Description

Technical Field

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

[0002] Current technologies for installing battery modules in energy storage devices have certain limitations. Most battery modules in current energy storage devices are installed using either hoisting or side mounting methods. Hoisting requires specialized hoisting tools and is complex, while side mounting lacks corresponding guiding structures. In actual installation, it is difficult to precisely align the battery modules with the enclosure, making installation extremely inconvenient and posing a risk of misalignment. Misalignment not only leads to unstable connections between the battery modules and the enclosure but may also cause collisions and friction between battery modules or between the battery modules and other components within the enclosure, thus affecting the normal operation and lifespan of the equipment.

[0003] Therefore, how to design a system that facilitates side mounting of battery modules while avoiding collisions and friction with the housing during side mounting is an urgent problem to be solved. Utility Model Content

[0004] This invention aims to at least solve the problems of inconvenient battery module installation and inability to accurately align the battery module with the fixed position of the housing.

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

[0006] The second aspect of this utility model provides an energy storage device.

[0007] In view of this, the first aspect of this utility model proposes an energy storage and charging pack, comprising: a housing having an installation port; a battery module detachably and slidably installed in the housing through the installation port; a guide component disposed in the housing, the guide component including a guide groove, the battery module being disposed in the guide groove and capable of sliding along the guide groove to a preset installation position; a limiting component disposed in the housing, located on the side of the battery module near the installation port, one end of the limiting component abutting against the battery module; and a cover plate covering the installation port for closing the installation port, the other end of the limiting component abutting against the cover plate, wherein when the cover plate closes the installation port, it can apply a force to the battery module along the sliding direction of the battery module through the limiting component.

[0008] The energy storage charging pack provided by this utility model effectively improves the installation efficiency and stability of the battery module by incorporating a guiding component and a limiting component. The guide groove of the guiding component provides a sliding path for the battery module, ensuring it can accurately slide to the preset installation position and avoiding misalignment. One end of the limiting component abuts against the battery module, and the other end abuts against the cover plate. When the cover plate closes the installation opening, the limiting component applies a force to the battery module, preventing it from shifting along the sliding direction, ensuring the stability of the battery module within the enclosure, and ensuring the reliability and safety of the energy storage device during operation.

[0009] In some embodiments, the guide assembly may optionally include a plurality of guide members that together form a guide groove, at least a portion of the structure of any guide member being disposed on a first side of the battery module, and at least a portion of the structure of any guide member being disposed on a second side of the battery module, wherein the first side and the second side are adjacent sides.

[0010] In these embodiments, the structural design of the guide assembly further enhances the installation accuracy and stability of the battery module. Multiple guide members form a guide groove, ensuring uniform force distribution during battery module sliding and reducing the risk of installation misalignment. The guide members are respectively positioned on adjacent sides of the battery module, providing multi-directional positioning support and reducing module swaying during sliding, thus improving installation efficiency. Furthermore, this design improves the compatibility between the battery module and the housing, ensuring that the battery module maintains a reasonable distance from other components within the housing after installation, avoiding collisions and friction, thereby further extending the service life of the energy storage device.

[0011] In some embodiments, optionally, the guide includes: a first guide having a first support portion and a first guide portion, the first support portion being disposed within the housing and located at the bottom of the battery module for supporting the battery module, and the first guide portion being connected to the first support portion and located on one side of the battery module for guiding the battery module when it slides; and a second guide having a second support portion and a second guide portion, the second support portion being disposed within the housing and located at the bottom of the battery module for supporting the battery module, and the second guide portion being connected to the second support portion and located on the other side of the battery module for guiding the battery module when it slides.

[0012] In these embodiments, by setting this dual guide structure, the battery module can be quickly aligned with the fixed position of the housing during installation. At the same time, the rigid constraint of the guide can prevent the module from twisting or tilting during sliding, thereby completely solving the misalignment problem caused by the lack of a guide structure in the traditional side mounting method, and ensuring the stability and reliability of the connection between the battery module 12 and the housing.

[0013] In some embodiments, optionally, the first support portion and the second support portion are both support plates, the first guide portion is a first bent portion formed by bending a portion of the support plate toward the direction of the battery module, and the second guide portion is a second bent portion formed by bending a portion of the support plate toward the direction of the battery module.

