[0026] Please refer to Figures 1 to 4. In an embodiment of the present invention, the energy storage power supply 100 includes a housing 10 and a plurality of battery cells. A housing cavity 11 is provided inside the housing 10. A plurality of first fixing parts 1111 are provided on the inner wall 113 of the housing cavity 11. A first through-hole 1112 is provided on the bottom wall of the first fixing part 1111. There is a one-to-one correspondence between the plurality of battery cells 20 and the plurality of first fixing parts 1111. The battery cell 20 includes a body 21, a first pole 22 and a second pole 23. The first pole 22 and the second pole 23 are provided at both ends of the body 21 in the longitudinal direction. One end of the body 21 is housed in the first fixing part 1111. The first pole 22 is inserted through the first through-hole 1112.

[0027] In the above-described energy storage power supply 100, a first fixing component 1111 is provided on the inner wall 113 of the housing cavity 11, and one end of the main body 21 of the battery cell 20 is housed inside the first fixing component 1111. This allows the battery cell 20 to be directly attached to the first fixing component 1111, eliminating the need to assemble the battery module before inserting it into the housing 10. This reduces the assembly process and lowers costs, as well as reducing the number of parts required to assemble the battery module. Consequently, the space utilization rate of the product can be improved and the product size can be reduced.

[0028] In one embodiment, at least a portion of the housing 10 of the energy storage power supply 100 encloses a housing cavity 11, which is used to house a battery cell 20. The battery cell 20 may be cylindrical. The battery cell 20 may be placed vertically within the housing cavity 11, with its vertical orientation corresponding to the longitudinal direction of its body 21. Accordingly, a first fixing component 1111 is provided at the bottom of the housing cavity 11 to secure the bottom of the battery cell 20. It would also be understood that the first fixing component 1111 may be provided at the top of the housing cavity 11 to secure the top of the battery cell 20. The first fixing component 1111 may be integrally molded with the housing 10 or connected to the bottom of the inner wall 113 of the housing cavity 11 by other means of fixing connection, thereby securing the battery cell 20 relative to the housing 10. The first pole 22 and the second pole 23 of the battery cell 20 are the current interfaces during power supply or charging of the battery cell 20. The battery cell 20 includes the first pole 22 and the second pole 23, which are provided at both ends in the longitudinal direction of the main body 21, with the first pole 22 passing through the first through hole 1112. In other words, the battery cell 20 has two poles, one of which is passing through the first through hole 1112.

[0029] For two adjacent battery cells 20 with different electrical connection methods, the polarity of the first pole 22 and the second pole 23 may be different. When two adjacent battery cells 20 are connected in series, the first pole 22 of one of the battery cells 20 is positive and the second pole 23 is negative, while the first pole 22 of the other battery cell 20 is negative and the second pole 23 is positive. When two adjacent battery cells 20 are connected in parallel, the first pole 22 of one of the battery cells 20 is positive and the second pole 23 is negative, while the first pole 22 of the other battery cell 20 is positive and the second pole 23 is negative. One of the first pole 22 and the second pole 23 is connected to the first fixing component 1111. When the first fixing component 1111 is located at the bottom of the housing cavity 11, and the first pole 22 is the negative pole and the first pole 22 is connected to the first fixing component 1111, the first pole 22 can penetrate the housing 10 through the first through-hole 1112 on the first fixing component 1111 and be electrically connected to an external device. This establishes a port for supplying power to the outside or for charging the energy storage power supply 100. The number of first fixing components 1111 is kept to match the number of battery cells 20, so that each of the battery cells 20 is fixed within an individual first fixing component 1111. The first fixing component 1111 may be a circular groove, and the diameter of the first fixing component 1111 corresponds to the diameter of the battery cell 20, and the diameters of the two may be equal so that the battery cell 20 is fixed within the groove, or the diameter of the first fixing component 1111 may be slightly smaller than the diameter of the battery cell 20 to improve the strength of the fixation by interference matching. It will be understood that the first fixing component 1111 is set to a triangular, polygonal, or other irregular shape, and that the diameter of its maximum inner diameter circle is maintained so as to satisfy the above conditions. By making the diameter of the first through-hole 1112 less than or equal to the diameter of the first fixing component 1111, the battery cell 20 is prevented from sliding out of the first through-hole 1112. In this way, by reducing the number of structural components, the size and weight of the energy storage power supply 100 are reduced, the product structure and assembly process are optimized, the volumetric energy density and mass energy density of the product are improved, costs are reduced, and it becomes easier to carry.In some embodiments, the first fixing component 1111 may be a fixing groove that aligns with the battery cell 20, or it may be a clamp or clip that secures the battery cell 20.

