Detailed Implementation

[0073] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0074] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0075] The following reference Figures 1 to 6 This application describes a home energy storage module and a home according to some embodiments.

[0076] like Figure 1 and Figure 2 As shown, the home energy storage module 901 provided in the first aspect embodiment of this application includes: a photovoltaic unit 10, a support unit 20, and a battery energy storage unit 30. The photovoltaic unit 10 has a light-receiving side 101; the support unit 20 is disposed on the side of the photovoltaic unit 10 away from the light-receiving side 101, and the support unit 20 is provided with a mounting cavity 201; the battery energy storage unit 30 is disposed in the mounting cavity 201, and a heat dissipation gap 202 is provided between the battery energy storage unit 30 and the inner wall 2011 of the mounting cavity 201 near the photovoltaic unit 10, and the battery energy storage unit 30 is coupled to the photovoltaic unit 10; wherein, the support unit 20 is provided with a heat dissipation port 203, and the heat dissipation port 203 is connected to the heat dissipation gap 202.

[0077] In the above embodiment, the house energy storage module 901 includes a photovoltaic unit 10, a support unit 20, and a battery energy storage unit 30. The photovoltaic unit 10 is disposed on the support unit 20, and the battery energy storage unit 30 is disposed in the mounting cavity 201 of the support unit 20. The battery energy storage unit 30 is coupled to the photovoltaic unit 10. The photovoltaic unit 10 has a light-receiving side 101 for receiving solar energy. The photovoltaic unit 10 can convert solar energy into electrical energy and transfer it to the battery energy storage unit 30 for storage. There is a heat dissipation gap 202 between the battery energy storage unit and the inner wall 2011 of the mounting cavity 201 near the photovoltaic unit 10. The support unit 20 is provided with a heat dissipation vent 203, which is connected to the heat dissipation gap 202. The heat dissipation gap 202 is used to form a heat dissipation duct, so that both the photovoltaic unit 10 and the battery energy storage unit 30 can dissipate heat to ensure that both the photovoltaic unit 10 and the battery energy storage unit 30 can operate at the specified temperature.

[0078] It is understandable that the heat generated by the photovoltaic section 10 and the battery energy storage section 30 will be transferred to the support section 20. Since the support section 20 is exposed to the external environment over a large area, the heat dissipation effect can be further improved.

[0079] The embodiments of the first aspect described above have the following beneficial effects: Both the photovoltaic device and the battery energy storage device generate heat during operation. The photovoltaic panel's heating up reduces its thermal efficiency, while the battery energy storage device also generates heat during charging and discharging and needs to release it. Maintaining separate heat dissipation systems for each device would be costly. This embodiment of the present disclosure provides a mounting cavity 201 structure for the support portion 20. The photovoltaic portion 10 is placed against the support portion 20 outside of it. The battery energy storage portion 30 is positioned within the mounting cavity 201, separated from the inner wall 2011 of the support portion 20 near the photovoltaic portion 10 by a distance, i.e., a heat dissipation interval 202. This heat dissipation interval 202 is adjacent to the battery energy storage portion 30, allowing it to dissipate heat, and is also separated from the photovoltaic portion 10 only by the inner wall 2011 of the support portion 20. The photovoltaic portion 10 can also dissipate heat to the heat dissipation interval 202 through this inner wall 2011. The heat dissipation gap 202 is connected to the outside air through the heat dissipation port 203, which can carry the heat dissipated by the battery energy storage unit 30 and the photovoltaic unit 10 to the outside space, reducing the number of heat dissipation systems required, saving heat dissipation costs, making the structure more compact, and reducing the space occupied. For example, there can be multiple heat dissipation ports 203, and at least some of the multiple heat dissipation ports 203 are arranged opposite each other.

[0080] like Figure 1 As shown, in some embodiments of this application, optionally, the heat dissipation port 203 includes a first sub-heat dissipation port 2031 and a second sub-heat dissipation port 2032, and the first sub-heat dissipation port 2031 and the second sub-heat dissipation port 2032 are arranged opposite to each other.

[0081] In the above embodiment, the heat dissipation port 203 includes a first sub-heat dissipation port 2031 and a second sub-heat dissipation port 2032 arranged opposite to each other, which can form air convection between the first sub-heat dissipation port 2031 and the second sub-heat dissipation port 2032, which is beneficial to improving the heat dissipation effect.

