[0028] As an optional technical solution of an embodiment of the present application, the energy storage device includes a seal, and the seal is arranged at the connecting portion.

[0029] In the above technical solution, a seal is provided on the connection part to seal the gap between the connection part and the panel or between the connection part and the energy storage bin, thereby reducing the risk of rainwater, sand and gravel, and small animals entering the energy storage bin.

[0030] As an optional technical solution of an embodiment of the present application, a sealing member is provided on the sealing member, and the sealing member is at least partially sealed between the energy storage bin and the sealing member; and / or the sealing member is at least partially sealed between the panel and the sealing member.

[0031] In the above technical solution, a seal is provided to seal the gap between the energy storage bin and the blocking member and / or the gap between the sealing panel and the blocking member, thereby reducing the risk of rainwater, sand and gravel, and small animals entering the energy storage bin.

[0033] In the above technical solution, the heat exchange device can provide heat exchange medium to the battery so as to achieve thermal management of the battery. By providing a first air outlet on the panel, the heat exchange device can directly take in or exhaust air from the first air outlet. Since the number of panels is reduced, the obstruction of the heat exchange device for taking in or exhausting air is reduced, and the resistance is reduced, which is conducive to increasing the air volume of the heat exchange device and improving the cooling capacity and heat exchange efficiency of the heat exchange device.

[0034] As an optional technical solution of the embodiment of the present application, a shielding member is provided on the panel, and the shielding member is used to shield the first air outlet.

[0035] In the above technical solution, a shielding member is provided to shield the first air outlet, thereby reducing the risk of foreign matter or liquid entering the heat exchange device through the first air outlet.

[0036] As an optional technical solution of the embodiment of the present application, the shielding member is formed with a fluid channel, one end of the fluid channel is connected to the first air outlet, and the other end of the fluid channel extends to the bottom of the shielding member.

[0037] In the above technical solution, air enters the fluid channel from the bottom of the shielding member, and enters the heat exchange device through the first air outlet to achieve air intake. Since the other end of the fluid channel extends to the bottom of the shielding member, it is difficult for foreign impurities or liquids to enter the fluid channel from the bottom of the shielding member, and it is even more difficult to reach the first air outlet through the fluid channel, thereby reducing the risk of foreign impurities or liquids entering the heat exchange device, which is conducive to the stable operation of the heat exchange device, improving the heat exchange efficiency of the heat exchange device, and improving the life of the heat exchange device.

[0038] As an optional technical solution of the embodiment of the present application, a plurality of the first air outlets are provided on the panel, and each of the first air outlets is provided with a shielding member.

[0039] In the above technical solution, by setting a plurality of first air outlets on the panel, the heat exchange device can directly take in air from the plurality of first air outlets, and the air intake of the heat exchange device is less blocked and the resistance is reduced, which is conducive to increasing the air volume of the heat exchange device and improving the cooling capacity and heat exchange efficiency of the heat exchange device. Each first air outlet is provided with a shielding member to reduce the risk of foreign impurities or liquids entering the heat exchange device from the first air outlet.

[0040] As an optional technical solution of the embodiment of the present application, multiple first air outlet arrays are distributed.

[0041] In the above technical solution, by arranging the multiple first air outlets in an array, the mutual influence of the multiple first air outlets is reduced, which is beneficial to air intake.

[0042] As an optional technical solution of the embodiment of the present application, the panel is provided with a filter, and the filter is used to filter impurities in the gas passing through the first air outlet.

[0043] In the above technical solution, by setting a filter element, impurities in the gas passing through the first air outlet are filtered out, reducing the risk of impurities entering the heat exchange device, which is conducive to the stable operation of the heat exchange device, improving the heat exchange efficiency of the heat exchange device, and increasing the life of the heat exchange device.

[0044] As an optional technical solution of the embodiment of the present application, the filter element is detachably connected to the panel.

[0045] In the above technical solution, by detachably connecting the filter element to the panel, the filter element can be easily removed for cleaning, or when the filter element is damaged, the filter element can be removed and replaced.

[0046] As an optional technical solution of an embodiment of the present application, the panel is provided with a receiving space, the filter element is at least partially received in the receiving space, and the receiving space is formed with a socket on the outer surface of the panel for the filter element to enter or exit the receiving space.

[0047] In the above technical solution, the filter element and the panel are detachably connected by plugging. When installing the filter element, it is only necessary to insert the filter element from the socket into the receiving space. When removing the filter element, it is only necessary to pull the filter element out of the socket from the receiving space, which is simple and convenient.

