SUMMARY

[0004] In the related art, the dehumidification scheme of a 20-foot 5MWH liquid-cooled energy storage container includes setting 1-2 compressors to dehumidify. The compressor air conditioner is usually directly fixed on the side plate of the energy storage container due to its large size, thereby occupying more space in the length direction and width direction of the energy storage container. Therefore, using a large-volume compressor air conditioner to dehumidify on a high-energy-density energy storage container will cause the size design of the container to exceed the standard and there will be uneven dehumidification effect.

[0006] a box body, the box body comprising a top cover and a bottom cover arranged oppositely, and the inside of the box body being provided with a plurality of battery clusters;

[0007] a dehumidifier, the length and the width of the dehumidifier being greater than the thickness of the dehumidifier, the dehumidifier being arranged between the bottom of the plurality of battery clusters and the bottom cover, and the thickness direction of the dehumidifier being coincided with the height direction of the box body. ADVANTAGEOUS EFFECTS

[0008] The energy storage container provided by the present application arranges the dehumidifier in the interval between the bottom of the battery cluster and the bottom cover, and arranges the thickness direction of the dehumidifier, which has a smaller size, to be coincided with the height direction of the box body, so that the space occupied by the dehumidifier in the inside of the box body is smaller, thereby effectively improving the situation that the size design of the energy storage container exceeds the standard due to the arrangement of the dehumidifier.

[0021] In the present application, the orientation words such as "up" and "down" generally refer to the up and down in the actual use or working state of the device, specifically the direction of the drawing surface in the drawing, unless otherwise stated. "Inner" and "outer" refer to the outline of the device.

[0022] The energy storage container usually needs to be exposed to the outdoor for work. The battery modules and other power equipment inside the energy storage container are affected by the humid environment, which are prone to be damp and affect their normal operation, and even be corroded, thereby affecting their service life.

[0023] In the related art, the dehumidification scheme of a 20-foot 5MWH liquid-cooled energy storage container includes setting a compressor air conditioner or a coil type dehumidifier to dehumidify. The compressor air conditioner is bulky, and its use on a high energy density energy storage container can cause the size of the container to exceed the design standard and result in uneven dehumidification. The coil type dehumidifier usually needs to be connected in series with the pipeline of the liquid cooling machine, resulting in poor low-temperature dehumidification effect of the coil type dehumidifier and no dehumidification capacity of the coil type dehumidifier when the liquid cooling machine is not working.

[0024] The compressor air conditioner dehumidifier or the coil type dehumidifier is usually directly fixed on the side plate of the box body. Due to the large size of the compressor air conditioner dehumidifier or the coil type dehumidifier, it occupies a large space in the length direction or the width direction of the box body, causing the size of the energy storage container to exceed the design standard.

[0025] In the embodiments of the present application, the arrangement scheme of the dehumidifier inside the energy storage container is improved, thereby solving the technical problem that the arrangement of a large-sized dehumidifier inside the energy storage container causes the size of the container to exceed the design standard.

[0026] Referring to FIGS. 1-5, an energy storage container 1 according to an embodiment of the present application includes a box body 10 including oppositely arranged top and bottom covers 11 and 12, a plurality of battery clusters 20 arranged inside the box body 10, and at least one dehumidifier 30 arranged inside the box body 10. The box body 10 includes a length direction X, a width direction Y, and a height direction Z perpendicular to each other. The dehumidifier 30 includes a length direction A, a width direction B, and a thickness direction C perpendicular to each other. The dehumidifier 30 has a length extending along the length direction A, a width extending along the width direction B, and a thickness extending along the thickness direction C. The length and the width of the dehumidifier 30 are both greater than the thickness of the dehumidifier 30. The dehumidifier 30 is arranged in a space between the bottom of the plurality of battery clusters 20 and the bottom cover 12, and the thickness direction of the dehumidifier 30 coincides with the height direction of the box body 10.

