During the assembly process, after the two battery brackets are connected to both ends of the battery cell, the assembled battery module is placed into the casing. This results in a large weight and volume of energy storage products, which increases the manufacturing cost of energy storage products. Utility Model Content

[0003] This application provides an energy storage power supply that can solve or improve the technical problem of increased component quantity, assembly complexity, and cost caused by opening holes in the energy storage power supply casing, placing electrical connection pieces in the openings, and then sealing the openings with a bottom shell.

The first electrical connector is electrically connected to the first end, and the first electrical connector electrically connected to the first end is disposed in the fixing slot. The inverter is disposed in the receiving cavity and is electrically connected to the battery cells.

[0005] In this way, by welding electrical connectors to the first end of the battery cell body and selecting nickel strips and flexible flat cables as the acquisition components for acquiring electrical signals, and then inserting the battery cell body into the fixing groove set on the side wall of the receiving cavity, the battery cell body is directly fixed to the side wall of the receiving cavity, reducing the bottom shell with sealing openings, and reducing the number of parts, assembly complexity and cost of the energy storage power supply.

[0006] In some embodiments, the energy storage power source includes a data acquisition unit that is electrically connected to the first electrical connector at the first and second ends of the battery cell body.

[0007] Thus, by setting up a data acquisition unit inside the energy storage power supply, the data acquisition unit can replace the first electrical connector at both ends of the data acquisition circuit board for electrical connection, thereby reducing the installation space required for the data acquisition circuit board and lowering costs.

[0008] In some embodiments, the acquisition element includes an acquisition nickel strip and a flexible flat cable, the flexible flat cable being electrically connected to the first electrical connector via the acquisition nickel strip.

[0009] Thus, due to the excellent flexibility and bendability of flexible flat cables, they can adapt to various complex spatial layouts and bending requirements. By selecting nickel strips and flexible flat cables as the acquisition components for electrical signals, a complex soldering process is eliminated, thereby reducing assembly complexity and simplifying the assembly process.

[0010] In some embodiments, the fixing groove has an opening, the flexible flat cable passes through the opening, and is electrically connected to the first electrical connector via the collecting nickel strip.

[0014] In some embodiments, the first electrical connector includes a plurality of first electrical connectors, and one first electrical connector electrically connects to the first end of a plurality of the battery cells.

[0015] In this way, by electrically connecting multiple battery cells, the electrical signals of multiple battery cells can be collected through a single electrical connector, saving on the number of parts and reducing costs.

[0016] In some embodiments, the energy storage power supply includes a fixed bracket disposed within the receiving cavity and connected to the side wall of the receiving cavity and the battery cell, respectively, so as to fix the battery cell to the housing.

[0017] In this way, by setting a fixed bracket to fix the battery cell to the casing, it is possible to prevent the battery cell from shifting or shaking inside the energy storage power supply, which is conducive to the normal operation of the battery cell during charging and discharging.

[0018] In some embodiments, the fixing bracket has a first fixing post on the side near the battery cell, and the side wall of the receiving cavity has a second fixing post. The first fixing post is connected to the second fixing post so that the fixing bracket is connected to the housing.

[0019] In this way, by setting the first and second fixing columns to connect the fixing bracket and the housing, the structural strength of the fixing bracket can be increased and disassembly can be convenient.

The second end is provided with one of the positive electrode and the negative electrode, and the first end is provided with the other of the positive electrode and the negative electrode. The second electrical connector and the battery cell are located on opposite sides of the fixed bracket. The fixed bracket is provided with a through hole, and the second end of the battery cell body is electrically connected to the second electrical connector.

[0021] Thus, by opening through holes in the fixed bracket, the battery cells and the second electrical connector located on both sides of the fixed bracket can be connected to fix the second electrical connector.

[0022] In some embodiments, the energy storage power supply includes a protection board, a third fixing post is provided on the side of the fixing bracket away from the battery cell, the protection board is connected to the third fixing post, and the data acquisition device included in the energy storage power supply is electrically connected to the protection board.

