Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and more specifically, to an energy storage power pack and a stacked energy storage device. Background Technology

[0002] In the field of home energy storage devices, screws are a common mechanical connection method to ensure the secure installation of battery modules within the enclosure. However, as energy storage devices become increasingly complex and their scale continues to expand, the drawbacks of screw fixing have become increasingly apparent. Especially during installation and maintenance, the frequent disassembly and installation of a large number of screws not only consumes a significant amount of time and manpower but also greatly reduces the efficiency of installation and disassembly work.

[0003] Therefore, how to design an energy storage and charging pack that can effectively reduce the complexity of battery module installation while having a simple structure and reliable performance has become an urgent problem to be solved. Utility Model Content

[0004] This invention aims to at least solve the problems of low efficiency in battery module installation and disassembly.

[0005] Therefore, the first aspect of this utility model provides an energy storage and power supply package.

[0006] A second aspect of this invention provides a stacked energy storage device.

[0007] In view of this, the first aspect of the present invention provides an energy storage and charging pack, comprising: a housing having an installation opening; a battery module detachably installed in the housing through the installation opening; a cover plate covering the installation opening for closing the installation opening; and at least one limiting member disposed between the battery module and the cover plate, one end of the limiting member abutting against at least a portion of the battery module, and the other end of the limiting member abutting against the cover plate, wherein when the cover plate closes the installation opening, it can apply a force to the direction of the battery module through the limiting member.

[0008] This utility model provides an energy storage power pack that enables rapid installation and reliable fixation of the battery module. The battery module simply needs to be inserted directly into the housing through the mounting port, eliminating the need for additional fixing tools and complex procedures, significantly simplifying the installation process and improving efficiency. The two ends of the limiting member abut against the battery module and the cover plate respectively, forming a mechanical constraint structure that effectively restricts battery module displacement and sway, ensuring precise alignment during equipment operation and maintenance. Furthermore, compared to the traditional method of using multiple bolts to fix the battery module, this energy storage power pack, through the cooperation of the limiting member and the cover plate, eliminates the need to install and remove a large number of bolts. The battery module is directly inserted into the housing through the mounting port, and fixed by the two ends of the limiting member abutting against the battery module and the cover plate respectively, saving installation time and improving installation efficiency.

[0009] In some embodiments, the limiting member may optionally include: a limiting main board disposed between the battery module and the cover plate; at least one first abutting portion disposed at one end of the limiting main board near the battery module, the first abutting portion being used to abut against a portion of the battery module; and a second abutting portion disposed at one end of the limiting main board near the cover plate, the second abutting portion being used to abut against the cover plate.

[0010] In these embodiments, the limiting component includes a limiting main board, at least one first abutment portion, and a second abutment portion. The limiting main board is disposed between the battery module and the cover plate, and its function is to provide a stable support platform, separating the battery module from the cover plate by a certain distance, thereby creating good space conditions for the installation and fixation of the battery module. The first abutment portion is located at the end of the limiting main board near the battery module and can abut against part of the battery module. This abutment method can effectively prevent the battery module from shifting and shaking within the enclosure, ensuring that the battery module maintains a stable position after installation. The second abutment portion is disposed at the end of the limiting main board near the cover plate and is used to abut against the cover plate. This not only further enhances the stability of the entire limiting structure, but also evenly transmits the fixing force of the battery module to the cover plate, preventing deformation or damage to the cover plate due to excessive local pressure. At the same time, this design avoids frequent disassembly and assembly of a large number of screws during installation and maintenance, effectively simplifying the installation process, reducing the complexity of installation, improving the efficiency of installation and maintenance, and thus improving the reliability and practicality of the entire energy storage battery pack.

[0011] In some embodiments, optionally, the first abutting portion is a first bending portion formed by bending one end of the limiting motherboard near the battery module toward one side of the limiting motherboard; the second abutting portion is a second bending portion formed by bending one end of the limiting motherboard near the cover plate toward one side of the limiting motherboard; wherein the bending directions of the first bending portion and the second bending portion are the same.

