In related technologies, due to the insufficient structural strength and carrying capacity of energy storage containers, energy storage containers are often damaged or scrapped prematurely. For example, in the energy storage containers that integrate 5MWh and 6MWh respectively under the condition of a 20-foot standard high cabinet, the weight of the energy storage containers is about 43t and more than 50t, respectively, which has greatly exceeded the maximum load of about 40t of the 20-foot standard high cabinet energy storage container, which brings potential risks of uncertainty to the logistics and transportation of energy storage containers.

Typically, the door 32 can be rotatably connected to the frame 10 using some rotating connectors 34. The rotating connectors 34 can be commonly used hinges or other types of hinges. For example, a hinge can be installed on the surface of the second corner column 112 adjacent to the door 32. The hinge is connected between the second corner column 112 and the door 32, thereby allowing the door 32 to be rotatably set on the frame 10. In the embodiment of the present application, the third section 11221 and the fourth section 11222 can be distributed along the thickness direction of the warehouse door 32, wherein the third section 11221 is located on the side of the warehouse door 32 away from the battery rack 20, and the fourth section 11222 is located on the side of the third section 11221 facing the warehouse door 32, and the second connecting section 11223 is bent and connected between the third section 11221 and the fourth section 11222 and is arranged parallel to the thickness direction of the warehouse door 32, thereby forming an assembly space 1120 facing the warehouse door 32 on the second outer wall 1122, and the hinge is arranged in the assembly space 1120 and connects the fourth section 11222 and / or the second connecting section 11223.

In order to facilitate mounting the side panel 31 on the frame 10, in some embodiments, the eighth section 11322 can be set to be closer to the side panel 31 than the seventh section 11321 in the direction from the fourth outer wall 1132 to the fourth inner wall 1131 (i.e., the thickness direction of the side panel 31), or the eighth section 11322 can be set to be flush with the side panel 31, thereby making the avoidance space 1130 closer to the side panel 31 or making the avoidance space 1130 flush with the surface of the side panel 31. When 31 is assembled on the frame 10, or when the side panel 31 needs to be disassembled due to maintenance, some installation tools (such as wrenches and screwdrivers are more common) are needed to install and disassemble the side panel 31. Due to the existence of the avoidance space 1130, during this operation, the installation tool or the hand operating the installation tool, or part of the installation tool and part of the hand can be located within the avoidance space 1130, thereby reducing or even avoiding the interference between the installation tool or the hand and the fourth corner column 113, so that the maintenance personnel can be more handy when installing and disassembling the side panel 31, thereby improving the convenience of installation and disassembly and improving the efficiency of installation and disassembly.

[0081] See also Figure 2Each battery rack 20 may also include a plurality of bearing rails 24, which are arranged between the first crossbar 21 and the second crossbar 22 at intervals and can be connected to at least two vertical bars 23.

The plurality of bearing rails 24 of one battery rack 20 are arranged at the same height and opposite to the plurality of bearing rails 24 of the other battery rack 20. A bearing space for installing a battery pack is formed between the two bearing rails 24 of the same height and opposite to each other between the two battery racks 20, and the bearing space gradually narrows from the first side 130 to the second side 140. Please refer to Fig.15 , Fig.15 An exploded schematic diagram of a bearing rail provided in an embodiment of the present application. To facilitate placing a battery pack on two bearing rails 24 disposed opposite to each other between two battery racks, each bearing rail 24 may include a bearing portion 241 and a guide portion 242, wherein the bearing portion 241 is connected to at least two uprights 23 at the same time, and the guide portion 242 is fixed to the bearing portion 241, and the guide portion 242 has an end close to the first side 130 and an end close to the second side 140, and the thickness of the guide portion 242 gradually increases from the first side 130 to the second side 140, so that the space between the two bearing rails 24 disposed opposite to each other at the same height can gradually become narrower in the direction from the first side 130 to the second side 140, thereby enabling the two guide portions 242 disposed opposite to each other at the same height to play a better guiding role in the process of pushing the battery pack into the bearing rail 24, thereby preventing the battery pack from deviating from the desired pushing direction when being pushed in.

