[0018] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0019] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0021] In the battery energy storage system, the BSC controller, as its core component, undertakes the important task of monitoring and regulating the battery charging and discharging process to ensure the safety and efficient operation of the energy storage system. In the related art, the BSC controller shell mainly includes a top cover and a bottom plate formed by sheet metal processing. After assembly, a storage space is formed between the two to accommodate the electrical components that constitute the BSC controller. Generally, the electrical components of the BSC controller include components such as a battery management module, a power conversion module, a thermal management module, a safety protection device, a monitoring module, and a communication interface. The electrical connection relationship is established through a PCB (printed circuit board) to form a main control board. Then, a connection plate with connection holes and screws and fasteners are used to complete the assembly to reinforce the top cover and the bottom plate.

[0022] However, the applicant found that although the use of connecting plates with connecting holes and fasteners such as screws can provide the necessary physical support and protection for the top cover and the bottom plate, its design and assembly process also exposed some obvious problems. On the one hand, the additional connecting plate increases the total weight of the BSC controller, which is not only not conducive to lightweight design, but may also increase the side wall thickness of the controller housing, affecting the heat dissipation effect of the BSC controller. On the other hand, the assembly method using screw fastening not only increases the complexity and cost of production, but may also lead to extended assembly time, reduce production efficiency, and greatly reduce the practicality of the controller housing.

[0023] In view of this, the present application provides a controller housing, including a first cover plate 1 and a second cover plate 2, and the second housing is arranged above the first cover plate 1; side panels 3 are provided on the opposite sides of the first cover plate 1 and the opposite sides of the second cover plate 2, and the first cover plate 1 is covered on the second cover plate 2 through the side panels 3; the raised portion 4 and the embedded portion 5, the raised portion 4 and the embedded portion 5 are arranged opposite to each other, the raised portion 4 is protruding on the side of one of the side panels 3 of the first cover plate 1 and the side panels 3 of the second cover plate 2, and the embedded portion 5 is recessed on the other side, and the raised portion 4 is adapted to the embedded portion 5.

[0024] Specifically, see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the controller housing in this application. Figure 2 This is a partial cross-sectional view of the controller housing in this application.

[0025] The present application provides a controller housing with a simple structure and easy to assemble, such as Figure 1 and Figure 2 As shown, the controller housing may include a first cover plate 1 and a second cover plate 2. The first cover plate 1 serves as the bearing body of the BSC controller and is used to protect the electrical components inside the BSC controller. The second cover plate 2 is arranged above the first cover plate 1 to shield and protect the electrical components. In addition, as shown in FIG. Figure 2 As shown, side panels 3 are provided on opposite sides of the first cover plate 1 and opposite sides of the second cover plate 2, and the first cover plate 1 is covered on the second cover plate 2 through the side panels 3, that is, the first cover plate 1 can be connected to the side panels 3 of the second cover plate 2 through its side panels 3 by plugging or the like, thereby forming the main part of the controller housing.

[0026] As for the controller housing, in order to improve the firmness of the connection between the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2, as shown in FIG. Figure 2 As shown, a protrusion 4 can be provided on one of the side panels 3 of the first cover plate 1 and the side panels 3 of the second cover plate 2, and a fitting portion 5 adapted to the protrusion 4 can be provided on the other side panel. The protrusion 4 can be provided on the surface of one of the side panels 3, and the fitting portion 5 can be provided on the surface of the other side panel 3. The protrusion 4 and the fitting portion 5 are provided relative to each other, so that when the side panels 3 of the first cover body and the side panels 3 of the second cover body are connected, the protrusion 4 can be embedded in the inside of the fitting portion 5, and the fitting portion 5 is used to limit the position of the protrusion 4, so that the protrusion 4 and the fitting portion 5 are engaged with each other, and the side panels 3 of the first cover plate 1 and the side panels 3 of the second cover plate 2 are tightly connected.

[0027] For example, Figure 2As shown, the raised portion 4 is provided on the surface of the side plate 3 of the first cover plate 1, and the engaging portion 5 is provided on the surface of the side plate 3 of the second cover plate 2. When assembling the controller housing, the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2 can be plugged into each other until the raised portion 4 on the surface of the side plate 3 of the first cover plate 1 corresponds to the engaging portion 5 on the surface of the side plate 3 of the second cover plate 2. When the raised portion 4 is embedded in the engaging portion 5, the raised portion 4 and the engaging portion 5 are engaged with each other, so that the first cover plate 1 and the second cover plate 2 are locked with each other, thereby completing the assembly of the controller housing.

