A photovoltaic module 2 is fixed to the first plate 11, and an energy storage module 3 and a charge / discharge control module 4 are housed within the partitioned areas. This integrates the photovoltaic module 2, energy storage module 3, charge / discharge control module 4, and frame assembly 1 into a single unit, resulting in high integration, improved space utilization, and ease of use. It requires no prior installation and can be used plug-and-play, enhancing the user experience. Furthermore, the power supply device 100 features a modular design, facilitating the assembly of multiple power supply devices 100 into a power system 1000.

[0029] In some implementation methods, please refer to Figures 1 to 3 In the embodiment shown, the photovoltaic module 2 includes an encapsulation layer 21 and a solar cell array 22. The encapsulation layer 21 and the solar cell array 22 are stacked sequentially in a first direction. The solar cell array 22 and the encapsulation layer 21 are bonded and fixed by a first adhesive layer 23, and the solar cell array 22 is bonded and fixed to the first plate 11 by a second adhesive layer 24. This not only facilitates processing but also reduces processing costs.

[0030] In this embodiment, the encapsulation layer 21 serves to protect the solar cell array 22. As an example, the encapsulation layer 21 can be photovoltaic glass, or it can be a transparent polymer material such as ethylene-tetrafluoroethylene copolymer or polyvinylidene fluoride, or a laminated composite structure thereof. The first adhesive layer 23 ensures a strong bond between the encapsulation layer 21 and the solar cell array 22. As an example, the first adhesive layer 23 can be, but is not limited to, a POE (Polyolefin Elastomer) film or an EVA (Ethylene-Vinyl Acetate Copolymer) film. The solar cell array 22 can be, but is not limited to, silicon cells, cadmium telluride cells, copper indium gallium selenide cells, perovskite cells, or perovskite / silicon tandem cells. The second adhesive layer 24 ensures a strong bond between the photovoltaic module 2 and the frame module 1. The second adhesive layer 24 can be, but is not limited to, a POE film, an EVA film, polyurethane adhesive, or epoxy resin.

[0031] As an example, the thickness of the encapsulation layer 21 in the first direction can be from 0.03 mm to 3.2 mm. For example, the thickness of the encapsulation layer 21 in the first direction can be, but is not limited to, 0.03 mm, 0.1 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.3 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 3.2 mm, etc.

[0032] In other implementations, please refer to Figure 4 In the embodiment shown, the photovoltaic module 2 includes an encapsulation layer 21, a solar cell array 22, and a backsheet layer 25. The encapsulation layer 21, the solar cell array 22, and the backsheet layer 25 are stacked sequentially in a first direction. The solar cell array 22 and the encapsulation layer 21 are bonded and fixed by a first adhesive layer 23. The solar cell array 22 is bonded and fixed to the backsheet layer 25 by a third adhesive layer 26. The backsheet layer 25 is fixed to the first plate 11 by a fourth adhesive layer 27.

[0033] It is understood that the third adhesive layer 26 can be, but is not limited to, POE film or EVA film, and the material of the fourth adhesive layer 27 can be the same as that of the second adhesive layer 24. The backsheet layer 25 can be, but is not limited to, polyethylene terephthalate or polyvinylidene fluoride, etc., as photovoltaic backsheets. Alternatively, the backsheet layer 25 can also be other polymer materials such as PI (polyimide), and the backsheet layer 25 can also be photovoltaic glass, etc.

[0034] In some implementation methods, please refer to Figures 1 to 4 Multiple partitioned areas include a first partitioned area 14, in which the energy storage component 3 and the charge / discharge control component 4 are housed.

[0035] In this embodiment, the energy storage component 3 and the charge / discharge control component 4 are housed in the same partitioned area, which not only facilitates installation but also facilitates electrical connection between the charge / discharge control component 4 and the energy storage component 3.

[0036] In some implementation methods, please refer to Figures 1 to 4 The remaining partitioned areas are filled with the core layer 15, thereby further increasing the strength and rigidity of the power supply device 100. As an example, the core layer 15 can be... Figures 1 to 4 The honeycomb structure panel shown, or the sandwich layer 15, can also be a corrugated structure panel, an I-beam structure panel, or a combination of the above.

