Description

Technical Field

[0002] With the advancement of technology, energy storage technology is booming, and the structure of energy storage power supplies needs further optimization to meet increasingly stringent market requirements. Currently, in energy storage power supplies, battery modules are usually attached to the front shell on their sides. This causes the center of gravity of the battery module to deviate significantly from the center of the energy storage power supply. This structure can easily lead to vibration coupling effects during operation, reducing the stability of the energy storage power supply, thereby increasing the risk of mechanical fatigue and shortening its service life.

The first connecting member and the second connecting member are inserted into each other to connect the second bracket to the first bracket. A mounting groove is formed between the first bracket and the second bracket. The cell assembly includes a plurality of cells, one end of which is inserted into the first insertion hole and the other end of which is inserted into the second insertion hole.

[0006] In some embodiments, the battery module further includes a first electrical connection assembly and a second electrical connection assembly. The first electrical connection assembly is disposed on the side of the first bracket opposite to the first insertion hole and includes a plurality of first electrical connectors, which are welded to a first electrode of the battery cell. The second electrical connection assembly is disposed on the side of the second bracket opposite to the second insertion hole and includes a plurality of second electrical connectors, which are welded to a second electrode of the battery cell. The polarity of the second electrode is opposite to that of the first electrode.

[0007] In some embodiments, the first bracket is provided with an isolator that surrounds the first electrical connector.

[0008] In some embodiments, the inner side of the top wall within the accommodating cavity has a first mounting hole. The first bracket includes a first end and a second end opposite to each other. The second bracket has a through hole. The first end of the first bracket has a connecting post, the connecting post having a second mounting hole and passing through the through hole. The locking member passes through the second mounting hole and locks itself with the first mounting hole.

[0009] In some embodiments, the support member is made of titanium alloy.

[0010] In some embodiments, the battery module includes multiple cells, each cell including a first electrode and a second electrode with opposite polarities. The support member is located between the first electrode and the second electrode in the direction from the top wall to the accommodating cavity.

[0011] In some embodiments, a support portion is provided on the inner side of the peripheral sidewall, and the second end of the battery module includes a fixing portion.

[0014] In the energy storage power supply of this application, the battery module is locked to the top wall of the first housing by locking components, so that the battery module is housed in the receiving cavity. Simultaneously, the energy storage power supply also supports the battery module by support components, holding it against the top wall, further reinforcing the installation of the battery module. Compared to energy storage power supplies where the battery module is side-mounted and locked to the front housing, the center of gravity of the battery module in this application's energy storage power supply can be closer to the center of the energy storage power supply. This prevents vibration coupling effects during operation, improving the stability of the energy storage power supply and reducing the risk of mechanical fatigue. Furthermore, the energy storage power supply has greater structural strength, thus extending its service life.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

[0023] With the advancement of technology, energy storage technology is booming, and the structure of energy storage power supplies needs further optimization to meet increasingly stringent market requirements. Currently, in energy storage power supplies, battery modules are typically mounted on the front shell in a side-mounted manner. This causes the center of gravity of the battery module to deviate significantly from the center of the energy storage power supply. This structure easily leads to vibration coupling effects during operation, reducing the stability of the energy storage power supply, thereby increasing the risk of mechanical fatigue and shortening its service life. To address this problem, this application provides an energy storage power supply (… Figure 1 (as shown) and the assembly method of the energy storage power supply.

[0024] Please see Figures 1 to 4 The energy storage power supply 100 provided in this 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 receiving cavity 15. The first shell 11 includes a top wall 111 and a peripheral side wall 113, with the peripheral side wall 113 extending from the periphery of the top wall 111. The battery module 30 is housed within the receiving cavity 15. The battery module 30 includes a first end 301 and a second end 302 facing 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 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, multi-functional portable energy storage device, applicable to both off-grid microgrid systems and grid-connected systems. When applied to an off-grid microgrid system, the energy storage power supply 100 can replace traditional fuel generators, providing clean energy to the loads in the off-grid microgrid system. When applied to a grid-connected system, in addition to providing power to the loads in the grid, the energy storage power supply 100 can also provide power to the grid during periods of high electricity prices, and when there is still a surplus after supplying power to the loads. Of course, the energy storage power supply 100 can also be applied to outdoor camping, emergency disaster relief, and professional operations (such as photography and engineering) to solve the electricity needs of areas without grid access or with unstable power.