[0023] Thus, by setting a third fixing post, the protection board is connected to the third fixing post, thereby fixing the protection board to the fixing bracket and preventing the protection board from moving or shaking inside the energy storage power supply, which is beneficial for the protection board to monitor the operation of the battery cell.

[0024] In some embodiments, the inverter is fixed to the side of the mounting bracket away from the battery cell.

[0025] In this way, by fixing the inverter to the fixed bracket, the inverter is prevented from moving or shaking inside the energy storage power source, which is beneficial for the inverter to convert the current of the energy storage power source.

[0046] Please see Figures 1 to 4 An energy storage power supply 100 according to an embodiment of this application includes a housing 10, a plurality of battery cells 20, a first electrical connector 30, and an inverter 80. The housing 10 is provided with a receiving cavity 11, and the side wall of the receiving cavity 11 is provided with a plurality of fixing slots 51. The battery cell 20 includes a battery cell body 21, a positive electrode 22, and a negative electrode 23. At least one of the positive electrode 22 / or the negative electrode 23 is located at the first end 24 of the battery cell body 21, and the first end 24 of the battery cell body 21 is inserted into the fixing slot 51. The first electrical connector 30 is electrically connected to the first end 24, and the first electrical connector 30 electrically connected to the first end 24 is disposed in the fixing slot 51. The inverter 80 is disposed in the receiving cavity 11 and is electrically connected to the battery cell 20.

[0047] Thus, by welding the first electrical connector 30 to the first end 24 of the cell body 21 and selecting the nickel strip 41 and flexible flat cable 42 as the acquisition components 40 for acquiring electrical signals, and then inserting the cell body 21 into the fixing groove 51 provided on the side wall of the receiving cavity 11, the cell body 21 can be directly fixed on the side wall of the receiving cavity 11, thereby reducing the number of parts, assembly complexity and cost of the energy storage power supply 100.

[0048] Among them, the energy storage power supply 100 is a device that can store electrical energy, can be used as a mobile power source, can store a large amount of electrical energy, and can efficiently transmit the stored electrical energy to other electrical devices.

[0049] Specifically, the energy storage power supply 100 includes a housing 10, a battery cell 20, a first electrical connector 30, and an inverter 80. The housing 10 protects the internal components of the energy storage power supply 100, such as the battery cell 20, mainboard 90, protection board 70, and inverter 80. The housing 10 may include a first housing 12 and a second housing 13, with the first housing 12 connected to the second housing 13. For example, the first housing 12 can be connected to the second housing 13 by bolts or by clips.

[0050] The housing 10 is cylindrical in shape, thus forming a receiving cavity 11. The receiving cavity 11 can accommodate components such as the battery cell 20, the main board 90, the protection board 70, and the inverter 80. The inner wall of the receiving cavity 11 is provided with fixing grooves 51. There can be multiple fixing grooves 51, which match the number of battery cells 20, so that the battery cells 20 can extend into the fixing grooves 51.

[0051] In some embodiments, multiple fixing slots 51 can communicate with each other to form a clearance slot 160, a first electrical connector 30 can connect multiple battery cells 20, and the first electrical connector 30 can be disposed in the clearance slot 160.

[0052] In this way, by connecting multiple fixing slots 51 to form a clearance slot 160, multiple battery cells 20 disposed in the clearance slot 160 can be connected using a first electrical connector 30, thereby reducing the number of first electrical connectors 30 used, saving parts and reducing costs.

[0053] The battery cell 20 is capable of storing electrical energy and outputting electrical energy when needed, by converting electrical energy into chemical energy for storage and then converting the chemical energy back into electrical energy for release when needed. The number of battery cells 20 can be multiple, and is not limited here. Multiple battery cells 20 can be installed in the fixing slot 51, thereby fixing the battery cells 20. The battery cell 20 includes a cell body 21, a positive electrode 22, and a negative electrode 23. The cell body 21 is capable of storing chemical energy, and the positive electrode 22 and negative electrode 23 are capable of converting chemical energy into electrical energy. The cell body 21 includes a first end 24 and a second end 25 facing away from each other, with at least one of the positive electrode 22 and / or the negative electrode 23 located at the first end 24 of the cell body 21. Figure 3 and Figure 4 In the illustrated embodiment, the positive electrode 22 is disposed on the second end 25 of the cell body 21, and the negative electrode 23 is disposed on the first end 24 of the cell body 21. In some embodiments, the positive electrode 22 and the negative electrode 23 can be disposed on the first end 24 of the cell body 21 simultaneously, or the positive electrode 22 and the negative electrode 23 can be disposed on the second end 25 of the cell body 21 simultaneously.

