[0076] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0077] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0078] Since the energy people need is highly temporal and spatial, in order to rationally utilize energy and improve energy utilization, it is necessary to use a medium or device to store one form of energy in the same way or convert it into another form of energy, and then release it in a specific form of energy based on future application needs.

[0079] The current green energy mainly includes solar energy, wind energy, hydropower, etc. However, solar energy and wind energy generally have problems of strong intermittency and large volatility, which will cause unstable voltage of the green power grid (not enough electricity during peak hours and too much electricity during low hours). Unstable voltage will cause damage to electricity. Therefore, it may cause the problem of "wind and solar power abandonment" due to insufficient electricity demand or insufficient grid acceptance capacity.

[0080] To solve the problem of insufficient electricity demand or insufficient grid acceptance capacity, we must rely on energy storage devices. That is, the energy storage device converts electrical energy into other forms of energy through physical or chemical means and stores it, and then converts the energy stored in the energy storage device into electrical energy when needed. In simple terms, the energy storage device is similar to a large "power bank", which stores electrical energy when there is sufficient light energy and wind energy, and releases the stored electrical energy when needed.

[0081] At present, energy storage (i.e. energy storage) has a wide range of application scenarios, including power generation side energy storage, grid side energy storage, renewable energy grid-connected energy storage and user side energy storage. The corresponding types of energy storage devices include:

[0082] (1) Large energy storage containers used in grid-side energy storage scenarios can serve as high-quality active and reactive power regulation power sources in the grid, achieve load matching of electric energy in time and space, enhance the ability to absorb renewable energy, and are of great significance in grid system backup, relieving peak load power supply pressure, and peak and frequency regulation;

[0083] (2) The main operating mode of small and medium-sized energy storage cabinets used in industrial and commercial energy storage scenarios (banks, shopping malls, etc.) on the user side and small household energy storage boxes used in home energy storage scenarios on the user side is "peak shaving and valley filling". Since there is a large price difference in electricity charges at peak and valley locations according to electricity demand, after users have energy storage equipment, in order to reduce costs, they usually charge the energy storage cabinets / boxes during the low electricity price period; during the peak electricity price period, the electricity in the energy storage equipment is discharged for use to achieve the purpose of saving electricity bills. In addition, in remote areas and areas prone to natural disasters such as earthquakes and hurricanes, the existence of household energy storage devices is equivalent to users providing themselves and the power grid with backup power, eliminating the inconvenience caused by frequent power outages due to disasters or other reasons.

[0084] Take the household energy storage scenario in user-side energy storage as an example to illustrate. Figure 1 A household energy storage system is shown, which includes an energy storage device 1 and an electric energy conversion device 2 (such as a photovoltaic panel), and a user load 3 (such as a street lamp, household appliances, etc.). The energy storage device 1 is a small energy storage box that can be mounted on an outdoor wall by wall hanging. Specifically, the electric energy conversion device 2 can convert solar energy into electric energy during the period of low electricity prices, and store it through the energy storage device 1, and then supply the user load 3 for use during the peak electricity price, or supply the user load 3 for use when the power grid is out of power / power outage.

[0085] In combination with the above-mentioned situation of storing energy by physical or electrochemical means, taking electrochemical energy storage as an example, the energy storage device 1 includes at least one group of chemical batteries, using the chemical elements in the chemical batteries as energy storage media, so as to realize the charging and discharging process through the chemical reaction or change of the energy storage medium. In simple terms, the electric energy generated by light energy and wind energy is stored in at least one group of chemical batteries through the chemical reaction or change of the energy storage medium, and when the use of external electric energy reaches a peak, the electric energy stored in at least one group of chemical batteries is released for use through the chemical reaction or change of the energy storage medium, or transferred to a place where electric energy is scarce for use.

[0086] The embodiment of the present application provides an energy storage device 1, which may be, but is not limited to, an energy storage cabinet or energy storage box including a single cell. The single cell may be a lithium ion battery, a lithium sulfur battery, a sodium lithium ion battery, a sodium ion battery, a magnesium ion battery, etc. The single cell may be cylindrical, flat, rectangular, etc., and the embodiment of the present application does not limit this.

