Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component.

[0038] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this application includes any and all combinations of one or more of the relevant listed items.

[0039] The following describes some embodiments disclosed in this application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0040] With reference to FIG. 1 and FIG. 2 , the present application discloses an energy storage device, including an energy storage cabinet 100 and a battery pack 200 , wherein the battery pack 200 is accommodated in the energy storage cabinet 100 .

[0041] The energy storage device is also provided with a cooling system 300, which includes a cooling pipe and an air conditioner. The air conditioner is connected to the cooling pipe to cool or heat the circulating water in the cooling pipe. The cooling pipe is connected to the cooling assembly of the battery pack 200.

[0042] There can be multiple or one battery pack 200, without limitation. The battery pack 200 in the energy storage cabinet 100 can provide energy storage, load balancing, backup power, and energy conservation and emission reduction. The battery pack 200 is sensitive to humidity. Excessive humidity can cause internal battery short circuits, electrolyte leakage, and even fire in severe cases. A dehumidifier 10 should be placed inside the energy storage cabinet 100 to reduce humidity and keep the batteries dry and safe.

[0043] The present application discloses an energy storage cabinet 100, comprising a cabinet body 20 and a dehumidifier 10. The cabinet body 20 encloses a sealed space, and the dehumidifier 10 is accommodated in the sealed space.

[0044] There can be one or more dehumidifiers 10 without limitation.

[0045] Energy storage cabinet 100 also includes a cabinet door 21. When closed, cabinet door 21 seals cabinet body 20 to form a sealed space. Cabinet door 21 can also be opened during installation, maintenance, and other processes for ease of operation. Energy storage cabinet 100 also includes a seal 22, which is disposed on cabinet door 21 and is suitable for enhancing the sealing performance of energy storage cabinet 100.

[0046] The enclosed space of the energy storage cabinet 100 can reduce air flow inside and outside the cabinet 100, reducing the impact of external conditions on the internal temperature and humidity of the cabinet 100. Under normal circumstances, the internal humidity of the enclosed energy storage cabinet 100 does not change significantly. However, in actual transportation, installation, maintenance, and replacement of battery packs 200, the cabinet door 21 must be opened, which may cause the internal humidity to exceed the set operating threshold. Therefore, the enclosed energy storage cabinet 100 still needs dehumidification function.

[0047] The energy storage cabinet 100 is made of a material with certain structural strength and corrosion resistance. The material can be divided into two categories: metal and non-metal, specifically aluminum alloy, nickel steel plate, stainless steel, fiberglass and plastic, etc., without limitation.

[0048] Referring to Figure 1, in one embodiment, the energy storage cabinet 100 further includes a partition 30. The partition 30 can be multiple, and the partition 30 divides the cabinet body 20 into multiple spaces. The partition 30 can also support the battery pack 200, so that the energy storage cabinet 100 can accommodate multiple battery packs 200, thereby improving the energy density of the energy storage cabinet 100.

[0049] The partition 30 and the cabinet body 20 may be an integral structure, i.e., the partition 30 and the cabinet body 20 are an integral structure manufactured by an integral molding process, which may be stamping, casting, etc., without limitation. The partition 30 and the cabinet body 20 may also be a separate structure, and the partition 30 and the cabinet body 20 may be connected and fixed by welding, bonding, clamping, screwing, etc.

[0050] In one embodiment, the dehumidifier 10 is detachably connected to the cabinet 20. The connection between the dehumidifier 10 and the cabinet 20 can be threaded, snap-fit, or adhesively bonded, without limitation. The energy storage cabinet 100 and dehumidifier 10 feature a split design and detachable connection, facilitating production, installation, and commissioning of the energy storage cabinet 100. This also facilitates subsequent troubleshooting and routine maintenance. If the dehumidifier 10 malfunctions and stops functioning properly, simply open the cabinet door 21 of the energy storage cabinet 100 and replace it with the standalone dehumidifier 10, simplifying operation.

[0051] In one embodiment, the energy storage cabinet 100 is further provided with a camera. The camera monitors the real-time image inside the cabinet 20, which can make a more reasonable judgment on the health condition inside the cabinet 20, and is conducive to the safe use, evaluation and maintenance of the energy storage cabinet 100.

[0052] With reference to FIG3 , the present application discloses a dehumidifier 10 suitable for installation within a cabinet 20 of an energy storage cabinet 100. Dehumidifier 10 includes a detection component, a control component, and a dehumidification assembly 11. The detection component is suitable for detecting the air humidity within the energy storage cabinet 100. The control component is electrically connected to the detection component. When the air humidity detected by the detection component is greater than or equal to 40% RH, the control component issues a first control instruction. Furthermore, the dehumidification assembly 11 is electrically connected to the control component and operates according to the first control instruction to condense moisture in the air within the energy storage cabinet 100 into dew.

