[0104] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0105] With the continuous development of battery energy storage technology, the energy density of energy storage devices is getting higher and higher.

[0106] In related technologies, energy storage devices have a battery compartment and a control compartment. The battery compartment houses the battery device, and the control compartment houses the power distribution device. The battery device and the power distribution device are electrically connected.

[0107] However, the power distribution equipment occupies the space of the energy storage device, making it difficult to improve the integration of the energy storage device, which in turn makes it difficult to improve the energy density of the energy storage device.

[0108] Firstly, combining Figures 1-4 This application provides a distribution box 10, which is applied to an energy storage device 20. The distribution box 10 includes a box body 100 and at least two electrical components.

[0109] The enclosure 100 has a receiving cavity 110. The receiving cavity 110 includes at least two mounting areas. At least two electrical components are placed in different mounting areas.

[0110] Thus, by installing different electrical components in at least two mounting areas within the accommodating cavity 110, a modular installation design is achieved, making maintenance and replacement of each component more convenient and improving the integration of the distribution box 10. With each electrical component concentrated in its corresponding mounting area, the connections between components are compact, reducing the space occupied by the distribution box 10. Electrical isolation is also provided between components in different mounting areas, reducing mutual interference and improving the operational stability of the distribution box 10. Furthermore, when the distribution box 10 and the energy storage device 20 are used together, the internal space occupied by the distribution box 10 within the energy storage device 20 can be reduced, thereby increasing the number of battery devices within the energy storage device 20 and thus increasing its energy density.

[0111] It should be noted that the installation area in this embodiment can be two or more, and this embodiment does not require it to be one.

[0112] In some embodiments, the installation area includes a first installation area 210, and the housing 100 includes a first surface 111, with the first installation area 210 located adjacent to the first surface 111. The electrical component includes a first electrical component, which is disposed within the first installation area 210. In this embodiment, the first installation area 210 is positioned close to the first surface 111, making the first electrical component within the first installation area 210 more convenient to install and remove. Furthermore, placing the first electrical component requiring user operation within the first installation area 210 improves user accessibility and ease of operation.

[0113] For example, the box 100 in this application embodiment can be a cube or a cuboid, and the first surface 111 can be any surface of the box 100. This application embodiment does not make specific requirements in this regard.

[0114] In one specific embodiment, the first surface 111 may be the front wall surface of the housing 100.

[0115] For example, the first electrical component includes an input terminal 301 and an output terminal 302, wherein the input terminal 301 is used to input signals and the output terminal 302 is used to input signals.

[0116] In some embodiments, there may be multiple input terminals 301 and multiple output terminals 302. The specific number of input terminals 301 and output terminals 302 is not specifically required in this application embodiment.

[0117] In this embodiment, the input terminal 301 and the output terminal 302 are disposed in the first mounting area 210, and the input terminal 301 and the output terminal 302 are close to the first surface 111, which facilitates wiring and operation by the user.

[0118] In some embodiments, the first surface 111 has an opening 1111, through which at least one of the input terminal 301 and the output terminal 302 passes and extends to the outside of the first surface 111. This allows the user to directly connect the input terminal 301 and the output terminal 302, making the distribution box 10 easier to use. Furthermore, it reduces the space occupied by the input terminal 301 and the output terminal 302 in the first mounting area 210, thereby reducing the space ratio of the distribution box 10 and contributing to increasing the energy density of the energy storage device 20.

[0119] In some embodiments, the mounting area further includes a second mounting area 220, and the first mounting area 210 and the second mounting area are located on different sides of the housing 100 along the first direction.

[0120] It can be understood that when the first direction is the width direction of the distribution box 10, the second direction is the length direction of the distribution box 10. When the first direction is the length direction of the distribution box 10, the second direction is the width direction of the distribution box 10. This application embodiment uses the example of the first direction being the length direction of the distribution box 10 and the second direction being the width direction of the distribution box 10 for explanation.

[0121] Here, the first direction is defined as the Y direction, the first direction is defined as the X direction, and the height direction of the distribution box 10 is defined as the Z direction.

