Description

Technical Field

[0001] This utility model relates to a battery rack, and more particularly to a modular battery rack for energy storage containers. Background Technology

[0002] Energy storage containers are systems that combine energy storage and power supply. They have functions such as smooth transition, peak shaving and valley filling, frequency regulation and voltage regulation. They can enable smooth output of solar and wind power generation, reducing the impact of randomness, intermittency and fluctuation on the power grid and users. By charging during off-peak hours and discharging during peak hours, users' electricity expenses can be reduced. They can operate independently when the main power grid is down, ensuring uninterrupted power supply to users.

[0003] Existing battery racks rely on manual adjustment when installing battery modules, which is time-consuming and labor-intensive. The lack of a rear-end fixing structure can easily cause the modules to shake. Uneven airflow distribution between battery clusters can lead to localized overheating, affecting battery life. In addition, battery racks are difficult to disassemble and assemble, and transportation requires large equipment, resulting in high production and transportation costs. Utility Model Content

Detailed Implementation

[0034] like Figure 1 , 2 As shown, this utility model discloses a modular battery rack for an energy storage container, including a battery compartment 01 for holding battery packs, a connecting mechanism 03, and a high-voltage box compartment 02 for holding high-voltage boxes. There are multiple battery compartments 01 arranged vertically in layers. Two adjacent battery compartments 01 are connected by the connecting mechanism 03. The high-voltage box compartment 02 is located below the bottom battery compartment 01 and is connected to the battery compartment 01 by the connecting mechanism 03.

[0035] The modular battery rack is equipped with a battery compartment 01 module and a high-voltage box module. The battery packs are installed in the battery compartment 01, and the high-voltage box is installed in the high-voltage box compartment 02. The number of battery compartments 01 can be flexibly adjusted according to actual needs, such as increasing or decreasing them in the vertical direction. A high-voltage box compartment 02 is installed below the bottom battery compartment 01, and the battery packs in the battery compartment 01 are uniformly controlled through a single high-voltage box. In addition, multiple rows of modular battery racks can be set according to the structure of the energy storage container. Each row of battery packs is equipped with a high-voltage box for controlling the battery packs in that row. This setting can not only effectively meet the energy storage needs of the energy storage container and improve its flexibility, but also enhance its safety and prevent safety accidents caused by high-voltage box overload.

[0036] In terms of connection, the two adjacent battery compartments 01 and the battery compartment 01 and the high voltage box compartment 02 are firmly fixed by the connection mechanism 03. The modular battery rack isolates and supports the battery pack and the high voltage box, thereby ensuring the robustness and stability of the modular battery rack.

[0037] In actual use, the arrangement is carried out according to the structure of the energy storage container and the energy storage requirements. First, multiple battery compartments 01 are connected in sequence through the connecting mechanism 03. Then, the high-voltage box compartment 02 is connected to the bottom battery compartment 01 through the connecting mechanism 03. After that, the assembled modular battery rack is placed into the energy storage container and firmly fixed by bolts or locking pins. Finally, the battery pack and high-voltage box are installed in the corresponding battery compartment 01 and high-voltage box compartment 02 respectively, completing the arrangement of the energy storage container.

[0038] like Figure 1 , 4 As shown in Figure 5, the battery compartment 01 includes multiple vertically arranged support columns 11, a left crossbeam 12, a right crossbeam 13, and heat dissipation guide rails 14. The multiple support columns are divided into left support columns 11 and right support columns 11. The number of support columns 11 on the left and right sides is the same and there are at least two of them on each side. The left crossbeam 12 is connected to the left support column 11, and the right crossbeam 13 is connected to the right support column 11. The left crossbeam 12 and the right crossbeam 13 are at the same height and are arranged in a mirror symmetrical manner with respect to the vertical central axis of the battery compartment 01. There are at least two heat dissipation guide rails 14, which are connected to the left crossbeam 12 and the right crossbeam 13 respectively.

[0039] There are at least two support columns 11 on each side of the battery compartment 01, which are used to form a stable support structure and connect with other parts. Here, we will take six support columns 11 as an example to illustrate the modular battery rack. All six support columns 11 are placed vertically. The left crossbeam 12 is horizontally welded to the three support columns 11 on the left side. The left crossbeam 12 is horizontally welded to the three support columns 11 on the left side. The right crossbeam 13 is horizontally welded to the three support columns 11 on the right side. Both crossbeams are set close to the lower end of the support columns 11. This design ensures that the battery compartment 01 has sufficient height to accommodate different types of battery packs.

