For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] Refer to the following Figures 1 to 10 An energy storage cabinet according to some embodiments of the present application is described.

[0043] See also Figures 1 to 10 As shown, an embodiment of the present application provides an energy storage cabinet, comprising: a cabinet body, an immersion liquid-cooled battery pack 100, and a liquid cooling circulation system; wherein, there are multiple immersion liquid-cooled battery packs 100, and the multiple immersion liquid-cooled battery packs 100 are stacked together in sequence along the height direction of the cabinet body, and any immersion liquid-cooled battery pack 100 is connected to the liquid cooling circulation system;

[0044] Any immersion liquid-cooled battery pack 100 includes a battery pack box 1, and an upper reinforcing beam 11, a supporting member 12, a lower reinforcing beam 13 and a connecting member 14 arranged in the battery pack box 1. The upper reinforcing beam 11 is fixed to the inner side wall of the upper part of the battery pack box 1, and the supporting member 12 is detachably mounted on the upper reinforcing beam 11;

[0045] The lower reinforcing beam 13 is fixed on the inner bottom wall of the battery pack box 1 ; the connecting member 14 is disposed between the supporting member 12 and the lower reinforcing beam 13 , and the connecting member 14 is detachably connected to the supporting member 12 and the lower reinforcing beam 13 , respectively.

[0046] Based on the structure described above, it can be seen that in any immersion liquid-cooled battery pack 100 of the energy storage cabinet provided by the present application, the battery pack box 1 is connected as a whole through the design of the upper reinforcing beam 11, the lower reinforcing beam 13, the supporting member 12 and the connecting member 14 to form an overall network, thereby improving the rigidity of the battery pack box 1 and ensuring that the battery pack box 1 can withstand a certain liquid pressure. In addition, by designing the reinforcing beam, the weight and volume of the battery pack box 1 are effectively reduced compared with the cast iron casting type battery pack box 1, thereby improving the energy density of the immersion liquid-cooled battery pack 100, while also being of good quality. The appearance of the immersed liquid-cooled battery pack 100 is taken into consideration, and the mold opening cost is saved, that is, the cost of the battery pack case 1 is reduced. Moreover, according to the different rigidity requirements of the immersed liquid-cooled battery pack 100 at different heights, the number and position of the supporting members 12 and the connecting rods in the battery pack case 1 can be adjusted, and then the rigidity of the battery pack case 1 can be controlled, ensuring that each layer of the immersed liquid-cooled battery pack 100 in the energy storage system has appropriate rigidity to resist the strong effect of the cooling liquid, effectively reducing the cost and weight of the energy storage system, and realizing the controllable rigidity of the overall battery pack case 1 of the energy storage system.

[0047] In this embodiment, preferably, Figure 2 and Figure 3 As shown, the support member 12 and the upper reinforcing beam 11 are detachably connected via a first fastening member (the first fastening member is not shown in the figure).

[0048] According to the structure described above, the support member 12 is connected to the upper reinforcing beam 11 by a first fastening member such as a screw or a bolt, which is a detachable connection structure. Therefore, the number of support members 12 can be adjusted according to the stiffness requirements of the immersed liquid-cooled battery pack 100 with different layer heights, and the adaptability is wider. There is no need to design each layer of the immersed liquid-cooled battery pack 100 to have the same stiffness, resulting in material waste.

[0049] It should be noted that the connection method between the support member 12 and the upper reinforcing beam 11 is not limited to this. The support member 12 and the upper reinforcing beam 11 can also be connected by a snap connection such as a snap fit or an interference fit, which is selected according to actual needs.

[0050] In this embodiment, preferably, Figure 4 As shown, the connecting member 14 and the supporting member 12 are detachably connected via a second fastening member.

[0051] According to the structure described above, the connecting member 14 is connected to the supporting member 12 through the second fastening member, which is a detachable connecting structure. Therefore, the number of connecting members 14 can be adjusted according to the stiffness requirements of the immersion liquid-cooled battery pack 100 with different layer heights, and the adaptability is wider. There is no need to design each layer of the immersion liquid-cooled battery pack 100 to have the same stiffness, resulting in material waste.

[0052] In this embodiment, preferably, Figure 4 and Fig. 9 As shown, the top end of the connecting member 14 along its height direction is provided with a first protrusion 141, and the first protrusion 141 is provided with an external thread; the second fastening member is a nut 15, and the supporting member 12 is formed with a through hole, and is sleeved on the first protrusion 141 through the through hole and locked by the nut 15.

[0053] According to the structure described above, since the first protrusion 141 is designed at the top of the connecting member 14, a first installation step is formed on the periphery of the first protrusion 141 of the connecting member 14, and then when the supporting member 12 is sleeved on the outside of the first protrusion 141 through the through hole thereon, the supporting member 12 is just seated on the first installation step to play a supporting role, and then the nut 15 can be used to lock the connecting member 14 and the supporting member 12 together.

[0054] It should be noted that the connection method between the connecting member 14 and the supporting member 12 is not limited to this. The connecting member 14 and the supporting member 12 can also be connected by means of snap connection or interference fit, etc., which can be selected according to actual needs.

[0055] In this embodiment, preferably, Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown, the connecting member 14 is detachably connected to the lower reinforcing beam 13 via threads, which is a commonly used connection method with low processing and manufacturing costs and convenient installation and disassembly.

[0056] In this embodiment, preferably, Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown, the bottom end of the connecting member 14 along the height direction thereof is provided with a second protrusion 142 , and the second protrusion 142 is provided with an external thread, the lower reinforcing beam 13 is formed with a threaded hole, and the second protrusion 142 is threadedly connected to the threaded hole.

