Description

Technical Field

[0001] This utility model relates to the field of energy storage system technology, and in particular to an energy storage container system. Background Technology

[0002] With the rapid development of new energy technologies, energy storage battery systems, represented by lithium-ion batteries, have been widely used in renewable energy consumption, grid peak shaving and frequency regulation, and emergency backup power. To meet the demand for large-capacity energy storage, energy storage batteries are usually composed of battery packs as basic units, which are combined in series and parallel to form battery pack arrays. Multiple battery pack arrays are then arranged in a container to form an integrated containerized energy storage system.

[0003] During the actual operation of containerized energy storage systems, the battery packs generate a significant amount of heat due to electrochemical polarization and ohmic losses during charging and discharging, leading to elevated battery temperatures. Temperature is a critical factor affecting battery performance, lifespan, and safe operation. Excessively high temperatures not only accelerate the degradation of active materials within the battery, reducing energy storage efficiency and cycle life, but can also trigger serious safety accidents such as thermal runaway. Therefore, effectively controlling the temperature of the battery packs within the container and maintaining them within a suitable operating temperature range (typically 25℃-35℃) is one of the core technical requirements for ensuring the reliable operation of the energy storage system. Battery packs located in the middle section, in particular, have a higher concentration of heat, and cooling failure can easily lead to safety accidents.

[0004] In addition, related technologies often employ a composite temperature control structure of "liquid cooling + air conditioning" for cooling solutions of containerized energy storage systems. On the one hand, liquid cooling devices are installed on the side walls of the container, and heat is exchanged with each battery pack through liquid cooling pipes or liquid cooling plates to directly remove the heat generated by the battery packs. On the other hand, air conditioning equipment is installed on the front side wall of the container to indirectly assist in cooling the battery packs by regulating the overall ambient air temperature inside the container. This structure is complex and not conducive to cooling battery packs located in the middle of the container. Utility Model Content

[0005] The purpose of this invention is to provide an energy storage container system that solves the problem that the temperature control system of existing energy storage containers is complex and not conducive to cooling the battery packs located in the middle of the container. The energy storage container system of this invention has a simple structure and is easy to cool the battery structure in the middle.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An energy storage container system, comprising:

[0008] The housing includes a battery compartment, in which a first battery structure, at least one second battery structure, and a third battery structure are sequentially spaced along a first horizontal direction. The bottom of the housing is provided with multiple battery cooling zones spaced along the first horizontal direction, wherein at least one second battery structure corresponds to two of the battery cooling zones.

[0009] Multiple direct cooling devices are installed at intervals on the top of the housing along the first horizontal direction. The direct cooling devices are used to cool the battery structure and / or the battery cooling area.

[0010] The beneficial effects of this utility model are:

[0011] The energy storage container system provided by this utility model has at least one second battery structure in the middle, corresponding to two battery cooling zones. When one battery cooling zone cannot cool the second battery structure, the other battery cooling zone can continue to cool the second battery structure, maintaining a certain cooling effect, reducing the probability of heat concentration, and reducing thermal runaway. The direct cooling device is located at the top of the container, avoiding occupying the internal space of the battery compartment, improving the space utilization rate of the battery compartment, and increasing the energy storage density. In addition, the direct cooling device can cool the battery structure and / or the battery cooling zone, simplifying the overall structure and making assembly easier. The direct cooling device is centrally arranged at the top of the container, and the battery cooling zone is centrally arranged at the bottom of the container, with clear functional zoning, avoiding the intersection of pipes and lines in each area, and simplifying the overall structural design and installation process.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0017] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0020] An energy storage container is a device that uses a container as a carrier to store energy through rows of battery packs installed inside the container. The container typically contains an electrical compartment and a battery compartment. The battery structure is located in the battery compartment and usually consists of rows of battery packs, which typically include multiple battery packs connected in series, parallel, or series-parallel configurations. The electrical compartment houses electrical control components (such as high-voltage boxes and electrical control cabinets).

[0021] The container of an energy storage container refers to a closed or semi-closed structure made of materials such as metal and plastic. It serves as the physical carrier for battery packs, and its design and manufacturing must meet the safety, reliability, and functionality requirements of the battery packs under different usage scenarios. The container provides installation space for the battery packs and, through a reasonable structural design, secures the battery packs within the container, ensuring that the battery packs maintain a relatively stable position during operation and preventing damage or loosening of connections due to vibration, impact, or other factors. The container shape can be cylindrical, cuboid, cube, etc.

