Technical Field

[0001] This application relates to the field of energy storage equipment technology, and more specifically, to an energy storage power source. Background Technology

[0002] In related technologies, energy storage power supplies typically require multiple battery cells. To ensure the stability of these cells, they are usually assembled into a battery module using a bracket before being fixed inside the casing. This results in numerous components, large size, and high cost for energy storage power supplies. On the other hand, the bracket occupies a significant amount of space inside the energy storage power supply and, to some extent, limits further improvements in energy density and space utilization. Summary of the Invention

[0003] This application provides an energy storage power source to solve at least one of the aforementioned technical problems.

[0004] The energy storage power source according to the embodiments of this application includes:

[0005] A housing, wherein a first mounting cavity is formed inside the housing and a second mounting cavity is formed outside the housing;

[0006] Multiple battery cells are installed within the second mounting cavity;

[0007] A third housing, configured to close the second mounting cavity when the third housing is mounted on the housing;

[0008] An inverter, which is installed in the first mounting cavity and electrically connected to the plurality of battery cells.

[0009] This application provides an energy storage power supply that eliminates the need for traditional brackets by setting a second mounting cavity on the housing and fixing multiple battery cells in the second mounting cavity. This reduces the number of parts in the energy storage power supply, which is beneficial for reducing the size and cost of the energy storage power supply and further improving the energy density and space utilization of the energy storage power supply.

[0010] In some embodiments, the housing includes a first housing and a second housing, the first housing and the second housing being detachably connected, a second mounting cavity being disposed on the second housing, the first housing and the second housing forming a first mounting cavity, and the third housing being mounted on the second housing.

[0011] This facilitates the machining of the second mounting cavity and also facilitates the electrical connection between the battery cell and the electrical connector.

[0012] In some embodiments, the second housing and the third housing constitute part of the outer surface of the energy storage power source.

[0013] In this way, the battery cell is integrated with the casing. While protecting the internal structure of the energy storage power supply, the casing also serves as a traditional support structure, achieving multiple uses for the casing.

[0014] In some embodiments, a plurality of first positioning grooves are provided on the inner wall of the second mounting cavity, one end of the battery cell is inserted into the first positioning groove, and the third housing fixes one end of the battery cell to the first positioning groove.

[0015] Thus, the first positioning groove is used to fix the battery cell and prevent the battery cell from shifting when it is electrically connected to the electrical connector.

[0016] In some embodiments, the third housing is provided with a plurality of second positioning slots, and the other end of the battery cell is inserted into the second positioning slot.

[0017] Thus, the second positioning groove is used to fix the battery cell and prevent the battery cell from shifting when it is electrically connected to the electrical connector.

[0018] In some embodiments, the energy storage power supply further includes an electrical connector disposed in the first mounting cavity, and the plurality of battery cells are electrically connected to the electrical connector.

[0019] Thus, the electrical connector is located inside the first mounting cavity, which facilitates connection with the battery cell and helps to improve the space utilization rate inside the energy storage power supply.

[0020] In some embodiments, a plurality of openings communicating with the second mounting cavity are formed on the inner wall of the first mounting cavity, and the plurality of battery cells are electrically connected to the electrical connector through the openings.

[0021] Thus, the opening facilitates the electrical connection between the battery cell and the electrical connector.

[0022] In some embodiments, the battery cell includes a positive electrode and a negative electrode located at the same end of the battery cell, the positive electrode and the negative electrode communicating with the first mounting cavity through the opening, and the electrical connector connecting the positive electrode of the battery cell and the negative electrode of an adjacent battery cell.

[0023] In this way, the structure of the energy storage power supply is simplified by simply placing the opening and electrical connector on the same inner wall of the second mounting cavity, which also facilitates the installation and fixing of the battery cells.

[0024] In some embodiments, the opening includes a first opening and a second opening, the first opening and the second opening being respectively provided for the positive electrode and the negative electrode.

