For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0054] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0055] According to one embodiment of the present disclosure, a kind of energy storage system is provided. Referring to figures 1 to 9, the energy storage system 100 includes body 1, photoelectric conversion layer 2 and radiation refrigeration layer 3, photoelectric conversion layer 2 is arranged in body 1;Radiation refrigeration layer 3 is used to reflect heat energy.

[0056] Specifically, as shown in figure 1, the energy storage system 100 of the embodiment of the present disclosure can be arranged at the position of 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, etc., to effectively improve the energy storage effect of the vehicle, and ensure the heat insulation performance of the passenger compartment of the vehicle. Wherein, the energy storage system 100 can be arranged in the passenger compartment of the vehicle, or when the glass of the vehicle is double glazing, the energy storage system 100 can be arranged between the double glazing.

[0057] The body 1 can be a hard material such as glass, or can be a flexible material such as a curtain cloth. Photoelectric conversion layer 2 is arranged on one side of body 1, and radiation refrigeration layer 3 is arranged on the side of body 1 away from photoelectric conversion layer 2.

[0058] Thus, when the photoelectric conversion layer 2 is irradiated by sunlight, the photoelectric conversion layer 2 can convert the sunlight into electric energy, and then the electric energy generated by the photoelectric conversion layer 2 is transmitted to the energy storage device through the conductive device for storage, thereby significantly improving the energy storage efficiency of the vehicle. Moreover, since the radiation cooling layer 3 of the embodiment of the present disclosure can reflect most of the solar radiation to the cold outer space in the direction of the photoelectric conversion layer 2 to achieve the effect of reducing the surface temperature of the object during the day. Therefore, when the radiation cooling layer 3 is irradiated by sunlight, 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 100 of the present disclosure is arranged 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 of the interior of the vehicle, and also makes the vehicle no longer need to set up an independent sunshade system to improve the heat insulation performance of the passenger compartment, thereby significantly reducing the production cost of the vehicle.

[0059] In addition, the radiation cooling layer 3 of the embodiment of the present disclosure can also not be fixedly arranged on the side of the body 1 away from the photoelectric conversion layer 2, but only needs to achieve the reflection of solar radiation.

[0060] For example, the radiation cooling layer 3 of the embodiment of the present disclosure can be arranged on the side of the photoelectric conversion layer 2 away from the body 1, at this time, the radiation cooling layer 3 is a transparent radiation cooling layer; or the radiation cooling layer 3 can also be independent of the body 1. As shown in FIG. 2, 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 can be arranged on the second glass 8, or the radiation cooling layer 3 can be arranged on both the first glass 7 and the second glass 8.

[0061] When the radiation cooling layer 3 is arranged on the first glass 7, the radiation cooling layer 3 is a transparent radiation cooling layer.

[0062] In addition, the radiation cooling layer 3 in the embodiment of the present disclosure is mainly based on the spectral response characteristics of the radiation cooling material in the mid-infrared wave band to emit heat to the cold outer space through the atmospheric transparent window, while reflecting a large amount of solar radiation heat to achieve the cooling effect.

[0063] In one embodiment, the thickness of the radiation cooling layer 3 ranges from 50 μm to 200 μm.

[0064] Specifically, as shown in FIG. 1, the radiation cooling layer 3 of the embodiment of the present disclosure is arranged on the side of the body 1 away from the photoelectric conversion layer 2.

[0065] However, when the radiation cooling layer 3 is too thick, the uniformity of the radiation cooling layer 3 is poor, which affects the radiation cooling effect of the radiation cooling layer 3. In addition, the over-thick coating layer will generate cracks during the drying or curing process, which will affect the continuity and radiation cooling effect of the radiation cooling layer 3. Therefore, in order to ensure that the radiation cooling layer 3 has a good radiation cooling effect, the thickness of the radiation cooling layer 3 is preferably not more than 200 μm. When the radiation cooling layer 3 is too thin, the radiation cooling layer 3 cannot completely cover the glass of the vehicle, which causes sunlight to easily pass through the glass and enter the vehicle cabin, affecting the heat insulation effect of the vehicle interior. In addition, the thin radiation cooling layer 3 is also easily affected by weathering and mechanical wear and tear and gradually disappears, which seriously affects the heat insulation effect of the vehicle interior. Therefore, in order to ensure that the radiation cooling layer 3 has a good radiation cooling effect, the thickness of the radiation cooling layer 3 is preferably not less than 50 μm.

[0066] In addition, by setting the thickness of the radiation cooling layer 3 to be 50-200 μm, the radiation cooling layer 3 effectively improves the absorption and emission rates of infrared radiation, and significantly enhances the heat insulation performance of the glass assembly.