[0048] As an optional technical solution of an embodiment of the present application, the socket is located at the top of the panel.

[0049] In the above technical solution, the socket is arranged at the top of the panel, and the filter is at least partially accommodated in the accommodation space under the action of gravity, and is not easy to be separated from the accommodation space from the socket.

[0050] As an optional technical solution of the embodiment of the present application, the filter element is arranged on a side of the panel facing the interior of the shell.

[0051] In the above technical solution, by arranging the filter element on the side of the panel facing the inside of the shell, the filter element is less likely to be damaged and less likely to be dirty than arranging the filter element on the side of the panel facing away from the inside of the shell.

[0052] As an optional technical solution of the embodiment of the present application, the panel is provided with a snap-in component, and the snap-in component is used to lock or unlock the panel and the filter element.

[0053] In the above technical solution, when the clamp locks the panel and the filter, the relative position of the filter and the panel is limited, and the filter cannot be separated from the panel. When the clamp unlocks the panel and the filter, the filter can be separated from the panel, thereby achieving disassembly.

[0054] As an optional technical solution of an embodiment of the present application, the panel is connected to the energy storage bin.

[0055] In the above technical solution, by connecting the panel to the energy storage bin, it is possible to set only the second opening on the shell without changing the energy storage bin and the production line for producing the energy storage bin does not need to be changed, which is beneficial to reduce the production cost of the energy storage device.

[0056] As an optional technical solution of an embodiment of the present application, the energy storage bin includes a plurality of the first openings, the shell includes a plurality of the second openings, and the energy storage device includes a plurality of the panels, each of the panels covering at least one of the first openings and at least one of the second openings.

[0057] In the above technical solution, the functional cabinet and the energy storage bin share multiple panels at multiple locations, which reduces the number of panels and reduces the production cost of the energy storage device.

[0058] As an optional technical solution of an embodiment of the present application, the multiple panels include a first panel and a second panel, the functional cabinet is a heat exchange device, a first air outlet is provided on the first panel, the first air outlet is used to supply air to the heat exchange device, and a second air outlet is provided on the second panel, the second air outlet is used to supply air to the heat exchange device.

[0059] In the above technical solution, the heat exchange device and the energy storage bin of the energy storage device share the first panel and the second panel (equivalent to sharing the air inlet panel and / or the air outlet panel). The first panel and the second panel can still provide a good protective effect on the internal components of the shell, and will not cause a significant weakening of the protective effect. Since the first panel and the second panel are shared, the number of panels is reduced, and the production cost of the energy storage device can be reduced. The first panel is provided with a first air outlet, and the heat exchange device can directly take in or exhaust air from the first air outlet. Since the number of panels is reduced, the obstruction of the air inlet or exhaust of the heat exchange device is reduced, and the resistance is reduced, which is conducive to increasing the air volume of the heat exchange device and improving the cooling capacity and heat exchange efficiency of the heat exchange device.

[0060] As an optional technical solution of an embodiment of the present application, the second panel is connected to the shell, and the energy storage device includes a blocking member, which is at least partially disposed between the energy storage bin and the second panel.

[0061] In the above technical solution, since the second panel is connected to the shell, there is a gap between the energy storage bin and the second panel, and rainwater, sand and small animals may enter the energy storage bin through the gap. The gap between the energy storage bin and the second panel is blocked by the blocking piece, thereby reducing the risk of rainwater, sand and small animals entering the energy storage bin.

[0062] As an optional technical solution of an embodiment of the present application, the first panel is connected to the energy storage bin.

[0063] In the above technical solution, by connecting the first panel to the energy storage bin, the number of first openings on the energy storage bin can be reduced, and the changes to the energy storage bin can be reduced. The production line for producing the energy storage bin has smaller changes, which is beneficial to reducing the production cost of the energy storage device.

[0064] As an optional technical solution of the embodiment of the present application, the first panel and the second panel are respectively located on two adjacent walls of the energy storage device.

[0065] In the above technical solution, the first panel and the second panel are arranged adjacent to each other, and the first panel and the second panel are located at the corners of the energy storage device, and have high strength. The functional cabinet and the energy storage bin share the first panel and the second panel, which has little effect on the protective effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] The term "plurality" used in the present application refers to two or more (including two).

