[0040] Please refer to Figures 1 to 8. An energy storage power supply 100 provided in this application includes a housing 12, a battery cell 14, a second bracket 46, and an inverter 16. The housing 12 has a receiving cavity 18 and a receiving space, and a first bracket 20 is provided on the inner side of the receiving cavity 18. The first bracket 20 has a plurality of first receiving slots 28, and a first through hole 34 is provided at the bottom of the first receiving slot 28.

[0041] The battery cell 14 is located in the receiving cavity 18 and is mounted on the first support 20. Each battery cell 14 includes a body 30 and two poles, which are respectively located at both ends of the body 30 along its length. One end of the body 30 is fitted into a corresponding first receiving groove 28 and communicates with the receiving space through a first through hole 34.

[0042] The second bracket 46 is disposed within the receiving cavity 18 and fixedly connected to the housing 12. The second bracket 46 is disposed on the side of the battery cell 14 opposite to the first bracket 20, and the battery cell 14 is sandwiched between the first bracket 20 and the second bracket 46. The inverter 16 is located within the receiving cavity 18 and is electrically connected to the battery cell 14.

[0043] In the aforementioned energy storage power supply 100, a first support 20 is provided on the inner surface of the housing 12 facing the receiving cavity 18, and the battery cell 14 is disposed on the first support 20. Thus, the housing 12 can integrate support functionality, which can reduce the size and weight of the energy storage power supply 100 to a certain extent, improving its portability and reducing its manufacturing cost. Simultaneously, the battery cell 14, through the first support 20, can distribute the overall stress to the entire housing 12, reducing localized stress concentration and thereby improving the product's impact resistance to a certain degree.

[0044] Specifically, the housing 12 is used to enclose electrical components such as the battery cell 14 and the inverter 16. The material of the housing 12 includes, but is not limited to, plastic and metal. Optionally, in the embodiments of this application, the housing 12 includes a first housing 22 and a second housing 24. In Figures 3 to 9, the housing 12 has an upper and lower structure, with the first housing 22 being the lower housing of the energy storage power supply 100 and the second housing 24 being the upper housing of the energy storage power supply 100. In some embodiments, the first housing 22 may be the lower housing of the energy storage power supply 100, and the second housing 24 may be the upper housing of the energy storage power supply 100. In some embodiments, the housing 12 may have a left and right structure, with the first housing 22 being either the left or right housing of the energy storage power supply 100, and the second housing 24 being either the right or left housing of the energy storage power supply 100.

[0045] In the illustrated embodiment, both the first shell 22 and the second shell 24 are hollow structures with openings on one side. The opening side of the first shell 22 connects to the opening side of the second shell 24 so that the first shell 22 and the second shell 24 together define the receiving cavity 18. In other embodiments, one of the second shell 24 and the first shell 22 can be a hollow structure with an opening at one end, and the other can be a plate-like structure. The plate-like shell covers the opening side of the hollow shell so that the first shell 22 and the second shell 24 together define the receiving cavity 18. The shape of the shell 12 includes, but is not limited to, a cylinder, a cuboid, etc.

[0046] Optionally, in one embodiment, referring to FIG6, the first shell 22 and the first bracket 20 are integrally formed. In one example, the shell 12 is made of plastic. The first shell 22 and the first bracket 20 can be integrally manufactured using an injection molding process, thereby reducing the assembly steps of the first shell 22 and the first bracket 20 and increasing the connection strength between the first shell 22 and the first bracket 20.

[0047] Optionally, in one embodiment, the first shell 22 and the first bracket 20 can be separate structures. After the first shell 22 and the first bracket 20 are manufactured separately, the first bracket 20 is then fixed inside the first shell 22.

[0048] The battery cell 14 can be disposed within the receiving cavity 18, and the casing 12 can protect the battery cell 14. The battery cell 14 can be a secondary battery or a primary battery. The battery cell 14 can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery cell 14 can be cylindrical, flat, cuboid, or other shapes. In Figure 7, the battery cell 14 is cylindrical.