[0026] The housing 10 is a structure used to protect, house, and / or install functional components such as the battery module 30 in the energy storage power supply 100. The material of the housing 10 can be, but is not limited to, metal and plastic. When the housing 10 is made of metal, it has high structural strength, is not easily damaged, and has a long service life. When the housing 10 is made of plastic, it is lightweight, easy to carry, and has a lower cost. In some embodiments, the housing 10 is a split structure to facilitate the installation of functional components such as the battery module 30 inside the housing 10. Specifically, the housing 10 includes a first shell 11 and a second shell 13, which are split structures. The first shell 11 and the second shell 13 can be made of the same material or different materials. The first shell 11 and the second shell 13 are connected to each other after being formed separately. The connection method between the first shell 11 and the second shell 13 can be a detachable connection or a non-detachable connection. Detachable connections include, but are not limited to, one or more combinations of methods such as screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of methods such as gluing, welding, and sintering. The terms "detachable connection" and / or "non-detachable connection" used below will be defined as above and will not be repeated. The first shell 11 and the second shell 13 are interconnected to form a receiving cavity 15. The receiving cavity 15 is a spatial structure for accommodating and installing functional components such as the battery module 30. The functional components such as the battery module 30 are housed in the receiving cavity 15 through connection with the first shell 11 and / or the second shell 13, and are fixed in position relative to the receiving cavity 15 to stabilize the structure of the energy storage power supply 100.

[0027] The first shell 11 is the portion of the shell 10 used for connection with the battery module 30. The top wall 111 is the side wall of the first shell 11 away from the second shell 13. The peripheral side wall 113 is a side wall extending from the periphery of the top wall 111. The top wall 111 and the peripheral side wall 113 can be integrally formed or separately formed. When the top wall 111 and the peripheral side wall 113 are integrally formed, the first shell 11 has higher strength. When 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. In this case, the molds for manufacturing the top wall 111 and the peripheral side wall 113 are smaller, and the overall processing of the first shell 11 is simpler.

[0028] The second shell 13 is a part of the shell 10 used to connect with the first shell 11 to make the shell 10 a monolithic structure with a certain strength. The peripheral 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 is adapted to the size of the opening. Therefore, the second shell 13 can be installed at the opening of the peripheral sidewall 113 of the first shell 11. At this time, one or more of the following methods, such as welding, snap-fitting, and gluing, can be used to connect the second shell 13 to the peripheral sidewall 113 of the first shell 11, thereby sealing the accommodating cavity 15.

[0029] Battery module 30 is the core module of energy storage power supply 100, used for storing and releasing electrical energy. Depending on the different application scenarios, energy storage power supply 100 has different capacities, meaning battery module 30 has different capacities. For example, in small household or commercial energy storage power supplies 100, the capacity of battery module 30 is typically from several kilowatt-hours to tens of kilowatt-hours. Battery module 30 is housed within housing 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 housing 11, and the second end 302 corresponds to the second housing 13. The first end 301 of the battery module is connected to the first housing 11 through its connection with the top wall 111. 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. At this time, the position of the battery module 30 within the receiving cavity 15 can be adjusted by adjusting the position of the first end 301 of the battery module and the position of the top wall 111 in conjunction with the locking member; that is, the position of the center of gravity of the battery module 30 relative to the receiving cavity 15 can be adjusted. The optimal position of the center of gravity of the battery module 30 is the center of the energy storage power supply 100, at which point the overall center of gravity of the energy storage power supply 100 is most stable.

[0031] In some embodiments, the locking element is a screw, in which case the top wall 111 needs to have a threaded structure that mates with the locking element. In other embodiments, the locking element is a snap-fit ​​structure (not a screw) that has a certain nesting relationship 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-fit ​​connection, or by snap-fit ​​connection combined with welding or gluing. The second end 302 of the battery module is opposite to the second shell 13, and there is no connecting structure 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 install other components or reserved as a heat dissipation area for the battery module 30.

[0032] In the energy storage power supply 100 of this application, the battery module 30 is locked to the top wall 111 of the first housing 11 by a locking member, so that the battery module 30 is housed in the receiving cavity 15. Simultaneously, the energy storage power supply 100 also supports the battery module 30 by a support member 50, so that the battery module 30 abuts against the top wall 111, further reinforcing the installation of the battery module 30. Compared to energy storage power supplies where the battery module is side-mounted and locked to the front housing, the center of gravity of the battery module 30 in the energy storage power supply 100 of this application can be close to the center of the energy storage power supply 100. This prevents vibration coupling effects during operation, improving the stability of the energy storage power supply 100, thereby reducing the risk of mechanical fatigue. Furthermore, the energy storage power supply 100 has greater structural strength, thus extending its service life.

