Description

Technical Field

[0001] The present invention relates to the field of containers, and particularly to an energy storage container. Background Art

[0002] An energy storage container integrates energy storage units in a container and is applied in systems such as new energy, distributed power generation, and grid peak shaving and valley filling, realizing the rapid integration and rapid commissioning of energy storage devices. With the development of energy storage technology, the number of energy storage units in container energy storage devices is increasing continuously. During use, the energy storage units need to dissipate heat in a timely manner. To improve the heat dissipation efficiency of the energy storage units, the existing technology is developing from air-cooled heat dissipation to liquid cooling of the energy storage units.

[0003] In the existing liquid cooling solutions for energy storage units, heat exchange elements are provided on the batteries. The liquid in the heat exchange elements exchanges heat with the batteries and then is connected to a liquid cooling unit through pipelines. After heat release by the liquid cooling unit, it returns to the heat exchange elements, and so on to achieve liquid cooling and temperature reduction of the batteries. To prevent the heat generated by the liquid cooling unit from affecting the temperature reduction of the batteries, a partition wall is provided in the container to divide the accommodation cavity into a battery compartment and an equipment compartment, separating the liquid cooling unit from the batteries. However, since the battery compartment and the equipment compartment are adjacent, the temperature in the area of the battery compartment close to the liquid cooling unit is relatively high, resulting in a temperature difference at different positions in the battery compartment, thus affecting the temperature reduction of the batteries.

However, these embodiments do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0036] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Referring to Figures 1 to 6 As shown, a preferred embodiment of the present invention provides an energy storage container. The energy storage container uses a liquid cooling type cooling device to dissipate heat from the battery, so that the battery temperature is constant, ensuring that the battery is in the best working state.

[0038] Specifically, with reference to Figure 1 and Figure 2 As shown, an energy storage container includes a box body 10, a battery cluster 20, and a liquid cooling unit 30. In this embodiment, the battery cluster 20 and the liquid cooling unit 30 are arranged in the box body 10, which can effectively protect the battery cluster 20 and the liquid cooling unit 30 and can be transported with the box body 10.

[0039] Specifically, the box body 10 includes an outer shell 11 forming an accommodation cavity and a partition wall 12 arranged inside the outer shell 11. The partition wall 12 divides the accommodation cavity into a battery compartment 10a and an equipment compartment 10b, and the equipment compartment 10b communicates with the outside of the outer shell 11. In this embodiment, the partition wall 12 is made of a sandwich insulation board, which is composed of two steel plates and rock wool supported between the two steel plates. It not only has good installation strength but also can play a role in heat insulation, thereby reducing the heat exchange between the battery compartment 10a and the equipment compartment 10b. The equipment compartment 10b can communicate with the outside of the outer shell 11 and exchanges heat with the outside air of the outer shell 11 through the flow of gas.

[0040] Specifically, the battery cluster 20 is arranged in the battery compartment 10a and includes a battery and a heat exchange member connecting the battery. In this embodiment, a flow channel is arranged in the heat exchange member, and when a liquid flows through the flow channel, the liquid can exchange heat with the heat exchange member and the battery.

[0041] Specifically, the liquid cooling unit 30 is arranged in the equipment compartment 10b and is connected to the heat exchange member through a pipeline. In this embodiment, the liquid in the flow channel of the heat exchange member flows into the liquid cooling unit 30 through the pipeline. After being cooled by exchanging heat with the outside air of the outer shell 11 by the liquid cooling unit 30, the cooled liquid then flows back into the flow channel of the heat exchange member through the pipeline, and so on in a cycle to achieve liquid cooling of the battery.

[0042] Furthermore, the housing 11 includes a first side plate 11a and a second side plate 11b that are arranged opposite to each other in the width direction, an end wall 11c and a ventilated door 11d that are connected to the first side plate 11a and the second side plate 11b and are arranged opposite to each other, and the partition wall 12 is connected between the first side plate 11a and the second side plate 11b. In this embodiment, the battery compartment 10a and the equipment compartment 10b are arranged along the length direction of the housing 11, which saves the length of the partition wall 12 and maximizes the use of the battery compartment 10a, so that the number of batteries installed in the battery compartment 10a is maximized.

[0043] Furthermore, the liquid cooling unit 30 has a liquid cooling exhaust port 32 exposed in the equipment compartment 10b, and the liquid cooling exhaust port 32 is directly opposite to the ventilated door 11d. In this embodiment, the liquid cooling exhaust port 32 is directly opposite to the end of the housing 11 away from the battery compartment 10a, so as to prevent the high-temperature gas discharged from the liquid cooling unit 30 from affecting the ambient temperature around the battery compartment 10a, thereby ensuring the liquid cooling effect of the battery.

[0044] The partition wall 12 is connected between the first side panel 11a and the second side panel 11b so that the battery compartment 10a and the equipment compartment 10b are arranged along the length direction of the outer shell 11, and the liquid cooling exhaust port 32 is directly opposite to the end of the outer shell 11 away from the battery compartment 10a, so as to prevent the high-temperature gas discharged by the liquid cooling unit 30 from affecting the ambient temperature around the battery compartment 10a, thereby ensuring the liquid cooling effect of the battery.

[0045] Mate Reference Figure 3 As shown, further, the liquid cooling unit 30 also has a liquid cooling air inlet 33 exposed in the equipment compartment 10b, the liquid cooling air inlet 33 is directly opposite to the breathable box door 11d, and the horizontal height of the liquid cooling air inlet 33 is lower than the liquid cooling exhaust port 32. In this embodiment, the liquid cooling unit 30 adopts the method of lower air intake and upper air outlet to exchange heat with the outside of the shell 11, and the liquid cooling air inlet 33 and the liquid cooling exhaust port 32 are both facing the breathable box door 11d, and are located at one end of the shell 11 away from the battery compartment 10a, which further reduces the influence of the airflow during the heat exchange process of the liquid cooling unit 30 on the ambient temperature of the battery compartment 10a.