[0122] It is easy to understand that the first mounting area 210 can be located on the side closer to the second surface 112, and correspondingly, the second mounting area 220 can be located on the side closer to the third surface 113. Alternatively, the first mounting area 210 can be located on the side closer to the third surface 113, and the second mounting area 220 can be located on the side closer to the second surface 112. This application embodiment does not limit the specific positions of the first mounting area 210 and the second mounting area 220 along the first direction.

[0123] In some embodiments, the first mounting area 210 and the second mounting area 220 are arranged adjacent to each other along the first direction. Thus, by arranging the first mounting area 210 and the second mounting area 220 adjacently, the relative positions between the first electrical component and the second electrical component are more compact, which can reduce the length of the connecting wires for electrical connections between the components and lower material costs.

[0124] Along the first direction, the projection of the first mounting area 210 onto the housing 100 does not coincide with the projection of the second mounting area 220 onto the housing 100.

[0125] In some embodiments, the electrical component includes a second electrical component disposed within the second mounting area 220.

[0126] In some embodiments, the second electrical component includes a first terminal block 305, which passes through the opening 1111 and extends to the outside of the first surface 111. The distribution box 10 is connected to and electrically conductive with an external power source through the first terminal block 305, enabling it to supply power to the third electrical component. The first terminal block 305 can be installed in the second mounting area 220. In this embodiment, the extension of the first terminal block 305 to the first surface 111 facilitates the connection between the first terminal block 305 and the external power source, thus facilitating the power distribution connection of the distribution box 10.

[0127] In some embodiments, the energy storage device 20 includes an air conditioner and a battery. The battery generates heat during charging and discharging. Because the energy storage device 20 has a high energy density, the heat generated by the battery needs to be dissipated through the air conditioner to maintain the battery temperature at a stable operating temperature. The air conditioner is powered by the distribution box 10.

[0128] For example, the second electrical component further includes a second terminal block 307, which is electrically connected to the first terminal block 305. The second terminal block 307 is used for electrical connection with the air conditioner of the energy storage device 20. The second terminal block 307 passes through the opening 1111 and extends to the outside of the first surface 111. A current path is formed through the electrical connection between the first terminal block 305, the second terminal block 307, and the air conditioner of the energy storage device 20 to supply power to the air conditioner of the energy storage device 20. In this embodiment, the second terminal block 307 extends to the outside of the first surface 111 to facilitate the connection of the electrical connection wire between the second terminal block 307 and the air conditioner of the energy storage device 20.

[0129] In some embodiments, the second electrical component includes a first microswitch 306, which is electrically connected to a first terminal 305 and a second terminal 307, respectively; the first microswitch 306 passes through the opening 1111 and extends to the outside of the first surface 111.

[0130] See Figure 3 A first microswitch 306 is connected in series with a first terminal 305 and a second terminal 307. The first microswitch 306 is also connected in series with the first terminal 305 and a third electrical component. Thus, the circuit's conduction state is controlled by opening and closing the switch contacts of the first microswitch 306. The first microswitch 306 can be disposed in the second mounting area 220, passing through the opening 1111 and extending to the outside of the first surface 111, allowing the user to operate the first microswitch 306.

[0131] In some embodiments, the second electrical component further includes a third terminal block 308 and a second microswitch 309, the third terminal block 308 being electrically connected to the third electrical component; the second microswitch 309 being disposed between the third terminal block 308 and the third electrical component; the second microswitch 309 passing through the opening 1111 and extending to the outside of the first surface 111.

[0132] See Figure 3 The third terminal 308 is connected to and electrically conductive with an external power source. The third terminal 308 can be set in the second mounting area 220 to facilitate wiring connection between the second micro-control switch 309 in the second mounting area 220, which can save on wiring materials and reduce the cost of the distribution box 10.

[0133] In addition, in this embodiment, the second micro-control switch 309 is disposed in the second mounting area 220 so as to connect and conduct electricity with the third terminal 308. The second micro-control switch 309 is connected in series between the third terminal 308 and the third electrical component to form a current branch, and the on / off state of the current branch is controlled by the second micro-control switch 309.

[0134] It should be noted that the external power supply connected to the third terminal 308 in this embodiment is 220V AC mains power.

