DETAILED DESCRIPTION

[0029] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. Throughout the accompanying drawings, the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. Furthermore, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary and are intended only to explain the embodiments of the present application and are not to be construed as limiting the present application.

[0030] With the increasing development of renewable energy technology, the application of photovoltaic technology in various fields has become more and more extensive. In the field of solar photovoltaic applications, photovoltaic devices, such as photovoltaic awnings, are widely used because they have the characteristics of blocking sunlight while generating electricity. In related technologies, a photovoltaic device includes a support assembly, a photovoltaic assembly and a socket. The photovoltaic assembly is electrically connected to the socket and is both provided on the support assembly. Generally, the device to be charged needs to be aligned and plugged into the socket before the charging function can be realized, and the operation convenience is poor. In order to solve this problem, an embodiment of the present application provides a photovoltaic device 100 ( Figure 1 As shown), a charging control method for a photovoltaic device ( Figure 3 shown) and storage medium 300 ( Figure 8 shown).

[0031] See also Figure 1 and Figure 2 The photovoltaic device 100 according to the embodiment of the present application includes a base 10, a support assembly 30, and a wireless charging assembly 70. The support assembly 30 is connected to the base 10; the photovoltaic assembly 50 is mounted on the support assembly 30; and the wireless charging assembly 70 is electrically connected to the photovoltaic assembly 50 and includes at least two transmitting coils 71 arranged in an array within the base 10 and configured to charge a device to be charged on the base 10. It should be noted that in some embodiments, the device to be charged includes, but is not limited to, electric vehicles, drones, and power tools.

[0032] It is understandable that the photovoltaic device 100 includes, but is not limited to, photovoltaic houses, photovoltaic awnings, photovoltaic carports, ground power stations, and water surface photovoltaics. In the embodiment of the present application, the photovoltaic device 100 includes a photovoltaic awning as an example for explanation. Among them, the photovoltaic awning is a photovoltaic product that can use solar energy to generate electricity while providing shade, heat insulation, and rain protection. The photovoltaic awning can be used in areas such as the periphery of outdoor public and large commercial facilities or the courtyard of a private residence. For example, the photovoltaic awning can be set on the roof to be used as a sunshade facility; or, the photovoltaic awning can be set in the courtyard to be used as a sunshade.

[0033] The base 10 is a structure within the photovoltaic device 100 that supports the support assembly 30 and other devices. Serving as the foundation for the photovoltaic device 100, the base 10 provides greater stability for the support assembly 30 and the photovoltaic modules 50 mounted thereon. The base 10 can be made of materials such as metal or high-strength plastic. The base 10 is connected to a surface to be secured and provides a user with a place to stand or a place for a device to be charged to rest. The surface to be secured includes, but is not limited to, the ground.

[0034] The support assembly 30 is a structure in the photovoltaic device 100 that can at least provide installation and support for the photovoltaic assembly 50. The support assembly 30 can be made of metal and / or non-metallic materials, and metal materials include but are not limited to aluminum, iron, steel or aluminum alloys, and non-metallic materials include but are not limited to plastics. Exemplarily, the support assembly 30 can be made of metal materials, for example, the support assembly 30 can be made of aluminum alloy, which can improve the structural strength of the support assembly 30, enhance the ability of the photovoltaic device 100 to withstand the external environment (such as wind, rain, snow, etc.), and ensure the stability and reliability of the operation of the photovoltaic device 100. It should be noted that, in some embodiments, the overall shape of the support assembly 30 can include but is not limited to square, cylindrical and diamond shapes. In this way, the support assembly 30 can adapt to the installation of photovoltaic assemblies 50 of different sizes and shapes.

[0035] The photovoltaic assembly 50 is a structure within the photovoltaic device 100 that converts solar energy into electrical energy. The photovoltaic assembly 50 can be mounted on top of the support assembly 30 or at a specific mounting location on the support assembly 30. In certain embodiments of the present application, the photovoltaic assembly 50 includes a photovoltaic panel, which is used to convert solar energy into electrical energy. The photovoltaic panel can be a different type of solar energy conversion device, such as monocrystalline silicon, polycrystalline silicon, or thin-film solar cells. Users can select photovoltaic panels of varying efficiencies and sizes based on their needs and the frame structure.

