[0063] In the following, the embodiments of the present application are described in detail.

[0064] New energy technology is more and more widely used in life and industry, for example, new energy technology has been widely used in the automobile industry, in addition, new energy technology is also more and more widely used in the field of energy storage and the like. At present, higher requirements are put forward for the efficient use of space in the energy storage device. When optimizing the use of space, the layout of the pipe fittings also needs to be optimized, and sometimes the pipe fittings need to be arranged through the partition. How to improve the disassembly and assembly convenience of the pipe fittings arranged through the partition is one of the problems to be solved.

[0065] In the energy storage device, for example, a battery compartment, an electrical compartment, etc. can be included. The battery compartment can accommodate a plurality of battery devices, and input and output ends of the plurality of battery devices are connected to a power source, a power grid, an electrical device, etc. through a bus assembly. The electrical compartment can accommodate a power distribution cabinet for performing power distribution control, etc.

[0066] In the related art, the bus assembly occupies the space of the battery compartment, resulting in a large waste of space and being not conducive to improving the volumetric energy density. For example, the bus assembly is arranged in the electrical compartment to make full use of the space of the electrical compartment. In addition, considering that the bus assembly arranged in the electrical compartment can interfere between high-voltage and low-voltage electrical elements (for example, interference caused by current, magnetic field, etc.) and the convenience of maintenance work of the bus assembly, a partition is arranged in the electrical compartment to divide the electrical compartment into a first chamber and a second chamber. However, the electrical compartment also has a pipe arranged therein, and the pipe extends through the first chamber and the second chamber. Therefore, the pipe needs to pass through the partition. In the case of limited space, especially in the case that the partition is not easy to be disassembled relative to the wall of the box, it is difficult to pass the pipe from one side of the partition to the other side. Therefore, how to easily realize the disassembly and assembly of the pipe is one of the problems to be solved.

[0067] To solve the above problems, the energy storage device provided by the embodiments of the present application includes a box body, the box body defines an accommodation space, a partition is arranged in the accommodation space, along a first direction, a first chamber is arranged on one side of the partition, and a second chamber is arranged on the other side of the partition. The first direction is consistent with the thickness direction of the partition. The partition is formed with a first opening and is configured to be partially closed or opened relative to the first opening. In the opened state of the first opening, the first chamber and the second chamber are in communication. The partition is provided with a mounting slot. The mounting slot penetrates the partition along the first direction and is provided with a slot opening facing the first opening and in communication with the first opening. The mounting slot is used for mounting a pipe penetrating the partition.

[0068] Since the partition is provided with the mounting slot penetrating the partition and the slot opening of the mounting slot faces the first opening, the pipe can be pushed into the mounting slot from the first opening side through the slot opening. Therefore, the pipe penetrating the partition can be easily realized, and even long pipes can be dealt with, which has the advantage of convenient disassembly and assembly of the pipe.

[0069] The energy storage device provided by the embodiments of the present application can be used in energy storage power stations, wind power systems, solar power systems, mobile power systems, or temporary power supply systems, etc. The energy storage device can store electrical energy as needed and output electrical energy at appropriate times.

[0075] In some embodiments, a battery apparatus can be a battery pack including an outer case and one or more battery cell assemblies housed in the outer case.

[0076] As an example, a battery cell assembly can be a battery module, and the battery cell assembly can be housed in the outer case by fixing the battery module in the outer case.

[0077] As an example, a battery cell assembly can also be housed in the outer case by directly fixing a plurality of battery cells in the outer case.

[0078] As an example, the outer case can include a first outer case and a second outer case. The first outer case and the second outer case are coupled to form a closed space inside the outer case to accommodate the battery cell assembly. Here, closed means covered or closed, which can be sealed or unsealed. The first outer case can be a top cover or a bottom plate.

[0079] In some embodiments, the energy storage device can include a thermal management module, a master control module, a general control module, a power distribution module, and a fire extinguishing system.