[0037] In one embodiment, the first plate 11, the second plate 12, the partition plate 13, and the sandwich layer 15 can be an integrally formed structure; alternatively, the first plate 11, the second plate 12, the partition plate 13, and the sandwich layer 15 can be connected and fixed by means of bonding or welding. As an example, the materials of the first plate 11, the second plate 12, the partition plate 13, and the sandwich layer 15 can be metal materials such as aluminum or steel; the materials of the first plate 11, the second plate 12, the partition plate 13, and the sandwich layer 15 can also be fiber materials such as glass fiber, carbon fiber, or basalt fiber; and the materials of the first plate 11, the second plate 12, the partition plate 13, and the sandwich layer 15 can also be engineering plastics such as polyvinyl chloride, polyethylene terephthalate, polytetrafluoroethylene, or aramid.

[0038] In some examples, the thickness of the sandwich layer 15 in the first direction is not less than 10 mm, thereby further ensuring the strength and rigidity of the power supply device 100. As an example, the thickness of the sandwich layer 15 in the first direction can be, but is not limited to, 10 mm, 11 mm, 13 mm, or 15 mm, etc.

[0039] As one implementation, the partition plate 13 and the sandwich layer 15 can be integrated into one unit, which can further simplify the structure of the power supply device 100. That is, the partition plate 13 itself is a honeycomb structure plate, a corrugated structure plate, an I-shaped structure plate, a combination of the above-mentioned plate structures, or a combination of the above-mentioned plate structures with other plate structures. Except for the first partition area 14, which is a cavity area, the remaining areas of the partition plate 13 are non-cavity areas with honeycomb or other structures.

[0040] In some implementation methods, please refer to Figure 1 , Figure 2 and Figure 4The thickness of the energy storage component 3 in the first direction is less than the thickness of the sandwich layer 15 in the first direction, and the thickness of the charge and discharge control component 4 in the first direction is less than the thickness of the sandwich layer 15 in the first direction. This not only allows the sandwich layer 15 to more effectively protect the energy storage component 3 and the charge and discharge control component 4, but also ensures the flatness of the photovoltaic module 2.

[0041] In some implementation methods, please refer to Figures 1 to 4 The power supply device 100 also includes an adhesive 5, which is disposed between the energy storage component 3 and the charge / discharge control component 4 and the surface of the first partition region 14 to fix the energy storage component 3 and the charge / discharge control component 4 within the first partition region 14.

[0042] In this embodiment, an adhesive 5 is used to fix the energy storage component 3 and the charge / discharge control component 4 within the first partition region 14. This not only facilitates installation but also ensures insulation performance, as the adhesive 5 can be an insulating adhesive. For example, the adhesive 5 can be, but is not limited to, silicone rubber, epoxy resin, or polyurethane adhesive, etc., insulating adhesives. In some examples, to further protect the energy storage component 3 and the charge / discharge control component 4, the adhesive 5 can fill the gap between the energy storage component 3 and the charge / discharge control component 4 and the surface of the first partition region 14. Please refer to [reference needed]. Figures 1 to 4 .

[0043] In some embodiments, the energy storage component 3 and the charge / discharge control component 4 can be packaged as a single unit. That is, the energy storage component 3 and the charge / discharge control component 4 can be packaged into a single module first, and then the single module can be fixed into the first partition area 14. In other embodiments, the energy storage component and the charge / discharge control component can be packaged separately, which can be set according to the actual situation, and will not be elaborated here.

[0044] As one implementation method, please refer to Figures 1 to 4 The charge / discharge control component 4 has a first port, a second port, and a third port. The first port is an input port and is connected to the photovoltaic module 2 via a first electrical connection line 61. The second port is a bidirectional input / output port and is connected to the bidirectional input / output port of the energy storage component 3 via a second electrical connection line 62. The third port is an output port and is used as the positive and negative terminals of the entire power supply device 100 for output via a third electrical connection line 63.

[0045] As an example, the energy storage component 3 can be an energy storage battery, and the charge / discharge control component 4 can be a hybrid inverter. It should be noted that the energy storage component and charge / discharge control component in this application are prior art and will not be described in detail here.

[0046] In some embodiments, the power supply device 100 further includes an encapsulation assembly 7, which includes four encapsulation plates 71, wherein two encapsulation plates 71 are arranged opposite to each other and spaced apart in a second direction, and the other two encapsulation plates 71 are arranged opposite to each other and spaced apart in a third direction, with the first direction, the second direction, and the third direction being perpendicular to each other. The four encapsulation plates 71 surround to form an encapsulation cavity, and the photovoltaic module 2 and the frame assembly 1 are fixed inside the encapsulation cavity.

