[0020] In order to make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be further elaborated in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be construed as limitations on the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0021] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0022] The terms "first / second / third" involved are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein are for the purpose of describing this application only and are not intended to limit this application.

[0024] In the related art, a solar notebook includes a solar panel and a battery, and the solar panel can only charge the battery when the solar notebook is not started. That is, when the user is using the solar notebook, the solar panel cannot charge the battery or supply power to the system of the solar notebook. Therefore, in the related art, solar charging and user use of the system cannot exist simultaneously, and the utilization of solar energy is not sufficient.

[0025] To solve the technical problem of insufficient utilization of solar energy in the related art, an embodiment of this application provides an electronic device. Exemplarily, the electronic device includes but is not limited to a smart phone, a tablet computer, a wearable device, a personal computer (PC), a netbook, etc., and the implementation form of this application is not fixedly limited.

[0026] Figure 1 Schematic diagram of the composition structure of an electronic device provided by an embodiment of this application Figure 1 , such as Figure 1 shown, the electronic device 100 includes: a photovoltaic module 110, an electronic component 120, a power interface 130, a switch component 140, and a controller (not shown in the figure); the electronic component 120 is a component that operates by being powered by a power source other than the electronic component 120; the power interface 130 is connected to the electronic component 120 through the switch component 140; wherein,

[0027] The power interface 130 is used to connect to an external power source (not shown in the figure);

[0028] The controller is used to control at least one of the photovoltaic module 110 and the external power source to supply power to the electronic component 100 through the switch component 140 according to the electric energy provided by the photovoltaic module 110 and the connection situation between the power interface 130 and the external power source.

[0029] In the embodiments of the present application, the electronic device further includes a collection unit that can collect the electrical energy generated by the photovoltaic module and send the collected electrical energy to the controller. The controller can determine whether the photovoltaic module starts to convert solar energy into electrical energy based on the collected electrical energy. Exemplarily, the collection unit may include at least one of the following: a current collection unit, a voltage collection unit, and a power collection unit. Correspondingly, the electrical energy may include at least one of the following: the current provided by the photovoltaic module, the voltage provided by the photovoltaic module, and the power provided by the photovoltaic module. The controller may be an Embedded Controller (EC).

[0030] In the embodiments of the present application, the connection status between the power interface and the external power supply can indicate whether the power interface is connected to the external power supply. In some embodiments, the electronic device is provided with an interface sensing unit that can monitor in real time whether the power interface is connected to the device and determine the type of the device when the power interface is connected to the device. The interface sensing unit can send the connection status between the power interface and the external power supply to the controller. Exemplarily, the interface sensing unit may be a PD (Power Delivery) module.

[0031] In the embodiments of the present application, the photovoltaic module is connected to the electronic component. That is, the on and off of the switch component in the electronic device will not affect the power supply of the photovoltaic module to the electronic component. In this way, when the electronic component needs to work, the electrical energy generated by the photovoltaic module can be used to supply power to the electronic component, thereby improving the utilization rate of solar energy. Among them, the above-mentioned electronic component is a component that is powered by a power supply other than the electronic component to work. That is to say, the electronic component itself does not have a power supply and needs to be powered by a power supply other than the electronic component (such as the energy storage module in the electronic device, the working photovoltaic module, and the external power supply). Exemplarily, the electronic component may be a Central Processing Unit (CPU), and may also be components such as a Graphics Processing Unit (GPU), an SSD, a memory, a network card, and a display screen.

[0032] In some embodiments, the switch component is provided with a control port, and the controller is connected to the control port of the switch component; the controller can generate a control signal for conduction or disconnection based on the electrical energy provided by the photovoltaic module and the connection status between the power interface and the external power supply, and send the generated control signal to the control port of the switch component to achieve the conduction or disconnection of the switch component.

