[0050] In some embodiments, the battery cell 21 has two electrodes, which are arranged on the same side of the battery cell 21, and when arranged, the electrodes should be concentrated on the same side of the battery pack, so as to facilitate the connection between the battery cells 21.

[0051] The first electrical connecting member 30 is a busbar, which is a kind of equipment with high conductivity, high stability and reliability, used for concentrating or distributing current. In the electrical field, the busbar is also called bus, busbar, etc., used for connecting multiple electrical lines. The busbar is made of high-conductivity material to ensure efficient current transmission. The busbar also has good current carrying and transmission capacity, can quickly respond to power grid changes, and ensure the stable operation of the power grid.

[0052] The first electrical connecting member 30 can connect the positive poles and the negative poles of at least one battery cell 21 alternately, so that the positive poles and the negative poles connected to the two ends of the first electrical connecting member 30 are positive connection ports and negative connection ports, respectively, i.e., the first electrical connecting member 30 is connected in series with at least one battery cell 21, so that at least one battery cell 21 forms a large-voltage output power supply, thereby ensuring that the user's power demand is met.

[0053] In this embodiment, the first electrical connecting member 30 is in the form of a plate, each first electrical connecting member 30 connects six battery cells 21 to realize the series connection between the six battery cells 21, and the first electrical connecting member 30 can be made of copper, aluminum, nickel or alloy material.

[0055] In this way, the pull rod shell 40 is arranged on the rear shell, facilitating the carrying of the energy storage power supply 100.

[0056] In the embodiments of the present application, the pull rod shell 40 can be arranged on the side, bottom or top of the energy storage power supply 100, and correspondingly, the pull rod 42 can be arranged on the side, bottom or top of the energy storage power supply 100. The specific arrangement can be made according to the actual situation, which is not limited herein.

[0057] Referring to FIG. 3, in some embodiments, the energy storage power supply 100 further comprises a roller 91 installed on the bottom of the first shell 41.

When moving the energy storage power supply 100, the pull rod 42 is pulled to make the energy storage power supply 100 tilt towards one side of the roller 91, and the supporting part is lifted. By cooperating the pull rod 42 with the roller 91, the energy storage power supply 100 is pulled to move, thereby reducing the burden of carrying. When placing the energy storage power supply 100, the energy storage power supply 100 is placed flat, so that the supporting part and the roller 91 stably support the energy storage power supply 100, and the movement of the energy storage power supply 100 is limited by the supporting part. Alternatively, in some embodiments, the energy storage power supply 100 further comprises a roller shell 90, which can be fixed to the bottom of the energy storage power supply. The roller shell 90 comprises a second shell 92 and a roller 91 installed on the second shell. In this embodiment, the roller 91 can be provided as four, and two rollers 91 arranged on the same side of the pull rod 42 can be provided as large rollers, and the other two rollers 91 can be provided as small rollers. The small rollers are provided with brake pads, i.e. the small rollers are brake wheels, which are convenient for locking the energy storage power supply 100 to prevent the energy storage power supply 100 from sliding randomly.

[0058] Specifically, the pull rod 42 comprises a handle and a connecting rod, and the number of connecting rods is usually two, and the two connecting rods are respectively installed at both ends of the handle.

[0059] In the embodiments of the present application, the handle is made of metal material, and specifically, the handle can be made of aluminum alloy material. The inside of the handle is hollow processed, which is beneficial to the lightweight of the energy storage power supply 100. In addition, the strength and durability of the aluminum alloy handle are relatively high, which is beneficial to increase the reliability of the handle and prolong the service life of the handle.

[0060] Further, the rear shell is provided with a mounting groove, and the pull rod shell 40 is arranged in the mounting groove. The handle can be exposed outside the shell 10 from the mounting groove.

[0061] In other embodiments, the handle can also be made of other materials, and the specific arrangement can be made according to the actual needs, which is not limited herein.

[0062] In other embodiments, the handle can also be provided as a flexible handle. The flexible handle has good adaptability and flexibility, and has better comfort and touch.

[0063] In the embodiments of the present application, the connecting rod is slidingly arranged in the pull rod housing 40.

[0064] In some embodiments, a sliding groove is arranged in the pull rod housing 40, and the connecting rod is slidingly arranged in the sliding groove.