[0106] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0107] In the prior art, there is an energy storage device. As an important component of the battery energy storage system, the energy storage device has been widely used in the fields of new energy, smart grid, energy-saving technology, etc. Specifically, through the charging and discharging operation of the battery in the energy storage device, it plays the role of peak shaving, improving the quality of power, acting as a backup power source, regulating the frequency and participating in the construction of smart grids. However, the cost of energy storage devices is relatively high at present.

[0108] The energy storage device includes an energy storage bin, a battery and a functional cabinet. The battery and the functional cabinet are both arranged in the energy storage bin. The functional cabinet is used to realize various functions. For example, the functional cabinet can be a control cabinet, a heat exchange device, etc. Taking the functional cabinet as an example of a heat exchange device, the heat exchange device includes a shell and a heat exchange system, and the heat exchange system is arranged in the shell. The shell of the heat exchange device and the energy storage bin both provide protection for the heat exchange system. Since the energy storage bin itself has a high strength, such double protection cannot effectively improve the protection effect, but greatly increases the cost of the energy storage device.

[0109] In view of this, an embodiment of the present application provides an energy storage device, which includes an energy storage bin, a functional cabinet and a panel, wherein the energy storage bin has a first opening. The functional cabinet includes a shell, which is disposed in the energy storage bin, and the shell has a second opening. The panel covers the first opening and the second opening.

[0110] Compared with the solution in the prior art in which the functional cabinet and the energy storage bin are each provided with a panel, the energy storage device uses a panel to cover the first opening of the energy storage bin and the second opening of the shell, that is, the functional cabinet and the energy storage bin share a panel, which reduces the number of panels and reduces the production cost of the energy storage device.

[0111] The technical solution described in the embodiments of the present application is applicable to energy storage devices and can reduce the manufacturing cost of energy storage devices.

[0112] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of an energy storage device 10 provided in some embodiments of the present application. Figure 2 An exploded view of an energy storage device 10 provided in some embodiments of the present application. The present application provides an energy storage device 10, which includes an energy storage bin 11, a functional cabinet 12, and a panel 13. The energy storage bin 11 has a first opening 111. The functional cabinet 12 includes a shell 121, which is disposed in the energy storage bin 11, and the shell 121 has a second opening 122. The panel 13 covers the first opening 111 and the second opening 122.

[0113] The energy storage device 10 is an important component of the battery energy storage system. The energy storage device 10 plays the role of shaving peaks and filling valleys, improving power quality, serving as a backup power source, and regulating frequency to participate in the construction of smart grids through the charging and discharging operations of the batteries in the energy storage device 10.

[0114] The energy storage bin 11 is the outer shell of the energy storage device 10. Most of the components of the energy storage device 10, such as batteries, are arranged in the energy storage bin 11 and are protected by the energy storage bin 11. The energy storage bin 11 can be a container, a cabinet, and the like.

[0115] The functional cabinet 12 is a device that is arranged in the energy storage bin 11 to realize various functions. For example, the functional cabinet 12 can be a control cabinet to realize the electrical control of the energy storage device 10. For another example, the functional cabinet 12 can be a heat exchange device, which is used to provide a heat exchange medium to the battery so as to realize the thermal management of the battery. The heat exchange device can provide a refrigerant to the battery to reduce or increase the temperature of the battery. Generally speaking, the heat exchange device provides water as a refrigerant to the battery. The heat exchange device includes a shell 121, and the shell 121 is arranged in the energy storage bin 11, and a heat exchange system is arranged in the shell 121.

[0116] The panel 13 is a plate structure for covering the first opening 111 of the energy storage bin 11 and the second opening 122 of the housing 121. The panel 13 may completely cover the first opening 111 and the second opening 122, or may cover a portion of the first opening 111 and a portion of the second opening 122.

[0117] In this embodiment, the panel 13 covers the first opening 111 and the second opening 122, that is, the shell 121 and the energy storage bin 11 share the panel 13. The panel 13 contributes to defining the internal space of the energy storage bin 11 and the internal space of the shell 121.

[0118] Compared with the solution in the prior art in which the functional cabinet 12 and the energy storage bin 11 are each provided with a panel, the energy storage device 10 covers the first opening 111 of the energy storage bin 11 and the second opening 122 of the shell 121 with a panel 13, that is, the functional cabinet 12 and the energy storage bin 11 share a panel 13, which reduces the number of panels 13 and reduces the production cost of the energy storage device 10.

In this way, the sealing plate 1422 can be mostly or even completely set in the gap between the energy storage bin 11 and the panel 13, thereby achieving sealing of the gap, and the sealing effect is better.