[0012] In these embodiments, by bending both ends of the limiting motherboard to the same side to form a first bending portion and a second bending portion, the structure of the limiting component is simplified, the number of parts is reduced, and production costs and assembly complexity are lowered. The shape of the bending portion makes closer contact with the battery module and the cover plate, effectively preventing displacement of the battery module and improving the installation stability and reliability of the battery module. In addition, the same bending direction makes the limiting component more evenly stressed, enhancing the overall structural strength and durability and extending the service life of the equipment. At the same time, this design facilitates installation and disassembly, improves maintenance efficiency, and meets the needs of energy storage devices for efficient and stable installation methods.

[0013] In some embodiments, the limiting member may optionally include: at least one support plate disposed on the limiting main plate and disposed along the direction from the cover plate to the battery module; and a third abutting portion disposed at one end of the support plate near the battery module, the third abutting portion abutting against the battery module.

[0014] In these embodiments, by providing a support plate along the direction from the cover plate to the battery module on the limiting main board, and by providing a third abutment at the end of the support plate near the battery module, the limiting component can provide multi-point support and abutment for the battery module, enhancing the fixing effect of the battery module and preventing its displacement. Furthermore, this design optimizes the mechanical properties of the limiting component, making force transmission more uniform and avoiding local stress concentration, thereby extending the service life of both the limiting component and the battery module. Simultaneously, the design of the support plate and abutment simplifies the installation process, making installation and maintenance more convenient, reducing operating time and labor costs, and further improving the reliability and practicality of the energy storage device.

[0015] In some embodiments, the limiting member may optionally include: at least one support plate disposed on the limiting main plate and disposed along the direction from the cover plate to the battery module; one end of the support plate near the cover plate abuts against the second abutting portion for supporting the second abutting portion.

[0016] In these embodiments, the stability of the entire limiting structure is further improved by providing a support plate along the direction from the cover plate to the battery module on the limiting main board, and by the abutment between the support plate and the second abutment portion.

[0017] In some embodiments, the energy storage power pack may optionally include a circuit board disposed on the side of the battery module near the cover plate and located between the second abutment and the battery module.

[0018] In these embodiments, a circuit board is positioned on the side of the battery module near the cover plate, between the second abutment and the battery module. This provides effective protection for the circuit board, preventing damage from direct impacts and improving its reliability. Simultaneously, this layout allows for a tighter and more direct connection between the circuit board and the battery module, shortening the electrical connection path, reducing resistance and energy consumption, and improving power transmission efficiency. Furthermore, the optimized spatial layout improves the internal structure of the energy storage power pack, enabling collaborative operation among components and further enhancing the overall performance and stability of the energy storage device, providing a strong guarantee for the efficient operation of the energy storage system.

[0019] In some embodiments, optionally, the limiting main board is provided with one of a guide groove and a guide block, and the housing is provided with the other of a guide groove and a guide block, the guide block being used to cooperate with the guide groove; wherein, the guide groove extends along the installation direction of the battery module.

[0020] In these embodiments, by setting guide grooves and guide blocks on the limiting motherboard and the housing respectively, and extending the guide grooves along the installation direction of the battery module, rapid and precise positioning between the limiting component and the battery module can be achieved. During battery module installation, the cooperation of the guide blocks and guide grooves guides the limiting motherboard to move smoothly along a predetermined track, effectively preventing offset and shaking during installation, thus improving installation accuracy and efficiency. Simultaneously, this guiding structure provides additional stability to the limiting motherboard and battery module during operation, preventing displacement caused by vibration or other external forces, ensuring stable installation and reliable operation of the battery module. Furthermore, this design facilitates subsequent maintenance and replacement, making the assembly and disassembly process of the entire energy storage charging pack more convenient, further enhancing the maintainability and practicality of the equipment.

[0021] In some embodiments, the number of limiting members may be two, and the two limiting members are arranged symmetrically about the center line of the battery module.

[0022] In these embodiments, the use of two limiting components symmetrically arranged around the centerline of the battery module ensures uniform force distribution within the enclosure, effectively preventing tilting or displacement due to uneven force and improving the installation stability and reliability of the battery module. The symmetrical structural design also facilitates installation and disassembly, enabling operators to quickly and accurately assemble the limiting components, thus improving work efficiency. Simultaneously, this symmetrical layout helps optimize the internal space utilization of the energy storage charging pack, making the layout of each component more rational, enhancing the overall structural compactness and aesthetics, and providing strong support for the large-scale production and application of energy storage devices.