[0049] The cavity 18 contains one or more battery cells 14. The multiple battery cells 14 can be electrically connected in series, parallel or mixed connection. Mixed connection can mean that the multiple battery cells 14 are connected in both series and parallel.

[0050] In Figure 6, the inverter 16 is located on the side of the battery cell 14 facing away from the first support 20. The inverter 16 is housed within the receiving cavity 18, and the housing 12 provides protection for the inverter 16. The inverter 16 is electrically connected to the battery cell 14 and can convert the direct current (DC) power from the battery cell 14 into alternating current (AC) power to supply power to appliances that use AC power. Optionally, the energy storage power supply 100 can also output DC power to supply power to electronic devices that use DC power.

[0051] Referring to Figures 1 and 2, the energy storage power supply 100 includes a panel 26, which is mounted on the outer side of the housing 12 away from the receiving cavity 18. The panel 26 is equipped with, but is not limited to, input interfaces, output interfaces, a switch button, a display screen, and a light. Output interfaces include AC (alternating current) output ports, DC (direct current) output ports, car charger output ports, and USB output ports. Input interfaces include AC input ports and DC input ports. The switch button is used to turn the corresponding input interface on / off. The energy storage power supply 100 can be powered by an external power source (such as mains power, photovoltaic power, DC power, etc.) (e.g., charging the battery cells 14). The display screen can display information such as the energy level, input power, and output power of the energy storage power supply 100. The light is used for illumination.

[0052] Optionally, in one embodiment, the energy storage power supply 100 of this application can be applied to outdoor power sources for users to use outdoors. For example, when camping, users can use the energy storage power supply 100 to power and charge electrical appliances, lights, mobile phones, tablets, etc.

[0053] Optionally, in one embodiment, the energy storage power supply 100 of this application can be applied to an indoor power source for use by users indoors. For example, users can use an external power source to charge the energy storage power supply 100. If the power is interrupted in a user's home, the energy storage power supply 100 can be used to power appliances, lights, mobile phones, tablets, etc.

[0054] The main body 30 may include a housing and an electrode assembly located within the housing. The electrode assembly may be the component in the battery cell 14 where the electrochemical reaction occurs. The electrode assembly may be formed by winding or stacking positive and negative electrode plates, with a separator provided between the positive and negative electrode plates. The positive electrode plate has a positive tab, and the negative electrode plate has a negative tab. The positive and negative tabs are connected to the two electrodes respectively via connecting tabs. The polarities of the two electrodes are opposite.

[0055] In Figure 6, the length of the main body 30 is vertical. The two poles are an upper pole and a lower pole, located at the upper and lower ends of the main body 30, respectively. The lower end of the main body 30 is fitted into a corresponding first receiving groove 28 and communicates with the receiving space through a first through hole 34.

[0056] Optionally, the multiple first receiving slots 28 are arranged in a matrix, thereby causing the multiple battery cells 14 to also be arranged in a matrix. This results in a more regular arrangement of the battery cells 14, which is beneficial for improving the space utilization of the energy storage power supply 100. The shape of the first receiving slots 28 is adapted to the shape of the main body 30, thereby more effectively fixing and limiting the battery cells 14. In Figure 6, the main body 30 is cylindrical, and the first receiving slots 28 are also correspondingly cylindrical.

[0057] The first receiving slot 28 can restrict the battery cell 14 to prevent the battery cell 14 from shaking during the use of the energy storage power supply 100, which would affect the normal use of the energy storage power supply 100.

[0058] The second bracket 46 can further enhance the stability of the battery cell 14. Specifically, referring to Figures 5, 6, and 8, the first bracket 20 and the second bracket 46 can clamp the battery cell 14 in the vertical direction, making the battery cell 14 more stably fixed in the receiving cavity 18. The inverter 16 can be located on the side of the second bracket 46 away from the battery cell 14, so that the inverter 16 can be fixed by the second bracket 46. This reduces the number of additional components for fixing the inverter 16, which can reduce the size and weight of the energy storage power supply 100 to a certain extent, improve the portability of the energy storage power supply 100, and reduce the manufacturing cost of the energy storage power supply 100.