[0067] In one embodiment, the material of the radiation 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.

[0068] Specifically, by setting the material of the radiation 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 100 is effectively reduced.

[0069] Of course, the radiation cooling layer 3 can also be made of other materials in the present disclosure, as long as it can reflect a large amount of solar radiation heat to achieve the cooling effect. Those skilled in the art can select according to actual needs, and the present disclosure does not make specific limitations here.

[0070] In one embodiment, the radiation cooling layer 3 is arranged on the body 1, and the radiation cooling layer 3 is a radiation cooling coating sprayed on the surface of the body 1.

[0071] Specifically, as shown in FIG. 1, since the photoelectric conversion layer 2 of the present disclosure can be fixedly arranged on one side of the body 1, the radiation cooling layer 3 is arranged on the side of the body 1 away from the photoelectric conversion layer 2, so that the body 1, the photoelectric conversion layer 2 and the radiation cooling layer 3 form an integrated structure, which effectively simplifies the installation difficulty of the radiation cooling layer 3.

[0072] In addition, by setting the radiation cooling layer 3 as a radiation cooling coating, the present disclosure effectively simplifies the setting difficulty of the radiation cooling layer 3.

[0073] For example, after the radiation cooling layer 3 is gradually thinned due to weathering and mechanical wear and tear, the radiation cooling material can be sprayed directly onto the surface of the body 1 to form the radiation cooling layer 3, thereby effectively improving the assembly efficiency of the radiation cooling layer 3 and significantly reducing the maintenance cost of the energy storage system 100.

[0074] In one embodiment, the radiation cooling layer 3 is independent of the body 1, and the radiation cooling layer 3 is spaced apart from the photoelectric conversion layer 2 along the first direction.

[0075] Specifically, as shown in FIG. 2, the radiation cooling layer 3 of the embodiment of the present disclosure can be provided on the first glass 7, or can be provided on the second glass 8, or the radiation cooling layer 3 can be provided on both the first glass 7 and the second glass 8. At this time, after the body 1 is wound by the winding device, the radiation cooling layer 3 can also ensure the heat insulation effect of the vehicle interior, effectively avoiding the problem that the radiation cooling layer 3 is wound by the winding device with the body 1, resulting in poor heat insulation effect of the vehicle interior.

[0076] It should be noted that the first direction of the embodiment of the present disclosure is the height direction of the body 1, or the height direction of the first glass 7 and the second glass 8.

[0077] In one embodiment, the thickness of the photoelectric conversion layer 2 ranges from 10 μm to 500 μm.

[0078] Specifically, as shown in FIGS. 1 and 4, by setting the thickness of the photoelectric conversion layer 2 to range from 10 μm to 500 μm, not only is the flexible transition of the photoelectric conversion layer 2 retained, so that the photoelectric conversion layer 2 can bend 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.

[0079] The material of the photoelectric conversion layer 2 of the embodiment of the present disclosure can be at least one of a nano coating, a fluorine material, polyethylene terephthalate, an anti-reflection coating, an organic silicon compound, or titanium dioxide. Those skilled in the art can select according to actual needs, which is not specifically limited in the present disclosure.

[0080] In one embodiment, the photoelectric conversion layer 2 is provided in a plurality, and the plurality of photoelectric conversion layers 2 are spaced apart along the second direction of the body 1.

[0081] Specifically, as shown in FIGS. 5 and 6, by spacing the plurality of photoelectric conversion layers 2 along the second direction of the body 1, the straight edge of the photoelectric conversion layer 2 can cooperate with the arc-shaped structure of the winding device 10 when the body 1 is wound by the winding device 10, thereby effectively improving the compactness of the photoelectric conversion layer 2 after being wound.

[0082] It should be noted that the second direction of the embodiment of the present disclosure is the length direction of the body 1, or the winding direction of the body 1 by the winding device 10, and the second direction and the first direction are two intersecting directions.

[0083] In one embodiment, each photoelectric conversion layer 2 is in a strip shape.

[0084] Specifically, as shown in FIGS. 5 and 6, the embodiment of the present disclosure can make the photoelectric conversion layer 2 better contact with the body 1 by setting the photoelectric conversion layer 2 in a strip shape, so as to avoid affecting the service life of the photoelectric conversion layer 2 due to vibration when the body 1 is wound, effectively improve the anti-vibration effect of the photoelectric conversion layer 2, and the strip-shaped photoelectric conversion layer 2 can also be better connected with the body 1 of flexible material, so as to significantly improve the use effect of the photoelectric conversion layer 2.

