The center of gravity of the battery module is significantly offset from the center of the energy storage power supply. Energy storage power supplies with this structure are prone to vibration coupling effects during operation, reducing the stability of the energy storage power supply, thereby increasing the risk of mechanical fatigue and shortening the energy storage power supply's service life.

[0023] With the advancement of science and technology, energy storage technology has flourished, and the structure of energy storage power supplies needs to be further optimized to meet the increasingly stringent requirements of the market. At present, in energy storage power supplies, battery modules are usually locked to the front shell in a side-mounted manner. The center of gravity of the battery module will seriously deviate from the center of the energy storage power supply. Energy storage power supplies with this structure are prone to vibration coupling effects during operation, reducing the stability of the energy storage power supply, thereby increasing the risk of mechanical fatigue of the energy storage power supply and shortening the service life of the energy storage power supply. In order to solve this problem, the present application provides an energy storage power supply ( Figure 1 as shown) and the assembly method of the energy storage power supply.

[0024] See also Figures 1 to 4 The energy storage power supply 100 provided in the embodiment of the present application includes a housing 10, a battery module 30, a locking member, and a support member 50. The housing 10 includes a first shell 11 and a second shell 13, which together form a housing cavity 15. The first shell 11 includes a top wall 111 and a peripheral side wall 113, which extends from the periphery of the top wall 111. The battery module 30 is accommodated in the housing cavity 15. The battery module 30 includes a first end 301 and a second end 302 opposite to each other. The first end 301 of the battery module is locked to the top wall 111 by a locking member (not shown), and the second end 302 of the battery module is opposite to the second shell 13. The locking member connects the battery module 30 and the top wall 111 to lock the battery module 30 to the top wall 111. The support member 50 connects the battery module 30 and the peripheral side wall 113 to support the battery module 30 against the top wall 111.

[0025] In the above-described embodiments, the energy storage power supply 100 is a device for storing and releasing energy. In some embodiments, the energy storage power supply 100 can be a large-capacity, high-power, and multifunctional portable energy storage device that can be used in both off-grid microgrid systems and networked power grid systems. When used in an off-grid microgrid system, the energy storage power supply 100 can replace traditional fuel-fired generators, providing clean energy for the loads in the off-grid microgrid system. When used in a networked power grid system, in addition to providing power to the loads on the grid, the energy storage power supply 100 can also provide power to the utility grid during periods of high electricity prices, when there is still surplus power after supplying power to the loads. Of course, the energy storage power supply 100 can also be used in scenarios such as outdoor camping, emergency rescue, and professional work (such as photography and engineering), meeting the power needs of areas without a grid or with unstable power supply.

[0026] The housing 10 is a structure used to protect, house, and / or install functional components of the energy storage power supply 100, such as the battery module 30. The housing 10 can be made of, but is not limited to, metal or plastic. Metal offers high structural strength, is resistant to damage, and has a long service life. Plastic offers low weight, portability, and a low cost. In some embodiments, the housing 10 is a split-body structure to facilitate the installation of functional components such as the battery module 30 within the housing 10. Specifically, the housing 10 includes a first shell 11 and a second shell 13, each of which is a split-body structure. The first shell 11 and the second shell 13 can be made of the same or different materials. The first shell 11 and the second shell 13 are connected to each other after being formed. The connection between the first shell 11 and the second shell 13 can be detachable or non-detachable. Removable connections include, but are not limited to, screw connections and snap-on connections, or a combination thereof. Non-detachable connections include, but are not limited to, gluing, welding, and sintering. The following definitions of "detachable and / or non-detachable connection" will be applied and will not be further elaborated. The first shell 11 and the second shell 13 are interconnected to form a housing cavity 15. The housing cavity 15 is a spatial structure for accommodating and mounting functional components such as the battery module 30. The battery module 30 and other functional components are housed within the housing cavity 15 through connection with the first shell 11 and / or the second shell 13 and are fixed relative to the housing cavity 15 to stabilize the structure of the energy storage power supply 100.

[0027] The first shell 11 is the part of the shell 10 used to connect with the battery module 30. The top wall 111 is the side wall of the first shell 11 at one end away from the second shell 13. The peripheral side wall 113 is a side wall extending from the peripheral edge of the top wall 111. The top wall 111 and the peripheral side wall 113 can be integrally formed or separately formed. In the case where the top wall 111 and the peripheral side wall 113 are integrally formed, the strength of the first shell 11 is higher. In the case where the top wall 111 and the peripheral side wall 113 are separately formed, the top wall 111 and the peripheral side wall 113 can be detachably connected or non-detachably connected. At this time, the manufacturing molds of the top wall 111 and the peripheral side wall 113 are smaller, and the overall processing process of the first shell 11 is simpler.

[0028] The second shell 13 is the portion of the housing 10 that connects to the first shell 11, providing the housing 10 with a certain degree of strength as a single unit. The sidewall 113 of the first shell 11 has an opening on the side away from the top wall 111, and the size of the second shell 13 matches the size of the opening. Therefore, the second shell 13 can be installed in the opening of the sidewall 113 of the first shell 11. In this case, the second shell 13 can be connected to the sidewall 113 of the first shell 11 by welding, snapping, gluing, or a combination of one or more methods to seal the accommodating cavity 15.

