[0035] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0036] As Figure 1 shown, an embodiment of the present application provides a high-voltage box 100. The high-voltage box 100 is generally in the shape of a cuboid and is used to control the charging and discharging of the battery. Among them, the length of the high-voltage box 100 is greater than twice the width of the high-voltage box 100, or the length of the high-voltage box 100 is greater than twice the height of the high-voltage box 100. That is to say, the high-voltage box 100 is in the shape of a flat plate or a long strip. The high-voltage box 100 can be installed in the energy storage cabinet by inserting, making the disassembly and assembly of the high-voltage box 100 simpler and also reducing the space occupied by the high-voltage box 100 in the energy storage cabinet. Further, if the length of the high-voltage box 100 is greater than twice the width of the high-voltage box 100 and twice the height of the high-voltage box 100, then the high-voltage box 100 is in the shape of a long strip. Optionally, the length, width and height of the high-voltage box 100 are 780 mm, 290 mm and 260 mm respectively.

[0037] As Figure 1 and Figure 2As shown in the figure, the high-voltage box 100 includes a first housing 1, a second housing 2, and a mounting plate 3. The second housing 2 is disposed in the first housing 1. The second housing 2 and the first housing 1 enclose a receiving space for receiving electrical components to protect the electrical components. The mounting plate 3 is disposed in the receiving space and is used for mounting electrical components, so that the electrical components can be mounted on the first housing 1 and the mounting plate 3. Further, the first housing 1 and the second housing 2 are hermetically connected. For example, a sealing ring or sealant is provided between the first housing 1 and the second housing 2 to increase the waterproofness of the receiving space and improve the problem that the high-voltage box 100 is damaged by water ingress caused by rain or liquid splashing. Optionally, the waterproof rating of the high-voltage box 100 is IP54, that is, the dustproof level is 5 and the waterproof level is 4. It cannot completely prevent dust from entering, but the amount of dust entering will not affect the normal operation of the product, and it can prevent water splashing from all directions from entering.

[0038] For the above-mentioned first housing 1, as Figure 2 shown, the first housing 1 includes a bottom plate 11, a front panel 12, and a rear plate 13. The bottom plate 11, the front panel 12, and the rear plate 13 can be rectangular. The front panel 12 and the rear plate 13 are respectively connected to both ends of the bottom plate 11. One end of each of the front panel 12 and the rear plate 13 is connected to the bottom plate 11, and both the front panel 12 and the rear plate 13 are perpendicular to the bottom plate 11. Therefore, the bottom plate 11, the front panel 12, and the rear plate 13 are connected to form a semi-enclosed frame shape. The second housing 2 and the bottom plate 11, the front panel 12, and the rear plate 13 enclose a receiving space. When the second housing 2 is disassembled from the first housing 1, the top plate 21 and both sides of the first housing 1 are exposed outward, facilitating the disassembly, assembly, and maintenance of the electrical components in the receiving space. Optionally, the first housing 1 is made of a metal material, such as steel or iron, which is beneficial to improving the strength and heat dissipation performance of the first housing 1. The first housing 1 can be integrally formed, for example, by bending a metal sheet. Optionally, the surface of the first housing 1 is sprayed with insulating paint, such as paint, which can not only improve the insulation of the first housing 1 but also enhance the corrosion resistance.

[0039] As Figure 2 and Figure 3As shown, the first housing 1 further includes a support plate 14. The support plate 14 can be rectangular. One end of the support plate 14 is connected to the bottom plate 11; one end of the mounting plate 3 is connected to the front panel 12, and the other end of the mounting plate 3 is connected to the other end of the support plate 14. That is to say, the mounting plate 3 is spaced from the bottom plate 11. Both the mounting plate 3 and the bottom plate 11 can be used to mount electrical components, so that the electrical components in the high-voltage box 100 can be arranged in a double layer, and the layout of the electrical components can be more compact, which is beneficial to improving the utilization rate of the accommodation space and reducing the volume of the high-voltage box 100. Optionally, the support plate 14 and the mounting plate 3 are made of metal materials, such as steel or iron, which is beneficial to improving the strength and heat dissipation performance of the support plate 14 and the mounting plate 3. Optionally, the surfaces of the support plate 14 and the mounting plate 3 are sprayed with insulating paint, such as paint, which can not only improve the insulation of the support plate 14 and the mounting plate 3, but also enhance the corrosion resistance. Optionally, the support plate 14 is detachably connected to the bottom plate 11 by screws, and the mounting plate 3 is detachably connected to the support plate 14 and the front panel 12 by screws.

