Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a prefabricated battery pack compartment and an energy storage container. Background Technology

[0002] In the field of energy storage, containerized energy storage systems are widely used due to their flexibility and scalability. As the core component of an energy storage system, the battery pack typically needs to be assembled and installed inside a container. The traditional assembly method involves installing each battery pack individually onto a battery rack inside the container, and then connecting power lines, communication lines, and piping for liquid cooling and fire suppression one by one after installation.

[0003] Currently, the assembly process for battery pack units within energy storage containers used by OEMs is quite complex and labor-intensive. Due to space constraints within the container, each battery pack needs to be lifted to the appropriate height and pushed in and secured, a process that is not only time-consuming and labor-intensive but also prone to errors. Furthermore, after the battery packs are installed, OEMs also need to connect the power, communication lines, liquid cooling, and fire-fighting plugs between each battery pack, further increasing the complexity of the assembly and the probability of errors.

[0036] Compared to the aforementioned background technology, the prefabricated battery pack compartment provided in this application mainly includes a compartment body, a high-voltage distribution box, a battery pack, a secondary water inlet pipe assembly, and a secondary water outlet pipe assembly. The compartment body has a first cavity and a second cavity; the high-voltage distribution box is located in the first cavity; the battery pack is located in the second cavity and is electrically connected to the high-voltage distribution box; the secondary water inlet pipe assembly is located in the compartment body and is connected to the liquid cooling inlet of the battery pack, and the secondary water inlet pipe assembly has a secondary water inlet connector; the secondary water outlet pipe assembly is located in the compartment body and is connected to the liquid cooling outlet of the battery pack, and the secondary water outlet pipe assembly has a secondary water outlet connector; when the prefabricated battery pack compartment is loaded into a container, the high-voltage distribution box is electrically connected to the power line of the container, the secondary water inlet connector is connected to the primary water inlet pipe of the container, and the secondary water outlet connector is connected to the primary return water pipe of the container.

[0037] In existing technologies, the battery pack installation process inside energy storage containers presents numerous challenges. Traditional assembly methods require installing each battery pack individually within the container and then connecting the power lines, liquid cooling pipes, and other piping between the packs one by one after installation. This process is not only time-consuming and labor-intensive but also prone to connection errors due to limited operating space, increasing the complexity and probability of errors in the assembly process.

[0038] To address the aforementioned issues, this application provides a prefabricated battery pack compartment. The core design element integrates a high-voltage distribution box, battery pack, and cooling pipes within a single prefabricated compartment, with internal connections between these components pre-completed. Specifically, the prefabricated compartment is divided into a first cavity and a second cavity. The high-voltage distribution box is installed in the first cavity, while the battery pack is installed in the second cavity and electrically connected to the high-voltage distribution box. Furthermore, a secondary water inlet pipe assembly and a secondary water outlet pipe assembly are connected to the liquid cooling inlet and outlet of the battery pack, respectively, and secondary water inlet and outlet connectors are provided on the pipe assemblies.

[0039] This integrated design allows the prefabricated battery pack compartment to be electrically connected to the container's power line only when loaded into the container, and the secondary water inlet and outlet connectors to be connected to the container's primary water inlet and return pipes, respectively. This avoids the cumbersome process of installing and connecting battery packs and related pipes individually inside the container, significantly improving assembly efficiency.

[0063] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the battery pack prefabrication compartment provided in an embodiment of this application. Figure 2 A schematic diagram of the battery pack prefabrication compartment and the primary return water pipeline provided in the embodiments of this application.