[0022] The enclosure uses a direct cooling system for cooling, which utilizes a boiling heat transfer phase change for efficient heat transfer. It employs a high-strength Archimedes flow channel to achieve uniform heat exchange and utilizes cluster-level intelligent automatic flow equalization to achieve balanced heat exchange, effectively improving heat exchange efficiency. The direct cooling system has a fast temperature response, reducing airflow requirements; the fan typically operates quietly, effectively reducing noise and improving energy efficiency. The direct cooling system uses environmentally friendly refrigerant that is not an ODS substance and contains no ethylene glycol liquid, effectively preventing liquid leakage, avoiding short-circuit risks, and improving safety and reliability.

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides an energy storage container system, including a container body 100 and multiple direct cooling devices. A battery compartment 110 is disposed within the container body 100. Within the battery compartment 110, a first battery structure 210, at least one second battery structure 220, and a third battery structure 230 are sequentially spaced along a horizontal first direction. Multiple battery cooling zones are spaced along the bottom of the container body 100 along the horizontal first direction, wherein at least one second battery structure 220 corresponds to two battery cooling zones. Multiple direct cooling devices are spaced along the horizontal first direction on the top of the container body 100, and the direct cooling devices are used to cool the battery structures and / or the battery cooling zones. It should be noted that in this embodiment, the top of the container body 100 refers to the top of the outer side of the container body 100, and the bottom of the container body 100 refers to the bottom of the inner side of the container body 100.

[0024] The energy storage container system provided in this embodiment has at least one second battery structure 220 located in the middle, corresponding to two battery cooling zones. When one battery cooling zone cannot cool the second battery structure 220, the other battery cooling zone can continue to cool the second battery structure 220, maintaining a certain cooling effect. The direct cooling device is located on the top of the outer side of the container 100, avoiding occupying the internal space of the battery compartment 110, improving the space utilization rate of the battery compartment 110, and increasing the energy storage density. In addition, the direct cooling device can cool the battery structure and / or the battery cooling zone, simplifying the overall structure and making assembly easier. The direct cooling device is centrally arranged on the top of the container 100, and the battery cooling zone is centrally arranged on the bottom of the container 100. The functional zoning is clear, avoiding the intersection of pipelines and lines in each area, simplifying the overall structural design and installation process.

[0025] In this embodiment, one direct cooling device is provided for each battery structure. This ensures that each battery structure is individually equipped with a direct cooling device. If one direct cooling device malfunctions, it does not affect the other two direct cooling devices from providing cooling to the corresponding two battery structures, reducing the probability of heat concentration and lowering the risk of thermal runaway.

[0026] Optionally, the first battery structure 210, the second battery structure 220, and the third battery structure 230 each include multiple battery packs 241. Each battery pack 241 includes a first cold plate, and the direct cooling device is connected to the first cold plate of the corresponding battery structure. Each battery pack 241 has an independent first cold plate, which is directly connected to the direct cooling device. This results in a short heat transfer path, low loss, and an independent cooling path, making the temperature of all battery packs 241 more uniform and reducing the risk of capacity decay or thermal runaway caused by temperature differences. In this embodiment, the battery pack 241 typically includes a battery cell composed of multiple battery cells connected in series and / or in parallel, a battery management system (BMS), a thermal management system, an electrical connection system (high-voltage / low-voltage connectors, wiring harnesses, etc.), structural components (casing, brackets, etc.), and protective components.

[0027] In this embodiment, the spacing between adjacent battery cooling areas is d1mm, the spacing between adjacent battery structures is d2mm, and the range of d1 / d2 is 2-6. If the value of d1 / d2 is too large or too small, it will result in low space utilization of the battery compartment 110 and uneven heat dissipation. For example, d1 / d2 can be any value from 2, 2.5, 3.1, 3.2, 3.3, 3.4, 3.6, 3.7, 3.8, 4, or 3-4.