[0033] In the embodiments of the present application, the controller can determine whether the photovoltaic module starts photovoltaic conversion based on the electrical energy provided by the photovoltaic module, and determine whether an external power source is connected to the electronic device based on the connection status of the power interface with the external power source. In this way, when the photovoltaic module is working and no external power source is connected, the controller can control the photovoltaic module to supply power to the electronic components through the switching component; or when the photovoltaic module is not working and an external power source is connected, the controller can control the external power source to supply power to the electronic components through the switching component; or when the photovoltaic module is working and an external power source is connected, the controller can control the photovoltaic module and the external power source to supply power to the electronic components through the switching component. Thus, when the electronic device is turned on, the photovoltaic module can also power the working electronic components, thereby improving the utilization rate of solar energy.

[0034] In some embodiments, when the connection status indicates that the power interface is connected to an external power source and the photovoltaic module can generate electrical energy, the switching component is closed so that the photovoltaic module and the external power source jointly supply power to the electronic components.

[0035] As Figure 1 shown, when the photovoltaic module 110 generates electrical energy, the photovoltaic module can supply power to the electronic components. When the power interface 130 is connected to an external power source, the controller can control the switching component 140 to close, so that the external power source can supply power to the electronic components.

[0036] In some embodiments, as Figure 2 shown, the electronic device 100 further includes an energy storage module 150; one end of the photovoltaic module 110 connected to the electronic components 120 is connected to the energy storage module 150 through the switching component 140; the power interface 130 is respectively connected to the energy storage module 150 and the electronic components 120 through the switching component 140; wherein,

[0037] the controller is configured to control at least one of the photovoltaic module 110, the energy storage module 150, and the external power source to supply power to the electronic components 120 through the switching component 140 according to the electrical energy provided by the photovoltaic module and the connection status of the power interface with the external power source, and / or control at least one of the photovoltaic module 110 and the external power source to charge the energy storage module 150 through the switching component 140 according to the electrical energy provided by the photovoltaic module and the connection status of the power interface with the external power source.

[0038] In some embodiments, for the case where the photovoltaic module generates electrical energy and the connection indicates that the power supply interface is not connected to an external power supply: When the electronic component starts to work, the electronic component reduces the system voltage of the electronic device. At this time, the voltage corresponding to the photovoltaic module is greater than the system voltage. Therefore, the photovoltaic module supplies power to the electronic component. When the power supply provided by the photovoltaic module can meet the requirements of the electronic component, the system voltage remains unchanged. At this time, the switch module can be in a closed state. Because the output voltage of the photovoltaic module is greater than the voltage of the energy storage module, the photovoltaic module can charge the energy storage module. When the power supply provided by the photovoltaic module cannot meet the requirements of the electronic component, the system voltage continues to drop. At this time, the photovoltaic module actively reduces its own output voltage until the output voltage of the photovoltaic module is equal to the voltage of the energy storage module. Because the electronic component is in a working state, it continuously increases the power demand, resulting in a continuous drop in the system voltage until the system voltage is less than the voltage of the energy storage module. At this time, the energy storage module supplies power to the electronic component. Among them, in the case where the photovoltaic module generates electrical energy and the connection indicates that the power supply interface is not connected to an external power supply, the controller can close the switch component.

[0039] As can be seen from the above, when the photovoltaic module generates electrical energy and the connection indicates that the power supply interface is not connected to an external power supply, the photovoltaic module can preferentially supply power to the electronic component. When the photovoltaic module can meet the power requirements of the electronic component, the photovoltaic module can also charge the energy storage module. When the photovoltaic module cannot meet the power requirements of the electronic component, the energy storage module can supply power to the electronic component. In this way, the utilization rate of solar energy can be further improved.

[0040] In some embodiments, for the case where the photovoltaic module generates electrical energy and the connection indicates that the power supply interface is connected to an external power supply: The controller can control the external power supply to charge the energy storage module and control the photovoltaic module to supply power to the electronic component through the switch module. When the power supply provided by the photovoltaic module cannot meet the requirements of the electronic component, the system voltage continues to drop. At this time, the controller can control the external power supply to supply power to the electronic component through the switch module. It can be understood that because the system voltage continues to drop, when the system voltage is less than the output voltage of the external power supply, the charging path from the external power supply to the energy storage module will be shunted by the lower system voltage, so that a part of the charging power is compensated to the electronic component, and the remaining part is used for charging the energy storage module. When the required power of the electronic component further increases, it will cause the system voltage to continue to decrease until the charging power provided by the external power supply is completely compensated to the electronic component, the energy storage module stops charging, and the energy storage module will be affected by the lower system voltage and discharge to the system. In this way, it is possible to realize that the photovoltaic module, the energy storage module, and the external power supply jointly supply power to the electronic component.

