DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used in this utility model have the same meaning as those commonly understood by technicians in the technical field of this utility model. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this utility model includes any and all combinations of one or more related listed items.

[0037] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] For reference Figure 1 and Figure 2 The utility model provides 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 .

[0039] 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 .

[0040] There can be multiple or one battery pack 200, without limitation. The battery pack 200 can achieve the functions of energy storage, load balancing, backup power supply, energy saving and emission reduction in the energy storage cabinet 100. The battery pack 200 is sensitive to humidity. If the humidity is too high, it will cause problems such as internal short circuit and electrolyte leakage in the battery, and even cause fire in severe cases. A dehumidifier 10 needs to be placed in the energy storage cabinet 100 to reduce the humidity inside the energy storage cabinet 100 and keep the battery dry and safe.

[0041] The utility model provides an energy storage cabinet 100, comprising a cabinet body 20 and a dehumidifier 10. The cabinet body 20 encloses a closed space, and the dehumidifier 10 is accommodated in the closed space.

[0042] The number of dehumidifiers 10 may be one or more, without limitation.

[0043] The energy storage cabinet 100 further includes a cabinet door 21. When the cabinet door 21 is closed, the cabinet body 20 can be sealed to form a closed space. The cabinet door 21 can also be opened during installation, maintenance, etc. for easy operation. The energy storage cabinet 100 is also provided with a sealing member 22. The sealing member 22 is provided on the cabinet door 21 and is suitable for enhancing the sealing performance of the energy storage cabinet 100.

[0044] The enclosed energy storage cabinet 100 can reduce the air flow inside and outside the energy storage cabinet 100, reduce the impact of external conditions on the internal temperature and humidity of the energy storage cabinet 100, and make the internal humidity of the enclosed energy storage cabinet 100 not change significantly under normal circumstances. However, in actual transportation, installation, maintenance and replacement of battery packs 200, the cabinet door 21 of the energy storage cabinet 100 needs to be opened, which may cause the humidity inside the cabinet to exceed the working set threshold, so the enclosed energy storage cabinet 100 still has the function of dehumidification.

[0045] 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.

[0046] For reference Figure 1 In one embodiment, the energy storage cabinet 100 further includes a partition 30, and the number of the partitions 30 can be multiple. The partitions 30 divide the cabinet body 20 into multiple spaces. The partitions 30 can also support the battery packs 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.

[0047] The partition 30 and the cabinet 20 may be an integrated structure, that is, the partition 30 and the cabinet 20 are an integrated structure made by an integrated molding process, and the integrated molding process may be stamping, casting, etc., without limitation. The partition 30 and the cabinet 20 may also be a split structure, and the partition 30 and the cabinet 20 may be connected and fixed by welding, bonding, clamping, screwing, etc.

[0048] 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 screwed, clamped, bonded, etc., without limitation. The energy storage cabinet 100 and the dehumidifier 10 adopt a split design and detachable connection, which is convenient for the production, installation and commissioning of the energy storage cabinet 100, and is also conducive to subsequent fault maintenance and daily maintenance. When the dehumidifier 10 fails to work normally, the cabinet door 21 of the energy storage cabinet 100 can be directly opened to replace the independent dehumidifier 10, which simplifies the operation.

[0049] In one embodiment, the energy storage cabinet 100 is also provided with a camera, which is used to monitor the real-time image inside the cabinet 20 , so as to make a more reasonable judgment on the health condition inside the cabinet 20 , which is beneficial to the safe use, evaluation and maintenance of the energy storage cabinet 100 .

[0050] For reference Figure 3 The utility model provides a dehumidifier 10, which is suitable for being arranged in a cabinet 20 of an energy storage cabinet 100. The dehumidifier 10 includes a detection component, a control component and a dehumidification component 11. The detection component is suitable for detecting the air humidity in 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. And the dehumidification component 11 is electrically connected to the control component and works according to the first control instruction to condense the moisture in the air in the energy storage cabinet 100 into dew.

[0051] 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.

[0052] The detection component may be a sensor, a capacitor, a resistor, etc. The control component may be an integrated circuit, a chip, etc.

[0053] The dehumidifier 10 of the utility model is provided with a detection component, a control component and a dehumidification component 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 make the dehumidification component 11 work, thereby ensuring that the dehumidifier 10 starts dehumidification in advance when the condensation condition is about to be reached in the energy storage cabinet 100. The dehumidifier 10 changes the passive condensation prevention mode to the active condensation guidance mode, which can effectively prevent the safety hazards such as aging of equipment, mildew or corrosion of materials, breakdown of electronic devices and rust of metal structural parts in the energy storage cabinet 100, and prolong the working time of the energy storage cabinet 100.