[0082] For example, there are multiple first sub-heat dissipation ports 2031 and second sub-heat dissipation ports 2032, and each first sub-heat dissipation port 2031 is provided with a corresponding second sub-heat dissipation port 2032.

[0083] like Figure 1 and Figure 2As shown, in some embodiments of this application, optionally, the support portion 20 includes: a first support member 21, a second support member 22, and a side support member 23; the first support member 21, the second support member 22, and the side support member 23 surround a mounting cavity 201. The photovoltaic portion 10 is disposed on the side of the first support member 21 opposite to the mounting cavity 201; the first support member 21 and the second support member 22 are located on opposite sides of the mounting cavity 201, and the battery energy storage portion 30 is disposed on the side of the second support member 22 close to the mounting cavity 201; the side support member 23 is disposed between the first support member 21 and the second support member 22, and the first support member 21, the second support member 22, and the side support member 23 surround a mounting cavity 201; wherein, the first sub-heat dissipation port 2031 and the second sub-heat dissipation port 2032 are both disposed on the side support member 23, and the position height of the first sub-heat dissipation port 2031 is lower than the position height of the second sub-heat dissipation port 2032.

[0084] In the above embodiment, the support portion 20 includes a first support member 21, a second support member 22, and a side support member 23. The first support member 21 supports the photovoltaic unit 10, the second support member 22 supports the battery energy storage unit 30, and the side support member 23 is disposed between the first support member 21 and the second support member 22, allowing the second support member 22 to further provide load-bearing capacity to the first support member 21. The mounting cavity 201 is formed by the first support member 21, the second support member 22, and the side support member 23, thereby enabling the first support member 21, the second support member 22, and the side support member 23 to jointly form a box structure, improving the overall load-bearing capacity of the support portion 20, and also providing better protection for the battery energy storage unit 30.

[0085] Because hot air in the mounting cavity 201 will rise due to its lower density when the temperature is high, by setting the position of the first sub-heat dissipation port 2031 to be lower than the position of the second sub-heat dissipation port 2032, hot air is discharged from the second sub-heat dissipation port 2032, while cold air from the outside enters from the first heat dissipation port 203, which can further increase the speed of air convection and thus further improve the heat dissipation effect.

[0086] For example, the second support member 12 can be used to connect to the side wall of the house 900 or to the top plate of the house 900.

[0087] like Figure 3 As shown, in some embodiments of this application, optionally, the first carrier 21 includes a skeleton 212 and a filler 214. The skeleton 212 is provided with a plurality of filling cavities 2101; the filler 214 is disposed in the filling cavity 2101; wherein, the filler 214 is made of a phase change material.

[0088] In the above embodiment, the first support member 21 includes a frame 212 and a filler 214. By filling the multiple filling cavities 2101 of the frame 212 with the filler 214 made of phase change material, the first support member 21 can have a certain temperature regulation capability. When the photovoltaic part 10 and the battery energy storage part 30 heat up, the filler 214 can absorb heat and become liquid, which plays a role in cooling and heat dissipation. At night or when the temperature drops, the filler 214 can release heat and become solid, ensuring the comfort inside the house 900.

[0089] For example, the outer surface of the frame 212 is coated with a building waterproofing material.

[0090] For example, the skeleton 212 can be a metal skeleton 212, such as an aluminum heat-conducting skeleton 212, or a concrete structure skeleton 212. The filling cavity 2101 of the skeleton 212 can be set in a honeycomb structure, which has both high structural strength and improved heat conduction efficiency.

[0091] For example, the filler 214 may be a phase change material such as paraffin or hydrated salt, with a selectable phase change temperature between 28°C and 35°C.

[0092] like Figure 2 As shown, in some embodiments of this application, optionally, the first support member 21 further includes at least one heat-conducting member 216, which is connected to the frame 212 and abuts against the battery energy storage unit 30.

[0093] In the above embodiment, the first support member 21 further includes at least one heat-conducting member 216; the heat generated by the battery energy storage unit 30 can be transferred to the heat-conducting member 216 through the contact between the heat-conducting member 216 and the battery energy storage unit 30. Part of the heat can be carried away by the flowing air in the mounting cavity 201, and another part can be transferred to the frame 212 through the heat-conducting member 216, and then dissipated through the frame 212.

[0094] For example, multiple heat-conducting elements 216 may be provided; the multiple heat-conducting elements 216 are evenly spaced within the mounting cavity 201.

[0095] like Figure 2 As shown, in some embodiments of this application, optionally, the support portion 20 further includes a support column 24, one end of which is connected to the first support member 21, and the other end of which is connected to the second support member 22.