[0046] Furthermore, the box body 10 also includes an air inlet 13 arranged on the outer shell 11 and connecting the battery compartment 10a with the outside of the outer shell 11, and an air outlet 14 arranged on the partition wall 12 and connecting the battery compartment 10a with the equipment compartment 10b. The energy storage container also includes a driving fan 40 arranged in the air inlet 13 and / or the air outlet 14.

[0047] In this embodiment, the driving fan 40 disposed in the air inlet 13 and / or the air outlet 14 drives the air flow in the battery compartment 10a to flow, thereby reducing the temperature difference between various positions in the battery compartment 10a and accelerating the cooling of the battery.

[0048] Moreover, the air flow in the battery compartment 10a flows in from outside the outer shell 11 and flows into the equipment compartment 10b, thereby accelerating the gas flow in the equipment compartment 10b and also accelerating the gas in the equipment compartment 10b to flow out of the outer shell 11. In this way, it can not only reduce the temperature difference existing at various positions in the equipment compartment 10b, but also accelerate the heat dissipation of the equipment compartment 10b.

[0049] In addition, compared with the single air-cooled energy storage container, this solution combines liquid cooling and air cooling methods, and also cancels the air duct in the original air-cooled energy storage container, thereby saving the installation space inside the outer shell 11, and then installing more battery clusters 20, improving the energy density, and not affecting the cooling effect of the battery.

[0050] Among them, an electric louver and a pressure relief valve are provided on the air inlet 13, and the driving fan 40 is configured as an explosion-proof fan. When the gas pressure in the battery compartment 10a reaches the set value, the pressure relief valve is automatically opened for pressure relief operation.

[0051] Specifically, the partition wall 12 extends along the width direction of the outer shell 11, and the battery compartment 10a is formed between the partition wall 12, the end wall 11c, the first side plate 11a and the second side plate 11b. In this embodiment, the partition wall 12 extends along the width direction of the outer shell 11 and is parallel to the end wall 11c, so that the battery compartment 10a has a rectangular structure, which is convenient for the installation of the partition wall 12 and the battery cluster 20. Among them, four groups of battery clusters 20 are arranged oppositely in the battery compartment 10a, and the battery cluster 20 includes two relatively arranged battery racks and the batteries and battery control boxes installed on the battery racks.

[0052] Furthermore, the air inlet 13 is provided on the end wall 11c. In this embodiment, the end plate 11c and the partition wall 12 are arranged opposite to each other along the length direction of the outer shell 11, so as to maximize the distance between the air inlet 13 and the air outlet 14, increase the time for the gas to flow from the air inlet 13 into the battery compartment 10a to the gas to flow out of the battery compartment 10a from the air outlet 14, thereby increasing the heat exchange time of the gas in the battery compartment 10a and improving the air-cooling efficiency of the battery compartment 10a.

[0053] Furthermore, the outer shell 11 further includes a breathable box door 11d connecting the first side plate 11a and the second side plate 11b and arranged opposite to the end wall 11c, and the liquid cooling unit 30 has a liquid cooling exhaust port 32 exposed in the equipment compartment 10b, and the liquid cooling exhaust port 32 is directly opposite to the breathable box door 11d.

[0054] In this embodiment, the ventilation box door 11d is configured as a double-opening steel mesh door, which maximally increases the heat exchange area of the equipment compartment 10b and facilitates the heat exchange between the equipment compartment 10b and the external air of the housing 11. The heat generated by the liquid cooling unit 30 is discharged through the liquid cooling exhaust port 32 and discharged from the ventilation box door 11d outside the housing 11. Since the ventilation box door 11d and the end wall 11c are oppositely arranged along the length direction of the housing 11, the distance between the ventilation box door 11d and the end wall 11c is maximally increased, thereby preventing the heat generated by the liquid cooling unit 30 from flowing to the end wall 11c and preventing the heat generated by the liquid cooling unit 30 from entering the battery compartment 10a through the air inlet 13 on the end wall 11c, and then ensuring the air cooling effect in the battery compartment 10a.

[0055] Further, the box body 10 further includes a partition 15 connecting the partition wall 12 and the first side plate 11a and located in the equipment compartment 10b. The partition 15 divides the equipment compartment 10b into a heat exchange chamber 10b1 and an electrical chamber 10b2. In this embodiment, the setting of the partition 15 can insulate between the heat exchange chamber 10b1 and the electrical chamber 10b2 and reduce the heat exchange between the heat exchange chamber 10b1 and the electrical chamber 10b2. The partition 15 can adopt the same structure as the partition wall 12, such as a sandwich heat preservation board. Of course, the partition can also adopt a structure different from that of the partition wall 12, as long as it can ensure the installation strength and play a role in heat insulation and heat preservation at the same time.

[0056] Specifically, the liquid cooling unit 30 is arranged in the heat exchange chamber 10b1, and the air outlet 14 is open towards the heat exchange chamber 10b1. In this embodiment, the setting of the partition 15 blocks the gas discharged from the air outlet 14 to a certain extent, thereby preventing the gas discharged from the air outlet 14 from directly flowing towards the liquid cooling unit 30 and generating a backflow. When the gas encounters the liquid cooling unit 30 and generates a backflow, the backflow will carry the heat generated by the liquid cooling unit 30, thereby increasing the heat around the air outlet 14 and generating the possibility of the heat flowing back into the battery compartment 10a from the air outlet 14. This solution avoids the occurrence of this situation.