[0040] In some embodiments, as Figure 2 and Figure 3 shown, the mounting plate 3 is provided with heat dissipation fins 31 to improve the heat dissipation performance of the mounting plate 3.

[0041] For the above-mentioned bottom plate 11, as Figure 2 and Figure 3 shown, the bottom plate 11 includes a first mounting area 111 located between the support plate 14 and the front panel 12, and the bottom plate 11 includes a second mounting area 112 located between the support plate 14 and the rear plate 13. Both the first mounting area 111 and the second mounting area 112 are used to mount electrical components. The support plate 14 can separate the electrical components in the first mounting area 111 from the electrical components in the second mounting area 112, reducing the mutual influence between the electrical components in the first mounting area 111 and the electrical components in the second mounting area 112.

[0042] For the above-mentioned front panel 12, as Figure 3As shown in the figure, the front panel 12 is provided with a signal terminal 121, a power terminal 122, a grounding terminal 123, a switch assembly 124, and an alarm 125. The signal terminal 121 is used to connect an external signal cable, the power terminal 122 is used to connect an external power cable, the grounding terminal 123 is used to connect a grounding cable, the switch assembly 124 is used to control the high-voltage box 100, and the alarm 125 is used to emit an audible and visual alarm. The signal terminal 121, the power terminal 122, the grounding terminal 123, the switch assembly 124, and the alarm 125 are all arranged on the front panel 12. When the high-voltage box 100 is inserted into the energy storage cabinet, the signal terminal 121, the power terminal 122, the grounding terminal 123, the switch assembly 124, and the alarm 125 can all be exposed outside the energy storage cabinet, facilitating the connection of cables to the high-voltage box 100 and the operation of the high-voltage box 100. In some other embodiments, one or more of the signal terminal 121, the power terminal 122, the grounding terminal 123, the switch assembly 124, and the alarm 125 are arranged on the front panel 12. Among them, the power terminal 122 includes two groups, one group is connected to the electrical equipment, and the other group is connected to the battery. Optionally, the grounding terminal 123 is connected to the mounting plate 3.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown in the figure, one end of the mounting plate 3 is connected to the middle of the front panel 12, and the signal terminal 121 and the power terminal 122 are respectively located on both sides of the mounting plate 3, so that the signal terminal 121 and the power terminal 122 are distributed in zones on the front panel 12, facilitating the connection of external signal cables and external power cables, and reducing the mutual interference between the signal terminal 121 and the power terminal 122.

[0044] In some embodiments, such as Figure 3 As shown in the figure, the front panel 12 is detachably provided with a cover plate 126. It can be understood that after the cover plate 126 is removed, there is an opening (not shown) on the front panel 12 that communicates with the accommodating space. By removing the cover plate 126, it is convenient to maintain and repair the electrical components near the front panel 12 inside the high-voltage box 100 without removing the second housing 2, facilitating the maintenance and repair of the high-voltage box 100 by the staff and improving the efficiency of maintenance and repair. Optionally, the cover plate 126 is detachably connected to the front panel 12 by screws.