[0014] In these embodiments, by designing the first and second support portions of the guide assembly as support plates, and forming the guide portion by bending the support plates, the support and guidance are integrated, simplifying the structure and enhancing the overall strength. This design improves the load-bearing stability of the battery module, ensures precise guidance during sliding installation, effectively prevents misalignment, reduces manufacturing costs and assembly difficulty, improves production efficiency, and ensures the stable operation of the energy storage device.

[0015] In some embodiments, the guide may optionally further include: a third guide having a first guide body and a third guide portion, the first guide body being disposed within the housing and located at the top of the battery module, the third guide portion being connected to the first guide body and located on one side of the battery module, for guiding the battery module when it slides; and a fourth guide having a second guide body and a fourth guide portion, the second guide body being disposed within the housing and located at the top of the battery module, the fourth guide portion being connected to the second guide body and located on the other side of the battery module, for guiding the battery module when it slides.

[0016] In these embodiments, by incorporating a third and fourth guide member at the top, forming a coordinated top-to-bottom guiding system with the bottom guide member, the installation process of the battery module is further optimized. This design ensures that the battery module receives stable guidance from all directions during sliding, reducing the risk of installation misalignment and improving installation efficiency and equipment reliability. Simultaneously, the addition of the top guide member enhances the overall structural stability, reducing the risk of vibration and displacement of the battery module during operation, thereby extending the equipment's lifespan. Furthermore, this multi-directional guiding design improves the adaptability of the energy storage device to different battery module sizes and shapes, enhancing the device's versatility and flexibility.

[0017] In some embodiments, a preset distance may be provided between the first guide portion and the battery module, between the second guide portion and the battery module, between the third guide portion and the battery module, between the fourth guide portion and the battery module, between the first guide body and the battery module, and between the second guide body and the battery module.

[0018] In these embodiments, by setting a preset distance between the guide and the battery module, installation accuracy and efficiency are improved, and the risk of misalignment is reduced. Simultaneously, this design reduces the risk of collision and wear on the battery module during installation and operation, extending its service life; it also limits module sway and displacement, enhancing operational stability. Furthermore, the gap created by the preset distance facilitates airflow, optimizes heat dissipation, and provides better tolerance for dimensional tolerances of the battery module, improving the versatility and flexibility of the equipment. In summary, this design significantly improves the reliability, stability, and service life of energy storage devices.

[0019] In some embodiments, the preset distance is optionally greater than or equal to 2 mm and less than or equal to 5 mm.

[0020] In these embodiments, the preset distance between the guide and the battery module is set to be greater than or equal to 2mm and less than or equal to 5mm. This ensures that during installation and operation of the energy storage power pack, the battery module can be installed smoothly, avoiding excessive wear, while also ensuring the stability of the battery module after installation, reducing shaking and displacement, lowering the risk of loosening of connecting components, and guaranteeing stable operation of the equipment. At the same time, this distance range also takes into account the heat dissipation requirements of the battery module and the compatibility of modules of different sizes, improving the reliability and service life of the energy storage device.

[0021] In some embodiments, the energy storage charging pack may optionally include: a first elastic buffer disposed between the cover and the limiting assembly; and / or a second elastic buffer disposed between the side wall of the housing opposite to the mounting opening and the battery module.

[0022] In these embodiments, by incorporating a first elastic buffer and a second elastic buffer, the impact force during cover closure and the vibration and impact on the battery module during operation or transportation are effectively mitigated. This reduces collisions and wear between the battery module and the housing, lowers the risk of loosening of connecting components, and thus improves the operational stability and structural reliability of the energy storage device. Simultaneously, the elastic buffer allows for a certain degree of installation error, improving installation accuracy and convenience, and enhancing the adaptability and service life of the equipment under complex operating conditions.

[0023] 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 connectors disposed in the housing, with at least some connectors located inside the housing and at least some connectors located outside the housing, the connectors located inside the housing being used to connect to the circuit board and the connectors located outside the housing being used to connect to the energy storage host.

[0024] In these embodiments, the electrical connection between the battery module and the energy storage host is simplified by incorporating circuit boards and connectors. The circuit boards are located close to the cover for easy wiring and installation, while the connector design (partially inside the enclosure and partially outside) ensures connection stability and flexibility. This design not only improves the efficiency and reliability of the electrical connection but also facilitates maintenance and replacement, enhancing the overall performance and operability of the energy storage device.