[0065] Further, in some embodiments, the connecting rod is provided with an elastic locking pin, and the side wall of the sliding groove is provided with a locking hole matched with the elastic locking pin. When the connecting rod is pulled out to the farthest position from the pull rod housing 40 or is retracted to the closest position from the pull rod housing 40, the elastic locking pin is inserted into the locking hole to lock the handle.

[0066] Further, in some embodiments, the handle is provided with a control button for controlling the retraction of the elastic locking pin, so that the elastic locking pin is pulled out of the locking hole to achieve unlocking.

[0067] In the embodiments of the present application, the connecting rod is a pipe made of metal material. In the embodiments, the connecting rod is a square pipe made of stainless steel.

[0068] Further, please continue to refer to FIG. 3. In some embodiments, the energy storage power supply 100 further comprises a handle assembly 10a arranged on the top of the energy storage power supply. When the energy storage power supply 100 cannot be moved by pulling the pull rod 42, the user can lift and carry the energy storage power supply 100 by holding the handle assembly 10a.

[0069] Further, please continue to refer to FIG. 3. In some embodiments, the housing 10 comprises a left decorative cover 13, a right decorative cover 14, a front decorative cover 15, a top cover 16 and a bottom cover 17. The left decorative cover 13, the right decorative cover 14, the front decorative cover 15, the pull rod housing 40, the top cover 16 and the bottom cover 17 are connected to form a containing cavity in which the battery module 20 is arranged.

[0070] Further, in some embodiments, the sliding groove matched with the connecting rod is also square in cross-sectional shape.

[0071] In some embodiments, the battery module 20 comprises a support 22, and the plurality of battery cells 21 are inserted into the support 22 away from one end of the housing 10.

[0072] In this way, the support 22 is used to assist in fixing the battery cells 21, which is conducive to simplifying the assembly of the battery cells 21.

[0073] Specifically, the plurality of battery cells 21 of the battery module 20 are arranged in an array inside the support 22 and are fixed, so that the disassembly and maintenance of the battery module 20 can be facilitated.

[0074] In some embodiments, the housing 10 is tightly connected with the support 22.

[0075] In this way, the shell 10 and the bracket 22 are fastened and connected, which facilitates the maintenance and replacement of the shell 10 and the bracket 22.

[0076] Specifically, the fastening and connection of the shell 10 and the bracket 22 is an important link to ensure the stability and safety of the internal structure of the energy storage power supply 100. In the embodiments of the present application, the connection type is selected to be bolted connection.

[0077] Bolted connection is one of the most common ways of fastening and connecting the shell 10 and the bracket 22. The shell 10 and the bracket 22 are tightly connected together through the cooperation of bolts and nuts. Bolted connection has the advantages of simple structure, easy disassembly, strong carrying capacity, etc.

[0078] Further, 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 bearing larger loads.

[0079] It should be noted that the fastening torque of bolted connection is one of the key parameters, which needs to be calculated and set according to the specific materials and structures. The appropriate fastening torque can ensure the stability and safety of the connection.

[0080] In some embodiments, the shell 10 and the bracket 22 can also be connected by other connectors or fasteners. Among them, the connector is a component that connects the shell 10 and the bracket 22 together, such as bolts, nuts, washers, etc. The selection and installation of the connector have an important influence 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 according to the size and load requirements of the shell 10 and the bracket 22.

[0081] The fastener is a component used to fix the connector, such as a wrench, screwdriver, etc. The selection and use of the fastener have an important influence on the fastening degree and stability of the connection. According to the type and size of the connector, select the appropriate fastener. When using the fastener, the size of the fastening force needs to be controlled to ensure the stability and safety of the connection. Excessive fastening force may cause damage or deformation of the connector, and insufficient fastening force may cause the connection to be not firm.

[0082] In some embodiments, the shell 10 and the bracket 22 can also be connected together by welding. Welded connection has the advantages of high connection strength and good sealing, but compared with bolted connection, it is more difficult to disassemble and maintain.

[0083] Further, according to the material and application requirements, different welding types can be selected, such as spot welding, seam welding, etc.

[0084] It should be noted that the welding quality directly affects the stability and safety of the connection. Therefore, the welding parameters and quality need to be strictly controlled during welding to ensure that the welding quality meets the relevant standards and requirements.