[0139] In some embodiments, the first connecting plate 1412 is welded to the energy storage bin 11; and / or the second connecting plate 1413 and the third connecting plate 1421 are detachably connected.

[0140] The first connecting plate 1412 can be welded to the energy storage bin 11 so that the first connecting plate 1412 and the energy storage bin 11 have a higher connection strength.

[0141] "Removable connection" refers to a connection method in which the connecting member and the connected member are not damaged after thousands of repeated assembly and disassembly, and the original connection quality can be maintained. For example, the second connecting plate 1413 can be bolted to the third connecting plate 1421, and the second connecting plate 1413 can also be snapped to the third connecting plate 1421.

[0153] Please refer to Figure 7 and Figure 8 In some embodiments, the energy storage device 10 includes a seal 143 , and the seal 143 is disposed on the sealing portion 142 .

[0154] The seal 143 is a structure capable of achieving a sealing effect, such as a sealant, a sealing gasket or a sealing sheet, etc. The seal 143 is connected to the blocking portion 142. After installation, the seal 143 is arranged between the blocking portion 142 and the panel 13 (or the energy storage bin 11), thereby achieving a sealing effect.

[0155] By providing a seal 143 on the sealing portion 142 , the sealing performance of the gap between the energy storage bin 11 and the panel 13 is improved, and the risk of rainwater and sand and gravel entering the energy storage bin 11 is further reduced.

[0156] Optionally, the sealing member 143 is foam, and the foam is fixed to the blocking portion 142 .

[0157] Please refer to Figure 7 and Figure 8 ,exist Figure 7 and Figure 8 In the illustrated embodiment, the sealing member 143 is connected to a side of the blocking portion 142 that is away from the connecting portion 141 .

[0158] Please refer to Fig. 9 and Fig.10 , Fig. 9 This is a schematic structural diagram of the blocking member 14 provided in some further embodiments of the present application. Fig.10 This is a top view of a blocking member 14 provided in some other embodiments of the present application. Fig. 9 and Fig.10 In the illustrated embodiment, the sealing member 143 is connected to a side of the blocking portion 142 that is away from the third connecting plate 1421 .

[0159] Please refer to Fig.11 , Fig.11 The following is a schematic diagram of the installation of the blocking member 14 provided for some further embodiments of the present application. When installing the blocking member 14, the first connecting plate 1412 can be welded to the energy storage bin 11 first, and then the third connecting plate 1421 can be connected to the second connecting plate 1413. At this time, the position of the third connecting plate 1421 needs to be adjusted so that the sealing member 143 can abut against the panel 13, thereby sealing between the blocking plate 1422 and the panel 13. After the position is adjusted, the locking member can be locked. During installation, the third connecting plate 1421 can be connected to the side of the second connecting plate 1413 that is away from the inside of the energy storage bin 11. In this way, the third connecting plate 1421 can block the strip hole 1411, making it difficult for rainwater, sand and gravel, and small animals to enter the energy storage bin 11 from the strip hole 1411.

[0160] Please refer to Fig.12 , Fig.12 The schematic diagram of the structure of the blocking member 14 provided in some embodiments of the present application. In some other embodiments, the sealing member 143 at least covers the portion of the blocking portion 142 located between the energy storage bin 11 and the panel 13 .

[0161] The seal 143 may only cover the portion of the sealing portion 142 located between the energy storage bin 11 and the panel 13 , or the seal 143 may completely cover the sealing portion 142 .

[0162] By making the seal 143 at least partially cover the portion of the sealing part 142 located between the energy storage bin 11 and the panel 13, the seal 143 can not only seal the gap between the sealing part 142 and the energy storage bin 11, but also seal the gap between the sealing part 142 and the panel 13, thereby further reducing the risk of rainwater and sand and gravel entering the energy storage bin 11.

[0163] Optionally, in some embodiments, the seal 143 includes a covering body 1431 and an airbag 1432, wherein the covering body 1431 covers at least a portion of the blocking portion 142 between the energy storage bin 11 and the panel 13.

[0164] The covering body 1431 is the portion of the seal 143 that covers the blocking portion 142. The covering body 1431 may only cover the portion of the blocking portion 142 between the energy storage bin 11 and the panel 13, or the covering body 1431 may completely cover the blocking portion 142.

[0165] The airbag 1432 is a sac body for storing gas, and the airbag 1432 is connected to the covering body 1431. Due to the presence of gas in the airbag 1432, the outer surface of the airbag 1432 can be pressed against the energy storage bin 11 and the panel 13, thereby achieving sealing.

