[0041] The energy storage power supply 100 provided in the embodiment of the present application utilizes the pull rod housing 40 to replace the cover plate to cover the first through hole, thereby protecting the battery cell 21 and preventing the battery cell 21 from being connected incorrectly, while also saving components, which is beneficial to reducing the assembly process and reducing costs.

[0042] Specifically, the energy storage power supply 100 is a device that can store electrical energy and release it when needed, and its main function is to provide a stable and reliable power supply. When the system needs to store electrical energy, the controller will charge the battery pack, and the battery pack will convert the electrical energy into chemical energy for storage; when the system needs to use electrical energy, the controller will first convert the DC electrical energy stored in the battery pack into AC electrical energy, and then output it.

[0043] In the embodiment of the present application, a receiving cavity is formed in the housing 10, and the battery module 20 is disposed in the receiving cavity.

[0044] The battery module 20 includes a plurality of battery cells 21 , which are arranged in an upright array, that is, the length direction of the battery cells 21 is arranged along the vertical direction to ensure that the space occupied is minimized.

[0045] In other embodiments, the plurality of battery cells 21 may also be arranged in arrays along other directions according to actual needs.

[0046] In some embodiments, the battery cell 21 has two electrodes, which are respectively disposed on two opposite sides of the battery cell 21 . When arranged in an array, the electrodes are respectively disposed on two sides of the battery pack to facilitate connection between the battery cells 21 .

[0047] In some embodiments, the battery cell 21 has two electrodes, and the two electrodes are disposed on the same side of the battery cell 21 . When arranged in an array, the electrodes should be concentrated on the same side of the battery pack to facilitate connection between the battery cells 21 .

[0048] The first electrical connector 30 is a busbar, which is a device with high conductivity, high stability and reliability, used to concentrate or disperse current. In the field of electricity, the busbar is also called a busbar, busbar, etc., which is used to connect multiple electrical lines. The busbar is made of highly conductive materials to ensure the high efficiency of current transmission. The busbar also has good current carrying and transmission capabilities, can quickly respond to changes in the power grid, and ensure the stable operation of the power grid.

[0049] The first electrical connector 30 can connect the positive poles and the negative poles of at least one battery cell 21 alternately in sequence, so that the positive pole and the negative pole connected to the two ends of the first electrical connector 30 are the positive wiring port and the negative wiring port respectively. That is, the first electrical connector 30 is connected in series with at least one battery cell 21, so that at least one battery cell 21 forms a high-voltage output power supply, thereby ensuring that the user's power demand is met.

[0050] In this embodiment, the first electrical connector 30 is in the shape of a plate, each of which connects six battery cells 21 to realize the series connection between the six battery cells 21. The first electrical connector 30 can be made of copper, aluminum, nickel or alloy material. After the first electrical connector 30 is fixed to the correct position by a working fixture, the first electrical connector 30 and the electrode of the battery cell 21 can be welded together by laser welding. It can be understood that the electrical connection between the first electrical connector 30 and the electrode of the battery cell 21 can also be achieved by other connection methods such as twisting or pressing.

[0051] See also Figure 2 In some embodiments, the housing 10 is the rear housing of the energy storage power supply 100, and the pull rod housing 40 includes a rear decorative housing 41 and a pull rod 42 formed on the top of the rear decorative housing 41, and the rear decorative housing 41 covers the electrical connector.

[0052] In this way, the pull rod housing 40 is arranged on the rear housing, so as to facilitate the transportation of the energy storage power supply 100 .

[0053] Specifically, the pull rod 42 includes a handle and a connecting rod. The number of the connecting rods is usually two, and the two connecting rods are respectively installed at both ends of the handle.

[0054] In the embodiment of the present application, the handle is made of metal, specifically, aluminum alloy, with a hollow interior, which is beneficial to lightweighting the energy storage power supply 100. The strength and durability of the aluminum alloy handle are high, which is beneficial to increasing the reliability of the handle and extending its service life.

[0055] Furthermore, a mounting groove is provided on the rear shell body, and the pull rod shell body 40 is arranged in the mounting groove, and the handle can pass through the mounting groove and be exposed on the outside of the shell body 10 .

[0056] In other embodiments, the handle may also be made of other materials, which may be specifically configured according to actual needs and is not limited here.

[0057] In other embodiments, the handle may also be configured as a flexible handle, which has good adaptability and flexibility, and has better comfort and touch.

