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 (not shown in fig. 1) for connecting an external power supply, and the slave device is not separately provided with a charging interface. The host device may obtain the charging current from the external power source to charge the battery of the host device when the external power source is connected, and the extension device may obtain the charging current from the battery of the host device to charge the battery of the extension device when the extension device is spliced with the host device, as 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, fig. 2 is a schematic flow chart of a charging control method according to an embodiment of the present disclosure. The charging control method provided by the embodiment of the present application is applied to a split type electronic device, where the split type electronic device includes a host device and at least one extension device, and will be described below from the perspective of a charging control apparatus, a flow of the charging control method provided by the embodiment of the present application may be as follows:
101. and detecting whether the host equipment of the split type electronic equipment is connected with an external power supply through the charging interface.
It should be noted that, in the embodiment of the present application, the charging interface included in the host device may be a wired charging interface, and may also be a wireless charging interface. The physical representation form of the wired 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. The physical representation of the wireless charging interface may be a charging coil, and it should be understood that the charging coil includes, but is not limited to, a circular charging coil, an elliptical charging coil, and the like.
When detecting whether the host device is connected with an external power supply through the charging interface, it may be detected whether the host device is connected with an external wired power supply through the wired charging interface (e.g., a wired charger), or whether the host device is connected with an external wireless power supply through the wireless charging interface (e.g., a wireless charging base).
102. And if so, acquiring a first charging current from an external power supply through a charging interface of the host equipment to charge the battery of the host 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, controlling the host equipment to carry out two-way communication with the external power supply, so that the external power supply determines the charging current required to be output to the charging interface. It should be noted that how the host device performs bidirectional communication with the external power supply may be performed based on a charging protocol pre-configured for 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, whether the host equipment supports the quick charging mode currently is identified according to the mode inquiry request, if the host equipment supports the quick charging mode currently, the host equipment is controlled to send mode response information which agrees to start the quick charging mode to an external power supply, and the external power supply determines the charging current corresponding to the quick charging mode as the charging current which needs to be output to a charging interface; if the host device is identified not to support the fast charging mode currently (for example, the host device only supports the normal charging mode, or the battery residual capacity of the host device is too high), the host device is controlled to send 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 charging current required to be output to the charging interface.
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.
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 charging current output by the external power source will be directly output to the charging interface of the host device. Therefore, after the host device is connected with the external power supply through the charging interface and the external power supply determines the charging current required to be output to the charging interface, the charging current output by the external power supply can be acquired through the charging interface of the host device, the charging current is recorded as a first charging current, and the battery of the host device is charged by using the first charging current.
103. The method comprises the steps of determining target extension equipment needing to be charged from at least one extension equipment included in the split type electronic equipment, and determining second charging current provided for the target extension equipment to be charged by a battery of the host equipment, wherein the second charging current is smaller than the first charging current.
The target extension set equipment needing to be charged can be determined from at least one extension set equipment included in the split type electronic equipment according to a preset extension set screening rule. The extension screening rules in the embodiment of the present application are not specifically limited, and may be configured by those skilled in the art according to actual needs.
For example, the extension screening rule may be configured to perform screening according to user selection, referring to fig. 3, the host device is provided with an extension screening interface, and the host device may be controlled to display the extension screening interface when the host device receives a pre-configured trigger operation for triggering display of the extension screening interface. The graphic rectangle represents the extension devices which are identified by the host device and spliced to the host device, the circular frame in the rectangle represents a selection control for selecting the corresponding extension device, and if the user needs to charge a certain extension device by the host device, the user can click the selection control corresponding to the extension device to select the extension device (or click the selection control corresponding to the extension device again to cancel the selection of the extension device). As shown in fig. 3, the host device has spliced 4 extension devices, namely, extension device 1, extension device 2, extension device 3, and extension device 4, and extension device 2 has been selected by the user. At this time, the user may click the "charge" control to input a charge instruction to the host device, instructing the host device to determine the extension device 2 in the selected state as the target extension device that needs to be charged.
For another example, the extension screening rule may be configured to perform screening according to the remaining operating time lengths of the extension devices, wherein the host device may be controlled to send a time length inquiry request to each extension device that has been spliced, where the time length inquiry request is used to inquire the remaining operating time lengths of the extension devices. 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. After the host device receives the remaining running time returned by each extension device, the extension device with the lowest remaining running time is further determined as the target extension device needing to be charged.
After the target extension device needing to be charged is determined from the extension devices, the charging current provided by the battery of the host device to the target extension device for charging is further determined, and the charging current is recorded as a second charging current. It should be noted that, in order to ensure charging of the host device, the second charging current provided to the target extension device should be smaller than the first charging current that can be acquired through the charging interface of the host device, and as a constraint, a person skilled in the art may determine the second charging current provided by the host battery to the target extension device for charging according to actual needs.
