Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a storage structure and energy storage battery system. Background Technology

[0002] Currently, existing energy storage systems typically include a battery compartment, a liquid cooling compartment, and an electrical compartment, which respectively house the battery modules, liquid coolers, and related electrical structures. To simplify the structure, a single cover plate is often used to uniformly cover all these compartments. However, this integrated covering method can easily lead to thermal interference, electromagnetic interference, or structural constraints between different compartments in practical applications. This is detrimental to the independent operation and maintenance of each functional module and also limits the safety and reliability of the system. Utility Model Content

[0003] This application provides a storage structure and an energy storage battery system to at least partially solve the above-mentioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, a storage structure is provided, comprising: a box body, a box cover, and a partition beam, wherein the partition beam is disposed in the box body, the box body has a mounting groove, the partition beam is configured to divide the mounting groove into a plurality of sub-grooves, so that the plurality of sub-grooves are isolated from each other, and the box cover includes a plurality of sub-covers, each sub-cover being in contact with a sub-groove.

[0005] It also includes a sealing element disposed between the sub-cover and the sub-groove to seal the gap between the sub-cover and the sub-groove.

[0006] By adopting the above technical solution, the installation slot is divided into multiple independent sub-slots, each equipped with a corresponding sub-cover and sealing element. This storage structure effectively avoids thermal interference, electromagnetic interference, and structural interference problems caused by sharing a cover between sub-slots. It achieves physical isolation and sealing protection for sub-slots with different functions, which not only improves the safety and stability of system operation, but also facilitates independent maintenance and modular management in the later stage. It has good engineering adaptability and practical value.

[0007] In one embodiment, the number of sub-tanks is three, namely a battery compartment, an electrical compartment, and a liquid cooling compartment.

[0008] By adopting the above technical solution, the internal functional modules of the energy storage system are clearly partitioned, and different types of structural components are placed in independent spaces. This effectively avoids electromagnetic interference from electrical components to battery modules, as well as the adverse effects of heat or condensation generated during the operation of the liquid cooling system on electrical safety and battery performance. Thus, the structural layout takes into account safety, reliability and heat dissipation efficiency, and improves the overall operating quality and integrated management capabilities of the energy storage system.

[0009] In one embodiment, the number of sub-covers is three, namely a first cover, a second cover, and a third cover, wherein the first cover is configured to cooperate with the battery compartment, the second cover is configured to cooperate with the electrical compartment, and the third cover is configured to cooperate with the liquid cooling compartment.

[0010] By adopting the above technical solutions, not only is the independence of each functional area in the closed structure further realized, but also, in the actual assembly and maintenance process, partial opening and operation can be carried out according to the usage requirements of different sub-tanks, avoiding structural disturbance and sealing damage caused by opening and closing the whole cover plate, effectively improving the modular management level and operation and maintenance convenience of the system, while enhancing the sealing and environmental isolation capabilities of each functional compartment in the closed state.

[0011] In one embodiment, the number of the separating beams is two, namely a first beam and a second beam, the first beam being configured to isolate the battery compartment and the electrical compartment, and the second beam being configured to isolate the battery compartment and the liquid cooling compartment.

[0012] By adopting the above technical solution, physical bidirectional isolation is achieved between the battery module and other functional modules, which can effectively prevent electromagnetic interference generated by the electrical structure and temperature and humidity changes that may be caused by the liquid cooling system from affecting battery performance and safety. This achieves multiple protections and independent operation of functional areas at the structural level, further enhancing the safety, reliability and system stability of the storage structure.

[0013] In one embodiment, the battery compartment is located in the middle of the cover, and the electrical compartment and the liquid cooling compartment are located on both sides of the battery compartment.

[0014] By adopting the above technical solution, the battery compartment is located in the middle of the cover, and the electrical compartment and liquid cooling compartment are arranged on its two sides. This not only helps to clearly divide the functional modules and reduce the risk of mutual interference, but also effectively keeps the center of gravity of the overall energy storage system in the center by placing the heavier battery module in the center of the structure. This improves the structural stability and stress balance of the equipment during handling, installation and operation, and further enhances the vibration resistance and safety reliability of the system.

