The BMS can be electrically connected to the second acquisition board 56, so that the parameter information of the battery cells 14 can be collected through the second acquisition board 56.

[0086] The material of the second collecting plate 56 includes, but is not limited to, copper, aluminum, nickel, or alloy materials. Optionally, the second collecting plate 56 can be connected to the second bus bar 50 by welding (such as laser welding).

[0087] In some embodiments, please combine Figure 5 、 Figure 6 and Figure 8 The energy storage power supply 100 includes a battery management circuit board 44, which is disposed in the accommodating cavity 18. The first bus 32 is electrically connected to the battery management circuit board 44, and the inverter 16 is disposed on a side of the battery management circuit board 44 away from the first bus 32.

[0088] Therefore, the battery management circuit board 44 can collect parameter information of the battery cells 14 through the first bus 32 .

[0089] Specifically, the battery management circuit board 44 includes a BMS, which can be electrically connected to the first bus 32. In this embodiment, the battery management circuit board 44 can be electrically connected to the first bus 32 via the first acquisition board 40, thereby collecting parameter information (including but not limited to voltage, current, temperature, etc.) of the battery cells 14. The BMS can control the operation of the energy storage power supply 100 based on the parameter information of the battery cells 14. Optionally, the battery management circuit board 44 is fixedly connected to the second bracket 46 by bolts.

[0090] Optionally, the battery management circuit board 44 may be electrically connected to the second bus 50 via the second acquisition board 56 , thereby acquiring parameter information (including but not limited to voltage, current, temperature, etc.) of the battery cell 14 .

[0091] Optionally, the energy storage power supply 100 includes an isolation sheet 58 , which is disposed between the battery management circuit board 44 and the second busbar 50 , and between the battery management circuit board 44 and the second acquisition board 56 . This ensures a certain degree of insulation between the battery management circuit board 44 and the second busbar 50 and the second acquisition board 56 . The isolation sheet 58 can be made of an insulating material or coated with an insulating layer. Insulating materials include, but are not limited to, plastic, mica sheets, and the like.

[0092] Optionally, the battery management circuit board 44 includes two first connectors, the second acquisition board 56 is provided with a second connector, and the first acquisition board 40 is provided with a third connector. The first connector can connect one first connector and the second connector, and the second connector can connect another first connector and the third connector, thereby forming an electrical connection path.

[0093] In some embodiments, a third through hole 57 is further provided on the side wall of the accommodating cavity 18 . The third through hole 57 connects the accommodating space and the accommodating cavity 18 . The first bus 32 is electrically connected to the battery management circuit board 44 through the third through hole 57 .

[0094] Therefore, the provision of the third through hole 57 can facilitate the routing of wires inside the housing 12 so as to electrically connect the first bus 32 to the battery management circuit board 44 .

[0095] Specifically, please combine Figure 9 The third through hole 57 is provided on the bottom surface of the accommodating cavity 18 , the first acquisition board 40 is electrically connected to the first bus 32 , and the first acquisition board 40 can be electrically connected to the battery management circuit board 44 through the third through hole 57 .

[0096] For example, a third connector is provided on the first acquisition board 40, and the third connector can extend into the third through hole 57. One end of the second connector can be connected to the third connector through the third through hole 57, and the other end can be connected to the first connector of the battery management circuit board 44, thereby realizing electrical connection between the first bus 32 and the battery management circuit board 44.

[0097] The first bus 32 is electrically connected to the battery management circuit board 44 through the third through hole 57. The side wall of the accommodating cavity 18 is provided with the third through hole 57, which fully utilizes the space of the energy storage power supply 100 and is conducive to improving the space utilization rate of the energy storage power supply 100.

[0098] In some embodiments, the first pole portion 36 is further provided with an explosion-proof valve 59 , and the explosion-proof valve 59 is connected to the accommodating space through the first through hole 34 .

[0099] Therefore, when the battery cell 14 experiences thermal runaway, the material ejected from the explosion-proof valve 59 can be sprayed into the accommodating space through the first through hole 34 , thereby preventing the thermal runaway from spreading to a certain extent.

[0100] Specifically, during operation, the battery cell 14 may release gas from its interior, causing the pressure inside the battery cell 14 to increase. When the pressure is high, the explosion-proof valve 59 can rupture to release the substances (such as gas, liquid, etc.) inside the battery cell 14. The explosion-proof valve 59 is connected to the accommodating space through the first through-hole 34. The substances ejected from the explosion-proof valve 59 can be sprayed into the accommodating space. The accommodating space isolates the substances ejected from the explosion-proof valve 59 from the other battery cells 14 in the accommodating space, thereby preventing the thermal runaway of a battery cell 14 from spreading to other battery cells 14 to a certain extent, thereby improving the safety of the energy storage power supply 100.