[0054] For reference Figure 3 In one embodiment, the dehumidification component 11 includes a cold end radiator 111, a semiconductor refrigeration sheet 112 and a hot end radiator 113. The semiconductor refrigeration sheet 112 has a cold surface and a hot surface arranged opposite to each other. The cold end radiator 111 is connected to the cold surface, and the hot end radiator 113 is connected to the hot surface.

[0055] The materials of the semiconductor cooling sheet 112 mainly include silicon-based semiconductor materials, germanium-based semiconductor materials, selenium-based semiconductor materials, and glass-ceramic semiconductor materials, etc. The semiconductor cooling sheet 112 utilizes the Peltier effect of semiconductors. When current passes through a loop composed of different conductors, in addition to generating irreversible Joule heat, heat absorption and heat release phenomena will occur at the joints of different conductors depending on the direction of the current.

[0056] The hot end radiator 113 is an important component for dissipating the heat of the hot end. The hot end radiator 113 is made of copper, aluminum, stainless steel, etc. The hot end radiator 113 can be fin-type, heat pipe-type, flat-plate type, etc.

[0057] The cold end heat sink 111 is connected to the cold surface to expand the temperature difference between the cold surface and the hot surface of the semiconductor cooling plate 112, so as to facilitate the generation of condensation.

[0058] A heat-insulating foam 114 is also provided between the semiconductor cooling sheet 112 and the hot end heat sink 113, which may be air heat-insulating foam, rock wool heat-insulating foam, glass wool heat-insulating foam, ceramic fiber heat-insulating foam, etc. The heat-insulating foam 114 is mainly used to reduce the influence of the heat generated by the hot surface on the electronic components such as the circuit board 17 in the dehumidifier 10. A groove is provided on the heat-insulating foam 114, and the hot surface of the semiconductor cooling sheet 112 extends into the groove and is connected to the hot end heat sink 113, which dissipates heat from the hot end heat sink 113.

[0059] The cold-end heat sink 111 , the semiconductor cooling sheet 112 and the hot-end heat sink 113 may be connected by bonding, clamping, screwing or the like.

[0060] The Peltier effect of semiconductors is used to achieve a temperature difference between the cold surface and the hot surface, and the humid gas in the enclosed space of the energy storage cabinet 100 is actively sucked into the dehumidifier 10 under the action of the fan 13. The water vapor is cooled and condensed into water after passing through the dehumidification component 11, thereby realizing a transition from passively preventing condensation to actively guiding condensation, which is conducive to ensuring that the air humidity in the energy storage cabinet 100 is always below 40% RH, and is conducive to improving the service life and safety of components such as the battery pack 200.

[0061] For reference Figure 3 In one embodiment, the dehumidifier 10 further includes a housing 12, the housing 12 encloses a receiving cavity, and the dehumidification component 11 is received in the receiving cavity. The housing 12 includes a top plate 121 and a bottom plate 122 arranged opposite to each other, the dehumidification component 11 is arranged on a side close to the bottom plate 122 relative to the detection component, and air flows from the dehumidification component 11 to the detection component side.

[0062] The housing 12 may be an integral structure, that is, an integral structure made by an integral molding process, and the integral 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.

[0063] 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.

[0064] The detection element may be disposed in the receiving cavity or not, without limitation. The detection element can accurately collect the real temperature and humidity changes inside the dehumidifier 10 or the energy storage cabinet 100 in real time, ensuring that the dehumidifier 10 starts dehumidification in advance when the condensation condition is about to be reached in the energy storage cabinet 100, which is conducive to ensuring the stability of the humidity of the working environment of the battery pack 200 and extending the service life of the battery pack 200.

[0065] For reference Figure 3 In one embodiment, the dehumidifier 10 further includes a fan 13, which is fixedly connected to the top plate 121, and is also electrically connected to the control component. The fan 13 is suitable for accelerating the flow of air.

[0066] 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 the control component issues a second control instruction, the fan 13 does not work.

[0067] 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.

[0068] The fan 13 can be an axial flow fan 13, which 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 soon as possible.

[0069] For reference 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.

[0070] The funnel 14 and the bottom plate 122 may be connected by screw connection, clamping connection, bonding connection, etc., without limitation. Optionally, a mounting hole 1221 is provided 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.

