Description

Technical Field

[0001] This utility model belongs to the field of batteries, specifically an energy storage container and energy storage equipment. Background Technology

[0002] Traditional energy storage containers have a simple internal space layout that does not take into account the differences in specifications of different energy storage units, resulting in low space utilization. It is difficult to reasonably place equipment such as battery packs of different capacities and sizes, resulting in wasted space or crowded installation. Summary of the Invention

[0003] The purpose of this utility model is to provide an energy storage container and energy storage equipment, overcoming the problems of unreasonable space utilization in traditional energy storage containers.

[0004] The first aspect of this utility model provides an energy storage container, including a container body with one end open and a first door panel for opening or closing the open end of the container body;

[0005] The enclosure includes a battery compartment and an equipment compartment;

[0006] In the height direction of the battery compartment, the inner cavity of the battery compartment is divided into a first receiving cavity and at least one second receiving cavity, and in the height direction of the battery compartment, the size of the second receiving cavity is larger than the size of the first receiving cavity.

[0007] This invention divides a shipping container along its height into a first receiving cavity and at least one second receiving cavity, with the second receiving cavity being larger than the first receiving cavity. This differentiated design can accommodate energy storage units of different specifications; that is, energy storage units with smaller dimensions in the height direction are installed in the first receiving cavity, while energy storage units with larger dimensions in the height direction are installed in the second receiving cavity. This maximizes the utilization of space within the battery compartment and improves the rationality and compactness of the energy storage component layout. Compared to traditional single-specification shipping containers, this significantly improves space utilization, allowing for the rational and compact arrangement of more energy storage components of different capacities within a limited battery compartment space.

[0008] Furthermore, the aforementioned battery compartment and equipment compartment are arranged along the length of the enclosure, and are separated by a removable second door panel, which is parallel to the first door panel.

[0009] The second panel isolates the battery compartment and the equipment compartment, effectively preventing heat from spreading between the two compartments and affecting the normal operation of the equipment in the equipment compartment and the energy storage units in the battery compartment. Furthermore, the second panel is parallel to the first panel, allowing for installation of the energy storage units from a single direction simply by opening the first panel and removing the second panel. During assembly, it eliminates the need to reserve sufficient space on multiple sides for equipment entry, exit, and installation operations, significantly reducing the difficulty of site planning and preparation, especially in spaces with limited installation areas.

[0010] Furthermore, in the height direction of the battery compartment, the first receiving cavity is located above the second receiving cavity.

[0011] The larger second compartment below can accommodate large and heavy energy storage units. Placing them below makes the center of gravity of the entire battery compartment more stable, avoiding the risk of the container tipping over during transportation or use due to an excessively high center of gravity.

[0012] Furthermore, the equipment compartment is equipped with an interface, which enables external devices to connect to or from the equipment compartment.

[0013] The second aspect of this utility model provides an energy storage device, including an energy storage component, a temperature control system, a fire safety system, and the aforementioned energy storage container;

[0014] The energy storage assembly includes a first energy storage unit and a second energy storage unit; in the height direction of the battery compartment, the size of the first energy storage unit is smaller than that of the second energy storage unit; the first energy storage unit is installed in a first receiving cavity, and the second energy storage unit is installed in a second receiving cavity;

[0015] Temperature control and fire safety systems are installed in the equipment compartment.

[0016] The first energy storage unit, with a smaller height dimension, is installed in the first receiving cavity, while the second energy storage unit, with a larger height dimension, is installed in the second receiving cavity. This maximizes the utilization of space within the battery compartment and improves the rationality and compactness of the energy storage component layout. Compared to traditional single-dimensional containers, this significantly improves space utilization, allowing for the rational and compact arrangement of more energy storage components of varying capacities within the limited battery compartment space. An independent temperature control system within the equipment compartment regulates the battery compartment temperature, ensuring the energy storage units operate at suitable temperatures, further enhancing the reliability and stability of the energy storage equipment. An independent fire safety system within the equipment compartment enables rapid response to potential fire hazards within the battery compartment, minimizing losses.

[0017] Furthermore, the second energy storage unit includes a first sub-energy storage unit and a second sub-energy storage unit. The first sub-energy storage unit includes a battery pack, which includes n batteries arranged along the length of the battery compartment, where n is an integer greater than 1. The second sub-energy storage unit includes a high-voltage box and m batteries, where m is an integer less than n.

[0018] The first and second sub-energy storage units have the same dimensions in the height, length, and width directions of the battery compartment.