[0057] Further, the liquid cooling unit 30 and the air outlet 14 are located on both sides of the symmetry plane of the first side plate 11a and the second side plate 11b. In this embodiment, as Figure 2 , the liquid cooling unit 30 and the air outlet 14 are arranged along the diagonal of the equipment compartment 10b, which maximally increases the distance between the air outlet 14 and the liquid cooling unit 30, thereby reducing the influence of the liquid cooling unit 30 on the air outlet 14.

[0058] Of course, in some embodiments, the liquid cooling unit 30 can also be located on the same side of the symmetry plane of the first side plate 11a and the second side plate 11b as the air outlet 14, that is, the liquid cooling unit 30 and the electrical chamber 10b2 are arranged along the diagonal of the equipment compartment 10b, which can enable the liquid cooling unit 30 to better exchange heat in the heat exchange chamber 10b1.

[0059] Further, the energy storage container further includes an energy storage converter 50 disposed in the heat exchange chamber 10b1 and opposite to the liquid cooling unit 30 in the width direction of the outer shell 11. In this embodiment, after the energy storage container is provided with the energy storage converter 50, it can be configured as a user-side energy storage box. In some embodiments, the energy storage container may also not have the energy storage converter 50, so as to be configured as a grid-side energy storage box. The energy storage converter 50 and the liquid cooling unit 30 are disposed opposite to each other in the width direction of the outer shell 11, the energy storage converter 50 and the air outlet 14 are disposed opposite to each other in the length direction of the outer shell, and the energy storage converter 50 and the electrical chamber 10b2 are disposed along the diagonal of the equipment compartment 10b, which can play a role in blocking the liquid cooling unit 30 and the air outlet 14, preventing the heat generated by the liquid cooling unit 30 from affecting the air outlet 14, and making the spatial layout in the equipment compartment 10b more reasonable.

[0060] Further, the energy storage converter 50 has a converter air inlet 51 and a converter air outlet 52 exposed in the heat exchange chamber 10b1. The converter air inlet 51 is directly opposite to the ventilation box door 11d, and the air outlet 14 is directly opposite to one end of the energy storage converter 50 having the converter air outlet 52. In this embodiment, the converter air inlet 51 and the converter air outlet 52 are disposed at both ends of the energy storage converter 50 in the length direction of the outer shell 11, and the converter air outlet 52 and the air outlet 14 are disposed opposite to each other in the length direction of the outer shell 11, preventing the gas discharged from the air outlet 14 from entering the energy storage converter 50 and accelerating the discharge of heat in the energy storage converter 50.

[0061] Specifically, the energy storage converter 50 is spaced apart from the partition wall 12. In this embodiment, a certain gap is provided between the energy storage converter 50 and the partition wall 12, which is convenient for heat dissipation and also convenient for later operators to maintain the energy storage converter 50 or the air outlet 14 in this gap.

[0062] With reference to Figure 3 As shown, specifically, the box body 10 further includes a ventilation side door 16 disposed on the second side plate 11b to open or close the heat exchange chamber 10b1. In this embodiment, the ventilation side door 16 is configured as a steel mesh door, so that the heat discharged from the converter air outlet 52 and the air outlet 14 can be quickly discharged from the heat exchange chamber 10b1 through the ventilation side door 16. Moreover, the ventilation side door 16 can be opened to maintain the energy storage converter 50 or the air outlet 14.

[0063] Further, the driving fan 40 is disposed within the air outlet 14, and the converter exhaust port 52 and the air outlet 14 are at different horizontal heights. In this embodiment, the gas within the battery compartment 10a is extracted by the driving fan 40 within the air outlet 14 and discharged into the heat exchange chamber 10b1. The energy storage converter 50 discharges heat using the converter exhaust port 52. By setting the converter exhaust port 52 and the air outlet 14 at different horizontal heights, it can be avoided that when the exhaust port 52 and the air outlet 14 discharge gas, there is mutual convection between the two. Preferably, driving fans 40 are provided both within the air outlet 14 and the air inlet 13, thereby accelerating the cooling of the battery compartment 10a.

[0064] With reference to Figure 4 As shown, the air inlet 13 and the air outlet 14 are located on both sides of the symmetry plane of the first side plate 11a and the second side plate 11b. The air outlet 14 and the air inlet 13 are at the same horizontal height, and the horizontal height where the air outlet 14 is located is higher than the horizontal height where the converter exhaust port 52 is located. In this embodiment, the air outlet 14 and the air inlet 13 are arranged along the diagonal of the battery compartment 10a to ensure that gas flow is generated everywhere inside the battery compartment 10a, ensuring that the gas entering the battery compartment 10a is fully heat-exchanged before being discharged, thereby improving the air-cooling efficiency. Both the air outlet 14 and the air inlet 13 are located at the top position of the box body 10, which can accelerate the discharge of the hot air at the top inside the battery compartment 10a, and the air-cooling effect is better.

[0065] Specifically, the partition 15 includes a first plate 15a connecting the partition wall 12, a second plate 15b connecting the first plate 15a and the first side plate 11a, and an electrical exhaust port 15c provided on the second plate 15b and communicating the electrical chamber 10b2 and the heat exchange chamber 10b1. In this embodiment, the first plate 15a is arranged parallel to the first side plate 11a, the second plate 15b is arranged parallel to the end wall 11c, and the first plate 15a and the second plate 15b are perpendicular to each other, making the electrical chamber 10b2 have a rectangular structure, thus facilitating the installation of the partition 15.

[0066] Specifically, the air outlet 14 is located between the first plate 15a and the second side plate 11b, and the liquid cooling unit 30 is located between the second plate 15b and the ventilation box door 11d. In this embodiment, as Figure 2 , the heat exchange chamber 10b1 has an "L" - shaped structure, avoiding the heat generated by the liquid cooling unit 30 from directly flowing towards the air outlet 14 and ensuring the air-cooling and temperature - lowering effect of the battery compartment 10a.