[0058] In the embodiment of the present application, the connecting rod is slidably disposed in the pull rod housing 40 .

[0059] In some embodiments, a slide groove is disposed in the pull rod housing 40, and the connecting rod is slidably disposed in the slide groove.

[0060] Furthermore, in some embodiments, an elastic locking pin is provided on the connecting rod, and a locking hole is provided on the side wall of the slide slot to cooperate with the elastic locking pin. When the connecting rod is pulled out to the farthest point of the handle from the rod housing 40 or retracted to the closest point of the handle from the rod housing 40, the elastic locking pin is inserted into the locking hole to lock the handle.

[0061] Furthermore, in some embodiments, a control button is provided on the handle, and the control button is used to control the recovery of the elastic locking pin, so that the elastic locking pin is pulled out of the locking hole to achieve unlocking.

[0062] In the embodiment of the present application, the connecting rod is made of a tube made of a metal material. In the present embodiment, the connecting rod is a square tube made of stainless steel.

[0063] Furthermore, in some embodiments, the cross-sectional shape of the slide groove that cooperates with the connecting rod is also square.

[0064] In some embodiments, the battery module 20 includes a bracket 22 , and one end of the plurality of battery cells 21 away from the housing 10 is inserted into the bracket 22 .

[0065] In this way, the bracket 22 is used to assist in fixing the battery cell 21 , which is helpful to simplify the assembly of the battery cell 21 .

[0066] Specifically, the plurality of battery cells 21 of the battery module 20 are arrayed and fixed inside the bracket 22 , so that the disassembly, assembly and maintenance of the battery module 20 can be facilitated.

[0067] In some embodiments, the housing 10 is fixedly connected to the bracket 22 .

[0068] In this way, the housing 10 and the bracket 22 are tightly connected, which facilitates maintenance and replacement of the housing 10 and the bracket 22 .

[0069] Specifically, the fastening connection between the housing 10 and the bracket 22 is an important step in ensuring the stability and safety of the internal structure of the energy storage power supply 100. In the embodiment of the present application, the connection type is bolted connection.

[0070] Bolt connection is one of the most common ways to fasten the housing 10 to the bracket 22. The housing 10 and the bracket 22 are tightly connected together by the cooperation of bolts and nuts. Bolt connection has the advantages of simple structure, easy disassembly, and strong bearing capacity.

[0071] Furthermore, according to the application requirements, different types of bolts can be selected, such as ordinary bolts, high-strength bolts, etc. High-strength bolts have better performance when subjected to larger loads.

[0072] It should be noted that the tightening torque of the bolt connection is one of the key parameters and needs to be calculated and set according to the specific material and structure. The appropriate tightening torque can ensure the stability and safety of the connection.

[0073] In some embodiments, the housing 10 and the bracket 22 may be connected by other connectors or fasteners. The connector is a component that connects the housing 10 and the bracket 22 together, such as a bolt, a nut, a washer, etc. The selection and installation of the connector has an important impact on the stability and safety of the connection. The connector material should have good mechanical properties and chemical stability to adapt to different working environments and load requirements. The size of the connector should be calculated and determined based on the size and load requirements of the housing 10 and the bracket 22.

[0074] Fasteners are components used to fix connectors, such as wrenches and screwdrivers. The selection and use of fasteners have an important impact on the tightness and stability of the connection. Choose the right fastener based on the type and size of the connector. When using fasteners, you need to control the size of the fastening force to ensure the stability and safety of the connection. Excessive fastening force may cause damage or deformation of the connector, while too little fastening force may result in a loose connection.

[0075] In some embodiments, the housing 10 and the bracket 22 may be connected together by welding. Welding connection has the advantages of high connection strength and good sealing, but is more difficult to disassemble and repair than bolt connection.

[0076] Furthermore, different welding types can be selected, such as spot welding, seam welding, etc., depending on the material and application requirements.

[0077] It should be noted that welding quality directly affects the stability and safety of the connection. Therefore, welding parameters and quality need to be strictly controlled during the welding process to ensure that the welding quality meets relevant standards and requirements.

[0078] See also Figure 3 In some embodiments, the shell 10 includes a plurality of first reinforcement columns 12 , the bracket 22 includes a plurality of second reinforcement columns 221 , and when the shell 10 is connected to the bracket 22 , the first reinforcement columns 12 are connected to the second reinforcement columns 221 .

