[0106] In this way, the first support 42 is used to assist in fixing the first battery module 23, so as to avoid the instability caused by the lack of supporting point between the first battery module 23 and the second battery module 24 stacked together.

[0108] Specifically, in some embodiments, the first battery module 23 and the second battery module 24 each comprise a plurality of battery cells 21, and the plurality of battery cells 21 are arranged in a vertical array, that is, the length direction of the battery cells 21 is arranged along the vertical direction, so as to ensure the minimum space occupation.

[0109] In other embodiments, the plurality of battery cells 21 can also be arranged in other directions according to actual needs.

[0110] In other embodiments, the first battery module 23 and the second battery module 24 can also be placed in other ways according to actual needs.

[0111] Referring to FIG. 8, in some embodiments, the energy storage power supply 100 further comprises a second electrical connector 46, which is arranged on the first support 42 and the second support 44 respectively, so as to connect the same side electrodes 211 of the adjacent plurality of battery cells 21.

[0112] Specifically, the second electrical connector 46 can sequentially and alternately connect the positive poles and the negative poles of at least one battery cell 21, so that the positive pole and the negative pole connected with the two ends of the second electrical connector 46 are respectively a positive connection port and a negative connection port, that is, the second electrical connector 46 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 to meet the power demand of the user.

[0113] Referring to FIG. 7, in some embodiments, the first end of the battery cell 21 is provided with two electrodes 211.

[0114] In this way, the electrodes 211 of the two layers of battery cells 21 can be arranged at intervals, so as to avoid the short circuit caused by the mistaken contact of the electrodes 211 of the two layers of battery cells.

[0115] Specifically, in some embodiments, the battery cell 21 has two electrodes 211, and the two electrodes 211 are arranged on the same side of the battery cell 21. When the battery cells 21 are arranged in an array, the electrodes 211 are arranged on the same side of the energy storage power supply, so as to facilitate the connection between the battery cells 21.

[0117] Further, since the electrodes 211 of the battery cells 21 of the first battery module 23 are arranged opposite to the electrodes 211 of the battery cells 21 of the second battery module 24, an insulating layer needs to be arranged between the two energy storage power supplies to avoid the misconnection of the battery cells 21 between the upper and lower energy storage power supplies, and to avoid the short circuit of the energy storage power supply.

[0118] In some embodiments, the second ends of the battery cells 21 of the first battery module 23 can be inserted into the first positioning portion 1112, and the second ends of the battery cells 21 of the second battery module 24 can be inserted into the second positioning portion 1213. Since the electrodes 211 are arranged on the same side of the energy storage power supply, when the two energy storage power supplies are stacked, the electrodes 211 of the two energy storage power supplies are arranged opposite to each other, so that the insulating layer does not need to be arranged between the two energy storage power supplies, thereby reducing the production cost and the assembly difficulty.

[0119] In some embodiments, the battery cell 21 has two electrodes 211, and the two electrodes 211 can be arranged on opposite sides of the battery cell 21. When the battery cells 21 are arranged in an array, the electrodes 211 are arranged on opposite sides of the energy storage power supply, so as to facilitate the connection between the battery cells 21.

[0120] Further, since the electrodes 211 are arranged on opposite sides of the energy storage power supply, when the two energy storage power supplies are stacked in a vertical direction, an insulating layer needs to be arranged between the two energy storage power supplies to avoid the misconnection of the battery cells 21 between the upper and lower energy storage power supplies, and to avoid the short circuit of the energy storage power supply.

[0121] Referring to FIG. 6, in some embodiments, the battery module 20 further includes a connecting piece 22, which is used to connect the first battery module 23 and the second battery module 24.

[0122] In this way, the connecting piece 22 connects and fixes the first battery module 23 and the second battery module 24, thereby facilitating the assembly of the battery module 20, and facilitating the reduction of the assembly difficulty of the energy storage power supply 100.

[0123] Specifically, the connecting piece 22 is a sheet metal part. The sheet metal part refers to a metal product processed by a specific sheet metal process. This process is mainly aimed at metal sheets (usually below 6mm), including a series of comprehensive cold processing procedures such as shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. The sheet metal part is characterized by the same thickness of the same part. The sheet metal part has the characteristics of light weight, high strength, good electrical conductivity (can be used for electromagnetic shielding), low cost, and is suitable for mass production.

