provided to the extension device C through a charging interface of the host device a for charging.
206. In the charging process of the target device, the increased electric quantity of the target device is detected.
207. 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 external power supply to the target device for charging, the real-time remaining capacity 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 capacity and the remaining capacity of the target device when the target charging current starts to be supplied to the target device (that is, the remaining capacity when the target device is determined to be the target device) is calculated, and the calculated difference is used as the increased capacity 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 outputting a target charging current output from an external power supply to a charging interface of the host equipment to the target equipment for charging, 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 referring to the related description, which is not repeated here), 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.