[0045] For the above-mentioned second housing 2, such as Figure 1 and Figure 2As shown, the second housing 2 includes a top plate 21 and two side plates 22. The top plate 21 and the two side plates 22, together with the first housing 1, enclose a receiving space. It can be understood that the bottom plate 11, the front panel 12, and the rear panel 13 are connected to form a semi-enclosed frame shape, and the top plate 21 and the two side plates 22, together with the first housing 1, enclose a receiving space. Therefore, the top plate 21 and the two side plates 22 are also connected to form a semi-enclosed frame shape. Exemplarily, both ends of the top plate 21 are respectively connected to the two side plates 22. One end of each of the two side plates 22 is connected to the top plate 21, and the two side plates 22 are both perpendicular to the top plate 21. Therefore, the top plate 21 and the two side plates 22 are connected to form a semi-enclosed frame shape. Further, at least one of the side plates 22 is detachably connected to the top plate 21. When disassembling the second housing 2, only the top plate 21 or the side plate 22 can be disassembled, without completely disassembling the second housing 2, which is convenient for the staff to maintain and repair the high-voltage box 100 and improves the efficiency of maintenance and repair. Optionally, the second housing 2 is made of a metal material, such as steel or iron, which is beneficial to improving the strength and heat dissipation performance of the second housing 2. The second housing 2 can be integrally formed, for example, by bending a metal sheet. Optionally, the surface of the second housing 2 is sprayed with an insulating paint, such as paint, which can not only improve the insulation of the second housing 2 but also enhance the corrosion resistance. Optionally, the top plate 21 and the side plates 22 are detachably connected to the first housing 1 by screws.

[0046] As Figure 2 shown, an insulating sheet 221 is provided on the side of the side plate 22 facing the receiving space. The insulating sheet 221 can be a plastic sheet or a plastic film to enhance the insulation performance of the side plate 22.

[0047] As Figure 2 shown, the second housing 2 is provided with ventilation holes 222. The ventilation openings can be specifically provided on the side plates 22, which is beneficial to the air circulation inside and outside the high-voltage box 100 and enhances the heat dissipation effect of the high-voltage box 100. Further, ventilation holes 222 are provided on both side plates 22, and the ventilation holes 222 on the two side plates 22 are staggered. That is to say, when observing in the direction perpendicular to the side plates 22, the ventilation holes 222 on the two side plates 22 are spaced apart, thereby extending the path length of the air flowing inside the high-voltage box 100 and enhancing the heat dissipation effect. Optionally, the second housing 2 is provided with louver air vents 223, and the louver air vents 223 have ventilation holes 222.

[0048] In some embodiments, as Figure 2 and Figure 3As shown, the high-voltage box 100 further includes a signal component 4 and a connection component 5. The signal component 4 is connected to the signal terminal 121. The signal component 4 is used to connect to other electrical components inside the high-voltage box 100. For example, both the signal component 4 and other electrical components are provided with terminals, and are connected through cables to the terminals to connect the signal component 4 to other electrical components inside the high-voltage box 100. The connection component 5 includes a connection piece 51, a fuse 52, and a current sensor 53. The connection piece 51 is connected to two groups of power terminals 122 to connect the two groups of power terminals 122; the fuse 52 is connected in series between the two groups of power terminals 122. The fuse 52 is used to melt itself when the current on the connection piece 51 is too large to disconnect the connection between the two groups of power terminals 122; the current sensor 53 is connected in series between the two groups of power terminals 122. The current sensor 53 is used to detect the current on the connection piece 51. Optionally, the model of the terminal of the signal component 4 is DS2.5-QU-01P-1Y-00A(H). Optionally, the connection piece 51 is a copper bar, the model of the fuse 52 is PV312-XL1-T, and the model of the current sensor 53 is STB-CAB500.

[0049] Among them, the signal component 4 is arranged on the side of the mounting plate 3 away from the bottom plate 11, and the connection component 5 is arranged in the first mounting area 111; the signal terminal 121 and the signal component 4 are on the same side of the mounting plate 3, and the connection component 5 and the power terminal 122 are on the other side of the mounting plate 3. Through the above arrangement, the distance between the signal component 4 and the signal terminal 121 is shortened, the distance between the connection component 5 and the power terminal 122 is shortened, and the signal component 4 and the connection component 5 are respectively on opposite sides of the mounting plate 3, making the arrangement of the mounting plate 3, the front panel 12, the connection component 5 and the signal component 4 more compact, which is beneficial to reducing the volume of the high-voltage box 100. Moreover, each electrical component of the connection component 5, such as the connection piece 51, the fuse 52, and the current sensor 53, is concentrated in the first mounting area 111, so that each electrical component of the connection component 5 can be arranged more compactly, which is beneficial to reducing the volume of the high-voltage box 100.