[0085] In the following, the detailed description of some embodiments of the present application is given with reference to the accompanying drawings. Figures 1 to 6 The detailed description of some embodiments of the present application is given below. Figure 1 The structure schematic diagram of the energy storage device provided by some embodiments of the present application is shown in the following figure: Figure 2 The structure schematic diagram of the partition provided by some embodiments of the present application is shown in the following figure: Figure 3 The structure schematic diagram of the partition provided by some embodiments of the present application is shown in the following figure:

[0086] The energy storage device provided by the embodiments of the present application is shown in the following figure: Figures 1 to 6As shown, the box 10 defines a containing space, in which a partition 40 is arranged, and along a first direction Z, a first chamber 121 is arranged on one side of the partition 40, and a second chamber 122 is arranged on the other side of the partition 40, wherein the first direction Z is consistent with the thickness direction of the partition 40; the partition 40 is formed with a first opening 41a and is configured to be partially closed or opened relative to the first opening 41a, in the state that the first opening 41a is opened, the first chamber 121 and the second chamber 122 are communicated, the partition 40 is provided with a mounting groove 401, the mounting groove 401 penetrates the partition 40 along the first direction Z and a groove opening 402 is arranged towards and communicated with the first opening 41a; the mounting groove 401 is used for mounting a pipe 70 penetrating the partition 40.

[0087] The box 10 is used to define a containing space, which is used to contain the components of the energy storage device. The containing space provided by the box 10 can be generally divided into a battery cabin 11 and an electrical cabin 12, the battery cabin 11 is mainly used to accommodate a battery cluster (including a plurality of battery devices), and the electrical cabin 12 is mainly used to accommodate at least part of a master control module, a general control module, a power distribution module and a fire-fighting module.

[0088] The plurality of battery devices in the battery cabin 11 can be electrically connected through busbar assemblies 20. As an example, the plurality of battery devices are connected in series through the busbar assemblies to improve the voltage of the energy storage device. When the energy storage device includes a plurality of battery clusters, the plurality of battery clusters are connected in parallel through the busbar assemblies to improve the capacity of the energy storage device. These busbar assemblies further electrically connect the battery devices with the power supply system and the electrical equipment. In the embodiments of the present application, at least part of the busbar assemblies are arranged in the electrical cabin 12.

[0089] Of course, the containing space provided by the box 10 can be further divided into other cabins, such as a cooling cabin, etc. The partition 40 can be arranged in the battery cabin, the electrical cabin, the cooling cabin or other required cabin, and the embodiments of the present application take the partition 40 arranged in the electrical cabin 12 as an example for description.

[0090] The electrical compartment 12 is equipped with a partition 40, which divides the electrical compartment 12 into a first chamber 121 and a second chamber 122. Electrical control components, including a distribution cabinet 30 with a power distribution switch, are arranged in the second chamber 122, while a busbar assembly 20 is arranged in the first chamber 121. This embodiment does not impose any particular limitations on the distribution cabinet 30 and the busbar assembly 20; existing methods can be used. The electrical control components may also include fire control components, etc. The distribution cabinet 30 located in the second chamber 122 may have a door, or it may not have a door, or it may be a distribution panel with a power distribution switch, etc. Typically, the busbar assembly 20 is a high-voltage component, and the distribution cabinet 30 is a low-voltage component. During operation, electromagnetic interference may occur between the two, potentially adversely affecting the stable operation of the energy storage device. Isolating the busbar assembly from the distribution cabinet 30 through the partition 40 effectively reduces electromagnetic interference.

[0091] Furthermore, the first chamber 121 and the second chamber 122 can be connected. For example, a first opening 41a can be provided, and the two chambers can be separated by closing the first opening 41a with a partition 40. Additionally, the partition 40 can be configured to be partially open relative to the first opening 41a. In the open state, operators or tools can extend from the second chamber 122 into the first chamber 121 to perform installation, maintenance, or other operations. For example, the partition 40 can be detachably connected to the first opening 41a; or, the partition can be partially rotated and opened / closed relative to the first opening 41a to open the first opening 41a.