[0025] Thus, the first opening and the second opening correspond to the positive and negative terminals of the battery cell, respectively, making it easy to distinguish the connection of the electrical connectors.

[0026] In some embodiments, the housing is further provided with a partition, which is disposed on the surface of the second mounting cavity away from the battery cell and located between the first opening and the second opening.

[0027] In this way, the separator forms a barrier between the positive and negative terminals of the battery cell, preventing accidental contact of the electrical connectors when connecting the battery cell and causing a short circuit.

[0028] In some embodiments, the housing includes a plurality of first connecting posts located within the second mounting cavity, and the third housing includes a plurality of second connecting posts, wherein the first connecting posts are connected to the second connecting posts when the third housing is mounted on the housing.

[0029] Thus, the first connecting post and the second connecting post are used to connect the shell and the third shell, and the first connecting post helps to improve the structural strength of the shell, while the second connecting post helps to improve the structural strength of the third shell.

[0030] In some embodiments, the housing is provided with ventilation holes that allow the first mounting cavity to communicate with the outside.

[0031] In this way, the ventilation holes can be used to dissipate heat from the energy storage power supply, preventing the battery cells from thermally running away due to excessive internal temperature.

[0045] In related technologies, energy storage power supplies typically require multiple battery cells. To ensure the stability of these cells, they are usually assembled into a battery module using a bracket before being fixed inside the casing. This results in numerous components, large size, and high cost for energy storage power supplies. On the other hand, the bracket occupies a significant amount of space inside the energy storage power supply and, to some extent, limits further improvements in energy density and space utilization.

[0046] Please see Figure 1 This application provides an energy storage power supply 100, including a housing 10, a third housing 30, an inverter 60 and a plurality of battery cells 20. A first mounting cavity 111 is formed inside the housing 10, and a second mounting cavity 121 is formed outside the housing. The plurality of battery cells 20 are installed in the second mounting cavity 121. The third housing 30 is configured such that when the third housing 30 is installed on the housing 10, it closes the second mounting cavity 121.

[0047] This application provides an energy storage power supply 100. By providing a second mounting cavity 121 on the housing 10 and fixing multiple battery cells 20 using the second mounting cavity 121, the traditional bracket is eliminated, the number of parts of the energy storage power supply 100 is reduced, which is conducive to reducing the size of the energy storage power supply 100, reducing the cost of the energy storage power supply 100, and further improving the energy density and space utilization of the energy storage power supply 100.

[0048] For details, please refer to Figure 1and Figure 2 The energy storage power supply 100 is a device that can store electrical energy and release it when needed. Its main function is to provide a stable and reliable power supply. When the system needs to store electrical energy, the controller charges the battery pack, which converts the electrical energy into chemical energy for storage. When the system needs to use electrical energy, the controller first converts the DC power stored in the battery pack into AC power before outputting it.

[0049] In this embodiment, the energy storage power supply 100 also includes a motherboard 70, a panel 80, and a battery management system 90. Multiple battery cells 20 are connected in series or in parallel to form a battery pack. The battery pack is electrically connected to the motherboard 70 and the battery management system 90, respectively. The motherboard 70 is electrically connected to the panel 80. The panel 80 controls the energy storage power supply 100 to perform charging and discharging operations through the motherboard 70. The inverter 60 is connected to the battery pack through the battery management system 90 to convert the DC power of the battery pack into AC power.

[0050] The panel 80 includes, but is not limited to, an AC socket, a USB output port, a car charger output port, a display screen, operation buttons, and a light. The AC socket is used to output AC power, while the USB output port and the car charger output port are used to output DC power. The display screen can show information such as the power level, output power, and input power of the energy storage power supply 100. Users can input commands to the energy storage power supply 100 through the operation buttons, and the light can provide illumination.

[0051] A Battery Management System (BMS) 90 is a collection of hardware, software, and algorithms used to monitor, manage, and protect an energy storage power source 100. It is a key component of the energy storage power source 100, responsible for ensuring the safe, efficient, and stable operation of the battery pack. The BMS typically consists of multiple modules, including a data acquisition module, a central processing unit (MCU), an equalization module, a communication module, and a safety protection module. These modules work together to achieve comprehensive monitoring and management of the battery pack.