[0015] In one embodiment, the connection between the partition beam and the inner wall of the box body is a full weld seal.

[0016] By adopting the above technical solutions, a high-strength and high-airtightness fixing effect can be achieved in the structure, avoiding gas, water vapor or electromagnetic leakage due to gaps, thereby ensuring tight isolation between each sub-tank and improving the overall sealing and protection capabilities of the storage structure.

[0017] In one embodiment, multiple screw holes are arranged on the opening edge of the box and on the partition beam, and the spacing between adjacent screw holes ranges from 90mm to 110mm.

[0018] By adopting the above technical solution, the sub-cover body can be stably fastened to the box body and the partition beam during the assembly process, so that the sealing components are evenly stressed when under pressure, thereby effectively improving the sealing performance and deformation resistance of the entire structure, avoiding air leakage, water seepage or structural loosening caused by uneven fastening or local stress concentration, and ensuring the airtightness and structural reliability of the storage structure during long-term operation.

[0019] In one embodiment, the spacing between adjacent screw holes is 100 mm.

[0020] By adopting the above technical solutions, the bolted connection achieves an optimal balance between structural stress and sealing performance, which not only facilitates standardization and improves operational efficiency during assembly, but also ensures that the seals are fully and evenly compressed during installation.

[0021] In one embodiment, the seal has a through hole corresponding to the screw hole, and a connecting nut is threaded between the screw hole and the through hole.

[0022] By adopting the above technical solution, the seal and the housing are fastened by connecting nuts, which can provide a stable and controllable clamping force during the assembly process, so that the seal can fully fit the contact interface.

[0023] In one embodiment, the seal is a silicone foam or a rubber gasket.

[0024] By adopting the above technical solution, the sealing element is set as silicone foam or rubber sealing gasket. Utilizing its excellent flexibility, resilience and temperature resistance, a stable and reliable sealing interface can be formed between the box body and the sub-cover body. Even under complex working conditions such as long-term operation or heat and pressure, it can still maintain a good sealing effect, thereby effectively preventing external moisture, dust or internal condensate from seeping in or leaking out, and improving the environmental adaptability and service life of the storage structure.

[0025] In one embodiment, the housing is provided with an air inlet, which is connected to the liquid cooling chamber.

[0026] By adopting the above technical solution, fresh air from outside can be effectively guided directly into the liquid cooling chamber, improving the air circulation and heat dissipation efficiency within the liquid cooling chamber. This enhances the thermal management performance of the liquid cooling module, reduces the overall system temperature, improves the operational stability and safety of the energy storage battery system, and prevents heat from accumulating inside the chamber.

[0027] In one embodiment, the enclosure is provided with a high-voltage connector, the first end of which is connected to the electrical compartment, and the second end of which is connected to the outside.

[0028] By adopting the above technical solutions, safe and efficient transmission of internal electrical signals and external equipment of the energy storage battery system is achieved. This ensures the sealing and protection performance of electrical connections, facilitates rapid system access and maintenance, effectively improves the integration and ease of use of the overall electrical architecture, and enhances the safety and reliability of system operation.

[0029] Secondly, embodiments of this application also provide an energy storage battery system, including the storage structure described in the first aspect, and further including battery modules and a liquid cooler. The battery modules are provided in multiple units, and the battery modules are installed in the battery compartment of the mounting slot. The liquid cooler is installed in the liquid cooling compartment of the mounting slot.

[0030] By adopting the above technical solution, multiple battery modules are directly installed in the battery compartment, and the liquid cooler is installed in the liquid cooling compartment. This achieves the integrated combination of battery modules in the large battery compartment, eliminating the intermediate structure from the traditional battery module to the plug box. This significantly reduces the use of the battery plug box and its related connecting harnesses and connectors, which not only simplifies the system structure and reduces material costs and assembly complexity, but also improves the overall reliability and heat dissipation performance of the battery cluster, and enhances the system's operating efficiency and maintenance convenience.