[0067] Further, the energy storage container further includes an exhaust fan 60 disposed within the electrical exhaust port 15c. In this embodiment, after the exhaust fan 60 is installed within the electrical exhaust port 15c, it can accelerate the gas flow between the second plate 15b and the ventilation box door 11d, thereby accelerating the discharge of the heat flow of the liquid cooling unit 30 from the heat exchange chamber 10b1, and can also cool the electrical chamber 10b2.

[0068] With reference to Figure 5 As shown, the outer shell 11 further includes a bottom bracket 11e connecting the first side plate 11a and the second side plate 11b. The partition wall 12 is provided with a circuit installation hole 12a communicating the battery compartment 10a and the heat exchange chamber 10b1, and a waterway installation hole 12b communicating the battery compartment 10a and the electrical chamber 10b2. The battery cluster 20 further includes a main cable 21 electrically connected to the battery and disposed in the circuit installation hole 12a. The pipeline includes a main liquid pipe 31a communicating with the heat exchange member and disposed in the waterway installation hole 12b. The battery, the main cable 21, and the main liquid pipe 31a are arranged vertically in the battery compartment 10a, and a space is provided between the main liquid pipe 31a and the bottom bracket 11e.

[0069] In this embodiment, the main liquid pipe 31a is fixed on the bottom bracket 11e by a pipe support 11g to achieve a spaced arrangement from the bottom bracket 11e. When excessive condensate is generated in the battery compartment 10a or battery leakage forms a liquid accumulation on the bottom bracket 11e, the pipe support 11g lifts the main liquid pipe 31a above the bottom bracket 11e, avoiding damage to the main liquid pipe 31a caused by the liquid accumulation. The main cable 21 is fixed in the circuit installation hole 12a by a wire splitter 12d and fixed in the battery compartment 10a by a cable support at the bottom of the battery rack, so that the main cable 21 is lifted above the bottom bracket 11e, avoiding damage to the main cable 21 caused by the liquid accumulation.

[0070] Moreover, by arranging the main liquid pipe 31a below the battery and the main cable 21, damage to the battery and the main cable 21 caused by leakage of the main liquid pipe 31a can be avoided. The main cable 21 is spaced above the main liquid pipe 31a, realizing a layered arrangement of the main cable 21 and the main liquid pipe 31a, facilitating the installation of the main cable 21 and the main liquid pipe 31a, and also facilitating the inspection and maintenance of the main cable 21 and the main liquid pipe 31a in the later stage.

[0071] Specifically, the outer shell 11 further includes a top plate 11f connecting the first side plate 11a and the second side plate 11b. In this embodiment, the upper and lower ends of the partition wall 12 and the partition board 15 are both connected to the bottom bracket 11e and the top plate 11f, thereby reducing the gas flow between each compartment or chamber.

[0072] Furthermore, the energy storage container further includes a power distribution cabinet 70 and a fire protection cabinet 80 disposed in the electrical chamber 10b2, and a dehumidifier 90 disposed on the top plate 11f and located in the battery compartment 10a.

[0073] In this embodiment, the power distribution cabinet 70 and the fire cabinet 80 are arranged in the independent electrical room 10b2, which can ensure the stable operation of both and avoid being affected by other cabins or rooms. The box body 10 further includes an electrical side door 10c arranged on the first side plate 11a to open or close the electrical room 10b2. The electrical room 10b2 is opened by the separate electrical side door 10c, which facilitates the later maintenance of the electrical room 10b2. Moreover, the electrical room 10b2 is also equipped with a power distribution control cabinet, monitoring, induction detection equipment, lighting system, emergency lighting system, system emergency start-stop system, etc. The setting of the electrical room 10b2 ensures the normal operation of these electronic instruments.

[0074] Among them, the power distribution cabinet 70 includes an EMU energy management unit, a UPS power supply, a BMS battery management system, power distribution equipment, etc.

[0075] The fire cabinet 80 includes fire cylinders and a fire host. Smoke sensors, temperature sensors, combustible gas detectors, toxic gas detectors and other alarm sensors are arranged in the cabin or room. The internal dangerous information of the cabin or room is received through the alarm sensors. If the information exceeds the predetermined threshold and is judged as dangerous, an alarm message will be sent to the upper computer, and the alarm light and alarm bell will be started for corresponding alarm work, and the gas fire extinguishing device and the water spray fire extinguishing device will be started to extinguish the fire jointly. After the fire cabinet 80 detects a dangerous signal, it controls the electric louvers on the air inlet 13 and the air outlet 14 to open, and controls the driving fan 40 in the air inlet 13 and the air outlet 14 to operate, so as to quickly discharge the toxic gas or combustible gas in the battery compartment 10a and eliminate potential safety hazards.

[0076] A dehumidifier 90 is arranged in the battery compartment 10a, which can reduce the humidity in the battery compartment 10a and reduce the influence of condensed water on the battery cluster 20.

[0077] Furthermore, a fire installation opening 12c communicating the battery compartment 10a and the electrical room 10b2 is provided at the top of the partition wall 12. Continue to refer to Figure 4 As shown, in this embodiment, a channel for installing fire pipes is formed between the fire installation opening 12c and the top wall 11f. After the fire pipes are installed, there is still a certain gap between the fire installation opening 12c and the top wall 11f. At this time, a certain gas flow can be generated between the battery compartment 10a and the electrical room 10b2. In this way, when the exhaust fan 60 extracts the gas in the electrical room 10b2, the gas in the battery compartment 10a can enter the electrical room 10b2 through the fire installation opening 12c. At this time, the dry gas after dehumidification in the battery compartment 10a will enter the electrical room 10b2, thereby drying the electrical room 10b2.