[0029] The battery module 30 is the core module of the energy storage power supply 100, responsible for storing and releasing electrical energy. Based on the different application scenarios of the energy storage power supply 100, the energy storage power supply 100 has different capacities, and therefore, the battery module 30 has different capacities. For example, in a small household or commercial energy storage power supply 100, the capacity of the battery module 30 typically ranges from a few kilowatt-hours to tens of kilowatt-hours. The battery module 30 is housed in the accommodating cavity 15 and can be electrically connected to other functional components.

[0030] The battery module 30 includes a first end 301 and a second end 302, wherein the first end 301 corresponds to the top wall 111 of the first shell 11, and the second end 302 corresponds to the second shell 13. The first end 301 of the battery module is connected to the top wall 111 to achieve connection between the battery module 30 and the first shell 11. Specifically, the energy storage power supply 100 includes a locking member for locking the first end 301 of the battery module to the top wall 111. The position of the battery module 30 within the accommodating cavity 15 can be adjusted by adjusting the position of the first end 301 and the top wall 111 in conjunction with the locking member. In other words, the position of the center of gravity of the battery module 30 relative to the accommodating cavity 15 can be adjusted. The optimal position of the center of gravity of the battery module 30 is at the center of the energy storage power supply 100, where the overall center of gravity of the energy storage power supply 100 is most stable.

[0031] In some embodiments, the locking member is a screw. In this case, the top wall 111 needs to have a threaded structure that mates with the locking member. In other embodiments, the locking member is a snap-fit structure (not a screw) that nests with the first end 301 of the battery module and the top wall 111. In this case, the first end 301 of the battery module and the top wall 111 can be locked together by snap-fitting, or by snap-fitting combined with welding or gluing. The second end 302 of the battery module opposes the second shell 13, and no connecting structure is provided between them. In this case, the area between the second end 302 of the battery module and the second shell 13 can be used to accommodate other components or reserved as a heat dissipation area for the battery module 30.

[0032] In the energy storage power supply 100 of the present application, the battery module 30 is locked to the top wall 111 of the first shell 11 by a locking member so that the battery module 30 is accommodated in the accommodating cavity 15. At the same time, the energy storage power supply 100 also supports the battery module 30 by a support member 50 so that the battery module 30 is against the top wall 111, which further strengthens the installation of the battery module 30. Compared with the energy storage power supply in which the battery module is placed on its side and locked to the front shell, the center of gravity of the battery module 30 in the energy storage power supply 100 of the present application can be close to the center of the energy storage power supply 100. The energy storage power supply 100 will not induce a vibration coupling effect during operation, which can improve the stability of the energy storage power supply 100, thereby reducing the risk of mechanical fatigue of the energy storage power supply 100. In addition, the structural strength of the energy storage power supply 100 is relatively large, thereby extending the service life of the energy storage power supply 100.

[0033] When the battery module 30 is mounted on the top wall 111 by means of a locking member, if it is not connected to the peripheral side wall 113, the battery module 30 may shake during transportation of the energy storage power supply 100. This shaking may in turn shake the bonding strength between the first end 301 of the battery module and the top wall 111. Over long-term use, the battery module 30 may fall off the shell 10 and explode or catch fire, resulting in insufficient safety of the energy storage power supply 100. Therefore, the energy storage power supply 100 of the present application further strengthens the bonding strength between the battery module 30 and the first shell 11 by providing at least one support member 50. The support member 50 can be provided between any one or more sides of the peripheral side wall 113 and any one or more sides of the corresponding battery module 30. The greater the number of support members 50, the more secure the bonding between the battery module 30 and the first shell 11.

[0034] Please refer to Figure 4 The support member 50 is used to connect the battery module 30 to the peripheral sidewall 113 of the first shell 11. In some embodiments, there may be at least one support member 50, for example, one, two, three, or more. The support member 50 is disposed within the accommodating cavity 15 and connects the peripheral sidewall 113 to the second end 302 of the battery module (specifically, the end surface of the second end 302 of the battery module).

[0035] The dimensions of the support member 50 must be compatible with the distance between the battery module 30 and the peripheral sidewall 113. Specifically, the support member 50 can be a flat plate structure or a curved structure with a curved portion and a flat plate portion. A flat plate structure provides a simple structure and low cost. A curved structure allows for the support member 50 to make room for other components within the accommodating cavity 15, enhancing the internal layout and component installation flexibility of the energy storage power supply 100. The support member 50 connects the peripheral sidewall 113 of the first shell 11 and the end surface of the second end 302 of the battery module, providing support for the battery module 30. The support force exerted by the support member 50 on the battery module 30 is sufficient to hold the battery module 30 against the top wall 111. Therefore, the battery module 30 is not only bonded to the top wall 111 at the first end 301, but also bonded to the peripheral sidewall 113 at the second end 302 through the support member 50, enhancing the structural stability of the energy storage power supply 100.

[0036] Please refer to Figure 2 and Figure 3 In some embodiments, the battery module 30 includes a first bracket 31, a second bracket 33 and a battery cell assembly 37. The first bracket 31 is provided with a first coupling member 311 and a plurality of first plug-in holes. The second bracket 33 is provided with a second coupling member 331 and a plurality of second plug-in holes. The first coupling member 311 and the second coupling member 331 are plugged into each other so that the second bracket 33 is connected to the first bracket 31 relative to the first bracket 31. A mounting groove 35 is formed between the first bracket 31 and the second bracket 33. The battery cell assembly 37 includes a plurality of battery cells 371. The battery cell assembly 37 is arranged in the mounting groove 35, and one end of the plurality of battery cells 371 is plugged into the first plug-in hole and the other end is plugged into the second plug-in hole.

