[0052] In the related art, energy storage power supplies generally use brackets to fix multiple battery cells to form a battery pack and then install it in a shell. This results in a large number of parts, large volume, high cost, and complicated installation procedures for energy storage power supplies. On the other hand, since installation space needs to be reserved in the shell of the energy storage power supply to install components such as battery packs and inverters, the volume of the energy storage power supply is further increased.

[0053] See also Figure 1 The energy storage power supply 100 of the embodiment of the present application includes:

[0056] The inverter 30 is disposed inside the housing 10 and is electrically connected to the battery cell 20 .

[0057] The energy storage power supply 100 proposed in the present application eliminates the bracket used to fix the battery cells 20 in the traditional energy storage power supply 100, and uses the first part 11 and the second part 12 to fix multiple battery cells 20, which effectively reduces the number of components inside the shell 10, which is beneficial to reducing production costs and assembly difficulty. At the same time, it is beneficial to improve the space utilization inside the energy storage power supply 100 and facilitate the miniaturization of the energy storage power supply 100.

[0058] For details, please refer to Figure 2The 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 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 energy stored in the battery pack into AC energy, and then output it.

[0059] See also Figures 1 to 3 In the embodiment of the present application, the first part 11 and the second part 12 are enclosed to form a receiving cavity, and a plurality of battery cells 20 are arranged in the receiving cavity.

[0062] Furthermore, a avoidance groove is provided on the top of the second part 12 , and the handle 123 is rotatably disposed on the second part 12 , and the avoidance groove is used to accommodate the handle 123 .

[0063] In some embodiments, the handle 123 is made of metal. Specifically, the handle 123 can be made of aluminum alloy with a hollow interior, which is beneficial to lightweighting the energy storage power supply 100. The aluminum alloy handle 123 has high strength and durability, which is beneficial to increasing the reliability of the handle 123 and extending the service life of the handle 123.

[0064] In other embodiments, the handle 123 may also be made of other materials, which may be specifically configured according to actual needs and is not limited here.

[0065] In other embodiments, the handle 123 may also be configured as a flexible handle 123 . The flexible handle 123 has good adaptability and flexibility, and has better comfort and tactile feel.

[0066] See also Figure 4 In some embodiments, a support portion 113 is further provided on the side of the first portion 11 away from the multiple battery cells 20, and an anti-slip structure is further provided on the support portion 113.

[0067] In some embodiments, a fixing groove may be provided on one side of the first portion 11 away from the plurality of battery cells 20 , and a thicker anti-skid pad may be provided in the fixing groove. The material of the anti-skid pad may be selected according to actual needs and is not limited here.

[0068] In some embodiments, the first positioning portion 1111 includes a plurality of first positioning grooves 1112, one end of a plurality of battery cells 20 is inserted into the first positioning groove 1112, the second inner wall 121 is provided with a second positioning portion 1211, the second positioning portion 1211 includes a plurality of second positioning grooves, the other end of the plurality of battery cells 20 is inserted into the second positioning groove.

[0069] In this way, the first positioning groove 1112 and the second positioning groove are used to fix the plurality of battery cells 20 .

[0070] For details, please refer to Figure 5 The first positioning groove 1112 is disposed on the first inner wall 111 of the lower bottom shell. Further, the number of the first positioning grooves 1112 is multiple, and the multiple first positioning grooves 1112 are arranged in an array. In this embodiment, the multiple battery cells 20 are arranged in an array, and one first positioning groove 1112 cooperates to fix one battery cell 20.

[0071] In some embodiments, a second positioning portion 1211 can also be set on the second inner wall 121.

[0072] In some embodiments, in order to further fix the battery cell 20, a fixing glue may be added to the first positioning groove 1112, so that the battery cell 20 is fixed more firmly and the stability of the battery cell 20 is enhanced. When the shell 10 of the energy storage power supply 100 is hit or vibrated, the structural glue can absorb part of the impact force, thereby reducing the impact on the battery cell 20 and avoiding leakage or even explosion caused by the internal electrolyte oscillation due to excessive impact on the battery cell 20. Preferably, the fixing glue can be selected from thermally conductive silicone with good thermal conductivity, so that the thermally conductive silicone can absorb and transfer the heat generated by the battery cell 20 during operation to the shell 10, thereby dissipating heat for telecommunications, which is conducive to reducing the operating temperature of the battery cell 20 and avoiding safety hazards caused by excessive temperature of the battery cell 20.

[0076] Furthermore, the first connecting column 112 and the first portion 11 are an integral structure formed by integral processing, and the second connecting column 122 and the second portion 12 are an integral structure formed by integral processing.