[0033] When the battery module 30 is mounted on the top wall 111 using a locking device, if it is not connected to the peripheral side wall 113, the battery module 30 may shake during the transportation of the energy storage power supply 100. This shaking will weaken the connection between the first end 301 of the battery module and the top wall 111. With prolonged use, the battery module 30 may detach from the housing 10, potentially causing an explosion or fire, resulting in insufficient safety of the energy storage power supply 100. Therefore, the energy storage power supply 100 of this application further strengthens the connection between the battery module 30 and the first housing 11 by providing at least one support member 50. The support member 50 can be disposed on any one or more sides of the peripheral side wall 113 and between any one or more sides of the corresponding battery module 30. The more support members 50 there are, the more securely the battery module 30 is bonded to the first housing 11.

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

[0035] The dimensions of the support member 50 need to be adapted to the distance between the battery module 30 and the peripheral sidewall 113. Specifically, the support member 50 can be a flat structure or a bent structure with both a bent portion and a flat portion. When the support member 50 is a flat structure, its structure is simple and its cost is low. When the support member 50 is a bent structure, it can make way for other components within 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 sidewall 113 of the first shell 11 and the end face of the second end 302 of the battery module, providing support for the battery module 30. At this time, the supporting force of the support member 50 on the battery module 30 is sufficient to support the battery module 30 against the top wall 111. Therefore, the battery module 30 not only has a bonding force between its first end 301 and the top wall 111, but also a bonding force between its second end 302 and the peripheral sidewall 113 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 cell assembly 37. The first bracket 31 is provided with a first connector 311 and a plurality of first insertion holes. The second bracket 33 is provided with a second connector 331 and a plurality of second insertion holes. The first connector 311 and the second connector 331 are inserted into each other so that the second bracket 33 is connected to the first bracket 31. A mounting groove 35 is formed between the first bracket 31 and the second bracket 33. The cell assembly 37 includes a plurality of cells 371, which are disposed in the mounting groove 35. One end of each cell 371 is inserted into a first insertion hole, and the other end is inserted into a second insertion hole.

[0037] Specifically, the cell assembly 37 is the core component of the battery module 30 used for storing and releasing electrical energy. Specifically, the cell assembly 37 includes at least one cell 371. The cell 371 is the smallest unit for storing and releasing electrical energy. The battery module 30 can achieve 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 with opposite polarities. 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, parallel, or in a mixed configuration (in this application, "multiple" refers to one or more, and "multiple" can be, but is not limited to, two, three, or four, etc.). A mixed configuration means that multiple cells 371 are connected in both series and parallel. Multiple battery cells 371 can be directly connected in series, parallel, or mixed to form a battery cell assembly 37 for charging and discharging the energy storage power supply 100. Therefore, the safety of the battery cell assembly 37 directly affects the safety and lifespan of the energy storage power supply 100. Understandably, 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 manufactured, it may be transported and / or used. During transport, the battery cell assembly 37 in the battery module 30 may be subjected to compressive forces as the energy storage power supply 100 moves. 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. This charging and / or discharging generates heat, causing the internal temperature of the energy storage power supply 100 to rise. When the energy storage power supply 100 stops working, its internal temperature will drop back to near room temperature. These fluctuations in internal temperature cause thermal expansion and contraction, which in turn causes the battery cell assembly 37 to be subjected to compressive forces. Any of these compressive forces could pose a risk of explosion to the battery cell 371.

