[0001] This utility model relates to the field of container manufacturing technology, and more specifically, it relates to a large-capacity marine box-type power supply device. Background Technology

[0002] With the development of new energy technologies, their application in the maritime shipping sector has greatly facilitated the problem of power supply for transport vessels. Containerized energy storage, primarily based on lithium batteries, has become an indispensable part of new energy power generation due to its advantages such as large capacity, high integration, portability, strong adaptability, and scalability. As a key component of the energy storage system, the reliability and safety of the battery compartment structure are crucial for users, especially in open-air environments. The sealing and protection of the battery compartment, system cooling and heat dissipation, fire control, and battery cluster power management are all critical factors for the safety of the energy storage system.

[0003] Existing marine energy storage boxes are typically designed as 20-foot standard high cube containers, with the interior divided into four main areas: battery compartment, fire compartment, combiner compartment, and cooling compartment. Due to the limitations imposed by the China Classification Society's "E-25 Marine Containerized Mobile Power Supply" standard, the maximum battery capacity of a single battery compartment cannot exceed 2000 kWh. Even with higher density battery cells, it is impossible to break through the battery capacity limit of a single compartment, which particularly hinders the optimization of the range of large energy storage boxes.

[0040] Example 1:

[0041] The following is in conjunction with the appendix Figure 1 , Figure 3-6 and Figure 11 The present invention will be described in further detail below.

[0042] A high-capacity marine box-type power supply device, such as Figure 1 and Figure 3 As shown, the container is a 20-foot shipping container. The outermost surface of the container is a ceramic cotton layer 12, and the interior is fitted with a decorative panel layer 13. Several reinforcing members 14 are installed between the ceramic cotton layer 12 and the decorative panel layer 13. In actual production, the reinforcing members 14 are welded onto the container, and then ceramic cotton is laid on the outside of the reinforcing members 14 to ensure that the container meets the A60 fire protection requirements. The decorative panel layer 13 is used for aesthetics and separation. The front of the container is the functional area, and the rear is the battery area, which occupies most of the space inside the container. The functional area and the battery area are separated by an end partition 11 at the front. The rear battery area is divided into two symmetrical battery compartments 10 by a partition plate. The partition plate is made of steel plate with a thickness greater than 4.5mm according to E-25 requirements, and each compartment integrates a lithium iron phosphate battery system, supplemented by safety components such as cameras, smoke detectors, temperature sensors, combustible gas detectors, emergency lights, and fire sprinklers. The battery compartment 10 contains tightly fitted battery mounting racks 17, each fully loaded with battery packs 18, except for the rearmost battery mounting rack 17 which has a reserved space at its lower end for a ventilation damper. Safety components are installed around the battery mounting racks 17 within the battery compartment 10 for monitoring, emergency fire suppression, and lighting purposes. Each battery pack 18 has a cell capacity of 280Ah or higher, allowing for further increases in battery energy density and expansion of the single-pack capacity beyond the 2000KWh limit. The front functional area is mainly divided into a cooling compartment 20 on the left, a fire compartment 30 in the middle, and an integration compartment 40 on the right. The fire compartment 30 has a T-shaped vertical cross-section structure with a ventilation cavity at the top. The ventilation cavity extends to both sides above the cooling compartment 20 and the integration compartment 40. Emergency fans are installed within the ventilation cavity, primarily for ventilation of the battery area and rapid exhaust in emergencies. The lower part of the fire compartment 30 houses a fire extinguishing cylinder, a fire alarm, and an emergency ventilation control box. The fire alarm is electrically connected to the aforementioned safety components, and the emergency ventilation control box is electrically connected to the emergency fan equipment above. The principle is that once the safety components detect a fire, the fire alarm is triggered, activating the emergency fan equipment via the emergency ventilation control box to exhaust internal smoke and gas. The fire extinguishing cylinder is equipped with an automatic alarm and extinguishing system, which automatically releases the extinguishing gas or liquid within the cylinder in the event of a fire, or can be released manually. Figure 11As shown, the battery compartment 10 has a corresponding door 15 on its side. The fire compartment 30 has an openable cabinet door on its front, and the cooling compartment 20 and the integrated compartment 40 have corresponding openable cabinet doors on their left and right sides, respectively. The fire compartment itself is designed for ventilation, and the cooling compartment 20 and the integrated compartment 40 also have ventilation openings. The cooling compartment 20 cools the battery pack 18 on the battery mounting rack 17 through cooling pipes. The fire compartment 30 is connected to the battery compartment 10 through a fire vent and provides ventilation. The battery pack 18 flows into the integrated compartment 40. The integrated compartment 40 is electrically connected to the functional area and the battery area and related electronic components. Through the integrated compartment 40, the temperature, humidity, fire situation, and faults inside the compartment can be automatically monitored and responded to, and it also has a certain margin for manual operation.