[0059] In some embodiments, referring to FIG9, the energy storage power supply 100 includes a first busbar 32 disposed in the accommodating space. The first busbar 32 is connected to a first pole 36 through a first through hole 34. The first pole 36 is a pole disposed on one end of the main body 30 that is fitted into the first receiving groove 28.

[0060] Thus, multiple battery cells 14 can be electrically connected through the first busbar 32.

[0061] Specifically, in one embodiment, referring to FIG9, the first electrode portion 36 may pass through the first through hole 34 and be connected to the first busbar 32. In one embodiment, the first busbar 32 may pass through the first through hole 34 and be connected to the first electrode portion 36.

[0062] The first busbar 32 can electrically connect multiple first electrode portions 36 of multiple battery cells 14, thereby enabling the connection of the first electrode portions 36 of different battery cells 14, which is beneficial for forming series, parallel, or mixed connections of multiple battery cells 14. The first busbar 32 is located on the outer surface of the housing 12, which also facilitates the maintenance of the first busbar 32.

[0063] The material of the first bus 32 includes, but is not limited to, copper, aluminum, nickel, or alloy materials. Optionally, the first bus 32 can be connected to the first electrode 36 by welding (such as laser welding). In Figure 9, the first bus 32 is located at the bottom of the first housing 22.

[0064] The first electrode portion 36 can be either a positive electrode portion or a negative electrode portion. In one embodiment, among two adjacent battery cells 14, one of the first electrode portions 36 can be a positive electrode portion and the other first electrode portion 36 can be a negative electrode portion. In another embodiment, among two adjacent battery cells 14, one of the first electrode portions 36 can be a positive electrode portion and the other first electrode portion 36 can be a negative electrode portion.

[0065] In some embodiments, referring to Figure 9, the energy storage power supply 100 includes a cover plate 42, and the housing 12 is provided with a cavity 38 on the outer side of the first support 20. The cover plate is provided on the outer side of the housing 12 and covers the cavity 38 to form an accommodating space, and the first busbar 32 is provided in the accommodating space.

[0066] Therefore, the first busbar 32 can be protected.

[0067] Specifically, the first busbar 32 is connected to the first pole portion 36 through the first through hole 34. The first busbar 32 is disposed within the accommodating space, so that the housing 12 can protect the first busbar 32. Moreover, the first busbar 32 is recessed within the housing 12, making it difficult for the user to touch. In Figure 9, the cavity 38 is disposed on the bottom surface of the first housing 22.

[0068] In some embodiments, referring to Figure 9, the energy storage power supply 100 includes a first acquisition board 40, which is disposed in the accommodating space and is electrically connected to the first busbar 32.

[0069] Therefore, parameter information of the battery cell 14 can be collected, and the first acquisition board 40 can be protected.

[0070] Specifically, the first acquisition board 40 is electrically connected to the first busbar 32, thereby enabling the first acquisition board 40 to acquire parameter information of the battery cell 14 through the first busbar 32. The parameter information of the battery cell 14 includes, but is not limited to, information such as the temperature, voltage, and current of the battery cell 14. The energy storage power supply 100 may include a battery management circuit board 44, which is equipped with a battery management system (BMS). The BMS can be electrically connected to the first acquisition board 40, thereby enabling the first acquisition board 40 to acquire parameter information of the battery cell 14.

[0071] The material of the first acquisition plate 40 includes, but is not limited to, copper, aluminum, nickel, or alloy materials. Optionally, the first acquisition plate 40 can be welded (e.g., laser welding) to the first busbar 32. In Figure 9, the first acquisition plate 40 is located at the bottom of the first housing 22.

[0072] Optionally, the energy storage power supply 100 includes a sealing ring (not shown) that seals the edges of the connecting cover plate 42 and the cavity 38, thereby improving the sealing performance of the accommodating space. Additionally, the cavity 38 is recessed into the surface of the housing 12, which prevents direct contact and damage between the first busbar 32 and the first acquisition plate 40 and external objects during assembly.