[0039] The battery module 30 of the energy storage power supply 100 of this application installs and protects the cell assembly 37 through a first bracket 31 and a second bracket 33. The first bracket 31 is a structure used to support the cell assembly 37 and limit its position. 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 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 base plate disposed at the second end 3102 of the first bracket and a limiting part extending from the base plate to the first end 3101 of the first bracket, the limiting part and the base plate forming 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 the first insertion hole. All the battery cells 371 are accommodated in the limiting space and are limited 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, together with the first bracket 31, further limits the positioning of the battery cell assembly 37. The second bracket 33 is generally flat and has multiple second insertion holes. The size and number of the second insertion holes correspond to the size and number of the battery cells 371, so that at least a portion of any battery cell 371 can be accommodated within one of the second insertion holes. Specifically, the second bracket 33 can close onto the first bracket 31 at its first end 3101, allowing the second bracket 33 to cooperate with the first bracket 31 to form a mounting groove 35. At this time, the space between the first bracket 31 and the second bracket 33 is the mounting groove 35, which includes at least a portion of the first insertion hole and at least a portion of the second insertion hole. The battery cell assembly 37 is disposed within the mounting groove 35, i.e., the battery cell assembly 37 is sandwiched 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 insertion hole, the second bracket 33 covers the first bracket 31 and limits the other end of the battery cell 371 in the battery cell assembly 37 by the second insertion hole, thereby realizing the connection of the first bracket 31, the battery cell assembly 37 and the second bracket 33 into 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 materials of the first bracket 31 and / or the second bracket 33 can be, but are not limited to, metal and plastic. When the first bracket 31 and / or the second bracket 33 are made of metal, they 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 having a lower cost. In addition, at least a portion of the materials of the first bracket 31 and the second bracket 33 are insulating materials to ensure the safety of the battery module 30.

[0042] To simplify the installation process of the battery module 30 while ensuring its stability, the first bracket 31 is provided with a first coupling 311, and the second bracket 33 is provided with a second coupling 331. The insertion of the first coupling 311 and the second coupling 331 achieves the relative connection between the first bracket 31 and the second bracket 33. In some embodiments, the first coupling 311 is a locking hole, and the second coupling 331 is a deformable hook. The hook has two states: an initial state and a deformed state. The hook passes through the locking hole in the deformed state. After the hook returns to its initial state, the hook-shaped structure of the hook abuts against the periphery of the locking hole to achieve engagement between the locking hole and the hook, thereby connecting the first bracket 31 and the second bracket 33. In other embodiments, the first coupling 311 is a deformable hook, and the second coupling 331 is a locking hole, such as... Figure 2 As shown, the hook passes through the engagement hole in a deformed state. After the hook returns to its initial state, the hook-shaped structure of the hook abuts against the periphery of the engagement hole to achieve engagement, thereby connecting the first bracket 31 and the second bracket 33. Regardless of the implementation method described above, the first bracket 31 and the second bracket 33 are connected by a precision engagement to achieve rapid, accurate positioning and tight connection. Furthermore, the precision engagement connection replaces the traditional threaded connection, reducing screw procurement costs and assembly steps. Calculations show that, compared to the threaded connection, the engagement connection method of this application reduces the assembly time of a single energy storage power supply 100 by more than 30% and lowers the production cost of the energy storage power supply 100 by 25%, effectively enhancing the market competitiveness of the energy storage power supply 100 of this application.

[0043] In the energy storage power supply 100 of this application, the cell assembly 37 is disposed in the mounting groove 35 formed by the first bracket 31 and the second bracket 33, and the first connecting member 311 and the second connecting member 331 are inserted into each other, so that the first bracket 31, the cell assembly 37 and the second bracket 33 can be connected into a battery module 30 with an integral structure. The battery module 30 with the integral structure is locked to the first shell 11 by locking members. This assembly method can effectively disperse the compressive force on the cell assembly 37 during the transportation and / or use of the energy storage power supply 100, thereby reducing the risk of explosion of the cell assembly 37 and improving the usability and installability 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 assembly 38 and a second electrical connection assembly 39. The first electrical connection assembly 38 is disposed on the side of the first bracket 31 opposite to the first insertion hole and includes a plurality of first electrical connectors 381, which are welded to the first electrode of the battery cell 371. The second electrical connection assembly 39 is disposed on the side of the second bracket 33 opposite to the second insertion hole and includes a plurality of second electrical connectors 391, which are welded to the second electrode of the battery cell 371. The polarity of the second electrode is opposite to that of the first electrode. The first bracket 31 is provided with an isolator 317 surrounding the first electrical connectors 381.