[0054] It should be noted that the first end 24 of the cell body 21 is the end closer to the fixing slot 51, and the second end 25 of the cell body 21 is the end farther away from the fixing slot 51. The positive electrode 22 and negative electrode 23 of multiple cells 20 can be respectively set at the first end 24 and the second end 25, that is, a positive electrode 22 is provided on the first end 24 of a certain cell body 21, and a negative electrode 23 is provided on the first end 24 of a certain cell body 21. A positive electrode 22 is provided on the second end 25 of a certain cell body 21, and a negative electrode 23 is provided on the second end 25 of a certain cell body 21. When two adjacent cells 20 are connected in series, one cell body 21 has a positive electrode 22 on its first end 24 and a negative electrode 23 on its second end 25, and the other cell body 21 has a negative electrode 23 on its first end 24 and a positive electrode 22 on its second end 25. When two adjacent cells 20 are connected in parallel, both cell bodies 21 have a positive electrode 22 on their first end 24 and a negative electrode 23 on their second end 25. Multiple cells 20 can be connected together in series or in parallel to form a battery module, which can provide higher voltage or greater capacity to meet different energy storage needs.

[0055] The first electrical connector 30 is disposed on the first end 24 and the second end 25 of the cell body 21. The shape of the first electrical connector 30 disposed on the first end 24 is adapted to the shape of the fixing groove 51, so that the first electrical connector 30 can be fixed in the fixing groove 51. This allows the first electrical connector 30 to electrically connect the positive electrode 22 and the negative electrode 23 of multiple cells 20, enabling each cell 20 to be electrically connected to other cells 20, thereby establishing a current transmission path between the cells 20 and ensuring that the current can be efficiently transmitted between the cells 20 or within the battery module. The first electrical connector 30 can be a sheet of conductive metal or foil, capable of connecting multiple cells 20 to form an integral conductive structure. For example, the first electrical connector 30 can be a thin sheet made of copper, aluminum, or a copper-aluminum composite material, giving it good conductivity and mechanical strength. Some first electrical connectors 30 can be made using a multi-layer composite material method to ensure their weldability and conductivity.

[0056] The first electrical connector 30 can connect the positive electrode 22 and the negative electrode 23 of the battery cell 20 by welding. For example, the first electrical connector 30 can be melted and adhered to the positive electrode 22 and the negative electrode 23 of the battery cell 20 by spot welding, laser welding, or ultrasonic welding. Thus, the first electrical connector 30 can connect the positive electrode 22 and the negative electrode 23 of multiple battery cells 20, allowing multiple battery cells 20 to be connected in series or parallel to meet the voltage and capacity requirements of different energy storage power supplies 100.

[0057] In some embodiments, the number of first electrical connectors 30 may include multiples, which is not limited here, and one first electrical connector 30 can electrically connect the first ends 24 of multiple battery cells 20. For example, the shape of the first electrical connector 30 may be cross-shaped, so that the first electrical connector 30 can connect the first ends 24 of four battery cells 20. In this way, by electrically connecting multiple battery cells 20, the electrical signals of multiple battery cells 20 can be collected through one first electrical connector 30, saving the number of parts and reducing costs.

[0058] The energy storage power supply 100 includes an inverter 80, which can be a converter capable of converting DC power to AC power at fixed frequency and voltage or frequency and voltage regulation. For example, the inverter 80 can convert DC power (such as from a battery or storage battery) to AC power, or convert AC power to DC power, or convert low voltage to high voltage and high voltage to low voltage. The inverter 80 can be disposed within the housing cavity 11 and can be electrically connected to the battery cell 20, thereby converting the current generated by the battery cell 20.