[0082] Please continue reading Fig.16 , Fig.162 is a schematic diagram of the structure of the load-bearing portion 241 provided by an embodiment of the utility model. In some embodiments, the load-bearing portion 241 may include a load-bearing member 2411 and a connecting member 2412, the load-bearing member 2411 is used to carry the battery pack, and the connecting member 2412 is used to securely connect the load-bearing member 2411 to the vertical pole 23. Specifically, the load-bearing member 2411 may include a load-bearing edge 24111 and a limiting edge 24112, the load-bearing edge 24111 and the limiting edge 24112 intersect, for example, the load-bearing edge 24111 and the limiting edge 24112 may be connected vertically or tending to be vertical, wherein the load-bearing edge 24111 is used to carry the battery pack, and the limiting edge 24112 is connected to the vertical pole 23, and the limiting edge 24112 is used to limit the movement direction of the battery pack to ensure that the direction of the battery pack will not be offset when it is pushed into the carrying space. The connecting member 2412 can be a 45-degree bending member. The connecting member 2412 can include a first connecting edge 24121 and a second connecting edge 24122. The first connecting edge 24121 can be connected to the vertical pole 23, and the second connecting edge 24122 can be connected to the load-bearing edge 24111 to support the load-bearing edge 24111. A reinforcing structure 24123 can also be provided between the first connecting edge and the second connecting edge of the connecting member 2412 to improve the structural strength of the connecting member 2412. For example, a bulge or a rib can be designed between the first connecting edge 24121 and the second connecting edge 24122. Taking the bulge as an example, the bulge can be provided at one end of the first connecting edge 24121 close to the second connecting edge 24122 to abut against the second connecting edge 24122.

[0083] In some embodiments, the guide portion 242 may include a guide member 2421 and a plurality of pads 2422, the guide member 2421 may include a guide edge 24211, and after the guide member 2421 is assembled to the bearing portion 241, the guide edge 24211 of the guide member 2421 will be attached to the limiting edge 24112 of the bearing member 2411, and the pads 2422 may be arranged at intervals from the first side to the second side (i.e., along the length direction of the limiting edge 24112) and sandwiched between the guide edge 24211 and the limiting edge 24112. , or a part of the pad 2422 is clamped between the guide edge 24211 and the limiting edge 24112, and the other part of the pad 2422 is arranged on the side surface of the guide edge 24211 away from the limiting edge 24112. In the direction from the first side to the second side, the thickness of the guide edge 24211 and / or the pad 2422 can be set to increase successively. Specifically, the thickness of the guide edge can be set to increase successively from the first side to the second side, and multiple pads can be stacked and used, or several pads with different thicknesses can be designed. Exemplarily, when a pad is attached to one end of the limiting edge 24112 close to the first side 130, pads may not be stacked, or a pad with a smaller thickness may be directly used, and when a pad is attached to the other end of the limiting edge 24112 close to the second side 140, two or more pads may be stacked, or a pad with a larger thickness may be used. In this way, the bearing space between two equal and opposite bearing guide rails 24 can gradually narrow from the first side to the second side, thereby having an effective guiding effect on the process of pushing the battery pack. Of course, the implementation method of using a guide edge with a thickness that increases successively along the length direction can also have an effective guiding effect on the process of pushing the battery pack. Alternatively, under the premise of using a guide edge with a thickness that increases successively along the length direction, pads of different thicknesses can be used or stacked, which can also have an effective guiding effect on the process of pushing the battery pack. Those skilled in the art may choose one of the above-mentioned optional methods or use them in any combination as appropriate.

[0084] In some embodiments of the present application, the pad 2422 clamped between the guide edge 24211 and the limiting edge 24112 can be made of sheet metal, polycarbonate (PC) or any other suitable material. The pad 2422 arranged on the side of the guide edge 24211 away from the limiting edge 24112 is in direct contact with the surface of the battery pack. Therefore, the pad used in this case can be made of a relatively soft material such as rubber, silicone, etc., so as to cushion the impact on the battery pack when the battery pack is pushed.