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

[0046] The number of second electrical connectors 391 corresponds to the number of battery cells 371. Both the first electrical connector 381 and / or the second electrical connector 391 are made of conductive materials. Specifically, the first electrical connector 381 and / or the second electrical connector 391 can be aluminum busbars. In this case, the current collection effect of the first electrical connector 381 and / or the second electrical connector 391 is better, and the cost is lower. After the battery cell assembly 37 is installed into the mounting slot 35 and precisely positioned relative to the first bracket 31 and the second bracket 33, the first electrical connector 38 is welded to the first electrode of the battery cell 371, and the second electrical connector 39 is welded to the second electrode of the battery cell 371, thereby realizing the series, parallel, or mixed connection of multiple battery cells 371. Therefore, the energy storage power supply 100 of this application, by setting the first electrical connector 38 and the second electrical connector 39, can realize the collection and distribution of current among the various battery cells 371, ensuring the efficient and safe operation of the battery module 30.

[0047] Please refer to further information. Figure 3 The isolator 317 is a structure used to prevent electrical short circuits caused by incorrect electrode connections between multiple battery cells 371. Specifically, the isolator 317 is a protruding structure formed by the end face of the second end 3102 of the first bracket protruding towards the second shell 13. The isolator 317 and the first bracket 31 can be separately formed or integrally formed. When the isolator 317 and the first bracket 31 are separately formed, the isolator 317 and the first bracket 31 can be detachably connected or non-detachably connected. The material of the isolator 317 can be the same as or different from the material of the first bracket 31, and the material of the isolator 317 is also an insulating material.

[0048] At least two isolators 317 are grouped together and disposed around the periphery of the first electrical connector 381 to shield at least a portion of the outer edge of the first electrical connector 381. In this case, the isolators 317 can restrict contact between external substances and the first electrical connector 381, thus serving an isolation function. Simultaneously, the isolators 317 also limit the position of the first electrical connector 381, simplifying its installation and positioning. Therefore, in the event of a screw falling off or conductive debris entering, the isolators 317 can effectively prevent screws and conductive debris from approaching the first electrical connector 381 and the electrodes, thereby effectively preventing electrical short circuits and further improving the reliability of the energy storage power supply 100.

[0049] 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 an isolator 317, resulting in the strongest isolation effect. 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 periphery of the first electrical connectors 381 near the periphery of the first support 31, while isolators 317 may not be provided around the periphery of the first electrical connectors 381 near the center of the first support 31. This ensures isolation while saving costs.

[0050] Please refer to Figure 6 and Figure 7 In some embodiments, the inner side 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. The second bracket 33 is provided with a through hole 333. The first end 3101 of the first bracket is provided with a connecting post 313, which is provided with a second mounting hole 3131 and passes through the through hole 333. A locking member passes through the second mounting hole 3131 and locks with the first mounting hole 1111.

[0051] Current energy storage power supplies have a connecting structure formed by a molding process on the front shell. This connecting structure is inserted into the connecting holes on the battery module to fix the battery module and the front shell. However, during the injection molding process of the connecting structure into the front shell, the complex effects of the shrinkage stress of the injection molding material and the injection pressure can easily cause stress concentration at the connecting structure, resulting in a high risk of cracking in the connecting structure and / or the front shell, affecting the product quality and reliability of the energy storage power supply. To solve this problem, the energy storage power supply 100 of this application introduces a locking component as a separate element in the connection process between the battery module 30 and the shell 10, thereby eliminating the molding process step in the manufacturing process of the energy storage power supply 100.

[0052] Specifically, in the above embodiments, the first mounting hole 1111 is a structure on the top wall 111 used for connecting to the battery module 30. The first mounting hole 1111 can be a spatial structure directly formed during the integral molding of the top wall 111, or a spatial structure formed by subsequent processing of the top wall 111. In some embodiments, the first mounting hole 1111 can be a spatial structure formed by the inner side of the top wall 111 recessed away from the outer side of the receiving cavity 15. In other embodiments, the inner side of the top wall 111 is provided with a protrusion, and the first mounting hole 1111 is a spatial structure formed by the end of the protrusion facing the center of the receiving cavity 15 recessed towards the outer side of the top wall 111. In this case, the distance between the first mounting hole 1111 and the battery module 30 is smaller, making installation easier.

[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 with the first mounting hole 1111, wherein the connecting post 313 is provided with a second mounting hole 3131. The second mounting hole 3131 extends 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 holes 3131 and the first mounting holes 1111 need to be aligned to ensure that a smooth communication path can be formed between them for the insertion of the locking member.