[0059] Please see Figure 5 In some embodiments, the energy storage power supply 100 includes a data acquisition unit 40, which is electrically connected to a first electrical connector 30 at a first end 24 and a second end 25 of the cell body 21.

[0060] Thus, by setting up a data acquisition unit 40 inside the energy storage power supply 100, the data acquisition unit 40 can replace the first electrical connector 30 at both ends of the data acquisition circuit board and the battery cell 20 for electrical connection, thereby reducing the installation space of the data acquisition circuit board and reducing costs.

[0061] Specifically, the energy storage power supply 100 is equipped with a data acquisition unit 40, which can monitor battery parameter data such as voltage, temperature, and current of the battery cells 20 in the energy storage power supply 100 in real time. Based on the acquired battery parameter data, the energy storage power supply 100 can perform fine-grained management and control of the battery cells 20 to ensure that the charging and discharging process of the battery cells 20 is carried out under optimal conditions. For example, when the data acquisition unit 40 detects abnormal phenomena such as excessively high voltage or abnormal temperature in the battery cells 20, it can trigger an alarm to remind the operator to take appropriate measures, thereby preventing performance degradation or even safety risks to the energy storage power supply 100.

[0062] The acquisition unit 40 can be disposed at the first end 24 and the second end 25 of the battery cell body 21, and the acquisition unit 40 can be electrically connected to the first electrical connector 30. Since the first electrical connector 30 is connected to the positive electrode 22 and the negative electrode 23 of the battery cell 20, the acquisition unit 40 can acquire data from the positive electrode 22 and the negative electrode 23 of the battery cell 20.

[0063] In some embodiments, the collecting element 40 may be a collecting nickel strip 41 and a flexible flat cable 42. The flexible flat cable 42 may be made primarily of insulating material and extremely thin tin-plated flat copper wire, pressed together using high-tech automated production lines. The structure of the flexible flat cable 42 typically includes two layers of insulating foil with a flat copper foil sandwiched in between, forming a flat and flexible conductor. This gives the flexible flat cable 42 excellent flexibility and bendability, allowing it to adapt to various complex wiring needs in space-constrained environments. Furthermore, the thinness and small size of the flexible flat cable 42 help reduce the volume and weight of the energy storage power supply 100, lowering production costs. The connection and disassembly process of the flexible flat cable 42 is relatively simple, facilitating maintenance and replacement.

[0064] The flexible flat cable 42 can be electrically connected to the first electrical connector 30 via a nickel strip 41. The nickel strip 41 is made of a material with excellent conductivity and relatively low resistivity, thus effectively transmitting current and signals. Using the nickel strip 41 as a connection medium between the flexible flat cable 42 and the electrical connector ensures stable transmission of current and signals, meeting the high-performance connection requirements of electronic devices. Furthermore, the nickel strip 41 has good oxidation resistance, preventing oxidation and corrosion to a certain extent, thereby extending the service life of the flexible flat cable 42. Thus, due to its excellent flexibility and bendability, the flexible flat cable 42 can adapt to various complex spatial layouts and bending requirements. By selecting the nickel strip 41 and the flexible flat cable 42 as the acquisition component 40 for acquiring electrical signals, a complex soldering process is eliminated, reducing assembly complexity and simplifying the assembly process.

[0065] Please see Figure 5 Fun Figure 6 In some embodiments, the fixing groove 51 is provided with an opening 52, through which the flexible flat cable 42 passes and is electrically connected to the first electrical connector 30 via the collecting nickel strip 41.

[0066] Thus, by opening 52 in the fixed groove 51, a connection space for the flexible flat cable 42 can be provided, so that the flexible flat cable 42 can be electrically connected to the first electrical connector 30 to obtain the electrical signal of the battery cell 20.

[0067] Specifically, since the first electrical connector 30 is fixed in the fixing groove 51, the flexible flat cable 42 cannot be directly connected to the first electrical connector 30 during assembly. Therefore, by opening an opening 52 in the side wall of the fixing groove 51, the fixing groove 51 can be connected to the receiving cavity 11, and the flexible flat cable 42 can pass through the opening 52 and extend into the fixing groove 51 to connect with the first electrical connector 30. This allows the flexible flat cable 42 to replace the acquisition circuit board to obtain the battery parameter data of the cell 20, saving the installation space of the soldered acquisition circuit board, which is conducive to the miniaturization of the energy storage power supply 100. Furthermore, the flexible flat cable 42 is lighter and smaller than the acquisition circuit board, which helps to reduce the size and weight of the energy storage power supply 100.