[0087] Next, the energy storage device 1 is described in detail by taking the energy storage cabinet as an example.

[0088] like Figure 2 As shown, the energy storage device 1 of the embodiment of the present application includes an energy storage cabinet 10, and the energy storage cabinet 10 has a battery compartment 10a and an electrical compartment 10b inside. The energy storage device 1 may also include multiple battery packs, a liquid cooling unit, a high-voltage box, etc. The battery compartment 10a is used to accommodate multiple battery packs, and the electrical compartment 10b is used to accommodate a liquid cooling unit, a high-voltage box, etc.

[0089] The energy storage cabinet 10 of the embodiment of the present application may be in the shape of a cuboid. For the convenience of explanation, the height direction of the energy storage cabinet 10 is defined as the first direction D1, the length direction of the energy storage cabinet 10 is defined as the second direction D2, and the width direction of the energy storage cabinet 10 is defined as the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0090] The battery compartment 10a and the electrical compartment 10b are arranged along the second direction D2.

[0091] like Figure 3 As shown, the energy storage cabinet 10 of the embodiment of the present application includes a main frame 10c, two side panels 62, a rear cover plate 63, a top plate 64, and a bottom plate 65. The main frame 10c is a rectangular frame structure as a whole, the two side panels 62 are respectively connected to the two sides of the second direction D2 of the main frame 10c, the top plate 64 and the bottom plate 65 are respectively connected to the two sides of the first direction D1 of the main frame 10c, and the rear cover plate 63 is connected to one side of the third direction D3 of the main frame 10c.

[0092] The energy storage cabinet 10 further includes a first partition 66 , which is disposed in the electrical compartment 10 b to separate the electrical compartment 10 b into two sub-compartments.

[0093] Continue reading Figure 3 The top plate 64 may include an outer top plate 64a and two inner top plates 64b, the two inner top plates 64b are connected to the top of the main frame 10c and arranged along the second direction D2. One of the inner top plates 64b is larger in size and corresponds to the battery compartment 10a, and the other inner top plate 64b is smaller in size and corresponds to the electrical compartment 10b. The outer top plate 64a is connected to the main frame 10c and covers the two inner top plates 64b.

[0094] Among them, a heat-insulating layer may be filled between the outer top plate 64a and the inner top plate 64b. The heat-insulating layer may be heat-insulating cotton, but is not limited thereto.

[0095] The bottom plate 65 includes an outer bottom plate 65a and two inner bottom plates 65b. The two inner bottom plates 65b are connected to the bottom of the main frame 10c and arranged along the second direction D2. One of the inner bottom plates 65b is larger in size and corresponds to the battery compartment 10a, and the other inner bottom plate 65b is smaller in size and corresponds to the electrical compartment 10b. The outer bottom plate 65a is connected to the main frame 10c and covers the two inner bottom plates 65b.

[0096] Among them, a heat-insulating layer may be filled between the outer bottom plate 65a and the inner bottom plate 65b. The heat-insulating layer may be heat-insulating cotton, but is not limited thereto.

[0097] The energy storage cabinet 10 further includes a second partition 67, which is disposed in the main frame 10c to separate the space in the main frame 10c into the battery compartment 10a and the electrical compartment 10b. The number of the second partitions 67 may be one or more. When the number of the second partitions 67 is multiple, the multiple second partitions 67 are arranged along the third direction D3. Moreover, the sizes of the multiple second partitions 67 may be the same or different.

[0098] like Figure 4 and Figure 5 As shown, the main frame 10c includes two frame structures 20 and a longitudinal beam 30, the two frame structures 20 are arranged opposite to each other in the height direction (first direction D1) of the energy storage cabinet 10, and the longitudinal beam 30 is connected between the two frame structures 20. Each frame structure 20 includes at least two adapters 100 and at least two side beams 200, each adapter 100 includes three plug-in structures 120a with different extension directions; two adjacent side beams 200 are respectively plugged into two different plug-in structures 120a of the same adapter 100 to form a ring structure; wherein, the positions of the adapters 100 of the two frame structures 20 correspond in the height direction of the energy storage cabinet 10, and the remaining plug-in structures 120a in the corresponding two adapters 100 are respectively plugged into the two ends of the length direction of the same longitudinal beam 30.