[0071] The dehumidifier 10 uses a semiconductor cooling sheet 112 to generate a temperature difference between the upper and lower surfaces when it is powered on, and actively sucks the humid gas in the enclosed space of the energy storage cabinet 100 into the dehumidifier 10 under the action of the fan 13. The water vapor cools down and condenses into water after passing through the dehumidification component 11, and drips into the funnel 14 in the dehumidifier 10 under the action of natural gravity, and then is discharged from the dehumidifier 10 and the energy storage cabinet 100 through the drain pipe 15. The dehumidifier 10 of the utility model has a small space volume, occupies less internal space of the energy storage cabinet 100, and only works when the humidity in the cabinet is detected to be greater than or equal to 40% RH, which can achieve the effects of energy saving, environmental protection and effective dehumidification.

[0072] For reference Figure 3 In one embodiment, a first air inlet 1222 is opened on the bottom plate 122 , and the first air inlet 1222 is arranged on the bottom plate 122 and corresponds to the hot end heat sink 113 .

[0073] The first air inlet 1222 may be a plurality of through holes arranged at intervals, or may be a single through hole. The shape of the through hole may be strip, circular, rectangular, etc., without limitation.

[0074] The provision of the first air inlet 1222 can improve the heat dissipation effect of the hot end heat sink 113 , which is beneficial to increasing the service life of the semiconductor cooling sheet 112 .

[0075] In one embodiment, the shell 12 also includes a first side plate 123 , which connects the bottom plate 122 and the top plate 121 , and the cold end heat sink 111 is located on the side of the semiconductor cooling plate 112 facing the first side plate 123 , and the first side plate 123 is provided with a second air inlet 1231 .

[0076] The second air inlet 1231 may be a plurality of through holes arranged at intervals, or may be a single through hole. The shape of the through hole may be strip, circular, rectangular, etc., without limitation.

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.

[0078] The housing 12 further includes a second side plate 124 disposed opposite to the first side plate 123, and the second side plate 124 is connected and fixed to the cabinet 20. The second side plate 124 and the cabinet 20 may be connected and fixed to the cabinet 20 in a detachable manner such as screw connection, clamping connection, or bonding, which is convenient for subsequent maintenance and replacement.

[0079] For reference Figure 3In one embodiment, the dehumidifier 10 further includes a first foam 16 , which is disposed between the first side plate 123 and the cold end radiator 111 , and is disposed corresponding to the second air inlet 1231 .

[0081] The shape of the first foam 16 is configured to correspond to the shape of the second air inlet 1231 .

[0082] The first foam 16 is arranged at the second air inlet 1231 to prevent dust and other impurities in the energy storage cabinet 100 from entering the dehumidifier 10 and affecting the service life of the dehumidifier 10 .

[0083] In one embodiment, the dehumidifier 10 further includes a circuit board 17 , on which the detection component and the control component are disposed, and the circuit board 17 is disposed between the fan 13 and the dehumidification component 11 .

[0084] 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 ear control of the current.

[0085] In one embodiment, the dehumidifier 10 further includes a communication component 18, which is disposed on the circuit board 17, and the communication component 18 is suitable for transmitting the air humidity detected by the detection component to the terminal.

[0086] The terminal can be a computer, a mobile phone, etc., and the communication component 18 can be a wired transmission terminal or a wireless transmission module. The detection component, the control component and the 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, so as to realize 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 software interface of the terminal can be transmitted through 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 operation status through the software interface, and can timely detect abnormal conditions and perform troubleshooting.

[0087] For reference Figure 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 .

[0088] The second foam 19 is made of high-density polyethylene or polyurethane material. In the energy storage cabinet 100, the second foam 19 can isolate moisture and dust from entering, thereby protecting the circuit board 17 from moisture and pollution. At the same time, the second foam 19 can also play a role in shock absorption and sound insulation, reducing vibration and noise during equipment operation.

[0089] The energy storage cabinet 100 of the utility model uses a dehumidification component 11 with a semiconductor cooling sheet 112 as the core to reduce the water content in the air, thereby reducing the relative humidity inside the energy storage cabinet 100, slowing down the aging of the components in the energy storage cabinet 100 and the cabinet body 20 of the energy storage cabinet 100 due to excessive humidity in the cabinet. In addition, the detection component of the dehumidifier 10 can accurately collect the real temperature and humidity changes inside the dehumidifier 10 or the energy storage cabinet 100 in real time, and when the air humidity is greater than or equal to 40% RH, the control component sends a first control instruction to start the dehumidification component 11, ensuring that the dehumidifier 10 starts dehumidification in advance when the condensation condition is about to be reached in the energy storage cabinet 100. The dehumidifier 10 of the utility model changes the passive condensation prevention mode to the active condensation guidance mode, which can effectively prevent the safety hazards such as aging of equipment in the energy storage cabinet 100, mildew or corrosion of materials, breakdown of electronic components and rust of metal structural parts, and extend the service life of the energy storage device.