[0068] Please see Figure 6 In some embodiments, the side wall of the receiving cavity 11 is provided with a limiting rib 50, the limiting rib 50 forms a fixing groove 51, the inner wall of the limiting rib 50 is provided with a bearing portion 53, and the first end 24 of the battery cell 20 is provided on the bearing portion 53 so that the first electrical connector 30 is embedded in the fixing groove 51.

[0069] Thus, by setting a limiting rib 50 on the side wall of the receiving cavity 11, the fixing groove 51 formed by the limiting rib 50 can fix the battery cell 20 and the first electrical connector 30, thereby saving the welding space of the first electrical connector 30 and reducing the assembly complexity.

[0070] Specifically, the sidewall of the receiving cavity 11 is provided with limiting ribs 50, which can be used to form a fixing groove 51 to fix the battery cell 20 and the electrical connecting piece that extend into the fixing groove 51. The housing 10 includes a first housing 12 and a second housing 13. The limiting ribs 50 can be integrally formed with the first housing 12 on the sidewall of the receiving cavity 11, or the limiting ribs 50 can be welded to the sidewall of the receiving cavity 11 of the first housing 12.

[0071] The number of limiting ribs 50 can be multiple, and these ribs 50 can be connected to each other to increase the structural strength of the limiting ribs 50. The limiting ribs 50 can form a quincunx structure, creating four fixing grooves 51 within each groove. Four battery cells 20 can be fixed within these grooves 51, and the electrical connector can be adapted to the shape of the limiting ribs 50, forming a cross-shaped structure to connect with the first ends 24 of the four battery cells 20. It should be noted that the inner wall of the limiting ribs 50 can be provided with a bearing portion 53. When a battery cell 20 extends into the fixing groove 51, its first end 24 rests on and is supported by the bearing portion 53, allowing the first electrical connector 30 connected to the first end 24 of the battery cell 20 to be embedded in the fixing groove 51.

[0072] Please refer to it again. Figure 2 In some embodiments, the energy storage power supply 100 includes a fixed bracket 60, which is disposed in the receiving cavity 11 and is connected to the side wall of the receiving cavity 11 and the battery cell 20 respectively, so as to fix the battery cell 20 to the housing 10.

[0073] Thus, by fixing the battery cell 20 to the housing 10 with the fixed bracket 60, it is possible to prevent the battery cell 20 from shifting or shaking inside the energy storage power supply 100, which is beneficial to the normal operation of the battery cell 20 during the charging and discharging process.

[0074] Specifically, the energy storage power supply 100 includes a fixing bracket 60, which is used to fix the second end 25 of the battery cell body 21, which is provided with a positive electrode 22 and a negative electrode 23. The housing 10 includes a first housing 12 and a second housing 13. The fixing bracket 60 is disposed within a receiving cavity 11 and can be connected to the inner wall of the receiving cavity 11 of the first housing 12. For example, the fixing bracket 60 has a first fixing post 61 on the side near the battery cell 20, and a second fixing post 111 on the side wall of the receiving cavity 11. The second fixing post 111 protrudes from the inner wall of the receiving cavity 11 of the first housing 12. The first fixing post 61 and the second fixing post 111 can be integrally formed with the fixing bracket 60, and can be integrally formed with the second housing 12. Thus, the first fixing post 61 and the second fixing post 111 can be connected to the inner wall of the receiving cavity 11 by bolts or snap-fit ​​connections. Thus, by setting the first fixing post 61 and the second fixing post 111 to connect the fixing bracket 60 and the housing 10, the structural strength of the fixing bracket 60 can be increased and it is easy to disassemble.