[0078] Of course, in some embodiments, a separate ventilation hole may also be provided on the partition wall 12 to connect the battery compartment 10a and the electrical chamber 10b2, thereby accelerating the gas flow in the electrical chamber 10b2 and accelerating the cooling and drying in the electrical chamber 10b2.

[0079] Specifically, the electrical exhaust port 15c is provided at the top of the second plate 15b, and the dehumidifier 90 and the exhaust fan 60 are oppositely arranged on both sides of the fire protection installation opening 12c. In this embodiment, the dehumidifier 90 is arranged adjacent to the partition wall 12, and the dehumidifier 90, the fire protection installation opening 12c and the exhaust fan 60 are arranged along the length direction of the housing 11, so that the dry gas near the dehumidifier 90 is more easily sucked into the electrical chamber 10b2 by the exhaust fan 60 through the fire protection installation opening 12c. Moreover, since the exhaust fan 60 is arranged at the top of the second plate 15b, it can accelerate the discharge of the hot air at the top of the electrical chamber 10b2 and also accelerate the discharge of the hot air at the top of the heat exchange chamber 10b1.

[0080] Specifically, the box body 10 further includes a heat exchange hole 10d provided on the first side plate 11a and communicating with the heat exchange chamber 10b1, and a battery side door 10e provided on the first side plate 11a and / or the second side plate 11b to open or close the battery compartment 10a. In this embodiment, a ventilation plate covering the end face of the heat exchange chamber 10b1 is provided on the first side plate 11a, and the ventilation plate has a plurality of uniformly arranged heat exchange holes 10d. Battery side doors 10e are provided on both the first side plate 11a and the second side plate 11b, which is convenient for installing and maintaining the battery cluster 20 in the battery compartment 10a.

[0081] During specific operation, with reference to Figure 2 、 Figure 3 and Figure 6 as shown, the gas outside the housing 11 enters the battery compartment 10a from the air inlet 13 under the action of the driving fan 14. Most of the gas in the battery compartment 10a is discharged into the heat exchange chamber 10b1 from the air outlet 14, and this part of the gas is finally discharged outside the housing 11 through the ventilation side door 16. A small part of the gas in the battery compartment 10a is affected by the exhaust fan 60, enters the electrical chamber 10b2 through the fire protection installation opening 12c, enters the heat exchange chamber 10b1 through the exhaust fan 60, and then is discharged outside the housing 11 through the ventilation box door 11d or the heat exchange hole 10d. The liquid cooling unit 30 extracts the gas outside the housing 11 through the liquid cooling air inlet 33 and the heat exchange hole 10d, and discharges it outside the housing 11 from the top of the ventilation box door 11d. The energy storage AC 50 extracts the gas outside the housing 11 through the ventilation box door 11d and discharges it outside the housing 11 through the ventilation side door 16.

[0082] Further, the equipment compartment 10b has a heat exchange chamber 10b1 for accommodating the liquid cooling unit 30 and an electrical chamber 10b2 spaced apart from the heat exchange chamber 10b1. The liquid cooling unit 30 and the battery compartment 10a are oppositely arranged on both sides of the electrical chamber 10b2.

[0083] In this embodiment, by providing the electrical chamber 10b2 spaced apart from the liquid cooling unit 30 in the equipment compartment 10b, the battery compartment 10a and the liquid cooling unit 30 are spaced apart on both sides of the electrical chamber 10b2, reducing the heat exchange between the liquid cooling unit 30 and the battery compartment 10a, thereby reducing the influence of the liquid cooling unit 30 on the internal temperature of the battery compartment 10a and ensuring the liquid cooling effect for the battery.

[0084] Further, the housing 11 includes a first side plate 11a and a second side plate 11b oppositely arranged in the width direction, and end walls 11c and a ventilation box door 11d connecting the first side plate 11a and the second side plate 11b and oppositely arranged. The battery compartment 10a is formed between the partition wall 12, the end wall 11c, the first side plate 11a and the second side plate 11b. The liquid cooling unit 30 is arranged between the ventilation box door 11d and the electrical chamber 10b2.

[0085] In this embodiment, the battery compartment 10a is formed on one side close to the end wall 11c, and the liquid cooling unit 30 is adjacently arranged on one side of the ventilation box door 11d. In this way, the battery compartment 10a and the liquid cooling unit 30 are oppositely arranged at both ends in the length direction of the housing 11, thereby maximizing the distance between the battery compartment 10a and the liquid cooling unit 30 and reducing the heat exchange between the battery compartment 10a and the liquid cooling unit 30.

[0086] Further, the box body 10 further includes a partition plate 15 connecting the partition wall 12 and the first side plate 11a. The electrical chamber 10b2 is formed between the partition wall 12, the partition plate 15 and the first side plate 11a. The electrical chamber 10b2 and the battery compartment 10a are oppositely arranged at both ends of the partition wall 12.

[0087] In this embodiment, the electrical chamber 10b2 and the battery compartment 10a are oppositely arranged at both ends of the partition wall 12, reducing the area of the shared partition wall 12 between the heat exchange chamber 10b1 and the battery compartment 10a, thereby reducing the heat transferred from the liquid cooling unit 30 to the shared partition wall 12 through the internal air of the heat exchange chamber 10b1, so as to reduce the heat transferred to the inside of the battery compartment 10a through this shared partition wall 12.

[0088] Further, the partition plate 15 includes a first plate 15a connecting the partition wall 12 and a second plate 15b connecting the first plate 15a and the first side plate 11a. The liquid cooling unit 30 is arranged between the ventilation box door 11d and the second plate 15b and is located on the side of the first plate 15a away from the second side plate 11b.