[0036] In some embodiments, the photovoltaic assembly 50 can be mounted on the support assembly 30 using a detachable connection method, which facilitates the removal of the photovoltaic assembly 50 from the support assembly 30 when maintenance or replacement is required. Examples of detachable connection methods include, but are not limited to, bolt connections and snap connections. In other embodiments, the photovoltaic assembly 50 can be mounted on the support assembly 30 using a non-detachable connection method. This can enhance the bonding strength between the photovoltaic assembly 50 and the support assembly 30, improve the ability of the photovoltaic device 100 to withstand external environmental factors, and ensure the stability and reliability of the operation of the photovoltaic device 100. Examples of non-detachable connection methods include, but are not limited to, bonding or welding.

[0037] In certain embodiments of the present application, the support assembly 30 includes a plurality of frames 31 and a plurality of columns 33. The plurality of frames 31 are used together to mount the photovoltaic assembly 50. The upper end of each column 33 is used to connect two adjacent frames 31, and the lower end is used to connect to the base 10. The columns 33 can be combined with the base 10 by bolting, welding, plugging or snapping. In one example, the column 33 has a fixed length. In another example, the column 33 is a retractable structure. For example, the column 33 may include at least two sub-columns, and the at least two sub-columns are retractably connected together, so that the user can adjust the distance between the frame 31 assembly and the base 10 according to specific usage requirements.

[0038] In one embodiment, the lengths of the plurality of columns 33 are the same. Thus, when the gravity and / or external load of the photovoltaic assembly 50 acts on the columns 33, the plurality of columns 33 can more evenly transmit and disperse the pressure, achieving uniform distribution of pressure, thereby improving the structural stability of the frame structure. In another embodiment, the lengths of at least some of the plurality of columns 33 are different. Thus, columns 33 of appropriate lengths can be selected according to the actual use environment of the photovoltaic device 100, thereby improving the applicability of the photovoltaic device 100. For example, when the cross-sectional shape of the installation space (for installing the photovoltaic assembly 50) formed by the plurality of frames 31 is rectangular, the lengths of the two columns 33 connected to the frames 31 forming the short sides of the installation space are different, and the lengths of the two columns 33 connected to the frames 31 forming the long sides of the installation space are the same. In this way, when the photovoltaic assembly 50 is installed in the installation space, the photovoltaic assembly 50 is tilted relative to the horizontal plane (the plane perpendicular to the direction of gravity).

[0039] In certain embodiments of the present application, the photovoltaic device 100 further includes an energy storage unit 80 , which is electrically connected to both the photovoltaic component 50 and the wireless charging component 70 and is disposed within the base 10 .

[0040] Specifically, in certain embodiments, the energy storage unit 80 can store the electrical energy generated by the photovoltaic assembly 50 and can power loads such as the wireless charging assembly 70, household appliances, and portable devices. The energy storage unit 80 is disposed within the base 10, which can improve the integration of the photovoltaic device 100. There is no need to separately install the energy storage unit 80 outside the photovoltaic device 100, reducing external components. This, on the one hand, makes the overall structure of the photovoltaic device 100 more compact; on the other hand, it can prevent the external wiring from being too complicated and reduce visual defects. Furthermore, the energy storage unit 80 is disposed within the base 10, so that the base 10 can provide protection for the energy storage unit 80, reduce the possibility of damage to the energy storage unit 80 caused by external environmental factors, and extend the service life of the energy storage unit 80.

[0041] More specifically, the energy storage unit 80 and the photovoltaic assembly 50 can be electrically connected directly via a cable (e.g., a copper wire, aluminum wire, or other conductive material), or can be electrically connected via an intermediate device such as a junction box or a busbar. It should be noted that in some embodiments, the energy storage unit 80 can be a lithium-ion battery, a lead-acid battery, or another type of rechargeable battery.