[0135] Thus, two current input paths are formed through the first terminal 305, the first micro-switch 306, the third terminal 308, and the second micro-switch 309, and the current flow path is selected through the first micro-switch 306 and the second micro-switch 309 on each path.

[0136] It should be noted that when the first terminal 305 in this embodiment is connected to an external power source, the external power source can be three-phase.

[0137] In some embodiments, the second electrical component also includes a surge arrester 315, which may be installed in the second mounting area 220. The surge arrester 315 and the first micro-switch 306 are electrically connected and can be grounded to ensure the safety of the distribution box 10.

[0138] In some embodiments, the second electrical component further includes a residual current device (RCD) 311 and a socket 312. The RCD 311 is connected in series with the first microswitch 306, and the socket 312 is connected in series with the RCD 311 and grounded, thus forming a current branch. The RCD 311 protects the circuit and the user's personal safety. Additionally, in this embodiment, the RCD 311 and socket 312 can be located in the second mounting area 220 for easy connection to the first terminal block 305.

[0139] The second electrical component also includes a relay 313, which is connected in series with the first micro-switch 306 and the third electrical component to control the on / off state of the circuit.

[0140] In some embodiments, the second electrical component further includes a splitter 310, which is electrically connected to the first microswitch 306, the residual current device 311, the relay 313, and the surge arrester 315.

[0141] In some embodiments, the second electrical component also includes an instrument 314, which is electrically connected to the first terminal 305 to measure the connecting wires led out from the first terminal 305 through the inductive power taking device of the instrument 314, so as to obtain the voltage value, current value, etc. in the circuit through the instrument 314, which is convenient for the user to observe and judge.

[0142] In some embodiments, the instrument 314 passes through the opening 1111 and extends to the outside of the first surface 111. Thus, the instrument 314 is exposed from the opening 1111 of the first surface 111 for user observation. Furthermore, the instrument 314 is positioned in the second mounting area 220 for easy installation and maintenance.

[0143] It should be noted that the second electrical component is prone to damage during use. Placing the second electrical component in the second installation area 220 facilitates its installation, replacement, and maintenance, reduces the maintenance difficulty of the distribution box 10, and improves maintenance efficiency.

[0144] Optional, combined Figure 1 , Figure 2 , Figure 3 , Figure 4 The partition 200 is disposed within the receiving cavity 110 and divides the receiving cavity 110 into at least two installation areas.

[0145] For example, the separator 200 includes a first separator 240, the first separator 240 and the first surface 111 are disposed opposite each other along a second direction, and the first mounting area 210 is located between the first separator 240 and the first surface 111; the second direction intersects the height direction of the distribution box 10.

[0146] It should be noted that the second direction can be either the length or width of the distribution box 10. This embodiment uses the width of the distribution box 10 as an example for illustration.

[0147] Optionally, the first separator 240 includes a first extension 241, which extends along a first direction. The first extension 241 and the first surface 111 are opposite to and spaced apart along a second direction, forming a first mounting area 210. Thus, the first extension 241, positioned within the receiving cavity 110 of the housing 100, forms the first mounting area 210 and provides mounting support for the components of the first electrical assembly within the first mounting area 210, ensuring stable connection of the first electrical assembly within the distribution box 10.

[0148] In this embodiment, the first partition 240 and the first surface 111 are opposite to each other along the second direction. The first partition 240 may be opposite to a portion of the first surface 111 or may be completely opposite to the first surface 111; this application does not specify a particular requirement in this regard. In this application embodiment, the first mounting area 210 may be formed on the surface of the first partition 240 facing the first surface 111, or in the space between the first partition 240 and the first surface 111.

[0149] It is easy to understand that by the relative arrangement of the first partition 240 and the first surface 111, the space of the accommodating cavity 110 can be effectively utilized to arrange more electrical components within a limited space, thereby increasing the functional density of the distribution box 10, improving the integration of the distribution box 10, and reducing the space ratio of the distribution box 10. In addition, the first partition 240 forms a structural support for the electrical components within the first mounting area 210, enabling the electrical components to be stably installed within the first mounting area 210.

