Description

Technical Field

[0001] The utility model relates to the field of energy storage, in particular to a battery energy storage cabinet. Background Art

[0002] In the field of battery energy storage, the battery pack is its core component, and its performance and reliability directly affect the performance and reliability of the entire battery energy storage system.

[0003] See also Figure 1 As shown in the schematic diagram of the battery pack structure, a housing bottom plate 111 and a plurality of housing side walls 112 form a housing 110, and a cell module is accommodated in the housing 110 to form a battery pack 100. The housing bottom plate 111 is usually a cold plate, such as a liquid cooling plate.

[0004] In actual implementation, multiple battery packs 100 are placed in a cabinet 200 to form a battery energy storage cabinet for customer use. Figure 2 As shown in the exploded diagram of the battery energy storage cabinet, multiple sets of slides 210 are symmetrically and spaced apart on the opposite first cabinet side walls 201 and second cabinet side walls 202. A battery pack 100 is placed on a corresponding set of symmetrical slides 210, and then the battery pack 100 is fixed to the slides 210 using fixing members (such as screws) to fix the battery pack 100 in the cabinet 200.

[0005] As can be seen from the above description, the battery pack 100 is secured within the cabinet 200 only by fasteners to the slides 210. Firstly, the limited number of fastening points results in a loose fixation of the battery pack 100 within the cabinet 200. Secondly, the portion of the housing bottom plate 111 located between the two slides 210 is suspended in the air, lacking any stress points. This makes the housing bottom plate 111 of the battery pack 100 susceptible to deformation, particularly in the middle portion between the two slides 210. This in turn leads to inconsistent performance of the battery cells within, such as inconsistent temperatures. This can even lead to overheating of the cells in the middle portion, preventing them from properly providing power, impacting the performance and reliability of the entire battery energy storage cabinet.

[0006] Therefore, the industry is in urgent need of a battery energy storage cabinet that can not only reliably fix the battery pack but also improve the performance and reliability of the battery pack. Utility Model Content

[0028] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] In one embodiment of the present invention, a battery energy storage cabinet is provided. Figure 3 The schematic diagram of the battery energy storage cabinet according to one embodiment of the present application is shown. Figure 4 The exploded diagram of the battery energy storage cabinet according to one embodiment of the present application is shown. Figure 5 The schematic diagram of a battery pack including a first structural member used in conjunction with the battery pack according to an embodiment of the present application is shown. Figure 6 The first structural member schematic diagram of an embodiment of the present application is shown, and the battery energy storage cabinet includes:

[0030] The cabinet 200 includes a first cabinet side wall 201 and a second cabinet side wall 202 opposite to the first cabinet side wall 201;

[0031] Multiple groups of slides 210 , each group of slides 210 includes a first sub-slide 211 and a second sub-slide 212 , the first sub-slide 211 is disposed on the first cabinet side wall 201 , and the second sub-slide 212 is disposed on the second cabinet side wall 202 ;

[0032] Multiple battery packs 100, each including a housing 110 formed by a housing bottom plate 111 and a plurality of housing side walls 112, and battery cells accommodated in the housing 110, wherein the housing bottom plate 111 of each battery pack 100 is placed on a set of slides 210;

[0033] Multiple first structural members 300, each first structural member 300 includes a crossbeam 310, the crossbeam 310 is located on the side of the shell bottom plate 111 of a battery pack 100 away from the battery pack 100, and extends from the first sub-slide 211 in a group of slides 210 to the second sub-slide 212, and a first structural member 300 is correspondingly fixed on a group of slides 210 and on the shell bottom plate 111 of a battery pack 100.

[0034] In actual implementation, after the battery pack 100 is placed on a set of slides 210, the first structural member 300 is assembled. As can be seen from the above description, one first structural member 300 is correspondingly fixed to a set of slides 210 and to the housing bottom plate 111 of one battery pack 100. This ensures that the battery pack 100 and the slides 210 are fixedly connected as a whole via the first structural member 300. This increases the number of fixing points for the battery pack 100, prevents the battery pack 100 from shaking during use of the battery energy storage cabinet, and improves the performance of the entire battery energy storage cabinet. Furthermore, the crossbeam 310 extends from the bottom of the battery pack 100, i.e., the side of the housing bottom plate 111 away from the battery pack 100, spanning the battery pack 100 and supporting the housing bottom plate 111. This increases the strength of the housing bottom plate 111, making it less likely to deform, thereby improving the performance of the entire battery energy storage cabinet.