[0054] The second bracket 33 has a through hole 333. The through hole 333 is a spatial structure in the second bracket 33 that provides space for the connecting post 313 to pass through. Specifically, the size and number of through holes 333 correspond to the size of the outer peripheral wall of the connecting post 313 and the number of connecting posts 313, respectively. The locking member is a structure used to lock the first bracket 31 to the top wall 111. The locking member passes through the first mounting hole 1111 and the second mounting hole 3131 in sequence. During the process of connecting the first bracket 31 and the second bracket 33 to form the battery module 30 as an integral structure, the connecting post 313 also passes through the corresponding through hole 333. 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 time, the connection between the battery module 30 and the top wall 111 is completed. Therefore, the energy storage power supply 100 of this application locks the battery module 30 to the top wall 111 of the first shell 11 by a separately set locking member, without the need to set the connecting column on the top wall 111 by the molding process. As a result, stress concentration will not occur, the top wall 111 will not crack, and the product quality and reliability of the energy storage power supply 100 can be guaranteed.

[0055] In the embodiments of this application, to avoid the problem of weak single-point locking connection when there is only one locking member, the number of locking members is set to multiple. Since the first end 301 of the battery module is locked to the top wall 111 of the first shell 11 by the locking members, the hoisting installation method unique to this application is adopted. At this time, the positional distribution of the locking members will directly affect the force distribution of the top wall 111, that is, the force distribution of the top wall 111 caused by the gravity of the battery module 30. Therefore, taking the part of the inner side of the top wall 111 facing the battery module 30 as the reference plane, the locking members need to be evenly distributed in the reference plane. Specifically, in some embodiments, the locking members can be symmetrically arranged on two opposite 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 yet another embodiment, the reference plane can be equally divided into multiple sequentially connected areas, and the locking members are respectively arranged at the center of each area. In summary, the first end 301 of the battery module is locked to the top wall 111 of the first shell 11 by a reasonably distributed locking device, which evenly distributes the force on the top wall 111 and enhances the overall structural stability 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 a top wall, and the peripheral side wall 113 is a 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 have the battery module locked to the front casing, the front casing is often separated from the left and right decorative covers to meet installation and wiring harness connection requirements. This results in insufficient structural integrity and reduced structural strength, consequently affecting the safety and lifespan of the energy storage power supply. Furthermore, the split design increases the number of components and complicates the assembly process, raising the production cost and timeframe of the energy storage power supply.

[0058] To address the aforementioned issues, some embodiments of the energy storage power supply 100 in this application employ a split structure for the housing 10, specifically, the second housing 13 and the first housing 11 are separate structures. Furthermore, when in use, the energy storage power supply 100 has a top wall 111 and peripheral side walls 113 surrounding the top wall. The end of the peripheral side wall 113 away from the top wall 111 forms an opening for the battery module 30 to be integrally installed into the receiving cavity 15. This opening can be closed after the second housing 13 is connected to the first housing 11. In this case, during assembly of the energy storage power supply 100, the battery module 30 can be initially installed on the top wall (top wall 111), and then the second housing 13 and the first housing 11 can be assembled together. On one hand, this hoisting installation method significantly reduces the number of disassembled parts of the housing 10, significantly improving the bonding strength of the energy storage power supply 100; on the other hand, this hoisting installation method reduces assembly complexity, simplifies the assembly process, and achieves efficient and precise automated assembly, thereby greatly improving the production efficiency of the energy storage power supply 100.

[0059] The support member 50 is a component used to connect the end face of the second end 302 of the battery module to the peripheral sidewall 113 of the first shell 11. The dimensions of the support member 50 need to be adapted to the distance between the battery module 30 and the peripheral sidewall 113. Specifically, the support member 50 can be a flat structure or a bent structure with both a bent portion and a flat portion. When the support member 50 is a flat structure, its structure is simple and its cost is low. When the support member 50 is a bent structure, it can make way for other components within 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 sidewall 113 of the first shell 11 and the end face of the second end 302 of the battery module, providing support for the battery module 30. At this time, the supporting force of the support member 50 on the battery module 30 is sufficient to 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, which enhances the structural stability of the energy storage power supply 100.

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

[0061] The support member 50 serves two purposes: connecting the peripheral sidewall 113 and the battery module 30, and supporting the battery module 30. Therefore, the support member 50 is typically under stress, and the magnitude of this stress may vary depending on the transportation and / or use of the energy storage power supply 100. Consequently, the strength of the support member 50 directly affects the structural stability and safety of the energy storage power supply 100. One crucial factor determining the strength of the support member 50 is its material.

