[0061] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0063] According to one embodiment of the present application, an energy storage system is provided. Figures 1 to 9 The energy storage system includes a main body 1, a photoelectric conversion layer 2 and a radiation cooling layer 3, wherein the photoelectric conversion layer 2 is arranged on the main body 1; and the radiation cooling layer 3 is used for reflecting heat energy.

[0064] Specifically, if Figure 1 As shown, the energy storage system of the embodiment of the present application can be arranged at the front side window glass, rear side window glass, quarter window glass, front windshield pillar glass, rear windshield pillar glass or sunroof glass of the vehicle, so as to effectively improve the energy storage effect of the vehicle and ensure the heat insulation performance of the passenger compartment of the vehicle. The energy storage system can be arranged in the passenger compartment of the vehicle, or when the glass of the vehicle is double-layer glass, the energy storage system can be arranged between the double-layer glass.

[0065] The body 1 may be made of a hard material such as glass, or a flexible material such as a curtain. The photoelectric conversion layer 2 is arranged on one side of the body 1 , and the radiation cooling layer 3 is arranged on a side of the body 1 away from the photoelectric conversion layer 2 .

[0066] Thus, when sunlight irradiates the photoelectric conversion layer 2, the photoelectric conversion layer 2 can convert sunlight into electrical energy, and then transmit the electrical energy converted by the photoelectric conversion layer 2 to the energy storage device for storage through the conductive device, thereby significantly improving the energy storage efficiency of the vehicle. Moreover, since the radiation cooling layer 3 in the embodiment of the present application can reflect most of the solar radiation to the cold outer space in the direction of the photoelectric conversion layer 2, thereby achieving the effect of lowering the surface temperature of the object during the day, when sunlight irradiates the radiation cooling layer 3, the radiation cooling layer 3 can effectively reduce the temperature on the side of the radiation cooling layer 3 away from the photoelectric conversion layer 2, that is, when the energy storage system of the present application is set on each glass of the vehicle, the radiation cooling layer 3 can reflect the solar radiation irradiated to each glass of the vehicle, thereby effectively ensuring the heat insulation effect inside the vehicle, and also making it unnecessary for the vehicle to set up an independent sunshade system to improve the heat insulation performance of the passenger compartment, significantly reducing the production cost of the vehicle.

[0067] In addition, the radiation cooling layer 3 in the embodiment of the present application may not be fixedly arranged on the side of the body 1 away from the photoelectric conversion layer 2, and only needs to reflect solar radiation.

[0068] For example, the radiation cooling layer 3 in the embodiment of the present application can be arranged on the side of the photoelectric conversion layer 2 away from the main body 1. In this case, the radiation cooling layer 3 is a transparent radiation cooling layer; or, the radiation cooling layer 3 can also be independent of the main body 1, such as Figure 2 As shown, the first glass 7 is arranged on the outside of the vehicle, and the second glass 8 is arranged on the inside of the vehicle. At this time, the radiation cooling layer 3 can be arranged on the first glass 7, or on the second glass 8, or on both the first glass 7 and the second glass 8.

[0069] Wherein, when the radiation cooling layer 3 is disposed on the first glass 7 , the radiation cooling layer 3 is a transparent radiation cooling layer.

[0070] In addition, the radiation cooling layer 3 in the embodiment of the present application is mainly based on the spectral response characteristics of the radiation cooling material in the mid-infrared band, so as to emit heat into the cold outer space through the atmospheric transparent window, while reflecting a large amount of solar radiation heat to achieve a cooling effect.

[0071] In one embodiment, the thickness of the radiation cooling layer 3 is in the range of 50 to 200 μm.

[0072] Specifically, if Figure 1 As shown, the radiation cooling layer 3 in the embodiment of the present application is arranged on a side of the body 1 away from the photoelectric conversion layer 2 .