[0031] In one embodiment, the plurality of battery modules are connected in series via copper busbars.

[0032] By adopting the above technical solutions, not only is efficient current conduction between battery modules achieved and connection resistance reduced, but the reduction in the types of battery modules also simplifies the specifications and types of copper busbars, improves the versatility and applicability of copper busbars, thereby optimizing the system's manufacturing cost and assembly efficiency, while enhancing the overall electrical performance and reliability of the energy storage battery system.

[0033] In one embodiment, the battery compartment is provided with a plurality of crossbeams, which divide the battery compartment into a plurality of battery mounting areas, and each battery module is mounted in one of the battery mounting areas.

[0034] By adopting the above technical solution, multiple crossbeams are set in the battery compartment, dividing the battery compartment into multiple independent battery installation areas. This allows each battery module to be installed stably and orderly in its respective area, which not only effectively prevents mutual interference and displacement between battery modules, but also improves the mechanical strength and seismic performance of the overall structure. It also facilitates modular management and maintenance operations, further ensuring the safety, stability and reliability of the energy storage battery system.

[0035] In one embodiment, the battery module is connected to the crossbeam by bolts.

[0036] By adopting the above technical solution, a stable and detachable installation structure is achieved, which not only ensures that the battery module maintains a stable position during operation and reduces the risks caused by vibration and displacement, but also facilitates subsequent maintenance, replacement and repair operations, thereby improving the maintenance convenience of the energy storage battery system and the safety and reliability of the overall structure.

[0037] The beneficial effects of the embodiments of this application are as follows:

[0038] 1. This application divides the installation slot into multiple independent sub-slots, each equipped with a corresponding sub-cover and sealing element. This storage structure effectively avoids thermal interference, electromagnetic interference, and structural interference problems caused by the sharing of cover plates between sub-slots. It achieves physical isolation and sealing protection of different functional compartments, which not only improves the safety and stability of system operation, but also facilitates independent maintenance and modular management in the later stage. It has good engineering adaptability and practical value.

[0039] 2. This application achieves the integrated combination of battery modules within a large battery compartment by directly installing multiple battery modules in the battery compartment and installing the liquid cooler in the liquid cooling compartment. This eliminates the intermediate structure between the traditional battery module and the plug box, significantly reducing the use of the battery plug box and its related connecting harnesses and connectors. This not only simplifies the system structure and reduces material costs and assembly complexity, but also improves the overall reliability and heat dissipation performance of the battery cluster, and enhances the system's operating efficiency and maintenance convenience.

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0058] Firstly, this application provides a storage structure, please refer to... Figure 1 and Figure 2The storage structure includes a housing 1, a cover 2, and partition beams 3. The housing 1 has an installation slot 11, and the partition beams 3 are arranged within the housing 1 to divide the installation slot 11 into several independent sub-slots 111, ensuring effective isolation between the sub-slots 111. Each sub-slot 111 has a corresponding cover 21, which fits snugly against its corresponding sub-slot 111. A sealing element 4 is provided between the cover 21 and the sub-slot 111 to seal any gaps. This structure, through physical separation and sealing design, reduces the mutual interference between functional modules to a certain extent, thus improving the overall safety and reliability of the energy storage system.

[0059] For example, combined Figure 2 , Figure 3 The number of sub-tanks 111 is three, namely battery compartment 111a, electrical compartment 111b and liquid cooling compartment 111c.

[0060] In some embodiments, combined with Figure 2 , Figure 3 Two partition beams 3 are provided, designated as the first beam 31 and the second beam 32. The first beam 31 isolates the battery compartment 111a from the electrical compartment 111b, while the second beam 32 isolates the battery compartment 111a from the liquid cooling compartment 111c. This arrangement of partition beams 3 structurally achieves bidirectional separation between the battery module and other functional modules, which helps reduce the impact of electromagnetic interference from the electrical structure and temperature and humidity changes that may be caused by the liquid cooling system on battery performance and safety, thereby enhancing the functional independence and multi-layered protection capabilities of the storage structure.