[0066] In a first specific embodiment, the battery pack prefabricated compartment 100 provided in this application mainly includes a compartment 1, a high-voltage distribution box 2, a battery pack 3, a secondary water inlet pipe assembly 4, and a secondary water outlet pipe assembly 5. The compartment 1 is provided with a first cavity 101 and a second cavity 102; the high-voltage distribution box 2 is located in the first cavity 101; the battery pack 3 is located in the second cavity 102 and is electrically connected to the high-voltage distribution box 2; the secondary water inlet pipe assembly 4 is located in the compartment 1 and is connected to the liquid cooling inlet 301 of the battery pack 3, and is provided with a secondary water inlet connector 401; the secondary water outlet pipe assembly 5 is located in the compartment 1 and is connected to the liquid cooling outlet 302 of the battery pack 3, and is provided with a secondary water outlet connector 501.

[0067] When the prefabricated battery pack compartment 100 is loaded into the container, the high-voltage distribution box 2 is electrically connected to the power line of the container, the secondary water inlet connector 401 is connected to the primary water inlet pipe 200 of the container, and the secondary water outlet connector 501 is connected to the primary water return pipe 300 of the container.

[0068] In existing technologies, the battery pack installation process inside energy storage containers presents numerous challenges. Traditional assembly methods require installing each battery pack individually within the container and then connecting the power lines, liquid cooling pipes, and other piping between the packs one by one after installation. This process is not only time-consuming and labor-intensive but also prone to connection errors due to limited operating space, increasing the complexity and probability of errors in the assembly process.

[0069] To address the aforementioned issues, this application provides a prefabricated battery pack compartment 100. The core design element integrates the high-voltage distribution box 2, the battery pack 3, and the cooling pipes within a single prefabricated compartment, with the internal connections between these components pre-completed. Specifically, the compartment 1 is divided into a first cavity 101 and a second cavity 102. The high-voltage distribution box 2 is installed in the first cavity 101, while the battery pack 3 is installed in the second cavity 102 and connected to the high-voltage distribution box 2 via electrical connections. Furthermore, a secondary water inlet pipe assembly 4 and a secondary water outlet pipe assembly 5 are respectively connected to the liquid cooling inlet 301 and liquid cooling outlet 302 of the battery pack 3, and a secondary water inlet connector 401 and a secondary water outlet connector 501 are provided on the pipe assemblies.

[0070] This integrated design allows the prefabricated battery pack compartment 100 to be installed into the container simply by connecting the high-voltage distribution box 2 to the container's power line, and connecting the secondary water inlet connector 401 and the secondary water outlet connector 501 to the container's primary water inlet pipe 200 and primary water return pipe 300, respectively. This avoids the cumbersome process of installing and connecting battery packs and related pipes individually inside the container, significantly improving assembly efficiency. Furthermore, since the internal connections are completed within the prefabricated compartment, the complexity of on-site operations and the possibility of errors are reduced, thus lowering the risk of failure.

[0071] Based on the above structural and process descriptions, it can be seen that the prefabricated battery pack compartment 100 has at least the following beneficial effects: By integrating the high-voltage distribution box 2, the battery pack 3, and the cooling pipes into the prefabricated compartment, the internal connections are completed in advance, avoiding the cumbersome process of installing and connecting the battery packs and related pipes one by one in the container in the prior art, thereby significantly improving assembly efficiency and reducing the risk of errors.

[0072] It should be noted that, apart from the above description, this embodiment does not limit the ratio of high-voltage distribution box 2 to battery pack 3. For example, one high-voltage distribution box 2 can be combined with multiple battery packs 3 to form a one-to-many configuration relationship, and the number of battery packs 3 can be arbitrarily selected according to actual needs, without being limited by a specific number.

[0073] Meanwhile, this embodiment does not limit the electrical connection method between the high-voltage distribution box 2 and the battery pack 3, or between the battery packs 3 and each other. It can be connected in series or in parallel, or other suitable connection methods can be selected according to the specific application scenario and system design requirements to meet different electrical performance requirements.

[0074] Furthermore, this embodiment does not limit the number of groups formed by combining high-voltage distribution boxes 2 and battery packs 3. Using the number of high-voltage distribution boxes 2 as a representative example, it can be a cluster formed by one high-voltage distribution box 2 and at least one battery pack 3, or multiple clusters formed by multiple high-voltage distribution boxes 2 each being grouped with at least one battery pack 3, thereby achieving flexible system configuration and expansion. All of the above situations should fall within the scope of this embodiment.