[0053] When the air humidity detected by the detection component is less than 40% RH, the control component issues a second control instruction and the dehumidification component 11 stops working.

[0054] The detection component can be a sensor, a capacitor, a resistor, etc. The control component can be an integrated circuit, a chip, etc.

[0055] The dehumidifier 10 disclosed in this application is provided with a detection component, a control component, and a dehumidification assembly 11. When the detection component detects that the air humidity in the energy storage cabinet 100 is greater than or equal to 40% RH, the control component issues a first control instruction to activate the dehumidification assembly 11, ensuring that the dehumidifier 10 starts dehumidification in advance when condensation conditions are about to be reached in the energy storage cabinet 100. This dehumidifier 10 changes the passive condensation prevention mode to an active condensation guidance mode, which can effectively prevent safety hazards such as equipment aging, material mildew or corrosion, electronic device breakdown, and metal structural corrosion in the energy storage cabinet 100, thereby extending the operating time of the energy storage cabinet 100.

[0056] Referring to Figure 3, in one embodiment, the dehumidification component 11 includes a cold-end radiator 111, a semiconductor refrigeration plate 112 and a hot-end radiator 113. The semiconductor refrigeration plate 112 has a cold surface and a hot surface arranged in opposite directions. The cold-end radiator 111 is connected to the cold surface, and the hot-end radiator 113 is connected to the hot surface.

[0057] Semiconductor refrigeration chip 112 is primarily made of silicon-based semiconductor materials, germanium-based semiconductor materials, selenium-based semiconductor materials, and glass-ceramic semiconductor materials. Semiconductor refrigeration chip 112 utilizes the Peltier effect of semiconductors. When current flows through a loop composed of different conductors, in addition to generating irreversible Joule heating, heat absorption and heat release occur at the joints of the different conductors depending on the direction of the current flow.

[0058] The hot end radiator 113 is an important component for dissipating the heat of the hot end. The materials of the hot end radiator 113 include copper, aluminum, stainless steel, etc. The hot end radiator 113 can be fin type, heat pipe type, flat plate type, etc.

[0059] The cold end heat sink 111 is connected to the cold surface to increase the temperature difference between the cold surface and the hot surface of the semiconductor refrigeration plate 112, thereby facilitating the generation of condensation.

[0060] Thermal insulation foam 114 is also located between the semiconductor cooling plate 112 and the hot-end heat sink 113. Specifically, it can be made of air insulation foam, rock wool insulation foam, glass wool insulation foam, ceramic fiber insulation foam, etc. Thermal insulation foam 114 is primarily used to reduce the impact of heat generated by the hot surface on electronic components such as the circuit board 17 within the dehumidifier 10. A groove is defined in thermal insulation foam 114, into which the hot surface of the semiconductor cooling plate 112 extends, connecting to the hot-end heat sink 113, which dissipates heat.

[0061] The cold-end radiator 111 , the semiconductor cooling plate 112 and the hot-end radiator 113 may be connected by bonding, clamping, screwing or the like.

[0062] By utilizing the Peltier effect of semiconductors to achieve a temperature difference between the cold and hot surfaces, the fan 13 actively draws humid air from the enclosed space within the energy storage cabinet 100 into the dehumidifier 10. After passing through the dehumidification component 11, the water vapor is cooled and condensed into water. This achieves a transition from passive condensation prevention to active condensation guidance, helping to maintain the air humidity within the energy storage cabinet 100 at 40% RH, thereby improving the service life and safety of components such as the battery pack 200.

[0063] Referring to Figure 3 , in one embodiment, the dehumidifier 10 further includes a housing 12, which encloses a receiving cavity, and the dehumidification assembly 11 is received within the receiving cavity. The housing 12 includes a top plate 121 and a bottom plate 122 disposed opposite each other. The dehumidification assembly 11 is disposed on a side of the bottom plate 122 relative to the detection element, and air flows from the dehumidification assembly 11 toward the detection element.

[0064] The housing 12 may be a one-piece structure, i.e., a one-piece structure made by an one-piece molding process, wherein the one-piece molding process may be stamping, casting, etc., without limitation. The housing 12 may also be a split structure, connected and fixed by welding, bonding, clamping, screwing, etc.