[0042] In some embodiments, the energy storage unit 80 includes at least two, and the at least two energy storage units 80 are electrically connected to the at least two transmitting coils 71 in a one-to-one correspondence. This improves the reliability of the photovoltaic device 100 in charging the device to be charged. That is, damage to one energy storage unit 80 will not affect the normal operation of the remaining energy storage units 80, ensuring that the photovoltaic device 100 can charge the device to be charged. Furthermore, each energy storage unit 80 only provides power to one transmitting coil 71, thereby reducing the heat generated by the energy storage unit 80 and reducing the possibility of overheating and damage to the energy storage unit 80.

[0043] In other embodiments, one energy storage unit 80 is provided, and one energy storage unit 80 is electrically connected to at least two transmitting coils 71. This reduces the number of energy storage units 80, thereby reducing the hardware requirements of the photovoltaic device 100 and facilitating miniaturization of the photovoltaic device 100. The present embodiment is described using one energy storage unit 80 as an example.

[0044] Wireless charging assembly 70 is a structure within photovoltaic device 100 used to charge the device to be charged. Wireless charging assembly 70 includes, but is not limited to, magnetic resonance wireless charging assembly, electromagnetic induction wireless charging assembly, radio frequency wireless charging assembly, laser wireless charging assembly, ultrasonic wireless charging assembly, capacitive coupling wireless charging assembly, and microwave wireless charging assembly. In the present embodiment, the wireless charging assembly 70 is described as including a magnetic resonance wireless charging assembly.

[0045] Specifically, in certain embodiments, when a device to be charged is parked on the base 10, the energy storage unit 80 can provide electrical energy to the transmitting coil 71 corresponding to the device to be charged, so that the transmitting coil 71 generates a magnetic field. The magnetic field can excite the receiving coil in the device to be charged through resonant coupling, and the receiving coil can convert the magnetic energy into electrical energy, thereby achieving wireless charging. Moreover, in the present application, the transmitting coil 71 includes at least two, and at least two transmitting coils 71 are arranged in an array within the base 10. As a result, the photovoltaic device 100 in the present application can realize simultaneous power supply to multiple devices, that is, the photovoltaic device 100 in the present application can charge multiple devices to be charged at the same time.

[0046] In the photovoltaic device 100 of the embodiment of the present application, the wireless charging component 70 is electrically connected to the photovoltaic component 50 and includes at least two transmitting coils 71. The at least two transmitting coils 71 are arranged in an array in the base 10 and are configured to charge the device to be charged on the base 10. That is, when the device to be charged is docked on the base 10, the transmitting coil 71 of the wireless charging component 70 can automatically charge it, realizing charging at the same time as docking. Therefore, compared with the related art in which the charging function is realized after the device to be charged is plugged into the socket, the charging operation is simpler, which is conducive to improving the user experience.

[0047] The photovoltaic device 100 will be further described below with reference to the accompanying drawings.

[0048] See also Figure 1 and Figure 2 In some embodiments, the base 10 is provided with a receiving space 11 and a partition 13 arranged in the receiving space 11. The partition 13 is used to separate the receiving space 11 into at least two subspaces 111. The at least two subspaces 111 correspond one-to-one to at least two transmitting coils 71.

[0049] Specifically, in certain embodiments, the base 10 includes a bottom plate 15, a cover plate 17, and a side plate 19 positioned between the bottom plate 15 and the cover plate 17. The bottom plate 15, the side plate 19, and the cover plate 17 are connected to form a receiving space 11. A partition 13 is disposed between the bottom plate 15 and the cover plate 17 and can be connected to the side plate 19. Thus, the partition 13 can divide the receiving space 11 into at least two independent subspaces 111. There can be one or more partitions 13. If there are multiple partitions 13, the multiple partitions 13 can be arranged crosswise within the receiving space 11. When a device to be charged is parked on the cover plate 17 and corresponds to a subspace 111, the transmitting coil 71 in the subspace 111 can charge the device to be charged.

