Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the protection scope of the utility model.

[0025] As Figures 1 to 6 Indicated, first aspect, an embodiment of the utility model provides a kind of energy storage container 1, energy storage container 1 includes: box 10, with first containing cavity 11;Barrier 20 is arranged in first containing cavity 11 and is sealedly connected with first containing cavity 11, to first containing cavity 11 is divided into cooling cabin 111 and electrical cabin 112 sequentially arranged along the height direction of box 10, electrical cabin 112 is below cooling cabin 111, cooling cabin 111 is used to contain cooling assembly, electrical cabin 112 is used to contain electric element, liquid inlet line 30 and liquid outlet line 40;At least two connecting pieces 50, with barrier 20 wear and connect and seal fixedly, one end of connecting piece 50 is located in cooling cabin 111, the other end of connecting piece 50 is located in electrical cabin 112, one of connecting piece 50 two ends are respectively connected with the liquid outlet of cooling assembly and one end of liquid outlet line 40, the other connecting piece 50 two ends are respectively connected with the liquid inlet of cooling assembly and one end of liquid inlet line 30.

[0026] The technical scheme is applied to the utility model, the first accommodating cavity 11 is divided into the cooling cabin 111 and the electrical cabin 112 in turn along the height direction of the box body 10 by setting the blocking piece 20 in the first accommodating cavity 11, and the first blocking piece 20 is sealingly connected with the first accommodating cavity 11, so that the liquid in the cooling cabin 111 can be prevented from flowing into the electrical cabin 112, thereby ensuring the stability of the electrical cabin 112 when the components in the electrical cabin 112 operate, and at least two connecting pieces 50 are arranged on the blocking piece 20 and sealingly fixed with the blocking piece 20, one end of the connecting piece 50 is located in the cooling cabin 111, the other end of the connecting piece 50 is located in the electrical cabin 112, both ends of one of the connecting pieces 50 are connected with the liquid outlet of the cooling assembly and one end of the liquid outlet pipeline 40 respectively, both ends of the other connecting piece 50 are connected with the liquid inlet of the cooling assembly and one end of the liquid inlet pipeline 30 respectively, so that the cooling assembly can cool the external assembly while preventing the liquid from flowing into the electrical cabin 112, thereby improving the protection level of the electrical cabin 112 to meet the use requirement of the user.

[0027] In an embodiment, the blocking piece 20 is welded to the inner wall of the first accommodating cavity 11. The welding connection tightly combines the blocking piece 20 and the inner wall of the first accommodating cavity 11 together by means of molten metal, forming a high-strength connection. The strength of this connection method is usually close to or equal to the strength of the original material, so it can withstand a large pressure and tension and is not prone to breaking or leaking. At the same time, during the formation process of the welding connection, the molten metal fills the weld, forming a dense metal structure. This structure can effectively prevent the leakage of liquids and other media through the weld, thereby improving the sealing performance. Especially in equipment that needs to withstand high pressure or high vacuum environment, the sealing performance of the welding connection is particularly important. Furthermore, by selecting appropriate welding processes and materials, a firm connection between different materials can be achieved while maintaining good sealing effect. In order to improve the sealing performance of the welding connection, the welding process and material can be optimized. For example, selecting an appropriate welding method (such as TIG welding) can reduce problems such as porosity and slag inclusion in the weld, thereby improving the sealing performance. At the same time, selecting welding materials that are the same as or similar to the connected materials can also achieve better sealing effect.

[0028] In an embodiment, the connecting piece 50 includes: a body 51 connected with the blocking piece 20; and a protruding portion 52 protruding along the circumference of the outer side wall of the body 51 and arranged on the body 51, the protruding portion 52 being located in at least one of the cooling cabin 111 and the electrical cabin 112. In this way, the protruding portion 52 can be clamped and matched with the clamps on the liquid outlet and the liquid inlet of the cooling assembly, the liquid inlet pipeline 30 and the liquid outlet pipeline 40, to realize the fixation between them. The above structure is simple, and the remaining disassembly can not only improve the disassembly efficiency between components, but also meet the connection requirements between components.

[0029] In an embodiment, the protrusions 52 are arranged in a circumferential ring along the outer sidewall. The circumferential arrangement of the protrusions 52 can uniformly distribute pressure across the entire outer sidewall, thereby enhancing the overall stability of the structure. This design can more effectively disperse stress when subjected to external forces, reducing the risk of localized damage. At the same time, the circumferential protrusions 52 can increase the connection area, thereby improving the connection strength, so as to improve the connection strength of the connecting piece 50.