[0043] The overall structure of the enclosure meets A60 fire protection requirements. The steel plate thickness in the fireproof area of ​​the battery compartment 10 should be greater than 5mm. L-shaped supports are installed on the walls, and the spacing of the L-shaped supports meets marine fire protection requirements. A60 cotton is laid on the wall panels and fixed with spot welds. The outermost layer is a decorative panel. The base frame of the battery compartment 10 is a 6mm thick steel plate covered with A60 cement for fireproofing and heat insulation. Square tubes are embedded in the steel plate to support the battery mounting frame 17. A movable frame is installed between the battery mounting frame 17 and the supporting square tubes. The movable frame, the embedded square tubes, and the battery mounting frame 17 are bolted together. The movable frame allows the A60 cement to be laid first, and the battery mounting frame 17 is installed after the A60 cement has cured, effectively ensuring the integrity of the cement laying. A layer of rubber pad is laid flat between the movable frame and the battery mounting frame 17 to buffer and level the battery mounting frame 17. Alternatively, shock absorbers can be used in conjunction with crossbeams to achieve the same effect. Pre-embedded pads are installed at the front and rear ends of the enclosure, with long bolts pre-welded to the pads. After the battery mounting bracket 17 is installed, the pre-embedded bolts are further secured to the battery mounting bracket 17 via adapters to prevent excessive deformation of the battery mounting bracket 17 due to shaking, which could compress the battery pack 18 on the battery mounting bracket 17. Support plates are pre-welded to the edges of the floor and ceiling for subsequent installation of decorative panels and the top and bottom joists.

[0044] like Figure 1 and Figure 6As shown, a liquid cooler 21 is installed inside the cooling compartment 20. The liquid cooler 21 is connected to a three-stage liquid cooling pipeline 22 installed in the battery area. The liquid cooling pipeline 22 is a circulation pipeline, and it passes through important partition surfaces such as the end partition wall 11 and the isolation wall 16 through MCT passage components 50 and is introduced into different areas. A set of liquid coolers 21 drives the three-stage liquid cooling pipeline for refrigeration circulation. The liquid cooler 21 regulates the temperature of the liquid coolant in the pipeline, thereby controlling the temperature of the battery pack 18. The primary liquid cooling is introduced into the battery compartment 10 through two MCT passage components 50 on the end partition wall 11. During the circulation of the primary pipeline in the battery compartment 10, the parts that need to pass through the isolation wall 16 also need to use MCT passage components 50 for transition, ensuring the integrity of the A60 fireproof partition system of each compartment. The secondary and tertiary pipelines to the battery pack 18 are then connected to the primary pipeline in a conventional manner.

[0045] like Figure 4 and Figure 5 As shown, an integrated audible and visual alarm 35, an MCT (Mechanical Control Unit) through-cabin component 50, and a venting-proof alarm 36 are installed on the left side of the ventilation cavity of the fire compartment 30. Correspondingly, the audible and visual alarm 35 and the MCT through-cabin component 50 are also installed on the back of the enclosure. The audible and visual alarm 35 and the venting-proof alarm 36 are electrically connected to the integrated compartment 40. A centrifugal exhaust port 37 with a fire damper is located at the center of the ventilation cavity of the fire compartment 30. A centrifugal exhaust fan 38 is installed inside the ventilation cavity of the fire compartment 30. Two centrifugal air inlets 39 with fire dampers are correspondingly opened at the lower end of the back of the enclosure. The centrifugal exhaust port 37 is connected to the centrifugal exhaust fan 38. The centrifugal exhaust fan 38 is connected to different battery compartments 10 inside the enclosure via a one-to-two pipe connection. The centrifugal air inlets 39 are connected to the interior of their respective battery compartments 10. Each battery compartment 10 is equipped with a fireproof damper at its centrifugal air inlet 39 and centrifugal air outlet 37. The centrifugal air outlet 37 uses a centrifugal exhaust fan 38 to drive the airflow through both battery compartments 10, simplifying the structure and reducing costs while ensuring effective ventilation. Since the gas produced by battery combustion is much less dense than air, the centrifugal air outlet 37 is positioned at the top, and the centrifugal air inlet 39 is positioned diagonally below to ensure effective ventilation within the battery compartment 10. A space of approximately one battery pack 18 is reserved at the lower end of the rear battery mounting bracket for installing the fireproof damper. External air enters the battery compartment 10 through the centrifugal air inlet 39 at the rear, rises, and is exhausted from the front of the housing through the centrifugal air outlet 37 by the centrifugal exhaust fan 38.