[0019] The identical dimensions ensure that the first and second sub-energy storage units can be arranged closely and evenly within the second housing, further optimizing the utilization efficiency of the battery compartment space. Whether stacked vertically or arranged in length and width, uniformity is achieved, avoiding space waste caused by size differences. This allows the limited battery compartment space to accommodate more energy storage components, indirectly improving the overall energy storage capacity of the energy storage container.

[0020] In addition, this utility model places the high-voltage box in the battery compartment, which effectively solves the problem that the equipment compartment cannot accommodate the high-voltage box due to limited space without the need for large-scale adjustments to the overall design of the energy storage container, thereby saving the cost and time incurred due to design changes.

[0021] Furthermore, the first sub-energy storage unit also includes a vertical support assembly and two horizontal support platforms; a battery pack is installed on each horizontal support platform, and the battery packs on the two horizontal support platforms are electrically connected; the vertical support assembly is located between the two horizontal support platforms and connects the two horizontal support platforms.

[0022] The battery packs of each horizontal support platform in the same first sub-energy storage unit can be electrically connected by arranging the upper and lower battery packs on one side in advance when they are loaded into the battery compartment of the energy storage container. After the whole unit is installed into the battery compartment, the operating space on one side used for battery pack series connection can be saved in the battery compartment, thereby improving the energy density of the energy storage components.

[0023] Furthermore, the second sub-energy storage unit also includes a vertical support assembly and two horizontal support platforms; the vertical support assembly is disposed between the two horizontal support platforms and connects the two horizontal support platforms.

[0024] The same number of batteries are installed on each horizontal support platform, and the batteries on the two horizontal support platforms are electrically connected; the high-voltage box is located in the space enclosed by the two horizontal support platforms and the vertical support components.

[0025] The second sub-energy storage unit uses the same support frame (vertical support components and two-layer horizontal support platforms) as the first sub-energy storage unit. During installation inside the energy storage container, since the second sub-energy storage unit is the same size as the first, the same installation tools, hoisting equipment, and installation procedures can be used. Workers do not need to adjust their operating methods for units of different sizes, reducing installation difficulty and shortening installation time.

[0026] Furthermore, the first energy storage unit includes a battery pack and a sub-support frame, with a battery pack mounted on each sub-support frame. The battery pack includes n batteries arranged along the length of the battery compartment.

[0027] Furthermore, the lowest second cavity contains three first sub-energy storage units and one second sub-energy storage unit arranged in a matrix; the remaining second cavities contain four first sub-energy storage units arranged in a matrix; and the first cavity contains four first energy storage units arranged in a matrix.

[0028] This layout allows for more efficient use of the battery compartment space, avoiding problems such as idle space or crowded equipment installation caused by unreasonable space allocation, and improving the overall space utilization rate of the energy storage container.

[0029] In addition, placing multiple second sub-energy storage units in the lower layer and arranging them in a close matrix reduces the center of gravity of the battery compartment and improves system stability.

[0030] The beneficial effects of this utility model are:

[0031] This invention divides a shipping container along its height into a first receiving cavity and at least one second receiving cavity, with the second receiving cavity being larger than the first receiving cavity. This differentiated design can accommodate energy storage units of different specifications; that is, the first energy storage unit with a smaller height dimension is installed in the first receiving cavity, and the second energy storage unit with a larger height dimension is installed in the second receiving cavity, maximizing the utilization of the battery compartment space and improving the rationality and compactness of the energy storage component layout. Compared to traditional single-specification shipping containers, this significantly improves space utilization, enabling the rational and compact layout of more energy storage components of different capacities within a limited battery compartment space.

[0043] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] In the description of this utility model, it should be noted that the terms "upper" and "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] This invention provides an energy storage container and an energy storage device incorporating it. Unlike traditional energy storage containers, the battery compartment can accommodate energy storage units of different specifications. Specifically, the battery compartment space is divided in the vertical direction to construct a first accommodating cavity and at least one second accommodating cavity, with the second accommodating cavity being larger than the first accommodating cavity. This differentiated design can accommodate energy storage units of different specifications. In the energy storage device, energy storage units with smaller vertical dimensions are installed in the first accommodating cavity, while energy storage units with larger vertical dimensions are installed in the second accommodating cavity, maximizing the utilization of the space within the battery compartment and improving the rationality and compactness of the energy storage device layout.

[0047] It should be noted that in this utility model, the dimensions of the multiple second receiving cavities can be the same or different. This embodiment mainly uses the example of multiple second receiving cavities having the same dimensions for illustration.