[0050] More specifically, in some embodiments, the number of subspaces 111 is the same as the number of transmitting coils 71. In this case, each subspace 111 is provided with a transmitting coil 71. Alternatively, the number of subspaces 111 is greater than the number of transmitting coils 71. In this case, some of the subspaces 111 are provided with transmitting coils 71, while other subspaces 111 are provided with other devices or are left vacant. For example, another subspace 111 is provided with an energy storage unit 80.

[0051] It is understandable that when at least two transmitting coils 71 are operating simultaneously, the magnetic fields generated by adjacent transmitting coils 71 may overlap, resulting in reduced energy transmission efficiency or eddy current loss, affecting charging efficiency. In addition, if the operating frequencies of the transmitting coils 71 are the same, resonance or signal crosstalk may occur during the charging process, affecting charging stability.

[0052] In certain embodiments of the present application, the partition 13 is made of a magnetic shielding material. This prevents the magnetic fields generated by two adjacent transmitting coils 71 from overlapping, thereby ensuring energy transmission efficiency, reducing eddy current losses, and improving the charging efficiency of the wireless charging assembly 70 for the device being charged. Furthermore, it prevents resonance or signal crosstalk when at least two transmitting coils 71 operate simultaneously, thereby improving the stability and reliability of the wireless charging assembly 70 in charging the device being charged. It should be noted that in certain embodiments, magnetic shielding materials include, but are not limited to, ferrite, nanocrystalline alloys, permalloy, pure iron, and silicon steel sheets.

[0053] See also Figure 1 and Figure 3 , an embodiment of the present application provides a charging control method for a photovoltaic device, the charging control method comprising:

[0054] 01: When there is a device to be charged on the base 10, obtain device information of the device to be charged, the device information including the device type; and

[0055] 03: Adjust the output power of the corresponding transmitting coil 71 according to the device information.

[0056] Please combine Figure 1 The above-mentioned photovoltaic device charging control method can be applied to the photovoltaic device 100. The photovoltaic device 100 of the embodiment of the present application includes a base 10 and a wireless charging component 70. The wireless charging component 70 includes at least two transmitting coils 71. The at least two transmitting coils 71 are arranged in an array within the base 10 and are configured to charge the device to be charged on the base 10. It should be noted that the photovoltaic device 100 of this embodiment is exactly the same as the photovoltaic device 100 in the above-mentioned embodiment, and a repeated description will not be given here.

[0057] Furthermore, in some embodiments, the photovoltaic device 100 also includes a control component 90, which is capable of executing the charging control methods in 01 and 03, that is, the control component 90 is used to obtain device information of the device to be charged when there is a device to be charged on the base 10, the device information including the device type; and adjust the output power of the corresponding transmitting coil 71 according to the device information.

[0058] The control component 90 is a component that is at least used to analyze and process data and can issue instructions to the actuator or control the actuator. It should be noted that in some embodiments, the control component 90 can be a central processing unit (CPU); it can also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), off-the-shelf programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0059] Specifically, in some embodiments, when there is a device to be charged on the base 10, the control component 90 can obtain device information of the device to be charged, the device information including the device type (such as electric vehicle, electric vehicle model, drone, drone model, etc.), and adjust the output power of the corresponding transmitting coil 71 according to the device information, so that the wireless charging component 70 can adaptively charge different devices to be charged.

[0060] More specifically, in certain embodiments, when the control component 90 obtains device information of the device to be charged, the control component 90 can determine a reference power corresponding to the device information based on a preset power model, and adjust the output power of the corresponding transmitting coil 71 based on the reference power. The preset power model can be a known model, which can be a model obtained before the control component 90 leaves the factory, a model manually input after the control component 90 leaves the factory, or a model obtained by the control component 90 processing historical data after the control component 90 leaves the factory.

[0061] In some embodiments, the photovoltaic device 100 further includes a detection component, which is electrically connected to the control component 90 and is configured to detect whether there is a device to be charged on the base 10 .

[0062] Specifically, when a device to be charged is present on the base 10, the detection component can output a detection signal, and the control component 90 can determine whether a device to be charged is present on the base 10 based on the detection signal output by the detection component. It should be noted that in some embodiments, the detection component includes but is not limited to a pressure sensor, a coil impedance detection sensor, and a capacitive proximity sensor.