[0028] From the above, it can be seen that the controller housing provided in the present application is beneficial to reducing the complexity and assembly difficulty of the controller housing, shortening the assembly time, and improving the assembly efficiency by setting a protrusion 4 on the side of one of the side panels 3 of the first cover plate 1 and the side panels 3 of the second cover plate 2, and setting a fitting portion 5 at the corresponding position of the other side panel 3; in addition, since the controller housing omits the side panels 3 and fasteners such as screws, it can not only reduce the overall thickness of the side wall of the controller housing to ensure a good heat dissipation effect, but also significantly reduce the production cost, and therefore has good practicality.

[0029] The first cover plate 1 and the second cover plate 2 are further explained in combination with the above embodiment; as for the first cover plate 1, the first cover plate 1 and the side plate 3 connected thereto can be integrally formed using a sheet metal process, and the two are perpendicular to each other; similarly, as for the second cover plate 2, the second cover plate 2 and the side plate 3 connected thereto can also be integrally formed using a sheet metal process, and the two are also perpendicular to each other, so that a controller housing with a regular shape can be assembled through the first cover plate 1 and the second cover plate 2 and their respective side plates 3.

[0030] The raised portion 4 and the engaging portion 5 are further explained in conjunction with the above embodiment; since the first cover plate 1 and its side plate 3, and the second cover plate 2 and its side plate 3 are all integrally formed, a stamping process can be used to form the raised portion 4 on the surface of the side plate 3, and a stamping process can be used to form the engaging portion 5 on the surface of the side plate 3, and the engaging portion 5 can be a concave structure or an open structure to ensure that the raised portion 4 and the engaging portion 5 can be docked and clamped.

[0031] In some embodiments, the first cover plate 1 is further provided with a first mounting portion 8 . The first mounting portion 8 and the first cover plate 1 are located in the same plane, and a through hole 9 is formed in the first mounting portion 8 .

[0032] Specifically, see Figure 3 , Figure 3 This is a side view of the controller housing in this application.

[0033] As for the BSC controller, the controller housing is the main body of the BSC controller and is used to protect the electrical components in the BSC controller so that the BSC controller can be used in relatively complex environments; Figure 1 and Figure 3 As shown, in order to install the BSC controller to a preset installation position, a first mounting portion 8 can be provided on the first cover plate 1, and a through hole 9 can be opened in the first mounting portion 8 so that the controller housing can be tightened to the preset installation position by fasteners such as screws; in addition, by arranging the first mounting portion 8 and the first cover plate 1 in the same plane, the difficulty of manufacturing the first mounting portion 8 in the controller housing can be reduced. Specifically, since the first cover plate 1 is formed by sheet metal processing, the first cover plate 1 and the first mounting portion 8 can be integrally formed, thereby reducing the manufacturing cost of the controller housing.

[0034] In some embodiments, a plurality of first mounting portions 8 are provided, and there are at least two first mounting portions 8 distributed diagonally.

[0035] As for the first mounting portion 8, by providing the first mounting portion 8 on the controller housing, the controller housing can be fixedly connected to a preset mounting position; Figure 1 As shown, by providing a plurality of first mounting portions 8 on the controller housing, the firmness and reliability of the controller housing at the preset installation position can be improved; more specifically, among the plurality of first mounting portions 8, by arranging at least two first mounting portions 8 diagonally, the overall stability of the controller housing can be improved, thereby avoiding the problem of poor stability of the controller housing due to uneven distribution of the fixed areas.

[0036] In some embodiments, the side plate 3 of the second cover plate 2 is provided with a second mounting portion 10, which extends in a direction away from the second cover plate 2 and abuts against one side of the first mounting portion 8; the second mounting portion 10 is provided with a through hole 9, and the through hole 9 of the second mounting portion 10 coincides with the through hole 9 of the first mounting portion 8 in its orthographic projection on the first mounting portion 8.

[0037] As for the controller housing, by providing a first mounting portion 8 on the controller housing, the controller housing can be fixedly connected to a preset mounting position; Figure 1 and Figure 3 As shown, in addition to the first mounting portion 8, the side plate 3 of the second cover 2 of the controller housing is also provided with a second mounting portion 10. By extending the second mounting portion 10 in a direction away from the second cover 2 and abutting against one side of the first mounting portion 8, the second mounting portion 10 and the first mounting portion 8 can be overlapped; and the second mounting portion 10 is provided with a through hole 9, and the through hole 9 of the second mounting portion 10 coincides with the through hole 9 of the first mounting portion 8 in the orthographic projection of the first mounting portion 8, so that the first mounting portion 8 and the second mounting portion 10 can be fixed by the same fasteners such as screws, which can not only fix the controller housing to a preset installation position, but also reinforce the space between the first cover 1 and the second cover 2.

[0038] In some embodiments, a plurality of second mounting portions 10 are provided, and any second mounting portion 10 corresponds to a first mounting portion 8 .