[0085] In addition, the photoelectric conversion layer 2 of the embodiment of the present disclosure can also be in a plate shape or a grid shape or other shapes. Those skilled in the art can select according to actual needs, and the present disclosure does not make specific limitations here.

[0086] In one embodiment, in the second direction, the width of the photoelectric conversion layer 2 ranges from 20 mm to 50 mm, and the gap between the adjacent two photoelectric conversion layers 2 ranges from 2 mm to 5 mm.

[0087] Specifically, as shown in FIGS. 4 to 6, the width direction of the photoelectric conversion layer 2 of the embodiment of the present disclosure is the length direction of the body 1, or the winding direction of the body 1 by the winding device 10; the length direction of the photoelectric conversion layer 2 is the width direction of the body 1, or the axis direction of the winding device 10.

[0088] Therefore, the embodiment of the present disclosure sets the gap between the adjacent two photoelectric conversion layers 2 to range from 2 mm to 5 mm, so that 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 10, thereby effectively improving the compactness of the photoelectric conversion layer 2 after being wound.

[0089] In addition, the embodiment of the present disclosure also sets the width of the photoelectric conversion layer 2 to range from 20 mm to 50 mm, thereby effectively improving the photoelectric conversion performance of the photoelectric conversion layer 2 and significantly enhancing the energy storage performance of the glass assembly.

[0090] In one embodiment, the photoelectric conversion layer 2 is a photovoltaic coating sprayed on the surface of the body 1.

[0091] Specifically, the present disclosure sets the photoelectric conversion layer 2 as a photovoltaic coating, thereby effectively simplifying the setting difficulty of the photoelectric conversion layer 2.

[0092] For example, after the photoelectric conversion layer 2 is gradually thinned due to weathering and mechanical wear and tear, the photoelectric conversion material can be sprayed onto the surface of the body 1 by using 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 100.

[0093] In one embodiment, the body 1 is a flexible body.

[0094] Specifically, the body 1 can be a flexible body made of linen, cotton, flannel, pure cotton, cashmere, polyester fiber, or the like, so that the body 1 can be wound by the winding device 10, thereby effectively improving the ventilation effect of the vehicle.

[0095] In addition, by setting the body 1 as a flexible body, the existing glass material is abandoned, so that the photoelectric conversion layer 2 can be unfolded or wound with the body 1, thereby greatly meeting the layout requirements of the head space of the whole vehicle.

[0096] In one embodiment, the energy storage system 100 further comprises a conductive layer 4, which is arranged between the photoelectric conversion layer 2 and the body 1.

[0097] Specifically, as shown in FIG. 1, the conductive layer 4 is used to transmit the electrical energy after the photoelectric conversion of the photoelectric conversion layer 2 to the battery or the battery system of the vehicle, so as to ensure the energy storage effect of the glass assembly.

[0098] In one embodiment, the energy storage system 100 further comprises a conductive layer 4, which is arranged between the photoelectric conversion layer 2 and the body 1.

[0099] In one embodiment, the energy storage system 100 further comprises a reflective layer 5, a transparent layer 6, and a conductive layer 4, the reflective layer 5 is arranged on the side of the photoelectric conversion layer 2 close to the body 1, the transparent layer 6 is arranged on the side of the photoelectric conversion layer 2 away from the body 1, and the conductive layer 4 is arranged between the photoelectric conversion layer 2 and the reflective layer 5.

[0100] Specifically, as shown in FIG. 1, the photoelectric conversion layer 2 is encapsulated between the reflective layer 5 and the transparent layer 6, so that the encapsulated photoelectric conversion layer 2 has excellent rigidity and toughness, thereby effectively meeting the subsequent winding fixation of the photoelectric conversion layer 2. In addition, by arranging the reflective layer 5 and the transparent layer 6, the mechanical properties, system vibration durability, and fatigue life of the photoelectric conversion layer 2 after winding and unfolding are further ensured.

[0101] In addition, the material of the reflective layer 5 can be at least one of a polymer film, a PC material film, or a metal film. When the reflective layer 5 is a metal film, the thickness of the metal film is preferably in a range of 100-300 μm, so as to significantly enhance the light-shielding performance of the glass assembly.

[0102] In addition, the material of the transparent layer 6 can be at least one of glass, a polyester material, an ethylene-tetrafluoroethylene copolymer, a fluoroplastic, an organic semiconductor material, a transparent conductive oxide, a transparent silicon wafer, a semi-transparent perovskite material, a co-extruded polyester, or an ultraviolet-resistant coating, which can be selected by those skilled in the art according to actual needs, and the present disclosure does not make specific limitations here.