[0030] In an embodiment, the barrier 20 is provided with a groove 21, the opening of the groove 21 is arranged towards the cooling cabin 111, and the protrusion 52 is located in the groove 21. Since the bottom of the cooling assembly is in plane contact with the barrier 20, the part of the barrier 20 to be placed on the connecting piece 50 is designed as a concave structure, ensuring that the protrusion 52 is aligned with the bottom of the cooling assembly. Thus, the cooling assembly and the connecting piece 50 are conveniently arranged.

[0031] In an embodiment, the energy storage container 1 further comprises a drainage device 60, a drainage pipe is sequentially connected with the barrier 20 and the electrical cabin 112, and one end of the drainage pipe is located in the cooling cabin 111 and / or the groove 21, and the other end of the drainage pipe is located outside the box body 10. During the operation of the cooling assembly, due to the change of temperature and the circulation of cooling liquid, excess or accumulated cooling liquid may be generated. The drainage device 60 can provide an effective outlet to timely drain the excess cooling liquid, so as to prevent the cooling liquid in the cooling assembly from being too much to cause pressure rise or affect the cooling effect. At the same time, the long-term accumulated cooling liquid may be deteriorated due to evaporation, oxidation, etc., and produce corrosive substances. If these corrosive substances are not timely drained, they may corrode the internal components of the cooling assembly, causing component damage or performance degradation. The drainage device 60 can regularly drain the cooling liquid which may contain corrosive substances, thereby protecting the internal components of the cooling assembly from corrosion.

[0032] Further, the cooling assembly generates a certain pressure inside during operation. The drainage device 60 can release the pressure in the system when necessary, maintaining the pressure balance of the system. This is of great significance to prevent the system from being damaged or leaking due to excessive pressure. When the cooling assembly is maintained or the cooling liquid is replaced, the drainage device 60 provides a convenient drain port. By opening the drainage device 60, the cooling liquid in the cooling assembly can be easily emptied, providing convenience for maintenance or replacement work. The effective work of the drainage device 60 can ensure that the cooling assembly always maintains the best working state. By timely draining the excess or deteriorated cooling liquid, and maintaining the pressure balance of the system.

[0033] In an embodiment, the outer diameter of the protrusion 52 is L, where 76.5mm≤L≤78.5mm. By setting the outer diameter of the protrusion 52 within this range, it is beneficial for the standardized production of the product. This not only improves production efficiency, but also reduces production costs, as standardized production generally means less customization and higher production efficiency. At the same time, the standardized outer diameter size makes the protrusion 52 more interchangeable in different assemblies or equipment. This means that when replacement or maintenance is needed, it is easier to find suitable replacement parts, reducing delays and cost increases due to size mismatches. Furthermore, the outer diameter range of 76.5mm to 78.5mm enables the protrusion 52 to be adapted to a variety of different application scenarios and equipment. This flexibility makes the protrusion 52 more versatile in the design and manufacturing process, and can meet a wider range of needs.

[0034] Further, the standardized outer diameter size also helps to improve the compatibility between the protrusion 52 and other components. For example, during the connection 50 or assembly process, the outer diameter size of the protrusion 52 conforms to the standard, making it easier to cooperate with other components, ensuring the firmness and sealing of the connection. At the same time, under certain material and process conditions, the outer diameter size of the protrusion 52 has an important influence on its strength and durability. By setting the outer diameter within the range of 76.5mm to 78.5mm, it is generally possible to ensure that the protrusion 52 has sufficient strength and durability to meet the use requirements.

[0035] In an embodiment, the barrier 20 is a roll forming structure. First, the production efficiency of the roll forming process can be increased by more than 10 times compared to punching and bending processes. This high efficiency makes roll forming particularly suitable for mass production, which can significantly reduce production costs. At the same time, roll forming is not limited by product length and can be produced continuously, thereby improving the overall efficiency of the production line. And compared with hot rolling and stamping processes, roll forming can save 15% to 30% of materials. This is mainly because roll forming can more accurately control the deformation of the material, reducing material waste. Furthermore, roll forming is suitable for a variety of metal materials, including low-carbon steel, non-ferrous metals, etc., further improving material utilization.

[0036] Further, roll forming can achieve high-precision size control to meet high-precision requirements. This is due to the precise configuration of the multi-pass forming rollers and the continuous bending of the metal strip during the roll forming process. The surface quality of the roll forming product is good, and the dimensional accuracy is high, which can meet the needs of various complex cross-section profiles. And the noise generated during the roll forming process is low, which is beneficial to improve the working environment and reduce noise pollution.

[0037] In an embodiment, the box 10 further comprises a second accommodating cavity 12, which is arranged along the length direction of the box 10 and is used for accommodating a battery module, and a cooling assembly is used for cooling the battery module. In this way, the stability of the battery module during operation can be ensured by using the cooling assembly in the first accommodating cavity 11 to cool the battery module.

[0038] In a second aspect, the embodiments of the utility model provide a kind of energy storage system, comprising above-mentioned energy storage container 1.