[0040] The left crossbeam 12 and the right crossbeam 13 are L-shaped guide rails 27. The L-shaped guide rails 27 have a double-sided beam structure that is perpendicular to each other. The lower side beam and the side side beam have a dual function. The lower side beam can not only support the battery pack, but also connect to the heat dissipation guide rail 14. The side side beam can limit the position of the battery pack, and due to its large cross-sectional area, it can also connect to the support column 11.

[0041] like Figure 5 and Figure 11 As shown, the heat dissipation guide rail 14 is provided with several heat dissipation holes 141. The heat dissipation guide rail 14 dissipates heat from the battery pack placed in the battery compartment 01 through the heat dissipation holes 141, and the heat generated by the battery pack can be discharged through the heat dissipation holes 141. The heat dissipation guide rail 14 is used to connect the left crossbeam 12 and the right crossbeam 13, thereby forming the structure of the battery compartment 01 and enhancing its stability.

[0042] To control costs, at least two heat dissipation rails 14 are provided, working in conjunction with the left crossbeam 12 and the right crossbeam 13 to form the battery compartment 01 structure. Here, the battery compartment 01 is illustrated using three heat dissipation rails 14 as an example. The two ends of the three heat dissipation rails 14 are welded to the left crossbeam 12 and the right crossbeam 13 respectively, and are perpendicular to the two crossbeams, forming a robust and stable rectangular structure. Furthermore, the three heat dissipation rails 14 correspond to the three support columns 11 on the left and right sides of the battery compartment 01. When the battery compartment 01 is subjected to lateral forces in the left and right directions, the heat dissipation rails 14 and the support columns 11 are subjected to forces in the same direction and on the same axis, effectively preventing the battery compartment 01 from twisting, thereby enhancing its stability. In addition, more heat dissipation rails 14 can be added as needed to further improve the heat dissipation and robustness of the battery compartment 01.

[0043] like Figure 6 , 7As shown in Figure 8, the upper end of the support column 11 is provided with a first connecting groove 111 and a first connecting hole 113, with the first connecting hole 113 extending laterally through the first connecting groove 111. The lower end of the support column 11 is provided with a second connecting groove 112 and a second connecting hole 114, with the second connecting hole 114 extending laterally through the second connecting groove 112. The connecting mechanism 03 includes a connecting rod 31 and a fastener 32 corresponding to the support column 11. The upper and lower ends of the connecting rod 31 are respectively provided with a third connecting hole 311 and a fourth connecting hole 312 extending laterally through itself. The upper and lower ends of the connecting rod 31 are respectively inserted into the second connecting groove 112 and the first connecting groove 111 of the support column 11 of the two adjacent battery compartments 01. The fasteners 32 are respectively inserted into the aligned first connecting hole 113 and the fourth connecting hole 312, as well as the second connecting hole 114 and the third connecting hole 311, to securely connect the two adjacent battery compartments 01.

[0044] The first connecting groove 111 and the second connecting groove 112 are located inside the upper and lower ends of the support column 11 and both extend vertically, facilitating the insertion of the connecting rod 31 into the grooves to achieve a firm connection between the two adjacent battery compartments 01. Simultaneously, the first connecting hole 113 and the second connecting hole 114 extend laterally through the first connecting groove 111 and the second connecting groove 112, respectively, and can cooperate with the fourth and third through holes extending laterally through the upper and lower ends of the connecting rod 31. With the fastener 32 inserted into the aligned connecting holes, the stability and firmness of the connection between the battery compartments 01 are further enhanced.

[0045] like Figure 8 As shown, fastener 32 is a bolt, wherein the screw adopts GB5783 screw, and a flat washer and a spring washer are fitted on the bolt. The flat washer adopts GB97.1 flat washer, and the spring washer adopts GB93 spring washer. The nut adopts GB6170 nut. After the support column 11 between two adjacent battery compartments 01 is connected by the connecting rod 31, a flat washer is fitted on the lower end of the screw, and the screw is inserted into the aligned through hole. Then, a flat washer and a spring washer are fitted on the upper end of the screw in sequence. Finally, the nuts are tightened to firmly fix the two battery compartments 01. The bolt adopts a connection method of two flat washers, one spring washer and one nut, which has the following advantages:

[0046] (1) Excellent anti-loosening performance: The function of the spring washer is to provide elastic force. After the bolt connection is tightened, the spring washer is compressed and generates a rebound force. This rebound force can continue to act between the nut and the connector, preventing the nut from loosening due to equipment vibration, impact and other reasons.