[0047] In this embodiment, the frame component 1, photovoltaic component 2, energy storage component 3, and charge / discharge control component 4 are encapsulated within the encapsulation component 7, which can further protect the above components, extend the service life of the power supply device 100, and make it more aesthetically pleasing.

[0048] As an example, the material of the encapsulation plate 71 can be a metal material such as aluminum or steel, or the material of the encapsulation plate 71 can also be a fiber material such as glass fiber, carbon fiber, or basalt fiber, or the material of the encapsulation plate 71 can also be an engineering plastic such as polyvinyl chloride, polyethylene terephthalate, polytetrafluoroethylene, or aramid.

[0049] In some embodiments, the power supply device 100 can be applied to distributed application scenarios such as balcony photovoltaics. Mounting holes can be provided at the four sides or four corners of the power supply device 100 for subsequent installation and fixing. Alternatively, the mounting structure can be pre-embedded into the frame assembly 1 or the encapsulation assembly 7 for subsequent installation and fixing.

[0050] In some embodiments, the power supply unit 100 can be used as a vehicle-mounted photovoltaic system or an outdoor emergency power source. Please refer to [reference needed]. Figures 5 to 6 To better protect the power supply device 100, the power supply device 100 also includes a housing, which includes a shell 81 and a cover 82, and the shell 81 and the cover 82 are closable. An external interface 811 is provided on the shell 81, and a third port is connected to the external interface 811 of the power supply device 100 via a third electrical connection line 63, serving as the positive and negative terminals for output of the entire power supply device 100. The shell 81 has a receiving cavity 812, with an opening at one end in a first direction, and the cover 82 is used to close the opening. The power supply device 100 includes a power core housed within the receiving cavity 812. The power core includes a frame assembly 1, a photovoltaic module 2, an energy storage module 3, a charge / discharge control assembly 4, and an encapsulation assembly 7, with the photovoltaic module 2 facing the opening.

[0051] As one implementation method, please refer to Figure 6 To prevent the power supply core from coming out of the outer casing, the first direction can be up and down, with the opening of the receiving cavity 812 facing upwards.

[0052] In one implementation, the cover 82 can be separated from the opening of the housing 81. When the photovoltaic module 2 is not needed, the cover 82 can be placed on the housing 81 to shield and protect the photovoltaic module 2 from external impacts, etc. Please refer to [reference needed]. Figure 5 When photovoltaic module 2 is needed, the cover 82 can be removed from the housing 81 and placed under the housing 81. Please refer to [reference needed]. Figure 6 As an example, please refer to Figure 5 and Figure 6 The cover 82 may have a flange 821. The shell 81 is a cuboid shell or a cube shell. The upper and lower dimensions of the shell 81 are the same. The flange 821 can not only snap the cover 82 to the upper end of the shell 81, but also snap the cover 82 to the lower end of the shell 81.

[0053] In some embodiments, at least one encapsulation plate 71 has a threaded hole, and the housing 81 has a through hole, with the through hole and the threaded hole corresponding one-to-one. Please refer to... Figure 5 The power supply device 100 also includes a threaded fastener 9, which passes through the through hole and is threaded to the threaded hole to fix the power supply core in the receiving cavity 812.

[0054] In this embodiment, the power supply core and housing 81 are detachably connected by threaded fasteners 9, which makes assembly and maintenance easier.

[0055] As an example, each package plate 71 has a threaded hole, and correspondingly, the housing 81 has four through holes. The power supply device 100 includes four threaded fasteners 9, which are screws. The screws pass through the corresponding through holes and are screwed into the corresponding threaded holes, thereby securely fixing the power supply core inside the housing 81.

[0056] It should be noted that in other embodiments, the power supply device 100 may also include other numbers of threaded fasteners, which can be set according to the actual situation, and will not be described in detail here.