[0073] In some embodiments, referring to Figure 9, the second bracket 46 is provided with a plurality of second receiving slots 48, and the other end of the main body 30 is fitted into a corresponding second receiving slot 48.

[0074] Specifically, referring to Figures 3, 6 and 9, the lower end of the main body 30 is fitted into a corresponding first receiving groove 28, and the upper end of the main body 30 is fitted into a corresponding second receiving groove 48, so that the battery cell 14 can be limited in the first receiving groove 28 and the second receiving groove 48.

[0075] Optionally, the multiple second receiving slots 48 are arranged in a matrix, thereby causing the multiple battery cells 14 to also be arranged in a matrix. This results in a more regular arrangement of the battery cells 14, which is beneficial for improving the space utilization of the energy storage power supply 100. The shape of the second receiving slots 48 is adapted to the shape of the main body 30, thereby more effectively fixing and limiting the battery cells 14. In Figure 9, the main body 30 is cylindrical, and the second receiving slots 48 are also correspondingly cylindrical.

[0076] The second receiving slot 48 can restrict the battery cell 14 to prevent the battery cell 14 from shaking during the use of the energy storage power supply 100, which would affect the normal operation of the energy storage power supply 100. The first receiving slot 28 and the second receiving slot 48 can be arranged correspondingly in the vertical direction.

[0077] In some embodiments, referring to FIG8, the energy storage power supply 100 includes a second busbar 50 located in the receiving cavity 18, and a second through hole 52 is provided on the bottom surface of the second receiving groove 48. The second busbar 50 is connected to a second pole part 54 through the second through hole 52. The second pole part 54 is a pole part provided on one end of the main body 30 that is fitted into the second receiving groove 48.

[0078] Therefore, multiple battery cells 14 can be electrically connected through the second bus 50.

[0079] Specifically, in one embodiment, referring to FIG8, the second electrode portion 54 may pass through the second through hole 52 and be connected to the second busbar 50. In one embodiment, the second busbar 50 may pass through the second through hole 52 and be connected to the second electrode portion 54.

[0080] The second busbar 50 can electrically connect multiple second electrode portions 54 of multiple battery cells 14, thereby enabling the connection of the second electrode portions 54 of different battery cells 14, which is beneficial for forming series, parallel or mixed connections of multiple battery cells 14.

[0081] The material of the second bus 50 includes, but is not limited to, copper, aluminum, nickel, or alloy materials. Optionally, the second bus 50 can be connected to the second electrode 54 by welding (such as laser welding).

[0084] In some embodiments, referring to FIG8, the energy storage power supply 100 includes a second acquisition board 56 located within the receiving cavity 18, and the second acquisition board 56 is electrically connected to the second busbar 50.

[0085] Therefore, parameter information of the battery cell 14 can be collected.

[0086] Specifically, the second acquisition board 56 is electrically connected to the second busbar 50, thereby enabling the second acquisition board 56 to acquire parameter information of the battery cell 14 through the second busbar 50. The parameter information of the battery cell 14 includes, but is not limited to, information such as the temperature, voltage, and current of the battery cell 14. The BMS can be electrically connected to the second acquisition board 56, thereby enabling the second acquisition board 56 to acquire parameter information of the battery cell 14.

[0087] The material of the second acquisition board 56 includes, but is not limited to, copper, aluminum, nickel, or alloy materials. Optionally, the second acquisition board 56 can be connected to the second bus 50 by welding (such as laser welding).

[0088] In some embodiments, referring to Figures 5, 6 and 8, the energy storage power supply 100 includes a battery management circuit board 44, which is disposed in the receiving cavity 18. A first busbar 32 is electrically connected to the battery management circuit board 44, and an inverter 16 is disposed on the side of the battery management circuit board 44 away from the first busbar 32.

[0089] Therefore, the battery management circuit board 44 can collect parameter information of the battery cell 14 through the first bus 32.