[0101] In some embodiments, the inverter 16 is disposed on a side of the second bracket 46 facing away from the battery cells 14 .

[0102] As a result, the number of components of the energy storage power supply can be reduced.

[0103] Specifically, please combine Figure 5 、 Figure 6 and Figure 8 The first bracket 20 and the second bracket 46 can clamp the battery cell 14 in the vertical direction. The inverter 16 is located on the side of the second bracket 46 facing away from the battery cell 14. Therefore, the second bracket 46 can be used to fix the inverter 16, which can reduce the number of additional components for fixing the inverter 16. This can also reduce the size and weight of the energy storage power supply 100 to a certain extent, improve the portability of the energy storage power supply 100, and reduce the manufacturing cost of the energy storage power supply 100.

[0104] In some embodiments, please combine Figure 5 、 Figure 6 and 8 A plurality of connection sockets 60 are protruding from a side surface of the second bracket 46 facing away from the battery cell 14 , and the inverter 16 is mounted on the plurality of connection sockets 60 .

[0105] Thereby, the heat dissipation space of the inverter 16 can be increased.

[0106] Specifically, when the inverter 16 is operating, it converts the DC power output by the battery cells 14 into AC power for external transmission. During this operation, the inverter 16 generates a significant amount of heat, requiring heat dissipation. The inverter 16 is mounted on multiple connectors 60, allowing it to be spaced farther from the battery management circuitry, increasing the space available for heat dissipation.

[0107] Optionally, the inverter 16 can be mounted on the connecting base 60 by means of bolts, snaps, etc.

[0108] Optionally, a plurality of connection sockets 60 form an accommodation space 62 , and the battery management circuit board 44 and the isolation sheet 58 are located in the accommodation space 62 , which is beneficial to improving the space utilization of the energy storage power supply 100 .

[0109] In some embodiments, please combine Figure 3 The first bracket 20 is provided with a first connecting member 64 , and the second bracket 46 is provided with a second connecting member 66 . The first connecting member 64 is connected to the second connecting member 66 so that the first bracket 20 and the second bracket 46 clamp the battery cell 14 .

[0110] In this way, the structural strength of the connecting piece can be guaranteed to a certain extent.

[0111] Specifically, the first connecting member 64 and the second connecting member 66 are both in the shape of long strips, with the length of the first connecting member 64 extending in the direction close to the second bracket 46, and the length of the second connecting member 66 extending in the direction close to the first bracket 20. The first connecting member 64 and the second connecting member 66 can be connected by means including but not limited to bolts, snaps, etc. Figure 3 The first connecting member 64 and the second connecting member 66 are connected by bolts.

[0112] Optionally, the number of first connectors 64 and second connectors 66 is the same, and both are multiple. Multiple first connectors 64 are arranged along the edge of the first bracket 20, and multiple second connectors 66 can be arranged along the edge of the second bracket 46. Each first connector 64 is connected to a corresponding second connector 66, thereby increasing the connection stability between the first bracket 20 and the second bracket 46.

[0113] Compared with the case where the connecting member only extends from the first bracket 20 or the second bracket 46, which will result in a longer overall length of the connecting member and affect the strength of the connecting member, in the embodiment of the present invention, the first bracket 20 and the second bracket 46 are connected by the first connecting member 64 and the second connecting member 66, and the length of the first connecting member 64 and the second connecting member 66 can be shorter, thereby ensuring the structural strength of the connecting member to a certain extent.

[0114] Optionally, the first connecting member 64 and the second connecting member 66 may be detachably connected.

[0115] In some embodiments, please combine Figure 6 The housing 12 includes a first shell 22 and a second shell 24 . The first shell 22 is connected to the second shell 24 . The first bracket 20 and the first shell 22 are integrally formed.

[0116] Thus, the stability of fixing the battery cell 14 can be improved to a certain extent.

[0117] Specifically, one end of the battery cell 14 is mounted on the first bracket 20 . The first bracket 20 and the first shell 22 are integrally formed. The connection between the first bracket 20 and the first shell 22 is relatively stable, thereby improving the stability of fixing the battery cell 14 to a certain extent.

[0118] Optionally, the housing 12 may be made of plastic, and the first shell 22 and the first bracket 20 may be manufactured integrally through an injection molding process, thereby improving efficiency and reducing costs.

[0119] In some embodiments, a handle 97 is provided on the second shell 24 .

[0120] This makes it convenient for users to move the energy storage power supply 100 .

[0121] Specifically, the energy storage power supply 100 can be movably placed in different places. When a user moves the energy storage power supply 100, the user can carry the energy storage power supply 100 by the carrying handle 97, so that the user can move the energy storage power supply 100 conveniently.