[0079] In this way, the first reinforcement column 12 and the second reinforcement column 221 are used to connect the shell 10 and the bracket 22 , and the first reinforcement column 12 is helpful to improve the structural strength of the shell 10 , and the second reinforcement column 221 is helpful to improve the structural strength of the bracket 22 .

[0080] Specifically, in the embodiment of the present application, the first reinforcement column 12 is disposed on the first inner wall of the rear housing 10, and the plurality of first reinforcement columns 12 are arranged in a multi-row and multi-column array. Similarly, the second reinforcement column 221 is disposed on the second inner wall of the bracket 22, and the plurality of second reinforcement columns 221 are arranged in a multi-row and multi-column array.

[0081] Furthermore, the first reinforcement column 12 and the bottom shell are an integral structure formed by integral processing, and the second reinforcement column 221 and the top shell are an integral structure formed by integral processing.

[0082] In some embodiments, since the first reinforcement column 12 and the second reinforcement column 221 are relatively long, in order to improve their structural strength, a first reinforcement rib is further provided on the bottom shell, the first reinforcement rib is triangular or trapezoidal, one end of the first reinforcement rib is connected to the first inner wall, and the other end of the first reinforcement rib is connected to the first reinforcement column 12. Similarly, a second reinforcement rib is further provided on the top shell, the second reinforcement rib is triangular or trapezoidal, one end of the second reinforcement rib is connected to the second inner wall, and the other end of the second reinforcement rib is connected to the second reinforcement column 221.

[0083] Furthermore, each first reinforcement column 12 is connected to multiple first reinforcement ribs, and similarly, each second reinforcement column 221 is connected to multiple second reinforcement ribs. In the embodiment of the present application, each first reinforcement column 12 is connected to at least three first reinforcement ribs, and similarly, each second reinforcement column 221 is connected to at least three second reinforcement ribs.

[0084] In some embodiments, the bracket 22 is formed with second positioning holes 222 corresponding to the plurality of first positioning holes 11 .

[0085] In this way, the second positioning hole 222 is used to fix the battery cell 21 together with the first positioning hole 11 , which is conducive to making the battery cell 21 more stably fixed. At the same time, the battery cell 21 can be pre-assembled on the bracket 22 to facilitate the assembly of the battery cell 21 .

[0086] Specifically, the first positioning hole 11 and the second positioning hole 222 are used to fix the battery module 20 .

[0087] Specifically, the first positioning hole 11 is disposed on the first inner wall of the rear housing, and the second positioning hole 222 is disposed on the second inner wall of the bracket 22 .

[0088] Further, the number of the first positioning holes 11 is multiple, and the multiple first positioning holes 11 are arranged in an array, the number of the second positioning holes 222 is multiple, and the multiple second positioning holes 222 are arranged in an array, and the second positioning holes 222 are arranged in a one-to-one correspondence with the first positioning holes 11. In this embodiment, the battery module 20 includes a plurality of battery cells 21 arranged in an array, and one second positioning hole 222 cooperates with one first positioning hole 11 to fix one battery cell 21 of the battery module 20.

[0089] In this embodiment, the plurality of first reinforcement columns 12 are disposed at intervals between the plurality of first positioning holes 11 , and the plurality of second reinforcement columns 221 are disposed at intervals between the plurality of second positioning holes 222 .

[0090] In some embodiments, the first positioning holes 11 may be defined between two adjacent rows and two columns of first reinforcing columns 12 , and the array arrangement of a plurality of first reinforcing columns 12 enables the first positioning holes 11 to be arranged at intervals.

[0091] Similarly, second positioning holes 222 are defined between two adjacent rows and two columns of the second reinforcing columns 221 , and the array arrangement of the plurality of second reinforcing columns 221 enables the second positioning holes 222 to be placed at intervals.

[0092] It can be understood that by forming the first positioning holes 11 and the second positioning holes 222 arranged at intervals by the plurality of first reinforcing columns 12 and the second reinforcing columns 221, the plurality of battery cells 21 can be placed at intervals, and problems such as thermal expansion caused by direct contact of the plurality of battery cells 21 can be reduced, as well as the situation where the energy storage power supply 100 causes the plurality of battery cells 21 to be squeezed and deformed against each other due to collision, thereby reducing safety risks.