[0030] In some other embodiments, the battery cell 20 may be a rectangular battery cell. If the battery cell 20 is a rectangular battery cell, the shape of the first fixing component 1111 will also be a corresponding rectangle. In some other embodiments, the battery cell 20 may be placed horizontally or in other orientations within the housing cavity 11. If the battery cell 20 is placed horizontally, the first fixing component 1111 may be provided on the front, rear, left, or right inner wall of the housing cavity 11 to fix the battery cell 20.

[0031] Please refer to Figure 5. In some embodiments, a first bracket 111 is provided on the inner wall of the housing cavity 11, and a plurality of first fixing components 1111 are provided on the first bracket 111.

[0032] In this way, the structure of the housing 10 can be simplified.

[0033] Please refer to Figure 5 for details. In one embodiment, a first bracket 111 may be provided at the bottom of the housing cavity 11, and a plurality of first fixing components 1111 may be provided on the first bracket 111. By assembling a plurality of first fixing components 1111 to the first bracket 111, the structure of the housing 10 can be simplified. The first bracket 111 may be welded to the housing 10 or be removably fixed using bolts or the like, and the flexibility of the energy storage power source 100 may be improved by replacing the first bracket 111 with one having a different number of first fixing components 1111 as needed.

[0034] In some embodiments, the first bracket 111 and the housing 10 are integrally molded.

[0035] In this way, the connection strength between the first bracket 111 and the housing 10 can be improved, and the manufacturing efficiency of the energy storage power supply 100 can be improved.

[0036] Specifically, in one embodiment, the first bracket 111 and the housing 10 are made of plastic, and the first bracket 111 and the housing 10 are manufactured integrally by an injection molding process, so that the first bracket 111 and the housing 10 can be made into an integrally molded structure.

[0037] In one embodiment, the first bracket 111 and the housing 10 may be made of metal, and the first bracket 111 and the housing 10 may be manufactured integrally by processes such as die casting and stamping, so that the first bracket 111 and the housing 10 can be made into an integrally molded structure.

[0038] Since the first bracket 111 and the housing 10 are integrally molded, there is no gap between the first bracket 111 and the housing 10, which in turn improves the connection strength between the first bracket 111 and the housing 10. By manufacturing the first bracket 111 and the housing 10 as an integral molded unit, the manufacturing efficiency of the energy storage power supply 100 can be improved.

[0039] Refer to Figure 5. In some embodiments, the energy storage power supply 100 includes a second bracket 112 located within the housing cavity 11. The second bracket 112 is connected to the inner wall of the housing cavity 11. The second bracket 112 is provided with a plurality of second fixing components (not shown). The bottom wall of the second fixing component is provided with a second through-hole 1121. There is a one-to-one correspondence between the plurality of battery cells 20 and the plurality of second fixing components. The other end of the main body 21 is housed in the second fixing component. The second pole column 23 is inserted through the second through-hole 1121.

[0040] In this way, the strength of the fixing of the battery cell 20 is improved.

[0041] Specifically, the second pole 23 of the battery cell 20 is inserted through the second through-hole 1121, and the first pole 22 is inserted through the first through-hole 1112. In other words, the battery cell 20 has two poles, and the two poles are inserted through the first through-hole 1112 and the second through-hole 1121, respectively.