[0122] Optionally, in one embodiment, please combine Figures 1 to 9 The handle 97 is a split handle rotatably provided on the second shell 24. Optionally, in one embodiment, the handle 97 is a handle 97 integrally formed with the second shell 24. The material of the handle 97 can be the same as that of the second shell 24, or it can be different.

[0123] In some embodiments, please combine Figures 3 to 7 A first connecting column 68 is provided in the first shell 22 , and a second connecting column 70 is provided in the second shell 24 . The first connecting column 68 is connected to the second connecting column 70 to connect the first shell 22 and the second shell 24 .

[0124] In this way, the structural strength of the connecting column can be guaranteed to a certain extent.

[0125] Specifically, the first connecting post 68 and the second connecting post 70 are both long and narrow, with the first connecting post 68 extending toward the second shell 24, and the second connecting post 70 extending toward the first shell 22. The first connecting post 68 and the second connecting post 70 can be connected by means including, but not limited to, bolts, snap fasteners, and the like.

[0126] Optionally, the number of first connecting posts 68 and second connecting posts 70 is the same, and both are multiple. Multiple first connecting posts 68 are disposed along a position close to the side wall of the first shell 22, and multiple second connecting posts 70 are disposed along a position close to the side wall of the second shell 24. Each first connecting post 68 is connected to a corresponding second connecting post 70, thereby increasing the connection stability between the first bracket 20 and the second bracket 46.

[0127] Compared with the case where the connecting column only extends from the first shell 22 or the second shell 24, which will result in a longer overall length of the connecting column and affect the strength of the connecting column, in the embodiment of the present invention, the first shell 22 and the second shell 24 are connected by the first connecting column 68 and the second connecting column 70. The length of the first connecting column 68 and the second connecting column 70 can be shorter, thereby ensuring the structural strength of the connecting column to a certain extent.

[0128] In some embodiments, please combine Figure 4 and Figure 8 The first connecting column 68 has a first connecting hole 72 , the second connecting column 70 has a second connecting hole 74 , and a third connecting member (not shown) connects the first connecting column 68 and the second connecting column 70 through the first connecting hole 72 and the second connecting hole 74 .

[0129] Thus, the first connecting pillar 68 and the second connecting pillar 70 can be connected.

[0130] Specifically, in one embodiment, one of the first connecting hole 72 and the second connecting hole 74 can be a through hole, and the other can be a screw hole. The third connecting member may include a bolt, which can pass through the through hole and be connected to the screw hole, thereby connecting the first connecting column 68 and the second connecting column 70.

[0131] In one embodiment, the first connecting hole 72 and the second connecting hole 74 are both screw holes, and the third connecting member may include a bolt, which can be connected to the screw hole of the first connecting column 68 and the screw hole of the second connecting column, thereby connecting the first connecting column 68 and the second connecting column 70.

[0132] In one embodiment, the first connecting hole 72 and the second connecting hole 74 are both through holes, and the third connecting member may include a pin, which can pass through the through hole of the first connecting column 68 and the through hole of the second connecting column and be connected with the two through holes by interference fit, thereby connecting the first connecting column 68 and the second connecting column 70.

[0133] Alternatively, the first connecting post 68 and the second connecting post 70 may be detachably connected. Alternatively, the first shell 22, the first connecting post 68, the first connector 64 and the first bracket 20 may be integrally formed. The second shell 24 and the second connecting post 70 may be integrally formed.

[0134] In some embodiments, please combine Figures 1 to 8 The energy storage power supply 100 includes a panel 26 , the housing 12 is provided with a first opening 76 , and the panel 26 is installed at the first opening 76 .

[0135] Thus, the panel 26 can be formed separately from the shell 12, which can reduce the types of materials and improve the versatility of the materials.

[0136] Specifically, the panel 26 is provided with a current output port (such as an AC output port), and the panel 26 is installed at the first opening 76. The panel 26 and the housing 12 can be separately molded. Because the AC output ports of the energy storage power supply 100 in different countries may be different, the difference in appearance of the energy storage power supply 100 in different countries is mainly in the position of the panel 26, while the other parts are basically the same. In the embodiment of the present utility model, the panel 26 can be separately molded, so the housing 12 of the energy storage power supply 100 in different countries only needs to produce and design different panels 26, and there is no need to produce and design different specifications for the entire housing 12. This can reduce the variety of materials and improve the versatility of the materials.

[0137] Optionally, the panel 26 can be detachably mounted at the first opening 76 to facilitate maintenance of the panel. Optionally, in other embodiments, the panel 26 can also be integrally formed with the housing 12 (such as the first housing 22 or the second housing 24).