[0073] Therefore, when the radiative cooling layer 3 is too thick, the uniformity of the radiative cooling layer 3 will be poor, which will further affect the radiative cooling effect of the radiative cooling layer 3. Moreover, since the too thick coating will also generate cracks during the drying or curing process, resulting in poor continuity and radiative cooling effect of the radiative cooling layer 3. Therefore, in order to ensure that the radiative cooling layer 3 has a good radiative cooling effect, it is preferably that the thickness of the radiative cooling layer 3 does not exceed 200 μm. When the radiative cooling layer 3 is too thin, the radiative cooling layer 3 cannot completely cover the glass of the vehicle, resulting in sunlight easily passing through the glass and entering the vehicle passenger compartment, affecting the heat insulation effect inside the vehicle. Moreover, the too thin radiative cooling layer 3 is also easily affected by weathering and mechanical wear and gradually disappears, which will seriously affect the heat insulation effect inside the vehicle. Therefore, in order to ensure that the radiative cooling layer 3 has a good radiative cooling effect, it is preferably that the thickness of the radiative cooling layer 3 is not less than 50 μm.

[0074] In addition, in the embodiment of the present application, by setting the thickness range of the radiative cooling layer 3 to be 50-200 μm, the absorption rate and emissivity of the radiative cooling layer 3 for infrared radiation are effectively improved, and the heat insulation performance of the glass assembly is significantly enhanced.

[0075] In one embodiment, the material of the radiative cooling layer 3 includes at least one of aluminum oxide, silicon dioxide, polyvinylidene fluoride-hexafluoropropylene, barium sulfate super white paint, and polymer film-metal thermal emitter.

[0076] Specifically, in the embodiment of the present application, by setting the material of the radiative cooling layer 3 to be at least one of aluminum oxide, silicon dioxide, polyvinylidene fluoride-hexafluoropropylene, barium sulfate super white paint, and polymer film-metal thermal emitter, the manufacturing cost of the energy storage system is effectively reduced.

[0077] Of course, in the embodiment of the present application, other materials can also be selected to prepare the radiative cooling layer 3, as long as it can reflect a large amount of solar radiation heat to achieve a cooling effect. Those skilled in the art can choose according to actual needs, and the present application does not make specific limitations here.

[0078] In one embodiment, the radiative cooling layer 3 is provided on the body 1, and the radiative cooling layer 3 is a radiative cooling coating sprayed on the surface of the body 1.

[0079] Specifically, as Figure 1 shown, since the photoelectric conversion layer 2 in the embodiment of the present application can be fixedly provided on one side of the body 1, by providing the radiative cooling layer 3 on the side of the body 1 facing away from the photoelectric conversion layer 2, the body 1, the photoelectric conversion layer 2, and the radiative cooling layer 3 can form an integral structure, thereby effectively simplifying the installation difficulty of the radiative cooling layer 3.

[0080] In addition, by setting the radiative cooling layer 3 as a radiative cooling coating in the present application, the difficulty of setting the radiative cooling layer 3 is effectively simplified.

[0081] For example, after the radiative cooling layer 3 gradually becomes thinner due to weathering and mechanical wear, the radiative cooling material can be directly sprayed onto the surface of the body 1 by a spraying device to form the radiative cooling layer 3, thereby effectively improving the assembly efficiency of the radiative cooling layer 3 and significantly reducing the maintenance cost of the energy storage system.

[0082] In one embodiment, the radiative cooling layer 3 is independent of the body 1, and the radiative cooling layer 3 is spaced apart from the photoelectric conversion layer 2 in a first direction.

[0083] Specifically, as Figure 2 shown, the radiative cooling layer 3 in the embodiment of the present application can be disposed on the first glass 7, or can be disposed on the second glass 8, or the radiative cooling layer 3 can also be disposed on both the first glass 7 and the second glass 8 at the same time. At this time, after the body 1 is wound up by a winding device, the radiative cooling layer 3 can also be used to ensure the heat insulation effect inside the vehicle, effectively avoiding the problem that the heat insulation effect inside the vehicle is poor after the radiative cooling layer 3 is wound up by the winding device together with the body 1.