[0042] For two adjacent battery cells 20 with different electrical connection methods, the polarity of the first pole 22 and the second pole 23 may be different. When two adjacent battery cells 20 are connected in series, the first pole 22 of one of the battery cells 20 is positive and the second pole 23 is negative, while the first pole 22 of the other battery cell 20 is negative and the second pole 23 is positive. When two adjacent battery cells 20 are connected in parallel, the first pole 22 of one of the battery cells 20 is positive and the second pole 23 is negative, while the first pole 22 of the other battery cell 20 is positive and the second pole 23 is negative.

[0043] Please refer to Figure 5. In one embodiment, when one end of the battery cell 20 is fixed by the first fixing component 1111 and the first pole 22 is inserted through the first through-hole 1112 of the first fixing component 1111, the second bracket 112 can fix the other end of the battery cell 20. When the first fixing component 1111 is provided at the bottom of the housing cavity 11, the second bracket 112 can be fixedly connected to the top of the housing cavity 11, thereby preventing the battery cell 20 from bending or flying out when the energy storage power supply 100 is subjected to disturbances such as vibration. The second fixing component is a circular groove corresponding to the diameter of the battery cell 20, and the diameters of the two may be the same, thereby fixing the battery cell 20 in the groove. The diameter of the second fixing component may be slightly smaller than the diameter of the battery cell 20, thereby improving the strength of the fixation by interference adjustment. The second fixing component can be set to a triangular, polygonal, or other irregular shape, and it will be understood that the diameter of its maximum inner circle is kept such that it satisfies the above conditions. By making the diameter of the second through-hole 1121 less than or equal to the diameter of the second fixing component, the battery cell 20 is prevented from sliding out of the second through-hole 1121. If the diameter of the first through-hole 1112 is smaller than the diameter of the first fixing component 1111, and the diameter of the second through-hole 1121 is smaller than the diameter of the second fixing component, both ends of the battery cell 20 may simultaneously contact the first fixing component 1111 of the first bracket 111 and the second fixing component of the second bracket 112, thereby further strengthening the fixing strength of the battery cell 20.

[0044] In some embodiments, the shape of the second fixing component may be rectangular, corresponding to the cross-sectional shape of the battery cell 20. Furthermore, when the battery cell 20 is placed horizontally or in other directions within the housing cavity 11, the first bracket 111 and the second bracket 112 may also be provided on the corresponding inner walls 113 within the housing cavity 11, each serving to secure one end of the battery cell 20. In other embodiments, it will be understood that the battery cell 20 may be placed at various angles within the housing cavity 11, thereby allowing for adjustment of the positions of components connected to the battery cell 20. Further details will not be repeated.

[0045] Please refer to Figure 2. In some embodiments, the first bracket 111 includes a plurality of support columns 1115, which are fixedly connected to the second bracket 112.

[0046] In this way, the strength of the fixing of the battery cell 20 is improved.

[0047] Please refer to Figure 2 for details. In one embodiment, a support column 1115 on the first bracket 111 extends along the height direction of the energy storage power source 100 to the second bracket 112 and connects to the second bracket 112, and the support column 1115 may be provided with screw holes. The second bracket 112 may include screw parts for screwing into the screw holes, and as a result, the first bracket 111 is fixedly connected to the second bracket 112 by the engagement of the screw threads, and both ends of the battery cell 20 are sandwiched and fixed in place. The first bracket 111 may also include a base plate which is the structural main body of the first bracket 111. The support column 1115 may be integrally molded with the base plate or fixedly connected to the base plate by means of screw thread connection or the like. In another embodiment, the support column 1115 may also be fixedly connected to the second bracket 112 by means of fasteners, pins or the like.

[0048] Refer to Figure 6. In some embodiments, the first bracket 111 includes an enclosure wall 1113 connected to the inner wall 113 of the housing cavity 11. The enclosure wall 1113 forms a housing groove 1114, which communicates with a plurality of first fixing components 1111.

[0049] In this way, the strength of the fixing of the battery cell 20 is improved.