[0041] As can be seen from the above, when the photovoltaic module generates electrical energy and the connection indicates that the power supply interface is connected to an external power supply, by controlling the switch module, the photovoltaic module can supply power to the electronic component, and the external power supply can charge the energy storage module; the photovoltaic module and the external power supply can supply power to the electronic component, and the external power supply can charge the energy storage module; the photovoltaic module, the energy storage module and the external power supply can jointly supply power to the electronic component. Thus, the flexibility of power supply of the photovoltaic module, the energy storage module and the external power supply is improved.

[0042] In some embodiments, as Figure 3 shown, the switch assembly includes a first switch module 1401 and a second switch module 1402; the power supply interface 130 is connected to the first end of the first switch module 1401; the second end of the first switch module 1401 is respectively connected to the energy storage module 150 and the first end of the second switch module 1402; the second end of the second switch module 1402 is respectively connected to the photovoltaic module 110 and the electronic component 120.

[0043] In the embodiment of the present application, the controller is configured to close the second switch module and open the first switch module when the connection indicates that the power supply interface is not connected to an external power supply and the photovoltaic module generates electrical energy, so that the photovoltaic module supplies power to the electronic component, or so that the photovoltaic module supplies power to the electronic component and charges the energy storage module.

[0044] It can be understood that when the connection indicates that the power supply interface is not connected to an external power supply and the photovoltaic module generates electrical energy, the electronic component that starts to work will reduce the system voltage of the electronic device. At this time, the output voltage of the photovoltaic module is greater than the system voltage, so the photovoltaic module will supply power to the electronic component. When the power supplied by the photovoltaic module can meet the requirements of the electronic component, the system voltage will remain unchanged. At this time, the second switch module is in the closed state. Because the output voltage of the photovoltaic module is greater than the voltage of the energy storage module, the photovoltaic module can charge the energy storage module. When the power supplied by the photovoltaic module cannot meet the requirements of the electronic component, the system voltage will continue to drop. At this time, the photovoltaic module will actively reduce its own output voltage until the output voltage of the photovoltaic module is equal to the voltage of the energy storage module. Because the electronic component is in the working state, it will continuously increase the power demand, resulting in a continuous drop in the system voltage until the system voltage is less than the voltage of the energy storage module. At this time, the energy storage module supplies power to the electronic component.

[0045] In the embodiment of the present application, the controller can obtain the voltage of the energy storage module, and then set the output voltage of the photovoltaic module according to the voltage of the energy storage module, where the output voltage of the photovoltaic module is greater than the voltage of the energy storage module.

[0046] In the embodiments of the present application, when the connection situation indicates that the power supply interface is connected to an external power supply and the photovoltaic module generates electrical energy, the second switch module and the first switch module are closed, so that the external power supply and the photovoltaic module perform one of the following:

[0047] The external power supply charges the energy storage module, and the photovoltaic module supplies power to the electronic components;

[0048] The external power supply charges the energy storage module, and the photovoltaic module and the external power supply jointly supply power to the electronic components;

[0049] The photovoltaic module, the external power supply, and the energy storage module jointly supply power to the electronic components.

[0050] In the embodiments of the present application, during the process of the photovoltaic module supplying power to the electronic components, when the system voltage of the electronic device can remain unchanged, the controller can disconnect the second switch module to prohibit the photovoltaic module from charging the energy storage module during the process of the external power supply charging the energy storage module. At this time, the external power supply charges the energy storage module, and the photovoltaic module supplies power to the electronic components.

[0051] In some embodiments, during the process of the photovoltaic module supplying power to the electronic components, when the system voltage of the electronic device decreases, the controller can close the second switch module so that the external power supply supplies power to the electronic components. It can be understood that because the system voltage will continue to drop, when the system voltage is less than the output voltage of the external power supply, the charging path from the external power supply to the energy storage module will be shunted by the lower system voltage, so that a part of the charging power is compensated to the electronic components, and the remaining part is used for charging the energy storage module. At this time, the external power supply charges the energy storage module, and the photovoltaic module and the external power supply jointly supply power to the electronic components.