[0057] According to the structure described above, since the second protrusion 142 is designed at the bottom end of the connecting member 14, a second installation step is formed on the periphery of the second protrusion 142 of the connecting member 14, and then when the second protrusion 142 is screwed into the threaded hole of the lower reinforcing beam 13, the second installation step abuts against the upper surface of the lower reinforcing beam 13, thereby playing a limiting role.

[0058] In this embodiment, preferably, Figure 6 and Figure 7 As shown, the lower reinforcing beam 13 is connected to the inner bottom wall of the battery pack box 1 by welding.

[0059] According to the structure described above, it can be seen that the lower reinforcing beam 13 and the inner bottom wall of the battery pack box 1 are welded together, and the connection is stronger and more stable, which helps to improve the overall strength and rigidity.

[0060] It should be noted that the connection method between the lower reinforcing beam 13 and the inner bottom wall of the battery pack case 1 is not limited to the above-mentioned welding. The lower reinforcing beam 13 and the inner bottom wall of the battery pack case 1 can also be connected by bolts or clamping.

[0061] In this embodiment, preferably, Figure 6 and Figure 7 As shown, the upper reinforcing beam 11 is connected to the inner wall of the battery pack box 1 by welding.

[0062] According to the structure described above, it can be seen that the upper reinforcing beam 11 and the inner wall of the battery pack body 1 are welded together, and the connection is stronger and more stable, which helps to improve the overall strength and rigidity.

[0063] It should be noted that the connection method between the upper reinforcing beam 11 and the inner wall of the battery pack box 1 is not limited to the above-mentioned welding. The upper reinforcing beam 11 and the battery pack box 1 can also be connected by bolts or clamping.

[0064] In this embodiment, preferably, Figure 6 and Figure 7 As shown, there are multiple upper reinforcing beams 11 , which correspond one-to-one to and are connected to multiple side portions of the battery pack box 1 , wherein any two adjacent upper reinforcing beams 11 are connected.

[0065] According to the structure described above, it can be seen that reinforcing beams are arranged around the entire circumference of the battery pack case 1 and are connected together to improve the overall strength and rigidity of the battery pack case 1.

[0066] Further, preferably, any two adjacent upper reinforcing beams 11 may also be connected by welding. Of course, this is not limited to this, and they may also be connected by other means such as bolts or clamping.

[0067] In this embodiment, preferably, Figure 8 As shown, since the area of ​​the bottom wall of the battery pack case 1 is larger than the area of ​​the side wall, and the liquid pressure on the bottom wall is also greater than the pressure on the bottom wall, the deformation of the bottom wall of the battery pack case 1 is ultimately much greater than that of the side wall, and a large number of battery cells are installed on the bottom wall of the battery pack case 1. In order to increase the rigidity of the bottom wall of the battery pack case 1, that is, the bottom plate, if the number of lower reinforcing beams 13 on the bottom plate is directly increased, the size of the immersed liquid-cooled battery pack 100 will increase. Therefore, in the present application, convex ribs are stamped outward on the bottom wall of the battery pack case 1 to increase the strength and rigidity, which can stably support the battery module 2 and withstand the liquid pressure without increasing the size of the immersed liquid-cooled battery pack 100, thereby helping to improve the energy density of the immersed liquid-cooled battery pack 100.

[0068] Further, preferably, the convex ribs of the bottom wall of the battery pack case 1, i.e., the bottom convex ribs 16, include transverse convex ribs 161 extending along the length direction of the battery pack case 1 and longitudinal convex ribs 162 of the transverse convex ribs 161 extending along the width direction of the battery pack case 1. The number of longitudinal convex ribs 162 is multiple and is sequentially arranged at intervals along the length direction of the transverse convex ribs 161. The convex ribs in the two directions are interwoven to further improve the rigidity and strength. Of course, the structure of the convex ribs is not limited to the above, and can also be designed according to actual needs.

[0069] Further, preferably, Figure 8 As shown, the side wall of the battery pack body 1 is also punched out with a convex rib, namely a side convex rib 17, and the side convex rib 17 is in a straight-line structure extending along the length direction of the side wall.

[0070] It should be noted that the moment exerted on the side wall of the battery pack case 1 is not large, and the side wall is welded with an upper reinforcing beam 11 and is connected and reinforced by a supporting member 12, so it can effectively resist deformation. Therefore, the number of ribs stamped on the side wall of the battery pack case 1 is less than the number of ribs stamped on the bottom wall of the battery pack case 1. Of course, it is not limited to this and is designed according to actual needs.

[0071] In this embodiment, preferably, the upper reinforcing beam 11 , the lower reinforcing beam 13 , the supporting member 12 and the connecting member 14 are all iron sheet metal parts.

[0073] Further, preferably, the upper ribs, the lower reinforcing beam 13, the supporting member 12 and the connecting member 14 can be made of existing hot-dip galvanized sheet, but of course, it is not limited thereto and can be selected according to actual needs.

Any supporting member 12 can also be equipped with one connecting member 14 or more than two supporting members 12, such as three or four, etc.

[0078] In this embodiment, preferably, Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, there is one lower reinforcing beam 13, which extends along the bisector of the length direction of the bottom wall of the battery pack case 1, which supports the upper support member 12 more stably and occupies less space of the immersed liquid-cooled battery pack 100, which helps to improve the energy density. Of course, this is not limited to this.

[0081] According to the structure described above, the multiple cells in the battery module 2 are arranged in sequence along the length direction of the battery pack case 1, so the lower reinforcing beam 13 extends along its length direction, which is adapted to the arrangement direction of the cells, and the length of the connecting member 14 and the number of the supporting members 12 can be adjusted according to the number of cells. Of course, it is not limited to this, and can also be selected according to actual needs, for example: the lower reinforcing beam 13 extends along the width direction of the battery pack case 1, and the supporting member 12 extends along the length direction of the battery pack case 1, etc.