[0028] Optionally, d1mm ranges from 40mm to 60mm; and / or d2mm ranges from 10mm to 20mm. If the value of d1 is too small, the distance between adjacent battery cooling areas will be too small, making it difficult to install pipes within the battery cooling area. If the value of d1 is too large, the excessively wide distance will cause the battery cooling area to occupy too large an area, and a heat dissipation blind zone will be formed between the two battery cooling areas, exacerbating the risk of local overheating. If the value of d2 is too small, the distance between battery structures will be too small. When one battery structure experiences thermal runaway, it will instantly release a high-temperature flame. The small distance will cause the flame to directly spray onto adjacent battery structures, leading to a chain reaction of runaway. In addition, the small distance between battery structures will increase the difficulty of installation. If the value of d2 is too large, it will reduce the space utilization rate of the battery compartment 110, and the area of ​​the battery cooling area needs to be expanded to cover all battery packs, increasing the processing and manufacturing costs. If the distance between adjacent battery structures is too large, the energy density of the battery compartment 110 will be too low. For example, d1mm can be any value among 40mm, 42mm, 44mm, 45mm, 48mm, 50mm, 52mm, 56mm, 60mm or 40mm-60mm, and d2mm can be any value among 10mm, 11mm, 13mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm or 10mm-20mm.

[0029] Optionally, the second battery structure 220 is provided with one battery cooling region, which includes a first cooling region 310 and a second cooling region 320 arranged along a first horizontal direction. The first cooling region 310 corresponds to a portion of the first battery structure 210 and the second battery structure 220, and the second cooling region 320 corresponds to the third battery structure 230 and the remaining portion of the second battery structure 220. During the cooling process, when the second direct cooling device 420 fails to cool, the first cooling region 310 can cool a portion of the second battery structure 220, ensuring a certain cooling effect on the middle part of the second battery structure 220 and reducing the risk of thermal runaway. When the first direct cooling device 410 fails to cool, the second cooling region 320 can cool the remaining portion of the second battery structure 220, ensuring a certain cooling effect on the middle part of the second battery structure 220 and reducing the risk of thermal runaway.

[0030] In this embodiment, the second battery structure 220 includes two battery pack rows spaced apart along a horizontal first direction. One battery pack row corresponds to the first cooling region 310, and the other battery pack row corresponds to the second cooling region 320. Exemplarily, during the cooling process, when the second direct cooling device 420 fails to cool, the first cooling region 310 can continue to cool one of the battery pack rows of the second battery structure 220, ensuring a certain cooling effect on the middle section of the second battery structure 220 and reducing the risk of thermal runaway. When the first direct cooling device 410 fails to cool, the second cooling region 320 can continue to cool the other battery pack row of the second battery structure 220, ensuring a certain cooling effect on the middle section of the second battery structure 220 and reducing the risk of thermal runaway. In this embodiment, the battery pack rows include multiple battery packs 241 stacked vertically.

[0031] Preferably, one direct cooling device corresponds to cooling one battery cooling area. This ensures that each battery cooling area is individually assigned to a direct cooling device. If one direct cooling device malfunctions, the remaining direct cooling devices will not affect the cooling provided to the corresponding battery cooling area, reducing the probability of heat concentration and mitigating the risk of thermal runaway. In this embodiment, the direct cooling device includes a first direct cooling device 410 and a second direct cooling device 420 arranged along a horizontal first direction. The first direct cooling device 410 cools the first cooling area 310, and the second direct cooling device 420 cools the second cooling area 320. That is, the first direct cooling device 410 provides cooling exclusively to the first cooling area 310, and the second direct cooling device 420 provides cooling exclusively to the second cooling area 320.

[0032] Optionally, the spacing between adjacent direct cooling units is d3mm, and the range of d1 / d3 is 0.2-0.75. If the value of d1 / d3 is too large, the spacing between adjacent direct cooling units will be too small, resulting in overlapping cooling coverage areas. This will lead to excessively low temperatures in the empty spaces between adjacent cooling zones, wasting cooling capacity and potentially exacerbating energy consumption of the battery pack 241 in low-temperature environments. Furthermore, if the spacing between adjacent direct cooling units is too small, the units will be densely packed, causing pipes to squeeze against each other, which can easily lead to misalignment of interfaces during installation. If the value of d1 / d3 is too small, the spacing between adjacent direct cooling units will be too large, preventing the cooling coverage radius from being fully connected. This will create heat dissipation blind spots in the dense cooling areas, causing continuous heat accumulation in the corresponding battery pack rows, which can easily trigger thermal runaway. For example, d1 / d3 can be any value from 0.2, 0.4, 0.5, 0.6, 0.7, 0.75, or 0.2-0.75.