[0035] For further information, see Figure 4 and Figure 5 The first sub-slide rail 211 and the second sub-slide rail 212 in each group of slide rails 210 are symmetrically arranged on the opposite first cabinet side wall 201 and second cabinet side wall 202 .

[0036] In actual implementation, the shell bottom plate 111 is also fixed to the slide 210 through a fixing member. The specific fixing method is not limited in this application, and any available fixing method in the industry is applicable to this application.

[0037] For further information, see Figure 5 and Figure 6 The first structural member 300 further includes: a bending portion 320 and a first pressing grip 330 .

[0038] like Figure 5 and Figure 6 As shown, the bent portion 320 and the crossbeam 310 form an L-shaped structure. Specifically, the bent portion 320 extends from one side of the crossbeam 310 toward the battery pack 100 and forms a certain angle with the crossbeam 310, such as 90 degrees.

[0039] like Figure 5 and Figure 6As shown, the first pressing grip 330 extends from the side of the bent portion 320 away from the crossbeam 310 toward the battery pack 100 and presses against the housing bottom plate 111. The bent portion 320 thus extends along the thickness of the housing bottom plate 111, with the first pressing grip 330 and the crossbeam 310 located on opposite sides of the housing bottom plate 111. By adjusting the length of the bent portion 320, the first pressing grip 330 and the crossbeam 310 are securely fastened to the housing bottom plate 111, creating opposing forces that increase the force-bearing surface area of ​​the battery pack 100. Furthermore, as described above, the first structural member 300 is also fixed to the slideway 210, which allows it to reliably limit the freedom of the battery pack 100, thereby improving the reliability of the battery energy storage cabinet.

[0040] like Figure 5 and Figure 6 As shown, a first fixing hole 321 is provided on the bent portion 320, and a second fixing hole 1111 is also provided in the thickness direction of the housing bottom plate 111. A fixing member 510 passes through the first fixing hole 321 and the second fixing hole 1111 to fix the first structural member 300 to the housing bottom plate 111. As can be seen from the above description of the first structural member 300, the bent portion 320 extends along the thickness direction of the housing bottom plate 111. Preferably, the bent portion 320 is parallel to the thickness direction of the housing bottom plate 111. In this way, the fixing member 510 can be passed through the first fixing hole 321 and the second fixing hole 1111 to fix the first structural member 300 to the housing bottom plate 111.

[0041] In actual implementation, Figure 5 and Figure 6 As shown, a plurality of spaced apart bending portions 320 may be provided, and whether or not a first fixing hole 321 is provided on each bending portion 320 and the number of the first fixing holes 321 may be selected according to the fixing requirements, such as Figure 5 and Figure 6 As shown in FIG, a first fixing hole 321 is provided on each bending portion 320. Similarly, whether to extend the first pressing catch 330 from each bending portion 320 is selected according to the needs, such as Figure 5 and Figure 6 As shown in FIG, a first pressing grip 330 extends from each bending portion 320 .

[0042] For further information, see Figure 5 and Figure 6 The crossbeam 310 includes a first end 311 and a second end 312. The first end 311 is located below and fixedly connected to the first sub-slide 211 in the set of slides 210, and the second end 312 is located below and fixedly connected to the second sub-slide 212 in the set of slides 210. In this way, the first structural member 300 is fixed to the set of slides 210.