[0037] Specifically, the cell assembly 37 is the core component of the battery module 30 for storing and releasing electrical energy. Specifically, the cell assembly 37 includes at least one cell 371. A cell 371 is the smallest unit for storing and releasing electrical energy. The battery module 30 achieves energy storage and release by connecting and controlling the operating state of the cell 371. Each cell 371 includes a first electrode and a second electrode of opposite polarity. The electrode corresponding to the first end 301 of the battery module is defined as the first electrode, and the electrode corresponding to the second end 302 of the battery module is defined as the second electrode. When the first electrode is positive, the second electrode is negative; when the first electrode is negative, the second electrode is positive. Multiple cells 371 can be connected in series, in parallel, or in a mixed connection (in this application, "multiple" means more than one, and "multiple" can be, but is not limited to, two, three, or four). Mixed connection means that multiple cells 371 are connected in both series and parallel. Multiple battery cells 371 can be directly connected in series, in parallel, or in a mixed manner to form a battery cell assembly 37 to implement the charging and discharging functions of the energy storage power supply 100. Therefore, the safety of the battery cell assembly 37 directly affects the safety and service life of the energy storage power supply 100. It is understood that the number of battery cells 371 in the battery cell assembly 37 can be adaptively adjusted according to the application scenario and capacity.

[0038] After the energy storage power supply 100 is processed, the energy storage power supply 100 may be transported and / or used. When the energy storage power supply 100 is transported, the battery cell assembly 37 in the battery module 30 may be subjected to squeezing force when the energy storage power supply 100 is moved. When the energy storage power supply 100 is used, the battery cell assembly 37 in the battery module 30 will undergo charging and / or discharging. Charging and / or discharging will generate heat and increase the internal temperature of the energy storage power supply 100. When the energy storage power supply 100 stops working, the internal temperature of the energy storage power supply 100 will drop again and approach normal temperature. The rise and fall of the internal temperature of the energy storage power supply 100 will cause thermal expansion and contraction, and thermal expansion and contraction will also cause the battery cell assembly 37 to be subjected to squeezing force. Any of the above squeezing forces will cause the battery cell 371 to have the risk of explosion.

[0039] The battery module 30 of the energy storage power supply 100 of the present application is installed and protected by a first bracket 31 and a second bracket 33 for the battery cell assembly 37. The first bracket 31 is a structure for supporting and limiting the battery cell assembly 37. In the direction from the first end 301 of the battery module to the second end 302 of the battery module, the first bracket 31 also includes two opposite ends, namely the first end 3101 of the first bracket and the second end 3102 of the first bracket, wherein the first end 3101 of the first bracket is located at the same end as the first end 301 of the battery module, and the second end 3102 of the first bracket is located at the same end as the second end 302 of the battery module. In some examples, the first bracket 31 may include a bottom plate disposed at the second end 3102 of the first bracket and a limiting portion extending from the bottom plate toward the first end 3101 of the first bracket, wherein the limiting portion and the bottom plate enclose a limiting space. The base plate is provided with a plurality of first insertion holes for limiting the installation position of the battery cells 371. The size and number of the first insertion holes correspond to the size and number of the battery cells 371, so that any battery cell 371 can be at least partially accommodated in a first insertion hole. All battery cells 371 are accommodated within the limited space and are restrained by the surrounding limiting parts. Therefore, the cooperation between the battery cells 371 and the first insertion holes allows the battery cell assembly 37 to be accurately installed on the first bracket 31.

[0040] The second bracket 33 is a structure that covers the first bracket 31 and further limits the battery cell assembly 37. The second bracket 33 is roughly flat and is provided with a plurality of second plug-in holes. The size and number of the second plug-in holes correspond to the size and number of the battery cells 371, respectively, so that any battery cell 371 can be at least partially accommodated in the second plug-in holes. Specifically, the second bracket 33 can cover the first bracket 31 at the first end 3101 of the first bracket, so that the second bracket 33 can cooperate with the first bracket 31 to form a mounting groove 35. At this time, the spatial structure between the first bracket 31 and the second bracket 33 is the mounting groove 35. The mounting groove 35 includes at least a portion of the first plug-in hole and at least a portion of the second plug-in hole. The battery cell assembly 37 is arranged in the mounting groove 35, that is, the battery cell assembly 37 is clamped between the first bracket 31 and the second bracket 33. Therefore, after one end of the battery cell 371 in the battery cell assembly 37 is installed on the first bracket 31 and limited by the first plug-in hole, the second bracket 33 covers the first bracket 31, and the other end of the battery cell 371 in the battery cell assembly 37 is limited by the second plug-in hole, thereby realizing the connection of the first bracket 31, the battery cell assembly 37 and the second bracket 33 to form a battery module 30 with an integral structure.

[0041] The first bracket 31 and the second bracket 33 can be made of the same material or different materials. Specifically, the material of the first bracket 31 and / or the second bracket 33 can be, but is not limited to, metal and plastic. When the first bracket 31 and / or the second bracket 33 are made of metal, the first bracket 31 and / or the second bracket 33 have high structural strength, are not easily damaged, and have a long service life. When the first bracket 31 and / or the second bracket 33 are made of plastic, the battery module 30 has the advantages of being lightweight and low in cost. In addition, at least part of the first bracket 31 and the second bracket 33 is made of an insulating material to ensure the safety of the battery module 30.