[0090] Specifically, the battery management circuit board 44 includes a battery management system (BMS), which can be electrically connected to the first busbar 32. In this embodiment, the battery management circuit board 44 can be electrically connected to the first busbar 32 via the first acquisition board 40, thereby acquiring parameter information (including but not limited to voltage, current, temperature, etc.) of the battery cells 14. The BMS can control the operation of the energy storage power supply 100 based on the parameter information of the battery cells 14. Optionally, the battery management circuit board 44 is fixedly connected to the second bracket 46 by bolts.

[0091] Optionally, the battery management circuit board 44 can be electrically connected to the second bus 50 via the second acquisition board 56, thereby acquiring parameter information (including but not limited to voltage, current, temperature, etc.) of the battery cell 14.

[0092] Optionally, the energy storage power supply 100 includes an insulating sheet 58, which is disposed between the battery management circuit board 44 and the second busbar 50, and between the battery management circuit board 44 and the second acquisition board 56. This ensures, to a certain extent, insulation between the battery management circuit board 44 and the second busbar 50 and the second acquisition board 56. The insulating sheet 58 may be made of insulating material or have an insulating layer coated on its surface. Insulating materials include, but are not limited to, plastics, mica sheets, etc.

[0093] Optionally, the battery management circuit board 44 includes two first connectors, the second acquisition board 56 is provided with a second connector, and the first acquisition board 40 is provided with a third connector. The first connector can connect one first connector and the second connector, and the second connector can connect the other first connector and the third connector, thereby forming an electrical connection path.

[0094] In some embodiments, the sidewall of the receiving cavity 18 is also provided with a third through hole 57, which connects the receiving space and the receiving cavity 18, and the first busbar 32 is electrically connected to the battery management circuit board 44 through the third through hole 57.

[0095] Therefore, the third through hole 57 facilitates the routing of internal wiring in the housing 12 to electrically connect the first busbar 32 to the battery management circuit board 44.

[0096] Specifically, referring to Figure X, the third through hole 57 is located on the bottom surface of the receiving cavity 18. The first acquisition board 40 is electrically connected to the first busbar 32. The first acquisition board 40 can be electrically connected to the battery management circuit board 44 through the third through hole 57.

[0097] For example, the first acquisition board 40 is provided with a third connector, which can extend into the third through hole 57. One end of the second connector can be connected to the third connector through the third through hole 57, and the other end can be connected to the first connector of the battery management circuit board 44, thereby realizing the electrical connection between the first busbar 32 and the battery management circuit board 44.

[0098] The first busbar 32 is electrically connected to the battery management circuit board 44 through the third through hole 57. The side wall of the receiving cavity 18 is provided with the third through hole 57, which makes full use of the space of the energy storage power supply 100 and helps to improve the space utilization rate of the energy storage power supply 100.

[0099] In some embodiments, the first pole portion 36 is further provided with an explosion-proof valve 59, which is connected to the accommodating space through the first through hole 34.

[0100] Therefore, when the battery cell 14 experiences thermal runaway, the substance ejected from the explosion-proof valve 59 can be sprayed into the containment space through the first through hole 34, which can prevent the spread of thermal runaway to a certain extent.

[0101] Specifically, during operation, the battery cell 14 may release gas, causing an increase in internal pressure. When the pressure is high, the explosion-proof valve 59 can rupture to release substances (such as gas or liquid) inside the battery cell 14. The explosion-proof valve 59 is connected to the accommodating space through the first through-hole 34. The substance ejected from the explosion-proof valve 59 can be injected into the accommodating space, which isolates the substance from the other battery cells 14 within the accommodating cavity. This, to a certain extent, prevents the thermal runaway of one battery cell 14 from spreading to other battery cells 14, thus improving the safety of the energy storage power supply 100.

[0102] In some implementations, the inverter 16 is disposed on the side of the second bracket 46 opposite to the battery cell 14.

[0103] This reduces the number of components in the energy storage power supply.

[0104] Specifically, referring to Figures 5, 6, and 8, the first bracket 20 and the second bracket 46 can clamp the battery cell 14 in the vertical direction. The inverter 16 is located on the side of the second bracket 46 opposite to the battery cell 14, so the second bracket 46 can be used to fix the inverter 16, which can reduce the number of additional components for fixing the inverter 16, and can reduce the size and weight of the energy storage power supply 100 to a certain extent, thereby improving the portability of the energy storage power supply 100 and reducing the manufacturing cost of the energy storage power supply 100.