[0047] (2) Uniform Load Distribution: Two flat washers can better distribute the load evenly in a bolted connection. When the bolt is tightened, the force is transmitted to the connector through the flat washer. The flat washer can disperse the concentrated bolt tension over a larger area, making the stress on each part of the connector more uniform. This helps to improve the load-bearing capacity of the connector and reduce the risk of damage caused by excessive local stress. Especially in connection parts subjected to large loads, the connection method of two flat washers, one spring washer, and one nut can play a more effective role.

[0048] The specific steps during assembly are as follows:

[0049] 1. First, insert the upper end of the connecting rod 31 into the second connecting groove 112 of a certain support column 11 of the upper battery compartment 01. At this time, ensure that the second connecting hole 114 and the third connecting hole 311 are precisely aligned. Then, insert the screw into the aligned second connecting hole 114 and the third connecting hole 311 and fix it with a nut.

[0050] 2. Next, insert the lower end of the connecting rod 31 into the first connecting groove 111 of the support column 11 of the lower battery compartment 01 corresponding to the upper battery compartment 01. Similarly, ensure that the first connecting hole 113 is aligned with the fourth connecting hole 312. Then, insert the screw into the first connecting hole 113 and the fourth connecting hole 312 and fix it with a nut.

[0051] Each battery compartment 01 is equipped with a connecting mechanism 03 on its support column 11. That is, the support columns 11 of two adjacent battery compartments 01 are connected and fixed by connecting rods 31 and fasteners 32 to ensure the stability and firmness of the connection between battery compartments 01.

[0052] This configuration allows for flexible adjustment of the number of battery compartments 01 according to energy storage needs. Furthermore, the battery compartments 01 are all detachably connected, which not only meets different energy storage requirements but also facilitates transportation and installation.

[0053] like Figure 1 , 2 As shown, limit blocks 121 are provided on both the left crossbeam 12 and the right crossbeam 13. Liquid cooling holes 122 are provided on both the left crossbeam 12 and the right crossbeam 13.

[0054] Limiting blocks 121 are welded to the rear sides of both the left crossbeam 12 and the right crossbeam 13. These limiting blocks 121 restrict the battery pack and prevent it from sliding off the rear of the battery compartment 01. The left crossbeam 12 and right crossbeam 13, which use L-shaped guide rails 27, can limit the battery pack in the left and right directions. The limiting blocks 121 can limit the rear of the battery pack, while the front serves as the loading and unloading port for the battery pack. This configuration ensures that the battery pack operates stably in the battery compartment 01.

[0055] like Figure 4 As shown, the energy storage container is equipped with a liquid cooling module (not shown in the figure) to cool the battery pack. The liquid cooler is connected to the battery pack through liquid cooling pipes. To ensure the firmness of the connection between the liquid cooling pipes and the battery pack, and to maintain the cleanliness of the interior of the energy storage container, multiple liquid cooling holes 122 for fixing the liquid cooling pipes are provided on the left crossbeam 12 and the right crossbeam 13.

[0056] During installation, the liquid cooling pipes are first inserted into the liquid cooling holes 122 on each battery compartment 01, and then connected to the battery pack. The liquid cooling pipes are fixed through the liquid cooling holes 122, so that the liquid cooling pipes of each battery compartment 01 in the energy storage container are distributed in an orderly manner. This design not only makes the overall layout more beautiful, but also avoids friction between the liquid cooling pipes and other components, thereby extending the service life of the liquid cooling pipes.

[0057] like Figure 1 , 2 As shown in Figure 3, the high-voltage box compartment 02 includes high-voltage box support columns 21, front crossbeam 22, middle crossbeam 23, rear crossbeam 24, left binding beam 25, and right binding beam 26, which are structurally identical to and correspond one-to-one with the support columns 11 of the battery compartment 01. The front crossbeam 22 and rear crossbeam 24 are respectively mounted on two high-voltage box support columns 21 on the front and rear sides of the high-voltage box compartment 02. The left binding beam 25 and right binding beam 26 are respectively mounted on the front crossbeam 22 and rear crossbeam 24. The middle crossbeam 23 is mounted on the left binding beam 25 and right binding beam 26. The connection method between the high-voltage box compartment 02 and the battery compartment 01 is the same as the connection method between two adjacent battery compartments 01. Multiple binding holes 251 are provided on both the left binding beam 25 and the right binding beam 26.

[0058] The high-voltage box support column 21 has the same structure as the support column 11 of the battery compartment 01. It is also provided with a first connecting groove 111, a second connecting groove 112, a first connecting hole 113 and a second connecting hole 114. The number of high-voltage box support columns 21 is the same as the number of support columns 11 of the battery compartment 01 and they correspond one-to-one. For ease of explanation, six high-voltage box support columns 21 will be used as an example.