[0042] In order to simplify the installation process of the battery module 30 while ensuring the stability of the battery module 30, the first bracket 31 is provided with a first coupling member 311, and the second bracket 33 is provided with a second coupling member 331. The insertion of the first coupling member 311 and the second coupling member 331 realizes the relative connection between the first bracket 31 and the second bracket 33. In some embodiments, the first coupling member 311 is a snap-fitting hole, and the second coupling member 331 is a deformable hook. The hook has two states: an initial state and a deformed state. The hook passes through the snap-fitting hole in a deformed state. After the hook returns to its initial state, the hook-shaped structure of the hook can interfere with the periphery of the snap-fitting hole to realize the snap-fitting between the snap-fitting hole and the hook, thereby making the first bracket 31 and the second bracket 33 relatively connected. In other embodiments, the first coupling member 311 is a deformable hook, and the second coupling member 331 is a snap-fitting hole, such as Figure 2 As shown. The hook passes through the engaging hole in a deformed state, and after the hook returns to its initial state, the hook-shaped structure of the hook can interfere with the periphery of the engaging hole to achieve the engaging of the engaging hole and the hook, thereby making the first bracket 31 and the second bracket 33 relatively connected. Regardless of which of the above-mentioned embodiments is used, a precision engaging connection is adopted between the first bracket 31 and the second bracket 33 to achieve fast, accurate positioning and tight connection between the first bracket 31 and the second bracket 33. At the same time, the precision engaging connection between the first bracket 31 and the second bracket 33 replaces the traditional threaded connection, which can reduce the cost of purchasing screws and the assembly process. According to calculations, compared with the threaded connection method, the engaging connection method of the present application shortens the assembly time of a single energy storage power supply 100 by more than 30%, and reduces the production cost of the energy storage power supply 100 by 25%, effectively improving the market competitiveness of the energy storage power supply 100 of the present application.

[0043] In the energy storage power supply 100 of the present application, the battery cell assembly 37 is arranged in the installation groove 35 surrounded by the first bracket 31 and the second bracket 33, and the first coupling member 311 is plugged into the second coupling member 331, so that the first bracket 31, the battery cell assembly 37 and the second bracket 33 can be connected to form a battery module 30 with an integral structure. The battery module 30 with an integral structure is locked and combined with the first shell 11 by a locking member. This assembly method can effectively disperse the extrusion force on the battery cell assembly 37 during the transportation and / or use of the energy storage power supply 100, thereby reducing the risk of explosion of the battery cell assembly 37 and improving the usability and installation of the energy storage power supply 100.

[0044] Please refer to Figure 2 and Figure 3 In some embodiments, the battery module 30 further includes a first electrical connection component 38 and a second electrical connection component 39. The first electrical connection component 38 is disposed on a side of the first bracket 31 away from the first plug hole, and includes a plurality of first electrical connectors 381, which are welded to the first pole of the battery cell 371. The second electrical connection component 39 is disposed on a side of the second bracket 33 away from the second plug hole, and includes a plurality of second electrical connectors 391, which are welded to the second pole of the battery cell 371. The polarity of the second pole is opposite to that of the first pole. The first bracket 31 is provided with an isolating member 317, which is disposed around the first electrical connector 381.

[0045] Since the battery cell assembly 37 includes multiple battery cells 371, and the total current of the battery cell assembly 37 is the total current of the multiple battery cells 371 after being connected in series, in parallel, or in mixed connection, the battery module 30 also needs to be provided with a structure for collecting the currents of the individual battery cells 371. Specifically, in the above embodiment, the battery module 30 may also include a first electrical connection assembly 38 and a second electrical connection assembly 39 for current collection. The first electrical connection assembly 38 is a component for realizing electrical connection between the first poles of the multiple battery cells 371. The first electrical connection assembly 38 includes multiple first electrical connectors 381 and is arranged on the second side 3102 of the first bracket. The second electrical connection assembly 39 is a component for realizing electrical connection between the second poles of the multiple battery cells 371. The second electrical connection assembly 39 includes multiple second electrical connectors 391 and is arranged between the second bracket 33 and the top wall 111. The number of the first electrical connectors 381 matches the number of the battery cells 371 , and the number of the second electrical connectors 391 matches the number of the battery cells 371 , so as to achieve the function of converging the currents of all the battery cells 371 .

[0046] The number of the second electrical connectors 391 matches the number of the battery cells 371. The first electrical connector 381 and / or the second electrical connector 391 are both made of conductive materials. Specifically, the first electrical connector 381 and / or the second electrical connector 391 can be an aluminum bar. In this case, the first electrical connector 381 and / or the second electrical connector 391 have a better current collection effect and a lower cost. After the battery cell assembly 37 is installed in the installation slot 35 and accurately positioned relative to the first bracket 31 and the second bracket 33, the first electrical connector assembly 38 is welded to the first pole of the battery cell 371, and the second electrical connector assembly 39 is welded to the second pole of the battery cell 371 to achieve series connection, parallel connection or mixed connection of multiple battery cells 371. Therefore, the energy storage power supply 100 of the present application can achieve the collection and distribution of current between each battery cell 371 by setting the first electrical connector assembly 38 and the second electrical connector assembly 39, thereby ensuring the efficient and safe operation of the battery module 30.