[0061] It is worth noting that the partition beam 3 is connected to the inner wall of the box 1 by a full welded seal. The full welded seal plays a key role in structural strength and sealing performance, and can prevent gas, water vapor or electromagnetic leakage caused by gaps to a certain extent. This helps to ensure tight isolation between each sub-tank 111, strengthens the sealing and protection capabilities of the storage structure, and improves the stability of the overall system.

[0062] In some examples, the cover 2 is composed of multiple sub-covers 21, each corresponding to a sub-slot 111. Specifically, there are three sub-covers 21: a first cover 211, a second cover 212, and a third cover 213, corresponding to the battery compartment 111a, the electrical compartment 111b, and the liquid cooling compartment 111c, respectively. This design enhances the independence of each functional area, allowing for partial opening during assembly and maintenance. This helps reduce structural disturbances and seal damage that may be caused by opening and closing the entire cover, improving the modular management level of the system and the convenience of operation and maintenance. Meanwhile, the seal 4 uses silicone foam or rubber gaskets, utilizing their flexibility and temperature resistance to allow the sealing interface to adapt to thermal expansion and contraction and compression deformation under long-term operating conditions, ensuring a good sealing effect. This helps prevent the infiltration and leakage of external moisture, dust, or internal condensate, improving the environmental adaptability and service life of the storage structure.

[0063] In some implementations, combined Figure 1 , Figure 4 To ensure a reliable connection between the seal 4 and the housing 1, the seal 4 and the housing 1 are fastened by bolts, so that the seal 4 can fit evenly against the contact surface under pressure, which enhances the stability of the sealing effect and facilitates the later maintenance and replacement of the seal 4.

[0064] For example, multiple screw holes 5 are arranged on the edge of the opening of the box 1 and the partition beam 3, and the spacing between adjacent screw holes 5 is controlled within the range of 90mm to 110mm, with 100mm as the optimal spacing. This design enables a stable and uniform distribution of fastening force between the sub-cover 21 and the box 1 and the partition beam 3 during assembly, which helps to prevent the seal 4 from deforming or leaking due to uneven force, improves the airtightness and deformation resistance of the entire storage structure, and enhances the stability and reliability of the structure.

[0065] For example, the seal 4 has a through hole 51 corresponding to the screw hole 5, and a connecting nut 51 is threaded between the screw hole 5 and the through hole 51.

[0066] In some alternative embodiments, the sealing requirements of the electrical compartment 111b and the liquid cooling compartment 111c can be appropriately reduced to meet the technical and cost balance in practical applications. Given that the electrical compartment 111b is mainly used to house electrical structures, and the liquid cooling compartment 111c mainly undertakes the installation and heat dissipation functions of the liquid cooler 8, the electrical compartment 111b and the liquid cooling compartment 111c are less sensitive to sealing performance than the battery compartment 111a. Therefore, the material selection and sealing degree of their sealing elements 4 can be appropriately relaxed, and they do not need to meet the strict airtightness standards of the battery compartment 111a. By rationally designing the sealing structure of the electrical compartment 111b and the liquid cooling compartment 111c, such as using a sealing gasket with good elasticity but an appropriate sealing level, or reducing the sealing surface width of the sealing element 4, while maintaining the structural integrity of the partition beam 3 and the housing 1, sealing costs can be reduced while effectively avoiding assembly difficulties and maintenance inconveniences caused by excessive sealing.

[0067] It is understandable that this moderate reduction in sealing requirements will not significantly affect the overall performance of the battery cluster, as the core component, battery module 7, is housed within the highly sealed battery compartment 111a, ensuring a stable environment and safe operation for battery module 7. Meanwhile, the functional characteristics and internal environment of the electrical compartment 111b and the liquid cooling compartment 111c mean that moderate gas or heat exchange is actually beneficial for system heat dissipation and the operational stability of electrical equipment, thus achieving a good balance in overall system performance.