[0025] The second aspect of this utility model provides an energy storage device, comprising: an energy storage host; and at least one energy storage power supply as described in any of the technical solutions of the first aspect, wherein the energy storage power supply is disposed at the bottom of the energy storage host.

[0026] The energy storage device provided by this utility model includes an energy storage host and at least one energy storage power supply pack as described in any of the technical solutions of the first aspect, with the energy storage power supply pack disposed at the bottom of the energy storage host. Since this energy storage device includes the energy storage power supply pack as described in any of the technical solutions of the first aspect, the energy storage device provided by this utility model also possesses all the beneficial effects of the energy storage power supply pack as described in any of the technical solutions of the first aspect, which will not be elaborated further here.

Detailed Implementation

[0037] 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.

[0038] 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.

[0039] The following reference Figures 1 to 6 This invention describes an energy storage power pack and energy storage device proposed according to some embodiments of the present invention.

[0040] 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 6As shown, the first aspect of this utility model provides an energy storage and charging pack 1, including a housing 11, a battery module 12, a guide assembly 13, a limiting assembly 14, and a cover plate 19. The housing 11 has a mounting opening 112, through which the battery module 12 is detachably slidably mounted within the housing 11. The guide assembly 13 is disposed within the housing 11 and includes a guide groove 131. The battery module 12 is disposed within the guide groove 131 and can slide along the guide groove 131 to a preset mounting position. The limiting assembly 14 is disposed within the housing 11, located on the side of the battery module 12 near the mounting opening 112, with one end of the limiting assembly 14 abutting against the battery module 12. The cover plate 19 is placed over the mounting opening 112 to close the mounting opening 112. The other end of the limiting component 14 abuts against the cover plate 19. When the cover plate 19 closes the mounting opening 112, it can apply a force to the battery module 12 along the sliding direction of the battery module 12 through the limiting component 14.

[0041] The energy storage power pack 1 provided by this utility model effectively improves the installation efficiency and stability of the battery module 12 by setting a guide component 13 and a limiting component 14 in the energy storage power pack. The guide groove 131 of the guide component 13 provides a sliding path for the battery module 12, ensuring that it can slide accurately to the preset installation position and avoid misalignment. One end of the limiting component 14 abuts against the battery module 12, and the other end abuts against the cover plate 19. When the cover plate 19 closes the installation opening 112, the limiting component 14 applies a force to the battery module 12 to prevent it from shifting along the sliding direction, ensuring the stability of the battery module 12 in the housing 11 and ensuring the reliability and safety of the energy storage device 10 during operation.

[0042] Specifically, the mounting port 112 can be located on the side of the housing 11, or more specifically, on the back of the housing 11, so that the battery module 12 can be installed into the housing 11 through the mounting port 112 on the back.

[0043] Among them, the guide component 13 can adopt a multi-guide structure. For example, two sets of guide rails can be installed in the housing 11 near the mounting port 112. Each set of guide rails consists of two symmetrically arranged guide components 132, forming a "U"-shaped guide groove. The two sides of the battery module 12 are embedded in the guide groove 131 and can slide along the long side of the guide rail.

[0044] In some embodiments, optionally, a sealing strip is provided at the connection between the cover plate 19 and the housing 11. Providing a sealing strip at the connection between the cover plate 19 and the housing 11 can ensure the airtightness of the interior of the housing 11.

[0045] In some embodiments, the cover plate 19 is optionally connected to the housing 11 by bolts. When the bolts are tightened, the cover plate 19 presses against the limiting component 14, so that the battery module 12 fits tightly against the housing 11.

[0046] In some embodiments, the guide assembly 13 may optionally include a plurality of guide members 132, which together form a guide groove 131. At least a portion of the structure of any guide member 132 is disposed on a first side of the battery module 12, and at least a portion of the structure of any guide member 132 is disposed on a second side of the battery module 12. The first side and the second side are adjacent sides.

[0047] In these embodiments, the structural design of the guide assembly 13 further enhances the installation accuracy and stability of the battery module 12. Multiple guide members 132 form a guide groove 131, ensuring uniform force distribution during the sliding of the battery module 12 and reducing the risk of installation misalignment. The guide members 132 are respectively positioned on adjacent sides of the battery module 12, providing multi-directional positioning support for the module and reducing swaying during sliding, thus improving installation efficiency. Furthermore, this design improves the compatibility between the battery module 12 and the housing 11, ensuring that the battery module 12 maintains a reasonable distance from other components within the housing 11 after installation, avoiding collisions and friction, thereby further extending the service life of the energy storage device 10.