[0048] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0049] Example 1

[0050] like Figure 1 and Figure 2 As shown, the energy storage container in this embodiment is a rectangular box, which is formed by a box with one open end and a first door panel 13, wherein the first door panel 13 is used to open or close the open end of the box.

[0051] In this embodiment, for ease of description, the length direction of the rectangular box is defined as the x-direction, the width direction of the rectangular box is defined as the y-direction, and the height direction of the rectangular box is defined as the z-direction.

[0052] As can be seen from the figure, in this embodiment, the first door panel 13 is parallel to the yz plane and is composed of two sub-door panels, adopting a double door structure.

[0053] In the x-direction, the internal cavity of the box is divided into two independent and isolated compartments, which are defined as battery compartment 1 and equipment compartment 2, respectively.

[0054] Battery compartment 1, as the core functional area of ​​the entire energy storage container, is primarily used to house various energy storage units (mainly composed of multiple batteries 2222). Equipment compartment 2 houses the temperature control and fire safety systems. The temperature control system can monitor temperature changes within battery compartment 1 in real time. Once the temperature exceeds the preset optimal range, the system will quickly activate the cooling or heating devices to ensure that the energy storage units always operate in the optimal temperature environment, effectively extending the lifespan of the energy storage units and improving the overall performance of the energy storage equipment. The fire safety system can respond and initiate fire suppression procedures if it detects a fire hazard within battery compartment 1.

[0055] from Figure 2 As can be seen from the above, in this embodiment, the battery compartment 1 and the equipment compartment 2 are isolated by the second door panel 14. The second door panel 14 is parallel to the first door panel 13, and the second door panel 14 is fixedly connected to the housing in a detachable manner.

[0056] During charging and discharging, batteries not only generate a large amount of heat but may also release gases, potentially posing safety hazards such as fire and explosion. Isolating the battery compartment 1 and equipment compartment 2 with the second door panel 14 creates an effective barrier between the two areas, preventing the spread of danger. In the event of a safety accident in battery compartment 1, the second door panel 14 can largely prevent fire, high temperatures, and harmful gases from reaching equipment compartment 2, providing critical protection for the equipment within. The temperature control and fire suppression systems in equipment compartment 2 can promptly detect abnormalities and quickly activate cooling or fire extinguishing devices, improving equipment safety performance.

[0057] The second door panel 14 isolates the battery compartment 1 and the equipment compartment 2, effectively preventing heat from spreading between the two compartments and affecting the normal operation of the temperature control, fire protection, and energy storage units. Batteries generate a large amount of heat during charging and discharging. If this heat is uncontrolled and conducted to the equipment compartment 2, it may cause the electrical equipment inside to overheat, resulting in performance degradation, shortened lifespan, or even malfunction. Similarly, heat generated by some heat-generating devices in the equipment compartment 2, if transferred to the battery compartment 1, can also interfere with the energy storage unit, reducing the battery's charging and discharging efficiency and cycle life.

[0058] Furthermore, the second door panel 14 is parallel to the first door panel 13 and has a detachable structure. When installing the energy storage unit, only the first door panel 13 needs to be opened and the second door panel 14 removed to allow for installation from a single direction. (See [reference needed]). Figure 4 Install the energy storage unit in the direction indicated by the arrow. During assembly, it is not necessary to reserve sufficient space on multiple sides for equipment entry, exit, and installation operations. This effectively reduces the difficulty of site planning and preparation, especially for installation sites with limited space.

[0059] from Figure 2 As can be seen from the figure, in this embodiment, a support frame 15 is provided in the battery compartment 1. Its structure is in the form of a multi-layer support. A storage unit receiving cavity is constructed between two layers of supports parallel to the xy plane. At least one storage unit can be installed in each layer of storage unit receiving cavity.

[0060] In this invention, the battery compartment 1 is divided into two different types of receiving cavities in the z-direction according to their size, which can be defined as a first receiving cavity 11 and a second receiving cavity 12, wherein the size of the second receiving cavity 12 is larger than the size of the first receiving cavity 11; the number of the first receiving cavity 11 and the second receiving cavity 12 is not specifically limited, from Figure 2 As can be seen from the figure, this embodiment has four second receiving cavities 12 and one first receiving cavity 11, and the four second receiving cavities 12 are stacked in sequence and located below the first receiving cavity 11.

[0061] In other embodiments, the number and size of the first receiving cavity 11 and the second receiving cavity 12 can be adjusted according to changes in actual energy storage demand. If the demand for the first energy storage unit 21 increases, the number of the first receiving cavity 11 can be appropriately increased, and the number of the second receiving cavity 12 can be reduced accordingly; conversely, if the demand for the second energy storage unit 22 increases, the number of the second receiving cavity 12 can be increased.