[0150] In this embodiment of the application, in order to facilitate the understanding of the content of the embodiment of the application by those skilled in the art, combined with Figure 1 , Figure 3 The two opposing surfaces of the housing 100 along the second direction are defined as the second surface 112 and the third surface 113. Along the second direction, the first mounting area may be located on the side closer to the second surface 112, or the first mounting area may be located on the side closer to the third surface 113. This application embodiment does not impose specific requirements on this.

[0151] Optionally, the first separator 240 further includes a second extension 242, which extends along a first direction and is opposite to and spaced from the first surface 111 along the first direction to form a second mounting area 220. Thus, the second extension 242, positioned within the receiving cavity 110 of the housing 100, forms the second mounting area 220 and provides mounting support for the components of the second electrical assembly within the second mounting area 220, ensuring stable connection of the second electrical assembly within the distribution box 10.

[0152] It should be noted that, in this embodiment, the relative positions of the first extension segment 241 and the second extension segment 242 on the first separator 240 are the same as the positions of the corresponding first mounting area 210 and the corresponding second mounting area 220. That is, along the first direction, the first extension segment 241 may be close to the second surface 112 or the third surface 113 of the housing 100, and the second extension segment 242 may be close to the third surface 113 or the second surface 112 of the housing 100.

[0153] In some embodiments, the second extension 242 and the first extension 241 are misaligned along the second direction. That is, along the second direction, the distance between the second extension 242 and the first surface 111 is different from the distance between the first extension 241 and the first surface 111.

[0154] In this embodiment of the application, the distance between the second extension segment 242 and the first surface 111 may be greater than the distance between the first extension segment 241 and the first surface 111, or the distance between the second extension segment 242 and the first surface 111 may be less than the distance between the first extension segment 241 and the first surface 111. This part does not make specific requirements for this.

[0155] Thus, the first extension 241 and the second extension 242 form a first installation area 210 and a second installation area 220 with different spatial sizes, so that components of different sizes of electrical components can be adapted according to the spatial size of the first installation area 210 and the second installation area 220, so that the electrical components can be concentrated in different installation areas, which facilitates the installation and maintenance of the electrical components in the first installation area 210 and the second installation area 220.

[0156] In some embodiments, along the second direction, the maximum distance between the first extension 241 and the first surface 111 is less than the minimum distance between the second extension 242 and the first surface 111. That is, along the first direction, the first extension 241 is closer to the first surface 111, and the second extension 242 is farther away from the first surface 111. In this case, along the second direction, the first mounting area 210 can be used to install a first electrical component with a smaller space occupation, and the second mounting area 220 can be used to install a second electrical component with a relatively larger space occupation. Furthermore, by varying the distances between the first extension 241 and the second extension 242 and the first surface 111, the first mounting area 210 and the second mounting area 220 can have different installation functions.

[0157] In some embodiments, the extension length of the first extension segment 241 along the first direction is different from the extension length of the second extension segment 242. It can be understood that the extension length of the first extension segment 241 along the first direction can be less than the extension length of the second extension segment 242 along the first direction, or the extension length of the first extension segment 241 along the first direction can be greater than the extension length of the second extension segment 242 along the first direction. In this way, the second mounting area 220 has a larger installation space than the first mounting area 210, allowing the second mounting area 220 to install components of the second electrical assembly that occupy a larger proportion of the space. At the same time, the spacing between the components of the first electrical assembly within the first mounting area 210 is also relatively large, which not only facilitates the installation and maintenance of each component but also facilitates the wiring layout of the electrical connections between the components, preventing mutual interference between components that are close to each other in the electrical assembly, thus ensuring the overall stable and reliable operation of the distribution box 10.

[0158] See Figure 3 In some embodiments, along the first direction, the extension length of the first extension 241 is less than the extension length of the second extension 242.

[0159] In some implementations, combined Figures 1-4 The first separator 240 further includes a connecting extension 243, which connects the first extension 241 and the second extension 242; the connecting extension 243 extends along a second direction. In this embodiment, the connection extension 243 ensures a stable connection between the first extension 241 and the second extension 242 within the accommodating cavity 110, while preventing communication between the first mounting area 210 and other mounting areas within the accommodating cavity 110, thereby improving the stability of the circuits and signals within the distribution box 10.