For example, the second charging current may be configured to be a preset percentage of the first charging current, and if the preset percentage is configured to be 80%, if the first charging current is 2.5A, it may be determined that the second charging current provided by the battery of the host device is 2.5 × 80% — 2 (a).
For another example, the second charging current may be configured according to a user input, and the range of the second charging current that the user may input may be limited to be smaller than the external charging current.
104. And controlling the battery of the host device to provide a second charging current to charge the battery of the target extension device.
In the embodiment of the application, after the target extension device needing to be charged is determined from the extension devices, and the second charging current provided by the battery of the host device to the target extension device for charging is determined, during the period of acquiring the first charging current to charge the battery of the host device, the battery of the host device is controlled to provide the second charging current to charge the battery of the target extension device. Thus, the battery of the extension device can be charged by the battery of the host device while the battery of the host device is charged by the external power supply.
For example, if the external power source determines that the first charging current required to be output to the charging interface of the host device is 3A, and determines that the second charging current provided by the battery of the host device to the target extension device for charging is 1.5A, the battery of the host device is further controlled to provide the second charging current of 1.5A to charge the battery of the target extension device while acquiring the first charging current of 3A from the external power source to charge the battery of the host device.
Therefore, when the split type electronic equipment comprising the host equipment and the at least one extension equipment is charged, whether the host equipment of the split type electronic equipment is connected with the external power supply through the charging interface can be firstly detected, if so, the first charging current is acquired from the external power supply through the charging interface of the host equipment to charge the battery of the host equipment. In addition, a target extension device needing to be charged is determined from at least one extension device included in the split type electronic device, and a second charging current provided by the battery of the host device for charging the target extension device is determined. And finally, controlling the battery of the host device to provide a second charging current to charge the battery of the target extension device. 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 of the split type electronic equipment is connected with an external power supply through the charging interface.
It should be noted that, in the embodiment of the present application, the charging interface included in the host device may be a wired charging interface, and may also be a wireless charging interface.
The physical representation form of the wired 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. The physical representation of the wireless charging interface may be a charging coil, and it should be understood that the charging coil includes, but is not limited to, a circular charging coil, an elliptical charging coil, and the like.
When detecting whether the host device is connected with an external power supply through the charging interface, it may be detected whether the host device is connected with an external wired power supply through the wired charging interface (e.g., a wired charger), or whether the host device is connected with an external wireless power supply through the wireless charging interface (e.g., a wireless charging base).
202. And if so, acquiring a first charging current from an external power supply through a charging interface of the host equipment to charge the battery of the host 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, controlling the host equipment to carry out two-way communication with the external power supply, so that the external power supply determines the charging current required to be output to the charging interface. It should be noted that how the host device performs bidirectional communication with the external power supply may be performed based on a charging protocol pre-configured for 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, whether the host equipment supports the quick charging mode currently is identified according to the mode inquiry request, if the host equipment supports the quick charging mode currently, the host equipment is controlled to send mode response information which agrees to start the quick charging mode to an external power supply, and the external power supply determines the charging current corresponding to the quick charging mode as the charging current which needs to be output to a charging interface; if the host device is identified not to support the fast charging mode currently (for example, the host device only supports the normal charging mode, or the battery residual capacity of the host device is too high), the host device is controlled to send 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 charging current required to be output to the charging interface.
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.
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 charging current output by the external power source will be directly output to the charging interface of the host device. Therefore, after the host device is connected with the external power supply through the charging interface and the external power supply determines the charging current required to be output to the charging interface, the charging current output by the external power supply can be acquired through the charging interface of the host device, the charging current is recorded as a first charging current, and the battery of the host device is charged by using the first charging current.
203. And acquiring the residual electric quantity of the battery of each extension device in the split type electronic device.
In the embodiment of the application, the host device determines the target extension device to be charged according to the residual capacity of the battery of the extension device. In order to acquire the remaining capacity of the battery of the extension equipment, an electricity meter can be built in the extension equipment, so that the remaining capacity of the battery of the extension equipment is acquired through the electricity meter in the extension equipment.
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.
Correspondingly, when the residual electric quantity of the battery 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 remaining capacity of the battery of each slave unit device can be acquired.
204. And determining the extension set equipment with the lowest residual quantity of the battery as the target extension set equipment needing charging.
In the embodiment of the application, after the residual electric quantity of the battery of each extension device is obtained, the extension device with the lowest residual electric quantity of the battery is further determined, and the extension device with the lowest residual electric quantity of the battery is determined as the target extension device needing to be charged.
For example, assuming that the split-type electronic device includes a host device a, an extension device B, an extension device C, and an extension device D, B represents the remaining capacity of the battery of the extension device B, C represents the remaining capacity of the battery of the extension device C, and D represents the remaining capacity of the battery of the extension device D, and B > C > D, that is, the extension device D is the extension device with the lowest remaining capacity of the batteries in the extension device B, the extension device C, and the extension device D, at this time, the extension device D may be determined as the target extension device that needs to be charged.