[0096] In the above embodiment, a support column 24 is also provided between the first support member 21 and the second support member 22. The support column 24 is used to improve the structural strength between the first support member 21 and the second support member 22.

[0097] like Figure 2As shown, in some embodiments of this application, optionally, the support portion 20 further includes a heat insulation layer 25, which is disposed on the second support member 22 and located between the second support member 22 and the battery energy storage portion 30.

[0098] In the above embodiment, the support portion 20 further includes a heat insulation layer 25. The heat insulation layer 25 has good heat insulation performance and can effectively block the external ambient temperature from being transmitted into the mounting cavity 201 through the second support member 22, reduce the impact of external temperature changes on the operating temperature of the battery energy storage unit 30, maintain the stability of the temperature inside the mounting cavity 201, and provide a suitable operating temperature environment for the battery energy storage unit.

[0099] like Figure 2 As shown, in some embodiments of this application, optionally, the carrier 20 further includes a sealing member 26, and both the first carrier 21 and the second carrier 22 are provided with cable holes 204, and the sealing member 26 is disposed in the cable holes 204.

[0100] In the above embodiment, both the first support member 21 and the second support member 22 are provided with cable holes 204. The cable hole 204 located in the first support member 21 is used to pass through the cable connecting the photovoltaic unit 10 and the battery energy storage unit 30, and the cable hole 204 located in the second support member 22 is used to pass through the cable connecting the battery energy storage unit 30 to the distribution box or electrical equipment inside the house 900. By sealing the cable hole 204 with the sealing member 26, rainwater can be prevented from entering the mounting cavity 201 or the house through the cable hole 204, which helps to protect the battery energy storage unit 30 and electrical components such as cables.

[0101] For example, the mounting cavity 201 is provided with a cable channel for separating high and low voltage power. The cable channel is connected to the cable hole 204. The high voltage cable is wrapped with a metal shielding layer, such as a charging and discharging cable. The low voltage cable is physically isolated from it to reduce battery interference, such as a signal cable.

[0102] like Figure 1 and Figure 2 As shown, in some embodiments of this application, optionally, the battery energy storage unit 30 includes a plurality of supports 31 and a battery module 32. The plurality of supports 31 are disposed on the second support member 22 and are arranged at intervals; the battery module 32 is disposed on the supports 31 and is arranged at intervals from the second support member 22.

[0103] In the above embodiment, the battery energy storage unit 30 includes multiple brackets 31 and a battery module 32. The battery module 32 is mounted on the second support member 22 via the brackets 31. The multiple brackets 31 are arranged at intervals, which facilitates airflow between the multiple brackets 31 and improves the heat dissipation effect in the mounting cavity 201. The battery module 32 is arranged at intervals with the second support member 22, which on the one hand increases the contact area between the battery module 32 and the air and improves the heat dissipation capacity, and on the other hand, avoids water stains in the mounting cavity 201 from affecting the battery module 32.

[0104] For example, the battery module 32 includes battery cells and a BMS (Battery Management System).

[0105] For example, the number of battery modules 32 can be multiple.

[0107] In the above embodiment, the support portion 20 is provided with an inspection port 205 communicating with the mounting cavity 201. The inspection port 205 can be used for maintenance and repair of the battery module 32, and can also be used for installation and removal of the battery module 32. By providing a slide rail 33 on the bracket 31 and a slider 34 on the battery module 32, with the slider 34 slidably mounted on the slide rail 33 and one end of the slide rail 33 located at the inspection port 205, the battery module 32 can be slidably installed. When the battery module 32 needs maintenance or replacement, the operator does not need to go deep into the mounting cavity 201 for complex disassembly operations. They only need to pull the battery module 32 through the inspection port 205, and the battery module 32 can slide along the slide rail 33 via the slider 34 and be quickly pulled out from the inspection port 205. This reduces the difficulty of maintenance, reduces the time of maintenance operations, and significantly improves maintenance efficiency.

[0108] For example, the access port 205 may be provided on the side support 23 to facilitate workers to operate on the battery module 32.

[0109] like Figure 4As shown, in some embodiments of this application, the battery energy storage unit 30 may optionally include a quick connector 35, and the number of battery modules 32 is multiple, the multiple battery modules 32 are arranged in an array, and adjacent battery modules 32 are connected by quick connectors 35.