[0052] When the required power of the electronic components further increases, it will cause the system voltage to continue to drop until the charging power provided by the external power supply is completely compensated to the electronic components, the energy storage module stops charging, and the energy storage module will be affected by the lower system voltage and discharge to the system. At this time, the photovoltaic module, the external power supply, and the energy storage module jointly supply power to the electronic components.

[0053] In some embodiments, as Figure 4 shown, the electronic device 100 further includes a third switch module 160; the power supply interface 130 is connected to the electronic components 120 through the third switch module 160; wherein, the controller is used for:

[0054] When the power supply interface is not connected to an external power supply and the photovoltaic module does not generate current, disconnect the second switch module, and close the first switch module and the third switch module, so that the energy storage module supplies power to the electronic components;

[0055] When the power supply interface is not connected to an external power supply and the photovoltaic module generates current, disconnect the first switch module and the third switch module, and close the second switch module;

[0056] When the power supply interface is connected to an external power supply and the photovoltaic module does not generate current, disconnect the second switch module, and close the first switch module and the third switch module, so that the external power supply supplies power to the electronic components and charges the energy storage module;

[0057] When the power supply interface is connected to an external power supply and the photovoltaic module generates current, disconnect the third switch module, and close the first switch module and the second switch module, or disconnect the third switch module and the second switch module, and close the first switch module.

[0058] It can be understood that when the power supply interface is not connected to an external power supply and the photovoltaic module does not generate current, the energy storage module can supply power to the electronic components through the first switch module and the third switch module path.

[0059] When the power supply interface is not connected to an external power supply and the photovoltaic module generates current, since the second switch module is in the closed state, the photovoltaic module can supply power to the electronic components and charge the energy storage module at the same time; the energy storage module and the photovoltaic module can also jointly supply power to the electronic components.

[0060] When the power supply interface is connected to an external power supply and the photovoltaic module does not generate current, the second switch module is in the open state, and the first switch module and the third switch module are in the closed state. At this time, the external power supply can supply power to the electronic components through the first switch module and the third switch module path, and charge the energy storage module through the first switch module.

[0061] When the power interface is connected to an external power supply and the photovoltaic module generates current, if the system voltage of the electronic device remains unchanged, it indicates that the photovoltaic module can meet the power demand of the electronic components. At this time, the controller can disconnect the third switch module and the second switch module, and close the first switch module, that is, the external power supply charges the energy storage module, and the photovoltaic module supplies power to the electronic components. If the system voltage of the electronic device drops, it indicates that the photovoltaic module cannot meet the power demand of the electronic components. At this time, the controller can disconnect the third switch module and close the first switch module and the second switch module. At this time, the external power supply charges the energy storage module, and the photovoltaic module and the external power supply jointly supply power to the electronic components, or the photovoltaic module, the external power supply, and the energy storage module jointly supply power to the electronic components.

[0062] In some embodiments, as Figure 5 shown, the photovoltaic module 110 includes a photovoltaic charging module 1101; the electronic device 100 further includes a DC charging module 170; the DC charging module 170 is connected to the power interface 130; wherein,

[0063] the controller is configured to obtain voltage information of the energy storage module when the connection situation indicates that the power interface is connected to an external power supply and the photovoltaic module generates electrical energy;

[0064] the controller is configured to determine first output voltage information of the photovoltaic charging module and second output voltage information of the DC charging module based on the voltage information of the energy storage module; the first output voltage information and the second output voltage information are greater than the voltage information of the energy storage module;

[0065] the photovoltaic charging module is configured to supply power to the electronic components based on the first output voltage information and / or charge the energy storage module based on the first output voltage information;

[0066] the DC charging module is configured to supply power to the electronic components based on the second output voltage information and / or charge the energy storage module based on the second output voltage information.

[0067] In the embodiments of the present application, when the connection situation indicates that the power interface is connected to an external power supply and the photovoltaic module generates electrical energy, the controller can obtain the voltage information of the energy storage module through the Inter-Integrated Circuit (I2C) protocol.