[0052] In this embodiment, the bottom surface of the housing 10 is recessed inward to form a second mounting cavity 121. The second mounting cavity 121 and the third housing 30 enclose a mounting area, and a plurality of battery cells 20 are installed in the mounting area enclosed by the second mounting cavity 121 and the third housing 30.

[0053] Furthermore, in this embodiment, the third housing 30 is a cover plate covering the second mounting cavity 121.

[0054] In this embodiment, multiple battery cells 20 are arranged in an upright array, that is, the length direction of the battery cells 20 is arranged in the second mounting cavity 121 in a vertical direction to ensure minimal space occupation.

[0055] In other embodiments, the multiple cells 20 may also be arranged in an array along other directions as needed.

[0056] Please see Figure 2 In some embodiments, the housing 10 includes a first housing 11 and a second housing 12, the first housing 11 and the second housing 12 are detachably connected, a second mounting cavity 121 is disposed on the second housing 12, the first housing 11 and the second housing 12 surround to form a first mounting cavity 111, and a third housing 30 is mounted on the second housing 12.

[0057] This facilitates the machining of the second mounting cavity 121, and also facilitates the electrical connection between the battery cell 20 and the electrical connector 40.

[0058] Specifically, in the embodiments of this application, the housing 10 includes a first housing 11 and a second housing 12, wherein the first housing 11 is the upper housing and the second housing 12 is the lower housing. The first housing 11 and the second housing 12 are integrally formed structures and are detachably connected by fasteners to form a complete housing 10.

[0059] In this embodiment, the bottom surface of the second housing 12 is recessed inward to form the second mounting cavity 121. In other embodiments, the top surface of the first housing 11 may also be recessed inward to form the second mounting cavity 121.

[0060] In other embodiments, the first housing 11 and the second housing 12 may also be an upper housing and a lower housing or a front housing and a rear housing, respectively. The specific choice can be made according to actual needs, and will not be elaborated on here.

[0061] A handle 50 is provided on the first housing 11, which is used for moving and transporting the energy storage power supply 100.

[0062] Furthermore, a clearance groove is provided on the first housing 11, the clearance groove is located on the top of the first housing 11, and the handle 50 is rotatably mounted on the first housing 11 and can be rotatably stored in the clearance groove.

[0063] In some embodiments, the handle 50 is made of metal. Specifically, the handle 50 can be made of aluminum alloy with a hollow interior, which is beneficial for the weight reduction of the energy storage power supply 100. In addition, the aluminum alloy handle 50 has high strength and durability, which helps to increase the reliability of the handle 50 and extend its service life.

[0064] In other embodiments, the handle 50 may also be made of other materials, which can be set according to actual needs and are not limited here.

[0065] In other embodiments, the handle 50 may also be configured as a flexible handle 50, which has good adaptability and flexibility, and better comfort and feel.

[0066] In this embodiment, a support portion is provided on the side of the second housing 12 away from the battery module, and an anti-slip structure is provided on the support portion. Optionally, the anti-slip structure can be an anti-slip silicone pad, an anti-slip rubber pad, or an anti-slip pattern provided on the support portion.

[0067] In other embodiments, a fixing groove may also be provided on the side of the second housing 12 away from the battery module, and a thicker anti-slip pad may be provided in the fixing groove. The material of the anti-slip pad may be selected according to actual needs and is not limited here.

[0068] In some embodiments, the second housing 12 and the third housing 30 form part of the outer surface of the energy storage power supply 100.

[0069] In this way, the battery cell 20 is integrated with the housing 10. While protecting the internal structure of the energy storage power supply 100, the housing 10 also serves as a traditional support, realizing the multiple uses of the housing 10.