[0043] In an actual implementation embodiment, as Figure 5 and Figure 6 As shown in FIG, the first sub-slide 211, the first end 311, the second sub-slide 212 and the second end 312 are provided with fixing holes. A fixing member 411 passes through the fixing hole on the first sub-slide 211 and the fixing hole 3111 on the first end 311, and a fixing member 412 passes through the fixing hole on the second sub-slide 212 and the fixing hole 3121 on the second end 312, thereby fixing the first structural member 300 on a set of slides 210. For more detailed description, please refer to Figure 7 shown Figure 5 In the enlarged schematic diagram of the area marked B, a fixing hole (not shown in the figure) is provided on the end of the first sub-slide 211, and a fixing hole 3111 is also provided at the corresponding position of the first end 311 of the first structural member 300. The first sub-slide 211 can be fixed to the first structural member 300 by a fixing member 411, such as by screws or nuts.

[0044] We know that the shell bottom plate 111 of the battery pack 100 is placed on a group of slides 210, and the crossbeam 310 of the first structural member 300 is located on the side of the shell bottom plate 111 of the battery pack 100 away from the battery pack 100. Then the first end 311 and the shell bottom plate 111 are separated by a first sub-slide 211, and the second end 312 and the shell bottom plate 111 are separated by a second sub-slide 212. Fixing holes are provided on the first sub-slide 211, the first end 311, the second sub-slide 212 and the second end 312. Then the fixing member passes through the fixing holes on the first sub-slide 211 and the first end 311 in the height direction of the battery pack 100, and the fixing member passes through the fixing holes on the second sub-slide 212 and the second end 312 in the height direction of the battery pack 100, so as to fix the first structural member 300 on a group of slides 210 and limit the freedom of the first structural member 300.

[0045] In actual implementation, the shell bottom plate 111 of the battery pack 100 is also fixed to the slide 210 by a fixing member, and the first structural member 300 is fixed to a set of slides 210 and the shell bottom plate 111 of the battery pack 100. In this way, the freedom of the battery pack 100 is limited, and the first structural member 300 supports the shell bottom plate 111, which not only increases the force points of the battery pack 100 in the battery energy storage cabinet and improves its fixation reliability, but also avoids deformation of the shell bottom plate 111 of the battery pack 100, thereby improving its reliability.

[0046] Furthermore, if Figure 5 and Figure 6As shown in , the portion of the crossbeam 310 located between the first end 311 and the second end 312 is attached to the housing bottom plate 111; the first sub-slide 211 is separated from the first end 311 and the housing bottom plate 111, and the second sub-slide 212 is separated from the second end 312 and the housing bottom plate 111. In other words, there is a height difference 313 between the first end 311 and the second end 312 relative to the portion of the crossbeam 310 located between the first end 311 and the second end 312. This height difference 313 can accommodate the thickness of the slide 210. In this way, the portion of the crossbeam 310 located between the first end 311 and the second end 312 can be attached to the housing bottom plate 111, thereby providing support for the housing bottom plate 111.

[0047] Furthermore, if Figure 5 and Figure 6 As shown in the figure, the first end portion 311 and the second end portion 312 are used to be fixed to the slide 210, and fixing holes need to be set thereon. For this purpose, the width of the first end portion 311 and the second end portion 312 can be designed to be larger than the width of the portion of the beam 310 located between the first end portion 311 and the second end portion 312, and no bending portion 320 is set at the first end portion 311 and the second end portion 312.

[0048] In actual application, a first window 203 (eg, a window 203 ) is formed between the first side wall 201 and the second side wall 202 of the cabinet 200. Figure 4 ) and a second window 204 (as shown Figure 9 (as shown), the battery pack 100 is pushed into the cabinet 200 through the first window 203 along a set of slides 210, or is placed on the set of slides 210 through the first window 203 using a mechanical device. The battery pack 100 is then secured to the slides 210 using fasteners, and the first structural member 300 is then secured to the housing bottom plate 111 of the battery pack 100 and the slides 210 through the first window 203. However, this may cause the end of the battery pack 100 located at the second window 204 to be free to move, for example, moving along the height or width of the battery pack 100.