[0124] In this way, the sheet metal part generally has high tensile strength and compressive strength, which is beneficial to improve the service life of the connecting piece 22, and the sheet metal part has high processing efficiency, which is beneficial to shorten the processing period.

[0125] In the embodiments of the present application, the connecting piece 22 is processed and formed by shearing and bending, and burrs that may occur during processing are removed, and the sharp corner part of the connecting piece 22 is rounded, thereby preventing the connecting piece 22 from injuring the hands of the operator during assembly or maintenance.

[0127] In some embodiments, the connecting piece 22 is made of a galvanized sheet.

[0128] In this way, the galvanized sheet has relatively high strength and durability, which is beneficial to improve the service life of the connecting piece 22.

[0129] Specifically, the galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface of the steel sheet to prevent the surface of the steel sheet from being corroded and prolong its service life.

[0130] In the embodiments of the present application, the connecting piece 22 is made of a galvanized sheet and processed by a sheet metal process. It should be noted that before the galvanized sheet is subjected to sheet metal processing, it is necessary to ensure that the surface of the galvanized sheet is clean, free of oil stains, rust and impurities. These impurities may affect the processing accuracy and product quality. In addition, it is also necessary to check whether the galvanized layer is uniform and has no peeling phenomenon. An uneven galvanized layer may affect the corrosion resistance and appearance of the product.

[0131] When the galvanized sheet is subjected to sheet metal processing, the knife mark generated during the punching process should meet the safety requirements (not scratch the hand) and the part size tolerance, which is generally not more than 10% to 20% of the thickness of the sheet. The depth of the knife mark generated during the bending process should be controlled within 0.3mm.

[0132] In other embodiments, the connecting piece 22 can also be made of other metal materials and processed by a sheet metal process. The specific metal material can be selected according to actual needs, which is not limited here. In other embodiments, the connecting piece 22 can also be made of other metal materials and processed by a sheet metal process. The specific metal material can be selected according to actual needs, which is not limited here.

The other end of the plurality of battery cells 21 abuts against the second inner wall 1212 to fix the plurality of battery cells 21 to the first positioning portion 1112. The inverter 30 is disposed inside the housing 10 and is electrically connected to the battery cells 21.

[0136] The energy storage power supply 100 according to the present application cancels the bracket for fixing the battery cells 21 in the conventional energy storage power supply 100 and uses the first shell 11 and the second shell 12 to fix the plurality of battery cells 21. This effectively reduces the number of components inside the housing 10, which is conducive to reducing production costs and assembly difficulty. At the same time, this is conducive to improving the space utilization inside the energy storage power supply 100 and facilitating the miniaturization of the energy storage power supply 100.

[0137] Specifically, referring to FIG. 12, the energy storage power supply 100 is a device capable of storing electrical energy and releasing it when needed. Its main function is to provide 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 first converts the direct current electrical energy stored in the battery pack into alternating current electrical energy and then outputs it.

[0138] Referring to FIGS. 11-13, in the embodiment of the present application, the first shell 11 and the second shell 12 enclose a receiving cavity, and the plurality of battery cells 21 are disposed in the receiving cavity.

[0140] In the embodiment of the present application, the second shell 12 is provided with a handle 1211 for moving and carrying the energy storage power supply 100.

[0141] Further, the second shell 12 is provided with an avoiding groove at the top, and the handle 1211 is rotatably arranged on the second shell 12, and the avoiding groove is used for accommodating the handle 1211.

[0142] In some embodiments, the handle 1211 is made of metal, and specifically, the handle 1211 can be made of aluminum alloy, and the inside of the handle 1211 is hollow, which is beneficial to the lightweight of the energy storage power supply 100, and the strength and durability of the aluminum alloy handle 1211 are relatively high, which is beneficial to increasing the reliability of the handle 1211 and prolonging the service life of the handle 1211.

[0143] In other embodiments, the handle 1211 can also be made of other materials, and specifically, the handle 1211 can be made of other materials according to actual needs, which are not limited herein.