[0166] When the sealing portion 142 enters between the energy storage bin 11 and the panel 13, the gas in the airbag 1432 is subjected to a large pressure and is gradually released until the sealing portion 142 reaches a specified position and the airbag 1432 stops releasing gas. The airbag 1432 and the energy storage bin 11, as well as the airbag 1432 and the panel 13, have a large fitting area and can maintain the sealing of the gap between the energy storage bin 11 and the panel 13 under the action of the internal gas.

[0178] In some embodiments, a sealing member 143 is disposed on the blocking member 14 , and the sealing member 143 is at least partially sealed between the energy storage bin 11 and the blocking member 14 . And / or the sealing member 143 is at least partially sealed between the panel 13 and the blocking member 14 .

[0179] The seal 143 may be disposed only between the energy storage bin 11 and the blocking member 14 , or only between the panel 13 and the blocking member 14 , or both.

[0180] The seal 143 is provided to seal the gap between the energy storage bin 11 and the blocking member 14 and / or the gap between the sealing panel 13 and the blocking member 14, thereby reducing the risk of rainwater, sand and gravel, and small animals entering the energy storage bin 11.

[0181] Please refer to Fig. 20 and Fig.21 , Fig. 20 A schematic diagram of the structure of an energy storage device 10 provided in some further embodiments of the present application. Fig.21Exploded view of an energy storage device 10 provided in some further embodiments of the present application. In some further embodiments, the energy storage device 10 includes a plurality of functional cabinets 12 and a plurality of panels 13. Each functional cabinet 12 includes a shell 121, which is disposed in the energy storage bin 11, and each shell 121 has a second opening 122. Each panel 13 covers the first opening 111 and at least one second opening 122.

[0182] It should be noted that the functions of the multiple functional cabinets 12 may be the same or different. For example, the multiple functional cabinets 12 may all be heat exchange devices. For another example, some functional cabinets 12 are heat exchange devices, and other functional cabinets 12 are control cabinets.

[0183] In an embodiment where the energy storage device 10 includes a plurality of functional cabinets 12 , the plurality of functional cabinets 12 may be arranged side by side.

In some embodiments, a shielding member 132 is disposed on the panel 13 , and the shielding member 132 is used to shield the first air outlet 131 .

[0190] The shielding member 132 is a component for shielding the first air outlet 131. The shielding member 132 is connected to the panel 13, and can prevent foreign matter or liquid from entering the first air outlet 131, but can allow air to pass through the first air outlet 131, thereby achieving air intake.

[0191] By providing the shielding member 132 to shield the first air outlet 131 , the risk of foreign matter or liquid entering the heat exchange device through the first air outlet 131 is reduced.

[0192] Please refer to Fig.24 , Fig.25 and Fig.26 In some embodiments, the shielding member 132 is formed with a fluid channel 1321 , one end of the fluid channel 1321 is connected to the first air outlet 131 , and the other end of the fluid channel 1321 extends to the bottom of the shielding member 132 .

[0193] The shielding member 132 is protruding from the panel 13, and a fluid channel 1321 is formed on the shielding member 132. The first air outlet 131 is connected to one end of the fluid channel 1321, and the other end of the fluid channel 1321 forms an inlet at the bottom wall of the shielding member 132. In this way, foreign impurities and liquid will slide downward through the shielding member 132 under the action of gravity, and it is not easy to enter the fluid channel 1321 from the inlet at the bottom of the shielding member 132, and it is even more difficult to flow to the first air outlet 131 through the fluid channel 1321.

[0194] Air enters the fluid channel 1321 from the bottom of the shielding member 132, and enters the heat exchange device through the first air port 131, thereby achieving air intake. Since the other end of the fluid channel 1321 extends to the bottom of the shielding member 132, it is difficult for foreign impurities or liquids to enter the fluid channel 1321 from the bottom of the shielding member 132, and it is even more difficult to pass through the fluid channel 1321 to reach the first air port 131, thereby reducing the risk of foreign impurities or liquids entering the heat exchange device, which is conducive to the stable operation of the heat exchange device, improving the heat exchange efficiency of the heat exchange device, and improving the life of the heat exchange device.

[0195] Please refer to Fig.24 , Fig.25 and Fig.26 In some embodiments, a plurality of first air outlets 131 are provided on the panel 13 , and each first air outlet 131 is provided with a shielding member 132 .