[0070] Please see Figure 3 and Figure 4 In some embodiments, a plurality of first positioning grooves 122 are provided on the inner wall of the second mounting cavity 121, and one end of a plurality of battery cells 20 is inserted into the plurality of first positioning grooves 122. The third housing 30 fixes one end of the battery cell 20 to the first positioning groove 122.

[0071] Thus, the first positioning groove 122 is used to fix the battery cell 20 and prevent the battery cell 20 from shifting when it is electrically connected to the electrical connector 40.

[0072] Furthermore, the third housing 30 is provided with a plurality of second positioning slots 31, and the other end of the plurality of battery cells 20 is inserted into the plurality of second positioning slots 31.

[0073] Thus, the second positioning groove 31 is used to fix the battery cell 20 and prevent the battery cell 20 from shifting when it is electrically connected to the electrical connector 40.

[0074] Specifically, the first positioning groove 122 is disposed on the inner wall of the second mounting cavity 121 of the second housing 12, and the second positioning groove 31 is disposed on the third housing 30.

[0075] Furthermore, there are multiple first positioning slots 122 arranged in an array, and multiple second positioning slots 31 arranged in an array, with each second positioning slot 31 corresponding to a first positioning slot 122. In this embodiment, one second positioning slot 31 cooperates with one first positioning slot 122 to fix one battery cell 20.

[0076] Please see Figure 2In some embodiments, the energy storage power supply 100 further includes an electrical connector 40 disposed in the first mounting cavity 111, and a plurality of battery cells 20 are electrically connected to the electrical connector 40.

[0077] Thus, the electrical connector 40 is located in the first mounting cavity 111, which facilitates connection with the battery cell 20 and helps to improve the space utilization inside the energy storage power supply 100.

[0078] Specifically, electrical connector 40 is a busbar, a device with high conductivity, stability, and reliability used to concentrate or distribute current. In the field of electrical engineering, busbars are also known as busbars or bus bars, and are used to connect multiple electrical lines. Busbars are made of highly conductive materials to ensure efficient current transmission. Busbars also have good current carrying and transmission capabilities, enabling them to respond quickly to changes in the power grid and ensure the stable operation of the power grid.

[0079] The electrical connector 40 can connect the positive terminal 21 and the negative terminal 22 of at least one battery cell 20 in sequence, so that the positive terminal 21 and the negative terminal 22 connected to the two ends of the electrical connector 40 are the positive terminal and the negative terminal, respectively. In other words, the electrical connector 40 is connected in series with at least one battery cell 20, so that at least one battery cell 20 forms a high voltage output power supply, thereby ensuring that the user's power demand is met.

[0080] Specifically, cell 20 is a cylindrical cell or a square cell.

[0081] In this embodiment, the electrical connector 40 is plate-shaped, and each electrical connector 40 connects two battery cells 20, realizing series connection between the six battery cells 20. The electrical connector 40 can be made of copper, aluminum, nickel, or an alloy. After the electrical connector 40 is fixed in the correct position by the working fixture, the electrical connector 40 can be welded to the electrodes of the battery cells 20 by laser welding. It is understood that other connection methods such as twisting or pressing can also be used to achieve the electrical connection between the electrical connector 40 and the electrodes of the battery cells 20.

[0082] Furthermore, in order to cope with the slight deformation that the battery cell 20 may undergo during charging and discharging, a flexible connector can be used to connect the battery cell 20 and the electrical connector 40 to improve the reliability and stability of the connection.

[0083] Please see Figure 5 In some embodiments, a plurality of openings 123 communicating with the second mounting cavity 121 are formed on the inner wall of the first mounting cavity 111, and a plurality of battery cells 20 are electrically connected to the electrical connector 40 through the openings 123.

[0084] Thus, the opening 123 facilitates the electrical connection between the battery cell 20 and the electrical connector 40.

[0085] Specifically, in this embodiment, the openings 123 should be evenly distributed on the inner wall of the first mounting cavity 111 to ensure that the battery cell 20 can be evenly electrically connected to the electrical connector 40. At the same time, the number of openings 123 should be rationally designed according to the number and layout of the battery cells 20.