[0160] In some implementations, see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 The mounting area also includes a third mounting area 230; along the second direction, the third mounting area 230 is located on the side of the first mounting area 210 away from the first surface 111.

[0161] To facilitate understanding of the embodiments of this application by those skilled in the art, the surface of the enclosure wall of the enclosure 100 opposite to the first surface 111 along the second direction is defined as the fourth surface 114, and the surfaces of the enclosure 100 opposite to the two enclosure walls along the height direction of the distribution box 10 are the fifth surface 115 and the sixth surface 116, respectively.

[0162] In the second direction, the third mounting area 230 is located on the side of the first partition away from the first surface 111, relative to the first mounting area 210. It can be understood that the third mounting area 230 on the side of the first partition away from the first surface 111 can be located close to at least one of the second surface 112, the third surface 113, the fourth surface 114, the fifth surface 115, and the sixth surface 116, or the third mounting area 230 can be located close to the surface of the first mounting area 210 on the side away from the first surface 111. This application embodiment does not make specific requirements in this regard. Thus, based on the first installation area 210 and the second installation area 220, the embodiment of this application divides the accommodating cavity 110 into different functional areas by setting the third installation area 230 to install electrical components with different functions. This helps to realize the modular design of the distribution box 10, thereby improving the integration of the distribution box 10 and making the electrical connection layout between the various components of the electrical components compact, thereby reducing the space ratio of the distribution box 10. Furthermore, when the distribution box 10 is installed in the energy storage device 20, the energy density of the energy storage device 20 is improved.

[0163] See Figure 3 , Figure 4As an optional implementation, the first partition 240 extends along the height direction of the distribution box 10, and the first mounting area 210 and the third mounting area 230 are located on opposite sides of the first partition 240 along the first direction. In this embodiment, the extension of the first partition 240 along the height direction of the distribution box 10 facilitates the assembly and connection of the first partition 240 and the box body 100, improving the production efficiency of the distribution box 10. Furthermore, the first partition 240 creates clear boundaries between the first mounting area 210, the second mounting area 220, and the third mounting area 230, allowing electrical components to be placed in the corresponding first mounting area 210 and third mounting area 230 according to their functions. This further reduces the mutual influence between electrical components in the second mounting area 220 and the third mounting area 230, such as electromagnetic interference, thereby enhancing the operational stability and reliability of the distribution box 10.

[0164] As an optional implementation method, combined with Figures 7-10 The third installation area 230 includes a first installation sub-area 231 and a second installation sub-area 232. Along the height direction of the distribution box 10, the second installation sub-area 232 is close to the top of the box 100, and the first installation sub-area 231 is close to the bottom of the box 100. The second installation sub-area 232 and the first installation sub-area 231 are arranged adjacent to each other.

[0165] In this embodiment, by arranging the second mounting sub-area 232 and the first mounting sub-area 231 along the height direction of the distribution box 10, natural convection can be used for thermal management of the electrical components within the third mounting area 230. Since heat typically rises, components that generate more heat can be placed in the first mounting sub-area 231 to utilize the rising airflow for heat dissipation. Furthermore, by rationally utilizing the space of the third mounting area 230 along the height direction of the distribution box 10, the space utilization rate of the third mounting area 230 is improved. And by rationally distributing the weight of the electrical components, the weight distribution of the electrical components within the third mounting area 230 is balanced, resulting in a uniform mass distribution of the distribution box 10, improving the stability of the distribution box 10, and reducing shaking during transportation.

[0166] See Figure 7 and Figure 8In some embodiments, the separator 200 further includes a second separator 250 extending along a second direction and intersecting with the first separator 240. Along the height direction of the distribution box 10, the second mounting sub-area 232 and the first mounting sub-area 231 are located on opposite sides of the second separator 250. Thus, the second separator 250 makes the second mounting sub-area 232 and the first mounting sub-area 231 independent of each other, and forms a clear boundary between them. This reduces the mutual influence between the components of the electrical assembly within the corresponding second mounting sub-area 232 and first mounting sub-area 231. In other words, when the electrical components in the distribution box 10 complete signal transmission, electromagnetic interference between the second mounting sub-area 232 and the first mounting sub-area 231 can be reduced, improving the stability and reliability of signal transmission in the distribution box 10.