[0084] It should be noted that the first direction in the embodiment of the present application is the height direction of the body 1, or the height direction of the first glass 7 and the second glass 8.

[0085] In one embodiment, the thickness range of the photoelectric conversion layer 2 is 10 - 500 μm.

[0086] Specifically, as Figure 1 and Figure 4 shown, by setting the thickness range of the photoelectric conversion layer 2 to be 10 - 500 μm in the embodiment of the present application, not only the flexible transition of the photoelectric conversion layer 2 is retained, enabling the photoelectric conversion layer 2 to bend along with the body 1, but also the photoelectric conversion layer 2 has good photoelectric conversion performance, significantly enhancing the energy storage performance of the glass assembly.

[0087] Among them, the material of the photoelectric conversion layer 2 in the embodiment of the present application can be at least one of a nano - coating, a fluorine material, polyethylene terephthalate, an antireflection coating, an organosilicon compound, or titanium dioxide. Those skilled in the art can select according to actual needs, and the present application does not make specific limitations here.

[0088] In one embodiment, a plurality of the photo - electric conversion layers 2 are provided, and the plurality of photo - electric conversion layers 2 are arranged at intervals along the second direction of the body 1.

[0089] Specifically, as Figure 5 and Figure 6 shown, in the embodiment of the present application, by arranging the plurality of photo - electric conversion layers 2 at intervals along the second direction of the body 1, when the body 1 is wound by the winding device 10, the straight edges of the photo - electric conversion layers 2 can cooperate with the arc - shaped structure of the winding device 10, thereby effectively improving the compactness of the photo - electric conversion layers 2 after being wound.

[0090] It should be noted that in the embodiment of the present application, the second direction is the length direction of the body 1 or the winding direction of the body 1 when the body 1 is wound by the winding device 10, and the second direction and the first direction are two intersecting directions.

[0091] In one embodiment, each of the photo - electric conversion layers 2 is strip - shaped.

[0092] Specifically, as Figure 5 and Figure 6 shown, in the embodiment of the present application, by setting the photo - electric conversion layer 2 as strip - shaped, the photo - electric conversion layer 2 can better contact with the body 1, so as to avoid affecting the service life of the photo - electric conversion layer 2 due to vibration when the body 1 is wound, effectively improving the anti - vibration effect of the photo - electric conversion layer 2. Moreover, the strip - shaped photo - electric conversion layer 2 can also better connect with the flexible - material body 1, thereby significantly improving the use effect of the photo - electric conversion layer 2.

[0093] In addition, the photo - electric conversion layer 2 in the embodiment of the present application can also be in other shapes such as plate - shaped or grid - shaped, etc. Those skilled in the art can select according to actual needs, and the present application does not make specific limitations here.

[0094] In one embodiment, in the second direction, the width range of the photo - electric conversion layer 2 is 20 - 50 mm, and the gap range between two adjacent photo - electric conversion layers 2 is 2 - 5 mm.

[0095] Specifically, as Figures 4 to 6 shown, in the embodiment of the present application, the width direction of the photo - electric conversion layer 2 is the length direction of the body 1 or the winding direction of the body 1 when the body 1 is wound by the winding device 10; the length direction of the photo - electric conversion layer 2 is the width direction of the body 1 or the axis direction of the winding device 10.

[0096] Thus, in the embodiment of the present application, by setting the gap range between two adjacent pieces of the photoelectric conversion layer 2 to be 2-5 mm, when the photoelectric conversion layer 2 is wound by the winding device 10, the straight edge of the photoelectric conversion layer 2 can be matched with the arc-shaped structure of the winding device, thereby effectively improving the compactness of the wound photoelectric conversion layer 2.

[0097] In addition, in the embodiment of the present application, by setting the width range of the photoelectric conversion layer 2 to be 20-50 mm, the photoelectric conversion performance of the photoelectric conversion layer 2 is effectively improved, and the energy storage performance of the glass assembly is significantly enhanced.