[0039] As for the controller housing, the first mounting portion 8 and the second mounting portion 10 of the controller housing abut against each other, and the through holes 9 of the two overlap with each other, so that the controller housing can be firmly fixed to the preset installation area by fasteners such as screws, and the first cover plate 1 and the second cover plate 2 can also be reinforced; Figure 1 and Figure 3 As shown, by providing a plurality of second mounting portions 10 in the controller housing and making each second mounting portion 10 correspond to a first mounting portion 8, it is beneficial to further improve the firmness of the connection between the first cover plate 1 and the second cover plate 2, and ensure that the controller has better refinement.

[0040] In some embodiments, the raised portion 4 has at least one of the following features:

[0041] Along the protruding direction of the protruding portion 4, the height of the protruding portion 4 is less than or equal to the height of the fitting portion 5;

[0042] Along the protruding direction of the protrusion 4, the cross section of the protrusion 4 is in the shape of an arc;

[0043] Along the extending direction of the side plate 3 , a plurality of protrusions 4 and a plurality of engaging portions 5 are provided.

[0044] For example, in some cases, along the protruding direction of the protruding portion 4 , the height of the protruding portion 4 is less than or equal to the height of the fitting portion 5 .

[0045] As for the protrusion 4 and the fitting portion 5, by providing the protrusion 4 on the side of the side plate 3 of one of the first cover plate 1 and the second cover plate 2 and providing the fitting portion 5 on the side of the other side plate 3, the side plate 3 of the assembled first cover plate 1 and the side of the second cover plate 2 can be clamped and fixed to each other, which is conducive to reducing the difficulty of assembling the controller housing and improving the assembly efficiency; Figure 2 As shown, along the protruding direction of the protrusion 4, by setting the height of the protrusion 4 to be less than or equal to the height of the fitting portion 5, the protrusion 4 can be fully embedded in the fitting portion 5, and the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2 can be fully fitted in the connected state, which is beneficial to improving the firmness and reliability of the controller housing after assembly.

[0046] For example, in some cases, along the protruding direction of the protrusion 4 , the cross section of the protrusion 4 is in the shape of an arc.

[0047] As for the raised portion 4, when the controller housing is assembled, the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2 slide relative to each other until the raised portion 4 on the surface of one side plate 3 slides into the fitting portion 5 on the surface of the other side plate 3, so that the raised portion 4 and the fitting portion 5 are clamped to each other; Figure 2 As shown, along the protruding direction of the protrusion 4, by setting the cross section of the protrusion 4 to an arc shape, the wear of the edges of the protrusion 4 and the fitting part 5 during the assembly of the controller housing can be reduced, and the smoothness of the engagement between the protrusion 4 and the fitting part 5 can be improved.

[0048] In addition, when repairing the BSC controller, the first cover and the second cover in the controller housing need to be disassembled, so the protrusion 4 needs to be slid out of the fitting portion 5; by setting the cross-section of the protrusion 4 to an arc shape, the degree of obstruction between the protrusion 4 and the fitting portion 5 can be reduced, which is conducive to reducing the difficulty of disassembling the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2.

[0049] For example, in some cases, a plurality of protrusions 4 and a plurality of engaging portions 5 are provided along the extending direction of the side plate 3 .

[0050] As for the controller housing, a protrusion 4 is provided on the side plate 3 of one of the first cover plate 1 and the second cover plate 2, and a fitting portion 5 is provided on the side of the other cover plate, so that the first cover plate 1 and the second cover plate 2 can be assembled through the side plate 3; wherein, along the extension direction of the side plate 3, a plurality of protrusions 4 and fitting portions 5 are provided on the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2, and any protrusion 4 is provided opposite to a fitting portion 5, so that the snap-fit ​​effect of the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2 can be improved, thereby avoiding the occurrence of local loose splicing and affecting the reliability of the controller housing.

[0051] In some embodiments, the side panel 3 of the first cover plate 1 is provided with a first bending portion 6 and a second bending portion 7 connected to each other, the first bending portion 6 is bent toward the direction of the side panel 3 close to the second cover plate 2, and the bending direction of the second bending portion 7 is opposite to the bending direction of the first bending portion 6, so that a portion of the side panel 3 of the first cover plate 1 is flush with the side panel 3 of the second cover plate 2; and / or the side panel 3 of the first cover plate 1 and the side panel 3 of the second cover plate 2 are both provided with a groove 11, and the groove 11 of the side panel 3 of the first cover plate 1 is set toward the second cover plate 2 and is opposite to the groove 11 of the side panel 3 of the second cover plate 2.