[0167] In addition, in this embodiment, both the second partition 250 and the first partition 240 can serve as the mounting base for electrical components in the third mounting area 230, thereby stabilizing the connection of each component of the electrical components in the third mounting area 230 and improving the structural stability and safety of the distribution box 10.

[0168] In some embodiments, the distance between the second partition 250 and the top and bottom of the box 100 is different along the height direction of the distribution box 10.

[0169] It is understood that in this embodiment, the distance between the second partition 250 and the top of the housing 100 can be greater than the distance between the second partition 250 and the bottom of the housing 100, or the distance between the second partition 250 and the top of the housing 100 can be less than the distance between the second partition 250 and the bottom of the housing 100. This results in different spatial capacities for the second mounting sub-area 232 and the first mounting sub-area 231, better accommodating components of different sizes in the electrical assembly and improving the space utilization of the third mounting area 230. Furthermore, by adjusting the spatial size of the second mounting sub-area 232 and the first mounting sub-area 231, the electrical connection lines between electrical components can be made more direct, and the layout of the electrical connection lines can be simpler and more convenient, reducing the length of the electrical connection lines and lowering the material cost of the distribution box 10.

[0170] See Figure 7 and Figure 8 In one exemplary embodiment, along the height direction of the distribution box 10, the distance between the second partition 250 and the top of the box body 100 is greater than the distance between the second partition 250 and the bottom of the box body 100.

[0171] In some embodiments, the distribution box 10 further includes a heat dissipation assembly disposed in the box body 100, which is used to dissipate heat from the accommodating cavity 110 of the box body 100. The embodiments of this application, by providing a heat dissipation assembly, aim to stabilize the operating temperature of the electrical components within the distribution box 10, prevent temperature concentration inside the distribution box 10 and avoid localized overheating, thereby further ensuring the safety and operational stability of the distribution box 10.

[0172] Optionally, the heat dissipation component includes a fan 400, which is disposed within the housing 100; the air inlet or outlet side of the fan 400 faces the receiving cavity 110. Thus, when the air inlet side of the fan 400 faces the receiving cavity 110, the fan 400 can exhaust air from the receiving cavity 110; when the air outlet side of the fan 400 faces the receiving cavity 110, the fan 400 can introduce external air from the distribution box 10 into the receiving cavity 110. In this way, the placement of the fan 400 increases the airflow rate within the receiving cavity 110, further improving the heat dissipation efficiency of the electrical components within the receiving cavity 110.

[0173] In some embodiments, the enclosure 100 includes a support frame 117 and a plurality of panels 118, the panels 118 and the frame walls of the support frame 117 being detachably connected to form an accommodating cavity 110. Such an enclosure 100, through the detachable connection between the panels 118 and the support frame 117, facilitates the assembly and disassembly of the enclosure 100, as well as the installation and disassembly of electrical components.

[0174] It should be noted that the separator 200 in this embodiment can be detachably connected to the frame wall of the support frame 117.

[0175] The structure of the distribution box 10 will be described below in conjunction with the assembly of multiple electrical components in different installation areas.

[0176] In some embodiments, the enclosure 100 includes a movable cabinet door, which allows the receiving cavity 110 to be opened and closed for the installation and control of the first and second electrical components. For example, the cabinet door is opened and closed via hinges. Thus, since the distribution box 10 and the energy storage device 20 are connected, a certain amount of space needs to be left inside the energy storage device to allow for the cabinet door's movement. This occupies some space inside the energy storage device 20, relatively reducing the number of battery devices that the energy storage device 20 can accommodate, and making it difficult to increase the energy density of the energy storage device 20.