[0144] In other embodiments, the handle 1211 can also be made of a flexible handle 1211, and the flexible handle 1211 has good adaptability and flexibility, and has better comfort and touch.

[0145] Please refer to FIG. 14, in some embodiments, the side of the first shell 11 away from the plurality of battery cells 21 is further provided with a supporting portion 116, and the supporting portion 116 is further provided with an anti-skid structure, which can be an anti-skid silica gel pad, an anti-skid rubber pad, or an anti-skid pattern provided on the supporting portion 116.

[0146] In some embodiments, the side of the first shell 11 away from the plurality of battery cells 21 can also be provided with a fixing groove, and a relatively thick anti-skid pad is arranged in the fixing groove, and the material of the anti-skid pad can be selected according to actual needs, which are not limited herein.

[0147] In some embodiments, the first positioning portion 1112 includes a plurality of first positioning grooves 11121, one end of the plurality of battery cells 21 is inserted into the first positioning groove 11121, the second inner wall 1212 is provided with a second positioning portion 1213, the second positioning portion 1213 includes a plurality of second positioning grooves, and the other end of the plurality of battery cells 21 is inserted into the second positioning groove.

[0148] In this way, the first positioning groove 11121 and the second positioning groove are used for fixing the plurality of battery cells 21.

[0149] Specifically, please refer to FIG. 15, the first positioning groove 11121 is arranged on the first inner wall 1111 of the lower bottom shell. Further, the number of the first positioning grooves 11121 is a plurality, and the plurality of first positioning grooves 11121 are arrayed, and in this embodiment, the plurality of battery cells 21 are arrayed, and one first positioning groove 11121 is matched to fix one battery cell 21.

The plurality of second positioning grooves are arranged in an array, and the plurality of battery cells 21 are arranged in an array. One second positioning groove is matched with one battery cell 21.

[0151] In some embodiments, to further fix the battery cells 21, the first positioning grooves 11121 can also be filled with fixing glue, so that the battery cells 21 are fixed more firmly and the stability of the battery cells 21 is enhanced. When the shell 10 of the energy storage power supply 100 is subjected to impact or vibration, the structural glue can absorb part of the impact force, thereby reducing the impact on the battery cells 21, avoiding leakage or even explosion caused by excessive impact on the battery cells 21 and internal electrolyte oscillation. Preferably, the fixing glue can be heat-conducting silicone glue with good heat conduction effect. In this way, the heat-conducting silicone glue can absorb and transfer the heat generated by the battery cells 21 during work to the shell 10, thereby dissipating heat for the battery cells 21, which is conducive to reducing the working temperature of the battery cells 21 and avoiding safety hazards caused by excessive temperature of the battery cells 21.

[0152] Please refer to FIG. 14 and FIG. 16. In some embodiments, the first shell 11 includes a plurality of first connecting columns 1113, and the second shell 12 includes a plurality of second connecting columns 1214.

[0156] Further, in the embodiments of the present application, the first connecting columns 1113 and the second connecting columns 1214 are detachably connected by fasteners, and the fasteners include a bolt mounted on the first connecting column 1113 and a nut mounted on the second connecting column 1214. The bolt is a hexagonal bolt, and the nut is a hexagonal nut. In this way, the bolt and the nut can be prevented from rotating when they are locked and matched. In other embodiments, the bolt and the nut can also be provided in other cross-sectional non-circular shapes such as quadrilateral or octagonal shapes to avoid rotation of the bolt and the nut.

[0157] In some embodiments, the first connecting column 1113 is arranged close to the peripheral wall of the first shell 11, and the second connecting column 1214 is arranged close to the peripheral wall of the second shell 12.

[0158] In this way, the first connecting column 1113 and the second connecting column 1214 are arranged close to the peripheral wall of the shell 10, which can avoid the first connecting column 1113 and the second connecting column 1214 from hindering the installation of other elements inside the shell 10, and facilitate the utilization of the internal space of the shell 10.

[0159] Specifically, in the embodiments of the present application, the number of the first connecting column 1113 is multiple, and the multiple first connecting columns 1113 are arranged at intervals close to the peripheral wall of the first shell 11.