[0086] In this embodiment, by forming an opening 123 on the inner wall of the first mounting cavity 111, the battery cell 20 can be more easily electrically connected to the electrical connector 40 disposed on the surface of the second mounting cavity 121 away from the battery cell 20, without the need for complex wiring or additional connection structures. At the same time, the opening 123 can serve as a heat dissipation channel, helping the heat generated by the battery cell 20 to be better dissipated to the outside of the housing 10, thereby improving the overall heat dissipation performance of the energy storage power supply 100.

[0087] It is important to note that a sealing structure should be installed at opening 123 to prevent external impurities such as moisture and dust from entering the housing 10 and affecting the performance and safety of the energy storage power supply 100. When installing a sealing structure at opening 123, the reliability and durability of the sealing structure should be ensured.

[0088] In addition, the heat dissipation requirements of the energy storage power supply 100 should be fully considered, and the position, number and shape of the openings 123 should be designed reasonably to ensure that the energy storage power supply 100 can still operate normally in high-temperature environments.

[0089] In some embodiments, the electrical connector 40 may also be injection molded into the housing 10, with both ends of the electrical connector 40 extending from the opening 123 for connecting the electrodes of the battery cell 20. The two ends of the electrical connector 40 are connected to the electrodes of the battery cell 20 by welding.

[0090] Please see Figure 2 and Figure 6 In some embodiments, the battery cell 20 includes a positive electrode 21 and a negative electrode 22, which are located at the same end of the battery cell 20. The positive electrode 21 and the negative electrode 22 are connected to the first mounting cavity 111 through an opening 123. The electrical connector 40 connects the positive electrode 21 of the battery cell 20 and the negative electrode 22 of the adjacent battery cell 20.

[0091] Thus, by simply placing the opening 123 and the electrical connector 40 on the same inner wall of the second mounting cavity 121, the structure of the energy storage power supply 100 is simplified, and the installation and fixing of the battery cell 20 is also facilitated.

[0092] Specifically, in this embodiment, the positive electrode 21 and negative electrode 22 of the battery cell 20 are located at the same end and within the opening 123, making the connection between the battery cell 20 and the electrical connector 40 more direct and simplified, reducing additional connection components and steps. Since both the positive electrode 21 and negative electrode 22 are located within the opening 123, the battery cell 20 can be more easily aligned and connected with the electrical connector 40, improving connection efficiency and accuracy.

[0093] In some embodiments, the opening 123 includes a first opening 1231 and a second opening 1232, with the first opening 1231 and the second opening 1232 respectively corresponding to the positive electrode 21 and the negative electrode 22.

[0094] Thus, the first opening 1231 and the second opening 1232 correspond to the positive electrode 21 and the negative electrode 22 of the battery cell 20, respectively, which facilitates the connection and differentiation of the electrical connector 40.

[0095] Specifically, in the embodiments of this application, the first opening 1231 and the second opening 1232 are respectively set to the positive electrode 21 and the negative electrode 22 of the battery cell 20, which can ensure that the positive electrode 21 and the negative electrode 22 of the battery cell 20 can be accurately aligned with the corresponding opening 123 during installation, thereby improving the accuracy and reliability of the connection.

[0096] Furthermore, by separately setting the openings 123 for the positive electrode 21 and the negative electrode 22, the short circuit problem caused by accidental contact between the positive electrode 21 and the negative electrode 22 during installation or use can be effectively avoided, thus improving the safety of the energy storage power supply 100.

[0097] In this embodiment, the first opening 1231 and the second opening 1232 should be reasonably arranged on the inner wall of the second mounting cavity 121 to ensure that the positive electrode 21 and the negative electrode 22 of each cell 20 can correspond to the corresponding opening 123. The position, size and shape of the opening 123 should be customized according to the size and shape of the cell 20.