[0110] In the above embodiments, the battery modules 32 are arranged in an array, which allows for a regular arrangement of the battery modules 32, facilitating cable routing and making installation and disassembly easier for workers. Furthermore, the quick-connect fittings 35 enable rapid connection between the battery modules 32, improving assembly efficiency.

[0111] For example, the battery module 32 may employ a blind-mating short-circuit-protected connector. Furthermore, the housing of the battery module 32 may be provided with guide pins.

[0112] For example, quick-connect fitting 35 may employ a quick-lock mechanism.

[0113] like Figure 1 and Figure 2 As shown, in some embodiments of this application, optionally, the photovoltaic unit 10 includes a plurality of photovoltaic elements 11, which are interconnected.

[0114] In the above embodiment, the photovoltaic unit 10 is composed of a plurality of interconnected photovoltaic elements 11.

[0115] For example, the photovoltaic component 11 may be a photovoltaic tile or a flexible photovoltaic film.

[0116] like Figure 1 and Figure 2 As shown, in some embodiments of this application, optionally, the photovoltaic unit 10 further includes a plurality of support members 12, which are disposed between the photovoltaic unit 11 and the carrier unit 20, and the plurality of support members 12 are arranged at intervals.

[0117] In the above embodiments, the photovoltaic unit 10 also includes a plurality of support members 12, which are arranged at intervals between the photovoltaic unit 11 and the carrier unit 20. This can reduce the thermal impact of the photovoltaic unit 11 on the carrier unit 20, and also increase the heat dissipation area of ​​the photovoltaic unit 11 and improve the heat dissipation efficiency.

[0118] like Figure 1 As shown, in some embodiments of this application, optionally, the house energy storage module 901 further includes a protective mesh cover 40, which is disposed at the heat dissipation vent 203.

[0119] In the above embodiment, a protective mesh is provided on the heat dissipation vent 203 to prevent animals such as birds and rodents from entering, and to avoid the accumulation of dust and debris.

[0120] For example, the protective mesh cover 40 may be of the louver type.

[0121] like Figure 6 As shown, in some embodiments of this application, optionally, the house energy storage module 901 is prefabricated as part of the roof or side wall of the house, and the photovoltaic part 10 is exposed on the house surface.

[0122] In the above embodiments, the house energy storage module 901 is a prefabricated independent product. The house energy storage module 901 can be part of the roof of the house or part of the side wall. By exposing the photovoltaic unit 10 to the surface of the house, it is easier for the photovoltaic unit 10 to absorb solar energy and generate electricity.

[0123] For example, an integral structure consisting of multiple house energy storage modules 901 or a single house energy storage module 901 can be used directly as a roof or side wall.

[0124] For example, one or more home energy storage modules 901 may be installed on the roof or side wall as part of the roof or side wall.

[0125] like Figure 6 As shown, a second aspect of this application provides a house 900, including a side wall 902 and a roof 903 connected to the side wall, wherein at least one of the side wall 902 or the roof 903 includes one or more prefabricated house energy storage modules 901 as described in any of the above embodiments.

[0126] In the above embodiments, since the house 900 has the house energy storage module 901 in any of the above embodiments, it has all the beneficial effects of the house energy storage module 901 in any of the above embodiments, which will not be described in detail here.

[0127] In the above embodiments, the house 900 includes a roof 903 and a side wall 902. The roof 903 may contain a prefabricated house energy storage module 901, or the side wall 902 may contain a prefabricated house energy storage module 901; or both the roof 903 and the side wall 902 may contain prefabricated house energy storage modules 901.

[0128] Understandably, the house 900 consists of a roof 903 covering the top of the side wall 902.

[0129] For example, a prefabricated single housing energy storage module 901 is directly covered as a roof 903 on top of the side wall 902.

[0130] For example, multiple prefabricated housing energy storage modules 901 can be spliced ​​together to form an integral structure through connection structures such as slots and buckles, mortise and tenon structures, and the integral structure directly serves as the roof 903 covering the top of the side wall 902.

[0131] For example, one or more prefabricated house energy storage modules 901 are directly installed on the roof 903 or side wall 902 to perform photoelectric conversion as part of the roof 903 or side wall 902.

[0132] For example, the house energy storage module 901 is provided with a lifting eye hole, which can be used to install a lifting eye, and the house energy storage module 901 can be installed by hoisting.

[0133] For example, the home energy storage module 901 is provided with a handle structure, so that installers can move the home energy storage module 901 by hand for installation.