[0023] In some embodiments, the energy storage charging pack may optionally include: a first elastic buffer disposed between the cover and the limiting member; and / or a second elastic buffer disposed between the side wall of the housing opposite to the mounting opening and the battery module.

[0024] In these embodiments, by setting a first elastic buffer and a second elastic buffer, the fixing method of the battery module can be further optimized, mitigating the adverse effects of external impacts or vibrations on the battery module. Specifically, when the device is subjected to an external impact, the elastic buffer can quickly deform to absorb the impact energy, effectively reducing the peak impact force transmitted to the battery module. Under vibration conditions, the elastic characteristics of the buffer can form a flexible connection between the battery module and the vibration source, reducing vibration transmission efficiency and thus weakening the cumulative damage of vibration to the battery module. From a structural perspective, this design also enhances the adaptability of the energy storage battery pack, enabling it to better cope with changes in operating conditions under different usage environments, ensuring that the battery module is always in a stable working state, further improving the safety and reliability of the energy storage system, and providing a strong guarantee for the long-term stable operation of the energy storage device. In addition, by setting the first elastic buffer and the second elastic buffer, rigid connections between the battery module and the housing and limiting components are avoided, effectively ensuring the safety of the battery module.

[0025] In some embodiments, the energy storage charging pack may optionally include: a connector disposed in the housing, with at least a portion of the connector located inside the housing and at least a portion of the connector located outside the housing, the portion of the connector located inside the housing being used to connect to the battery module and the portion of the connector located outside the housing being used to connect to the main energy storage pack; foot pads disposed at the bottom of the housing for supporting the housing; and clearance holes disposed at the top of the housing for clearing the support feet of the main energy storage pack.

[0026] In these embodiments, the overall functionality and user experience of the energy storage power pack are optimized by incorporating connectors, feet, and clearance holes on the enclosure. The connector design enables efficient electrical connections between the inside and outside of the enclosure, ensuring stable and reliable power and signal transmission, and simplifying installation and maintenance. The feet enhance the stability and vibration damping performance of the enclosure, effectively preventing tipping and vibration damage during operation or handling. The clever layout of the clearance holes provides space for the support feet of the main energy storage pack, making the installation of the power pack and the main energy storage pack more compact and coordinated, improving space utilization and overall integration. These designs collectively enhance the practicality, reliability, and adaptability of the energy storage power pack, meeting the requirements of complex installation environments and long-term stable operation.

[0027] The second aspect of this utility model provides a stacked energy storage device, comprising: an energy storage main package; and at least one energy storage power supply package as described in any of the technical solutions of the first aspect, wherein the energy storage power supply package is disposed at the bottom of the energy storage main package.

[0028] The stacked energy storage device provided by this utility model includes a main energy storage unit and at least one energy storage power supply unit as described in any of the technical solutions of the first aspect, with the power supply unit disposed at the bottom of the main energy storage unit. Since this stacked energy storage device includes the energy storage power supply unit as described in any of the technical solutions of the first aspect, the stacked energy storage device provided by this utility model also possesses all the beneficial effects of the energy storage power supply unit as described in any of the technical solutions of the first aspect, which will not be elaborated further here.

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] 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. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] The following reference Figures 1 to 9 This invention describes an energy storage power pack and a stacked energy storage device proposed according to some embodiments of the present invention.

[0045] According to an embodiment of the first aspect of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first aspect of this utility model discloses an energy storage power pack 1, including a housing 11, a battery module 12, a cover plate 13, and at least one limiting member 14. The housing 11 has an installation opening 112 through which the battery module 12 is detachably installed within the housing 11. The cover plate 13 is placed over the installation opening 112 to close it, and at least one limiting member 14 is disposed between the battery module 12 and the cover plate 13. One end of the limiting member 14 abuts against at least a portion of the battery module 12, and the other end abuts against the cover plate 13. When the cover plate 13 closes the installation opening 112, the limiting member 14 can apply a force in the direction of the battery module 12, ensuring that the battery module 12 is securely installed within the housing 11.