[0092] A mounting groove 401 is provided in the portion of the partition 40 where the first opening 41a is not formed. The mounting groove 401 extends through the partition 40 along a first direction Z (the thickness direction of the partition 40). The mounting groove 401 has a notch 402, which is provided facing and communicating with the first opening 41a. Figure 5 In the illustrated embodiment, the mounting groove 401 extends along the second direction Y, and the groove wall of the mounting groove 401 is generally U-shaped. The mounting groove 401 is used to install the pipe fitting 70 that passes through the separator 40. The groove width of the mounting groove 401 (as shown in the figure) Figure 5 For example, the dimension of the mounting groove 401 along the third direction X can be formed to provide a clearance fit or an interference fit with the outer diameter of the fitting 70 to be installed. The groove depth of the mounting groove 401 (in the third direction X) Figure 5 For example, the dimensions of the mounting groove 401 along the second direction Y can be formed to be larger than or approximately the same as the outer diameter of the pipe fitting 70 to be installed, so that the pipe fitting 70 does not protrude from the groove 402 into the mounting groove 401.

[0093] The fitting 70 can be a liquid pipe or a vent pipe in the energy storage device, and this application embodiment does not limit it. In some embodiments, the fitting 70 is a fire-fighting water pipe equipped in the energy storage device.

[0094] When installing the fitting 70, the first opening 41a is opened, and the fitting 70 is inserted into the first opening 41a. Since the first opening 41a can be made relatively large, it is relatively easy to insert the fitting 70 through the separator 40. Then, the fitting 70 is inserted into the mounting groove 401 through the slot 402 communicating with the first opening 41a, thereby installing the fitting 70 in the mounting groove 401. Then, the first opening 41a can be closed, thereby preventing the fitting 70 from coming out of the slot 402 of the mounting groove 401.

[0095] The electrical compartment 12 is divided into a first chamber 121 and a second chamber 122 by the partition 40. The busbar assembly 20 is located in the first chamber 121, and electrical control components such as the distribution cabinet 30, which includes a power distribution switch, are located in the second chamber 122. This allows for full utilization of the electrical compartment 12, improves the compactness of the layout of each component within the electrical compartment 12, and helps to increase the space ratio of the battery compartment 11, thereby increasing the volumetric energy density of the energy storage device. Furthermore, the partition 40 is configured to allow the first opening 41a to be closed or opened, thereby isolating the busbar assembly 20 from the electrical control components such as the distribution cabinet, which includes a power distribution switch, to reduce mutual interference of current, magnetic fields, etc., and to reduce the risk of electric shock when operating the electrical control components such as the power distribution switch. In addition, the busbar assembly 20 can be maintained through the first opening 41a, improving maintenance convenience. Since the partition 40 has a mounting groove 401 that passes through the partition 40 and the groove 402 of the mounting groove 401 is set facing the first opening 41a, the pipe 70 can be pushed into the mounting groove 401 from the first opening side through the groove 402, so that the pipe 70 can be easily inserted into the partition 40, even long pipes can be accommodated, and it has the advantage of convenient pipe assembly and disassembly.

[0096] In some embodiments, the first chamber 121 and the second chamber 122 at least partially overlap along a first direction Z, wherein the first direction Z is perpendicular to the bearing surface for supporting the energy storage device.

[0097] As an example, such as Figure 1 As shown, the electrical compartment 12 is located at the end of the housing 10 and is arranged side by side with the battery compartment 11. Inside the electrical compartment, the partition 40 divides the electrical compartment 12 into a first chamber 121 and a second chamber 122 distributed along the first direction Z (which can be regarded as the height direction of the housing 10). The first chamber 121 and the second chamber 122 may partially or completely overlap along the first direction Z.

[0098] In some embodiments, the second chamber 122 is located above the first chamber 121. In other embodiments, the second chamber 122 occupies a larger space in the first direction Z than the first chamber 121 occupies in the first direction Z.

[0099] Thus, the space in the height direction of the electrical cabin 12 can be fully utilized, which is conducive to increasing the space proportion of the battery cabin 11 and improving the volumetric energy density of the energy storage device.

[0100] In some embodiments, a pipe locking accessory 44 is arranged on one side and / or the other side of the partition 40 along the first direction Z, the pipe locking accessory 44 is provided with a limiting hole 443 for the pipe 70 to pass through, and the pipe locking accessory 44 is detachably connected to the partition 40 and the limiting hole 443 overlaps with the mounting groove 401.