[0177] To address the aforementioned issues, as an optional implementation, the first surface 111 has an opening 1111, which is opposite to the first mounting area 210 along a first direction. At least a portion of the first electrical components pass through the opening 1111 and extend to the outside of the first surface 111, and at least a portion of the second electrical components pass through the opening 1111 and extend to the outside of the first surface 111. Thus, the first and second electrical components extend to the outside of the first surface 111, facilitating the control, installation, and maintenance of these components. Furthermore, the distribution box 10 does not require opening the cabinet door to operate the first electrical components, thereby reducing the space occupied by the distribution box 10. When the distribution box 10 and the energy storage device 20 are connected, the internal space of the energy storage device 20 is saved, and more battery devices are installed within the energy storage device 20, thereby improving the space utilization and energy density of the energy storage device 20.

[0178] In some embodiments, the number of openings 1111 can be one or more. When the number of openings 1111 is multiple, the openings 1111 and the internal extensions within the first electrical assembly are correspondingly provided.

[0179] In some embodiments, a third electrical component is disposed in a third mounting area 230. The third electrical component includes a plurality of switching power supplies and a first electrical device. The switching power supplies are all electrically connected to a first terminal 305 and a third terminal 308. A portion of the switching power supplies are electrically connected to the first electrical device. A portion of the switching power supplies are used to electrically connect to a second electrical device of the energy storage device 20.

[0180] It should be noted that the switching power supply in this embodiment can convert the input voltage into the voltage required by the first and second electrical devices. Specifically, the voltage required by the first and second electrical devices in this embodiment is DC 24V.

[0181] In some embodiments, the multiple switching power supplies include a first switching power supply 320 and a second switching power supply 321; the first switching power supply 320 is electrically connected to a first electrical device and at least a portion of the second electrical device; the second switching power supply 321 is electrically connected to the second electrical device.

[0182] In some implementations, see Figure 4 and Figure 5 The first switching power supply 320 and the second switching power supply 321 can be located in the third mounting area 230.

[0183] In some implementations, see Figure 7 and Figure 8 The first switching power supply 320 and the second switching power supply 321 can be located in the first mounting sub-area 231 of the third mounting area 230.

[0184] The first switching power supply 320 is connected in series with the relay. The first switching power supply 320 converts the 220V AC power input from the relay into 24V DC power and supplies it to the first electrical device in the distribution box 10, as well as the second electrical device in at least part of the energy storage device 20.

[0185] In this embodiment, the first electrical device includes: a surface cooler of the distribution box 10, a fan 400 of the distribution box 10, an electricity meter, etc.; the second electrical device includes: a surface cooler of the battery management system (BMS), a lighting system, an alarm bell, etc. These first and second electrical devices are electrically connected to the first switching power supply 320, and the corresponding input voltage is DC 24V.

[0186] The second switching power supply 321 is connected in series with the relay. The first switching power supply 320 converts the 220V AC power input from the relay into 24V DC power to supply the second power-consuming device in the energy storage device 20. For example, a combustible gas sensor installed inside the energy storage device 20.

[0187] In some embodiments, the third electrical component further includes a first uninterruptible power supply (UPS) 322 and a first battery 323, wherein the first UPS 322 is electrically connected to a first terminal block, a first electrical device, and a portion of a second electrical device; and the first battery 323 is electrically connected to the first UPS 322.

[0188] It should be noted that by setting up the first uninterruptible power supply 322, the distribution box 10 can immediately provide power to the first battery 323 when the mains power is suddenly interrupted, ensuring that the first and second electrical devices electrically connected to the first uninterruptible power supply 322 continue to operate, preventing data loss or equipment damage, thereby improving the safety of the distribution box 10 and the energy storage device 20.

[0189] It should be noted that the voltage output by the first uninterruptible power supply 322 in this embodiment is DC 24V.

[0190] In some embodiments, the second electrical component includes a second uninterruptible power supply 324 and a second battery 325. The second uninterruptible power supply 324 is electrically connected to the first terminal block 305, the second switching power supply 321, and a portion of the second electrical device. The second battery 325 is electrically connected to the second uninterruptible power supply 324.

[0191] In one specific embodiment, the second uninterruptible power supply 324 is connected in series between the relay and the second switching power supply 321, and the second battery 325 and the first terminal 305 are connected in parallel. Thus, by providing the second uninterruptible power supply 324, the distribution box 10 can immediately supply power to the second battery 325 when the mains power is suddenly interrupted, ensuring the continued operation of the second switching power supply 321 and the second electrical device electrically connected to the second uninterruptible power supply 324, as well as the first electrical device connected to the second switching power supply 321, thereby improving the safety of the distribution box 10 and the energy storage device 20.