[0093] In some embodiments, cylindrical first positioning holes 11 and second positioning holes 222 may be defined between two adjacent rows and two columns of first reinforcing columns 12 and two adjacent rows and two columns of second reinforcing columns 221 to ensure that the cylindrical battery cell 21 is stably placed, thereby improving the stability of the cylindrical battery cell 21.

[0094] In detail, the outer peripheral walls of each first reinforcement column 12 and the second reinforcement column 221 form an arc surface to enclose a cylindrical first positioning hole 11 and a second positioning hole 222, so that the cylindrical hole matches the outer peripheral wall of the battery cell 21, thereby ensuring the connection effect between the battery cell 21 and the positioning part and reducing shaking.

[0095] In other embodiments, the first positioning hole 11 and the second positioning hole 222 may also be in other shapes, such as a rectangle, etc., to ensure that the battery cells 21 of different shapes are stably placed, and no specific limitation is made here.

[0096] See also Figure 2In some embodiments, the energy storage power supply 100 further includes a second electrical connector 50 , which is disposed on a side of the bracket 22 opposite to the battery cells 21 and is electrically connected to the plurality of battery cells 21 .

[0097] In this way, the second electrical connector 50 can balance the current and overvoltage protection, reduce the damage and replacement frequency of the battery cells 21 , and thus reduce the maintenance cost of the battery module 20 .

[0098] Specifically, the second electrical connector 50 is a busbar, which is a device with high conductivity, high stability and reliability, used to concentrate or disperse current. In the field of electricity, the busbar is also called a busbar, busbar, etc., which is used to connect multiple electrical lines. The busbar is made of highly conductive materials to ensure the high efficiency of current transmission. The busbar also has good current carrying and transmission capabilities, can quickly respond to changes in the power grid, and ensure the stable operation of the power grid.

[0099] The second electrical connector 50 can connect the positive poles and the negative poles of at least one battery cell 21 alternately in sequence, so that the positive pole and the negative pole connected to the two ends of the second electrical connector 50 are the positive wiring port and the negative wiring port respectively. That is, the second electrical connector 50 is connected in series with at least one battery cell 21, so that at least one battery cell 21 forms a high-voltage output power supply, thereby ensuring that the user's power demand is met.

[0100] In this embodiment, the second electrical connector 50 is plate-shaped, each second electrical connector 50 connects six battery cells 21 to achieve series connection between the six battery cells 21, and the second electrical connector 50 can be made of copper, aluminum, nickel or alloy material. After the second electrical connector 50 is fixed to the correct position by a working fixture, the second electrical connector 50 and the electrode of the battery cell 21 can be welded together by laser welding. It can be understood that the electrical connection between the second electrical connector 50 and the electrode of the battery cell 21 can also be achieved by other connection methods such as twisting or pressing.

[0101] In some embodiments, the energy storage power supply 100 further includes an insulating layer 60 , which is disposed between the first electrical connector 30 and the pull rod housing 40 .

[0102] In this way, the insulating layer 60 can effectively isolate the first electrical connector 30 from the rod housing 40 , thereby preventing the metal component on the rod housing 40 from accidentally contacting the first electrical connector 30 and causing leakage or short circuit.

[0103] Specifically, in the embodiment of the present application, the main function of the insulating layer 60 is to isolate the electrical connector and the pull rod housing 40 to prevent current leakage and short circuit. The isolation function of the insulating layer 60 can ensure the safety of the power supply during use.

[0104] The insulating layer 60 can also provide a certain mechanical protection for the first electrical connector 30 and the pull rod housing 40. It can withstand a certain mechanical pressure and impact force, and protect the internal circuit and structure from damage.

[0105] The material of the insulating layer 60 generally has excellent heat resistance and corrosion resistance and can adapt to various complex use environments, which can ensure that the power supply can work normally in various harsh environments and improve the reliability and stability of the power supply.

[0106] The material of the insulating layer 60 needs to have excellent insulation performance and mechanical strength, as well as good heat resistance and corrosion resistance. Common materials of the insulating layer 60 include rubber, plastic, ceramic, etc. These materials can effectively isolate the electrical connector and the pull rod housing 40 to prevent current leakage and short circuit.