[0047] Please refer to further Figure 3 , wherein the isolating member 317 is a structure for preventing an electrical short circuit from occurring due to incorrect connection of electrodes between multiple battery cells 371. Specifically, the isolating member 317 is a raised structure formed by the end surface of the second end 3102 of the first bracket protruding toward the second shell 13. The isolating member 317 and the first bracket 31 can be separately formed or integrally formed. In the case where the isolating member 317 and the first bracket 31 are separately formed, the isolating member 317 and the first bracket 31 can be detachably connected or non-detachably connected. The material of the isolating member 317 can be the same as or different from the material of the first bracket 31, and the material of the isolating member 317 is also an insulating material.

[0048] At least two isolators 317 form a group and are arranged on the periphery of the first electrical connector 381 to shield at least part of the outer edge of the first electrical connector 381. At this time, the isolators 317 can limit the contact between foreign matter and the first electrical connector 381, thereby playing an isolating role. At the same time, the isolators 317 can also play a role in limiting the position of the first electrical connector 381, making the installation and positioning of the first electrical connector 381 simple. Therefore, in the event of a screw falling or conductive debris entering, the isolators 317 can effectively prevent the screws and conductive debris from approaching the first electrical connector 381 and the electrode, thereby effectively preventing the occurrence of an electrical short circuit, thereby further improving the reliability of the energy storage power supply 100.

[0049] Additionally, in some embodiments, the number of isolators 317 is the same as the number of first electrical connectors 381. In this case, each first electrical connector 381 is surrounded by isolators 317, which maximizes isolation. In other embodiments, the number of isolators 317 is less than the number of first electrical connectors 381. In this case, isolators 317 are only provided around the first electrical connectors 381 near the periphery of the first bracket 31, while isolators 317 are not provided around the first electrical connectors 381 near the center of the first bracket 31. This ensures isolation while reducing costs.

[0050] Please refer to Figure 6 and Figure 7 In some embodiments, the inner side surface of the top wall 111 located within the accommodating cavity 15 is provided with a first mounting hole 1111. The first bracket 31 includes a first end 3101 and a second end 3102 opposite each other. The second bracket 33 is provided with a through-hole 333 extending therethrough. A connecting post 313 is provided at the first end 3101 of the first bracket. The connecting post 313 is provided with a second mounting hole 3131 and extends through the through-hole 333. A locking member is provided through the second mounting hole 3131 and is locked to the first mounting hole 1111.

[0051] The front shell of current energy storage power supplies is equipped with a connection structure formed by a bead-in process. This connection structure mates with the connection holes in the battery module to secure the battery module and the front shell. However, during the injection molding of the connection structure onto the front shell, the complex interaction between the shrinkage stress of the injection molding material and the injection pressure can easily lead to stress concentration at the connection structure, resulting in a high risk of cracking in the connection structure and / or the front shell, affecting the product quality and reliability of the energy storage power supply. To address this issue, the energy storage power supply 100 of the present application incorporates a separate locking element during the connection process between the battery module 30 and the housing 10, thereby eliminating the bead-in process step during the processing of the energy storage power supply 100.

[0052] Specifically, in the above-mentioned embodiment, the first mounting hole 1111 is a structure on the top wall 111 for connecting to the battery module 30. The first mounting hole 1111 can be a spatial structure directly formed when the top wall 111 is integrally formed, or a spatial structure formed by the top wall 111 after post-processing. In some embodiments, the first mounting hole 1111 can be a spatial structure formed by the inner side surface of the top wall 111 being recessed toward the outer side surface away from the accommodating cavity 15. In other embodiments, a boss is provided on the inner side surface of the top wall 111, and the first mounting hole 1111 is a spatial structure formed by the end surface of the boss facing the center of the accommodating cavity 15 being recessed toward the outer side surface of the top wall 111. At this time, the distance between the first mounting hole 1111 and the battery module 30 is smaller, making it easier to install.

[0053] A connecting post 313 is provided at the first end 3101 of the first bracket. The connecting post 313 is a structure for connecting to the first mounting hole 1111, wherein the connecting post 313 is provided with a second mounting hole 3131. The second mounting hole 3131 passes through the connecting post 313 so that the locking member can be inserted into the second mounting hole 3131 from one side of the connecting post 313 and at least partially extend into the first mounting hole 1111. The size and number of the second mounting holes 3131 correspond to the size and number of the first mounting holes 1111, respectively. In one example, the second mounting holes 3131 correspond one-to-one with the first mounting holes 1111. In addition, the second mounting hole 3131 and the first mounting hole 1111 need to be aligned to ensure that a smooth communication path can be formed between the two for the insertion of the locking member.

[0054] The second bracket 33 is provided with a through-hole 333. The through-hole 333 is a spatial structure of the second bracket 33 that provides space for the connection column 313 to pass through. Specifically, the size and number of the through-hole 333 correspond to the size of the outer peripheral wall of the connection column 313 and the number of the connection column 313, respectively. The locking member is a structure for locking the first bracket 31 with the top wall 111, and the locking member passes through the first mounting hole 1111 and the second mounting hole 3131 in sequence. In the process of connecting the first bracket 31 and the second bracket 33 to form the battery module 30 of the integral structure, the connection column 313 also passes through the corresponding through-hole 333, and the second mounting hole 3131 is aligned with the first mounting hole 1111, so that the locking member can pass through the second mounting hole 3131 and lock with the first mounting hole 1111. At this point, the connection between the battery module 30 and the top wall 111 is completed. Therefore, the energy storage power supply 100 of the present application locks the battery module 30 to the top wall 111 of the first shell 11 through a separately provided locking member, and there is no need to provide a connecting column on the top wall 111 through a laminating process. As a result, stress concentration will not occur, and there is no risk of cracking of the top wall 111, which can ensure the product quality and reliability of the energy storage power supply 100.