[0075] Please refer to Figures 3 to 5 ,in, Figure 3 This is a schematic diagram of the battery pack prefabrication compartment and the primary gas dissipation pipeline provided in an embodiment of this application. Figure 4 This is an exploded view of the cabin provided in an embodiment of this application. Figure 5 An exploded view of the cabin provided in an embodiment of this application from another perspective.

[0076] In some embodiments, the prefabricated battery pack compartment 100 further includes: a secondary fire-fighting pipeline assembly 6, disposed in the compartment 1, the secondary fire-fighting pipeline assembly 6 having a secondary fire-fighting connector 601; when the prefabricated battery pack compartment 100 is loaded into a container, the secondary fire-fighting connector 601 is connected to the primary fire-fighting pipeline 400 of the container.

[0077] In this embodiment, the prefabricated battery pack compartment 100 not only includes a secondary inlet water pipe assembly 4 and a secondary outlet water pipe assembly 5 for liquid cooling, but also further incorporates a secondary fire-fighting pipe assembly 6. This enhances the safety performance of the prefabricated compartment while fulfilling basic cooling functions. The secondary fire-fighting pipe assembly 6 is located within the compartment 1, and its structural design is similar to that of the liquid cooling pipe assembly, both designed to achieve specific functional connections. The secondary fire-fighting pipe assembly 6 is equipped with a secondary fire-fighting connector 601. This design allows for rapid connection between the prefabricated battery pack compartment 100 and the container's primary fire-fighting pipe 400 when the prefabricated battery pack compartment 100 is loaded into the container, ensuring the integrity and effectiveness of the fire-fighting system.

[0078] The advantage of this design lies in the fact that the secondary fire-fighting piping assembly 6, like the liquid-cooled piping assembly, is prefabricated. This means that during the production of the battery pack prefabrication compartment 100, the fire-fighting piping can be assembled and connected together with the liquid-cooled piping within the prefabrication compartment, eliminating the need for complex on-site installation. When the prefabrication compartment is loaded into the container, the fire-fighting system connection can be completed simply by connecting the secondary fire-fighting connector 601 to the container's primary gas fire-fighting piping 400, greatly simplifying the on-site installation process, improving assembly efficiency, and reducing safety risks caused by improper on-site installation. Through this integrated design, the battery pack prefabrication compartment 100 not only enhances functional integrity but also further strengthens the system's reliability and safety.

[0079] In some embodiments, a plurality of second cavities 102 are distributed in the height direction of the cabin 1, and the secondary water inlet pipeline assembly 4, the secondary water outlet pipeline assembly 5 and the secondary fire-fighting pipeline assembly 6 extend in the height direction of the cabin 1.

[0080] In this embodiment, taking the layout of a single-cluster energy storage device as an example, specifically, the high-voltage distribution box 2 and multiple battery packs 3 are arranged in a one-to-many relationship to form a single-cluster energy storage device. Multiple second cavities 102 are distributed along the height of the housing 1 to install multiple battery packs 3, thereby achieving a layered layout of the single-cluster energy storage device in the height direction. This design not only improves space utilization but also provides flexibility for the expansion of the single-cluster energy storage device.

[0081] The secondary water inlet piping assembly 4, the secondary water outlet piping assembly 5, and the secondary fire-fighting piping assembly 6 extend along the height of the cabin 1 to accommodate the distribution of multiple battery packs 3. This extended piping assembly ensures that the liquid-cooled inlet 301 and liquid-cooled outlet 302 of each battery pack 3 can be effectively connected to the cooling system, while also providing fire protection for each battery pack 3. Through this design, even when a single energy storage unit contains multiple battery packs 3, the cooling and fire-fighting requirements of each battery pack 3 can be met, thereby ensuring the operational safety and reliability of the entire prefabricated cabin.