[0068] It can be understood that in order for the photovoltaic module and the external power supply to supply power to the electronic components and charge the energy storage module, the output voltages of the photovoltaic module and the external power supply need to be less than the voltage of the energy storage module. Therefore, by setting the charging voltage for the photovoltaic charging module in the photovoltaic module and the charging voltage for the DC charging module through the controller, it is possible to achieve the photovoltaic module and the external power supply supplying power to the electronic components and charging the energy storage module.

[0069] In some embodiments, the above-mentioned photovoltaic charging module may be a Maximum Power Point Tracking Charger (MPPT Charger), and the DC charging module may be a Narrow Voltage Direct Current Charger (NVDC Charger).

[0070] In some embodiments, as Figure 6 shown, the photovoltaic module includes a photovoltaic charging module 1101 and a photovoltaic unit 1102; the photovoltaic charging module 1101 includes a photovoltaic charging management module 11011; the controller is configured to:

[0071] Obtain the current information and voltage information of the photovoltaic unit;

[0072] Based on the current information and voltage information of the photovoltaic unit, determine the maximum input power of the photovoltaic unit;

[0073] Based on the maximum input power of the photovoltaic unit, determine the power supply strategy of the photovoltaic charging management module.

[0074] In the embodiments of the present application, the photovoltaic unit may be a solar panel for converting solar energy into electrical energy. The acquisition unit in the electronic device can acquire multiple current information and multiple current information of the photovoltaic unit within a predetermined time period, and send the multiple current information and multiple voltage information acquired in real time to the controller.

[0075] In the embodiments of the present application, after the controller obtains multiple current information and multiple current information of the photovoltaic unit within a predetermined time period, it can determine the characteristic curve of the photovoltaic unit under this predetermined time period based on the multiple current information and multiple current information, and determine the maximum input power of the photovoltaic unit based on this characteristic curve.

[0076] In some embodiments, it is possible to first determine the current / voltage response curve of the photovoltaic unit under this predetermined time period based on multiple current information and multiple current information, and then determine the characteristic curve based on the current / voltage response curve.

[0077] Exemplarily, as Figure 7As shown, curve 701 is the current / voltage response curve of a photovoltaic unit during a certain period. Based on curve 701, characteristic curve 702 can be obtained, and based on characteristic curve 702, the maximum input power 703 of the photovoltaic unit during this period can be obtained. As Figure 8 As shown, curve 801 is the characteristic curve of the battery in the photovoltaic unit at 25°C and with a light intensity of 1000 W / m2; curve 802 is the characteristic curve of the battery in the photovoltaic unit at 25°C and with a light intensity of 800 W / m2; curve 803 is the characteristic curve of the battery in the photovoltaic unit at 25°C and with a light intensity of 600 W / m2.

[0078] In the embodiments of the present application, the controller can obtain the current and voltage generated by the photovoltaic unit converting solar energy in real time, then determine the maximum input power of the photovoltaic unit based on the current and voltage currently generated by the photovoltaic unit, and finally adjust the power supply strategy of the photovoltaic charging management module in real time based on the maximum input power of the photovoltaic unit. In this way, the power supply strategy of the photovoltaic charging management module can be matched with the maximum input power of the photovoltaic unit, thereby improving the utilization rate of solar energy.

[0079] In some embodiments, the above-mentioned controller can be an independent controller. For example, the controller can be an EC, a CPU, and an AI chip (Artificial Intelligence Chip). In other embodiments, the controller can also include multiple control sub-modules, and each control sub-module communicates with each other to complete the control function of the entire controller. Exemplarily, the control sub-modules in the controller can be an EC, a CPU, etc.

[0080] In some embodiments, the above-mentioned controller is further configured to: determine a target power range from a plurality of predetermined power ranges based on the maximum input power of the photovoltaic unit; determine the output current range corresponding to the target power range as the power supply strategy of the photovoltaic charging management module.

[0081] In the embodiments of the present application, the power range into which the maximum input power falls among the multiple power ranges can be determined as the target power range.