[0063] In the charging control method for a photovoltaic device according to an embodiment of the present application, a wireless charging assembly 70 is electrically connected to the photovoltaic assembly 50 and includes at least two transmitting coils 71. The at least two transmitting coils 71 are arranged in an array in the base 10 and are configured to charge the device to be charged on the base 10. That is, when the device to be charged is docked on the base 10, the transmitting coil 71 of the wireless charging assembly 70 can automatically charge it, realizing instant charging. Therefore, compared with the related art in which the charging function is realized after the device to be charged is plugged into the socket, the charging operation is simpler, which is conducive to improving the user experience.

[0064] In addition, when there is a device to be charged on the base 10, device information of the device to be charged is obtained, and the device information includes the device type; and the output power of the corresponding transmitting coil 71 is adjusted according to the device information. On the one hand, this can improve the applicability of the wireless charging component 70, so that the wireless charging component 70 can charge different types of devices to be charged; on the other hand, it can improve the stability and reliability of the wireless charging component 70 in charging the device to be charged, and prevent safety problems caused by mismatch between the output power and the device to be charged.

[0065] In addition, the wireless charging component 70 includes at least two transmitting coils 71, and at least two transmitting coils 71 are arranged in an array in the base 10. Therefore, the photovoltaic device 100 in the present application can realize simultaneous power supply for multiple devices, that is, the photovoltaic device 100 in the present application can charge multiple devices to be charged at the same time.

[0066] See also Figure 1 and Figure 4 In some embodiments, the charging control method further includes:

[0067] 05: Obtain the output power of at least two transmitting coils 71; and

[0068] 06: Based on the similarity of the output powers of two adjacent transmitting coils 71 , the two adjacent transmitting coils 71 are controlled to be charged in a time-sharing manner or simultaneously.

[0069] Please combine Figure 1 The control component 90 is further configured to execute the charging control methods in 05 and 06, that is, the control component 90 is configured to obtain the output power of at least two transmitting coils 71; and control the two adjacent transmitting coils 71 to be charged in a time-sharing manner or simultaneously according to the similarity of the output power of the two adjacent transmitting coils 71.

[0070] Specifically, in some embodiments, when there are at least two devices to be charged on the base 10, the control component 90 can obtain the output power of at least two transmitting coils 71 corresponding to the at least two devices to be charged, and control the two adjacent transmitting coils 71 to charge in a time-sharing manner (charging the corresponding devices to be charged in time periods) or charge simultaneously (charging the corresponding devices to be charged synchronously) based on the similarity of the output power of the two adjacent transmitting coils 71.

[0071] Furthermore, please combine Figure 5 In some embodiments, 06: controlling the time-sharing charging or simultaneous charging of the two adjacent transmitting coils 71 based on the similarity of the output powers of the two adjacent transmitting coils 71 includes:

[0072] 061: When the similarity of the output powers of two adjacent transmitting coils 71 is greater than a preset similarity threshold, the two adjacent transmitting coils 71 are controlled to be charged in a time-sharing manner;

[0073] 063: When the similarity of the output powers of two adjacent transmitting coils 71 is less than a preset similarity threshold, the two adjacent transmitting coils 71 are controlled to be charged simultaneously.

[0074] Please combine Figure 1 The control component 90 is further configured to execute the charging control methods in 061 and 063, that is, the control component 90 is configured to control the two adjacent transmitting coils 71 to be charged in a time-sharing manner when the similarity of the output powers of the two adjacent transmitting coils 71 is greater than a preset similarity threshold; and to control the two adjacent transmitting coils 71 to be charged simultaneously when the similarity of the output powers of the two adjacent transmitting coils 71 is less than the preset similarity threshold.

[0075] It should be noted that when the output power of two adjacent transmitting coils 71 is the same, the magnetic fields of the two adjacent transmitting coils 71 will be coupled. Compared with the case where the output power of the two adjacent transmitting coils 71 is different, the magnetic field coupling energy of the two adjacent transmitting coils 71 is higher, resulting in more serious electromagnetic interference, which will affect the charging efficiency and charging stability.