[0082] In some cases, depending on the height layout of the battery pack 3, the secondary water inlet pipe assembly 4 and the secondary water outlet pipe assembly 5 are provided with pipes corresponding to the battery pack 3. For example, each layer of the battery pack 3 has a pipe corresponding to its height connected from the secondary water inlet pipe assembly 4 and the secondary water outlet pipe assembly 5.

[0083] Similarly, for the height layout of the battery pack 3, the secondary fire protection piping assembly 6 is equipped with piping corresponding to the battery pack 3. For example, each battery pack 3 on each floor has a piping corresponding to its height, which is led out from the secondary fire protection piping assembly 6 and set towards the battery pack 3.

[0084] In some embodiments, in the height direction of the cabin 1, the secondary water inlet connector 401 is located at the bottom of the secondary water inlet pipeline assembly 4, the secondary water outlet connector 501 is located at the top of the secondary water outlet pipeline assembly 5, and the secondary fire connector 601 is located at the top of the secondary fire pipeline assembly 6.

[0085] In this embodiment, the piping layout design of the prefabricated battery pack compartment 100 fully considers fluid dynamics and ease of operation. Specifically, in the height direction of the compartment 1, the secondary water inlet connector 401 is located at the bottom of the secondary water inlet pipe assembly 4, while the secondary water outlet connector 501 is located at the top of the secondary water outlet pipe assembly 5. This layout ensures that the coolant flows generally from bottom to top, and after flowing through the battery pack 3 inside the compartment 1, it forms a complete circulation system with the primary water inlet pipe 200 and the primary return water pipe 300 of the container. This design helps to improve cooling efficiency and ensures that the battery pack 3 remains within a suitable temperature range during operation.

[0086] Meanwhile, the secondary fire-fighting connector 601 is located at the top of the secondary fire-fighting piping assembly 6. This design means that the flow direction of the fire-fighting medium is from top to bottom, forming a unidirectional flow path. The advantage of this layout is that the fire-fighting medium can directly cover critical areas within the compartment 1, including the top of the battery pack 3 and critical equipment such as the high-voltage distribution box 2, thereby enabling rapid and effective fire extinguishing and protection in emergencies such as fires. Through this ingenious layout, the prefabricated battery pack compartment 100 not only optimizes the efficiency of the cooling system but also enhances the reliability and response speed of the fire-fighting system.

[0087] In some embodiments, the second cavity 102 is located on top of the first cavity 101 in the height direction of the cabin 1.

[0088] In this embodiment, the internal structural layout of the battery pack prefabricated compartment 100 is carefully designed to optimize space utilization and ease of operation. Specifically, the second cavity 102 is located above the first cavity 101 in the height direction of the compartment 1. This layout allows the high-voltage distribution box 2 to be installed in a relatively low position, facilitating routine maintenance and repair. Since the high-voltage distribution box 2 typically requires regular inspection and maintenance, placing it in a lower position reduces the labor intensity of operators during maintenance and improves work efficiency.

[0089] Meanwhile, battery pack 3 is installed in the second cavity 102, located high up in the cabin 1. This layout makes full use of the vertical space of the prefabricated cabin, significantly increasing the capacity of the entire energy storage system by increasing the number and size of battery pack 3. As the core component of the energy storage system, the increased capacity of battery pack 3 directly enhances the energy storage capacity of the prefabricated cabin, thereby meeting the energy storage requirements for higher power and longer duration. This design not only optimizes space utilization but also improves the overall performance and flexibility of the system.

[0090] In some embodiments, the battery pack prefabrication compartment 100 further includes a high-voltage box mounting component 7, which is connected to the high-voltage distribution box 2 and the compartment 1, and the high-voltage distribution box 2 is mounted on the compartment 1 through the high-voltage box mounting component 7.