[0099] In the embodiment of the present application, the energy storage cabinet 10 includes two relatively arranged frame structures 20, and at least two adapters 100 and at least two side beams 200 are sequentially plugged into each frame structure 20 to form a ring structure. The corresponding adapters 100 in the two frame structures 20 are plugged into the two ends of the same longitudinal beam 30 in the length direction, so that the energy storage cabinet 10 is assembled as a whole using a splicing structure. The energy storage cabinet 10 can be disassembled into separate parts such as the side beams 200, the adapters 100, and the longitudinal beams 30. When encountering a complex and changeable assembly environment, it is convenient to disassemble and assemble the energy storage cabinet 10, thereby improving the disassembly and assembly efficiency; and the volume of the disassembled side beams 200, the adapters 100, the longitudinal beams 30 and other parts is significantly reduced compared to the energy storage cabinet 10, thereby effectively reducing the transportation cost.

[0100] It is understandable that the number of adapters 100 and side beams 200 included in each frame structure 20 may be two, three, four or other numbers, and the present application does not specifically limit this.

[0101] In one embodiment, each frame structure 20 may be a polygon, such as a rectangle, a pentagon, a hexagon, etc.

[0102] In the embodiment of the present application, each frame structure 20 is rectangular, and there are four adapters 100, four side beams 200, and four longitudinal beams 30. The four adapters 100 and the four side beams 200 are plugged in sequence to form a rectangular ring structure; and the two ends of each longitudinal beam 30 in the length direction are respectively plugged into two corresponding adapters 100 along the first direction D1.

[0103] It should be noted that, for the embodiment in which the frame structure 20 is rectangular, the number of the adapters 100 and the number of the side beams 200 may both be two, and the shape of the side beam 200 is L-shaped.

[0104] Next, each frame structure 20 is a rectangle and includes four adapters 100 and four side beams 200. The adapters 100 are respectively plugged into two adjacent side beams 200 and longitudinal beams 30. In order to simplify the diagram, Figure 5 FIG. 1 is an exploded schematic diagram showing only one corner of the energy storage cabinet 10. The plug-in structures of the remaining seven corners of the energy storage cabinet 10 will not be described again.

[0105] like Figure 5 As shown, each adapter 100 further includes a base 110, which has three non-coplanar outer surfaces 111, and each outer surface 111 is provided with a plug structure 120a. Two outer surfaces 111 of each base 110 are respectively in contact with the end surfaces of the two adjacent side beams 200 in the length direction, and the remaining outer surfaces 111 are in contact with the end surfaces of the longitudinal beam 30 in the length direction.

[0106] In the embodiment of the present application, not only are the three plug-in structures 120a of the adapter 100 respectively plugged into two adjacent side beams 200 and one longitudinal beam 30, but the three outer surfaces 111 of the adapter 100 are also respectively abutted against two adjacent side beams 200 and the longitudinal beam 30, thereby improving the overall structural strength of the frame structure 20.

[0107] In one embodiment, the extension directions of the three plug-in structures 120a are respectively parallel to the first direction D1, the second direction D2 and the third direction D3, that is, the extension directions of the three plug-in structures 120a are perpendicular to each other. Among them, the plug-in structure 120a parallel to the first direction D1 is plugged into the longitudinal beam 30, and the two plug-in structures 120a respectively parallel to the second direction D2 and the third direction D3 are plugged into two adjacent side beams 200.

[0108] like Figure 5 As shown, the energy storage cabinet 10 further includes a second fastener 310 ; two of the plug-in structures 120 a of each adapter 100 and the side beam 200 , and the remaining plug-in structures 120 a and the longitudinal beam 30 are detachably fastened together by at least one second fastener 310 .

[0109] In the embodiment of the present application, on the one hand, the overall strength of the frame structure 20 is enhanced under the action of the fastening connection of the second fastener 310; on the other hand, the second fastener 310 is connected in a detachable manner, which facilitates the disassembly and assembly of the frame structure 20, thereby realizing the disassembly and assembly of the energy storage cabinet 10.