[0052] As for the controller housing, since the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2 are connected by the protrusion 4 and the interlocking portion 5, the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2 are stacked along the protruding direction of the protrusion 4; Figure 2As shown, with regard to the side panel 3 of the first cover plate 1, the side panel 3 of the first cover plate 1 is provided with a first bending portion 6 and a second bending portion 7 that are connected to each other, wherein, by bending the first bending portion 6 toward the direction of the side panel 3 close to the second cover plate 2, and making the bending direction of the second bending portion 7 opposite to the bending direction of the first bending portion 6, a portion of the side panel 3 of the first cover plate 1 can be made flush with the side panel 3 of the second cover plate 2, so that the outer side wall of the controller housing is relatively flat and smooth, thereby improving the overall aesthetics of the controller housing.

[0053] In addition, since the first bending portion 6 is bent toward the direction of the side panel 3 close to the second cover plate 2, the bending direction of the second bending portion 7 is opposite to the bending direction of the first bending portion 6, so that the first bending portion 6 and the second bending portion 7 form a limiting structure on the side of the first cover plate 1. When the side panel 3 of the first cover plate 1 is assembled and connected with the side panel 3 of the second cover plate 2, the two side panels 3 are stacked and slide relative to each other. At this time, the limiting structure formed by the second bending portion 7 of the side panel 3 of the first cover plate 1 can limit the stroke of the side panel 3 of the second cover plate 2, avoiding the side panel 3 of the second cover plate 2 from having too large a stroke and causing the overlapping area between the two to be too large, so as to ensure that the internal space of the controller housing is relatively sufficient.

[0054] As for the BSC controller, the electrical components that make up the BSC controller are located in the controller housing. Since the BSC controller needs to be electrically connected to the battery modules and other electronic control devices in the energy storage system, the communication interface of the BSC controller can be used as the wiring terminal 13 of the BSC controller. In order to facilitate wiring and maintenance of the BSC controller, the wiring terminal 13 of the BSC controller can be exposed relative to the controller housing. Figure 1 and Figure 3 As shown, grooves 11 can be respectively provided on the side panels 3 of the first cover plate 1 and the side panels 3 of the second cover plate 2, wherein, as for the side panels 3 of the first cover plate 1, the opening of the groove 11 is arranged toward the second cover plate 2 and is opposite to the opening of the groove 11 of the side panels 3 of the second cover plate 2. When the first cover plate 1 and the second cover plate 2 are spliced ​​together through the side panels 3, the grooves 11 of the side panels 3 of the first cover plate 1 and the grooves 11 of the side panels 3 of the second cover plate 2 can be spliced ​​into a square opening and can surround the wiring terminals 13. Therefore, by providing the grooves 11 on the side panels of the first cover plate 1 and the side panels of the second cover plate 2, the wiring terminals 13 can be accommodated, thereby ensuring that the wiring terminals 13 can be exposed to the outside, and at the same time, it will not interfere with or hinder the assembly of the side panels 3 of the first cover plate 1 and the side panels 3 of the second cover plate 2, which is conducive to achieving precise docking and rapid assembly of the first cover plate 1 and the second cover plate 2.

[0055] Based on the same inventive concept, the present application also provides a controller, including a controller housing as described above, and also including a main control board 12, which is arranged inside the controller housing and fixedly connected to the first cover plate 1; the main control board 12 is provided with a wiring terminal 13, and the wiring terminal 13 passes through the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2, and the wiring terminal 13 is exposed relative to the controller housing; on the one hand, since the controller has the controller housing of the above embodiment, the controller has all the advantages and beneficial effects of the controller housing in the above embodiment, which will not be repeated here.

[0056] On the other hand, as far as the controller is concerned, in addition to the controller housing, the controller also includes a main control board 12. The main control board 12 is arranged inside the controller housing and is protected by the controller housing; the main control board 12 can be fixed to one side of the first cover plate 1 by fasteners such as screws, providing an installation position for the main control board 12 and improving the firmness and stability of the main control board 12 in the controller housing; as for the wiring terminal 13, on one side of the controller housing, the wiring terminal 13 passes through the side plate 3 of the first cover plate 1 and the side plate 3 of the second cover plate 2, so that the wiring terminal 13 is exposed relative to the controller housing, which is convenient for wiring the controller and establishing an electrical connection relationship with external equipment, thereby reducing the difficulty of wiring the controller.

[0057] Based on the same inventive concept, the present application also provides a battery, including the controller described in the above embodiment; since the battery has the above-mentioned controller, the battery has all the advantages and beneficial effects of the above-mentioned controller; illustratively, the battery using the controller mentioned in the above embodiment can be one of a lithium-ion battery, a lead-acid battery, a nickel-cadmium battery, a nickel-hydrogen battery, a sodium-sulfur battery and a hydrogen fuel cell, which will not be repeated here.

[0058] Based on the same inventive concept, the present application also provides a vehicle, including a controller as described in the above embodiment, and / or a battery as described in the above embodiment; since the vehicle has the above-mentioned controller and / or battery, the vehicle has all the advantages and beneficial effects of the above-mentioned controller and / or battery, which will not be repeated here.