[0027] By arranging the dehumidifier 30 in the space between the bottom of the battery cluster 20 and the bottom cover 12, and by coinciding the thickness direction of the dehumidifier 30 with the height direction of the box body 10, the space occupied by the dehumidifier 30 inside the box body 10 can be effectively reduced. On the one hand, more battery modules 21 can be arranged in the space in the height direction of the energy storage container 1, thereby improving the space utilization in the height direction of the energy storage container 1. On the other hand, the inventor found that by arranging the dehumidifier 30 in a horizontal position inside the box body 10, the problem of the size of the container exceeding the design standard caused by the arrangement of a large dehumidifier 30 can be effectively improved.

[0028] Further referring to the figures 1-4, a plurality of said dehumidifiers 30 are arranged in the interior of said container 10, and a plurality of said battery clusters 20 are arranged in the interior of said container 10, and each said dehumidifier 30 corresponds to at least one said battery cluster 20.

[0029] By arranging a plurality of said dehumidifiers 30 in the interior of said energy storage container 1, on the one hand, the volume of each said dehumidifier 30 can be reduced, thereby facilitating further reduction of the space occupied by said dehumidifiers 30 in the height direction of said container 10; on the other hand, arranging a plurality of small dehumidifiers 30 in the interior of said container 10 is more flexible in terms of arrangement position and arrangement mode than arranging a large dehumidifier 30 in the interior of said container 10; and on the third hand, arranging a plurality of said dehumidifiers 30 in the interior of said container 10 and corresponding to at least one said battery cluster 20, said dehumidifiers 30 can be arranged uniformly according to the arrangement of said battery clusters 20, thereby achieving uniform dehumidification effect in the interior of said container 10.

[0030] In the embodiment, said battery cluster 20 is configured as a plurality of battery modules 21 arranged in the height direction of said container 10, and said battery modules 21 are connected in series, in parallel or in a mixed manner to form said battery cluster 20 with a certain voltage and capacity, thereby meeting the capacity design requirements of said energy storage container 1.

[0031] In order to enable said dehumidifiers 30 to complete dehumidification within a required dehumidification time, the inventor has found, through research, that the number n of said dehumidifiers 30 arranged in the interior of said container 10 satisfies the formula n = 24*Q*V / (t*C), wherein C is the dehumidification capacity of each said dehumidifier, Q is the amount of water vapor contained in each kilogram of dry air in the interior of said container 10, V is the air volume in the interior of said container 10, and t is the dehumidification time.

[0032] In terms of 24h dehumidification capacity, the unit of C is set to ml / 24h, and the dehumidification capacity C of said dehumidifier 30 suitable for use in said energy storage container 1 is set to 500ml / 24h-1000ml / 24h. In a specific implementation, the dehumidification capacity of said dehumidifier 30 can be 500ml / 24h, 600ml / 24h, 700ml / 24h, 800ml / 24h, 900ml / 24h, 1000ml / 24h, or a value between any two of the above values, or a range between any two of the above values.

[0033] The unit of Q is g / kg dry air, and Q is mainly affected by the temperature and relative humidity in the interior of the box 10, and thus is not specifically limited. It should be noted that the dehumidifier 30 is only used when the amount of water vapor contained in each kilogram of dry air in the interior of the box 10 is greater than a certain value, and the dehumidifier 30 is turned on for a certain period of time to reduce the amount of water vapor contained in each kilogram of dry air in the interior of the box 10 to below a specified value.

[0034] The unit of V is dm 3 It should be noted that V represents the remaining space in the interior of the box 10 after removing the space occupied by the plurality of battery clusters and other devices in the interior of the box, and the remaining space is filled with air.

[0035] The unit of t is h, and the dehumidification time t required in the interior of the energy storage container 1 is 1 h to 4 h. In a specific implementation, the dehumidification time t used by the energy storage container 1 is set to 1 h, 2 h, 4 h, or a value between any two of the above values, or a range between any two of the above values.