[0050] As Figure 2 and Figure 3 shown, the connection component 5 further includes a disconnect switch 54. The disconnect switch 54 is connected in series between the two groups of power terminals 122. The disconnect switch 54 is exposed from the opening of the front panel 12. After the cover plate 126 is removed, the disconnect switch 54 can be operated.

[0051] In some embodiments, as Figure 2 shown, the insulating sheet 221 of the side plate 22 faces the connection component 5, that is, when observing along the direction perpendicular to the side plate 22, the insulating sheet 221 coincides with the connection component 5, thereby enhancing the insulation performance between the connection component 5 and the side plate 22.

[0052] In some embodiments, as Figure 2 and Figure 3 shown, the high-voltage box 100 further includes a power supply assembly 6, and the power supply assembly 6 is disposed on at least one of the second installation area 112, the rear plate 13, and the support plate 14. The power supply assembly 6 and the electrical connection assembly 5 are located on both sides of the support plate 14, which is beneficial to reducing the mutual influence between the power supply assembly 6 and the electrical connection assembly 5. Since the electrical components of the power supply assembly 6 are similar electrical components, the mutual influence between the electrical components of the power supply assembly 6 is small. In this embodiment, the power supply assembly 6 is centrally disposed on the second installation area 112, the rear plate 13, and the support plate 14, so that the electrical components of the power supply assembly 6 can be arranged more compactly, which is beneficial to reducing the volume of the high-voltage box 100. The power supply assembly 6 is arranged two-dimensionally on the second installation area 112, the rear plate 13, and the support plate 14, making the arrangement of the power supply assembly 6 more compact.

[0053] In some embodiments, as Figure 2 and Figure 3 shown, the power supply assembly 6 includes a battery management module 61, an industrial control power supply 62, an inverter power supply 63, and a redundant system control module 64. The battery management module 61 is disposed on the support plate 14, the industrial control power supply 62 is disposed on the second installation area 112, and both the inverter power supply 63 and the redundant system control module 64 are disposed on the rear plate 13. The redundant system control module 64 is connected to the battery management module 61, the industrial control power supply 62, and the inverter power supply 63, and is used to improve the reliability of the power supply assembly 6. Optionally, the model of the industrial control power supply 62 is MPT210-350, the model of the inverter power supply 63 is PV350-29B32W, and the model of the redundant system control module 64 is DR-RDN20.

[0054] The high-voltage box 100 according to the embodiment of the present application has the mounting plate 3 spaced from the bottom plate 11. Both the mounting plate 3 and the bottom plate 11 can mount electrical components, enabling the electrical components in the high-voltage box 100 to be arranged in a double layer, and the layout of the electrical components can be more compact, which is conducive to improving the utilization rate of the accommodation space and reducing the volume of the high-voltage box 100. The high-voltage box 100 has a first mounting area 111, a second mounting area 112, and the mounting area on the mounting plate 3, enabling the signal assembly 4, the connection assembly 5, and the power supply assembly 6 to be partitioned and arranged, which is conducive to increasing the compactness of the arrangement of the electrical components in the signal assembly 4, the connection assembly 5, and the power supply assembly 6. When the second housing 2 is detached from the first housing 1, the top plate 21 and both sides of the first housing 1 are exposed outward, facilitating the disassembly, assembly, and maintenance of the electrical components in the accommodation space. The front panel 12 is detachably provided with a cover plate 126, facilitating the staff to maintain and repair the electrical components near the front panel 12 inside the high-voltage box 100. When detaching the second housing 2, only the top plate 21 or the side plate 22 can be detached, facilitating the staff to maintain and repair the high-voltage box 100 and improving the efficiency of maintenance and repair.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above.