[0110] It is understandable that the second fastener 310 can be a bolt. A through hole can be provided on the plug-in structure 120a, and threaded holes are provided at positions corresponding to the through holes on the side beam 200 and the longitudinal beam 30, and the bolts pass through the through holes and are screwed into the threaded holes to fasten the plug-in structure 120a to the side beam 200 and the plug-in structure 120a to the longitudinal beam 30.

[0111] Each plug-in structure 120a includes at least one plug-in portion 120; the side beam 200 has at least one first outer side surface 202, and the first outer side surface 202 is provided with a first slot 210, and the first slot 210 passes through the two end surfaces of the side beam 200 along the length direction of the side beam 200; at least one plug-in portion 120 is correspondingly plugged into at least one first slot 210.

[0112] In the embodiment of the present application, the first slot 210 is formed on the first outer side 202 of the side beam 200, so that the outer side of the side beam 200 can form multiple first slots 210, so that the plug-in structure 120a can include multiple plug-in parts 120, and the multiple plug-in parts 120 are plugged into the multiple first slots 210. The plug-in cooperation of the multiple plug-in parts 120 and the multiple first slots 210 improves the connection reliability between the adapter 100 and the side beam 200. In addition, the prior art has a mature profile (standard part), and the outer side of the profile has a first slot 210, so that the energy storage cabinet 10 of the embodiment of the present application can adopt the side beam 200 as a standard part, saving the mold opening cost.

[0113] Of course, in other embodiments, the first slot 210 may also be formed on the end surface of the side beam 200 .

[0114] In one embodiment, the side beam 200 has two first outer side surfaces 202 , and the two first outer side surfaces 202 are adjacent and perpendicular to each other. Correspondingly, the plug-in structure 120 a includes two plug-in portions 120 .

[0115] Each plug-in portion 120 has at least one through hole, and the bottom of the first slot 210 has at least one threaded hole corresponding to the through hole. At least one second fastener 310 passes through the at least one through hole and is screwed into the at least one threaded hole.

[0116] like Figure 5 As shown, along the width direction of the first slot 210 , the width of the opening of the first slot 210 is smaller than the maximum width of the corresponding plug-in portion 120 .

[0117] In the embodiment of the present application, along the depth direction of the first slot 210 , the plug-in portion 120 is limited in the first slot 210 , so that the plug-in fit between the plug-in portion 120 and the first slot 210 is more secure.

[0118] It is understandable that, in order to achieve the purpose of limiting the insertion portion 120 in the first slot 210 along the depth direction of the first slot 210, the cross-sectional shape of the first slot 210 can be designed to be a dovetail shape, and the cross-sectional shape of the insertion portion 120 is adapted thereto. During assembly, the insertion portion 120 is inserted into the first slot 210 from the end face of the side beam 200 until the outer surface 111 of the base 110 abuts against the end face of the side beam 200.

[0119] Of course, the cross-sectional shape of the first slot 210 is not limited to the dovetail shape. In other embodiments, any shape is acceptable as long as the opening width of the first slot 210 is smaller than the maximum width of the plug-in portion 120 and the plug-in portion 120 can be limited in the first slot 210 .

[0120] like Figure 5As shown, the side beam 200 also has a second outer side surface 203 different from the first outer side surface 202, and the second outer side surface 203 is provided with a second slot 220; each frame structure 20 also includes a first reinforcement 410 and a first fastener 320; the adjacent second outer side surfaces 203 of two adjacent side beams 200 are respectively fitted with a first reinforcement 410, and the first reinforcement 410 and the side beam 200 are fastened and connected by at least one first fastener 320; the first reinforcement 410 includes two first protrusions 411, and the two first protrusions 411 of a first reinforcement 410 are respectively inserted into the adjacent second slots 220 in the two adjacent side beams 200.

[0121] In the embodiment of the present application, two adjacent side beams 200 are further connected via a first reinforcement member 410 . By providing the first reinforcement member 410 and the first fastener 320 , the connection strength between the two adjacent side beams 200 can be further improved.

[0122] In one embodiment, along the width direction of the second slot 220 , the width of the opening of the second slot 220 is smaller than the maximum width of the corresponding first protrusion 411 .