[0036] Taking a 20-foot 5MWH liquid-cooled energy storage container as an example, the ratio of the number n of dehumidifiers to the number m of battery clusters arranged in the interior of the box is not less than 1 / 3, wherein the dehumidification capacity C of each dehumidifier is set to 500 ml / 24 h to 1000 ml / 24 h, and / or the dehumidification time t is set to 1 h to 4 h.

[0037] It can be understood that if the ratio of the number n of dehumidifiers to the number m of battery clusters arranged in the interior of the energy storage container 1 is less than 1 / 3, the number n of dehumidifiers cannot meet the dehumidification effect of the energy storage container 1 within a specified dehumidification time. If the space in the interior of the box 10 allows, as many dehumidifiers 30 as possible are arranged in the interior of the box 10 to further improve the dehumidification effect and efficiency of the energy storage container 1. For example, if the dehumidification capacity of the dehumidifier 30 remains unchanged, four dehumidifiers arranged in the interior of the box 10 can complete dehumidification within 4 h, and sixteen dehumidifiers arranged in the interior of the box 10 can complete dehumidification within 1 h.

[0038] Further, each battery cluster 20 can correspondingly be provided with a group of dehumidifiers 30 or one dehumidifier 30, wherein the group of dehumidifiers 30 can include two or more dehumidifiers 30, and the appropriate number of dehumidifiers 30 can be arranged in the interior of the energy storage container 1 according to the humidity state of the environment required to be applied by the energy storage container 1 and the dehumidification capacity of a single dehumidifier 30.

[0039] 20 feet 5MWH liquid-cooled energy storage container, which is the highest volume-to-energy liquid-cooled energy storage system at present. Taking a 20 feet 5MWH liquid-cooled energy storage container as an example, the number of battery clusters 20 arranged inside the box 10 is 10-12, and the number of dehumidifiers 30 arranged inside the box 10 is 4-12. In a specific implementation, the number of dehumidifiers 30 arranged inside the box 10 can be 4, 5, 6, 7, 8, 9, 10, 11 or 12.

[0040] In a preferred implementation, one dehumidifier 30 is arranged at the bottom of each battery cluster 20, so as to balance the dehumidification effect. If the dehumidification performance of a single dehumidifier 30 is good, four dehumidifiers 30 can be arranged at the four corners of the battery compartment 15 of the box 10 under the condition that the dehumidification effect of the energy storage container 1 is sufficient, so that the overall box 10 has a balanced dehumidification effect.

[0041] As shown in FIGS. 1-4, the box 10 includes oppositely arranged top cover 11 and bottom cover 12, and a plurality of dehumidifiers 30 are arranged in the space between the bottom of the plurality of battery clusters 20 and the bottom cover 12.

[0042] The box 10 further includes left side plate 13, right side plate 14, front side plate and rear side plate connected between the top cover 11 and the bottom cover 12, wherein the left side plate 13 and the right side plate 14 are oppositely arranged, and the front side plate and the rear side plate are oppositely arranged.

[0043] By arranging a plurality of dehumidifiers 30 in the space between the bottom of the plurality of battery clusters 20 and the bottom cover 12, the condensed water generated by the dehumidifiers 30 during the dehumidification process can be directly discharged through the bottom cover 12, thereby improving the dehumidification effect of the dehumidifiers 30. Compared with arranging the dehumidifiers 30 on any one of the left side plate 13, the rear side plate, the front side plate and the rear side plate, one end of the dehumidifier 30 needs to be connected to a complex drainage pipeline to discharge the condensed water, and a complex drainage pipeline needs to be additionally arranged inside the box 10, thereby increasing the complexity of the internal structure of the energy storage container 1 and further compressing the internal space of the box 10 occupied by the battery module 21.

[0044] Further referring to FIGS. 1-3, a plurality of drainage grooves 34 are arranged on the bottom cover 12, and the drainage grooves 34 are configured to be recessed from a portion of the bottom cover 12. Each dehumidifier 30 is provided with a water outlet 36, and the condensed water inside each dehumidifier 30 is discharged through the water outlet 36. The water outlet 36 of each dehumidifier 30 is arranged above the drainage groove 34, so that the water inside the dehumidifier 30 can be directly discharged into the drainage groove 34.