[0050] Please refer to Figure 6 for details. In one embodiment, the first bracket 111 can provide a surrounding wall 1113 around the battery cell 20 along the length of the body 21 of the battery cell 20, with the height of the surrounding wall 1113 being less than the length of the battery cell 20. Along the length of the body 21 of the battery cell 20, there are openings at both the top and bottom ends of the surrounding wall 1113, and the first fixing part 1111 of the first bracket 111 closes one of the openings. The surrounding wall 1113 and the first fixing part 1111 of the first bracket 111 surround each other to form a storage groove 1114, which is enclosed within a housing cavity 11.

[0051] Please refer to Figure 6. In some embodiments, a fixing gel is injected into the storage groove 1114, and the fixing gel fixes and connects the battery cell 20 and the first bracket 11.

[0052] In this way, the safety of the battery cell 20 can be improved.

[0053] After the battery cell 20 is placed in the storage groove 1114, the battery cell 20 seals the first through-hole 1112 of the first fixing part 1111, thereby sealing the sides of the storage groove 1114 except for the top. At the top of the storage groove 1114, while keeping the opening facing upward, fixing gel is injected into the storage groove 1114. After the fixing gel has solidified, the first bracket 111 and the battery cell 20 can be placed in the housing cavity 11 in an inclined or horizontal position. The fixing gel may have some adhesiveness, thereby reducing the degrees of freedom of the battery cell 20 by several. Alternatively, the fixing gel may not have adhesiveness, which will reduce the degrees of freedom of the battery cell 20 by two. The combined use of the fixing gel and the first fixing part 1111 can further enhance the strength of the fixing and shock absorption capacity of the battery cell 20.

[0054] In some embodiments, the fixing gel may be a structural adhesive. Structural adhesives can withstand heavy loads. By injecting structural adhesive into the storage groove 1114, the impact resistance of the battery cell 20 can be enhanced. If the housing 10 of the energy storage power supply 100 is damaged and directly impacts the battery cell 20, the structural adhesive will withstand some of the impact force and transmit that force to the entire battery cell 20, mitigating the damage from the impact. Furthermore, structural adhesives have excellent corrosion resistance, and even if electrolyte leaks out of the battery cell 20 due to structural damage or if electrolyte is ejected from the explosion-proof valve (not shown) of the battery cell 20 due to thermal runaway, they can prevent further leakage of electrolyte and avoid corrosion of other battery cells 20 or other structural components.

[0055] Refer to Figures 5 and 6. In some embodiments, the energy storage power supply 100 includes a busbar assembly 30. The busbar assembly 30 includes a first busbar 31 and a second busbar 32. The first busbar 31 is connected to the first pole 22 of at least two battery cells 20. The second busbar 32 is connected to the second pole 23 of at least two battery cells 20.

[0056] In this way, the battery cell 20 becomes advantageous for supplying power to electrical devices as a single unit.

[0057] For specifics, please refer to Figures 5 and 6. In one embodiment, the energy storage power supply 100 can increase the versatility of its output current through a busbar assembly 30. The first poles 22 of the battery cell 20 are connected to the first busbar 31 through first through-holes 1112. The second poles 23 of the battery cell 20 can be directly connected to the busbar. The first busbar 31 can connect some of the first poles 22 of the battery cell 20, and the second busbar 32 can connect some of the corresponding second poles 23 of the battery cell 20, so that some of the battery cell 20 can output power outward or input power in parallel. The busbar assembly 30 may include a plurality of first busbars 31 and a plurality of second busbars 32, and the plurality of first busbars or second busbars can output power outward or input power in series or in parallel. The busbar assembly 30 may be made of copper, aluminum, nickel, or an alloy material. After the busbar assembly 30 is fixed in the correct position using a work jig, the busbar assembly 30 can be welded to the first pole 22 or second pole 23 of the battery cell 20 by laser welding. It will also be understood that the busbar assembly 30 can be electrically connected to the poles of the battery cell 20 by other connection methods such as twisting or crimping. In another embodiment, the energy storage power supply 100 further includes a second bracket 112, and the second pole 23 of the battery cell 20 can be connected to the second busbar 32 through a second through-hole 1121.