[0098] Furthermore, a certain distance should be maintained between the first opening 1231 and the second opening 1232 to prevent accidental contact between the positive electrode 21 and the negative electrode 22 of the battery cell 20 during installation or use. At the same time, the spacing of the openings 123 should also take into account the thermal expansion and contraction effects between the battery cells 20.

[0099] Please see Figure 5 In some embodiments, a partition 124 is also provided on the housing 10. The partition 124 is disposed on the surface of the second mounting cavity 121 away from the cell 20 and is located between the first opening 1231 and the second opening 1232.

[0100] Thus, the partition 124 forms a barrier between the positive electrode 21 and the negative electrode 22 of the battery cell 20, preventing the electrical connector 40 from accidentally touching the battery cell 20 and causing a short circuit.

[0101] Specifically, in this embodiment, the partition 124 is disposed between the first opening 1231 and the second opening 1232, effectively isolating the electrical connection areas of the positive electrode 21 and the negative electrode 22, preventing electrical faults caused by accidental contact or short circuit, and improving the safety performance of the energy storage power supply 100. The partition 124 separates the electrical connection areas of the positive electrode 21 and the negative electrode 22, making the wiring between the cell 20 and the electrical connector 40 clearer and more orderly, reducing the complexity of the wiring and potential interference.

[0102] On the other hand, the partition 124 also increases the structural strength of the housing 10, especially on the surface of the second mounting cavity 121 away from the cell 20, providing additional support to help resist external shocks and vibrations and extend the service life of the energy storage power supply 100.

[0103] Furthermore, the partition 124 should be made of an insulating material, such as plastic, ceramic, or a special insulating composite material, to ensure effective electrical isolation. Simultaneously, the material should have good heat resistance and corrosion resistance. The partition 124 should be large enough to separate the area between the two openings 123 while avoiding interference with the connection between the battery cell 20 and the electrical connector 40.

[0104] The partition 124 should be securely installed on the housing 10 by appropriate fixing methods (such as screws, clips, or adhesives) to prevent it from moving or falling off during use. In the embodiments of this application, the partition 124 and the housing 10 are integrally formed structures.

[0105] It is important to note that the partition 124 should avoid affecting the thermal management requirements within the energy storage power supply 100, ensuring that the partition 124 does not obstruct normal heat dissipation while also preventing localized overheating. Furthermore, the installation position and dimensions of the partition 124 should be strictly controlled to ensure that it functions correctly and effectively.

[0106] Please see Figure 3 and Figure 4 In some embodiments, the housing 10 includes a plurality of first connecting posts 125 located within the second mounting cavity 121, and the third housing 30 includes a plurality of second connecting posts 32. When the third housing 30 is mounted on the housing 10, the first connecting posts 125 are connected to the second connecting posts 32.

[0107] Thus, the first connecting post 125 and the second connecting post 32 are used to connect the housing 10 and the third housing 30. The first connecting post 125 is beneficial to improving the structural strength of the housing 10, and the second connecting post 32 is beneficial to improving the structural strength of the third housing 30.

[0108] Specifically, in this embodiment, the housing 10 is provided with a first connecting post 125, and there are multiple first connecting posts 125, which are spaced apart on the housing 10.

[0109] The third housing 30 is provided with a second connecting post 32 at the position corresponding to the first connecting post 125. There are multiple second connecting posts 32, and the number of second connecting posts 32 is the same as that of the first connecting posts 125. The second connecting posts 32 and the first connecting posts 125 are arranged in a one-to-one correspondence.

[0110] In some embodiments, the first connecting post 125 and the second connecting post 32 are relatively long. To improve their structural strength, a first reinforcing rib may be provided on the side of the first connecting post 125. The first reinforcing rib is triangular or trapezoidal, with one end connected to the first connecting post 125 and the other end connected to the inner wall of the second mounting cavity 121. Similarly, a second reinforcing rib is also provided on the second connecting post 32. The second reinforcing rib is triangular or trapezoidal, with one end connected to the second connecting post 32 and the other end connected to the third housing 30.