[0101] As shown in Figures 1 to 6 The pipe locking accessory 44 is, for example, a plate member, and the shape viewed along the first direction Z is not particularly limited and can be circular, rectangular, etc. The pipe locking accessory 44 is provided with a limiting hole 443, which is a through hole penetrating through along the first direction Z. The inner peripheral contour of the limiting hole 443 is formed only to allow the pipe 70 to be arranged to pass through and to have a limiting effect on the pipe 70. For example, the limiting hole 443 can be formed in a circular shape and tangent to the outer contour of the pipe 70. The limiting hole 443 can also be formed in a triangular shape, quadrilateral shape or polygonal shape and tangent to the outer contour of the pipe 70. In a specific example, the pipe 70 has a cylindrical outer peripheral surface, and the limiting hole 443 is formed to have a cylindrical inner peripheral surface, and the outer peripheral surface of the pipe 70 cooperates with the inner peripheral surface of the limiting hole 443 in a contact manner.

[0102] The pipe locking accessory 44 is detachably mounted to the partition 40, for example, on the surface of the partition 40 located on one side of the second chamber 122. The connection manner can be threaded connection, riveting, etc.

[0103] Due to the addition of the pipe locking accessory, the partition around the mounting groove can be strengthened, and the installation stability of the pipe can be improved.

[0104] The pipe locking accessory 44 can be made of metal, alloy or resin.

[0105] Due to the addition of the pipe locking accessory 44 at the part of the partition 40 where the mounting groove 401 is arranged, the partition 40 around the mounting groove 401 can be strengthened, and the installation stability of the pipe 70 can be improved.

[0106] In some embodiments, the partition 40 includes a partition plate, and the partition plate includes a partition plate body 41 and a cover plate 42, the partition plate body 41 is arranged in the box body 10, the partition plate body 41 is formed with a first opening 41a, the mounting groove 401 is arranged in the partition plate body 41, and the cover plate 42 is connected to the partition plate body 41 and is configured to close or open the first opening 41a.

[0107] The partition body 41 can be connected (e.g., fixedly connected) to the box body 10, for example, by welding or bolting to the box body 10. The mounting groove 401 is provided on the partition body 41, and the groove opening 402 of the mounting groove 401 is located at the side edge of the partition body 41 facing the first opening 41a (or the cover plate 42 in the closed state). In other words, part of the side edge of the partition body 41 facing the first opening 41a (or the cover plate 42 in the closed state) is recessed in the direction away from the first opening 41a (or the cover plate 42 in the closed state) along the second direction Y to form the mounting groove 401.

[0108] The cover plate 42 is detachably connected or hingedly connected with the partition body 41. When the cover plate 42 is mounted on the partition body 41 and covers the first opening 41a, the cover plate 42 closes the first opening 41a, thereby isolating the first chamber 121 and the second chamber 122. When the cover plate 42 is detached from the partition body 41 or is rotated relative to the first opening 41a to be opened, the first opening 41a is opened, and the bus assembly 20 in the first chamber 121 can be installed, maintained, or the like through the first opening 41a. The pipe 70 can also be disassembled through the first opening 41a.

[0109] The cover plate 42 and the partition body 41 can be detachably connected by screw connection, buckle connection, or the like. The cover plate 42 and the partition body 41 can also be hingedly connected. The partition body 41 can have one or more first openings 41a. The first opening 41a can be surrounded by the partition body 41 and the surrounding wall of the box body, or can be surrounded by the partition body 41. As an example, as shown in Figure 2 and Figure 3 The partition body 41 can have a frame structure surrounding two first openings 41a distributed along the second direction Y of the box body 10. The cover plate 42 corresponding to each first opening 41a can be provided on the frame structure. The cover plate 42 can be provided with a handle for easy disassembly.

[0110] As an example, the material of the partition 40 can be metal, such as aluminum plate, steel plate, aluminum alloy plate, or the like. In some embodiments, the material of the partition 40 can also be non-metal, such as resin, or the like. Further, the partition 40 can be provided with electromagnetic shielding measures as needed.