[0062] Titanium alloys are alloy materials formed by 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 support components made from conventional sheet metal, titanium alloy support components 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. Through finite element analysis and actual testing, the inventors of this application have verified that, compared to support components made of conventional sheet metal of the same thickness, the torsional stiffness of the support component 50 containing titanium alloy in this application can be increased by 40%, and the bending strength can be increased by 35%. At this point, the energy storage power supply 100 can effectively resist external impacts under complex working conditions, and the support component 50 containing titanium alloy ensures the stable operation of the energy storage power supply 100 (the technical solutions compared below refer to support components 50 containing titanium alloy and support components 50 made of conventional sheet metal of the same thickness). In addition, the support component 50 containing titanium alloy has excellent damping performance, enabling the energy storage power supply 100 to withstand extreme environmental tests with seismic intensity up to level 9, ensuring stable operation of the energy storage power supply 100 even in severe vibration scenarios such as earthquakes. In addition, the inventors of this application conducted a 1m drop test on the energy storage power supply 100 and concluded that the battery module 30 is locked to the housing 10 by the 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 ensure safe operation.

[0064] On the other hand, titanium alloy also has the advantage of low density, with a density only about 60% of that of conventional sheet metal materials. This means that, comparatively, the support component 50 containing titanium alloy is lighter. Therefore, the energy storage power supply 100 using the support component 50 containing titanium alloy has both high overall strength and the advantage of being lightweight. It should also be noted that the elastic modulus of titanium alloy is closer to that of the battery cell 371 material. Therefore, using the support component 50 containing titanium alloy can effectively suppress the stress concentration problem in the battery cell 371 caused by material deformation differences, improving the service life and safety of the battery cell 371.

[0065] Please refer to Figure 3 and Figure 5 In some embodiments, a support 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 support portion 1131 through a first fixing member, and the second connecting portion 53 is connected to the fixing portion 315 through a second fixing member.

[0066] Since the support member 50 is a structure connecting the end face of the second end 302 of the battery module to the peripheral sidewall 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 sidewall 113, and the connection between the support member 50 and the second end 302 of the battery module, both require 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 it. The supporting portion 1131 is located on the inner side of the peripheral sidewall 113, and it is in surface contact with the support member 50. The fixing portion 315 is a structure that is substantially parallel to the flat plate structure of the support member 50 and in contact with it. The fixing portion 315 is located at the second end 302 of the battery module, and it is also in surface contact with the support member 50.

[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. Furthermore, a structure for mating connection is provided between the first connecting portion 51 and the supporting portion 1131. In some embodiments, the first connecting portion 51 has a through hole, and the supporting portion 1131 has a connecting hole. In other embodiments, the first connecting portion 51 has a boss, and the supporting portion 1131 has a connecting hole. Similarly, a structure for mating connection is provided between the second connecting portion 53 and the fixing portion 315. In some embodiments, the second connecting portion 53 has a through hole, and the fixing portion 315 has a connecting hole. In other embodiments, the second connecting portion 53 has a boss, and the fixing portion 315 has a connecting hole.

[0068] The first fastener (not shown) is a structure used to connect the first connecting part 51 and the supporting part 1131. The selection of the first fastener depends on the mating method of the first connecting part 51 and the supporting part 1131. For example, if the first connecting part 51 has a through hole and the supporting part 1131 has a connecting hole, the first fastener can be a screw. In this case, the first fastener passes through the through hole and connects with the connecting hole to achieve the connection between the first connecting part 51 and the supporting part 1131. The second fastener (not shown) is a structure used to connect the second connecting part 53 and the fixing part 315. The selection of the second fastener depends on the mating method of the second connecting part 53 and the fixing part 315. For example, if the second connecting part 53 has a through hole and the fixing part 315 has a connecting hole, the second fastener can be a screw. In this case, the second fastener passes through the through hole and connects with the connecting hole to achieve the connection between the second connecting part 53 and the fixing part 315.

[0069] The arrangement of the support 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 makes the internal structure of the energy storage power supply 100 more stable, further increasing its strength and service life. Simultaneously, the arrangement of the support portion 1131 and the fixing portion 315 effectively creates a physical protective barrier in the space between the battery module 30 and the peripheral sidewall 113, preventing components such as screws from falling into the depths of the receiving 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 battery cell 371 including a first electrode and a second electrode with opposite polarities. A support member 50 is located between the first electrode and the second electrode in the direction from the top wall 111 to the accommodating cavity 15.