[0033] Optionally, d3 can range from 80mm to 200mm. If the value of d3 is too small, the cooling coverage of adjacent direct cooling devices will overlap, resulting in excessively low temperatures in the overlapping areas. To avoid overcooling, the battery pack 241 will need to frequently start and stop the direct cooling devices or reduce its output power, leading to low heat exchange efficiency and complex assembly. If the value of d3 is too large, the cooling coverage radius of a single direct cooling device will be limited, and the coverage areas of adjacent direct cooling devices will not be able to connect. The intermediate area will not receive effective cooling, causing heat to accumulate continuously, potentially exceeding the safety threshold and triggering thermal runaway. For example, d3mm can be any value among 80mm, 90mm, 100mm, 115mm, 130mm, 160mm, 175mm, 200mm, or 80mm-200mm.

[0034] Optionally, the projected area of ​​the direct cooling device in the battery cooling area is s3mm. 2 The total area of ​​the battery cooling region is s4mm. 2 The range of s3 / s4 is 0.4-0.9. If the value of s3 / s4 is too large, the direct cooling device will output excessive cooling capacity, which cannot be effectively utilized, leading to increased system energy consumption. At the same time, the material and hardware costs of the direct cooling device will increase significantly, and the installation complexity will increase. If the value of s3 / s4 is too small, the heat dissipation efficiency of the battery compartment 110 will be low, the temperature difference between the projected and unprojected areas in the cooling area will be large, and the battery structure in different cooling areas will exhibit uneven charging and discharging rates, accelerating capacity decay and shortening the overall lifespan of the system. For example, s3 / s4 can be any value among 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 0.4-0.9.

[0035] Optionally, s3mm 2 The range is 6mm 2 -9.5mm 2 ; and / or, s4mm 2 The range is 11mm 2 -15mm 2If the value of s3 is too small, the effective range of the direct cooling device cannot cover the entire cooling area. Areas not covered by the direct cooling device cannot obtain effective cooling, and the temperature of the battery structure may quickly exceed the safety threshold, triggering a thermal runaway chain reaction. If the value of s3 is too large, the effective range of the direct cooling device far exceeds the actual cooling requirements, increasing energy consumption and manufacturing costs. If the value of s4 is too small, the heat dissipation capacity of the battery compartment 110 is severely insufficient, and heat cannot be dissipated in time, easily leading to a thermal runaway chain reaction. Furthermore, a small value of s4 will cause heat dissipation resources to concentrate in the core area, creating heat dissipation dead zones at the edges and corners of the battery structure, which become the trigger points for thermal runaway. If the value of s4 is too large, the overall battery cooling area occupies a large amount of space, resulting in excessive energy consumption, high manufacturing costs, and increased installation complexity. For example, s3mm 2 It can be 6mm or 6.5mm. 2 7mm 2 7.5mm 2 8mm 2 8.64mm 2 9mm 2 9.5mm 2 Or 6mm 2 -9.5mm 2 Any value in s4mm 2 It can be 11mm 2 11.5mm 2 12mm 2 12.88mm 2 13mm 2 13.5mm 2 14mm 2 15mm 2 Or 11mm 2 -15mm 2 Any one of the values ​​in.

[0036] Optionally, the battery cooling area includes a second cold plate 700, and the direct cooling device is connected to the corresponding second cold plate 700 of the battery cooling area. The cooling area formed by the second cold plate 700 achieves heat transfer through direct contact heat transfer, effectively improving heat transfer efficiency. In this embodiment, the first cooling area 310, the second cooling area 320, and the third cooling area 330 are all formed by a single second cold plate 700. In other embodiments, the size of the second cold plate 700 can be set according to the size of each cooling area to meet the requirements.

[0037] In this embodiment, each battery structure includes two battery pack rows spaced apart along a horizontal first direction. Multiple partitions 111, also spaced apart along the horizontal first direction, are disposed within the battery compartment 110. These partitions divide the battery compartment 110 into multiple battery cavities, each housing a battery pack row. This ensures that each battery pack row has an independent mounting cavity, and the output return pipes 600 of each battery pack row are concentrated within their own cavity, avoiding cross-alignment and simplifying the installation process. The partitions 111 form a support structure within the battery compartment 110, enhancing the torsional and compressive strength of the battery compartment 110, reducing deformation of the housing 100, and thus preventing the battery pack rows from being damaged by compression.