[0048] In some embodiments, optionally, two guide members 132 are provided, and they are L-shaped, respectively disposed on the left and right sides of the battery module 12. The horizontal and vertical portions of each L-shaped guide member are respectively disposed on adjacent sides of the battery module 12. For example, the horizontal portion of the left guide member 132 is disposed on the bottom side of the battery module 12, and the vertical portion is disposed on the left side of the battery module 12. The horizontal portion of the right guide member 132 is disposed on the bottom side of the battery module 12, and the vertical portion is disposed on the right side of the battery module 12. The horizontal and vertical portions of the two L-shaped guide members together form a U-shaped guide groove 131. The size of the guide groove 131 is adapted to the shape of the battery module 12 to ensure that the battery module 12 can slide accurately into and move along the guide groove 131.

[0049] Furthermore, the guide component 132 is made of a single piece of metal, which has high strength and rigidity. The inner surface of the guide groove 131 is smooth, which reduces the friction when the battery module 12 slides and improves the smoothness of sliding.

[0050] During installation, align the battery module 12 with the entrance of the guide groove 131, and then smoothly push the battery module 12 along the direction of the guide groove 131 to slide it into the housing 11. The symmetrical L-shaped guides ensure that the battery module 12 receives a uniform guiding force during sliding, avoiding module offset and shaking, and ensuring the stability and accuracy of installation.

[0051] In some embodiments, the guide assembly 13 optionally comprises four guide members 132, namely a lower left guide member, a lower right guide member, an upper left guide member, and an upper right guide member. The lower left guide member is disposed on the left and bottom sides of the battery module 12, the lower right guide member is disposed on the right and bottom sides of the battery module 12, the upper left guide member is disposed on the left and top sides of the battery module 12, and the upper right guide member is disposed on the right and top sides of the battery module 12. The four guide members 132 together form a rectangular guide groove 131, the size of which matches the shape of the battery module 12 to ensure that the battery module 12 can slide smoothly into and move along the guide groove 131.

[0052] Furthermore, all four guide components 132 are L-shaped guide components.

[0053] In some embodiments, optionally, the guide member 132 includes: a first guide member 133, the first guide member 133 having a first support portion 1332 and a first guide portion 1334, the first support portion 1332 being disposed inside the housing 11 and located at the bottom of the battery module 12 for supporting the battery module 12, the first guide portion 1334 being connected to the first support portion 1332 and located on one side of the battery module 12 for guiding the battery module 12 when it slides; and a second guide member 134, the second guide member 134 having a second support portion 1342 and a second guide portion 1344, the second support portion 1342 being disposed inside the housing 11 and located at the bottom of the battery module 12 for supporting the battery module 12, the second guide portion 1344 being connected to the second support portion 1342 and located on the other side of the battery module 12 for guiding the battery module 12 when it slides.

[0054] In these embodiments, the first bearing portion 1332 of the first guide member 133 is located at the bottom of the housing 11, directly bearing the weight of the battery module 12 and providing a stable support foundation for the module. Its first guide portion 1334 is located on one side of the battery module 12, forming a rigid constraint during module sliding to ensure that the battery module 12 moves along a preset trajectory and avoids deviation. The second bearing portion 1342 of the second guide member 134 works in conjunction with the first bearing portion 1332 to share the load of the battery module 12, enhancing the reliability of the support. The second guide portion 1344 is located on the other side of the module, forming a symmetrical guide structure with the first guide portion 1334, constituting a complete guide groove 131. This symmetrical design ensures balanced force distribution on the module during sliding, effectively reducing swaying and improving installation accuracy.

[0055] By setting this dual-guide structure, the battery module 12 can be quickly aligned with the fixed position of the housing 11 during installation. At the same time, the rigid constraint of the guide can prevent the module from twisting or tilting during sliding, thereby completely solving the misalignment problem caused by the lack of a guide structure in the traditional side-mounting method, and ensuring the stability and reliability of the connection between the battery module 12 and the housing.

[0056] Specifically, the first support portion 1332 can be a horizontally placed support plate 137, which is fixedly installed at the bottom of the housing 11 to support the battery module 12. The first guide portion 1334 is a first bend portion 1336 formed by bending the support plate 137 vertically in the direction of the battery module 12, located on the left side of the battery module 12, and is used to guide the battery module 12 when it slides.