[0196] The panel 13 may be provided with two first air vents 131, three first air vents 131, four first air vents 131, or more than four first air vents 131. The shielding member 132 corresponds to the first air vent 131 one by one, that is, one shielding member 132 is provided for each first air vent 131, so as to reduce the risk of foreign matter or liquid entering the heat exchange device.

[0197] By providing a plurality of first air vents 131 on the panel 13, the heat exchange device can directly take in air from the plurality of first air vents 131, and the air intake of the heat exchange device is less blocked and the resistance is reduced, which is conducive to increasing the air volume of the heat exchange device and improving the cooling capacity and heat exchange efficiency of the heat exchange device. Each first air vent 131 is provided with a shielding member 132 to reduce the risk of foreign impurities or liquids entering the heat exchange device from the first air vent 131.

[0198] Please refer to Fig.24 , Fig.25 and Fig.26 In some embodiments, a plurality of first air outlets 131 are distributed in an array.

[0199] The plurality of first air outlets 131 may be distributed in a rectangular array or a circular array.

[0200] By arranging the plurality of first air outlets 131 in an array, the mutual influence of the plurality of first air outlets 131 is reduced, which is beneficial to air intake.

[0201] Please refer to Fig. 27 , Fig. 27 The panel 13 and the filter 15 are connected in some embodiments of the present application. The panel 13 is provided with the filter 15, and the filter 15 is used to filter impurities in the gas passing through the first air port 131.

[0202] The filter element 15 is a component for filtering out impurities in the gas passing through the first air port 131. The filter element 15 may be a filter mesh. The filter element 15 may also include a graphite filter layer or the like.

[0203] By setting the filter 15, impurities in the gas passing through the first air port 131 are filtered out, reducing the risk of impurities entering the heat exchange device, which is beneficial to the stable operation of the heat exchange device, improving the heat exchange efficiency of the heat exchange device, and increasing the life of the heat exchange device.

[0204] In some embodiments, the filter 15 is detachably connected to the panel 13 .

[0205] By detachably connecting the filter element 15 to the panel 13 , the filter element 15 can be easily removed for cleaning, or when the filter element 15 is damaged, the filter element 15 can be removed and replaced.

[0206] Please refer to Fig. 27 In some embodiments, the panel 13 is provided with a receiving space 133, and the filter 15 is at least partially received in the receiving space 133. The receiving space 133 is formed with an insertion port 1331 on the outer surface of the panel 13 for the filter 15 to enter or exit the receiving space 133.

[0207] The filter element 15 can be inserted into or withdrawn from the accommodating space 133 through the insertion opening 1331 to achieve a detachable connection between the filter element 15 and the panel 13 .

[0208] The accommodating space 133 may be a slot opened on the panel 13 , and two ends of the filter element 15 are respectively matched with the two slots to achieve the plug-in connection between the filter element 15 and the panel 13 .

[0209] The filter 15 is detachably connected to the panel 13 by plugging. When installing the filter 15, it is only necessary to insert the filter 15 from the socket 1331 into the receiving space 133. When removing the filter 15, it is only necessary to pull the filter 15 out of the receiving space 133 from the socket 1331, which is simple and convenient.

[0210] Please refer to Fig. 27 In some embodiments, the socket 1331 is located at the top of the panel 13 .

[0211] “The socket 1331 is located at the top of the panel 13 ” means that the socket 1331 is located at the upper end of the panel 13 .

[0212] The socket 1331 is disposed at the top of the panel 13 , and the filter 15 is at least partially accommodated in the accommodation space 133 under the action of gravity, and is not easily separated from the accommodation space 133 from the socket 1331 .

[0213] Please refer to Fig.28 and Fig.29 , Fig.28 Schematic diagram of the connection between the panel 13 and the filter element 15 provided in some other embodiments of the present application. Fig.29 for Fig.28 In other embodiments, the filter element 15 is disposed on a side of the panel 13 facing the interior of the housing 121 .

[0214] By arranging the filter element 15 on the side of the panel 13 facing the interior of the shell 121 , the filter element 15 is less likely to be damaged and less likely to be dirty than arranging the filter element 15 on the side of the panel 13 facing away from the interior of the shell 121 .

[0215] In some embodiments, the panel 13 is provided with a snap-fitting member 134 , and the snap-fitting member 134 is used to lock or unlock the panel 13 and the filter element 15 .

[0216] The clamping member 134 may be a buckle, and the panel 13 and the filter element 15 may be locked or released by flipping the buckle.