[0038] Optionally, an electrical compartment 120 is provided inside the container 100. The energy storage container system also includes an electrical cooling area, which is located corresponding to the electrical compartment 120, and at least one direct cooling device is used to cool the electrical cooling area. The direct cooling device can provide cooling for the battery structure, the battery cooling area, and the electrical cooling area. Compared with the existing composite temperature control structure using "liquid cooling + air conditioning", this simplifies the overall structure of the temperature control system and improves assembly efficiency.

[0039] In this embodiment, the area of ​​the battery cooling region is s1mm. 2 The area of ​​the electrical cooling zone is s2mm. 2 The range of s1 / s2 is 3.75-15. If the value of s1 / s2 is too large, when the electrical compartment 120 is operating at full load or the ambient temperature is too high, the cooling effect will be poor due to the small electrical cooling area, leading to the temperature of components such as the main control module exceeding the standard, causing faults such as electric shock oxidation. In addition, the battery cooling area outputs more cooling capacity, and the excess heat dissipation area may cause the temperature of the battery structure in the battery compartment 110 to be too low, indirectly increasing the system energy consumption. If the value of s1 / s2 is too small, the heat of the battery structure under high load cannot be dissipated in time, which can easily lead to the continuous rise in the temperature of the battery structure and trigger thermal runaway. For example, s1 / s2 can be any value among 3.75, 5.5, 7.5, 9.5, 11.5, 13.5, 15 or 3.5-15.

[0040] Optionally, s1mm 2 The range is 1.5mm. 2 -3.0mm 2 The preferred value is 2.204m 2 ; and / or, s2mm 2 The range is 0.2mm. 2 -0.4mm 2 The preferred value is 0.31m. 2If the value of s1 is too small, the cooling area of ​​the battery cooling zone will be too small, and the heat in the battery compartment 110 cannot be dissipated in time. The battery structure will be in a high-temperature environment for a long time, the internal electrolyte will decompose faster, the active material structure will be damaged, the performance will degrade rapidly, and a thermal runaway chain reaction will be easily triggered. If the value of s1 is too large, the battery cooling zone will occupy a large amount of space at the bottom of the battery compartment 110, increasing processing costs and maintenance workload. If the value of s2 is too small, the cooling effect in the electrical compartment 120 will be poor, and the high-voltage box 500 and electrical control cabinet will be prone to accelerated aging due to heat accumulation, shortening their service life. The high-voltage box 500 and electrical control cabinet may overheat and catch fire due to heat accumulation, and the flames may spread to the battery compartment 110 through the wiring, indirectly inducing thermal runaway. If the value of s2 is too large, the direct cooling device will be in a low-load operation state for a long time, resulting in energy waste, and the electrical cooling zone area will be too large, increasing manufacturing costs and maintenance workload. For example, s1mm 2 It can be 1.5mm 2 1.7mm 2 1.9mm 2 2.204mm 2 2.3mm 2 2.4mm 2 2.8mm 2 3.0mm 2 Or 1.5mm 2 -3.0mm 2 Any value in s2mm 2 It can be 0.2mm 2 0.22mm 2 0.24mm 2 0.26mm 2 0.3mm 2 0.31mm 2 0.36mm 2 0.4mm 2 or 0.2mm 2 -0.4mm 2 Any one of the values ​​in.

[0041] In this embodiment, the electrical cooling area includes a third cooling area 330, which corresponds to the electrical compartment 120, and a third direct cooling device 430 corresponds to the third cooling area 330. A separate third cooling area 330 is provided within the electrical compartment 120, and the third direct cooling device 430 corresponds to the third cooling area 330. When the first direct cooling device 410 and the second direct cooling device 420 malfunction, the third direct cooling device 430 does not affect the cooling capacity provided to the third cooling area 330, ensuring the cooling effect of the electrical compartment 120 and preventing thermal runaway in the electrical compartment 120.

[0042] Furthermore, the third direct cooling device 430 is also used to cool the third battery structure 230. This improves the utilization rate of the third direct cooling device 430, while simplifying the overall structure and improving assembly convenience.

[0043] Optionally, the battery compartment 110 and the electrical compartment 120 are spaced apart along a first horizontal direction, and the three battery structures are also spaced apart along the first horizontal direction. The electrical compartment 120 houses a high-voltage box 500 and an electrical control cabinet spaced apart along a second horizontal direction, with the first and second horizontal directions perpendicular to each other. This arrangement effectively improves space utilization and avoids wasted space.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