[0082] In the embodiments of the present application, different power ranges have corresponding relationships with different output current ranges, and the controller can determine the output current range corresponding to the target power range based on the target power range and the multiple corresponding relationships.

[0083] In the embodiments of the present application, the power supply strategy of the photovoltaic charging management module can refer to that the photovoltaic charging management module supplies power to the electronic components and / or energy storage module using the current within the output current range.

[0084] In some embodiments, as Figure 9As shown, the electronic device further includes a plurality of fourth switch modules 901 and a fifth switch module 902; the controller 190 is respectively connected to the photovoltaic charging management module 1101 through the fourth switch modules 901 whose quantity corresponds to the quantity of the plurality of power ranges; the photovoltaic charging module further includes a fifth switch module 902; the photovoltaic charging management module 1101 is connected to the electronic component 120 through the fifth switch module 902; wherein,

[0085] The controller is configured to close the fourth switch module corresponding to the target power range.

[0086] The photovoltaic charging management module is configured to turn on the fifth switch module based on the high-level signal generated by the closing of the fourth switch module, so that the current value passing through the fifth switch module is within the output current range.

[0087] As Figure 9 shown, when the photovoltaic unit 1102 converts solar energy into electrical energy, the acquisition unit 180 can acquire the current and voltage of the photovoltaic unit 1102 and send the current and voltage of the photovoltaic unit 1102 to the controller 190. After the controller 190 determines the maximum input power of the photovoltaic unit 1102 based on the current and voltage of the photovoltaic unit 1102, it can determine the target power range in which the maximum input power falls. Then the controller 190 closes the fourth switch module 901 corresponding to the target power range, and the controller 190 can transmit a high-level signal to the photovoltaic charging management module 1101 through the closed fourth switch module 901. The photovoltaic charging management module 1101 can turn on the fifth switch module 902 based on the high-level signal, so that the current value passing through the fifth switch module 902 is within the output current range.

[0088] In the embodiment of the present application, after determining the target power range, the controller can transmit a level signal for closing the fourth switch module to the fourth switch module corresponding to the target power range, so as to realize closing the fourth switch module corresponding to the target power range. Exemplarily, the plurality of fourth switch modules can be triodes, and the controller can transmit a level signal to the base of the triode, so as to realize closing the fourth switch module.

[0089] In the embodiment of the present application, when the fifth switch module is a triode, the controller can control the current flowing into the base of the fifth switch module, so that the current value passing through the fifth switch module is within the output current range.

[0090] In some embodiments, the controller is further configured to send indication information carrying an output current range to the photovoltaic charging management module; the photovoltaic charging management module is configured to determine voltage information corresponding to the output current range based on the indication information; and based on the voltage information corresponding to the output current range, turn on the fifth switch module, so that the current value passing through the fifth switch module 902 is within the output current range.

[0091] In some embodiments, the electronic device further includes a power limit module; the controller is configured to determine a power limit range of the electronic component based on a target power range of the photovoltaic unit; the controller is configured to send the power limit range of the electronic component to the power limit module; the power limit module is configured to limit the load power of the electronic component based on the power limit range. Exemplarily, the power limit module may be a Basic Input / Output System (BIOS).

[0092] In an embodiment of the present application, after determining the target power range based on the maximum input power, the controller may determine the power limit range of the electronic component based on the target power range of the photovoltaic unit. Among them, the corresponding relationship between different power ranges and different power limit ranges is stored in the controller, and the power limit range of the electronic component is determined through the corresponding relationship between different power ranges and different power limit ranges.

[0093] Exemplarily, when the electronic component is a CPU and the target power range is above 9.62W, the power limit range of the CPU may be PL1 of PL (Power Limit) 1 / PL2 / PL4; when the target power range is 7.62W to 9.62W, the power limit range of the CPU may be PL2; when the target power range is below 7.62W, the power limit range of the CPU may be PL3.

[0094] In an embodiment of the present application, when determining the power supply strategy of the photovoltaic charging management module, the controller can determine the power limit range corresponding to the target power range of the electronic component, and then the power limit module limits the load power of the electronic component based on the power limit range. In this way, the load power of the electronic component can be made to conform to the power supply strategy of the photovoltaic module, so that the electronic device can operate normally, and the electric energy converted from solar energy can be fully utilized, reducing unnecessary losses and lowering the energy cost.