[0062] The first receiving cavity 11 and the second receiving cavity 12 can accommodate energy storage units of different specifications, thereby maximizing the utilization of the space inside the battery compartment and improving the rationality and compactness of the energy storage equipment layout.

[0063] Example 2

[0064] like Figure 3 As shown, in this embodiment, the temperature control and fire safety system are installed in the equipment compartment of the energy storage container of Embodiment 1, and energy storage units of different specifications are installed in the battery compartment to construct the energy storage device of this embodiment.

[0065] The temperature control system can monitor temperature changes within battery compartment 1 in real time. If the temperature exceeds the preset optimal range, the system will quickly activate the cooling or heating devices to ensure the energy storage unit operates at the optimal temperature, effectively extending its lifespan and improving the overall performance of the energy storage device. The fire safety system can respond to any fire hazard detected within battery compartment 1 and initiate fire suppression procedures.

[0066] The equipment compartment may also be equipped with an interface 23. This interface allows for the connection of external devices to the equipment compartment or devices within the equipment compartment. When the fire safety system includes an ignition device (the ignition device is a related device disclosed in the prior art, such as the ignition unit disclosed in Chinese Patent CN117462891A), the interface 23 is preferably located on the top of the equipment compartment, and the ignition device can be installed on the top of the equipment compartment based on this interface.

[0067] In this embodiment, energy storage units of different specifications are collectively referred to as energy storage components.

[0068] Based on the dimensions in the z-direction, the energy storage component in this embodiment includes two types of energy storage units. For ease of description, these two types of energy storage units are defined as the first energy storage unit 21 and the second energy storage unit 22, respectively. The first energy storage unit 21 has a smaller dimension in the z-direction than the second energy storage unit 22. (Combined with...) Figure 3 , Figure 4 and Figure 5 As can be seen, since the first energy storage unit 21 has a relatively small size in the z-direction, it is installed in the first receiving cavity 11, while the second energy storage unit 22 has a larger size in the z-direction, so it is adapted to be installed in the second receiving cavity 12.

[0069] It should be noted that the figure above only schematically shows the bottommost second energy storage unit 22.

[0070] The following combination Figures 4 to 8 The second energy storage unit 22 will be described in detail.

[0071] from Figure 4 and Figure 5 As can be seen, the second energy storage unit 22 in this embodiment is mainly composed of two types of sub-energy storage units, which are defined as the first sub-energy storage unit 221 and the second sub-energy storage unit 222, respectively.

[0072] The structure of the first sub-energy storage unit 221 is as follows: Figure 6 and Figure 7 As shown, it includes a battery pack 210, a vertical support assembly 223, and a two-layer horizontal support platform 224.

[0073] The battery pack 210 includes 12 batteries 2222 arranged along the x-direction. In other embodiments, the specific number of batteries 2222 can be adjusted according to actual needs.

[0074] The horizontal support platform 224 is a rectangular frame, and the frame is constructed entirely of L-angle steel. L-angle steel has good strength and stability, and can provide reliable support for the energy storage units placed on it. A battery pack 210 is installed on each layer of the horizontal support platform 224, and the battery packs 210 on two layers of horizontal support platforms 224 are connected by an electrical connection bar.

[0075] A vertical support assembly 223 is positioned between two horizontal support platforms 224. The vertical support assembly 223 includes multiple support segments, each connected at its upper end to the upper horizontal support platform 224 and at its lower end to the lower horizontal support platform 224. Specifically, each support segment may include multiple first pairs of connecting pipes vertically fixed to the bottom surface of the upper horizontal support platform 224, and multiple second pairs of connecting pipes vertically fixed to the top surface of the lower horizontal support platform 224. The multiple first pairs of connecting pipes and the multiple second pairs of connecting pipes correspond one-to-one and are interlocked. The inner diameter of the first pair of connecting pipes may be larger than the outer diameter of the second pair of connecting pipes, or the outer diameter of the first pair of connecting pipes may be smaller than the inner diameter of the second pair of connecting pipes. The gap between the first and second pairs of connecting pipes after interlocking can also correct for installation errors when the battery pack 210 of the upper and lower support platforms is connected via an electrical connector.