[0057] The second support portion 1342 is also a horizontally placed support plate 137, which is fixedly installed at the bottom of the housing 11 to support the battery module 12. The second guide portion 1344 is a second bend portion 1346 formed by bending the support plate 137 vertically in the direction of the battery module 12, located on the right side of the battery module 12, and is used to guide the battery module 12 when it slides.

[0058] In some embodiments, optionally, the first support portion 1332 and the second support portion 1342 are both support plates 137, the first guide portion 1334 is a first bending portion 1336 formed by bending a portion of the support plate 137 toward the direction of the battery module 12; the second guide portion 1344 is a second bending portion 1346 formed by bending a portion of the support plate 137 toward the direction of the battery module 12.

[0059] In these embodiments, by designing the first support portion 1332 and the second support portion 1342 of the guide assembly 13 as a support plate 137, and forming the guide portion by bending the support plate 137, the support and guidance are integrated, simplifying the structure and enhancing the overall strength. This design improves the load-bearing stability of the battery module 12, ensures its precise guidance during sliding installation, effectively prevents misalignment, reduces manufacturing costs and assembly difficulty, improves production efficiency, and ensures the stable operation of the energy storage device 10.

[0060] In some embodiments, the guide 132 may be a stamped part.

[0061] In some embodiments, the guide member 132 may optionally include: a third guide member 135, the third guide member 135 having a first guide body 1352 and a third guide portion 1354, the first guide body 1352 being disposed inside the housing 11 and located at the top of the battery module 12, the third guide portion 1354 being connected to the first guide body 1352 and located on one side of the battery module 12, for guiding the battery module 12 when it slides; and a fourth guide member 136, the fourth guide member 136 having a second guide body 1362 and a fourth guide portion 1364, the second guide body 1362 being disposed inside the housing 11 and located at the top of the battery module 12, the fourth guide portion 1364 being connected to the second guide body 1362 and located on the other side of the battery module 12, for guiding the battery module 12 when it slides.

[0062] In these embodiments, the installation process of the battery module 12 is further optimized by providing a third guide 135 and a fourth guide 136 at the top, forming a coordinated top-to-bottom guiding system with the bottom guide. This design ensures that the battery module 12 is stably guided from all directions during sliding, reducing the risk of installation misalignment and improving installation efficiency and equipment reliability. Simultaneously, the addition of the top guide enhances the stability of the overall structure, reducing the risk of vibration and displacement of the battery module 12 during operation, thereby extending the service life of the equipment. Furthermore, this multi-directional guiding design improves the adaptability of the energy storage device 10 to different battery module 12 sizes and shapes, enhancing the device's versatility and flexibility.

[0063] Since both the first guide body 1352 and the second guide body 1362 are located at the top of the housing 11, the first guide body 1352 and the second guide body 1362 can also be used to limit the battery module 12 in the vertical direction.

[0064] In some embodiments, optionally, a preset distance is provided between the first guide portion 1334 and the battery module 12, between the second guide portion 1344 and the battery module 12, between the third guide portion 1354 and the battery module 12, between the fourth guide portion 1364 and the battery module 12, between the first guide body 1352 and the battery module 12, and between the second guide body 1362 and the battery module 12.

[0065] In these embodiments, by setting a preset distance between the guide and the battery module 12, installation accuracy and efficiency are improved, and the risk of misalignment is reduced. Simultaneously, this design reduces the risk of collision and wear on the battery module 12 during installation and operation, extending its service life; it also limits the module's swaying and displacement, enhancing operational stability. Furthermore, the gap created by the preset distance facilitates airflow, optimizes heat dissipation, and provides better tolerance for the dimensional tolerances of the battery module 12, improving the device's versatility and flexibility. In summary, this design significantly improves the reliability, stability, and service life of the energy storage device 10.

[0066] In some embodiments, the preset distance is optionally greater than or equal to 2 mm and less than or equal to 5 mm.

[0067] In these embodiments, the preset distance between the guide member 132 and the battery module 12 is set to be greater than or equal to 2 mm and less than or equal to 5 mm. This ensures that during installation and operation of the energy storage power pack 1, the battery module 12 can be installed smoothly, avoiding excessive wear, while also ensuring the stability of the battery module 12 after installation, reducing shaking and displacement, lowering the risk of loosening of connecting components, and guaranteeing stable operation of the equipment. At the same time, this distance range also takes into account the heat dissipation requirements of the battery module 12 and the compatibility of modules of different sizes, improving the reliability and service life of the energy storage device 10.