[0105] In some embodiments, referring to Figures 5, 6 and 8, a plurality of connectors 60 protrude from one side of the second bracket 46 away from the battery cell 14, and the inverter 16 is mounted on the plurality of connectors 60.

[0106] This increases the heat dissipation space for inverter 16.

[0107] Specifically, when the inverter 16 is working, it can convert the DC power output from the battery cell 14 into AC power and output it externally. During this process, the inverter 16 generates a significant amount of heat, requiring heat dissipation. The inverter 16 is mounted on multiple connectors 60, which allows it to be relatively far from the battery management circuit, thus increasing the heat dissipation space of the inverter 16.

[0108] Alternatively, the inverter 16 can be mounted on the connector 60 by means of bolts, clips, or other means.

[0109] Optionally, multiple connectors 60 form a receiving space 62, in which the battery management circuit board 44 and the separator 58 are located, which helps to improve the space utilization of the energy storage power supply 100.

[0110] In some embodiments, referring to Figure 3, the first bracket 20 is provided with a first connector 64, and the second bracket 46 is provided with a second connector 66. The first connector 64 and the second connector 66 are connected so that the first bracket 20 and the second bracket 46 clamp the battery cell 14.

[0111] Therefore, the structural strength of the connectors can be guaranteed to a certain extent.

[0112] Specifically, both the first connector 64 and the second connector 66 are elongated strips. The length of the first connector 64 extends towards the direction closer to the second bracket 46, and the length of the second connector 66 extends towards the direction closer to the first bracket 20. The first connector 64 and the second connector 66 can be connected by means including but not limited to bolts, clips, etc. In Figure 3, the first connector 64 and the second connector 66 are connected by bolts.

[0113] Optionally, the number of first connectors 64 and second connectors 66 is the same, and there are multiple of each. Multiple first connectors 64 are arranged along the edge of the first bracket 20, and multiple second connectors 66 can be arranged along the edge of the second bracket 46. Each first connector 64 is connected to a corresponding second connector 66, thereby increasing the connection stability of the first bracket 20 and the second bracket 46.

[0114] Compared to the case where the connector extends only from the first bracket 20 or the second bracket 46, resulting in a longer overall length of the connector and affecting its strength, in this embodiment, the first bracket 20 and the second bracket 46 are connected by a first connector 64 and a second connector 66. The lengths of the first connector 64 and the second connector 66 can be shorter, thereby ensuring the structural strength of the connector to a certain extent.

[0115] Optionally, the first connector 64 and the second connector 66 can be detachably connected.

[0116] In some embodiments, referring to Figure 6, the housing 12 includes a first housing 22 and a second housing 24, the first housing 22 is connected to the second housing 24, and the first bracket 20 is integrally formed with the first housing 22.

[0117] This can improve the stability of the fixed battery cell 14 to a certain extent.

[0118] Specifically, one end of the battery cell 14 is mounted on the first bracket 20. The first bracket 20 and the first shell 22 are integrally formed, and the connection between the first bracket 20 and the first shell 22 is relatively stable, which can improve the stability of fixing the battery cell 14 to a certain extent.

[0119] Alternatively, the housing 12 can be made of plastic, and the first housing 22 and the first bracket 20 can be manufactured integrally by injection molding, thereby improving efficiency and reducing costs.

[0120] In some embodiments, a handle 97 is provided on the second housing 24.

[0121] This makes it convenient for users to move the energy storage power supply 100.

[0122] Specifically, the energy storage power supply 100 can be moved and placed in different locations. When users move the energy storage power supply 100, they can carry it by the handle 97, making it convenient for users to move the energy storage power supply 100.

[0123] Optionally, in one embodiment, referring to Figures 1 to 9, the handle 97 is a separate handle rotatably mounted on the second housing 24. Optionally, in one embodiment, the handle 97 is integrally formed with the second housing 24. The material of the handle 97 can be the same as or different from the material of the second housing 24.