[0085] Referring to FIG. 4, in some embodiments, the shell 10 includes a plurality of first connecting columns 12, the support 22 includes a plurality of second connecting columns 221, and the first connecting columns 12 are connected with the second connecting columns 221 when the shell 10 is connected with the support 22.

[0086] In this way, the first connecting columns 12 and the second connecting columns 221 are used for connecting the shell 10 and the support 22, and the first connecting columns 12 are arranged to improve the structural strength of the shell 10, and the second connecting columns 221 are arranged to improve the structural strength of the support 22.

[0087] Specifically, in the embodiments of the present application, the first connecting columns 12 are arranged on the first inner wall of the rear shell 10, and the plurality of first connecting columns 12 are arranged in a multi-row and multi-column array. Similarly, the second connecting columns 221 are arranged on the second inner wall of the support 22, and the plurality of second connecting columns 221 are arranged in a multi-row and multi-column array.

[0088] Further, the first connecting columns 12 are integrally formed with the bottom shell, and the second connecting columns 221 are integrally formed with the top shell.

[0089] In some embodiments, since the first connecting columns 12 and the second connecting columns 221 are relatively long, in order to improve their structural strength, the bottom shell is further provided with first reinforcing ribs, the first reinforcing ribs are triangular or trapezoidal, one end of the first reinforcing ribs is connected with the first inner wall, and the other end of the first reinforcing ribs is connected with the first connecting columns 12. Similarly, the top shell is further provided with second reinforcing ribs, the second reinforcing ribs are triangular or trapezoidal, one end of the second reinforcing ribs is connected with the second inner wall, and the other end of the second reinforcing ribs is connected with the second connecting columns 221.

[0090] Further, each first connecting column 12 is connected with a plurality of first reinforcing ribs, and similarly, each second connecting column 221 is connected with a plurality of second reinforcing ribs. In the embodiments of the present application, each first connecting column 12 is connected with at least three first reinforcing ribs, and similarly, each second connecting column 221 is connected with at least three second reinforcing ribs.

[0091] In some embodiments, the support 22 is formed with a plurality of second positioning holes 222 corresponding to the plurality of first positioning holes 11 respectively.

[0092] In this way, the second positioning holes 222 are used to fix the battery cells 21 with the first positioning holes 11, which is conducive to fixing the battery cells 21 more stably, and at the same time, the battery cells 21 can be pre-assembled on the support 22, which is convenient for assembling the battery cells 21.

[0093] Specifically, the first positioning hole 11 and the second positioning hole 222 are used to fix the battery module 20.

[0094] Specifically, the first positioning hole 11 is arranged on the first inner wall of the rear shell, and the second positioning hole 222 is arranged on the second inner wall of the bracket 22.

[0095] Further, the number of the first positioning hole 11 is multiple, and the multiple first positioning holes 11 are arranged in an array, the number of the second positioning hole 222 is multiple, and the multiple second positioning holes 222 are arranged in an array, and the second positioning hole 222 is arranged in one-to-one correspondence with the first positioning hole 11. In this embodiment, the battery module 20 includes multiple arrayed battery cells 21, and one second positioning hole 222 cooperates with one first positioning hole 11 to fix one battery cell 21 of the battery module 20.

[0096] In this embodiment, multiple first connecting columns 12 are arranged at intervals of multiple first positioning holes 11, and multiple second connecting columns 221 are arranged at intervals of multiple second positioning holes 222.

[0097] In some embodiments, the first positioning hole 11 can also be defined between the two rows and two columns of adjacent first connecting columns 12, and the array arrangement of the multiple first connecting columns 12 achieves the interval arrangement of the first positioning hole 11.

[0098] Similarly, the second positioning hole 222 is defined between the two rows and two columns of adjacent second connecting columns 221, and the array arrangement of the multiple second connecting columns 221 achieves the interval arrangement of the second positioning hole 222.

[0099] It can be understood that the first positioning hole 11 and the second positioning hole 222 formed by the multiple first connecting columns 12 and the multiple second connecting columns 221 arranged at intervals can ensure that the multiple battery cells 21 are arranged at intervals, reduce the problem of thermal expansion caused by direct contact of the multiple battery cells 21, and reduce the situation that the multiple battery cells 21 are pressed and deformed due to collision of the energy storage power supply 100, thereby reducing the safety risk.