[0046] The energy storage power pack 1 provided by this utility model enables rapid installation and reliable fixation of the battery module 12. The battery module 12 only needs to be directly inserted into the housing 11 through the mounting port 112, without the need for additional fixing tools and complex procedures, significantly simplifying the installation process and improving efficiency. The two ends of the limiting member 14 abut against the battery module 12 and the cover plate 13 respectively, forming a mechanical constraint structure, effectively limiting the displacement and shaking of the battery module, and ensuring that it remains in a precise alignment state during equipment operation and maintenance. At the same time, compared with the traditional solution of fixing the battery module with multiple bolts, the energy storage power pack 1 of this application, through the cooperation of the limiting member 14 and the cover plate 13, eliminates the need to install and remove a large number of bolts. The battery module 12 is directly inserted into the housing 11 through the mounting port 112, and is fixed by the two ends of the limiting member 14 abutting against the battery module 12 and the cover plate 13 respectively, saving installation time and improving installation efficiency.

[0047] Since one end of the limiting member 14 abuts against at least part of the battery module 12, a certain installation position can be reserved on the surface of the battery module 12 to facilitate the installation of other parts.

[0048] In some embodiments, the limiting member 14 may optionally be made of an elastic material to provide a certain cushioning effect and reduce the vibration and impact of the battery module 12 during operation.

[0049] In some embodiments, the cover plate 13 can be fixed to the housing 11 in various ways, such as by bolts, clips, etc. Different fixing methods are suitable for different application scenarios and needs.

[0050] In some embodiments, the battery module 12 may be connected to the housing 11 via a slide rail, slot, or other means to facilitate installation and disassembly.

[0051] In some embodiments, the limiting member 14 may optionally include: a limiting main board 142 disposed between the battery module 12 and the cover plate 13; at least one first abutting portion 144 disposed at one end of the limiting main board 142 near the battery module 12, the first abutting portion 144 being used to abut against a portion of the battery module 12; and a second abutting portion 146 disposed at one end of the limiting main board 142 near the cover plate 13, the second abutting portion 146 being used to abut against the cover plate 13.

[0052] In these embodiments, the limiting member 14 includes a limiting main board 142, at least one first abutting part 144, and a second abutting part 146. The limiting main board 142 is disposed between the battery module 12 and the cover plate 13, and its function is to provide a stable support platform, separating the battery module 12 from the cover plate 13 by a certain distance, thereby creating good space conditions for the installation and fixation of the battery module 12. The first abutting part 144 is located at the end of the limiting main board 142 near the battery module 12, and can abut against part of the battery module 12. Through this abutting method, displacement and shaking of the battery module 12 within the housing 11 can be effectively prevented, ensuring that the battery module 12 maintains a stable position after installation. The second abutting part 146 is disposed at the end of the limiting main board 142 near the cover plate 13, and is used to abut against the cover plate 13. This not only further enhances the stability of the entire limiting structure, but also evenly transmits the fixing force of the battery module 12 to the cover plate 13, preventing deformation or damage to the cover plate 13 due to excessive local pressure. At the same time, this design avoids frequent disassembly and assembly of numerous screws during installation and maintenance, effectively simplifying the installation process, reducing installation complexity, and improving installation and maintenance efficiency, thereby enhancing the reliability and practicality of the entire energy storage and charging pack 1.

[0053] Understandably, during installation, this application only requires installing the battery module 12 into the housing 11, then abutting the first abutting part 144 of the limiting member 14 against the battery module 12, and finally fixing the cover plate 13 at the mounting opening 112 and pressing it against the second abutting part 146. This allows the cover plate 13 to apply a fixing force to the battery module 12, ensuring its stability. Furthermore, the limiting member 14 does not need to be connected to any other parts; it only needs to be placed between the battery module 12 and the cover plate 13 for abutment. Therefore, this installation method is convenient, as it allows for the fixing of the battery module 12 without removing multiple bolts.

[0054] The limiting component 14 can be made of different materials, such as metal, plastic, or composite materials, depending on actual needs. Metal materials (such as aluminum alloys) have high strength and durability, making them suitable for high-strength energy storage devices. Plastic materials (such as polycarbonate) have good insulation properties and lightweight characteristics, making them suitable for weight-sensitive portable energy storage devices.