[0091] Optionally, the high-voltage box mounting component 7 is in the form of a high-voltage box mounting strip, symmetrically arranged on both sides of the high-voltage distribution box 2, to limit the high-voltage distribution box 2 in both horizontal and vertical directions.

[0092] The prefabricated battery pack compartment 100 also includes a battery pack mounting component 8, which is connected to the battery pack 3 and the compartment 1, and the battery pack 3 is mounted on the compartment 1 through the battery pack mounting component 8.

[0093] Optionally, the battery pack mounting component 8 is in the form of a battery pack mounting strip, symmetrically arranged on both sides of the horizontal direction of the battery pack 3, thereby limiting the horizontal and vertical direction of the battery pack 3.

[0094] The battery pack prefabrication compartment 100 also includes: a first water pipe mounting component 9, which connects to the secondary water inlet pipe assembly 4 and the compartment 1, and installs the secondary water inlet pipe assembly 4 onto the compartment 1 via the first water pipe mounting component 9. The battery pack prefabrication compartment 100 also includes: a second water pipe mounting component 10, which connects to the secondary water outlet pipe assembly 5 and the compartment 1, and installs the secondary water outlet pipe assembly 5 onto the compartment 1 via the second water pipe mounting component 10.

[0095] Optionally, the first water pipe mounting component 9 and the second water pipe mounting component 10 adopt the form of water pipe clamps to fix the water pipes and ensure the stability and safety of coolant flow.

[0096] The prefabricated battery pack compartment 100 also includes a fire-fighting pipeline installation component 11, which is connected to the secondary fire-fighting pipeline assembly 6 and the compartment 1, and the secondary fire-fighting pipeline assembly 6 is installed on the compartment 1 through the fire-fighting pipeline installation component 11.

[0097] Optionally, the fire pipe installation component 11 adopts the form of a fire clamp to fix the fire pipe and ensure the reliability of the fire protection system.

[0098] In some embodiments, the cabin 1 includes: a cabin frame 103, having a first cavity 101 and a second cavity 102; a first cabin side plate 104, disposed on a first side of the cabin frame 103; and a second cabin side plate 105, disposed on a second side of the cabin frame 103, the second side being opposite to the first side on the cabin frame 103; wherein, one of the first cabin side plate 104 and the second cabin side plate 105 is provided with a secondary water inlet pipe assembly 4, and the other is provided with a secondary water outlet pipe assembly 5; and one of the first cabin side plate 104 and the second cabin side plate 105 is provided with a secondary fire-fighting pipe assembly 6.

[0099] Optionally, the secondary water inlet pipe assembly 4 is fixed to the first compartment side plate 104 by a water pipe clamp; the secondary water outlet pipe assembly 5 is fixed to the second compartment side plate 105 by a water pipe clamp; and the secondary fire-fighting pipe assembly 6 is fixed to the second compartment side plate 105 by a fire-fighting clamp.

[0100] In some cases, the cabin frame 103 consists of cabin uprights 1031 and cabin crossbars 1032. The cabin uprights 1031 and cabin crossbars 1032 are welded and fixed to ensure the structural stability of the cabin frame 103.

[0101] In some embodiments, the cabin 1 further includes: a cable tie 106 disposed on one of the first cabin side plate 104 and the second cabin side plate 105; a cabin mounting foot 107 disposed on the cabin frame 103, which connects to the container when the battery pack prefabrication cabin 100 is loaded into the container; and a cabin forklift crossbar 108 disposed on the cabin frame 103, which allows a forklift to lift the cabin 1 when the battery pack prefabrication cabin 100 is loaded into the container.

[0102] Optionally, cable tie 106 is welded and fixed to the first hull side plate 104 to secure cables and ensure neat and safe electrical connections. Hull mounting feet 107 are welded and fixed to the hull column 1031 for connection to the container when the battery pack prefabrication compartment 100 is loaded into the container.