[0085] See also Figure 1The energy storage container 1 may further include a top plate 33 disposed on the top side 120 of the frame 10, and at least a portion of the top plate 33 is arched in a direction away from the top side 120. Exemplarily, in some embodiments, the middle portion of the top plate 33 may be arched in a direction away from the top side 120 of the frame 10 by a preset height, for example, a spacing of 10 mm may be provided between the middle portion of the top plate 33 and the top side 120 of the frame 10. Such a design has the advantage that when the energy storage container 1 is used in an outdoor environment, the top of the energy storage container 1 can conveniently drain water and snow. Alternatively, in other embodiments, on two opposite sides of the top plate 33, the distance between one side of the top plate 33 and the top side 120 of the frame 10 can be designed to be greater than the distance between the other side of the top plate 33 and the top side 120 of the frame 10, that is, the top plate 33 and the top side 120 of the frame 10 are arranged at an angle, and the top plate 33 is inclined relative to the top side 120 of the frame 10. In this way, when the energy storage container 1 is used in an outdoor environment, it can also effectively prevent water and snow from accumulating on the top of the energy storage container 1.

[0086] Please continue reading Figure 1 In some embodiments, the energy storage container 1 may further include a plurality of explosion relief plates 331, and one or more of the side plates 31, the door 32, and the top plate 33 may be provided with a plurality of explosion relief ports, and one explosion relief plate 331 is provided to cover one explosion relief port, and the strength of the explosion relief plate 331 is set to be less than the strength of the side plates 31, the door 32, and the top plate 33. Exemplarily, the top plate 33 of the energy storage container 1 may be provided with five explosion relief ports, and each explosion relief port is covered with an explosion relief plate 331. When some unexpected situations occur, such as when the battery pack explodes due to thermal runaway, the explosion energy may cause the explosion relief plate 331, which is a weak area, to be exploded first, and the internal space of the energy storage container 1 may be connected to the external space through the explosion relief ports, and some combustible gases may be released outward from the explosion relief ports first, thereby minimizing the damage to the energy storage container 1.

The advantage of such a design is that when the support beam 40 of the energy storage container is subjected to external forces in the direction of gravity during use, the web 43 can decompose these external forces into downward forces in the direction of gravity and forces along the length direction of the web 43, which can help alleviate the degree of deformation of the web 43 toward the bottom side 110, and ultimately achieve the improvement of the carrying capacity of the energy storage container.

[0095] In order to facilitate those skilled in the art to better understand the structure of the support beam provided in the embodiment of the present application, the assembly process and implementation principle of one of the support beams provided in the embodiment of the present application are schematically described here. In some embodiments of the present application, at least a portion of the first side of the web can be an arcuate side, the second side of the web can be a straight side, and at least a portion of the first side is bent in the direction of the second side. For example, the middle part of the web of the first side of the web can be formed into an arcuate side in the top side direction, so that the distance between the first side of the web and the second side of the web includes a first distance between the middle part of the first side and the second side, and a second distance between the end of the first side and the second side. After testing, the inventor found that when the difference between the first distance and the second distance is 15mm-25mm, that is, when the maximum spacing between the middle part of the web and the first wing is 15mm-25mm, the support beam can obtain the optimal stiffness and strength, thereby enabling the energy storage container to have the best carrying capacity. In the example of connecting the web to the first wing plate and the second wing plate in sequence, first, the two ends of the first side of the web can be abutted against the surface of the first wing plate. In this case, it can be observed that a gap is formed between the middle of the web and the surface of the first wing plate. Then, solder can be filled into the gap so that the first side of the web and the first wing plate can be connected by a welding process. Thereafter, the second side of the web is abutted against the surface of the second wing plate. Then, solder is applied near the abutting position between the second side of the web and the second wing plate, so that the second side of the web and the second wing plate can also be connected by a welding process. In some embodiments, the web, the first wing plate, and the second wing plate can be arranged orthogonally or nearly orthogonally to each other, so that the support beam has an "I"-shaped cross-section that is perpendicular to its length direction. Practice has shown that the support beam with an "I"-shaped cross-section has better rigidity and strength. During actual use, when the support beam is subjected to force in the direction of gravity, the web can decompose these forces into force in the direction of gravity and force along the length direction of the support beam, thereby alleviating the degree of deformation of the support beam toward the bottom side under the action of external force. Since a gap is formed between the middle part of the web and the surface of the first wing plate, and the strength of the solder used for welding the web and the first wing plate in the embodiment of the present application is less than the strength of the web, when the support beam is subjected to a larger force in the direction of gravity, the middle part of the web can also move toward the direction of the first wing plate, and finally the middle part of the web is completely in contact with the first wing plate, thereby effectively limiting the deformation of the web.