[0068] In some embodiments, the preset distance is optionally 2mm.

[0069] In some embodiments, the preset distance is optionally 3mm.

[0070] In some embodiments, the preset distance is optionally 4mm.

[0071] In some embodiments, the preset distance is optionally 5mm.

[0072] In some embodiments, the energy storage charging pack 1 may optionally include: a first elastic buffer 15 disposed between the cover plate 19 and the limiting component 14; and / or a second elastic buffer 16 disposed between the side wall of the housing 11 opposite to the mounting port 112 and the battery module 12.

[0073] In these embodiments, by providing a first elastic buffer 15 and a second elastic buffer 16, the impact force when the cover 19 closes and the vibration and impact of the battery module 12 during operation or transportation are effectively mitigated. This reduces collisions and wear between the battery module 12 and the housing 11, lowers the risk of loosening of connecting components, and thus improves the operational stability and structural reliability of the energy storage device 10. Simultaneously, the elastic buffers allow for a certain installation error, improving installation accuracy and convenience, and enhancing the adaptability and service life of the equipment under complex operating conditions.

[0074] In some embodiments, the first elastic buffer 15 or the second elastic buffer 16 may optionally include at least one or a combination of the following: foam, rubber, polyurethane foam and plastic.

[0075] 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 component 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 10, facilitating installation and handling, while their corrosion resistance and durability ensure the long-term stable performance of the elastic buffer components under different environments, reducing maintenance costs and improving the reliability and economy of the energy storage system.

[0076] Specifically, the first elastic buffer 15 is disposed between the cover plate 19 and the limiting component 14, and is made of foam. When the cover plate 19 is closed, the foam is compressed, producing elastic deformation, absorbing the impact force, preventing the battery module 12 from being subjected to excessive pressure, and ensuring the stability of the battery module 12 after installation.

[0077] During installation, first, place the second elastic buffer 16 into the housing 11. Then, align the bottom edges of the battery module 12 with the entrance of the guide groove 131. Push the battery module 12 along the guide groove 131 to allow it to slide smoothly into the housing 11. Next, place the limiting component 14 into the housing 11 to abut against the battery module 12, and attach the first elastic buffer 15 to the limiting component 14. Finally, install the cover plate 19, which presses against the limiting component 14. The first elastic buffer 15 provides cushioning during the closing of the cover plate 19, ensuring a tight fit between the battery module 12 and the housing 11, while reducing the impact force during installation.

[0078] In some embodiments, the energy storage power pack 1 may optionally include: a circuit board 18 disposed on the side of the battery module 12 near the cover plate 19; and a connector 17 disposed on the housing 11, with at least some of the connectors 17 located inside the housing 11 and at least some of the connectors 17 located outside the housing 11. The portion of the connectors 17 located inside the housing 11 is used to connect to the circuit board 18, and the portion of the connectors 17 located outside the housing 11 is used to connect to the energy storage host 2.

[0079] In these embodiments, the circuit board 18 is mounted on the side of the battery module 12 near the cover plate 19. This arrangement creates a compact integrated layer between the battery module 12 and the cover plate 19. The main function of the circuit board 18 is to enable electrical connection and signal transmission between the battery module 12 and external devices (such as the energy storage host 2). It is responsible for the distribution and conversion of electrical energy and monitoring the operating status of the battery module 12. Of course, the circuit board 18 may also have other functions, which are not limited here.

[0080] Specifically, the circuit board 18 can be fixed on the side of the battery module 12 near the cover plate 19 to ensure the stability of the circuit board 18 installation.

[0081] By incorporating circuit board 18 and connector 17, the electrical connection between battery module 12 and energy storage host 2 is simplified. Circuit board 18 is located near cover plate 19 for easy wiring and installation, while the design of connector 17 (partially inside and partially outside the housing 11) ensures connection stability and flexibility. This design not only improves the efficiency and reliability of the electrical connection but also facilitates maintenance and replacement, enhancing the overall performance and operability of energy storage device 10.

[0082] In some embodiments, the circuit board 18 may be a BMS (Battery Management System) board.