[0123] In the embodiment of the present application, along the depth direction of the second slot 220 , the first protrusion 411 is limited in the second slot 220 , so that the plug-in fit between the first protrusion 411 and the second slot 220 is more secure.

[0124] The structure of the first protrusion 411 being limited in the second slot 220 may refer to the structure of the plug-in portion 120 and the first slot 210 , and will not be described in detail herein.

[0125] Please continue reading Figure 5 The longitudinal beam 30 has at least one fourth outer side surface 31, and the fourth outer side surface 31 is provided with a fourth slot 32, and the fourth slot 32 penetrates the two end surfaces of the longitudinal beam 30 along the length direction of the longitudinal beam 30; the plug-in structure 120a plugged with the longitudinal beam 30 has at least one plug-in part 120, and at least one plug-in part 120 is correspondingly plugged into at least one fourth slot 32.

[0126] In the embodiment of the present application, the fourth slot 32 is formed on the fourth outer side surface 31 of the longitudinal beam 30, so that the outer side surface of the longitudinal beam 30 can form multiple fourth slots 32, so that the plug-in structure 120a can include multiple plug-in parts 120, and the multiple plug-in parts 120 are plugged into the multiple fourth slots 32. The plug-in cooperation of the multiple plug-in parts 120 and the multiple fourth slots 32 improves the connection reliability between the adapter 100 and the longitudinal beam 30. In addition, the longitudinal beam 30 can use standard parts, saving mold opening costs.

[0127] In one embodiment, the longitudinal beam 30 has two fourth outer side surfaces 31 , and the two fourth outer side surfaces 31 are adjacent and perpendicular to each other. Correspondingly, the plug-in structure 120 a plugged with the longitudinal beam 30 has two plug-in parts 120 .

[0128] The side beam 200 further has a third outer side surface 204 different from the first outer side surface 202 and the second outer side surface 203, and the third outer side surface 204 is provided with a third slot 230; the third slot 230 penetrates the two end surfaces of the side beam 200 along the length direction of the side beam 200. The longitudinal beam 30 further has two fifth outer side surfaces 33 different from the fourth outer side surface 31, and the fifth outer side surface 33 is provided with a fifth slot 34; the fifth slot 34 penetrates the two end surfaces of the longitudinal beam 30 along the length direction of the longitudinal beam 30.

[0129] Each frame structure 20 also includes a second reinforcement 420 and a third fastener 330. Two adjacent side beams 200 are connected to the longitudinal beam 30 through two second reinforcements 420, and the second reinforcement 420 and the longitudinal beam 30, as well as the second reinforcement 420 and the side beam 200 are fastened and connected through at least one third fastener 330. The second reinforcement 420 includes two second protrusions 421, and the two second protrusions 421 of the second reinforcement 420 are respectively inserted into the fifth slot 34 and the third slot 230.

[0130] In the embodiment of the present application, the longitudinal beam 30 is connected to each side beam 200 via the second reinforcement 420 and the third fastener 330 , so that the energy storage cabinet 10 is more secure at the corner where the adapter 100 is located, thereby ensuring the overall structural strength of the energy storage cabinet 10 .

[0131] Along the width direction of the third slot 230, the width of the opening of the third slot 230 is smaller than the maximum width of the corresponding second protrusion 421; and / or, along the width direction of the fourth slot 32, the width of the opening of the fourth slot 32 is smaller than the maximum width of the corresponding plug-in portion 120; and / or, along the width direction of the fifth slot 34, the width of the opening of the fifth slot 34 is smaller than the maximum width of the corresponding second protrusion 421.

[0132] In the embodiment of the present application, the second protrusion 421 is limited to the third slot 230, so that the plug-in fit between the second protrusion 421 and the third slot 230 is more secure; the plug-in part 120 is limited to the fourth slot 32, so that the plug-in fit between the plug-in part 120 and the fourth slot 32 is more secure; the second protrusion 421 is limited to the fifth slot 34, so that the plug-in fit between the second protrusion 421 and the fifth slot 34 is more secure. Therefore, the overall structural strength of the energy storage cabinet 10 is further improved.