[0046] like Figure 4As shown, the integrated compartment 40 houses a combiner cabinet 41, to which the battery pack 18 is fed. The front of the integrated compartment 40, arranged from top to bottom, includes a window air conditioner 42, a human-machine interface control panel 43, an emergency stop button 46, an emergency fire extinguishing switch button 47, a communication port 44, and an electrical socket 45. All of these modules are electrically connected to the combiner cabinet 41. The human-machine interface control panel 43 is also electrically connected to key equipment such as safety components and emergency fan devices. The combiner cabinet 41 provides power, the human-machine interface control panel 43 provides human-machine interaction control, and the other components serve their respective functions. The auxiliary electrical system of the entire enclosure is integrated within the combiner cabinet 41. The battery pack 18 converts DC power to AC power via the inverter in the combiner cabinet 41, supplying power to lighting, cooling, fire protection, and other electrical equipment within the enclosure, and is connected to a UPS. The battery pack 18 can continue to operate stably even after a power outage. The window air conditioner 42 within the combiner compartment provides cooling for the other components. The high-voltage wiring harness and communication wiring harness inside the battery compartment 10 are connected to the combiner cabinet 41 through the MCT through-cabinet 50 at the bottom, which meets the fire protection requirements.

[0047] Example 2:

[0048] The following is in conjunction with the appendix Figure 7-10 The present invention will be described in further detail below.

[0049] The difference from Example 1 is that, as Figure 7-10 As shown, the centrifugal exhaust fan 38 was replaced with an induced draft fan 34, and the airflow path was redesigned. Specifically, natural air inlets 31 with fireproof dampers are opened on both sides of the ventilation cavity of the fire-fighting chamber, and a natural air outlet 33 with a fireproof damper is opened at the upper end of the back of the housing. A corresponding induced draft fan 34 is installed at the rear end of the battery compartment 10. The induced draft fan 34 is connected to the natural air outlet 33, and the natural air inlets 31 are connected to the downward-facing natural air duct 32 at the front end of the battery compartment 10. An integrated audible and visual alarm 35, an MCT penetration device 50, and a venting-proof alarm 36 are installed in the center of the ventilation cavity of the fire-fighting chamber 30. An audible and visual alarm 35 and an MCT penetration device 50 are also correspondingly installed on the back of the housing. The audible and visual alarm 35 and the venting-proof alarm 36 are electrically connected to the integrated compartment 40. External air enters the battery compartment 10 from the front end of the housing and flows downwards within the battery compartment 10 under the guidance of the duct. It is then drawn out of the battery compartment 10 by the exhaust fan 34 at the rear.

[0050] Example 3:

[0051] The following is in conjunction with the appendix Figure 2 The present invention will be described in further detail below.

[0052] The difference from Example 1 is that, as Figure 2As shown, liquid cooling is replaced with air cooling to lower the temperature of the battery pack 18. Specifically, an air-cooled outdoor unit 23 is installed inside the cooling chamber 20, and a separate air-cooled indoor unit 24 is installed in each of the two battery compartments 10 corresponding to the end partition wall 11. The air-cooled outdoor unit 23 and the air-cooled indoor unit 24 are electrically connected. One set of air-cooled outdoor unit 23 drives two air-cooled indoor units to regulate the temperature inside the battery compartment 10, thereby controlling the temperature of the battery pack 18.

[0053] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