[0089] In this embodiment, the first plate 15a is arranged parallel to the first side plate 11a, the second plate 15b is arranged parallel to the end wall 11c, and the first plate 15a and the second plate 15b are perpendicular to each other, so that the heat exchange chamber 10b1 is preferably in an "L" shape, thereby reducing the area of the common partition wall 12 shared by the heat exchange chamber 10b1 and the battery compartment 10a, and at the same time reducing the amount of heat radiated from the liquid cooling unit 30 towards the common partition wall 12 between the heat exchange chamber 10b1 and the battery compartment 10a, that is, the heat generated by the liquid cooling unit 30 is not easily transferred to the battery compartment 10a through the heat exchange chamber 10b1.

[0090] Further, the energy storage container further includes an energy storage converter 50 disposed in the heat exchange chamber 10b1 and opposite to the liquid cooling unit 30 along the width direction of the housing 11, and at least part of the energy storage converter 50 is located between the first plate 15a and the second side plate 11b.

[0091] In this embodiment, as Figure 2 , at least part of the energy storage converter 50 is located between the first plate 15a and the second side plate 11b, which can block the heat transfer from the liquid cooling unit 30 to the battery compartment 10a through the heat exchange chamber 10b1, and reduce the influence of the liquid cooling unit 30 on the internal temperature of the battery compartment 10a.

[0092] Further, the housing 11 further includes a bottom support 11e connecting the first side plate 11a and the second side plate 11b. The partition wall 12 is provided with a circuit installation hole 12a communicating the battery compartment 10a and the heat exchange chamber 10b1, and a water pipe installation hole 12b communicating the battery compartment 10a and the electrical chamber 10b2. The battery cluster 20 further includes a main cable 21 electrically connected to the battery and disposed in the circuit installation hole 12a. The pipeline includes a main liquid pipe 31a communicating with the heat exchange member and disposed in the water pipe installation hole 12b. The battery, the main cable 21, and the main liquid pipe 31a are arranged vertically in the battery compartment 10a, and the main liquid pipe 31a is spaced from the bottom support 11e.

[0093] In this embodiment, as Figure 4 , the main cable 21 is routed from the heat exchange chamber 10b1 and electrically connected to the energy storage converter 50, saving the routing distance of the main cable 21. The main liquid pipe 31a passes through the electrical chamber 10b2 and then communicates with the liquid cooling unit 30, saving the piping distance of the main liquid pipe 31a and also avoiding being affected by the temperature in the heat exchange chamber 10b1. Moreover, since the main cable 21 and the main liquid pipe 31a pass through the two sides of the partition wall 12 respectively and pass through different chambers, the condensate water on the main liquid pipe 31a is prevented from affecting the safe use of the main cable 21, thereby avoiding mutual influence between the main liquid pipe 31a and the main cable 21.

[0094] Further, the housing 11 further includes a top plate 11f connecting the first side plate 11a and the second side plate 11b. The partition 15 further includes an electrical exhaust port 15c provided on the second plate 15b and communicating the electrical chamber 10b2 with the heat exchange chamber 10b1. The energy storage container further includes a power distribution cabinet 70 and a fire protection cabinet 80 provided in the electrical chamber 10b2, a dehumidifier 90 provided on the top plate 11f and located in the battery compartment 10a, and an exhaust fan 60 provided in the electrical exhaust port 15c. The top of the partition wall 12 is provided with a fire protection installation opening 12c communicating the battery compartment 10a with the electrical chamber 10b2, and the waterway installation hole 12b is provided at the bottom of the partition wall 12.

[0095] In this embodiment, the power distribution cabinet 70 and the fire protection cabinet 80 are provided on one side of the electrical chamber 10b2 close to the partition wall 12. The fire protection pipeline is routed from the top of the partition wall 12, and the main liquid pipeline 31a is routed from the bottom of the partition wall 12 to avoid mutual influence between the fire protection pipeline and the main liquid pipeline 31a.

[0096] Further, the partition wall 12 extends along the width direction of the housing 11. The box body 10 further includes an electrical side door 10c provided on the first side plate 11a to open or close the electrical chamber 10b2, a heat exchange hole 10d provided on the first side plate 11a and communicating with the heat exchange chamber 10b1, a breathable side door 16 provided on the second side plate 11b to open or close the heat exchange chamber 10b1, and a battery side door 10e provided on the first side plate 11a and the second side plate 11b to open or close the battery compartment 10a. At least a part of the energy storage converter 50 is located between the breathable side door 16 and the first plate 15a, and the heat exchange hole 10d is exposed towards the liquid cooling unit 30.

[0097] In this embodiment, a ventilation plate covering the end face of the heat exchange chamber 10b1 is provided on the first side plate 11a. The liquid cooling unit 30 is adjacent to and abuts against the ventilation plate and the breathable box door 11d, and the energy storage converter 50 is adjacent to and abuts against the breathable side door 16 and the breathable box door 11d, making reasonable use of the internal space of the heat exchange chamber 10b1 and achieving better heat exchange effect between the heat exchange chamber 10b1 and the outside.

[0098] Further, the dehumidifier 90 is adjacent to the partition wall 12 and is disposed opposite to the fire protection installation opening 12c. In this embodiment, since the dehumidifier 90 is disposed opposite to the fire protection installation opening 12c, the dry gas around the dehumidifier 90 is more easily sucked into the electrical chamber 10b2 by the exhaust fan 60 through the fire protection installation opening 12c, preventing the humid air inside the battery compartment 10a from entering the electrical chamber 10b2, and at the same time drying the inside of the electrical chamber 10b2 to ensure the normal operation of the equipment inside the electrical chamber 10b2.