205. Determining a second charging current provided by the battery of the host device to the target extension device for charging, wherein the second charging current is less than the first charging current.
After the target extension device needing to be charged is determined from the extension devices, the charging current provided by the battery of the host device to the target extension device for charging is further determined, and the charging current is recorded as a second charging current. It should be noted that, in order to ensure charging of the host device, the second charging current provided to the target extension device should be smaller than the first charging current that can be acquired through the charging interface of the host device, and as a constraint, a person skilled in the art may determine the second charging current provided by the host battery to the target extension device for charging according to actual needs.
For example, the second charging current may be configured to be a preset percentage of the first charging current, and if the preset percentage is configured to be 80%, if the first charging current is 2.5A, it may be determined that the second charging current provided by the battery of the host device is 2.5 × 80% — 2 (a).
For another example, the second charging current may be configured according to a user input, and the range of the second charging current that the user may input may be limited to be smaller than the external charging current.
206. And controlling the battery of the host device to provide a second charging current to charge the battery of the target extension device.
In the embodiment of the application, after the target extension device needing to be charged is determined from the extension devices, and the second charging current provided by the battery of the host device to the target extension device for charging is determined, during the period of acquiring the first charging current to charge the battery of the host device, the battery of the host device is controlled to provide the second charging current to charge the battery of the target extension device. Thus, the battery of the extension device can be charged by the battery of the host device while the battery of the host device is charged by the external power supply.
For example, if the external power source determines that the first charging current required to be output to the charging interface of the host device is 3A, and determines that the second charging current provided by the battery of the host device to the target extension device for charging is 1.5A, the battery of the host device is further controlled to provide the second charging current of 1.5A to charge the battery of the target extension device while acquiring the first charging current of 3A from the external power source to charge the battery of the host device.
207. And in the charging process of the target extension equipment, detecting the increased electric quantity of the battery of the target extension equipment.
208. And if the increased electric quantity of the target extension equipment reaches the preset electric quantity, determining the target extension equipment needing to be charged again from at least one extension equipment included in the split type electronic equipment.
In the process of charging the battery of the target extension apparatus by providing the second charging current by the battery of the host apparatus, the real-time remaining power of the battery of the target extension apparatus 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), the difference between the real-time remaining power and the remaining power of the battery of the target extension apparatus when the second charging current starts to be provided to the target extension apparatus (that is, the remaining power when the target extension apparatus is determined to be the target extension apparatus) is calculated, and the calculated difference is used as the increased power of the battery of the target extension apparatus.
When the increased electric quantity of the target extension equipment is detected each time, judging whether the increased electric quantity of the target extension equipment reaches the preset electric quantity, wherein if the increased electric quantity of the battery of the target extension equipment does not reach the preset electric quantity, continuously providing a second charging current by the battery of the host equipment to charge the target extension equipment, if the increased electric quantity of the battery of the target extension equipment reaches the preset electric quantity, switching to the step of determining the target extension equipment needing to be charged from at least one extension equipment included in the split type electronic equipment, so as to re-determine the target extension equipment needing to be charged from the extension equipment, thereby charging the re-determined target extension equipment (specifically please refer to the related description above, which is not repeated here), and similarly, when the re-determined increased electric quantity of the battery of the target extension equipment reaches the preset electric quantity, and the step of determining the target extension set equipment needing to be charged from at least one extension set equipment included in the split type electronic equipment is carried out again, and the steps are repeated.
It should be noted that, the value of the preset electric quantity is not specifically limited in the embodiment of the present application, 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 extension apparatus, so that, when the battery of the host apparatus charges the battery of the target extension apparatus and the increased electric quantity of the battery of the target extension apparatus reaches 5% of the total electric quantity, the target extension apparatus that needs to be charged is determined again from the extension apparatus, and when the battery of the host apparatus charges the battery of the determined target extension apparatus and the increased electric quantity of the battery reaches 5%, the target extension apparatus is determined again from the extension apparatus for charging, and so on.
In one embodiment, "controlling the battery of the host device to provide the second charging current to charge the battery of the target extension device" includes:
and controlling the battery of the host device to provide a second charging current for the power management chip of the target extension device, so that the power management chip of the target extension device charges the battery of the target extension device.
For example, referring to fig. 5, in the charging scenario shown in fig. 5, the host device includes a charging switch (for example, it can be implemented by MOS transistors connected back to back), a charging interface, and a battery, and the slave device includes a power management chip, a boost module, and a battery. On one hand, when the host device is detected to be connected with the external power supply through the charging interface, the external power supply is indicated to start providing the first charging current, the first charging current is acquired from the external power supply through the charging interface of the host device, and the first charging current is directly charged for the battery of the host device after passing through the charging switch of the host device.