[0045] By arranging the water outlet 36 of the dehumidifier 30 above the drain groove 34, the condensed water generated by the dehumidifier 30 can directly enter the drain groove 34, thereby effectively simplifying the drain pipeline structure, improving the dehumidification efficiency, and simplifying the structure inside the energy storage container 1.

[0046] It should be noted that if the dehumidifier 30 is arranged above the drain groove 34, the water outlet 36 of the corresponding dehumidifier 30 is arranged on the body of the dehumidifier 30, and the water inside the dehumidifier 30 can directly drain into the drain groove 34 through the water outlet 36. If the dehumidifier 30 is arranged near the drain groove 34, the dehumidifier 30 further comprises a water outlet pipe, and the water outlet 36 of the water outlet pipe is arranged above the drain groove 34, thereby draining the water generated by the dehumidifier 30 into the drain groove 34.

[0047] With reference to FIGS. 1-4, 6 and 7, each of the battery clusters 20 is provided with one of the drain grooves 34, the box 10 comprises left and right side plates 13 and 14 connected between the top cover 11 and the bottom cover 12, the drain grooves 34 comprise a first drain groove 341 arranged near the left side plate 13 and a second drain groove 342 arranged near the right side plate 14, and the dehumidifiers 30 comprise a first group of dehumidifiers 31 and a second group of dehumidifiers 32 arranged in a spaced manner. The first group of dehumidifiers 31 is arranged corresponding to the first drain groove 341, and the second group of dehumidifiers 32 is arranged corresponding to the second drain groove 342.

[0048] By arranging the first group of dehumidifiers 31 near the left side plate 13 and the second group of dehumidifiers 32 near the right side plate 14, the first group of dehumidifiers 31 and the second group of dehumidifiers 32 can uniformly and quickly absorb the moisture inside the entire box 10, thereby avoiding the electrical equipment installed near the left side plate 13 or the right side plate 14 from being corroded by the moisture.

[0049] In a specific implementation, twelve battery clusters 20 are arranged inside the energy storage container 1, every six battery clusters 20 are arranged in a spaced manner along the length direction of the box 10, and every two battery clusters 20 are arranged in a spaced manner along the width direction of the box 10. Correspondingly, six drain grooves 34 are arranged on the bottom cover 12, and each battery cluster 20 is provided with one of the drain grooves 34. The first group of dehumidifiers 31 comprises two dehumidifiers 30 arranged near the front side plate and the rear side plate respectively, and the second group of dehumidifiers 32 comprises two dehumidifiers 30 arranged near the front side plate and the rear side plate respectively. Each of the drain grooves 34 is provided with two water outlets 35, and the six drain grooves 34 are provided with a total of twelve water outlets 35, and each of the water outlets 35 is arranged corresponding to one of the battery clusters 20.

[0050] As shown in FIG. 3 and FIG. 8, each of the dehumidifiers 30 is configured with two brackets, i.e., a first bracket 331 and a second bracket 332, and the dehumidifiers 30 are fixed to the bottom cover 12 through the first bracket 331 and the second bracket 332. The first bracket 331 and the second bracket 332 are respectively fixed to two sides of the drain groove 34, and the dehumidifiers 30 are arranged opposite to the drain groove 34.

[0051] The above-mentioned humidifier is installed on the bottom cover 12 by means of the first bracket 331 and the second bracket 332. One end of the first bracket 331 is fixed to one side of the dehumidifier 30, and the other end of the first bracket 331 is fixed to the bottom cover 12 at one side of the drain groove 34. One end of the second bracket 332 is fixed to the other side of the dehumidifier 30, and the other end of the second bracket 332 is fixed to the bottom cover 12 at the other side of the drain groove 34. The dehumidifiers 30 are arranged opposite to the drain groove 34, so that the condensed water generated by the dehumidifiers 30 during the dehumidification process can be directly discharged into the drain groove 34, and thus it is not necessary to provide an additional drainage pipeline structure, thereby effectively reducing the internal space of the cabinet 10 required for arranging the entire dehumidification system.