[0055] The shape and size of the limiting motherboard 142 can be customized according to the shape and size of the battery module 12. For example, for an irregularly shaped battery module 12, the limiting motherboard 142 can be designed to match its shape to ensure better fit and fixation.

[0056] In some embodiments, optionally, the first abutment portion 144 is a first bending portion 1442 formed by bending one end of the limiting motherboard 142 near the battery module 12 toward one side of the limiting motherboard 142; the second abutment portion 146 is a second bending portion 1462 formed by bending one end of the limiting motherboard 142 near the cover plate 13 toward one side of the limiting motherboard 142; wherein the bending directions of the first bending portion 1442 and the second bending portion 1462 are the same.

[0057] In these embodiments, by bending both ends of the limiting mainboard 142 to the same side to form a first bending portion 1442 and a second bending portion 1462, the structure of the limiting member 14 is simplified, the number of parts is reduced, and production costs and assembly complexity are lowered. The shape of the bending portion makes closer contact with the battery module 12 and the cover plate 13, effectively preventing displacement of the battery module 12 and improving the installation stability and reliability of the battery module 12. In addition, the same bending direction makes the limiting member 14 more evenly stressed, enhancing the strength and durability of the overall structure and extending the service life of the device. At the same time, this design facilitates installation and disassembly, improves maintenance efficiency, and meets the needs of energy storage devices for efficient and stable installation methods.

[0058] Specifically, during installation, when the battery module 12 is placed into the housing 11 through the mounting port 112, the first bent portion 1442 of the limiting main board 142 is in close contact with the surface of the battery module 12. When the cover plate 13 is closed, the second bent portion 1462 contacts the cover plate 13. The cover plate 13 applies pressure to the limiting main board 142 through the second bent portion 1462, and then transmits the pressure to the battery module 12 through the first bent portion 1442, ensuring the stability of the battery module 12 in the housing 11.

[0059] In some embodiments, the limiting member 14 may optionally include: at least one support plate 148 disposed on the limiting main plate 142 and disposed along the direction from the cover plate 13 to the battery module 12; and a third abutting portion 1482 disposed on one end of the support plate 148 near the battery module 12, the third abutting portion 1482 abutting against the battery module 12.

[0060] In these embodiments, a support plate 148 is disposed on a limiting main plate 142 and extends along the direction from the cover plate 13 to the battery module 12. A third abutment portion 1482 is provided at one end of the support plate 148 near the battery module 12, which abuts tightly against the battery module 12, thereby providing additional support and positioning functions for the battery module 12.

[0061] By providing a support plate 148 along the direction from the cover plate 13 to the battery module 12 on the limiting main board 142, and providing a third abutment portion 1482 at the end of the support plate 148 near the battery module 12, the limiting member 14 can provide multi-point support and abutment for the battery module 12, enhancing the fixing effect of the battery module 12 and preventing its displacement. Furthermore, this design optimizes the mechanical properties of the limiting member 14, making force transmission more uniform and avoiding local stress concentration, thereby extending the service life of the limiting member 14 and the battery module 12. Simultaneously, the design of the support plate 148 and the abutment portion simplifies the installation process, making installation and maintenance more convenient, reducing operating time and labor costs, and further improving the reliability and practicality of the energy storage device.

[0062] In some embodiments, the limiting member 14 may optionally include: at least one support plate 148 disposed on the limiting main plate 142 and disposed along the direction from the cover plate 13 to the battery module 12; one end of the support plate 148 near the cover plate 13 abuts against the second abutting portion 146 for supporting the second abutting portion 146.

[0063] In these embodiments, the limiting member 14 further includes at least one support plate 148. The support plate 148 is disposed on the limiting main plate 142 and extends along the direction from the cover plate 13 to the battery module 12. One end of the support plate 148 near the cover plate 13 abuts against the second abutting portion 146 to support the second abutting portion 146. The support plate 148, through its abutment against the second abutting portion 146, enhances the overall stability of the limiting member 14, ensuring that the cover plate 13 can apply a uniform force to the battery module 12 when closed.

[0064] In some embodiments, the energy storage power pack 1 may optionally include a circuit board 15 disposed on the side of the battery module 12 near the cover plate 13 and located between the second abutment portion 146 and the battery module 12.