[0058] In another embodiment, the energy storage power supply 100 can also collect state information of each battery cell 20 through the collection assembly 40. The state information of the battery cells 20 may include information such as the voltage, current, and temperature of each battery cell 20. The collection assembly 40 may include a first collection plate 41 and a second collection plate 42. The first collection plate 41 is connected to a first busbar 31, and the second collection plate 42 is connected to a second busbar 32. After welding the first busbar 31 and the second busbar 32, the first collection plate 41 may be fixed to the corresponding position on the first busbar 31 and the second collection plate 42 may be fixed to the corresponding position on the second busbar 32 through screws. Once the collection assembly 40 is fixed, the nickel strip of the first collection plate 41 and the first busbar 31 may be connected by an electrical connection method such as laser welding, thereby achieving an electrical connection between the first collection plate 41 and the first busbar 31. At the same time, the second collection plate 42 and the second busbar 32 can also be connected in the same manner.

[0059] Refer to Figures 5 to 8. In some embodiments, the energy storage power supply 100 includes a cover plate 50. A siding groove is provided in the outer wall 12 of the housing 10 corresponding to the first fixing component 1111. A first through-hole 1112 penetrates the bottom wall of the siding groove 121, and a first busbar 31 is located in the siding groove 121. The cover plate 50 is provided on the outer wall 12 of the housing 10 and covers the siding groove 121.

[0060] This is advantageous in reducing the volume of the product.

[0061] For specifics, please refer to Figures 5 to 8. In one embodiment, the first housing 13 and the second housing 14 are connected to each other by bolts and surround each other to form a housing cavity 11. When the battery cell 20 is placed vertically within the housing cavity 11 and the first fixing part 1111 is provided at the bottom of the housing cavity 11, the housing groove 121 is also located at the bottom of the housing 10. The outer wall 12 at the bottom of the housing 10 is recessed inward to form the housing groove 121, and the outer wall 12 is, i.e., the bottom wall of the housing 10. The first pole 22 of the battery cell 20 enters the housing groove 121 through the first through-hole 1112 and the first fixing part 1111. The first busbar 31 may also be connected to the first pole 22 within the housing groove 121. This integrates the first pole 22 and the first busbar 31 at the bottom of the housing 10, increasing the overall degree of integration and reducing the volume of the product. The cover plate 50 is positioned to cover the housing groove 121, further enhancing the integrity of the housing 10 and protecting the first pole column 22 and the first busbar 31. The cover plate 50 is fixed to the housing 10 with bolts, but of course, it can be fixed by other methods and is not limited to this.

[0062] In the illustrated embodiment, the first bracket 111 and the first housing 13 are integrally molded.

[0063] In some embodiments, the cover plate 50 is connected to the housing 10 by adhesive (not shown) in the housing groove 121 and secured to the housing 10 by fasteners (not shown).

[0064] In this way, the cover plate 50 can be fixed in place.

[0065] Specifically, when fixing the cover plate 50, adhesive can be injected into the housing groove 121 first, then the cover plate 50 can be placed over it, and the cover plate 50 and the housing 10 can be connected with adhesive. Next, fasteners (for example, screws) can be attached and secured. The adhesive has the effect of temporarily fixing the cover plate 50 to the housing 10, and a certain degree of fixing effect of the fasteners to the cover plate 50 and the housing 10 can be ensured.

[0066] Please refer to Figures 5 to 8. In some embodiments, the energy storage power supply 100 includes a thermally conductive adhesive. The thermally conductive adhesive connects the cover plate 50 and the first busbar.

[0067] In this way, the temperature of the first busbar 31 can be lowered.

[0068] For specifics, please refer to Figures 5 to 8. In one embodiment, when current flows through the first busbar 31, a certain amount of current loss occurs, generating heat. The accumulated heat raises the temperature of the first busbar 31 and the battery cell 20, causing safety risks such as fire. Therefore, by filling the space between the first busbar 31 and the cover plate 50 with a thermally conductive adhesive, the heat from the first busbar 31 is transferred to the cover plate 50, and the heat is released into the surrounding environment through the cover plate 50, thereby providing a cooling effect to the first busbar 31 and the battery cell 20. The cover plate 50 may be made of aluminum, which has a relatively good heat transfer effect. Furthermore, the housing 10 can also be made of a material with good heat transfer properties, such as aluminum, which further transfers heat from the cover plate 50 to the housing 10, thereby enhancing the cooling effect to the first busbar 31 and the battery cell 20.