[0052] Further referring to FIG. 6 and FIG. 9, the length or width of the dehumidifier 30 is greater than the width of the drain groove 34.

[0053] It should be noted that, since the length or width of the dehumidifier 30 is greater than the width d of the drain groove 34, the condensed water flowing out from the bottom of the dehumidifier 30 can completely flow into the drain groove 34.

[0054] In some embodiments, the bottom of the drain groove 34 is provided with at least one drain port 35, and a drain pipe 37 is connected to the dehumidifier 30, and the end of the drain pipe 37 extends to the drain port 35.

[0055] When the spacing between the bottom outlet of the dehumidifier 30 and the drain groove 34 is large, a drain pipe 37 can be connected to the bottom outlet of the dehumidifier 30, which further directly guides the water generated inside the dehumidifier 30 to the drain port 35, thereby improving the drainage efficiency.

[0056] As shown in FIG. 4, FIG. 5 and FIG. 7, the energy storage container 1 further comprises a high-voltage tank 40, and the battery cluster 20, the high-voltage tank 40 and the dehumidifier 30 are sequentially arranged along the height direction of the cabinet 10.

[0057] In the energy storage container 1, the high-voltage box 40 is arranged as a sealed box structure for carrying and distributing high-voltage power equipment, and high-voltage equipment for managing, distributing and controlling high-voltage power in the energy storage container 1 is installed inside the high-voltage box 40, which includes high-voltage switch equipment, transformers and protection devices, etc. A dehumidifier 30 is arranged at the bottom of the high-voltage box 40, which can effectively prevent moisture from causing the high-voltage equipment inside the high-voltage box 40 to work unstably.

[0058] By arranging the battery cluster 20, the high-voltage box 40 and the dehumidifier 30 in sequence along the height direction of the box 10, the height space inside the box 10 can be fully utilized, and separate equipment compartments for placing the high-voltage box 40 and the dehumidifier 30 along the length direction of the box 10 can be avoided, thereby improving the space utilization rate of the box 10 in the length direction.

[0059] It should be noted that by arranging the dehumidifier 30 below the high-voltage box 40, the fan inside the dehumidifier 30 can carry away the heat generated by the components inside the high-voltage box 40 when it is running, thereby making the temperature inside the box 10 more uniform.

[0060] Further referring to FIGS. 9 and 10, the length of the dehumidifier 30 is arranged to be 200mm-300mm; and / or, the width of the dehumidifier 30 is arranged to be 100mm-200mm; and / or, the thickness of the dehumidifier 30 is arranged to be 20mm-80mm.

[0061] A plurality of dehumidifiers 30 can be arranged to be the same size and specification, or a part of the dehumidifiers 30 can be arranged to be one size and specification, and another part of the dehumidifiers 30 can be arranged to be another size and specification, according to the different arrangement positions of the dehumidifiers 30. For example, in one example, the size of each dehumidifier 30 is arranged to be 300mm*130mm*50mm.

[0062] The length L of each dehumidifier 30 can be set to 200 mm, 210 mm, 220 mm, 230 mm, 240 mm, 250 mm, 260 mm, 270 mm, 280 mm, 290 mm, 300 mm, and a value between any two of the above values or a range between any two of the above values. The width W of each dehumidifier 30 can be set to 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, 160 mm, 170 mm, 180 mm, 190 mm, 200 mm, and a value between any two of the above values or a range between any two of the above values. The thickness h of each dehumidifier 30 can be set to 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, and a value between any two of the above values or a range between any two of the above values.