[0103] Thanks to the inclusion of the forklift crossbar 108, the ease and efficiency of loading the prefabricated battery pack compartment 100 into the container are significantly improved. As a crucial auxiliary structure for the prefabricated compartment, the forklift crossbar 108 provides a stable support point for the forklift, enabling it to smoothly and quickly lift and move the entire prefabricated compartment into the container. This design not only reduces the labor intensity of manual handling but also lowers the risk of damage to the prefabricated compartment during transport, ensuring the integrity and safety of the prefabricated compartment and its internal components.

[0104] In some cases, the cabin 1 is also provided with a cabin top plate 109, which is located on top of the cabin frame 103. The cabin frame 103 is provided with an opening to facilitate the connection of the primary return water pipe 300 and the primary gas extinguishing pipe 400 to the battery pack prefabricated cabin 100.

[0105] This application also provides an energy storage container, including a container body and the aforementioned battery pack prefabrication compartment 100. The container body is provided with a power line, a primary water inlet pipe 200 and a primary water return pipe 300. The battery pack prefabrication compartment 100 is located inside the container body. The power line is electrically connected to the high-voltage distribution box 2 of the energy storage container. The primary water inlet pipe 200 is connected to the secondary water inlet connector 401 of the energy storage container, and the primary water return pipe 300 is connected to the secondary water outlet connector 501 of the energy storage container.

[0106] In this embodiment, the container is equipped with a power line, a primary water inlet pipe 200, and a primary water return pipe 300. These pipes and lines provide the necessary power and cooling support for the equipment inside the prefabricated compartment. Specifically, the battery pack prefabricated compartment 100 is installed inside the container. The power line is electrically connected to the high-voltage distribution box 2 of the energy storage container to ensure a stable power supply. The primary water inlet pipe 200 is connected to the secondary water inlet connector 401 of the energy storage container to provide coolant to the battery pack 3 inside the prefabricated compartment. The primary water return pipe 300 is connected to the secondary water outlet connector 501 of the energy storage container to recover the coolant, forming a complete cooling circulation system.

[0107] In some embodiments, the container is also provided with a primary gas extinguishing pipeline 400, which is connected to the secondary fire extinguishing connector 601 of the energy storage container.

[0108] In this embodiment, the container is also equipped with a primary fire suppression pipeline 400, further enhancing the safety of the energy storage container. The primary fire suppression pipeline 400 is connected to the secondary fire extinguishing connector 601 of the energy storage container, ensuring that the fire suppression system can respond quickly in emergencies, providing necessary fire protection for the equipment inside the prefabricated compartment. This design not only improves the overall safety of the energy storage container but also ensures timely and effective fire suppression and protection in emergencies such as fires.

[0109] Through this integrated design, the connection between the energy storage container and the prefabricated battery pack compartment 100 is closer and more efficient. The installation of the power line, primary water inlet pipe 200, primary water return pipe 300, and primary gas dissipation pipe 400 provides comprehensive support and protection for the equipment inside the prefabricated compartment, ensuring the stable operation and safety of the entire energy storage system.

[0110] In one specific implementation, the primary inlet pipe 200 and the primary return pipe 300 serve as primary water circuits, laid along the top and bottom of the container respectively. Branch interfaces are provided at corresponding positions on the pipes. Each interface is equipped with an NW26 male connector and a ball valve, which together connect with the secondary water circuit connectors of the secondary water circuit components, namely the secondary inlet pipe component 4 and the secondary outlet pipe component 5, specifically the secondary inlet connector 401 and the secondary outlet connector 501, both using NW26 female connectors. This completes the circulation of water between the prefabricated battery pack compartment and the container's water circuit.

[0111] The primary fire suppression pipeline 400 is laid along the top of the container. At corresponding positions on the pipeline, separate fire suppression interfaces are connected via internal threaded tees. Each interface is equipped with a cluster-level solenoid valve 12, which is then connected to the secondary fire suppression connector 601 of the secondary fire suppression pipeline assembly 6. This completes the connection between the fire suppression system of the prefabricated battery pack compartment and the container's fire suppression system.