[0100] In some embodiments, the first connecting column 12 and the second connecting column 221 can be arranged in two rows and two columns, and the first positioning hole 11 and the second positioning hole 222 can be defined between the two rows and two columns of adjacent first connecting columns 12 and the two rows and two columns of adjacent second connecting columns 221 to ensure that the cylindrical battery cell 21 is stably placed, thereby improving the stability of the cylindrical battery cell 21.

[0101] In detail, the outer peripheral wall of each first connecting column 12 and second connecting column 221 forms an arc surface to surround and form the cylindrical first positioning hole 11 and second positioning hole 222, so that the cylindrical hole matches the outer peripheral wall of the battery cell 21, thereby ensuring the connection effect of the battery cell 21 and the positioning part and reducing the shaking phenomenon.

[0102] In other embodiments, the first positioning hole 11 and the second positioning hole 222 can also be other shapes, such as rectangular, etc., to ensure that the different shapes of the battery cell 21 are stably placed, which is not specifically limited here.

[0103] Referring to FIG. 2, in some embodiments, the energy storage power supply 100 further comprises a second electrical connecting member 50, which is arranged on the side of the support 22 opposite to the battery cell 21 and is electrically connected with the plurality of battery cells 21.

[0104] In this way, the second electrical connecting member 50 can balance the current and overvoltage protection, reduce the damage and replacement frequency of the battery cell 21, and thus reduce the maintenance cost of the battery module 20.

[0105] Specifically, the second electrical connecting member 50 is a busbar, which is a kind of equipment with high conductivity, high stability and reliability, used for concentrating or distributing current. In the electrical field, the busbar is also called bus, busbar, etc., used for connecting multiple electrical lines. The busbar is made of high-conductivity material to ensure the efficiency of current transmission. The busbar also has good current carrying and transmission capacity, can quickly respond to power grid changes, and ensure the stable operation of the power grid.

[0106] The second electrical connecting member 50 can connect the positive and negative poles of at least one battery cell 21 alternately, so that the positive and negative poles connected with the two ends of the second electrical connecting member 50 are positive and negative connection ports respectively, that is, the second electrical connecting member 50 is connected in series with at least one battery cell 21, so that at least one battery cell 21 forms a large-voltage output power supply, thereby ensuring that the user's power demand is met.

[0107] In the present embodiment, the second electrical connecting member 50 is in the form of a plate, each second electrical connecting member 50 connects six battery cells 21 to realize the series connection between the six battery cells 21, and the second electrical connecting member 50 can be made of copper, aluminum, nickel or alloy material. After the second electrical connecting member 50 is fixed to the correct position by the working jig, the second electrical connecting member 50 and the electrodes of the battery cell 21 can be welded together by laser welding. It can be understood that the electrical connection between the second electrical connecting member 50 and the electrodes of the battery cell 21 can also be achieved by twisting or pressing, etc.

[0108] In some embodiments, the energy storage power supply 100 further comprises an insulating layer 60 arranged between the first electrical connecting member 30 and the pull rod housing 40.

[0109] In this way, the insulating layer 60 can effectively insulate the first electrical connecting member 30 and the pull rod housing 40, so as to avoid the metal parts on the pull rod housing 40 from accidentally touching the first electrical connecting member 30 to cause electric leakage or short circuit.

[0110] Specifically, in the embodiments of the present application, the main role of the insulation layer 60 is to isolate the electrical connection and the pull rod shell 40, preventing current leakage and short circuit phenomenon. Through the isolation effect of the insulation layer 60, the safety of the power supply during use can be ensured.

[0111] The insulation layer 60 can also play a certain mechanical protection role for the first electrical connection 30 and the pull rod shell 40. It can withstand a certain mechanical pressure and impact force, protecting the internal circuit and structure from damage.

[0112] The insulation layer 60 material usually has excellent heat resistance and corrosion resistance, which can adapt to various complex use environments. This can ensure that the power supply can work normally in various harsh environments, improve the reliability and stability of the power supply.

[0113] The insulation layer 60 material needs to have excellent insulation performance and mechanical strength, and also has good heat resistance and corrosion resistance. Common insulation layer 60 materials include rubber, plastic, ceramic, etc. These materials can effectively isolate the electrical connection and the pull rod shell 40, preventing current leakage and short circuit phenomenon.