[0065] In these embodiments, the circuit board 15 is mounted on the side of the battery module 12 near the cover plate 13, specifically between the second abutment portion 146 and the battery module 12. This arrangement allows the circuit board 15 to form a compact integrated layer between the battery module 12 and the cover plate 13.

[0066] The main function of circuit board 15 is to realize the electrical connection and signal transmission between battery module 12 and external devices (such as energy storage main pack 2). It is responsible for the distribution and conversion of electrical energy and monitoring the working status of battery module 12. Of course, circuit board 15 may also have other functions, which are not limited here.

[0067] Specifically, the circuit board 15 can be fixed to the side of the battery module 12 near the cover plate 13 to ensure the stability of the circuit board 15 installation. Since the first abutting part 144 abuts against part of the battery module 12, the surface of the battery module 12 near the cover plate 13 also has a certain mounting position where the circuit board 15 can be installed.

[0068] A circuit board 15 is positioned on the side of the battery module 12 near the cover plate 13, between the second abutment portion 146 and the battery module 12. This arrangement effectively protects the circuit board 15 from direct impact, preventing damage and improving its reliability. Furthermore, this layout allows for a tighter and more direct connection between the circuit board 15 and the battery module 12, shortening the electrical connection path, reducing resistance and energy consumption, and improving power transmission efficiency. In addition, the optimized spatial layout improves the internal structure of the energy storage power pack 1, enabling collaborative operation among components and further enhancing the overall performance and stability of the energy storage device, providing a strong guarantee for the efficient operation of the energy storage system.

[0069] In some embodiments, the circuit board 15 may be a BMS (Battery Management System) board.

[0070] In some embodiments, optionally, the limiting motherboard 142 is provided with one of a guide groove 116 and a guide block 1422, and the housing 11 is provided with the other of a guide groove 116 and a guide block 1422, wherein the guide block 1422 is used to cooperate with the guide groove 116; wherein the guide groove 116 extends along the installation direction of the battery module 12.

[0071] In these embodiments, the limiting main board 142 is provided with one of a guide groove 116 and a guide block 1422, while the housing 11 is provided with the other of a guide groove 116 and a guide block 1422. The guide block 1422 cooperates with the guide groove 116 to ensure that the limiting main board 142 moves smoothly along a predetermined track, thereby making the first abutment portion 144 precisely aligned with the battery module 12.

[0072] By setting guide grooves 116 and guide blocks 1422 on the limiting main board 142 and the housing 11 respectively, and extending the guide grooves 116 along the installation direction of the battery module 12, rapid and precise positioning between the limiting component 14 and the battery module 12 can be achieved. During battery module 12 installation, the cooperation between the guide blocks 1422 and the guide grooves 116 guides the limiting main board 142 to move smoothly along a predetermined track, effectively preventing offset and shaking during installation, thus improving installation accuracy and efficiency. Simultaneously, this guiding structure provides additional stability to the limiting main board 142 and the battery module 12 during operation, preventing displacement caused by vibration or other external forces, ensuring the stable installation and reliable operation of the battery module 12. Furthermore, this design facilitates subsequent maintenance and replacement, making the assembly and disassembly process of the entire energy storage and charging pack 1 more convenient, further enhancing the maintainability and practicality of the equipment.

[0073] In some embodiments, the number of limiting members 14 is optionally two, and the two limiting members 14 are arranged symmetrically about the center line of the battery module 12.

[0074] In these embodiments, there are two limiting members 14, both of which are disposed on the side of the battery module 12 near the cover plate 13, and are arranged symmetrically about the center line of the battery module 12. The center line of the battery module 12 includes the horizontal center line and the vertical center line of the surface of the battery module 12 near the cover plate 13.

[0075] The use of two limiting members 14 symmetrically arranged around the centerline of the battery module 12 ensures uniform force distribution within the housing 11, effectively preventing tilting or displacement due to uneven force distribution and improving the installation stability and reliability of the battery module 12. The symmetrical structural design also facilitates installation and disassembly, enabling operators to quickly and accurately assemble the limiting members 14, thus improving work efficiency. Simultaneously, this symmetrical layout helps optimize the internal space utilization of the energy storage charging pack 1, making the layout of components more rational, enhancing the overall structural compactness and aesthetics, and providing strong support for the large-scale production and application of energy storage devices.