[0057] In some implementation methods, please refer to Figure 5 and Figure 6 The housing also includes two handles 10, which are symmetrically arranged on both sides of the housing 81 in a second direction, or symmetrically arranged on both sides of the housing 81 in a third direction. Each handle 10 includes a gripping part 101 and two flexible connecting parts 102, which are symmetrically arranged at both ends of the gripping part 101. One end of the flexible connecting part 102 is connected to the gripping part 101, and the other end of the flexible connecting part 102 is connected to the housing 81. The gripping parts 101 of the two handles 10 are detachably connected. Please refer to [reference needed]. Figure 5When the power supply device 100 needs to be moved, the two handles 101 can be connected together. This not only makes it easier for the user to hold the handles 101 and lift the power supply device 100 in a balanced manner, but also allows the two connected handles 10 to provide a certain degree of fixation for the cover 82, pressing the cover 82 against the housing 81. Please refer to... Figure 6 When the photovoltaic module 2 needs to be used, the two holding parts 101 can be separated first, and then the cover 82 can be removed, which is convenient to use.

[0058] As an example, the two gripping parts 101 can be a Velcro structure that is adhesively joined. Alternatively, the two gripping parts 101 can be a magnetic structure that is magnetically joined. Alternatively, the two gripping parts can also be other structures that cooperate with each other, which can be set according to the actual situation, and will not be described in detail here.

[0059] The power system 1000 provided in this application embodiment includes the power supply device 100 provided in any of the above embodiments. There are multiple power supply devices 100, and the multiple power supply devices 100 are electrically connected. For example, please refer to... Figure 7 Multiple power supply devices 100 can be connected in series via the third electrical connection line 63. Alternatively, multiple power supply devices 100 can also be connected in parallel, depending on the actual situation, and no limitation is made here.

[0060] In this embodiment, when multiple power supply devices 100 are connected in series via the third electrical connection line 63, the output voltages of each power supply device 100 can be superimposed to increase the total voltage, which is suitable for scenarios requiring high-voltage power supply, such as high-voltage equipment or long-distance power transmission. Conversely, when multiple power supply devices 100 are connected in parallel, the output currents of each power supply device 100 can be superimposed to increase the total current capacity, which is suitable for scenarios requiring simultaneous power supply to multiple devices or high reliability scenarios requiring fault tolerance. The power system 1000 provided in this application embodiment can flexibly meet the voltage, current, and reliability requirements of different loads.

[0061] The processing method of the power supply device in this application embodiment is used to prepare the power supply device 100 provided in any of the above embodiments.

[0062] The processing method of the power supply device according to the embodiments of this application includes steps S11 to S13: Step S11: Fix the photovoltaic module 2 to the frame assembly 1. The frame assembly 1 has a first plate 11 and a second plate 12 spaced apart in a first direction, and a plurality of partition plates 13 disposed between the first plate 11 and the second plate 12. The partition plates 13 divide the gap between the first plate 11 and the second plate 12 into a plurality of partition areas. The photovoltaic module 2 is fixed to the end of the first plate 11 away from the second plate 12 in the first direction.

[0063] In one embodiment, the photovoltaic module 2 includes an encapsulation layer 21, a first adhesive layer 23, and a solar cell array 22 sequentially stacked in a first direction. Step S11 specifically includes steps S111 to S113: Step S111: The encapsulation layer 21, the first adhesive layer 23, the solar cell array 22, the second adhesive layer 24 and the frame assembly 1 are stacked in sequence to form the first intermediate body.

[0064] Step S112: Place the first intermediate into the laminator and laminate the encapsulation layer 21 facing the heating surface of the laminator.

[0065] Step S113: Trim the edges of the first intermediate after lamination to remove excess adhesive.

[0066] In this embodiment, the photovoltaic module 2 and the frame module 1 are fixed by lamination, making the connection between the two more reliable and improving the structural stability and strength of the power supply device 100. It should be noted that in some embodiments, only the first plate 11 of the frame module 1 can be placed in the laminator for lamination, and the photovoltaic module 2 can be fixed to the first plate 11 before assembling the first plate 11, the second plate 12, and the partition plate 13 into the frame module 1 as a whole. In other embodiments, the first plate 11, the second plate 12, and the partition plate 13 can be assembled into the frame module 1 as a whole first, and then the entire frame module 1 can be placed in the laminator for lamination. This can be configured according to actual conditions and will not be elaborated upon here.

[0067] As an example, the lamination process is divided into a vacuuming stage and a pressurization stage. The vacuuming stage lasts for 300s to 900s, and vacuuming can completely eliminate interlayer air bubbles. The pressurization stage is a gradient pressurization, that is, the pressure is gradually increased. After the last pressurization process, the relative pressure is set to -80kPa to -20kPa, that is, the absolute pressure applied to the photovoltaic module 2 after the last pressurization process is 20kPa to 80kPa. The holding time of the last pressurization process is 10min to 60min, and the lamination temperature is 140℃ to 180℃.