[0192] It should be noted that the output voltage of the second uninterruptible power supply 324 in this embodiment is AC 220V.

[0193] In some embodiments, the first electrical component includes a plurality of controls, including a first control 303 and a second control 304. The first control 303 is electrically connected to a first uninterruptible power supply 322 to control the opening or closing of the first uninterruptible power supply 322. The second control 304 is electrically connected to a second uninterruptible power supply 324 to control the opening or closing of the second uninterruptible power supply 324.

[0194] The first control element 303 and the second control element 304 are disposed in the first mounting area 210. The first control element 303 and the second control element 304 pass through the opening 1111 and extend to the outside of the first surface 111 for user operation.

[0195] In some embodiments, the first electrical component includes an input terminal 301 and an output terminal 302. The input terminal 301 passes through the opening 1111 and extends to the outside of the first surface 111; the output terminal 302 passes through the opening 1111 and extends to the outside of the first surface 111. The second electrical component includes a circuit board 326, an industrial computer 327, and a switch 328. The circuit board 326, the industrial computer 327, and the switch 328 are electrically connected to the first uninterruptible power supply 322. The circuit board 326 is electrically connected to the industrial computer 327 and the switch 328. The input terminal 301, the circuit board 326, and the output terminal 302 are electrically connected to the switch 328.

[0196] Circuit board 326, industrial computer 327, and switch 328 are electrically connected to the first uninterruptible power supply 322 to ensure stable transmission of voltage, current, and signals. Industrial computer 327 and switch 328 are electrically connected to circuit board 326, thus forming a signal transmission channel between them.

[0197] In this embodiment, input terminal 301 is electrically connected to circuit board 326 to transmit different signals to industrial computer 327 and switch 328 via circuit board 326. Output terminal 302 is electrically connected to industrial computer 327 and switch 328 respectively to output signals from industrial computer 327 and switch 328.

[0198] It should be noted that by placing the third electrical component within the third mounting area 230, the third electrical component and the second electrical component are electromagnetically isolated by the separator 200, thereby improving the stability of signal transmission in the third electrical component.

[0199] The power distribution box 10 provided in this embodiment is applied to an energy storage device 20. The power distribution box 10 includes a housing 100, a partition 200, and at least two electrical components. The housing 100 has a receiving cavity 110; the receiving cavity 110 includes at least two mounting areas; the at least two electrical components are placed in different mounting areas. By placing the electrical components in the mounting areas, a modular installation design is formed within the mounting areas, which facilitates the installation and maintenance of the electrical components. It also improves the integration of the power distribution box 10. Each electrical component is concentrated in its corresponding mounting area, and the connections between the components are compact, reducing the space occupied by the power distribution box 10. Furthermore, it provides electrical isolation between electrical components in different mounting areas, reducing mutual interference between components and improving the operational stability of the power distribution box 10. In addition, when the power distribution box 10 and the energy storage device 20 are used together, the internal space occupied by the power distribution box 10 in the energy storage device 20 can be reduced, thereby increasing the number of battery devices within the energy storage device 20 and thus increasing the energy density of the energy storage device 20.

[0200] See Figure 11 In addition, this application embodiment also provides an energy storage device 20, including: a cabinet, a battery and a power distribution box 10 as described in the above embodiments. The power distribution box 10 is disposed in the cabinet and electrically connected to the battery.

[0201] It is easy to understand that the BMS in the battery can be electrically connected to the distribution box 10 via the input terminal 301. In addition, the distribution box 10 and the cabinet of the energy storage device 20 are detachably connected to facilitate the installation and maintenance of the distribution box 10.

[0202] In some embodiments, the energy storage device 20 also includes a second power supply device, which is electrically connected to the distribution box 10.

[0203] It should be noted that the electrical connection between the second electrical device and the distribution box 10 has been described in detail in the aforementioned embodiments, and will not be repeated here.

[0204] In some embodiments, the energy storage device also includes an air conditioner, which is electrically connected to the second terminal of the distribution box 10.