[0103] Of course, the material of the reflective layer 5 can also be the same as the material of the transparent layer 6, which can be selected by those skilled in the art according to actual needs, and the present disclosure does not make specific limitations here.

[0104] In one embodiment, the conductive layer 4 is a transparent crystalline silicon film layer.

[0105] Specifically, since the transparent crystalline silicon film layer has high photoelectric conversion efficiency, transparency, bendability, nonlinear optical properties, and plasmonic optical properties, the use performance of the photoelectric conversion layer 2 can be significantly enhanced, so as to further enhance the energy storage effect of the glass assembly.

[0106] According to another embodiment of the present disclosure, a glass assembly 200 is provided. The glass assembly 200 includes the energy storage system 100 according to the embodiments of the present disclosure, a first glass 7 and a second glass 8, the first glass 7 and the second glass 8 being spaced apart along a direction perpendicular to the body 1 to form a containing space 9; the body 1 is arranged in the containing space 9, the photoelectric conversion layer 2 is arranged on a side of the body 1 facing the first glass 7; the radiation cooling layer 3 is arranged on the body 1, and the radiation cooling layer 3 is a radiation cooling coating sprayed on the surface of the body 1; and / or, the radiation cooling layer 3 is independent of the body 1, and the radiation cooling layer 3 is spaced apart from the body 1 along a direction perpendicular to the body 1.

[0107] Specifically, the glass assembly 200 according to the embodiments of the present disclosure can be arranged at a front side window glass, a rear side window glass, a quarter window glass, a front windshield pillar glass, a rear windshield pillar glass, or a sunroof glass of a 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.

[0108] The embodiments of the present disclosure take the first glass 7 and the second glass 8 as examples of the sunroof glass of the vehicle.

[0109] As shown in FIGS. 2-4, the first glass 7 and the second glass 8 of the embodiment of the present disclosure are spaced apart in a direction perpendicular to the body 1 to form an accommodating space 9 between the first glass 7 and the second glass 8, and the body 1 can be arranged in the accommodating space 9. The body 1 comprises the photoelectric conversion layer 2 arranged on a side of the body 1 facing the first glass 7.

[0110] Therefore, when the vehicle is parked in a lighted place or when the vehicle is running in a lighted place, the photoelectric conversion layer 2 can convert sunlight into electrical energy, and then the electrical energy generated by the photoelectric conversion layer 2 is transmitted to the energy storage device through the conductive device for storage, thereby effectively improving the energy storage efficiency of the vehicle.

[0111] Further, since the body 1 of the embodiment of the present disclosure is provided with the radiation cooling layer 3, and / or the radiation cooling layer 3 is independent of the body 1 and is spaced apart from the body 1 in a direction perpendicular to the body 1. For example, as shown in FIG. 2, the radiation cooling layer 3 can be arranged on a side of the second glass 8 facing the body 1. Therefore, by arranging the radiation cooling layer 3, the embodiment of the present disclosure can reflect the solar radiation irradiated on each glass of the vehicle, thereby effectively reducing the temperature inside the vehicle, ensuring the heat insulation effect inside the vehicle, and also eliminating the need for the vehicle to arrange an independent sunshade system to improve the heat insulation performance of the passenger compartment, thereby significantly reducing the production cost of the vehicle.

[0112] In addition, the first glass 7 and the second glass 8 of the embodiment of the present disclosure can be tempered glass or other materials with good light transmission and strong weather resistance, so as to effectively enhance the stability and reliability of the glass assembly 200. The body 1 can be a hard material such as glass, or can be a flexible material such as a curtain cloth, which can be selected by those skilled in the art according to actual needs, and the present disclosure does not make specific limitations here.

[0113] In one embodiment, the radiation cooling layer 3 is arranged on the second glass 8 and faces the body 1.

[0114] Specifically, as shown in FIGS. 2 and 3, the radiation cooling layer 3 of the embodiment of the present disclosure is arranged on the second glass 8 and located on a side of the second glass 8 facing the body 1, so that after the body 1 is wound by the winding device 10, the heat insulation effect inside the vehicle can also be ensured by the radiation cooling layer 3, thereby effectively avoiding the problem that the radiation cooling layer 3 is wound together with the body 1 by the winding device 10, resulting in poor heat insulation effect inside the vehicle.

[0115] In one embodiment, the radiation cooling layer 3 is a radiation cooling coating sprayed on the surface of the second glass 8.