[0099] Reference Figures 7 to 13As shown, another preferred embodiment of the present invention provides an energy storage container. Compared with the energy storage container in the above embodiment, the energy storage container further includes a support device 100 connected to the bottom of the box body 10, which can increase the installation strength of the box body 10 and can also collect the condensed water or battery waste liquid discharged from the energy storage container, avoiding environmental pollution.

[0100] With reference to Figure 7 As shown, specifically, the energy storage container further includes a support device 100 connected to the bottom of the box body 10. In this embodiment, the support device 100 is connected to the box body 10 and supports the bottom of the box body 10, so that there is no need to pour cement to raise the foundation, and the strength of the box body 10 is enhanced, and the deformation of the box body 10 is reduced.

[0101] With reference to Figure 8 As shown, further, the support device 100 includes a support platform 101 matching the bottom support 11e and a liquid collecting member 103 connecting the support platform 101. The support platform 101 has an installation channel 101a exposed towards the bottom support 11e, and the liquid collecting member 103 is arranged in the installation channel 101a and at least partially located below the battery compartment 10a.

[0102] In this embodiment, the support platform 101 has a hollow installation channel 101a, providing an installation space for the liquid collecting member 103. On the one hand, it ensures the structural strength of the support platform 101, and on the other hand, it makes it impossible for users to observe the liquid collecting member 103 from the outside of the support platform 101, avoiding users from contacting the waste liquid in the liquid collecting member 103 and eliminating potential safety hazards. The liquid collecting member 103 at least covers the area below the battery compartment 10a, because there is very little waste liquid generated in the equipment compartment 10b, which can save the manufacturing cost of the liquid collecting member 103.

[0103] The support device 100 uses the liquid collecting member 103 provided on the support platform 101 to collect the battery waste liquid discharged from the energy storage container, which can avoid environmental pollution caused by the direct discharge of the battery waste liquid outside the box body 10.

[0104] Of course, the support device 100 in this embodiment is not only applicable to the energy storage container using the liquid cooling method in the above embodiment, that is, the liquid collecting member 103 is used to collect condensed water and battery waste liquid, but also applicable to the energy storage container using only the air cooling method, that is, the liquid collecting member 103 is used to collect the battery waste liquid generated in the battery compartment 10a.

[0105] Specifically, the liquid collecting member 103 includes a bottom wall 103a, side walls 103b connected to the periphery of the bottom wall 103a and extending towards the bottom support 11e, and an opening 103c formed by surrounding the upper side edges of the side walls 103b. The opening 103c is located below the battery compartment 10a.

[0106] In this embodiment, the liquid collecting member 103 is configured as a dish-shaped structure with an upward opening and is disposed below the battery compartment 10a. The condensed water or battery waste liquid in the battery compartment 10a falls into the liquid collecting member 103 under the action of gravity, facilitating the collection of the waste liquid. Moreover, when the condensed water in the battery compartment 10a falls into the liquid collecting member 103, due to the large area of the bottom wall 103a, the condensed water will quickly evaporate, preventing accumulation in the liquid collecting member 103.

[0107] Specifically, one or more floor drains communicating with the battery compartment 10a are provided on the bottom tray 11e to downwardly introduce the liquid in the battery compartment 10a into the opening 103c. At this time, the bottom wall 103a only needs to cover below one or more floor drains. In this way, the liquid collecting member 103 is applicable to more types of energy storage containers, and only the size of the bottom wall 103a needs to be adjusted according to the number of floor drains.

[0108] Of course, in some embodiments, the floor drain and the liquid collecting member 103 can also be connected through a liquid guiding pipe, so as to directly introduce the accumulated liquid into the liquid collecting member 103, which is more conducive to environmental protection.

[0109] In addition, in this embodiment, the number of the liquid collecting members 103 is preferably one. When the user maintains the energy storage container, only the waste liquid in a single liquid collecting member 103 needs to be processed to complete the waste liquid treatment work.

[0110] Of course, in some embodiments, the number of the liquid collecting members 103 can also be multiple, and the multiple liquid collecting members 103 are matched with multiple floor drains, thereby saving the manufacturing cost of a single liquid collecting member 103.

[0111] Furthermore, the bottom wall 103a is inclined with respect to the horizontal plane. In this embodiment, the inclination angle of the bottom wall 103a with respect to the horizontal plane is preferably 5°. The liquid falling on the bottom wall 103a will flow towards the lower horizontal height of the bottom wall 103a under the action of gravity. During the flowing process, the evaporation of the condensed water is accelerated, causing the liquid in the liquid collecting member 103 to concentrate on one side, facilitating the user to collect the liquid in the liquid collecting member 103 later and preventing the liquid from remaining in the liquid collecting member 103.

[0112] With reference to Figure 9 As shown, further, the liquid collecting member 103 further includes a drain valve 103d provided on the bottom wall 103a, and the drain valve 103d is provided at the lower horizontal height of the bottom wall 103a. In this embodiment, the drain valve 103d is provided at the bottom of the bottom wall 103a and on the lower horizontal height side of the bottom wall 103a, facilitating the user to collect the liquid in the liquid collecting member 103 later and facilitating the discharge of the liquid in the liquid collecting member 103.

[0113] With reference to Figure 10 and Figure 11As shown, further, the box body 10 further includes corner fittings 17 connected to the bottom support 11e. The corner fittings 17 have a corner bottom plate 17a at the bottom and corner positioning holes 17b provided on the corner bottom plate 17a. The support device 100 further includes an installation structure 105 connecting the support platform 101 and the corner fittings 17. The installation structure 105 includes an installation plate 105a connecting the support platform 101 and a limiting member 105b connecting the installation plate 105a and matching the corner positioning holes 17b. When the corner bottom plate 17a abuts against the installation plate 105a, the limiting member 105b is located in the corner positioning holes 17b and at least partially protrudes from the upper surface of the installation plate 105a.