[0076] In this embodiment, a battery pack 210 is installed on each horizontal support platform 224. Before actual installation, workers will electrically connect the upper and lower battery packs 210 within the same first sub-energy storage unit 221 outside the battery compartment 1. Because the connection is performed in a spacious, well-maintained external environment, the connection quality is more guaranteed, effectively reducing problems such as poor contact and lowering the probability of electrical faults during system operation. After the connection is completed, the entire unit is installed into the battery compartment 1. This method not only saves operating space on one side of the battery compartment 1 used for connecting the battery packs 210, but also reduces the risk of damage to the battery packs 210 and connecting lines during handling and installation within the battery compartment 1, thereby improving the energy density of the energy storage device.

[0077] The structure of the second sub-energy storage unit 222 is as follows: Figure 8As shown, the second sub-energy storage unit 222 includes a vertical support assembly 223 and two horizontal support platforms 224, identical to those in the first sub-energy storage unit 221. The vertical support assembly 223 connects the two horizontal support platforms 224. Unlike the battery pack 210 in the first sub-energy storage unit 221, the second sub-energy storage unit 222 includes a high-voltage box 2221 and multiple batteries 2222. Each horizontal support platform 224 has the same number of batteries 2222 installed, and the batteries 2222 on the two horizontal support platforms 224 are electrically connected. The high-voltage box 2221 is installed within the space enclosed by the two horizontal support platforms 224 and the vertical support assembly 223. This embodiment effectively solves the problem that the equipment compartment 2 cannot accommodate the high-voltage box 2221 due to limited space, without requiring large-scale adjustments to the overall design of the energy storage container. Previously, placing the high-voltage box 2221 in the equipment compartment 2 might require redesigning the internal layout of the equipment compartment 2, or even expanding the space of the equipment compartment 2. This would involve a series of complex tasks such as modifying the container structure, replacing materials, and replanning the internal wiring. This embodiment makes efficient use of the space in the battery compartment 1 to house the high-voltage box 2221, greatly reducing costs incurred due to design changes, including material and labor costs. At the same time, it avoids cumbersome design change procedures, significantly shortens the production cycle, and saves time.

[0078] It is worth noting that the second sub-energy storage unit 222 and the first sub-energy storage unit 221 adopt the same support frame structure (the support frame structure is the vertical support component 223 and two-layer horizontal support platform 224), and the first sub-energy storage unit 221 and the second sub-energy storage unit 222 have the same dimensions in the x, y, and z directions. When performing installation work inside the energy storage container, workers do not need to adjust their operating methods for the second sub-energy storage unit 222 and the first sub-energy storage unit 221; they can use the same installation tools, hoisting equipment, and installation procedures. For example, using the same forklift to hoist the first sub-energy storage unit 221 and the second sub-energy storage unit 222 to the designated location greatly reduces the installation difficulty and shortens the installation time.

[0079] Furthermore, during installation, workers can easily and evenly arrange the first sub-energy storage unit 221 and the second sub-energy storage unit 222. Whether stacked vertically or laid out in length and width, uniformity is achieved, avoiding wasted space. For example, when assembling the energy storage units within the second housing cavity 12, workers arrange the first and second sub-energy storage units 221 and 222 of the same size in an orderly manner, making full use of every inch of space, increasing the capacity of the energy storage components, and thus improving the overall energy storage capacity of the energy storage container.

[0080] The following combination Figure 9 The first energy storage unit 21 will be described in detail. Figure 9It includes two first energy storage units 21 arranged along the x-direction.

[0081] The first energy storage unit 21 mainly consists of a sub-support frame 211 and a battery pack 210 mounted on the sub-support frame 211; wherein the battery pack 210 includes 12 batteries 2222 arranged along the x direction. In other embodiments, the specific number of batteries 2222 can be adjusted according to actual needs.

[0082] Combination Figure 3 , Figure 4 and Figure 5 As can be seen, in this embodiment, each first receiving cavity 11 can be equipped with four first energy storage units 21, and the four first energy storage units 21 are arranged in a matrix.

[0083] Each second receiving cavity 12 can install four second energy storage units 22. The bottommost second receiving cavity 12 has three first sub-energy storage units 221 and one second sub-energy storage unit 222 arranged in a matrix. The remaining second receiving cavities 12 have four first sub-energy storage units 221 arranged in a matrix.

[0084] In this embodiment, a total of sixteen second energy storage units 22 and four first energy storage units 21 can be arranged.

[0085] By rationally planning the number and arrangement of energy storage units within the first and second accommodating cavities 11 and 12, the energy storage container in this embodiment fully utilizes its spatial advantages, achieving efficient placement and operation management of energy storage components, and effectively improving the overall performance of the energy storage container.