[0111] Furthermore, each first connecting post 125 may be connected to multiple first reinforcing ribs. Similarly, each second connecting post 32 may be connected to multiple second reinforcing ribs. In some embodiments, each first connecting post 125 is connected to at least four first reinforcing ribs, and the four first reinforcing ribs are evenly arranged on the side wall of the first connecting post 125. Similarly, each second connecting post 32 is connected to at least four second reinforcing ribs, and the four second reinforcing ribs are evenly arranged on the side wall of the second connecting post 32.

[0112] Furthermore, the first connecting post 125 and the second connecting post 32 can be detachably connected via fasteners to connect the housing 10 and the third housing 30. Bolt connection is one of the most common methods for fastening the third housing 30 to the housing 10. Through the cooperation of bolts and nuts, the third housing 30 and the housing 10 are tightly connected together. Bolt connection has advantages such as simple structure, convenient disassembly, and strong load-bearing capacity.

[0113] Furthermore, depending on the application requirements, different types of bolts can be selected, such as ordinary bolts and high-strength bolts. High-strength bolts have better performance when bearing larger loads.

[0114] It is important to note that the tightening torque of bolted connections is one of the key parameters and needs to be calculated and set based on the specific materials and structure. Appropriate tightening torque ensures the stability and safety of the connection.

[0115] In some embodiments, the third housing 30 and housing 10 may also be connected by other connectors or fasteners. Connectors are components that connect the third housing 30 and housing 10 together, such as bolts, nuts, and washers. The selection and installation of connectors have a significant impact on the stability and safety of the connection. The material of the connectors should have good mechanical properties and chemical stability to adapt to different working environments and load requirements. The size of the connectors should be calculated and determined based on the dimensions of the third housing 30 and housing 10 and the load requirements.

[0116] Fasteners are components used to secure connections, such as wrenches and screwdrivers. The selection and use of fasteners have a significant impact on the tightness and stability of the connection. Appropriate fasteners should be selected based on the type and size of the connectors. When using fasteners, the tightening force needs to be controlled to ensure the stability and safety of the connection. Excessive tightening force may damage or deform the connectors, while insufficient tightening force may result in a weak connection.

[0117] In some embodiments, the third housing 30 and the housing 10 can also be connected together by welding. Welded connections have advantages such as high connection strength and good sealing performance, but compared with bolted connections, disassembly and maintenance are more difficult.

[0118] Furthermore, depending on the materials and application requirements, different welding types can be selected, such as spot welding and seam welding.

[0119] It is important to note that welding quality directly affects the stability and safety of the connection. Therefore, welding parameters and quality must be strictly controlled during the welding process to ensure that the welding quality meets relevant standards and requirements.

[0120] Furthermore, the first connecting post 125 and the housing 10 are integrally formed as a single structure, and similarly, the second connecting post 32 and the third housing 30 are also integrally formed as a single structure.

[0121] Please see Figure 2 In some embodiments, the housing 10 is provided with a ventilation hole 131, which allows the first mounting cavity 111 to communicate with the outside.

[0122] Thus, the ventilation hole 131 can be used to dissipate heat for the energy storage power supply 100, preventing the battery cell 20 of the energy storage power supply 100 from thermal runaway due to excessive internal temperature.

[0123] Specifically, in this embodiment, when the energy storage power supply 100 is working, a large amount of heat is generated inside, especially in the battery cell 20. The heat generated by the battery cell 20 is transferred to the first mounting cavity 111 through the housing 10, causing the temperature inside the first mounting cavity 111 to gradually rise, which affects the normal use of the energy storage power supply 100. The ventilation hole 131 connects the first mounting cavity 111 to the outside, which allows the heat generated inside to dissipate to the environment in a timely manner, avoiding the accumulation of a large amount of heat inside the energy storage power supply 100 and affecting the working state of the energy storage power supply 100.

[0124] In this embodiment, the housing 10 also includes a decorative panel 13, and ventilation holes 131 are formed on the decorative panel 13.