[0098] In one embodiment, the photoelectric conversion layer 2 is a photovoltaic coating sprayed on the surface of the body.

[0099] Specifically, by setting the photoelectric conversion layer 2 as a photovoltaic coating in the present application, the setting difficulty of the photoelectric conversion layer 2 is effectively simplified.

[0100] For example, after the photoelectric conversion layer 2 is gradually thinned due to weathering and mechanical wear, the photoelectric conversion material can be directly sprayed onto the surface of the body 1 by a spraying device to form the photoelectric conversion layer 2, thereby effectively improving the assembly efficiency of the photoelectric conversion layer 2 and significantly reducing the maintenance cost of the energy storage system.

[0101] In one embodiment, the body 1 is a flexible body.

[0102] Specifically, the body 1 in the embodiment of the present application can be a flexible body made of materials such as linen, cotton linen, flannelette, pure cotton, chenille or polyester fiber, so that the body 1 can be wound by the winding device 10, effectively improving the ventilation effect of the vehicle.

[0103] In addition, by setting the body 1 as a flexible body in the embodiment of the present application, the existing glass material is also discarded, so that the photoelectric conversion layer 2 can be unfolded or wound along with the body 1, greatly meeting the demanding headspace layout requirements of the whole vehicle.

[0104] In one embodiment, the energy storage system further includes a first conductive layer 4, and the first conductive layer 4 is disposed between the photoelectric conversion layer 2 and the body 1.

[0105] Specifically, as Figure 1 shown, the first conductive layer 4 in the embodiment of the present application is used to deliver the electric energy converted by the photoelectric conversion layer 2 to a storage battery or the battery system of the vehicle to ensure the energy storage effect of the glass assembly.

[0106] Among them, the embodiment of the present application arranges the first conductive layer 4 between the photoelectric conversion layer 2 and the main body 1 so that the first conductive layer 4 can be rolled up by the rolling device together with the main body 1, thereby effectively improving the rolling feasibility of the energy storage system.

[0107] In one embodiment, the energy storage system further includes a reflective layer 5, a transparent layer 6 and a first conductive layer 4, wherein the reflective layer 5 is arranged on a side of the photoelectric conversion layer 2 close to the main body 1, the transparent layer 6 is arranged on a side of the photoelectric conversion layer 2 away from the main body 1, and the first conductive layer 4 is arranged between the photoelectric conversion layer 2 and the reflective layer 5.

[0108] Specifically, if Figure 1 As shown, the embodiment of the present application encapsulates the photoelectric conversion layer 2 between the reflective layer 5 and the transparent layer 6, so that the encapsulated photoelectric conversion layer 2 has excellent rigidity and toughness, so as to effectively meet the subsequent rolling and fixing of the photoelectric conversion layer 2. In addition, the embodiment of the present application further ensures the mechanical properties, system vibration durability and fatigue life of the photoelectric conversion layer 2 after rolling and unfolding through the arrangement of the reflective layer 5 and the transparent layer 6.

[0109] In addition, the material of the reflective layer 5 in the embodiment of the present application can be at least one of a polymer film, a PC material film or a metal film. When the light-emitting layer is the metal film, the thickness of the metal film is preferably in the range of 100 to 300 μm to significantly enhance the light-shielding performance of the glass assembly.

[0110] In addition, the material of the transparent layer 6 described in the embodiment of the present application can be at least one of glass, polyester material, ethylene-tetrafluoroethylene copolymer, fluoroplastic, organic semiconductor material, transparent conductive oxide, transparent silicon wafer, semi-transparent perovskite material, co-extruded polyester or anti-ultraviolet coating. Those skilled in the art can choose according to actual needs, and the present application does not make any specific restrictions here.

[0111] Of course, the material of the reflective layer 5 described in the embodiment of the present application can also be the same as the material of the transparent layer 6. Those skilled in the art can choose according to actual needs, and the present application does not make any specific restrictions here.

[0112] In one embodiment, the first conductive layer 4 is a transparent crystalline silicon film layer.