[0069] Please refer to Figures 5 and 6. In some embodiments, the energy storage power supply 100 further includes a sealing ring 60. The sealing ring 60 seals the cover plate 50 and the outer wall 12 of the housing 10.

[0070] In this way, the sealing effect of the accommodating groove 121 can be enhanced.

[0071] For specifics, please refer to Figures 5 and 6. In one embodiment, a housing groove 121 is formed in the outer wall 12 of the housing 10. A busbar assembly 30 is housed in the housing groove 121. In a humid operating environment, if the sealing effect of the housing groove 121 is poor, water vapor will enter the housing groove 121, causing the first busbar 31 to rust, or in the worst case, to cause a short circuit. Therefore, when the cover plate 50 covers the housing groove 121, a sealing ring 60 is provided between the cover plate 50 and the outer wall 12 of the housing 10 to further enhance the sealing effect of the housing groove 121 and isolate the busbar assembly 30 in the housing 121 from water vapor in the outside.

[0072] Refer to Figures 5 and 6. In some embodiments, the housing 10 includes a first housing 13 and a second housing 14. The first housing 13 is removably connected to the second housing 14 to form a housing cavity 11. A first fixing component 1111 is provided on either the first housing 13 or the second housing 14.

[0073] This makes installation and repair easier.

[0074] For specifics, please refer to Figures 5 and 6. In one embodiment, the housing 10 may include a first housing 13 located at the top and a second housing 14 located at the bottom, and the first fixing component 1111 may be provided on the first housing 13 or on the second housing 14. In some embodiments, the first housing 13 and the second housing 14 may be located at the front and rear or left and right sides of the housing 10, respectively, or at two diagonal corners of the housing 10. The first fixing component 1111 is provided on one of the first housing 13 and the second housing 14. In another embodiment, the first housing 13 and the second housing 14 may be removably connected to each other by means of screws, fasteners, or clamps. The first housing 13 and the second housing 14 form a housing cavity 11 that houses the battery cell 20. This improves the ease of assembly and disassembly / repair. In yet another embodiment, the energy storage power supply 100 further includes a second bracket 112. The first fixing component 1111 and the second bracket 112 may be connected to one of the first housing 13 and the second housing 14, respectively.

[0075] Please refer to Figures 5 and 6. In some embodiments, the first fixing component 1111 and the first housing 13 are connected as a single unit, or the first fixing component 1111 and the second housing 14 are connected as a single unit.

[0076] In this way, the overall strength is improved.

[0077] For specifics, please refer to Figures 5 and 6. In one embodiment, the first fixing component 1111 and the first housing 13 may be integrated into a single structure, thereby improving the overall integrity of the first fixing component 1111 and the housing 10. When transporting the energy storage power supply 100, the well-integrated housing 10 and first fixing component 1111 can reduce the shaking of the battery cells 20 relative to the housing 10, thereby reducing collisions and compression between internal structures such as the battery cells 20, and ensuring the safety of the energy storage power supply 100 during use. Of course, the first fixing component 1111 can also be connected to the second housing 14 as an integrated structure. In another embodiment, the energy storage power supply 100 further includes a second bracket 112. The first fixing component 1111 and the second bracket 112 can each be connected to one of the first housing 13 and the second housing 14 as an integrated structure.

[0078] In another embodiment, the first fixing part 1111 and the first housing 13 can be manufactured as an integrated structure using an injection molding process, or the first fixing part 1111 and the second housing 14 can be manufactured as an integrated structure.

[0079] See also Figure 1. In one embodiment, the energy storage power supply 100 may further include a panel 70 provided on the housing 10.