[0111] The cover plate 42 and the partition body 41 are connected in such a way that the first opening 41a can be closed or opened. Therefore, it is not necessary to disassemble the partition body 41. The pipe 70 can be easily disassembled by simply opening the cover plate 42. When the bus assembly 20 needs to be installed or maintained, the cover plate 42 can be opened to facilitate the operation of the bus assembly 20, thereby improving the convenience of maintenance.

[0112] In some embodiments, as shown in Figure 5 andFigure 6 As shown, the pipe locking accessory has an extension 442, which includes a curved section 442a and a flat section 442b connected in sequence. The curved section 442a extends into the space between the first opening 41a and the slot 402 and covers the slot 402. The flat section 442b extends from the curved section 442a in a direction away from the slot 402 and contacts a side surface of the cover plate 42 that closes the first opening 41a.

[0113] As shown, the curved section 442a extends from the main body part (locking plate 441) of the pipe locking accessory in a curved manner, extending downward (toward the side where the first chamber 121 is located) in the drawing further away from the locking plate 441. The flat section 442b is connected to the end of the curved section 442a, and the upper surface of the flat section 442b in the drawing can be in surface contact with the surface of the cover plate 42 that is used to cooperate with the partition main body 41. The width of the extension 442 can be formed to be substantially the same as the slot 402, or can be formed to be wider than the slot 402. Figure 6 Figure 5 The curved section 442a of the extension 442 covers the slot 402, thus filling the missing part of the partition main body 41 at the slot 402, so as to reduce the risk of dust, water vapor, etc. entering from the slot 402. In addition, the flat section 442b is in contact with the cover plate 42, so that the flat section 442b and the partition main body 41 can form a continuous support surface that supports the cover plate 42, which is conducive to improving the sealing reliability of the cover plate to the first opening 41a.

[0114] Thus, the curved section 442a of the extension 442 covers the slot 402, thus filling the missing part of the partition main body 41 at the slot 402, so as to reduce the risk of dust, water vapor, etc. entering from the slot 402. In addition, the flat section 442b is in contact with the cover plate 42, so that the flat section 442b and the partition main body 41 can form a continuous support surface that supports the cover plate 42, which is conducive to improving the sealing reliability of the cover plate to the first opening 41a.

[0115] In some embodiments, as shown, a first seal 43 is provided on one side of the cover plate 42 in the first direction Z. The partition main body 41, the flat section 442b, and the first seal 43 are in contact, and the surface of the partition main body 41 that is in contact with the first seal 43 is flush with the surface of the flat section 442b that is in contact with the first seal 43. Figure 5

[0116] The first seal 43 can be provided, for example, at the edge region of the cover plate 42 that abuts against the partition main body 41. The first seal 43 can be, for example, a flat rubber seal. The first seal 43 can be fastened together with the cover plate 42 and the partition main body 41 by means of bolts or the like. The first seal 43 can also be bonded to the cover plate 42.

[0117] “flush” can be understood as substantially flush, i.e. the surface of the extension 442 facing the first seal 43 and the surface of the partition main body 41 facing the first seal 43 can be flush within the range allowed by installation errors and manufacturing errors, so that the first seal 43 is tightly pressed between the support surface formed by the extension 442 and the partition main body 41 and the cover plate 42.

[0118] ​​Due to the first sealing member 43, the risk of moisture, dust, etc. in the second chamber 122 entering the first chamber 121 through the gap between the cover plate 42 and the partition body 41 to cause the current collection assembly to be damp and short-circuit is reduced. Moreover, due to the flat section 442b and the partition body 41 and the first sealing member 43 forming a continuous sealing surface, the sealing performance between the cover plate 42 and the partition body 41 is not greatly reduced due to the installation groove, and the use reliability of the energy storage device is improved.

[0119] In addition, the first sealing member 43 can also be in a closed ring structure around the first opening 41a. The first sealing member 43 can be a rubber ring, a rubber filler, etc.

[0120] By arranging the first sealing member 43 between the partition body 41 and the cover plate 42, the first sealing member 43 is arranged around the first opening 41a, which can reduce the risk of condensed water, dust, etc. on the surface of the cover plate 42 entering the first chamber 121, thereby protecting the current collection assembly 20 and improving the stability of the energy storage device. For the first sealing member 43, it can be selected according to the actual situation, for example, a sealing member with a protection level of IP55 (see GB / T4208-2017) can be selected.