[0133] It can be understood that the limiting cooperation between the second protrusion 421 and the third slot 230, the limiting cooperation between the plug-in part 120 and the fourth slot 32, and the limiting cooperation between the second protrusion 421 and the fifth slot 34 can refer to the limiting cooperation structure between the plug-in part 120 and the first slot 210, and will not be repeated here.

[0134] In one embodiment, the first reinforcement 410 and the second reinforcement 420 have the same structure and size. In this way, the versatility of the reinforcement is improved, so that the first reinforcement 410 between two adjacent side beams 200 and the second reinforcement 420 between the side beam 200 and the longitudinal beam 30 can be shared, which not only avoids the waste of mold opening costs due to the different structures of the two reinforcements, but also facilitates the operator to assemble the reinforcement.

[0135] like Figure 4 and Figure 6 As shown, a longitudinal beam 30 is provided between two side beams 200 corresponding to each other in the first direction D1 in the two frame structures 20, and both ends of the longitudinal beam 30 in the length direction are respectively fixedly connected to the remaining areas of the two side beams 200 except the ends. By providing the longitudinal beam 30 between the two side beams 200 corresponding to each other in the two frame structures 20, the overall structural strength of the main frame 10c can be improved, and the problem of weakening strength due to the excessive length of the side beams 200 can be avoided.

[0136] The longitudinal beam 30 and the side beam 200 may be connected by a second reinforcement member 420 .

[0137] In detail, the two second protrusions 421 of the second reinforcement member 420 are respectively inserted into the fifth slot 34 of the longitudinal beam 30 and the third slot 230 of the side beam 200. In addition, the second reinforcement member 420 is detachably fastened to the longitudinal beam 30 by at least one fastener, and the second reinforcement member 420 is detachably fastened to the side beam 200 by at least one fastener.

[0138] In the embodiment of the present application, the two frame structures 20 have four pairs of corresponding side beams 200 , and a longitudinal beam 30 is disposed between each pair of side beams 200 .

[0139] There may be one or more longitudinal beams 30 between two corresponding side beams 200. When there are multiple longitudinal beams 30 between two corresponding side beams 200, the multiple longitudinal beams 30 are parallel to the first direction D1.

[0140] It is worth mentioning that in the embodiment of the present application, in the third direction D3, the boundary line between the battery compartment 10a and the electrical compartment 10b corresponds to two longitudinal beams 30. In other words, the two longitudinal beams 30 are used to install the second partition plate 67.

[0141] like Figure 4 and Figure 7As shown, each frame structure 20 also includes a partition beam 700, which can be connected between any two side beams 200 in the frame structure 20 to divide the area enclosed by at least two side beams 200 and at least two adapters 100 into two sub-areas, one of which is provided with one inner top plate 64b or inner bottom plate 65b, and the other sub-area is provided with another inner top plate 64b or inner bottom plate 65b.

[0142] In the embodiment of the present application, a partition beam 700 is connected between two side beams 200 disposed opposite to each other along the third direction D3 in the frame structure 20. In addition, the partition beam 700 corresponds to the boundary between the battery compartment 10a and the electrical compartment 10b, that is, the partition beam 700 is used to install the second partition plate 67.

[0143] The partition beam 700 can be connected to the side beam 200 and the longitudinal beam 30 by reinforcements and fasteners. In detail, five reinforcements are provided at the connection intersection of the side beam 200, the longitudinal beam 30 and the partition beam 700. Among them, the partition beam 700 is connected to the side beam 200 by two reinforcements, the partition beam 700 is connected to the longitudinal beam 30 by one reinforcement, and the longitudinal beam 30 is connected to the side beam 200 by two reinforcements. The reinforcement can be the first reinforcement 410 or the second reinforcement 420 mentioned above, and the specific connection structure can refer to the way in which the side beam 200 and the longitudinal beam 30 are connected by the first reinforcement 410 and the second reinforcement 420, which will not be repeated here.

[0144] like Figure 4 As shown, in the first direction D1, a longitudinal beam 30 is further provided between the two corresponding partition beams 700, and the longitudinal beam 30 is used to install the second partition plate 67. The longitudinal beam 30 divides the area surrounded by the two partition beams 700 into two sub-areas, and two second partition plates 67 are respectively provided in the two sub-areas.