[0063] For example, a 20-foot 5MWH liquid-cooled energy storage container, the energy storage container 1 includes a length extending along a length direction X, a width extending along a width direction Y, and a height extending along a height direction Z, wherein the length of the energy storage container 1 is greater than the width thereof, and the width of the energy storage container 1 is greater than the height thereof. A plurality of dehumidifiers 30 are configured to be horizontally accommodated in the interior of the container body 10, and the length direction of the dehumidifier 30 coincides with the length direction of the container, the width direction of the dehumidifier 30 coincides with the width direction of the container, and the thickness direction of the dehumidifier 30 coincides with the height direction of the container. A plurality of dehumidifiers 30 are arranged along the length direction of the energy storage container 1. If the length of each dehumidifier 30 is greater than 300 mm, the space occupied by the plurality of dehumidifiers 30 in the length direction of the container body 10 is relatively large, and it is not conducive to maintaining sufficient spacing between adjacent dehumidifiers 30. If the length of each dehumidifier 30 is less than 200 mm, under the condition that the thickness and width of the dehumidifier 30 are limited, the volume of a single dehumidifier 30 is relatively small, which further leads to insufficient dehumidification capacity of a single dehumidifier 30, and further affects the dehumidification function inside the energy storage container 1. Further, a plurality of dehumidifiers 30 are arranged along the width direction of the energy storage container 1. If the width of each dehumidifier 30 is greater than 200 mm, the space occupied by the plurality of dehumidifiers 30 in the width direction of the container body 10 is relatively large, and it is not conducive to maintaining sufficient spacing between adjacent dehumidifiers 30. If the width of each dehumidifier 30 is less than 100 mm, under the condition that the length and thickness of the dehumidifier 30 are limited, the volume of a single dehumidifier 30 is relatively small, which further leads to insufficient dehumidification capacity of a single dehumidifier 30, and further affects the dehumidification function inside the energy storage container 1. A plurality of dehumidifiers 30 are arranged along the height direction of the energy storage container 1. If the thickness of each dehumidifier 30 is greater than 80 mm, the space occupied by the dehumidifier 30 in the height direction of the container body 10 is relatively large. If the thickness of each dehumidifier 30 is less than 20 mm, under the condition that the length and width of the dehumidifier 30 are limited, the volume of a single dehumidifier 30 is relatively small, which further leads to insufficient dehumidification capacity of a single dehumidifier 30, and further affects the dehumidification function inside the energy storage container 1.

[0064] As shown in FIGS. 3 and 4, the container body 10 is provided with a battery compartment 15, an electrical compartment 17, and a liquid cooling compartment 16 which are separated from each other. The battery compartment 15 is separated from the electrical compartment 17 or the liquid cooling compartment 16 along the length direction X of the container body 10. The electrical compartment 17 is separated from the liquid cooling compartment 16 along the width direction Y of the container body 10. The battery compartment 15 is used to place a plurality of battery clusters 20. The electrical compartment 17 is used to place a busbar cabinet and / or a power distribution cabinet. The liquid cooling compartment 16 is used to place liquid cooling equipment. The dehumidifier 30 is arranged in the area where the battery compartment 15 is located.

[0065] By separating the electrical compartment 17, the liquid cooling compartment 16 and the battery compartment 15, it is beneficial to independently control the temperature and humidity of the electrical compartment 17, the liquid cooling compartment 16 and the battery compartment 15, on the one hand, it is beneficial to maintain the electrical equipment such as the busbar cabinet and the power distribution cabinet in the electrical compartment 17 to run in a suitable working environment, and improve the stability and reliability of the electrical equipment such as the busbar cabinet and the power distribution cabinet; on the other hand, the independent temperature and humidity control of the battery compartment 15 can control the working environment of the battery cluster 20 and prolong the service life of the battery cluster 20.

[0066] In a specific implementation, a partition plate is arranged in the inside of the box body 10, the partition plate includes a longitudinal extension part for separating the battery compartment 15 and the electrical compartment 17 or the liquid cooling compartment 16, and a transverse extension part for separating the electrical compartment 17 and the liquid cooling compartment 16.