[0121] In some embodiments, along the first direction Z, a second sealing member 45 is arranged between the pipe locking accessory 44 and the partition body 41, and the second sealing member 45 is arranged around the limiting hole 443.

[0122] In the state that the second sealing member 45 is installed on the pipe 70, the second sealing member 45 is sleeved on the outer circumferential surface of the pipe 70. The second sealing member 45 can be in close contact with the outer circumferential surface of the pipe 70.

[0123] Therefore, the moisture, dust, etc. can be reduced from entering the first chamber 121 through the limiting hole 443 and the installation groove 401.

[0124] The second sealing member 45 can be a complete sealing member, or can be two split sealing members spliced together. The second sealing member 45 can be a rubber member or other member that can achieve a sealing effect.

[0125] In some embodiments, as shown in Figure 5 and Figure 6 The pipe locking accessory 44 includes a pair of split locking plate members (the locking plate members include a locking plate 441 and a protruding portion 442), and the pair of split locking plate members are installed on the partition 40 in a mutually opposite manner.

[0126] The pair of split locking plate members can be respectively installed on the partition 40, such as the partition body 41, by bolts or the like.

[0127] Therefore, the disassembly and assembly convenience of the pipe locking accessory 44 can be improved.

[0128] In some embodiments, as shown in Figure 5 Fig. 2, along the first direction Z, a second sealing member 45 is clamped between each locking plate member and the partition 40, and a pair of second sealing members 45 are arranged around the limiting hole 443 by being mutually opposed.

[0129] The pair of second sealing members 45 can be connected with each locking plate member and the partition 40 by means of bolts or adhesion.

[0130] In this way, the sealing performance can be improved while improving the disassembly convenience of the second sealing member 45.

[0131] In some embodiments, the partition body 41 comprises a first body portion 411 and a second body portion 412, the first body portion 411 and the second body portion 412 are respectively connected to the cabinet 10, and the first body portion 411 and the second body portion 412 are arranged in the second direction Y, the first opening 41a is located between the first body portion 411 and the second body portion 412, the cover plate 42 detachably covers the first opening 41a, the second direction Y is transverse to the first direction Z, and at least one of the first body portion 411 and the second body portion 412 is provided with a mounting groove 401.

[0132] In a specific embodiment, as shown in Figure 3 Fig. 3, two connecting portions 413 can be connected between the first body portion 411 and the second body portion 412, the first body portion 411, the second body portion 412 and the connecting portion 413 constitute a frame structure with the first opening 41a, and the first opening 41a is a ring-shaped closed opening. The partition body 41 can be fixed to the cabinet 10 through the first body portion 411 and the second body portion 412.

[0133] In another specific embodiment, the two connecting portions 413 described above can be part of the cabinet wall of the cabinet 10, that is, the first body portion 411 and the second body portion 412 are mounted on the cabinet wall of the cabinet 10 and jointly form the first opening 41a with the cabinet wall.

[0134] The end edges of the first body portion 411 and the second body portion 412 connected to the cabinet wall of the cabinet 10 can be mounted on the cabinet 10 by welding and / or threaded connection.

[0135] In a specific example as shown in Figure 2 Fig. 4, the mounting groove 401 is provided in one of the first body portion 411 and the second body portion 412.

[0136] Thus, in the case where the first main body portion 411 and the second main body portion 412 are fixedly connected to the case 10, the cover plate 42 can still be normally opened, and the maintenance, installation, and the like of the busbar assembly and the like can be easily performed via the first opening 41a. In some embodiments, a first seal member 43 is provided between the partition plate main body 41 and the cover plate 42, and the first seal member 43 is provided around the first opening 41a. In addition, the pipe 70 can be arranged as needed, and since the pipe 70 is arranged in the case near the side wall, the regularity of the pipe arrangement and the degree of freedom of use of the space other than the space occupied by the pipe can be improved.

[0137] In some embodiments, the cover plate 42 includes a cover plate main body and a thermal insulation layer, and the thermal insulation layer is laminated to the cover plate main body.