[0055] In the embodiments of the present application, to avoid the problem of a weak single-point locking connection when there is only one locking member, multiple locking members are provided. Since the first end 301 of the battery module is locked to the top wall 111 of the first shell 11 via the locking member, a unique hanging installation method is adopted in this application. The positional distribution of the locking members will directly affect the force distribution on the top wall 111, specifically the force distribution on the top wall 111 caused by the gravity of the battery module 30. Therefore, using the portion of the inner surface of the top wall 111 facing the battery module 30 as the reference plane, the locking members need to be evenly distributed within the reference plane. Specifically, in some embodiments, the locking members can be symmetrically arranged on two opposing sides of the reference plane. In other embodiments, the locking members can be arranged at the four corners of the reference plane. In still other embodiments, the locking members can be arranged at the four corners and the center of the reference plane. In still other embodiments, the reference plane can be divided into multiple, sequentially connected regions, with the locking members arranged at the center of each region. In summary, the first end 301 of the battery module is locked to the top wall 111 of the first shell 11 through reasonably distributed locking members, which evenly distributes the force on the top wall 111 and enhances the stability of the overall structure of the energy storage power supply 100.

[0056] Please refer to Figure 1 and Figure 4 In some embodiments, when the energy storage power supply 100 is in use, the top wall 111 is the top wall, and the peripheral side wall 113 is the side wall surrounding the top wall. The second shell 13 and the first shell 11 are separate structures.

[0057] Because current energy storage power supplies typically lock the battery module to the front housing, the front housing and left and right decorative covers are separated to meet installation and wiring harness connection requirements. This reduces the structural integrity and strength of the housing, which in turn affects the safety and service life of the energy storage power supply. Furthermore, the left-right split design increases the number of parts and complicates the assembly process, increasing the production cost and production cycle of the energy storage power supply.

[0058] To address the aforementioned issues, some embodiments of the energy storage power supply 100 of the present application utilize a split housing 10, namely, a second housing 13 and a first housing 11. Furthermore, when the energy storage power supply 100 is in use, the top wall 111 serves as the top wall, and the peripheral sidewalls 113 serve as sidewalls surrounding the top wall. The other end of the peripheral sidewall 113, distal from the top wall 111, defines an opening for the integral installation of the battery module 30 within the accommodating cavity 15. This opening is sealed after the second housing 13 and the first housing 11 are connected. In this manner, during assembly of the energy storage power supply 100, the battery module 30 can be first integrally mounted on the top wall (top wall 111), followed by the assembly of the second housing 13 and the first housing 11. This hoisting installation method significantly reduces the number of disassembled components of the housing 10 and significantly improves the bonding strength of the energy storage power supply 100. Furthermore, this hoisting installation method reduces assembly complexity, streamlines the assembly process, and enables efficient and precise automated assembly, thereby significantly improving the production efficiency of the energy storage power supply 100.

[0059] The support member 50 is an element used to connect the end face of the second end 302 of the battery module to the peripheral side wall 113 of the first shell 11. The size of the support member 50 needs to be adapted to the distance between the battery module 30 and the peripheral side wall 113. Specifically, the support member 50 can be a flat plate structure or a bent structure having a bent portion and a flat plate portion. In the case where the support member 50 is a flat plate structure, the structure of the support member 50 is simple and the cost is low. In the case where the support member 50 is a bent structure, the support member 50 can make way for other components in the accommodating cavity 15, making the internal layout of the energy storage power supply 100 and the installation of components more flexible. The support member 50 connects the peripheral side wall 113 of the first shell 11 and the end face of the second end 302 of the battery module, supporting the battery module 30. At this time, the supporting force of the support member 50 on the battery module 30 can support the battery module 30 against the top wall 111. Therefore, the battery module 30 not only has a bonding force with the top wall 111 at the first end 301 , but also has a bonding force with the peripheral side wall 113 at the second end 302 through the support member 50 , thereby enhancing the structural stability of the energy storage power supply 100 .

[0060] Please refer to Figure 4 In some embodiments, the material of the support member 50 includes titanium alloy.

[0061] The support member 50 not only connects the peripheral sidewall 113 and the battery module 30 but also supports the battery module 30. Therefore, the support member 50 is typically subjected to stress, and the magnitude of this stress may vary with the transportation and / or use of the energy storage power supply 100. Therefore, the strength of the support member 50 directly impacts the structural stability and safety of the energy storage power supply 100. A key factor in determining the strength of the support member 50 is its material.

[0062] Titanium alloys are alloys of titanium and other elements, including but not limited to aluminum, vanadium, and molybdenum. Titanium alloys possess a unique microcrystalline structure, and their properties vary depending on the doping elements. Compared to conventional sheet metal supports, titanium alloy supports offer numerous advantages.