[0114] In this embodiment, the support device 100 includes four installation structures 105 connected to the four corner fittings 17 of the box body 10. The gravity exerted on the box body 10 causes the corner bottom plate 17a of the corner fittings 17 to abut against the installation plate 105a of the installation structure 105, keeping the box body 10 horizontally placed. Of course, later, leveling can also be performed by setting gaskets between the corner bottom plate 17a and the installation plate 105a.

[0115] After the corner fittings 17 and the installation structure 105 are cooperatively installed, after the limiting member 105b is matched and set in the corner positioning holes 17b, it restricts the horizontal offset between the corner fittings 17 and the installation structure 105, ensuring the stability of the position between the box body 10 and the support device 100, and the cooperation is convenient, facilitating the installation of the box body 10 and the support device 100.

[0116] Further, the corner fittings 17 further have corner side plates 17c connected to the periphery of the corner bottom plate 17a and corner limiting holes 17d provided on the corner side plates 17c. The installation structure 105 further includes locking holes 105c provided on the limiting member 105b, positioning members 105d connecting the installation plate 105a and matching the corner side plates 17c, connection holes 105e provided on the positioning members 105d, and fixing members 105f connecting the locking holes 105c and located in the connection holes 105e. The central axis of the locking holes 105c and the central axis of the connection holes 105e are collinear with each other. When the corner bottom plate 17a abuts against the installation plate 105a, the fixing member 105f is at least partially located in the corner limiting holes 17d.

[0117] In this embodiment, after the corner fittings 17 and the installation structure 105 are cooperatively installed, since the fixing member 105f is located in the corner limiting holes 17d, it restricts the upward detachment of the corner fittings 17 from the installation structure 105, avoiding the mutual detachment between the box body 10 and the support device 100, and ensuring the connection strength between the box body 10 and the support device 100.

[0118] Of course, in some embodiments, the corner fittings 17 and the installation structure 105 can also be fixed together by welding.

[0119] Specifically, the positioning member 105d includes a first positioning plate 105d1 and a second positioning plate 105d2 that are connected to the mounting plate 105a and are perpendicular to each other, a first guiding plate 105d3 connected to the top of the first positioning plate 105d1, and a second guiding plate 105d4 connected to the top of the second positioning plate 105d2. The first guiding plate 105d3 is inclined upward from the end connected to the first positioning plate 105d1 and in a direction away from the limiting block 105b, and the second guiding plate 105d4 is inclined upward from the end connected to the second positioning plate 105d2 and in a direction away from the limiting block 105b.

[0120] In this embodiment, as Figure 5 , when the corner fitting 17 is vertically downward and cooperates with the mounting structure 105, the first guiding plate 105d3 and the second guiding plate 105d4 of the positioning member 105d are used to guide the side wall of the corner side plate 17c, so that the corner side plate 17c can more easily enter the side close to the limiting block 105b of the first positioning plate 105d1 and the second positioning plate 105d2, which is convenient for the fitting and installation between the box body 10 and the support device 100.

[0121] Specifically, the limiting member 105b includes a first limiting block 105b1 that is connected to the mounting plate 105a and forms a locking hole 105c, and a second limiting block 105b2 that is connected to the mounting plate 105a and is spaced from the first limiting block 105b1. The first limiting block 105b1 and the second limiting block 105b2 are arranged along the central axis direction of the locking hole 105c.

[0122] In this embodiment, the limiting member 105b is provided with two spaced-apart first limiting blocks 105b1 and second limiting blocks 105b2. On the one hand, it does not affect the limiting strength between the limiting member 105b and the corner positioning hole 17b. On the other hand, during the positioning cooperation between the corner positioning hole 17b and the limiting member 105b, due to the reduction of the side area of the limiting member 105b, the contact area between the corner positioning hole 17b and the side of the limiting member 105b is reduced, which is more convenient for the positioning cooperation between the corner positioning hole 17b and the limiting member 105b.

[0123] Specifically, the support platform 101 includes a cross beam 101b and a longitudinal beam 101c that are connected to each other to enclose an installation channel 101a. In this embodiment, as Figure 8 , the support platform 101 is fixed by two cross beams 101b and two longitudinal beams 101c, which is convenient for the manufacture and assembly of the support platform 101. The cross beam 101b and the longitudinal beam 101c can be fixedly connected by bolts or by welding.

[0124] With reference to Figure 12 andFigure 13 As shown, further, the cross beam 101b and / or the longitudinal beam 101c include a plurality of connecting beams 101d and connecting pairs 101e connected between adjacent connecting beams 101d. The connecting pairs 101e are detachably connected to the connecting beams 101d.

[0125] In this embodiment, the longitudinal beam 101c with a longer length can be assembled in a segmented manner, that is, it is formed by fixedly connecting a plurality of connecting beams 101d. This method can disassemble the longitudinal beam 101c with a longer length for transportation and then assemble it on site, thus facilitating the transportation of the support device 100.

[0126] Specifically, as Figure 13 , the connecting pair 101e includes a plurality of connecting plates 101e1 attached to the connecting beam 101d and a plurality of bolt members 101e2 connecting the connecting beam 101d and the connecting plates 101e1. The plurality of bolt members 101e2 are evenly arranged to prevent the shear force on the longitudinal beam 101c from concentrating. Among them, the connecting beam 101d is made of H-shaped steel. Of course, it can also be made of I-shaped steel or channel steel.

[0127] Further, the support device 100 further includes a plurality of support columns 107 connected to the support platform 101 and stepped platforms 109 connected to the support platform 101 and oppositely arranged on both sides of the support platform 101. In this embodiment, the setting of the plurality of support columns 107 increases the installation height of the box body 10, so that the use requirements can be met without pouring cement heightening pads.