[0138] The cover plate main body can be configured to have two surfaces facing each other in the thickness direction, and the thermal insulation layer can be laminated to any one of the surfaces or both of the surfaces. The thermal insulation layer can be laminated to the entire surface of the cover plate main body, or can be laminated to a part of the surface of the cover plate main body.

[0139] Thus, the heat generated in the first chamber 121 can be suppressed from spreading to the second chamber 122 by the thermal insulation layer, and the risk of condensation water being generated on the surface of the cover plate 42 on the side facing the second chamber can be reduced.

[0140] In some embodiments, the thermal insulation layer is laminated to the surface of the cover plate 42 on the side facing the first chamber 121 in the state where the first opening 41a is closed. In some embodiments, the thermal insulation layer includes a polyurethane layer.

[0141] In some specific embodiments, the bottom surface of the cover plate 42 on the side facing the first chamber 121 is provided with a polyurethane coating.

[0142] As an example, the polyurethane coating can be applied to the bottom surface of the cover plate 42 by spraying. The polyurethane coating provided on the bottom surface of the cover plate 42 not only has the effect of preventing condensation water, but also has the effect of thermal insulation.

[0143] In some embodiments, the first main body portion 411 is provided with a first through-hole 411a for communicating the first chamber 121 and the second chamber 122, and / or the second main body portion 412 is provided with a second through-hole 412a for communicating the first chamber 121 and the second chamber 122.

[0144] The first through-hole 411a provided in the first main body portion 411 can communicate the first chamber 121 and the second chamber 122, and the first through-hole 411a can be used for the passage of a wire or a pipe, and the like.

[0145] The second through hole 412a provided by the second body part 412 can communicate the first chamber 121 and the second chamber 122, and can be used for passing a wire or a pipeline, etc.

[0146] For example, the wire can include an electric cable, etc., and the pipeline can include a cooling liquid pipeline, etc.

[0147] Since the first body part 411 and the second body part 412 are provided with through holes for passing wires or pipelines, the through holes can be used to pass electric wires, fluid pipelines, etc. through the partition, facilitating the layout of the wires and pipelines. Moreover, the wires and pipelines, etc. can be arranged near the walls of the cabinet on the side of the through holes, which is conducive to improving the compactness and regularity of the wiring. Moreover, when the cover plate 42 is removed for maintenance of the busbar assembly 20, the wiring or pipeline passing through the through hole is not affected, improving the convenience of maintenance.

[0148] In some embodiments, the first body part 411 is provided with a first enclosing structure 411b arranged around at least part of the entire circumference of the first through hole 411a; and / or, the second body part 412 is provided with a second enclosing structure 412b arranged around at least part of the entire circumference of the second through hole 412a.

[0149] For example, as shown in Figs. 4 and 5, the first enclosing structure 411b can be arranged around the first through hole 411a in a manner of leaving a gap, and the gap is away from the first opening 41a, for example, towards the side wall of one side of the cabinet 10. The second enclosing structure 412b can be arranged around the second through hole 412a in a manner of leaving a gap, and the gap is away from the first opening 41a, for example, towards the side wall of the other side of the cabinet 10. Figure 2 Figure 3 For example, as shown in Figs. 4 and 5, the first enclosing structure 411b can be arranged around the first through hole 411a in a manner of leaving a gap, and the gap is away from the first opening 41a, for example, towards the side wall of one side of the cabinet 10. The second enclosing structure 412b can be arranged around the second through hole 412a in a manner of leaving a gap, and the gap is away from the first opening 41a, for example, towards the side wall of the other side of the cabinet 10.

[0150] The first enclosing structure 411b and the second enclosing structure 412b can be formed in a manner of standing up relative to the partition 40, specifically, relative to the first body part 411 and the second body part 412, and the standing height can be appropriately set according to the situation as long as it can block the condensed water. The first enclosing structure 411b and the second enclosing structure 412b can be formed on the first body part 411 and the second body part 412 by welding, threaded connection or one-piece manufacturing, etc. The formation of the first enclosing structure 411b and the second enclosing structure 412b on the first body part 411 and the second body part 412 is to be able to be arranged according to the layout needs of the wires and pipelines.