[0065] In one embodiment, the detection component and the control component are both arranged on the outer wall of the shell 12, or at least one of the detection component and the control component is accommodated in the accommodating cavity, that is, the detection component and the control component are both accommodated in the accommodating cavity, or the detection component is accommodated in the accommodating cavity and the control component is arranged on the outer wall of the shell 12, or the control component is accommodated in the accommodating cavity and the detection component is arranged on the outer wall of the shell 12.

[0066] The detection element can be disposed within the receiving chamber or outside the receiving chamber, without limitation. The detection element can accurately and in real time collect actual temperature and humidity changes within the dehumidifier 10 or the energy storage cabinet 100, ensuring that the dehumidifier 10 starts dehumidification in advance when condensation conditions are about to be reached within the energy storage cabinet 100. This helps to ensure the humidity stability of the working environment of the battery pack 200 and extend the service life of the battery pack 200.

[0067] With reference to FIG3 , in one embodiment, the dehumidifier 10 further includes a fan 13 . The fan 13 is fixedly connected to the top plate 121 . The fan 13 is also electrically connected to the control component. The fan 13 is suitable for accelerating the flow of air.

[0068] There can be multiple fans 13, which are arranged at intervals on the top plate 121. When the control component issues a first control instruction, the fan 13 works, and when it issues a second control instruction, the fan 13 does not work.

[0069] When the air humidity detected by the detection component is greater than or equal to 40% RH, the control component issues a first control instruction and the fan 13 works; when the air humidity detected by the detection component is less than 40% RH, the control component issues a second control instruction and the fan 13 stops working.

[0070] The fan 13 can be an axial flow fan 13. The axial flow fan 13 has low wind pressure, large air volume, good heat dissipation effect, and low noise, and is suitable for heat dissipation over a large area. At the same time, the fan 13 can accelerate the air flow in the dehumidifier 10, so that the dehumidifier 10 can complete the dehumidification of the humid air as quickly as possible.

[0071] Referring to Figure 3, in one embodiment, the dehumidifier 10 also includes a funnel 14 and a drain pipe 15. The funnel 14 is fixedly connected to the bottom plate 122 and is directly opposite to the semiconductor refrigeration plate 112. The funnel 14 is suitable for collecting dew dripping from the semiconductor refrigeration plate 112. The drain pipe 15 is connected to the funnel 14 and is suitable for extending to the outside of the energy storage cabinet 100.

[0072] The funnel 14 and the bottom plate 122 can be connected by screw connection, clamping connection, bonding, etc., without limitation. Optionally, a mounting hole 1221 is opened on the bottom plate 122, and the drain pipe 15 passes through the mounting hole 1221 and extends to the outside of the dehumidifier 10.

[0073] Dehumidifier 10 utilizes semiconductor cooling fins 112, which, when energized, create a temperature difference between the top and bottom surfaces. This actively draws humid air from the enclosed space within energy storage cabinet 100 into dehumidifier 10 under the action of fan 13. The moisture passes through dehumidifier assembly 11, cools down, condenses, and condenses into water. Under the influence of natural gravity, the water drips into funnel 14 within dehumidifier 10 and is then discharged from dehumidifier 10 and energy storage cabinet 100 through drain pipe 15. The dehumidifier 10 disclosed in this application is compact, occupying minimal space within energy storage cabinet 100. It operates only when the humidity within the cabinet is detected to be greater than or equal to 40% RH, achieving both energy conservation and environmental protection, as well as effective dehumidification.

[0074] With reference to FIG. 3 , in one embodiment, a first air inlet 1222 is provided on the bottom plate 122 . The first air inlet 1222 is disposed on the bottom plate 122 and corresponds to the hot-end heat sink 113 .

[0075] The first air inlet 1222 can be a plurality of through holes arranged at intervals, or can be a single through hole. The shape of the through hole can be strip, circular, rectangular, etc., without limitation.

[0076] The provision of the first air inlet 1222 can improve the heat dissipation effect of the hot end radiator 113 , which is beneficial to increasing the service life of the semiconductor cooling plate 112 .

[0077] In one embodiment, the shell 12 further includes a first side plate 123 , which connects the bottom plate 122 and the top plate 121 . The cold end radiator 111 is located on the side of the semiconductor refrigeration plate 112 facing the first side plate 123 . The first side plate 123 is provided with a second air inlet 1231 .

[0078] The second air inlet 1231 can be a plurality of through holes arranged at intervals, or can be a single through hole. The shape of the through hole can be strip, circular, rectangular, etc., without limitation.