[0096] In the embodiment of the present application, the support beam 40 is pre-arc-edged before being put into use, and the support beam 40 is connected to each battery rack 20. Compared with the support beam 40 without the arc-edged process, the advantage of such a design is that when the support beam 40 is subjected to an external force in the direction of gravity, the ability of the support beam 40 to deform toward the bottom side 110 can be effectively reduced, thereby greatly improving the stiffness and strength of the support beam 40, thereby effectively improving the carrying capacity of the energy storage container 1 and extending the service life of the energy storage container 1.

[0097] See also Figure 4 , Fig. 9 and Fig.14, at least one battery rack 20 may further include a support member 26, and each support member 26 connects the second wing plate 42, the bottom side 110, the top side 120, the first side 130, and the second side 140.

It is understandable that the support body may also include only one second column 265 without the first connecting rod 266. In this embodiment, the second column 265 connects the first crossbar 21, the second crossbar 22, and the third crossbar 25, or the second column 265 connects the second crossbar 22 and the third crossbar 25, and the second column 265 connects the first support rod 261, the second support rod 262, the third support rod 263, and the fourth support rod 264. When the energy storage container 1 is subjected to force, the first crossbar 21, the second crossbar 22, the third crossbar 25, the first support rod 261, the second support rod 262, the third support rod 263, and the fourth support rod 264 can transfer the force exerted on the energy storage container 1 from multiple directions (for example, from the bottom side, the top side, the first side, and the second side) to the support body, and the support body then transfers the force exerted to the support beam 40. Therefore, the support member 26 can be used to further improve the structural strength of the frame 10 and extend the service life of the energy storage container 1.

Fig.17 The support beam 40 includes a first wing plate 41, a second wing plate 42 and a web plate 43. The web plate 43 is connected between the first wing plate 41 and the second wing plate 42.

[0114] In summary, the beneficial effects of the energy storage container provided by the embodiment of the present application are as follows: first, by providing a storage space for accommodating at least part of the battery rack, an installation space for installing the rotating connector 34, and a storage space for accommodating the pipe on the corner column, it is beneficial to improve the structural compactness of the energy storage container; second, by recessing part of the wall of the first cross beam along its length direction to form a storage groove, the storage groove can accommodate the bottom end of the locking rod of the warehouse door, which can further improve the structural compactness of the energy storage container; third, by processing the first side of the web of the support beam with an arc-shaped edge process before putting it into use, and connecting the support beam to each battery rack, there is no gap with the web. Compared with the support beam treated with the arc-shaped edge process, the advantage of this design is that when the support beam is subjected to an external force in the direction of gravity, the ability of the support beam to deform toward the bottom side can be effectively reduced, thereby greatly improving the stiffness and strength of the support beam, thereby effectively improving the carrying capacity of the energy storage container and extending the service life of the energy storage container; fourthly, by arranging support members on at least two battery racks, the support members are simultaneously connected to the support beam, the bottom side, the top side, the first side and the second side. When the energy storage container is subjected to force, the support members can transfer the force to the support beam.