[0114] The design of the insulation layer 60 needs to consider the structure and use environment of the power supply. In the embodiments of the present application, the insulation layer 60 should be tightly attached between the electrical connection and the pull rod shell 40 without any gap. At the same time, the thickness of the insulation 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 impact.

[0115] In some embodiments, the energy storage power supply 100 also includes a collection plate 70, and the collection plate 70 is connected with the plurality of first electrical connections 30.

[0116] In this way, the collection plate 70 is beneficial to realize real-time monitoring and data collection of battery parameters.

[0117] Specifically, the collection plate 70 is also called a battery information collector or battery pack collection plate 70 (BIC), which is an important part of the battery management system (BMS). The collection plate 70 connects the battery cells 21 in the battery module 20, and collects the voltage, temperature and other parameters of the battery cells 21 in real time, and transmits these parameters to the BMS. The BMS controls and manages the charging, discharging, thermal management and other aspects of the battery pack according to the collected data, to ensure the safe and efficient operation of the battery pack.

[0118] The acquisition board 70 is mainly responsible for real-time monitoring and collecting the state information of each battery cell 21 in the battery module 20, such as voltage, temperature, etc. Through the collection of these information, the BMS can accurately understand the working state of the battery module 20 and perform corresponding management and control. The acquisition board 70 can accurately collect the voltage, temperature and other parameters 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 state of the battery module 20 in real time, ensuring that the BMS can timely understand the operation of the battery module 20. In addition to the basic voltage and temperature parameters, the acquisition board 70 can also collect other parameters such as current, internal resistance, etc., to provide the BMS with more comprehensive battery module 20 state information. The acquisition board 70 usually uses high-performance and high-reliability electronic components and materials to ensure its stable operation in harsh environments.

[0119] The energy storage power supply 100 can collect the state information of each battery cell 21 through the acquisition board 70. The state information of the battery cell 21 can include the voltage, current and temperature of each battery cell 21. The acquisition board 70 can include a first acquisition board and a second acquisition board. The first acquisition board is connected to the first electrical connection 30. The second acquisition board is connected to the second electrical connection 50. After the first electrical connection 30 and the second electrical connection 50 are welded, the first acquisition board can be fixed to the corresponding position of the first electrical connection 30 by screws, and the second acquisition board can be fixed to the corresponding position of the second electrical connection 50. After the acquisition board 70 is fixed, the nickel strip of the first acquisition board can be connected to the first electrical connection 30 by laser welding or other electrical connection methods, so as to realize the electrical connection between the first acquisition board and the first electrical connection 30. At the same time, the second acquisition board and the second electrical connection 50 can also be connected by the same method.

[0120] Please refer to FIG. 5, in some embodiments, the energy storage power supply 100 further includes an inverter 80, the inverter 80 is provided with a cooling fan, the inverter 80 is electrically connected with the battery module 20 and is installed on the bracket 22.

[0121] In this way, the inverter 80 is used to assist the heat dissipation of the battery module 20, which is conducive to improving the service life of the battery module 20.

[0122] Specifically, the energy storage power supply 100 is a high-integration and high-power device, and the heat dissipation performance is crucial to its stability and safety. In the design of the energy storage power supply 100, the inverter 80 is an indispensable component, especially in the battery module 20 part.

[0123] Since the battery module 20 generates heat during operation, if the heat cannot be effectively dissipated in time, the temperature of the battery module 20 may be increased, thereby affecting the performance and life of the battery, and even causing a safety accident. Therefore, in the embodiments of the present application, the main function of the inverter 80 is to remove the heat generated by the battery module 20 by generating air flow, thereby reducing the temperature of the battery module 20 and ensuring the stable operation of the energy storage power supply 100.

[0124] Further, the inverter 80 is spaced apart from the battery module 20, and the battery module 20 is further provided with a radiator. The inverter 80 and the battery module 20 are spaced apart.

[0125] Further, the inverter 80 is spaced apart from the radiator. The inverter 80 and the radiator are kept at a proper distance, which can ensure that the air flow generated by the fan can fully and uniformly blow through the surface of the radiator, thereby more effectively removing the heat on the radiator.

[0126] The same or similar parts among the various embodiments in the present specification can be referred to each other. In particular, for the device embodiments and the terminal embodiments, since they are basically similar to the method embodiments, the description is relatively simple.

Any change or replacement within the technical scope disclosed by the embodiments of the present application should be covered in the protection scope of the embodiments of the present application.