[0079] A second air inlet 1231 is provided for absorbing the air in the energy storage cabinet 100 into the dehumidifier 10. On the one hand, the detection component can detect the humidity of the air. On the other hand, when the fan 13 is working, the air in the energy storage cabinet 100 enters the dehumidifier 10 through the second air inlet 1231 for dehumidification.

[0080] The housing 12 further includes a second side panel 124 disposed opposite the first side panel 123, and the second side panel 124 is fixedly connected to the cabinet 20. The second side panel 124 can be fixedly connected to the cabinet 20 by a detachable connection such as screwing, clamping, or bonding, which facilitates subsequent maintenance and replacement.

[0081] With reference to FIG. 3 , in one embodiment, the dehumidifier 10 further includes a first foam 16 . The first foam 16 is disposed between the first side plate 123 and the cold end radiator 111 and is disposed corresponding to the second air inlet 1231 .

[0082] The first foam 16 can be silicone foam, polyurethane foam, EPDM sound-absorbing cotton, EPE pearl cotton, PVC foam, PE (polyethylene) foam, PP (polypropylene) foam, CR (chloroprene rubber) foam, EVA (ethylene and vinyl acetate) foam, XPE foam, IXPE foam, acrylic foam, etc., without limitation.

[0083] The shape of the first foam 16 corresponds to the shape of the second air inlet 1231 .

[0084] Providing the first foam 16 at the second air inlet 1231 can prevent impurities such as dust in the energy storage cabinet 100 from entering the dehumidifier 10 and affecting the service life of the dehumidifier 10 .

[0085] In one embodiment, the dehumidifier 10 further includes a circuit board 17 , on which the detection component and the control component are disposed. The circuit board 17 is disposed between the fan 13 and the dehumidification assembly 11 .

[0086] The circuit board 17 can be a PCBA board (printed circuit board 17 / finished circuit board 17), and the detection component and the control component can be welded to the circuit board 17. The circuit board 17 mainly plays the role of connecting and transmitting electrical energy. The detection component and the control component are installed on the circuit board 17 to realize the transmission tab control of the current.

[0087] In one embodiment, the dehumidifier 10 further includes a communication component 18 , which is disposed on the circuit board 17 . The communication component 18 is adapted to transmit the air humidity detected by the detection component to the terminal.

[0088] The terminal can be a computer, mobile phone, etc., and the communication component 18 can be a wired transmission terminal or a wireless transmission module. The detection component, control component, and communication component 18 are all arranged on the circuit board 17. The communication component 18 can transmit the humidity information detected by the detection component to the terminal, realizing real-time monitoring of the temperature and humidity inside the cabinet 20 and the temperature and humidity changes inside the dehumidifier 10 itself. Specifically, the data can be transmitted to the software interface of the terminal via wired transmission such as RS485 or wireless signals such as Bluetooth / 4G / 5G / 6G / WiFi. The operator can remotely monitor the temperature and humidity of the energy storage cabinet 100 and record the operating status through the software interface, so that abnormal conditions can be detected and troubleshooted in a timely manner.

[0089] With reference to FIG. 3 , in one embodiment, the dehumidifier 10 further includes a second foam 19 , which is disposed between the semiconductor cooling sheet 112 and the circuit board 17 .

[0090] The second foam 19 is made of high-density polyethylene or polyurethane. Within the energy storage cabinet 100, it isolates moisture and dust, thereby protecting the circuit board 17 from moisture and contamination. It also provides shock absorption and sound insulation, reducing vibration and noise during operation.

[0091] The energy storage cabinet 100 disclosed in this application utilizes a dehumidification assembly 11 with a semiconductor cooling plate 112 as its core to reduce the moisture content in the air, thereby lowering the relative humidity within the energy storage cabinet 100 and mitigating the accelerated aging of components within the energy storage cabinet 100 and the cabinet body 20 of the energy storage cabinet 100 due to excessive humidity within the cabinet. Furthermore, the detection component of the dehumidifier 10 accurately and in real time detects actual temperature and humidity changes within the dehumidifier 10 or the energy storage cabinet 100. When the air humidity is greater than or equal to 40% RH, the control component issues a first control instruction to activate the dehumidification assembly 11, ensuring that the dehumidifier 10 initiates dehumidification in advance of the impending condensation conditions within the energy storage cabinet 100. The dehumidifier 10 disclosed in this application shifts from passive condensation prevention to active condensation guidance, effectively preventing safety hazards such as equipment aging, material mildew or corrosion, electronic component breakdown, and metal structural corrosion within the energy storage cabinet 100, thereby extending the service life of the energy storage device.