[0077] Further, in the embodiment of the present application, the first connecting column 112 and the second connecting column 122 are detachably connected by a fastener, and the fastener includes a bolt installed on the first connecting column 112 and a nut installed on the second connecting column 122. The bolt is a hexagonal bolt and the nut is a hexagonal nut. Such a configuration can prevent the bolt and the nut from rotating when they are locked. In other embodiments, the bolt and the nut can also be configured as other non-circular cross-section shapes such as a quadrangle or an octagon to prevent the bolt and the nut from rotating.

[0078] In some embodiments, the first connecting column 112 is disposed close to the peripheral wall of the first portion 11 , and the second connecting column 122 is disposed close to the peripheral wall of the second portion 12 .

[0079] In this way, the first connecting column 112 and the second connecting column 122 are arranged close to the peripheral wall of the shell 10, which can prevent the first connecting column 112 and the second connecting column 122 from obstructing the installation of other components inside the shell 10 and facilitate the use of the internal space of the shell 10.

[0080] Specifically, in the embodiment of the present application, there are multiple first connecting columns 112, and the multiple first connecting columns 112 are spaced apart near the peripheral wall of the first portion 11; there are multiple second connecting columns 122, and the multiple second connecting columns 122 are spaced apart near the peripheral wall of the second portion 12.

[0081] In some embodiments, since the lengths of the first connecting column 112 and the second connecting column 122 are relatively long, in order to improve their structural strength, a first reinforcing rib is further provided on the side of the first connecting column 112, one end of the first reinforcing rib is connected to the first inner wall 111, and the other end of the first reinforcing rib is connected to the first connecting column 112. Similarly, a second reinforcing rib is further provided on the side of the second connecting column 122, one end of the second reinforcing rib is connected to the second inner wall 121, and the other end of the second reinforcing rib is connected to the second connecting column 122.

[0102] In other embodiments, the first electrical connector 41 may pass through the bottom wall of the first receiving groove 114 to be electrically connected to the battery cell 20 , and the second electrical connector 42 may pass through the bottom wall of the second receiving groove 124 to be electrically connected to the battery cell 20 .

[0103] In some embodiments, see Figure 7 When the electrodes 21 of the battery cell 20 are all arranged on the same side of the battery cell, it is only necessary to provide a receiving groove on one side of the shell 10 for accommodating the electrical connector 40 .

[0104] See also Figure 3 , Figure 5 and Figure 8 In some embodiments, the housing 10 further includes a cover plate, which is connected to the housing 10 and covers the sealed electrical connector 40 and the through hole.

[0105] In this way, the cover plate is used to enclose the electrical connector 40 in the receiving groove, which is beneficial to protecting the electrical connector 40 and preventing the electrical connector 40 from rusting, falling off, and other problems.

[0106] Specifically, in the embodiment of the present application, the shell 10 also includes a first cover plate 115 and a second cover plate 125. The first cover plate 115 can be detachably mounted on the first part 11 and covers the first receiving groove 114. The second cover plate 125 can be detachably mounted on the second part 12 and covers the second receiving groove 124.

[0107] In the embodiment of the present application, the area of ​​the first cover plate 115 is slightly larger than the opening of the first receiving groove 114. In order to make the top surface of the first part 11 flat and beautiful, the opening edge of the first receiving groove 114 is recessed downward to form a first installation groove, and the first cover plate 115 is installed in the first installation groove. Similarly, the area of ​​the second cover plate 125 is slightly larger than the opening of the second receiving groove 124. In order to make the top surface of the second part 12 flat and beautiful, the opening edge of the second receiving groove 124 is recessed downward to form a second installation groove, and the second cover plate 125 is installed in the second installation groove.

[0108] Furthermore, in an embodiment of the present application, the first cover plate 115 is detachably mounted on the first part 11 by fasteners, and the second cover plate 125 is detachably mounted on the second part 12 by fasteners. In other embodiments, the first cover plate 115 is also detachably mounted on the first part 11 by other detachable connection methods such as snap connections and mortise and tenon connections, and the second cover plate 125 is also detachably mounted on the second part 12 by other detachable connection methods such as snap connections and mortise and tenon connections.

[0109] Furthermore, when the first cover plate 115 covers the first receiving groove 114, a sealing ring can be provided between the first cover plate 115 and the outer side wall of the first part 11 to strengthen the sealing effect of the first receiving groove 114, thereby isolating the first electrical connector 41 in the first receiving groove 114 from external water vapor. In this way, when the energy storage power supply 100 is used in a humid environment, the sealing ring can prevent water vapor from invading the first receiving groove 114, thereby preventing the first electrical connector 41 from rusting or even short-circuiting due to water vapor. Similarly, when the second cover plate 125 covers the second receiving groove 124, a sealing ring can be provided between the second cover plate 125 and the outer side wall of the second part 12 to strengthen the sealing effect of the second receiving groove 124, thereby isolating the second electrical connector 42 in the second receiving groove 124 from external water vapor.