[0113] Specifically, since the transparent crystalline silicon film layer has high photoelectric conversion efficiency, transparency, flexibility, nonlinear optical properties and plasma optical properties, it can significantly enhance the performance of the photoelectric conversion layer 2, thereby further enhancing the energy storage effect of the glass assembly.

[0114] According to another embodiment of the present application, a glass assembly is provided. The glass assembly includes an energy storage system, a first glass 7, and a second glass 8 as described in the embodiments of the present application. The first glass 7 and the second glass 8 are spaced apart in a direction perpendicular to the body 1 to form an accommodation space 9. The body 1 is disposed in the accommodation space 9, and the photoelectric conversion layer 2 is disposed on a side of the body 1 facing the first glass 7. The radiative cooling layer 3 is disposed on the body 1, and the radiative cooling layer 3 is a radiative cooling coating sprayed on the surface of the body 1; and / or, the radiative cooling layer 3 is independent of the body 1, and the radiative cooling layer 3 is spaced apart from the body 1 in a direction perpendicular to the body 1.

[0115] Specifically, the glass assembly described in the embodiments of the present application can be disposed at positions such as the front side window glass, the rear side window glass, the quarter window glass, the front windshield pillar glass, the rear windshield pillar glass, or the sunroof glass of a vehicle to effectively improve the energy storage effect of the vehicle and ensure the heat insulation performance of the vehicle occupant compartment.

[0116] The embodiments of the present application will be described by taking the first glass 7 and the second glass 8 as the sunroof glass of the vehicle as an example.

[0117] As Figures 2 to 4 shown, the first glass 7 and the second glass 8 described in the embodiments of the present application are spaced apart in a direction perpendicular to the body 1 to form the accommodation space 9 between the first glass 7 and the second glass 8, and the body 1 can be disposed in the accommodation space 9. The body 1 includes a photoelectric conversion layer 2, and the photoelectric conversion layer 2 is disposed on a side of the body 1 facing the first glass 7.

[0118] Thus, when the vehicle is parked in a place with sunlight or when the vehicle is traveling in a place with sunlight, the photoelectric conversion layer 2 can convert sunlight into electric energy, and then transmit the electric energy generated by the photoelectric conversion layer 2 to the energy storage device through a conductive device for storage, effectively improving the energy storage efficiency of the vehicle.

[0119] Furthermore, since the body 1 described in the embodiments of the present application is provided with the radiative cooling layer 3; and / or, the radiative cooling layer 3 is independent of the body 1, and the radiative cooling layer 3 is spaced apart from the body 1 in a direction perpendicular to the body 1, for example Figure 2As shown, the radiative cooling layer 3 can be disposed on the side of the second glass 8 facing the body 1. Therefore, in the embodiment of the present application, by providing the radiative cooling layer 3, the solar radiation irradiated on each glass of the vehicle can be reflected, effectively reducing the temperature inside the vehicle, ensuring the heat insulation effect inside the vehicle, and further enabling the vehicle to no longer require a separate sunshade system to improve the heat insulation performance of the passenger compartment, significantly reducing the production cost of the vehicle.

[0120] In addition, in the embodiment of the present application, the first glass 7 and the second glass 8 can be tempered glass or other materials with good light transmittance and strong weather resistance to effectively enhance the stability and reliability of the glass assembly.

[0122] Specifically, as Figure 2 and Figure 3 shown, in the embodiment of the present application, the radiative cooling layer 3 is disposed on the second glass 8 and is located on the side of the second glass 8 facing the body 1, so that after the body 1 is wound up by the winding device, the heat insulation effect inside the vehicle can still be ensured through the radiative cooling layer 3, effectively avoiding the problem that the heat insulation effect inside the vehicle is poor after the radiative cooling layer 3 is wound up by the winding device along with the body 1.

[0123] In one embodiment, the radiative cooling layer 3 is a radiative cooling coating sprayed on the surface of the second glass 8.