[0151] ​The first barrier structure 411b and the second barrier structure 412b can block the condensed water and prevent the condensed water from entering the first chamber 121 through the first through hole 411a and the second through hole 412a, thereby reducing the risk of short circuit of the busbar assembly 20.

[0152] In some embodiments, the energy storage device further comprises a hatch 50 connected to the box 10 and configured to at least close or open the electrical cabin 12 relative to the outside.

[0153] Optionally, the hatch 50 can be an independent hatch for closing the electrical cabin 12, or a shared hatch for closing the electrical cabin 12 and other cabins.

[0154] Since the hatch 50 can at least close or open the electrical cabin 12 relative to the outside, it is beneficial to protect the electrical components and the like in the electrical cabin 12. Moreover, when operating the electrical control assembly such as the distribution switch, maintaining the busbar assembly, or performing other operations in the electrical cabin 12, the hatch 50 can be opened or closed only to the electrical cabin 12, reducing the interference in other spaces such as the battery cabin 11.

[0155] In some embodiments, as shown in Figure 1 The first chamber 121 has a first chamber wall 121a closing a part of the hatch of the electrical cabin 12, the hatch 50 closes the rest of the hatch of the electrical cabin 12, and the partition 40 is connected to a first end 121b of the first chamber wall 121a close to the hatch 50 in the state that the hatch 50 closes the hatch of the electrical cabin 12.

[0156] As shown in Figure 1 The lower part of the hatch of the electrical cabin 12 is surrounded by the first chamber wall 121a. The first chamber wall 121a can be a part of the box wall on the outside of the box 10. Optionally, a reinforcing member (such as a door frame member or a door sill) can be added to the part of the first chamber wall 121a close to the door of the second chamber 122. The rest of the hatch of the electrical cabin 12 is closed by the hatch 50. Optionally, the size of the hatch 50 can be arbitrarily set as long as it can close the rest of the hatch of the electrical cabin 12. In a specific embodiment, the hatch 50 is formed to close the door of the second chamber 122, and the hatch 50 and the first chamber wall 121a together close the hatch of the electrical cabin 12.

[0157] Thus, it is beneficial to miniaturize the hatch 50, reduce the weight of the hatch 50, facilitate the operation of opening and closing the hatch 50, and also help reduce the overall weight of the energy storage device.

[0158] In some embodiments, as shown in Figure 1As shown, the door body of the hatch 50 towards the second chamber 122 in the state of closing the hatch is provided with the general control box 61, and the partition 40 comprises a baffle plate, which is configured as a bent plate comprising a first bent section 421, a second bent section 422 and a third bent section 423 connected in sequence, the third bent section 423 is connected to the first end portion 121b, in the state of closing the hatch by the hatch 50, in the case of projecting into the same projection plane in the direction perpendicular to the third bent section 423, the projection of the general control box 61 partially overlaps the projection of the third bent section 423, and the general control box is close to or abuts against the second bent section.

[0159] The door body of the hatch 50 towards the inner side of the electrical cabin 12 is provided with the general control box 61, and in the case of closing the electrical cabin 12 by the hatch 50, the general control box 61 is at least partially located in the second chamber 122.

[0160] The bent plate is formed to provide a avoiding space above the third bent section 423, which can at least avoid the lower part of the general control box 61. Specifically, the bent plate is formed to, in the state of closing the hatch by the hatch 50, in the case of projecting into the same projection plane in the direction perpendicular to the third bent section 423, the projection of the general control box 61 partially overlaps the projection of the third bent section 423. Here, the partial overlap includes that the projection of the general control box 61 does not exceed the projection of the third bent section 423 along the depth direction (for example, the second direction Y) of the electrical cabin 12. And the lower part of the general control box 61 is close to or abuts against the second bent section 422, specifically, abuts against the surface of the second bent section 422 towards the side of the hatch 50. That is, part of the general control box 61 is located in the sunken space formed by the second bent section 422 and the third bent section 423.

[0161] Therefore, by arranging the general control box 61 on the hatch 50, the space in the second chamber 122 and the installation position in the second chamber can be fully utilized; by configuring the baffle plate as a bent plate and providing an avoiding space for the general control box 61, the compactness of the layout of the components in the second chamber 122 can be improved.