[0110] In some embodiments, see Figure 7 When the electrodes 21 of the battery cell 20 are all arranged on the same side of the battery cell, since a receiving groove for accommodating the electrical connector 40 is provided on one side of the shell 10, only one cover plate needs to be detachably installed on the shell 10 and cover the receiving groove.

[0111] In some embodiments, the inverter 30 includes a substrate 31 and electronic devices disposed on the substrate 31 , and a plane of the substrate 31 is parallel to an extension direction of the battery cell 20 .

[0112] In this way, the plane of the substrate 31 is parallel to the extension direction of the battery cell 20 , which is beneficial to reducing the size of the energy storage power supply 100 .

[0113] Specifically, in some embodiments, the substrate 31 is a PCB circuit board, the substrate 31 is vertically arranged next to the battery cell 20 near the battery cell 20, and a plurality of electronic devices are arranged on the surface of the substrate 31 away from the battery cell 20.

[0114] In some embodiments, the housing 10 is provided with a fixing groove, and the substrate 31 is inserted into the fixing groove to fix the inverter 30 to the housing 10 .

[0115] In this way, fixing the base plate 31 by using the fixing groove is conducive to installing the base plate 31 more firmly.

[0116] Specifically, in some embodiments, the fixing groove fixes the inverter 30 by clamping the substrate 31 . Optionally, the fixing groove may be provided on the inner wall of the first part 11 or the inner wall of the second part 12 .

[0117] In some embodiments, the first portion 11 of the housing 10 is provided with a first fixing groove, and the second portion 12 of the housing 10 is provided with a second fixing groove, and the first fixing groove and the second fixing groove clamp the substrate 31 .

[0118] In this way, using the first fixing groove and the second fixing groove to fix the substrate 31 is conducive to installing the substrate 31 more firmly, and it is also easier to fix the substrate 31.

[0119] Specifically, in some embodiments, the substrate 31 is clamped inside the shell 10 through a first fixing groove and a second fixing groove, thereby fixing the inverter 30. Optionally, the first fixing groove is arranged on the inner wall of the first part 11, and the second fixing groove is arranged on the inner wall of the second part 12.

[0120] See also Figure 3 In some embodiments, the energy storage power supply 100 further includes a battery management system 50 , which is electrically connected to the battery cell 20 and the inverter 30 .

[0121] In this way, setting up the battery management system 50 is beneficial to ensuring the safety of the energy storage power supply 100, extending the life of the energy storage power supply 100, improving the performance of the energy storage power supply 100, and realizing remote monitoring and management of the energy storage power supply 100.

[0122] Specifically, the battery management system 50 (BMS) is a system for intelligently managing and maintaining each battery unit, and can be regarded as the "brain" of the energy storage system. Its main functions are to collect data and record the voltage, current, temperature and other related data of the battery cell 20, monitor and estimate the real-time status of the battery, control the battery charging and discharging process, and perform fault diagnosis and early warning.

[0123] In the embodiment of the present application, the inverter 30 and the battery management system 50 are both disposed between the housing 10 and the battery cell 20 . Furthermore, the inverter 30 and the battery management system 50 are disposed near two adjacent side surfaces of the housing 10 .

[0124] In some embodiments, the energy storage power supply 100 further includes a panel 60 . An opening is formed when the first portion 11 and the second portion 12 are connected. The panel 60 is detachably disposed at the opening 13 .

[0125] In this way, providing an opening can facilitate the installation of the panel 60 and the plugging of the circuits inside the energy storage power supply 100.

[0126] Specifically, in the embodiment of the present application, the housing 10 includes a panel 60, which is disposed at the opening 13 between the first portion 11 and the second portion 12. It is easy to understand that components such as the battery module, the inverter, and the BMS need to be connected by wires, and the housing 10 can be basically formed after the battery cell 20 is fixed. At this time, it is difficult to connect the wires if the opening 13 is not provided.

[0127] Furthermore, the panel 60 can display information such as the current power level and battery temperature of the energy storage power source 100. The panel 60 is also provided with a variety of electrical components, including but not limited to a display screen, a car charging slot, a USB slot, a switch, and an AC socket for directly connecting to an inverter.

[0128] In some embodiments, the energy storage power supply 100 further includes a main board 70 , which is fixed to a side of the panel 60 close to the housing 10 , and the main board 70 is electrically connected to the battery cell 20 .

[0129] In this way, the main board 70 is used to connect the panel 60 and the battery cell 20 , and the charging and discharging of the battery cell 20 can be controlled by operating the panel 60 .

[0130] In the embodiment of the present application, a car charger socket and a USB socket for connecting to the BMS are provided on the main board 70. The main board 70 is arranged between the panel 60 and the battery cell 20. The main board 70 is electrically connected to the battery cell 20 and the inverter 30 respectively. The instructions input by the operator on the panel 60 can be transmitted to the telecommunications and inverter 30 through the main board 70, thereby controlling the charging or discharging process of the battery cell 20 and the inverter 30.