[0059] The high-voltage box support columns 21 are all placed vertically. The front crossbeam 22 and the rear crossbeam 24 are welded to the two high-voltage box support columns 21 on the front and rear sides respectively. The front and rear crossbeams are at the same height and perpendicular to the high-voltage box support columns 21. The left binding beam 25 and the right binding beam 26 are used to fix the cables. The binding wires are passed through the binding holes 251 to fix the cables of the high-voltage box and battery pack to the two binding beams. The two ends of the left and right binding beams are welded to the front crossbeam 22 and the rear crossbeam 24 respectively and are perpendicular to the front and rear crossbeams. This forms the bottom of the rectangular high-voltage box compartment 02, ensuring that the high-voltage box compartment 02 has sufficient load-bearing capacity.

[0060] The middle crossbeam 23 is welded to the left binding beam 25 and the right binding beam 26. Since this example uses six high-voltage box support columns 21, both ends of the middle crossbeam 23 are welded to the two middle high-voltage box support columns 21 on the left and right sides, respectively, maintaining the same height as the front crossbeam 22 and the rear crossbeam 24, facilitating stable placement of the high-voltage boxes. The front, middle, and rear crossbeams are all positioned close to the lower end of the high-voltage box support columns 21. This design ensures sufficient height inside the high-voltage box compartment 02 to accommodate different types of high-voltage boxes, thus forming the structure of the high-voltage box compartment 02.

[0061] The high-voltage box compartment 02 and the battery compartment 01 are connected by a connecting mechanism 03, which is exactly the same as the connection method between two adjacent battery compartments 01. The connecting rod 31 is inserted into the connecting grooves of the corresponding high-voltage box support column 21 and battery compartment 01 support column 11 of the high-voltage box compartment 02 and the battery compartment 01, then the screw is inserted into the aligned connecting hole, and finally the nut is used to fix it, thereby firmly connecting the battery compartment 01 and the high-voltage box compartment 02 to form a modular battery rack structure.

[0062] During assembly, first place the high-voltage box compartment 02 at the bottom, then connect a battery compartment 01 to the top of the high-voltage box compartment 02. After that, according to the energy storage requirements and the structure of the energy storage container, a certain number of battery compartments 01 can be installed from bottom to top. Alternatively, multiple sets of modular battery racks can be arranged side by side. Finally, the assembled modular battery racks are fixed inside the energy storage container.

[0063] like Figure 3 As shown, the high-voltage box compartment 02 also includes guide rails 27 with both ends respectively disposed on the front crossbeam 22 and the middle crossbeam 23, and at least two guide rails 27 are provided. The high-voltage box compartment 02 also includes a front baffle 28 and a rear baffle 29. Both the front crossbeam 22 and the middle crossbeam 23 are provided with multiple slots 221, and both the front baffle 28 and the rear baffle 29 are provided with protrusions 281 that are adapted to the slots 221. The front baffle 28 and the rear baffle 29 are respectively inserted into the slots 221 on the front crossbeam 22 and the middle crossbeam 23 through their own protrusions 281.

[0064] The guide rail 27 is welded to the front crossbeam 22 and the middle crossbeam 23 at both ends. Depending on the requirements, the guide rail 27 can also be welded between the middle crossbeam 23 and the rear crossbeam 24. The guide rail 27 can not only support the high-voltage box, but also enhance the stability of the high-voltage box compartment 02, thereby meeting the placement requirements of different high-voltage boxes.

[0065] like Figure 9 , 10As shown, multiple slots 221 are provided on the front, middle and rear crossbeams. The front baffle 28 and the rear baffle 29 are provided with protrusions 281 that are adapted to the slots 221. The front baffle 28 is inserted into the slots 221 of the front crossbeam 22 through the protrusions 281. The rear baffle 29 can be inserted into the middle crossbeam 23 or the rear crossbeam 24 according to actual needs. The front baffle 28 and the rear baffle 29 limit the high-voltage box in the front and rear directions, thereby preventing the high-voltage box from slipping out of the high-voltage chamber.

[0066] One front baffle 28 is provided on each of the left and right sides of the high-voltage box compartment 02, leaving space in the middle for operating the high-voltage box. Two or more rear baffles 29 can also be provided as needed to achieve all-round shielding of the rear of the high-voltage box and ensure stable operation of the high voltage in the high-voltage box compartment 02.