[0124] In some embodiments, referring to Figures 3 to 7, a first connecting post 68 is provided inside the first shell 22, and a second connecting post 70 is provided inside the second shell 24. The first connecting post 68 and the second connecting post 70 are connected to connect the first shell 22 and the second shell 24.

[0125] Therefore, the structural strength of the connecting column can be guaranteed to a certain extent.

[0126] Specifically, both the first connecting post 68 and the second connecting post 70 are elongated strips. The length of the first connecting post 68 extends towards the direction closer to the second shell 24, and the length of the second connecting post 70 extends towards the direction closer to the first shell 22. The first connecting post 68 and the second connecting post 70 can be connected by means including but not limited to bolts, clips, etc.

[0127] Optionally, the number of first connecting posts 68 and second connecting posts 70 is the same, and there are multiple of each. Multiple first connecting posts 68 are arranged along the side wall of the first shell 22, and multiple second connecting posts 70 are arranged along the side wall of the second shell 24. Each first connecting post 68 is connected to a corresponding second connecting post 70, thereby increasing the connection stability of the first bracket 20 and the second bracket 46.

[0128] Compared to the case where the connecting column extends only from the first shell 22 or the second shell 24, resulting in a longer overall length of the connecting column and affecting its strength, in this embodiment, the first shell 22 and the second shell 24 are connected by the first connecting column 68 and the second connecting column 70. The lengths of the first connecting column 68 and the second connecting column 70 can be shorter, thereby ensuring the structural strength of the connecting column to a certain extent.

[0129] In some embodiments, referring to Figures 4 and 8, the first connecting post 68 has a first connecting hole 72, the second connecting post 70 has a second connecting hole 74, and the third connector (not shown) connects the first connecting post 68 and the second connecting post 70 through the first connecting hole 72 and the second connecting hole 74.

[0130] Therefore, the first connecting post 68 and the second connecting post 70 can be connected.

[0131] Specifically, in one embodiment, one of the first connecting hole 72 and the second connecting hole 74 can be a through hole and the other can be a screw hole. The third connector can include a bolt, which can pass through the through hole and connect to the screw hole, thereby connecting the first connecting post 68 and the second connecting post 70.

[0132] In one embodiment, the first connecting hole 72 and the second connecting hole 74 are both threaded holes, and the third connector may include a bolt, which can be connected to the threaded hole of the first connecting post 68 and the threaded hole of the second connecting post, thereby connecting the first connecting post 68 and the second connecting post 70.

[0133] In one embodiment, the first connecting hole 72 and the second connecting hole 74 are both through holes. The third connector may include a pin, which can pass through the through hole of the first connecting post 68 and the through hole of the second connecting post and be connected to the two through holes with an interference fit, thereby connecting the first connecting post 68 and the second connecting post 70.

[0134] Optionally, the first connecting post 68 and the second connecting post 70 can be detachably connected. Optionally, the first housing 22, the first connecting post 68, the first connector 64, and the first bracket 20 can be integrally formed. The second housing 24 and the second connecting post 70 can be integrally formed.

[0135] In some embodiments, referring to Figures 1 to 8, the energy storage power supply 100 includes a panel 26, and the housing 12 is provided with a first opening 76, with the panel 26 mounted at the first opening 76.

[0136] Therefore, the panel 26 can be separately molded from the housing 12, which can reduce the types of materials and improve the versatility of materials.

[0137] Specifically, panel 26 is provided with a current output port (such as an AC output port), and panel 26 is installed at the first opening 76. Panel 26 and housing 12 can be separately formed. Because the AC output ports of energy storage power supplies 100 vary from country to country, the main difference in appearance between energy storage power supplies 100 from different countries is at the panel 26 position, while other parts are basically the same. In the embodiment of this application, panel 26 can be separately formed, so that the housing 12 of energy storage power supplies 100 from different countries only needs to be designed and manufactured with different panels 26, without the need for different specifications of the entire housing 12. This can reduce the types of materials and improve the versatility of materials.