[0071] In the battery module 30, each cell 371 has a first and second pole with opposite polarities in its orientation. Therefore, 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. Furthermore, 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 and negative pole, such as... Figure 5 The B- and B+ electrodes are located in the first and second housings, respectively. The support member 50 divides the accommodating cavity 15 into two spatial regions along the direction from the top wall 111 to the second shell 13. The first and second electrodes are located at opposite ends of the battery module 30, i.e., in the two spatial regions of the accommodating cavity 15. Therefore, the support member 50 effectively separates the positive and negative electrode regions. In the event of a screw falling off or conductive debris entering, the support member 50 and the supporting portion 1131 can prevent the screw and conductive debris from falling, thereby avoiding electrical short circuits in the first and / or second electrodes caused by the falling screw and conductive debris. This improves 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 housing 13.

[0073] To enable the energy storage power supply 100 to convert AC to DC power, it also includes an inverter (not shown). The inverter is a device used to convert AC to 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 from the battery module 30 into AC power for use by electrical devices. The inverter is housed within the housing 15 and positioned in the space between the second end 302 of the battery module and the second housing 13. This results in a compact and rational layout within the energy storage power supply 100, and the inverter allows for better compatibility with charging devices and electrical devices.

[0074] Secondly, please refer to Figure 1 , Figure 2 and Figure 4 This application provides a method for assembling an energy storage power source, comprising: 01: A battery module 30 is provided, the battery module 30 including a first end 301 and a second end 302 opposite to each other; 03: The first end 301 of the battery module is locked to the top wall 111 of the first housing 11 using a locking device; and, 05: The second shell 13 is joined to the peripheral sidewall 113 of the first shell 11 to seal the accommodating cavity 15.

[0075] In the above embodiments, 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 are all defined as described above, and will not be repeated here.

[0076] Specifically, at least one battery cell 371 is first installed on the first bracket 31. Then, the second bracket 33 is connected to the first end 3101 of the first bracket, and 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 a battery module 30.

[0077] Next, align the battery module 30 with the mounting position, and then pass 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 housing 11.

[0078] Finally, the openings on the side of the peripheral wall 113 of the first shell 11 away from the top wall 111 are aligned with the openings of the second shell 13. Then, one or more combinations of welding, snap-fitting, and gluing are used to connect the second shell 13 to the peripheral wall 113 of the first shell 11 to seal the shell 10 and close the accommodating cavity 15. The assembly of the energy storage power supply 100 is completed.

[0079] Please refer to Figure 2 and Figure 4 In some embodiments, 01: A battery module 30 is provided, comprising: 011: At least one battery cell 371 is mounted 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 mounting groove 35 formed by the first bracket 31 and the second bracket 33 to form a battery module 30.

[0080] In the above embodiments, 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 described above, and will not be repeated here.

[0081] Specifically, firstly, the battery cell 371 is installed into the first insertion hole of the first bracket 31 to achieve precise installation of the battery cell 371 in the first bracket 31. Then, the first coupling 311 and the second coupling 331 are engaged, the second bracket 33 is aligned with the first bracket 31, and the battery cell 371 is simultaneously aligned with the second insertion hole. Therefore, at least one battery cell 371 is installed in the mounting groove 35, that is, sandwiched between the first bracket 31 and the second bracket 33, and the installation of the battery module 30 is completed.

[0082] Please refer to Figure 4 and Figure 5 In some embodiments, before step 05: joining the second shell 13 to the peripheral sidewall 113 of the first shell 11, the assembly method further includes: 04: The second end 302 of the battery module is connected to the peripheral sidewall 113 of the first shell 11 using the support member 50. The support member 50 is made of titanium alloy.

[0083] The support member 50 adopts the aforementioned definition and will not be repeated here. In the above embodiment, the first connecting part 51 is first aligned with the supporting part 1131, and the second connecting part 53 is aligned with the fixing part 315. Then, the first fixing member is used to connect the first connecting part 51 to the supporting part 1131, and the second fixing member is used to connect the second connecting part 53 to the fixing part 315, so as to connect the second end 302 of the battery module to the peripheral sidewall 113 through the support member 50, thereby further improving the structural stability and safety of the energy storage power supply 100.

[0084] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