[0063] On the one hand, the tensile strength of titanium alloy can reach 2-3 times that of conventional sheet metal materials. The inventors of this application have verified through finite element analysis and actual testing that, compared to supports made of conventional sheet metal materials of the same thickness, the support member 50 comprising titanium alloy in this application can increase torsional rigidity by 40% and bending strength by 35%. This allows the energy storage power supply 100 to effectively withstand external impacts under complex operating conditions, and the support member 50 comprising titanium alloy ensures stable operation of the energy storage power supply 100 (the technical solutions below compare support members 50 comprising titanium alloy with support members 50 made of conventional sheet metal materials of the same thickness). Furthermore, the support member 50 comprising titanium alloy has excellent damping properties, enabling the energy storage power supply 100 to withstand extreme environments up to a seismic intensity of 9, ensuring stable operation even in severe vibration scenarios such as earthquakes. In addition, the inventors of the present application conducted a 1m high free drop test on the energy storage power supply 100 and concluded that the battery module 30 is locked to the shell 10 by a locking member, and combined with the support member 50 made of high-strength titanium alloy material, the energy storage power supply 100 has strong impact resistance and can effectively protect the internal battery cell assembly 37 and other components to operate safely.

[0064] On the other hand, titanium alloy also has the advantage of low density, with a density of only about 60% of conventional sheet metal materials. That is, in comparison, the support member 50 comprising titanium alloy has a smaller mass. Therefore, the energy storage power supply 100 using the support member 50 comprising titanium alloy has a high overall strength while also having the advantage of being lightweight. It should also be noted that the elastic modulus of titanium alloy is closer to that of the material of the battery cell 371. Therefore, the use of the support member 50 comprising titanium alloy can effectively suppress the stress concentration problem in the battery cell 371 caused by the difference in material deformation, thereby improving the service life and safety of the battery cell 371.

[0065] Please refer to Figure 3 and Figure 5 In some embodiments, a supporting portion 1131 is provided on the inner side of the peripheral sidewall 113, and the second end 302 of the battery module includes a fixing portion 315. The support member 50 includes a first connecting portion 51 and a second connecting portion 53. The first connecting portion 51 is connected to the supporting portion 1131 via a first fixing member, and the second connecting portion 53 is connected to the fixing portion 315 via a second fixing member.

[0066] Since the support member 50 is a structure that connects the end surface of the second end 302 of the battery module and the peripheral side wall 113 of the first shell 11, and is at least partially a flat plate structure, the connection between the support member 50 and the peripheral side wall 113, and the connection between the support member 50 and the second end 302 of the battery module, both need to have a certain connection area to ensure a secure connection. The supporting portion 1131 is a structure used to support the support member 50 in a direction perpendicular to the support member 50. The supporting portion 1131 is arranged on the inner side of the peripheral side wall 113, and the supporting portion 1131 and the support member 50 are in surface contact. The fixing portion 315 is a structure that is substantially parallel to the flat plate structure of the support member 50 and is in contact with the support member 50. The fixing portion 315 is arranged at the second end 302 of the battery module, and the fixing portion 315 and the support member 50 are also in surface contact.

[0067] Specifically, in some embodiments, the support member 50 includes a first connecting portion 51 and a second connecting portion 53, wherein the first connecting portion 51 is in surface contact with the supporting portion 1131, and the second connecting portion 53 is in surface contact with the fixing portion 315. Moreover, a structure for a mating connection is provided between the first connecting portion 51 and the supporting portion 1131. In some embodiments, the first connecting portion 51 is provided with a through hole, and the supporting portion 1131 is provided with a connecting hole. In other embodiments, the first connecting portion 51 is provided with a boss, and the supporting portion 1131 is provided with a connecting hole. A structure for a mating connection is also provided between the second connecting portion 53 and the fixing portion 315. In some embodiments, the second connecting portion 53 is provided with a through hole, and the fixing portion 315 is provided with a connecting hole. In other embodiments, the second connecting portion 53 is provided with a boss, and the fixing portion 315 is provided with a connecting hole.

[0068] The first fixing member (not shown) is a structure for connecting the first connecting portion 51 and the supporting portion 1131. The selection of the first fixing member is determined by the matching method of the first connecting portion 51 and the supporting portion 1131. For example, if the first connecting portion 51 has a through hole and the supporting portion 1131 has a connecting hole, the first fixing member can be a screw. In this case, the first fixing member passes through the through hole and connects with the connecting hole to achieve the connection between the first connecting portion 51 and the supporting portion 1131. The second fixing member (not shown) is a structure for connecting the second connecting portion 53 and the fixing portion 315. The selection of the second fixing member is determined by the matching method of the second connecting portion 53 and the fixing portion 315. For example, if the second connecting portion 53 has a through hole and the fixing portion 315 has a connecting hole, the second fixing member can be a screw. In this case, the second fixing member passes through the through hole and connects with the connecting hole to achieve the connection between the second connecting portion 53 and the fixing portion 315.

[0069] The arrangement of the supporting portion 1131 and the fixing portion 315 allows the support member 50 to better connect the battery module 30 and the peripheral sidewall 113. This further stabilizes the internal structure of the energy storage power supply 100, further increasing its strength and service life. Furthermore, the arrangement of the supporting portion 1131 and the fixing portion 315 creates a physical barrier between the battery module 30 and the peripheral sidewall 113, preventing components such as screws from falling into the depths of the accommodating cavity 15.