[0068] In some implementations, combined with Figure 2 , Figure 3 The battery compartment 111a is located in the center of the cover 2, while the electrical compartment 111b and liquid cooling compartment 111c are located on either side of the battery compartment 111a. Multiple battery modules 7 are installed in the battery compartment 111a, while the electrical compartment 111b and liquid cooling compartment 111c house corresponding functional components. This layout not only achieves clear zoning and independent operation of the functional modules but also helps to center the battery modules 7, which are relatively heavy components, thus concentrating the overall center of gravity of the energy storage system. This is beneficial for structural stability and stress balance, and improves the vibration resistance and safety reliability of the equipment during handling, installation, and operation.

[0069] In some implementations, combined with Figure 1 , Figure 5 To facilitate heat dissipation in the energy storage system, an air inlet 12 is provided on the housing 1, which is connected to the liquid cooling chamber 111c. This structure allows external air to be directly introduced into the liquid cooling system, enhancing air circulation and heat exchange, which helps to reduce system temperature and improve the operational stability and safety of the energy storage battery system.

[0070] For example, combined Figure 2 , Figure 3The enclosure 1 is also equipped with a high-voltage connector 6. One end of the high-voltage connector 6 is connected to the electrical compartment 111b, and the other end of the high-voltage connector 6 is connected to the outside world, so as to realize the safe and efficient transmission of electrical signals inside the energy storage system and external equipment, improve the sealing and protection performance of the electrical connection, facilitate the system to be quickly connected and maintained, and improve the integration and ease of use of the overall electrical architecture.

[0071] Secondly, this application provides an energy storage battery system, including the storage structure of the first aspect, and further including battery modules 7 and liquid coolers 8. Multiple battery modules 7 are provided, with each battery module 7 installed within a battery compartment 111a and the liquid cooler 8 installed within a liquid cooling compartment 111c. It can be understood that the battery modules 7 are directly installed in the battery compartment 111a, and the liquid cooler 8 is installed within the liquid cooling compartment 111c, achieving integrated assembly of the battery modules 7 within the large battery compartment 111a. This eliminates the traditional intermediate structure between the battery modules 7 and the charging box, reducing the use of battery charging boxes and related connecting harnesses and connectors, simplifying the system structure, reducing material costs and assembly complexity, while simultaneously improving the overall reliability and heat dissipation performance of the battery cluster, enhancing system operating efficiency and maintenance convenience.

[0072] In some implementations, combined with Figure 2 , Figure 3 and Figure 5 In terms of the connection method of battery module 7, multiple battery modules 7 are connected in series through copper busbars. This connection method not only promotes efficient current transmission and reduces connection resistance, but also reduces the specifications and types of copper busbars due to the relatively small number of types of battery modules 7. This improves the versatility and applicability of copper busbars, helps to reduce manufacturing costs and assembly complexity, and enhances the electrical performance and reliability of the system.

[0073] For example, the battery compartment 111a is provided with multiple crossbeams 9, dividing the battery compartment 111a into several battery mounting areas 91. Each battery module 7 is securely installed in its corresponding battery mounting area 91, preventing mutual interference and displacement between battery modules 7, improving mechanical strength and shock resistance, and facilitating modular management and maintenance. The battery modules 7 are bolted to the crossbeams 9, forming a stable and detachable structure, which facilitates subsequent maintenance and replacement operations.

[0074] Based on this, by combining physical separation and sealing design of the battery system's enclosure 1 with a reasonable structural layout and connection method, the problems of mutual interference and inconvenience in maintenance caused by the unified cover of multiple compartments in the existing technology are improved to a certain extent. This promotes the improvement of the safety, reliability and operating efficiency of the energy storage system, and provides a storage structure and overall battery system solution that is structurally reasonable, functionally independent and easy to maintain for the energy storage field.