[0217] When the clamping member 134 locks the panel 13 and the filter 15, the relative position of the filter 15 and the panel 13 is limited, and the filter 15 cannot be separated from the panel 13. When the clamping member 134 unlocks the panel 13 and the filter 15, the filter 15 can be separated from the panel 13, thereby achieving disassembly.

[0218] In some embodiments, the panel 13 is connected to the energy storage bin 11 .

[0219] The panel 13 may be detachably connected to the energy storage bin 11 , or may be integrally formed with the energy storage bin 11 .

[0220] By connecting the panel 13 to the energy storage bin 11 , only the second opening 122 can be set on the shell 121 without changing the energy storage bin 11 , and the production line for producing the energy storage bin 11 does not need to be changed, which is beneficial to reducing the production cost of the energy storage device 10 .

[0221] Please refer to Fig.30 and Fig.31 , Fig.30 Schematic diagram of the structure of the energy storage device 10 provided in some other embodiments of the present application. Fig.31 Exploded diagram of energy storage device 10 provided in some other embodiments of the present application. In some other embodiments, energy storage bin 11 includes a plurality of first openings 111, and housing 121 includes a plurality of second openings 122. Energy storage device 10 includes a plurality of panels 13, each panel 13 covers at least one first opening 111 and at least one second opening 122.

[0222] A panel 13 can cover a first opening 111 and a second opening 122. A panel 13 can also cover more than two first openings 111 and one second opening 122. A panel 13 can also cover a first opening 111 and more than two second openings 122. A panel 13 can also cover more than two first openings 111 and more than two second openings 122.

[0223] “The energy storage device 10 includes a plurality of panels 13 , and each panel 13 covers at least one first opening 111 and at least one second opening 122 ”, that is, the energy storage bin 11 and the shell 121 share a plurality of panels 13 .

[0224] The functional cabinet 12 and the energy storage bin 11 share multiple panels 13 at multiple locations, which reduces the number of panels 13 and reduces the production cost of the energy storage device 10 .

[0225] Please refer to Fig.30 and Fig.31 In some embodiments, the plurality of panels 13 include a first panel 135 and a second panel 136. The functional cabinet 12 is a heat exchange device. The first panel 135 is provided with a first air port 131, and the first air port 131 is used to supply air to the heat exchange device. The second panel 136 is provided with a second air port 1361, and the second air port 1361 is used to exhaust air from the heat exchange device.

[0226] The second air vent 1361 is a ventilation structure provided on the second panel 136. The first air vent 131 is an air inlet for supplying air to the heat exchange device. The second air vent 1361 is an air outlet for discharging air from the heat exchange device.

[0227] The heat exchange device and the energy storage bin 11 of the energy storage device 10 share the first panel 135 and the second panel 136 (equivalent to sharing the air inlet panel and / or the air outlet panel). The first panel 135 and the second panel 136 can still provide a good protective effect on the internal components of the shell 121, and will not cause a significant weakening of the protective effect. Since the first panel 135 and the second panel 136 are shared, the number of panels 13 is reduced, and the production cost of the energy storage device 10 can be reduced. The first panel 135 is provided with a first air port 131, and the heat exchange device can directly take in or exhaust air from the first air port 131. Since the number of panels 13 is reduced, the air intake or exhaust of the heat exchange device is less blocked, and the resistance is reduced, which is conducive to increasing the air volume of the heat exchange device and improving the cooling capacity and heat exchange efficiency of the heat exchange device.

[0228] In some embodiments, the second panel 136 is connected to the housing 121 . The energy storage device 10 includes a blocking member 14 , which is at least partially disposed between the energy storage bin 11 and the second panel 136 .

[0229] Since the second panel 136 is connected to the housing 121, there is a gap between the energy storage bin 11 and the second panel 136, and rainwater, sand and small animals may enter the energy storage bin 11 through the gap. The gap between the energy storage bin 11 and the second panel 136 is blocked by the blocking member 14, thereby reducing the risk of rainwater, sand and small animals entering the energy storage bin 11.

[0230] Please refer to Fig.30 and Fig.31 In some embodiments, the first panel 135 is connected to the energy storage bin 11 .

[0231] By connecting the first panel 135 to the energy storage bin 11, the number of first openings 111 on the energy storage bin 11 can be reduced, and changes to the energy storage bin 11 can be reduced. The production line for producing the energy storage bin 11 has smaller changes, which is beneficial to reducing the production cost of the energy storage device 10.

[0232] Please refer to Fig.30 and Fig.31 In some embodiments, the first panel 135 and the second panel 136 are respectively located on two adjacent walls of the energy storage device 10 .