[0075] The second end 25 is disposed on the cell body 21 opposite to the first end 24. The fixing bracket 60 can be connected to the second end 25 of the cell 20. The energy storage power supply 100 includes a second electrical connector 150. For example, the second electrical connector 150 and the cell 20 can be disposed on opposite sides of the fixing bracket 60. By forming through holes 62 on the end face of the fixing bracket 60 facing the cell 20 to accommodate the cell body 21, and the number of through holes 62 is the same as the number of cells 20, the second end 25 of the cell body 21 with a positive electrode 22 or a negative electrode 23 can be embedded in the through hole 62, thereby fixing the cell body 21 to the fixing bracket 60. The second electrical connector 150 and the cell 20 can be disposed on opposite sides of the fixing bracket 60. The second end 25 of the cell body 21 can extend into the through hole 62 to facilitate connection with the second electrical connector 150, or the second electrical connector 150 can pass through the through hole 62 to connect with the second end 25 of the cell body 21. Thus, by fitting the battery cell body 21 into the through hole 62 of the fixing bracket 60, the battery cell 20 can be fixed without the need for pre-set installation space, which helps to reduce the size of the energy storage power supply 100. Furthermore, by opening the through hole 62 on the fixing bracket 60, the battery cell 20 disposed on both sides of the fixing bracket 60 and the second electrical connector 150 can be connected to fix the second electrical connector 150.

[0076] In some embodiments, when the second end 25 of the cell body 21, which has a positive electrode 22 and a negative electrode 23, extends into the through hole 62, it can be connected to the fixing bracket 60 by welding.

[0077] Please see Figure 2 In some embodiments, the energy storage power supply 100 includes a protection plate 70, a third fixing post 63 is provided on the side of the fixing bracket 60 away from the battery cell 20, the protection plate 70 is connected to the third fixing post 63, and the data acquisition component 40 included in the energy storage power supply 100 is electrically connected to the protection plate 70.

[0078] Thus, by setting the third fixing post 63, the protection plate 70 is connected to the third fixing post 63, thereby fixing the protection plate 70 to the fixing bracket 60, preventing the protection plate 70 from moving or shaking inside the energy storage power supply 100, which is beneficial for the protection plate 70 to monitor the operation of the battery cell 20.

[0079] Specifically, the energy storage power supply 100 includes a protection board 70, on which a battery management system is programmed. This protection board 70 can monitor and protect the operating status of the battery cells 20, ensuring their safe and efficient operation. For example, the protection board 70 can monitor key parameters of the energy storage power supply 100 in real time, such as voltage, current, and temperature. When the battery cells 20 experience potential risks such as overcharging, over-discharging, short circuits, overcurrent, or abnormal temperatures, the protection board 70 can automatically cut off the circuit to protect the battery cells 20 from damage, thereby extending the service life of the energy storage power supply 100.

[0080] The protection plate 70 can be fixed to the fixing bracket 60. For example, a third fixing post 63 is provided on the side of the fixing bracket 60 away from the battery cell 20. The third fixing post 63 and the fixing bracket 60 are integrally formed. There are multiple third fixing posts 63, so that the protection plate 70 can be bolted or welded to multiple third fixing posts 63.

[0081] The protection board 70 is provided with a wiring port, which is located on the edge of the protection board 70. The wiring port enables the acquisition component 40 included in the energy storage power supply 100 to be electrically connected to the protection board 70, so that the key parameters such as voltage, current and temperature of the energy storage power supply 100 acquired by the acquisition component 40 can be transmitted to the protection board 70.

[0082] Please see Figure 2 The inverter 80 is fixed to the side of the fixed bracket 60 away from the battery cell 20.

[0083] In this way, by fixing the inverter 80 to the fixed bracket 60, the inverter 80 is prevented from moving or shaking inside the energy storage power supply 100, which is beneficial for the inverter 80 to convert the current of the energy storage power supply 100.

[0084] Specifically, the inverter 80 can be fixedly connected to the mounting bracket 60. For example, a fourth fixing post 64 is provided on the side of the mounting bracket 60 away from the battery cell 20. The fourth fixing post 64 and the mounting bracket 60 are integrally formed, so that the inverter 80 can be bolted or welded to the fourth fixing post 64. Furthermore, the inverter 80 is provided with a communication interface, and a protection board 70 is located between the inverter 80 and the mounting bracket 60. The inverter 80 can be electrically connected to the protection board 70 through the communication interface, so that the protection board 70 can control the operation of the inverter 80 based on key parameters such as voltage, current, and temperature of the energy storage power supply 100.