[0095] In some embodiments, an embodiment of the present application provides a control method, which is applied to the above-mentioned controller; the control method can be implemented through step S101 to step S103:

[0096] Step S101, obtain the current information and voltage information of the photovoltaic unit;

[0097] Step S102, determine the maximum input power of the photovoltaic unit based on the current information and voltage information of the photovoltaic unit;

[0098] Step S103, determine the power supply strategy of the photovoltaic charging management module based on the maximum input power of the photovoltaic unit.

[0099] In some embodiments, the above step S103 can be implemented through step S1031 and step S1032:

[0100] Step S1031, determine the target power range among a plurality of predetermined power ranges based on the maximum input power of the photovoltaic unit.

[0101] Step S1032, determine the output current range corresponding to the target power range as the power supply strategy of the photovoltaic charging management module.

[0102] In some embodiments, the above control method can also be implemented through steps S201 to S202:

[0103] Step S201, determine the power limit range of the electronic component based on the target power range of the photovoltaic unit.

[0104] Step S202, send the power limit range of the electronic component to the power limit module; wherein, the power limit module is used to limit the load power of the electronic component based on the power limit range.

[0105] In some embodiments, the present application provides a strategy setting method for a solar charger. The strategy setting method includes the following steps:

[0106] Step S301, the EC determines the characteristic curve of the solar panel according to the measured data of the solar panel.

[0107] Here, the measured data of the solar panel can be the voltage and current of the solar panel.

[0108] Step S302, the EC determines the maximum input power of the solar panel based on the characteristic curve.

[0109] Step S303, the EC determines the target range among three preset ranges based on the maximum input power of the solar panel.

[0110] Among them, the three preset ranges can include 7w to 9w, 9w to 13w, and above 13w. Each range corresponds to the current setting of the solar charger.

[0111] Step S304: Based on the target range, the EC turns on the target switch corresponding to the target range among multiple switches, or the EC sends indication information corresponding to the target range to the management module of the solar charger based on the communication protocol.

[0112] Step S305: The EC sends the power limit gear corresponding to the target range to the basic input / output system.

[0113] Step S306: The management module of the solar charger obtains the high-level signal corresponding to the target switch, determines the corresponding voltage information based on the high-level signal corresponding to the target switch, or the management module of the solar charger determines the corresponding voltage information in response to the indication information.

[0114] Step S307: The management module of the solar charger turns on the switch module based on the voltage information, so that the solar charger provides a current corresponding to the target range to the electronic device.

[0115] Step S308: The basic input / output system limits the load power of the electronic device based on the power limit gear.

[0116] In some embodiments, as Figure 10 shown, the electronic device includes a first interface 1002 (corresponding to the power interface in the above embodiments), a narrow-voltage DC charger 1003 (corresponding to the DC charging module in the above embodiments), a first switch S1 (corresponding to the first switch module in the above embodiments), a second switch S2 (corresponding to the third switch module in the above embodiments), a third switch S3 (corresponding to the second switch module in the above embodiments), a battery 1004 (corresponding to the energy storage module in the above embodiments), a system 1005 (corresponding to the electronic components in the above embodiments), a solar charger 1006 (corresponding to the photovoltaic charging module in the above embodiments), a second interface 1007, and a solar panel 1008 (corresponding to the photovoltaic unit in the above embodiments). The power adapter 1001 is connected to the narrow-voltage DC charger 1003 through the first interface 1002; the narrow-voltage DC charger 1003 is connected to the battery 1005 through the first switch S1, and the narrow-voltage DC charger 1003 is connected to the system 1005 through the second switch S2; the battery 1005 is connected to the system 1005 through the third switch S3; the solar panel 1008 is connected to the solar charger 1006 through the second interface 1007, and the solar charger 1006 is connected to the battery 1004 through the third switch S3; the solar charger 1006 is connected to the system 1005;

[0117] Among them, the first interface 1002 can be a Type-C interface for connecting to the power adapter 1001; the second interface 1007 can be a motherboard connector (MB Conn).