[0233] The energy storage device 10 may include a plurality of walls, and the first panel 135 and the second panel 136 are two adjacently disposed walls of the energy storage device 10 .

[0234] The first panel 135 and the second panel 136 are arranged adjacent to each other. The first panel 135 and the second panel 136 are located at the corners of the energy storage device 10 and have high strength. The functional cabinet 12 and the energy storage bin 11 share the first panel 135 and the second panel 136, which has little effect on the protective effect.

[0235] According to some embodiments of this application, please refer to Figure 1 to Figure 31 .

[0236] The embodiment of the present application provides an energy storage device 10, which includes an energy storage bin 11, a functional cabinet 12 and a panel 13. The energy storage bin 11 has a first opening 111. The functional cabinet 12 includes a shell 121, which is arranged in the energy storage bin 11, and the shell 121 has a second opening 122. The panel 13 covers the first opening 111 and the second opening 122. Compared with the solution in the prior art in which the functional cabinet 12 and the energy storage bin 11 are each provided with a panel, the energy storage device 10 covers the first opening 111 of the energy storage bin 11 and the second opening 122 of the shell 121 with a panel 13, that is, the functional cabinet 12 and the energy storage bin 11 share a panel 13, which reduces the number of panels 13 and reduces the production cost of the energy storage device 10.

[0237] The panel 13 is connected to the shell 121. The energy storage device 10 includes a blocking member 14, which is at least partially disposed between the energy storage bin 11 and the panel 13. By connecting the panel 13 to the shell 121, it is possible to only set the first opening 111 on the energy storage bin 11 without changing the functional cabinet 12, and the production line for producing the functional cabinet 12 does not need to be changed, which is beneficial to reducing the production cost of the energy storage device 10. There is a gap between the energy storage bin 11 and the panel 13, and rainwater, sand and gravel, and small animals may enter the energy storage bin 11 through the gap. The gap between the energy storage bin 11 and the panel 13 is blocked by the blocking member 14, thereby reducing the risk of rainwater, sand and gravel, and small animals entering the energy storage bin 11.

[0238] The sealing member 14 is provided with a sealing member 143, and the sealing member 143 is at least partially sealed between the energy storage bin 11 and the sealing member 14; and / or the sealing member 143 is at least partially sealed between the panel 13 and the sealing member 14. The sealing member 143 is provided to seal the gap between the energy storage bin 11 and the sealing member 14 and / or the gap between the panel 13 and the sealing member 14, thereby reducing the risk of rainwater, sand and gravel, and small animals entering the energy storage bin 11.

[0239] The functional cabinet 12 is a heat exchange device, and a first air port 131 is provided on the panel 13. The first air port 131 is used to supply air to or exhaust air from the heat exchange device. The heat exchange device can provide a heat exchange medium to the battery so as to achieve thermal management of the battery. By providing the first air port 131 on the panel 13, the heat exchange device can directly take in or exhaust air from the first air port 131. Since the number of panels 13 is reduced, the obstruction of the heat exchange device inlet or exhaust air is reduced, and the resistance is reduced, which is conducive to increasing the air volume of the heat exchange device and improving the cooling capacity and heat exchange efficiency of the heat exchange device.

[0240] A shielding member 132 is provided on the panel 13. The shielding member 132 forms a fluid channel 1321. One end of the fluid channel 1321 is connected to the first air outlet 131, and the other end of the fluid channel 1321 extends to the bottom of the shielding member 132. Air enters the fluid channel 1321 from the bottom of the shielding member 132, and enters the heat exchange device through the first air outlet 131, thereby achieving air intake. Since the other end of the fluid channel 1321 extends to the bottom of the shielding member 132, it is difficult for foreign impurities or liquids to enter the fluid channel 1321 from the bottom of the shielding member 132, and it is even more difficult to reach the first air outlet 131 through the fluid channel 1321, thereby reducing the risk of foreign impurities or liquids entering the heat exchange device, which is conducive to the stable operation of the heat exchange device, improving the heat exchange efficiency of the heat exchange device, and improving the life of the heat exchange device.

[0241] The panel 13 is provided with a filter 15, and the filter 15 is used to filter impurities in the gas passing through the first air port 131. By providing the filter 15, impurities in the gas passing through the first air port 131 are filtered out, reducing the risk of impurities entering the heat exchange device, which is conducive to the stable operation of the heat exchange device, improving the heat exchange efficiency of the heat exchange device, and improving the life of the heat exchange device.

[0242] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