[0049] To this end, in one embodiment of the present application, the battery energy storage cabinet further includes a plurality of second structural members 600. Figure 8 The schematic diagram of the battery energy storage cabinet according to one embodiment of the present application is shown. Figure 9 The exploded diagram of the battery energy storage cabinet according to one embodiment of the present application is shown. Figure 10 The schematic diagram of a battery pack including a second structural member used in conjunction with the battery pack according to an embodiment of the present application is shown. Figure 11The second structural member of an embodiment of the present application is shown in the schematic diagram. In actual implementation, a second structural member 600 and a first structural member 300 are respectively arranged at opposite ends of a battery pack 100, wherein the first structural member 300 is arranged at one end of the battery pack 100 located at the first window 203 of the cabinet 200, as described above. Figure 4 and Figure 5 The second structural member 600 is provided at one end of the second window 204 of the cabinet 200 of the battery pack 100, as described above. Figure 7 and Figure 9 .

[0050] Specifically, such as Figure 10 and Figure 11 As shown, each second structural member 600 includes a first surface 610 and a second surface 620 at a predetermined angle (e.g., 90°) to the first surface 610. The first surface 610 is located on the side of the housing bottom plate 111 away from the battery pack 100. The second surface 620 extends toward the battery pack 100 (or along the thickness of the housing bottom plate 111) and is secured to the housing bottom plate 111 and a set of slideways 210. The second structural member 600 similarly securely connects the slideways 210 and the battery pack 100 as a single unit. Thus, the first structural member 300 and the second structural member 600, respectively, define the freedom of the battery pack 100 at both ends of the battery pack 100, thereby preventing vibration and displacement of the battery pack 100 during use (e.g., transportation) of the battery energy storage cabinet, thereby improving the reliability of the battery energy storage cabinet.

[0051] For further information, see Figure 10 and Figure 11 The second surface 620 is provided with a third fixing hole 621, and the housing bottom plate 111 is provided with a fourth fixing hole 1112 in the thickness direction. A fixing member 710 passes through the third fixing hole 621 and the fourth fixing hole 1112 to fix the second structural member 600 to the housing bottom plate 111. The first sub-slide 211 is provided with a fifth fixing hole 2112, and the second sub-slide 212 is provided with a sixth fixing hole 2122. A fixing member passes through the third fixing hole 621 on the second surface 620 and the fifth fixing hole 2112 on the first sub-slide 211, and another fixing member passes through the third fixing hole 621 on the second surface 620 and the sixth fixing hole 2122 on the second sub-slide 212 to fix the second structural member 600 to the set of slides 210. Similar to the first structural member 300, the second structural member 600 is also fixed to the slide 210 and the housing bottom plate 111 of the battery pack 100.

[0052] For further information, see Figure 10 and Figure 11The first sub-slide 211 includes a first blocking portion 2111 formed at a certain angle (e.g., 90°) to the slide body, and the fifth fixing hole 2112 provided on the first sub-slide 211 is disposed on the first blocking portion 2111. The second sub-slide 212 includes a second blocking portion 2121 formed at a certain angle (e.g., 90°) to the slide body, and the sixth fixing hole 2122 provided on the second sub-slide 212 is disposed on the second blocking portion 2121. In practice, the first blocking portion 2111 and the second blocking portion 2121 are used to limit the battery pack 100 when it is placed on the slide 210.

[0053] For further information, see Figure 10 and Figure 11 The second structural member 600 further includes a second pressing grip 630. The second pressing grip 630 of the second structural member 600 extends from the second surface 620 toward the battery pack 100 and presses against the bottom plate 111 of the housing. Figure 10 and Figure 11 As shown, similar to the first structural member 300 , the second pressing grip 630 and the first surface 610 are located on two sides of the shell bottom plate 111 and fastened to the shell bottom plate 111 , and their functions are also the same and will not be repeated here.

[0054] The first pressing grip 330 and the second pressing grip 630 may include protrusions protruding toward the housing bottom plate 111 to press against the bottom plate. Of course, the pressing grips may also be other structures as long as they can press against the bottom plate.

[0055] In actual implementation, the first structural member 300 may be an integrally formed member, or a member in which various components are fixedly connected together, which is not limited in this application.

[0056] In actual implementation, the second structural member 600 may be an integrally formed member, or a member in which various components are fixedly connected together, which is not limited in this application.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