[0138] In this embodiment of the present invention, the first shell 22 and the second shell 24 are arranged vertically, with the battery cells 14 arranged vertically. The first shell 22, battery cells 14, second bracket 46, battery management circuit board 44, inverter 16, and second shell 24 are arranged in order from bottom to top. The panel 26 is disposed on the side of the energy storage power supply 100. The cover plate 42 is disposed at the bottom of the energy storage power supply 100. Because a gap may exist at the junction of the cover plate 42 and the first shell 22, which would affect the product appearance, it is difficult to see when it is disposed at the bottom of the energy storage power supply 100. In addition, the weight of the energy storage power supply 100 itself can strengthen the connection between the cover plate 42 and the second shell 24, enhancing the sealing performance.

[0139] In some embodiments, please combine Figure 4 and Figure 7 The shell 12 includes a first shell 22 and a second shell 24. The first shell 22 is provided with a first groove 78, and the second shell 24 is provided with a second groove 80.

The two first connecting pieces are respectively inserted into the first connecting groove 82 and the second connecting groove 84 so that the panel 26 is installed at the first opening 76.

[0140] Thus, the panel 26 can be installed at the first opening 76 through the first connecting piece and the second connecting groove 84 .

[0141] Specifically, in this embodiment, the first shell 22 and the second shell 24 are connected by the first connecting post 68 and the second connecting post 70. The first connecting post 68 is provided with a first connecting groove 82 near the first opening 76, and the second connecting post 70 is provided with a second connecting groove 84 near the first opening 76. The two first connecting pieces on the panel 26 are respectively inserted into the first connecting groove 82 and the second connecting groove 84, so that the panel 26 is installed at the first opening 76.

[0142] Optionally, fasteners may be used to fix the panel 26 so that the panel 26 is not easily dropped from the housing 12 .

[0143] Furthermore, the first connecting column 68 and the second connecting column 70 are provided with a slot near the first opening 76 , and a buckle is provided on the periphery of the panel 26 , and the panel 26 is snapped into the first opening 76 through the connection between the buckle and the slot.

[0144] In some embodiments, the housing 12 is provided with a second opening 86 , and the energy storage power supply 100 includes a ventilation plate 88 , which is installed at the second opening 86 .

[0145] Therefore, the heat dissipation performance of the energy storage power supply 100 can be improved to a certain extent.

[0146] Specifically, the ventilation sheet 88 is provided with ventilation holes, and the accommodating cavity 18 of the shell 12 can be connected with the outside of the shell 12 through the ventilation holes, so that air can circulate inside and outside the shell 12, thereby improving the heat dissipation performance of the energy storage power supply 100 to a certain extent.

[0147] In one embodiment, please combine Figure 4 and Figure 7 The shell 12 includes a first shell 22 and a second shell 24. The first shell 22 is provided with a third groove 90, and the second shell 24 is provided with a fourth groove 92. The first shell 22 is connected to the second shell 24 so that the third groove 90 is connected to the fourth groove 92 to form a second opening 86 of the shell 12. The first connecting column 68 is provided with a third connecting groove 94 near the second opening 86, and the second connecting column 70 is provided with a fourth connecting groove 96 near the second opening 86. Two second connecting plates are provided on the ventilation plate 88, and the two second connecting plates are respectively inserted into the third connecting groove 94 and the fourth connecting groove 96 so that the ventilation plate 88 is installed at the second opening 86.

[0148] Please combine Figure 4 and Figure 7The energy storage power supply 100 is provided with two ventilation fins 88, and the two ventilation fins 88 are respectively provided at the second openings 86 on the left and right sides of the shell 12. The energy storage power supply 100 includes two heat dissipation fans 98 installed on the inverter 16, one heat dissipation fan 98 is close to the ventilation fin 88 on the left, and the other heat dissipation fan 98 is close to the ventilation fin 88 on the right. Optionally, the two heat dissipation fans 98 can blow air in the same direction, such as blowing air to the left when working, forming an airflow from the right ventilation fin 88 to the left ventilation fin 88 inside the shell 12, and dissipating heat to the electrical components in the shell 12 (including but not limited to the inverter 16, battery cell 14, etc.). Optionally, the heat dissipation fan 98 can also be provided on the second bracket 46. The present invention does not specifically limit the number of heat dissipation fans 98.

[0149] Furthermore, the first connecting column 68 and the second connecting column 70 are provided with a slot near the second opening 86 , and the outer periphery of the ventilation piece 88 is provided with a buckle, which is connected to the slot by the buckle so that the ventilation piece 88 is snapped into the second opening 86 .

[0150] In one embodiment, the ventilation piece 88 can be integrally formed with the first shell 22 or the second shell 24. In one embodiment, the ventilation piece 88 can be detachably mounted at the second opening 86.

[0151] Optionally, a foot pad 95 is provided at the bottom of the cover 42, and the foot pad 95 can play an anti-slip and support function.