[0118] In the embodiments of the present application, the PD module (Power Delivery) in the electronic device identifies whether a power adapter is connected. When no power adapter is connected, the EC controls S3 to disconnect, and the device is in the DC only mode. S1 and S2 are turned on, and the battery powers the system. Here, the PD module is a chip on the electronic device responsible for the PD protocol, and this chip uses the PD protocol to communicate with the Type-C adapter to determine the adapter type and its presence.

[0119] When the solar panel obtains solar energy, S1 and S2 disconnect, and S3 turns on. The solar energy is used to power the system and charge the battery through the solar charger. When the solar power is greater than the system demand, the excess power is used for battery charging. When the solar power is less than the system demand, the insufficient power is dynamically compensated by the battery discharging to the system.

[0120] It can be understood that the EC directly obtains the battery voltage of the battery through the Inter-Integrated Circuit (I2C) protocol.

[0121] Then the EC actively sets an output voltage for the solar charger according to the battery voltage, which also corresponds to the system voltage. Here, the output voltage is greater than the battery voltage. Since there is a linear relationship between the battery voltage and the system voltage, the output voltage set based on the battery voltage corresponds to the system voltage.

[0122] When the system demand power increases, it will pull down the system voltage, and the solar charger will maintain the system voltage constant by outputting current. If the solar power is greater than the system demand, the system voltage will not change. Because the output voltage is greater than the battery voltage, the solar charger will also charge the battery.

[0123] If the system demand is greater than the output power of the solar energy, the current output by the solar charger cannot maintain the system voltage, resulting in a decrease in the system voltage. In the case where the system voltage continues to drop (i.e., the output power of the solar energy is less than the system demand power), the solar charger reduces its own output voltage until the output voltage is equal to the battery voltage. At this time, the solar charger completely powers the system. If the system continues to increase the power demand, it will cause the system voltage to continue to drop, so that the system voltage is lower than the battery voltage, and the battery will discharge to the system.

[0124] In the embodiments of the present application, when the power adapter is connected, S3 disconnects, and the device is in the AC mode. S1 and S2 turn on, and the power adapter powers the system and charges the battery.

[0125] In an embodiment of the present application, when the solar panel obtains solar energy, S2 is disconnected, S3 is turned on, and S1 is turned on. At this time, solar energy preferentially powers the system, and the power adapter charges the battery.

[0126] It can be understood that when the electronic device is connected to the power adapter and the solar panel obtains solar energy, the EC sets the output voltages of the narrow-voltage DC charger and the solar charger based on the battery voltage. The voltage set by the narrow-voltage DC charger is greater than the battery voltage for charging the battery. Since there is an uncontrollable risk in charging the battery in parallel, when the EC determines that the electronic device is connected to the power adapter and the solar panel obtains solar energy, S3 is disconnected to prohibit the solar charger from charging the battery, thus enabling the power adapter to charge the battery.

[0127] In an embodiment of the present application, when the solar panel obtains solar energy, S3 is turned on, and the power adapter compensates for the insufficient power of the system.

[0128] It can be understood that when the output power of the solar charger is greater than the system power, the power adapter charges the battery and the solar energy powers the system. When the system power is greater than the solar power, it will cause the system voltage to be lower than the battery voltage. At this time, the charging path from the power adapter to the battery will be shunted by the lower system voltage, so that a part of the charging power compensates for the system, and the remaining part is used for battery charging, thus enabling the power adapter and the solar charger to jointly provide power for the system.

[0129] When the total power of the power adapter and the solar charger still cannot meet the system requirements, the battery will discharge to complete the compensated power supply for the system. This is because when the system voltage is lower than the battery voltage, the solar charger will supply all the power to the system, and the charging power of the power adapter will be affected by the lower system voltage and a part of the charging power will be shunted to the system. If the system demand power further increases, it will cause the system voltage to drop too much until the charging power provided by the power adapter completely compensates for the system demand. The battery will no longer charge and will be affected by the lower system voltage and discharge to the system. Thus, the battery, the solar charger, and the power adapter jointly supply power to the system.