[0070] Please refer to Figures 3 to 5 In some embodiments, the battery module 30 includes a plurality of battery cells 371 , each of which includes a first electrode and a second electrode with opposite polarities. In the direction from the top wall 111 to the accommodating cavity 15 , the support member 50 is located between the first electrode and the second electrode.

[0071] Each cell 371 in the battery module 30 has a first pole and a second pole with opposite polarities in the arrangement direction, so the first poles of all cells 371 correspond to the first end 301 of the battery module, and the second poles of all cells 371 correspond to the second end 302 of the battery module. At the same time, after all cells 371 are electrically connected to each other and form a specific current flow path, the battery module 30 has a total positive pole and a negative pole, such as Figure 5 B- and B+ in. The support member 50 can divide the accommodating cavity 15 into two spatial areas in the direction from the top wall 111 to the second shell 13. The first pole and the second pole are respectively located at the two ends of the battery module 30, that is, respectively located in the two spatial areas of the accommodating cavity 15. Therefore, the support member 50 plays a role in effectively separating the positive and negative pole areas. At this time, if a screw falls or conductive debris enters, the support member 50 and the supporting portion 1131 can both play a role in preventing the screws and conductive debris from falling, thereby avoiding electrical short circuits of the first pole and / or the second pole caused by the falling of screws and conductive debris, thereby improving the safety and stability of the energy storage power supply 100 during assembly, transportation and use.

[0072] Please refer to Figures 3 to 5 In some embodiments, the energy storage power supply 100 further includes an inverter, which is disposed in the accommodating cavity 15 and between the second end 302 of the battery module and the second shell 13 .

[0073] To enable the energy storage power supply 100 to convert AC and DC power, it also includes an inverter (not shown). An inverter is a device used to convert AC and DC power. When charging the energy storage power supply 100, the inverter converts the AC power used for charging into DC power and stores it in the battery module 30. When discharging the energy storage power supply 100, the inverter converts the DC power output by the battery module 30 into AC power for use by electrical devices. The inverter is housed within the accommodating cavity 15 and is located in the space between the second end 302 of the battery module and the second shell 13. This results in a compact layout and a rational structure within the energy storage power supply 100. The inverter also allows the energy storage power supply 100 to better adapt to charging devices and electrical devices.

[0074] Second, please refer to Figure 1 、 Figure 2 and Figure 4 , the present application provides an assembly method of an energy storage power supply, comprising: 01: Provide a battery module 30, the battery module 30 including a first end 301 and a second end 302 opposite to each other; 03: Fasten the first end 301 of the battery module to the top wall 111 of the first shell 11 through a fastening member; and, 05: Combine the second shell 13 with the peripheral side wall 113 of the first shell 11 to close the accommodating cavity 15.

[0075] In the above embodiment, the battery module 30, the first end 301 of the battery module, the second end 302 of the battery module, the locking member, the first shell 11, the top wall 111, the second shell 13, the peripheral side wall 113 and the accommodating cavity 15 all adopt the above definitions and are not repeated here.

[0076] Specifically, at least one battery cell 371 is first mounted on the first bracket 31. Then, the second bracket 33 is connected to the first end 3101 of the first bracket, and the at least one battery cell 371 is clamped in the mounting groove 35 formed by the first bracket 31 and the second bracket 33 to form the battery module 30.

[0077] Next, align the battery module 30 with the mounting position, and then insert the locking member through the second mounting hole 3131 and into the first mounting hole 1111 to lock the first end 301 of the battery module to the top wall 111 of the first shell 11 .

[0078] Finally, the second shell 13 is aligned with the opening of the side wall 113 of the first shell 11 away from the top wall 111. The second shell 13 is then connected to the side wall 113 of the first shell 11 by welding, snapping, gluing, or a combination of these methods to seal the housing 10 and enclose the accommodating cavity 15. The energy storage power supply 100 is now assembled.

[0079] Please refer to Figure 2 and Figure 4 In some embodiments, 01: providing a battery module 30, comprising: 011: Install at least one battery cell 371 on the first bracket 31; and, 013: Connect the second bracket 33 to the first end 3101 of the first bracket, and clamp at least one battery cell 371 in the installation groove 35 surrounded by the first bracket 31 and the second bracket 33 to form a battery module 30.

[0080] In the above embodiment, the battery cell 371 , the first bracket 31 , the second bracket 33 , the first end 3101 of the first bracket and the mounting groove 35 are all defined as above and are not described again here.

[0081] Specifically, the battery cell 371 is first installed in the first insertion hole of the first bracket 31 to ensure precise installation of the battery cell 371 in the first bracket 31. Then, the first coupling member 311 is engaged with the second coupling member 331, and the second bracket 33 is aligned with the first bracket 31. The battery cell 371 is then aligned with the second insertion hole. As a result, at least one battery cell 371 is installed in the installation slot 35, sandwiched between the first bracket 31 and the second bracket 33, completing the installation of the battery module 30.

[0082] Please refer to Figure 4 and Figure 5 In some embodiments, before step 05: combining the second shell 13 with the peripheral side wall 113 of the first shell 11, the assembly method further includes: 04: Use the support member 50 to connect the second end 302 of the battery module to the peripheral side wall 113 of the first shell 11. The material of the support member 50 includes titanium alloy.

[0083] The support member 50 is defined as above and will not be further described here. In the above embodiment, the first connecting portion 51 is first aligned with the supporting portion 1131, and the second connecting portion 53 is aligned with the fixing portion 315.