[0138] Optionally, panel 26 can be detachably mounted at the first opening 76 for easy panel maintenance. Optionally, in other embodiments, panel 26 may also be integrally formed with housing 12 (such as first housing 22 or second housing 24).

[0139] In this embodiment, the first housing 22 and the second housing 24 are arranged vertically, and the battery cell 14 is arranged vertically. The first housing 22, battery cell 14, second bracket 46, battery management circuit board 44, inverter 16, and second housing 24 are arranged sequentially from bottom to top. The panel 26 is disposed on the side of the energy storage power supply 100. The cover plate 42 is disposed at the bottom of the energy storage power supply 100 because there may be gaps at the joint between the cover plate 42 and the first housing 22, which would affect the appearance of the product. Disposing it at the bottom of the energy storage power supply 100 makes it less visible. In addition, the weight of the energy storage power supply 100 itself can strengthen the connection between the cover plate 42 and the second housing 24, enhancing the sealing performance.

[0141] Therefore, the panel 26 can be installed at the first opening 76 through the first connecting piece and the second connecting groove 84.

[0142] Specifically, in this embodiment, the first shell 22 and the second shell 24 are connected by a first connecting post 68 and a second connecting post 70.

[0143] Alternatively, fasteners can be used to secure the panel 26, making it less likely to fall off the housing 12.

[0144] Furthermore, the first connecting post 68 and the second connecting post 70 are provided with slots near the first opening 76, and the outer periphery of the panel 26 is provided with buckles. The panel 26 is snapped into the first opening 76 by connecting the buckles with the slots.

[0145] In some embodiments, the housing 12 is provided with a second opening 86, and the energy storage power supply 100 includes a ventilation plate 88, which is installed at the second opening 86.

[0146] This can improve the heat dissipation performance of the energy storage power supply 100 to a certain extent.

[0147] Specifically, the ventilation plate 88 is provided with ventilation holes, and the receiving cavity 18 of the housing 12 can be connected to the outside of the housing 12 through the ventilation holes, so that the air inside and outside of the housing 12 can circulate, thereby improving the heat dissipation performance of the energy storage power supply 100 to a certain extent.

[0148] In one embodiment, referring to Figures 4 and 7, the housing 12 includes a first housing 22 and a second housing 24. The first housing 22 is provided with a third groove 90, and the second housing 24 is provided with a fourth groove 92.

A first connecting post 68 is provided with a third connecting groove 94 near the second opening 86, and a second connecting post 70 is provided with a fourth connecting groove 96 near the second opening 86. The ventilation plate 88 is provided with two second connecting pieces, which are respectively inserted into the third connecting groove 94 and the fourth connecting groove 96 so that the ventilation plate 88 is installed at the second opening 86.

[0149] Referring to Figures 4 and 7, the energy storage power supply 100 is equipped with two ventilation fins 88, which are respectively located at the second openings 86 on the left and right sides of the housing 12. The energy storage power supply 100 includes two cooling fans 98 mounted on the inverter 16, one cooling fan 98 near the left ventilation fin 88 and the other cooling fan 98 near the right ventilation fin 88. Optionally, the two cooling fans 98 can blow air in the same direction, such as blowing air to the left during operation, forming an airflow from the right ventilation fin 88 to the left ventilation fin 88 inside the housing 12, dissipating heat from the electrical components (including but not limited to the inverter 16, battery cells 14, etc.) inside the housing 12. Optionally, the cooling fans 98 can also be mounted on the second bracket 46. This application does not specifically limit the number of cooling fans 98.

[0150] Furthermore, the first connecting post 68 and the second connecting post 70 are provided with slots near the second opening 86, and the outer periphery of the ventilation plate 88 is provided with buckles. The ventilation plate 88 is engaged with the second opening 86 by connecting the buckles with the slots.

[0151] In one embodiment, the ventilation fin 88 may be integrally formed with the first housing 22 or the second housing 24. In another embodiment, the ventilation fin 88 may be detachably installed at the second opening 86.