[0085] Along the height of the energy storage power supply 100, the inverter 80 can be positioned above the battery cell 20 and the mounting bracket 60. This allows for more efficient use of the vertical space of the energy storage power supply 100, facilitates the natural dissipation of heat generated by the inverter 80, and makes integration with the heat dissipation system of the energy storage power supply 100 easier. When disassembling and installing the energy storage power supply 100, positioning the inverter 80 above the mounting bracket 60 in the height direction of the energy storage power supply 100 facilitates its installation and removal.

[0086] Please see Figure 2 and Figure 7 In some embodiments, the energy storage power supply 100 includes a main board 90, and the housing 10 includes a first housing 12 and a second housing 13. The first housing 12 is connected to the second housing 13, the main board 90 is connected to the second housing 13, and the main board 90 is electrically connected to the inverter 80 included in the energy storage power supply 100.

[0087] In this way, by connecting the motherboard 90 to the second housing 13, the motherboard 90 can be fixed, preventing the motherboard 90 from moving or shaking inside the energy storage power supply 100, which is beneficial for the motherboard 90 to connect to and control the inverter 80.

[0088] Specifically, the energy storage power supply 100 includes a main board 90, which controls, manages, and protects the energy storage power supply 100, and performs important functions such as energy conversion and distribution. The housing 10 includes a first housing 12 and a second housing 13, with the first housing 12 connectable to the second housing 13. For example, the first housing 12 can be connected to the second housing 13 by bolts or by clips. The main board 90 can also be connected to the second housing 13. For example, the main board 90 can be welded to the second housing 13 or bolted to it.

[0089] The motherboard 90 is electrically connected to the inverter 80 included in the energy storage power supply 100. For example, the motherboard 90 is provided with a communication interface, and the inverter 80 can be connected to the motherboard 90 by connecting the communication interface with a cable, so that the motherboard 90 can control the operation of the inverter 80.

[0090] Please see Figure 7 In some embodiments, the energy storage power supply 100 includes a handle 140, which includes a first handle 141 and a second handle 142. The first handle 141 is disposed on the outer wall of the first housing 12, and the second handle 142 is disposed on the outer wall of the second housing 13. The first housing 12 includes a fifth fixing post 121, and the second housing 13 includes a sixth fixing post 131. When the fifth fixing post 121 and the sixth fixing post 131 are connected, the first handle 141 and the second handle 142 are connected.

[0091] Thus, by setting the first handle 141 on the first housing 12 and the second handle 142 on the second housing 13, the first handle 141 and the second handle 142 can be automatically connected when the first housing 12 and the second housing 13 are connected, thereby reducing the number of parts and costs and simplifying the assembly process.

[0092] Specifically, the energy storage power supply 100 includes a handle 140, which helps the user move the energy storage power supply 100 when it needs to be moved. The handle 140 includes a first handle 141 and a second handle 142. The first handle 141 can be disposed on the outer wall of the first housing 12. For example, the first handle 141 and the first housing 12 are integrally formed, or the first handle 141 can be welded or bolted to the first housing 12.

[0093] The second handle 142 can be disposed on the outer wall of the second housing 13. For example, the second handle 142 and the second housing 13 are integrally formed, or the second handle 142 can be welded or bolted to the second housing 13. The first handle 141 can be disposed opposite to the second handle 142.

[0094] The first housing 12 includes a fifth fixing post 121, and the second housing 13 includes a sixth fixing post 131. The fifth fixing post 121 and the sixth fixing post 131 are disposed on the inner wall of the receiving cavity 11 of the first housing 12. The fifth fixing post 121 can be integrally formed with the first housing 12, and the sixth fixing post 131 can be integrally formed with the second housing 13. The fifth fixing post 121 and the sixth fixing post 131 are arranged opposite to each other, so that when the fifth fixing post 121 and the sixth fixing post 131 are connected, the first handle 141 can be connected with the second handle 142.