[0076] In certain embodiments of the present application, when the similarity of the output power of two adjacent transmitting coils 71 is greater than a preset similarity threshold, the two adjacent transmitting coils 71 are controlled to charge in a time-sharing manner. That is, when the output power of the two adjacent transmitting coils 71 is approximately the same, there may be significant electromagnetic interference between the two adjacent transmitting coils 71. In this case, the control component 90 can control the two adjacent transmitting coils 71 to charge the corresponding devices to be charged in time-sharing manner, thereby preventing magnetic field coupling between the two adjacent transmitting coils 71, thereby reducing electromagnetic interference and improving charging efficiency and charging stability. When the similarity of the output power of the two adjacent transmitting coils 71 is less than a preset similarity threshold, that is, when the output power of the two adjacent transmitting coils 71 is significantly different, the electromagnetic interference between the two adjacent transmitting coils 71 is relatively weak. In this case, the control component 90 can control the two adjacent transmitting coils 71 to charge the corresponding devices to be charged synchronously.

[0077] It is understandable that the preset similarity threshold can be a known value, which can be a value obtained before the control component 90 leaves the factory, a value manually input after the control component 90 leaves the factory, or a value obtained by the control component 90 processing historical data after the control component 90 leaves the factory.

[0078] For further information, see Figure 1 and Figure 6 In some embodiments, 061: when the similarity of the output powers of two adjacent transmitting coils 71 is greater than a preset similarity threshold, controlling the two adjacent transmitting coils 71 to charge in a time-sharing manner includes:

[0079] 0611: When the similarity of the output powers of two adjacent transmitting coils 71 is greater than a preset similarity threshold, obtaining the priorities of the devices to be charged corresponding to the at least two transmitting coils 71; and

[0080] 0613: Control the time-sharing charging of two adjacent transmitting coils 71 according to the priority.

[0081] Please combine Figure 1 The control component 90 is further configured to execute the charging control methods in 0611 and 0613, namely, the control component 90 is configured to obtain the priorities of the devices to be charged corresponding to the at least two transmitting coils 71 when the similarity of the output powers of the two adjacent transmitting coils 71 is greater than a preset similarity threshold; and 0613: control the time-sharing charging of the two adjacent transmitting coils 71 according to the priority levels.

[0082] Specifically, in certain embodiments, when the similarity between the output powers of two adjacent transmitting coils 71 exceeds a preset similarity threshold, that is, when the output powers of the two adjacent transmitting coils 71 are approximately the same, the control component 90 can obtain the priorities of at least two devices to be charged corresponding to the at least two transmitting coils 71 and control the time-sharing charging of the two adjacent transmitting coils 71 based on the priorities. This ensures that devices to be charged with higher priorities receive power first, thereby improving the user experience.

[0083] More specifically, in certain embodiments, when the priorities of the at least two devices to be charged corresponding to the at least two transmitting coils 71 are the same, the control component 90 can control the alternating charging of the two adjacent transmitting coils 71 according to a predetermined duration. For example, when the predetermined duration is 5 minutes and the priorities of the at least two devices to be charged corresponding to the at least two transmitting coils 71 are the same, the control component 90 can control the alternating charging of the two adjacent transmitting coils 71 at intervals of 5 minutes.

[0084] In some embodiments, the priority of the device to be charged is determined based on at least one of the following: the remaining power of the device to be charged; and the device type of the device to be charged.

[0085] Specifically, in certain embodiments, when the priority of a device to be charged is determined based on the remaining power of the device to be charged, a device to be charged with a lower remaining power has a higher priority. For example, a device to be charged with a remaining power of less than 20% has the highest priority, a device to be charged with a remaining power of greater than 20% but less than 50% has a high priority, a device to be charged with a remaining power of greater than 50% but less than 80% has a medium priority, and a device to be charged with a remaining power of greater than 80% has a low priority.