[0145] The connection method of the longitudinal beam 30 and the partition beam 700 can refer to the connection method of the longitudinal beam 30 and the side beam 200, which will not be repeated here.

[0146] like Figure 8 As shown, the portion of the second slot 220 of the side beam 200 where the first protrusion 411 is not provided is filled with two filling bodies 500, the two filling bodies 500 are arranged opposite to each other along the width direction of the second slot 220, and there is a gap G between the two filling bodies 500; the energy storage cabinet 10 also includes a splint 600, the edge of the splint 600 is inserted into the gap G, and is clamped between the two filling bodies 500.

[0147] In the embodiment of the present application, the clamping plate 600 is sandwiched between the two filling bodies 500 filled in the second slot 220, ensuring the sealing of the frame structure 20 and preventing external dust or moisture from entering the energy storage cabinet 10 and affecting the reliable operation of the energy storage device 1.

[0148] It should be noted that when the frame structure 20 includes a partition beam 700, the clamping plate 600 can be two inner top plates 64b or inner bottom plates 65b. For the convenience of explanation, the clamping plate 600 is taken as two inner top plates 64b as an example. The partition beam 700 has two slots arranged opposite to each other along the second direction D2, and the two slots can be respectively provided for two reinforcing members to be plugged in. In addition, the two slots of the partition beam 700 are also filled with two filling bodies 500, respectively, so that the edge of one of the inner top plates 64b can be inserted between the two filling bodies 500 in one of the slots, and the edge of the other inner top plate 64b can be inserted between the two filling bodies 500 in the other slot.

[0149] Of course, it is understandable that the sealing connection method between the second partition plate 67 and the longitudinal beam 30 and the partition beam 700 can also adopt the sealing connection method between the inner top plate 64b and the side beam 200 and the partition beam 700, which will not be repeated here.

[0150] The edge of the clamping plate 600 is provided with an escape opening 610 for evading the first reinforcement member 410. In the embodiment of the present application, the four corners of the inner top plate 64b are provided with an escape opening 610 to evade the four reinforcement members.

[0151] like Figure 4 and Fig. 9 As shown, the battery compartment 10a and the electrical compartment 10b are further provided with a support member 40. The support member 40 in the battery compartment 10a is used to support the battery pack, and the support member 40 in the electrical compartment 10b is used to support the first partition 66.

[0152] The battery compartment 10a is surrounded by six longitudinal beams 30, wherein the four longitudinal beams 30 not connected to the rear cover plate 63 are provided with a plurality of support members 40, and the plurality of support members 40 on each longitudinal beam 30 are arranged along the first direction D1. In the first direction D1, a receiving position for receiving the battery pack is formed between adjacent support members 40.

[0153] The electrical compartment 10 b is surrounded by six longitudinal beams 30 , each longitudinal beam 30 is provided with a support member 40 , and these support members 40 are in the same horizontal plane and are used to support the first partition plate 66 .

[0154] The support member 40 may include a third protrusion 41 , which is inserted into a slot of the longitudinal beam 30 corresponding to the support member 40 , and the support member 40 and the longitudinal beam 30 are detachably fastened together by at least one fourth fastener 340 .

[0155] Please continue reading Figure 4 and Fig. 9, a positioning member 50 is also provided in the battery compartment 10a. The battery compartment 10a is surrounded by six longitudinal beams 30, wherein two longitudinal beams 30 connected to the rear cover plate 63 are provided with a plurality of positioning members 50. The plurality of positioning members 50 on each longitudinal beam 30 are arranged along the first direction D1. The positioning members 50 on the two longitudinal beams 30 are arranged opposite to each other in the second direction D2. The positioning members 50 are installed on the longitudinal beams 30 to stop the battery pack so as to remind the assembler that the battery pack has been plugged in place.

[0156] In one embodiment, the positioning member 50 has the same structure and size as the support member 40. Since the positioning member 50 and the support member 40 have the same structure and size, the versatility of the parts is improved, so that the positioning member 50 and the support member 40 can be shared, which not only avoids the waste of mold opening costs due to the different structures of the positioning member 50 and the support member 40, but also facilitates the operator to install the positioning member 50 and the support member 40.