[0107] The design of the insulating layer 60 needs to take into account the structure and use environment of the power supply. In the embodiment of the present application, the insulating layer 60 should be tightly fitted between the electrical connector and the pull rod housing 40 without leaving any gap. At the same time, the thickness of the insulating layer 60 also needs to be reasonably designed according to the voltage and current level of the power supply to ensure that it can withstand sufficient voltage and current shocks.

[0108] In some embodiments, the energy storage power supply 100 further includes a collection board 70 , and the collection board 70 is connected to the plurality of first electrical connectors 30 .

[0109] Thus, providing the acquisition board 70 is beneficial to the real-time monitoring and data acquisition of battery parameters.

[0110] Specifically, the acquisition board 70 is also called a battery information collector or a battery pack acquisition board 70 (BIC), which is an important component of the battery management system (BMS). The acquisition board 70 connects to the battery cell 21 in the battery module 20, collects the voltage, temperature and other parameters of the battery cell 21 in real time, and transmits these parameters to the BMS. Based on the collected data, the BMS controls and manages the charging, discharging, thermal management and other aspects of the battery pack to ensure the safe and efficient operation of the battery pack.

[0111] The acquisition board 70 is mainly responsible for real-time monitoring and acquisition of status information of each battery cell 21 in the battery module 20, such as voltage, temperature, etc. By collecting this information, the BMS can accurately understand the working status of the battery module 20 and perform corresponding management and control. The acquisition board 70 can accurately collect parameters such as voltage and temperature of each battery cell 21 in the battery module 20 through high-precision sensors and circuit design. The acquisition board 70 can monitor the working status of the battery module 20 in real time to ensure that the BMS can understand the operation of the battery module 20 in a timely manner. In addition to the basic voltage and temperature parameters, the acquisition board 70 can also collect other parameters such as current and internal resistance to provide the BMS with more comprehensive battery module 20 status information. The acquisition board 70 usually uses high-performance and high-reliability electronic components and materials to ensure that it can still work stably in harsh environments.

[0112] The energy storage power supply 100 can collect the status information of each battery cell 21 through the acquisition board 70. The status information of the battery cell 21 may include information such as the voltage, current and temperature of each battery cell 21. The acquisition board 70 may include a first acquisition board 70 and a second acquisition board 70. The first acquisition board 70 is connected to the first electrical connector 30. The second acquisition board 70 is connected to the second electrical connector 50. After the first electrical connector 30 and the second electrical connector 50 are welded, the first acquisition board 70 can be fixed to the corresponding position on the first electrical connector 30 by screws, and the second acquisition board 70 can be fixed to the corresponding position on the second electrical connector 50. After the acquisition board 70 is fixed, the nickel strip of the first acquisition board 70 and the first electrical connector 30 can be connected by an electrical connection method such as laser welding, so as to realize the electrical connection between the first acquisition board 70 and the first electrical connector 30. At the same time, the second acquisition board 70 and the second electrical connector 50 can also be connected in the same way.

[0113] See also Figure 4 In some embodiments, the energy storage power supply 100 further includes a cooling fan 80 , which is installed on a side of the battery module 20 away from the pull rod housing 40 .

[0114] In this way, the cooling fan 80 is used to assist the heat dissipation of the battery module 20 , which is beneficial to prolonging the service life of the battery module 20 .

[0115] Specifically, as a highly integrated and high-power device, the heat dissipation performance of the energy storage power supply 100 is crucial to its stability and safety. In the design of the energy storage power supply 100, the heat dissipation fan 80 is an indispensable component, especially in the battery module 20 part.

[0116] Since the battery module 20 generates heat during operation, if the heat cannot be dissipated in a timely and effective manner, the temperature of the battery module 20 may rise, thereby affecting the performance and life of the battery, and may even cause a safety accident. Therefore, in the embodiment of the present application, the main function of the cooling fan 80 is to generate wind flow to take away the heat generated by the battery module 20, reduce the temperature of the battery module 20, and ensure the stable operation of the energy storage power supply 100.

[0117] Furthermore, the cooling fan 80 is spaced apart from the battery module 20 , and a radiator is also installed on the battery module 20 , between the cooling fan 80 and the battery module 20 .

[0118] Furthermore, the cooling fan 80 is spaced apart from the radiator. Maintaining an appropriate distance between the cooling fan 80 and the radiator can ensure that the airflow generated by the fan can fully and evenly blow across the surface of the radiator, thereby more effectively removing the heat from the radiator.