[0086] When the priority of a device to be charged is determined based on its device type, a device to be charged that is a critical device has a higher priority. For example, a device to be charged that is a medical device has a high priority, a device to be charged that is a communication device (such as a mobile phone) has a medium priority, and a device to be charged that is a gaming device (such as an electronic game console) has a low priority.

[0087] When the priority of the device to be charged is determined based on the remaining power of the device to be charged and the device type of the device to be charged, when the device to be charged is a medical device, the priority of the device to be charged is high, regardless of the remaining power; when the device to be charged is a non-medical device (such as communication equipment and gaming equipment, etc.), the priority is determined according to the remaining power.

[0088] See also Figure 1 and Figure 7 In some embodiments, the charging control method further includes:

[0089] 07: Obtain the priorities of the devices to be charged corresponding to at least two transmitting coils 71;

[0090] 08: Obtain the remaining power of the energy storage unit 80; and

[0091] 09: When the remaining power is less than the preset power threshold, the transmitting coil 71 corresponding to the low-priority device to be charged is controlled to stop charging.

[0092] Please combine Figure 1 The control component 90 is further configured to execute the charging control methods in 07, 08, and 09, that is, the control component 90 is configured to obtain the priorities of the devices to be charged corresponding to the at least two transmitting coils 71; obtain the remaining power of the energy storage unit 80; and control the transmitting coil 71 corresponding to the device to be charged with the lower priority to stop charging when the remaining power is less than a preset power threshold.

[0093] Specifically, in some embodiments, when the remaining power is less than a preset power threshold, the control component 90 can control the transmitting coil 71 corresponding to the low-priority device to be charged to stop charging, thereby ensuring that when the power of the energy storage unit 80 is insufficient, the high-priority device to be charged can obtain power supply first, thereby ensuring the normal use of the high-priority device to be charged and improving the user experience.

[0094] See also Figure 1 and Figure 8 The present application also provides a storage medium 300 on which a computer program 310 is stored. When the computer program 310 is executed by one or more processors 330, the charging control method as described in any of the previous embodiments is implemented.

[0095] For example, please combine Figure 3 When the computer program 310 is executed by the processor 330, the following charging control method is implemented:

[0096] 01: When there is a device to be charged on the base 10, obtain device information of the device to be charged, the device information including the device type; and

[0097] 03: Adjust the output power of the corresponding transmitting coil 71 according to the device information.

[0098] For another example, when the computer program 310 is executed by the processor 330 , the charging control methods in 05 , 06 , 061 , 063 , 0611 , 0613 , 07 , 08 , and 09 can also be implemented.

[0099] It should be noted that the charging control method of the photovoltaic device and the explanation of the photovoltaic device 100 in the aforementioned embodiment are also applicable to the storage medium 300 in the embodiment of the present application, and will not be elaborated here.

[0100] In the storage medium 300 in the present application, the wireless charging component 70 is electrically connected to the photovoltaic component 50 and includes at least two transmitting coils 71. The at least two transmitting coils 71 are arranged in an array in the base 10 and are configured to charge the device to be charged on the base 10. That is, when the device to be charged is docked on the base 10, the transmitting coil 71 of the wireless charging component 70 can automatically charge it, realizing instant charging. Therefore, compared with the related art in which the charging function is realized after the device to be charged is plugged into the socket, the charging operation is simpler, which is conducive to improving the user experience.

[0101] In addition, when there is a device to be charged on the base 10, device information of the device to be charged is obtained, and the device information includes the device type; and the output power of the corresponding transmitting coil 71 is adjusted according to the device information. On the one hand, this can improve the applicability of the wireless charging component 70, so that the wireless charging component 70 can charge different types of devices to be charged; on the other hand, it can improve the stability and reliability of the wireless charging component 70 in charging the device to be charged, and prevent safety problems caused by mismatch between the output power and the device to be charged.

[0102] In addition, the wireless charging component 70 includes at least two transmitting coils 71, and at least two transmitting coils 71 are arranged in an array in the base 10. Therefore, the photovoltaic device 100 in the present application can realize simultaneous power supply for multiple devices, that is, the photovoltaic device 100 in the present application can charge multiple devices to be charged at the same time.