[0076] In some embodiments, optionally, when the battery module 12 is installed from the back, one limiting member 14 is disposed at an upper position on the side of the battery module 12 near the cover plate 13, and another limiting member 14 is disposed at a lower position on the side of the battery module 12 near the cover plate 13.

[0077] In some embodiments, the energy storage charging pack 1 may optionally include: a first elastic buffer 16 disposed between the cover plate 13 and the limiting member 14; and / or a second elastic buffer 17 disposed between the side wall of the housing 11 opposite to the mounting port 112 and the battery module 12.

[0078] In these embodiments, by providing a first elastic buffer 16 and a second elastic buffer 17, the fixing method of the battery module 12 can be further optimized, mitigating the adverse effects of external impacts or vibrations on the battery module 12. Specifically, when the device is subjected to an external impact, the elastic buffer can quickly deform to absorb the impact energy, effectively reducing the peak impact force transmitted to the battery module 12. Under vibration conditions, the elastic characteristics of the buffer can form a flexible connection between the battery module 12 and the vibration source, reducing vibration transmission efficiency and thus weakening the cumulative damage of vibration to the battery module 12. From a structural perspective, this design also enhances the adaptability of the energy storage power pack 1, enabling it to better cope with changes in operating conditions under different usage environments, ensuring that the battery module 12 is always in a stable working state, further improving the safety and reliability of the energy storage system, and providing a strong guarantee for the long-term stable operation of the energy storage device. In addition, by setting the first elastic buffer 16 and the second elastic buffer 17, the rigid connection between the battery module 12 and the housing 11 and the limiting member 14 is avoided, which effectively ensures the safety of the battery module 12.

[0079] In some embodiments, the first elastic buffer 16 or the second elastic buffer 17 may optionally include at least one or a combination of the following: foam, rubber, polyurethane foam and plastic.

[0080] In these embodiments, these materials possess excellent elasticity and flexibility, effectively absorbing and dispersing the forces exerted on the battery module 12 by the limiting member 14 and the housing 11, preventing damage to the battery module 12 due to excessive local pressure. Simultaneously, they significantly reduce the impact of vibration and shock on the battery module 12 during equipment operation or transportation, lowering the risk of internal structural damage and extending its service life. Furthermore, the lightweight nature of these materials helps reduce the overall weight of the energy storage device, facilitating installation and handling, while their corrosion resistance and durability ensure the long-term stable performance of the elastic buffer in various environments, reducing maintenance costs and improving the reliability and economy of the energy storage system.

[0081] In some embodiments, optionally, the energy storage charging pack 1 further includes: a connector 18 disposed in the housing 11, at least a portion of the connector 18 being located inside the housing 11 and at least a portion of the connector 18 being located outside the housing 11, the portion of the connector 18 located inside the housing 11 being used to connect to the battery module 12, and the portion of the connector 18 located outside the housing 11 being used to connect to the main energy storage pack 2; foot pads 19 disposed at the bottom of the housing 11 for supporting the housing 11; and clearance holes 114 disposed at the top of the housing 11 for clearing the support feet 22 of the main energy storage pack 2.

[0082] In these embodiments, the overall functionality and user experience of the energy storage power pack 1 are optimized by incorporating connectors 18, feet 19, and clearance holes 114 on the housing 11. The connector 18 enables efficient electrical connections between the inside and outside of the housing 11, ensuring stable and reliable power and signal transmission and simplifying installation and maintenance. The feet 19 enhance the stability and vibration damping performance of the housing 11, effectively preventing tipping and vibration damage during operation or handling. The clever layout of the clearance holes 114 provides space for the support feet 22 of the main energy storage pack 2, making the installation of the energy storage power pack 1 and the main energy storage pack 2 more compact and coordinated, improving space utilization and overall integration. These designs collectively enhance the practicality, reliability, and adaptability of the energy storage power pack 1, meeting the requirements of complex installation environments and long-term stable operation.

[0083] In some embodiments, the mounting port 112 is optionally located on the top of the housing 11.

[0084] In some embodiments, the mounting port 112 is optionally located on the back of the housing 11. This eliminates the need for hoisting, simplifying the installation process and saving installation costs.