[0068] In some embodiments, the photovoltaic module 2 includes an encapsulation layer 21, a first adhesive layer 23, a solar cell array 22, a third adhesive layer 26, and a backsheet layer 25 sequentially stacked in a first direction, with the backsheet layer 25 facing the frame module 1. Prior to step S11, the power supply device processing method further includes step S14: Step S14, forming photovoltaic module 2.

[0069] In this embodiment, the photovoltaic module 2 is first fabricated and then fixed onto the frame module 1. In other words, the photovoltaic module 2 can be fabricated based on conventional photovoltaic module manufacturing processes, or a frameless commercial photovoltaic module can be directly used as the photovoltaic module 2, making the integration process simpler.

[0070] As an example, step S14 specifically includes steps S141 to S143: Step S141: The encapsulation layer 21, the first adhesive layer 23, the solar cell array 22, the third adhesive layer 26 and the backsheet layer 25 are stacked in sequence to form the second intermediate.

[0071] Step S142: Place the second intermediate into the laminator and laminate the encapsulation layer 21 facing the heating surface of the laminator.

[0072] Step S143: Trim the edges of the second intermediate after lamination.

[0073] Accordingly, step S11 after step S14 includes: applying an adhesive such as silicone rubber, epoxy resin or polyurethane glue to the surface of the first plate 11 facing away from the second plate 12 by scraping or spraying to form a fourth adhesive layer 27, and then bonding the prepared photovoltaic module 2 to the first plate 11 through the fourth adhesive layer 27, and then curing the fourth adhesive layer 27 to fix the photovoltaic module 2 and the frame assembly 1.

[0074] Step S12: Fix the energy storage component 3 and the charge / discharge control component 4 in one of the partition areas.

[0075] In one implementation, the energy storage module 3 and the charge / discharge control module 4 are integrally packaged, that is, the energy storage module 3 and the charge / discharge control module 4 have been electrically connected. Then, the adhesive 5 is directly coated on the outside of the energy storage module 3 and the charge / discharge control module 4. Then, the energy storage module 3 and the charge / discharge control module 4 coated with adhesive 5 are placed in the first partition area 14 of the frame module 1. The photovoltaic module 2 and the charge / discharge control module 4 are then connected by soldering, and the adhesive 5 is cured.

[0076] In one implementation, the energy storage module 3 and the charge / discharge control module 4 are separately packaged. That is, if the energy storage module 3 and the charge / discharge control module 4 are not electrically connected, they are first connected by soldering and then insulated. Then, adhesive 5 is applied to the outside of the energy storage module 3 and the charge / discharge control module 4. The energy storage module 3 and the charge / discharge control module 4 coated with adhesive 5 are then placed in the first partition area 14 of the frame module 1. The photovoltaic module 2 and the charge / discharge control module 4 are then connected by soldering, and the adhesive 5 is cured.

[0077] It is understandable that, in order to achieve the electrical connection between the photovoltaic module 2 and the charge / discharge control component 4, the processing method of the power supply device further includes step S15: making the first electrical connection line 61 connected to the positive and negative terminals of the photovoltaic module 2 pass through the first plate 11 and enter the first partition area 14 to connect with the charge / discharge control component 4.

[0078] Step S13: Fix the encapsulation component 7 to the frame component 1 and the photovoltaic module 2. The encapsulation component 7 includes four encapsulation plates 71, two of which are arranged opposite to each other and spaced apart in the second direction, and the other two are arranged opposite to each other and spaced apart in the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The four encapsulation plates 71 surround to form an encapsulation cavity, and the photovoltaic module 2 and the frame component 1 are housed in the encapsulation cavity.

[0079] As an example, silicone rubber, epoxy resin, or polyurethane adhesive can be used to bond the encapsulation plate 71 to the sides of the photovoltaic module 2 and the frame module 1 to achieve edge sealing. It should be noted that the position of the encapsulation plate 71 corresponding to the third port of the charge / discharge control component 4 should be pre-drilled according to the size of the lead cable, i.e., the third electrical connection line 63. After assembly, only the third electrical connection line 63 connected to the charge / discharge control component 4 serves as the positive and negative terminals of the entire power module for output.

[0080] In some embodiments, after step S13, the processing method of the power supply device further includes step S16: Step S16: Perform surface cleaning and performance testing on the power supply device 100.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
