DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0046] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms “mounting” and “connection” should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] See Figures 1 to 5 As shown in the figure, this application provides a sodium-ion battery energy storage container, including a container 1, multiple partition walls 2, multiple clusters 3, multiple air conditioning systems 4, a fire cabinet 51, a power distribution cabinet 52, and a junction box 53. The container 1 has a cavity, and each of the partition walls 2 is disposed within the cavity. The partition walls 2 are arranged sequentially at intervals along the length of the container 1, dividing the cavity into multiple sub-cavities 101. Each cluster 3 is disposed within a corresponding sub-cavity 101, and a sodium-ion battery pack is disposed on each cluster 3. Each cluster 3 has an air duct shell 6 on its top. Each of the air conditioning systems 4 is disposed within the container 1, with the cold air vent of each air conditioning system 4 connected to the corresponding air duct shell 6, and the return air vent of each air conditioning system 4 connected to the corresponding sub-cavity 101. The fire cabinet 51, power distribution cabinet 52, and junction box 53 are all disposed within a sub-cavity 101 at the end of the container 1. The sodium-ion battery energy storage container of this application is equipped with a sodium-ion battery pack. Sodium-ion batteries replace lithium-ion batteries with sodium ions. Sodium is more abundant on Earth, has lower costs, and better safety. Furthermore, sodium ions can generate higher temperatures during discharge, making them well-suited for low-temperature environments and more stable in low-temperature conditions. Therefore, using a sodium-ion battery energy storage container as an energy storage method is a way to ensure stable operation while reducing costs.

[0048] Furthermore, sodium-ion battery energy storage containers often need to be used in environments with normal or high temperatures. In such environments, cooling of the sodium-ion battery packs is necessary to ensure a safe and suitable operating environment. This application's sodium-ion battery energy storage container addresses the significant heat generation during the discharge process by placing the sodium-ion battery packs within multiple sub-cavities 101. Each sub-cavity 101 is equipped with multiple air conditioning systems 4, and cooling gas is introduced into each sub-cavity 101 through corresponding air duct shells 6. Each cluster 3 corresponds to one air conditioner and one air outlet 141, ensuring that all sodium-ion battery packs within the container 1 are close to the air-cooled air conditioning outlet 141, receiving low-temperature cold air for better cooling. The multiple sub-cavities 101 receive the cooling air separately, resulting in uniform heat exchange throughout the entire cavity. This ensures that the operational stability and lifespan of each sodium-ion battery pack are not significantly different, thereby guaranteeing excellent operational stability of the entire sodium-ion battery energy storage container. Furthermore, the partition walls separate different battery clusters, dividing a large battery compartment into several smaller battery compartments, which also helps to prevent the rapid spread of fire in the event of a fire.

[0049] In some possible embodiments, the container 1 has a top plate 11, a bottom frame 12, two side plates 13 and two end plates. The two side plates 13 are respectively arranged on the two length edges of the bottom frame 12, and the two end plates are respectively arranged on the two width edges of the bottom frame 12. The end plates are connected to the two side plates 13, and the air conditioning systems 4 are arranged on the two side plates 13. The air conditioning systems 4 are arranged in sequence and at intervals along the length direction of the side plates 13. The top plate 11, the bottom frame 12, the two side plates 13 and the two end plates form a closed cavity, and the circulating cold air of the air conditioning systems 4 circulates in the cavity. In a high-temperature environment, the loss of cold air can be reduced, thereby reducing energy consumption. Furthermore, the sub-cavities 101 are arranged in sequence along the side plates 13, and the air conditioning systems 4 are arranged on the side plates 13, which are arranged at positions closest to the sub-cavities 101. In this way, each air conditioning system 4 communicates with each sub-cavity 101 without a long air duct shell 6. First, the loss of cold energy during the transmission of cold air can be reduced, thereby further reducing energy consumption. Second, the use of materials is also reduced, thereby reducing the overall cost. Third, the space utilization is improved. Furthermore, the air conditioning systems 4 are arranged on the two side plates 13 to supply cold air into the cavity from both sides. The double heat exchange intensity of the battery pack is improved, the sodium-ion battery pack can stably operate in the container 1, and the influence of the failure of an individual air conditioning system 4 on the operation of the sodium-ion battery energy storage container is also reduced.

[0050] In some possible embodiments, two cluster frames 3 are arranged in at least part of the sub-cavities 101 in the sodium-ion battery energy storage container. The two cluster frames 3 are arranged in sequence along the width direction of the bottom frame 12, and each air conditioning system 4 on the two side plates 13 corresponds to the opposite air conditioning system 4, which communicates with the same sub-cavity 101. The cluster frames 3 in the sub-cavities 101 are arranged in pairs, and the two cluster frames 3 in the same pair are arranged side by side, and the space arrangement is reasonable. The cluster frames 3 arranged in pairs are arranged on the air duct shell 6, and the air duct shell 6 is arranged on one side of the cluster frame 3 close to the side plate 13. The air conditioning systems 4 on the two side plates 13 correspond to the cluster frames 3 arranged side by side from both sides, respectively, and communicate with each cluster frame 3 through the air duct shell 6. Each cluster frame 3 corresponds to one air conditioning system 4, and does not need to pass through other cluster frames 3 for cooling, thereby ensuring that each cluster frame 3 achieves the best cooling effect.

[0051] In some possible embodiments, one of the two end plates is the front end plate 14 and the other is the rear end plate 15. The front end plate 14 is provided with an air outlet 141 and a fan located on the air outlet 141, and the side plate 13 away from the front end plate 14 is provided with an air inlet 131. During the use of sodium-ion batteries, some gas is generated, and when the concentration reaches a certain level, the cavity needs to be ventilated. During the ventilation of the cavity, air enters from the air inlet 131 and exits from the air outlet 141. The air inlet 131 and the air outlet 141 are separately arranged at the front and rear ends of the container 1, and the air path extends from one end of the container 1 to the other end, so as to avoid the position in the cavity that is not easy to be ventilated. The main function of the fan is to ensure that the combustible gas in the container 1 can be smoothly discharged. When the multi-in-one detector 10 detects that the combustible gas reaches the alarm threshold, the exhaust fan needs to be started to discharge the combustible gas with too high concentration in the container.

[0052] Preferably, the air outlet 141 is arranged on the side of the front end plate 14 away from the side plate 13 provided with the air inlet 131. In this way, it is ensured that the dead angle that is not easy to be ventilated appears in the width direction.

[0053] Further, two air outlets 141 are arranged on the upper end, one of which is arranged close to the top plate 11, and the other of which is arranged close to the bottom plate 123. In this way, during the ventilation of the cavity, two fans can simultaneously draw air, the air exhaust volume is large, the air flow rate in the cavity is high, the ventilation process is less likely to produce a dead angle, and the ventilation effect is better.

[0054] Further, the front end plate 14 is further provided with a pressure relief port 142. The function of the pressure relief port 142 is to ensure that the pressure in the container 1 is not too large when the fire-fighting gas is sprayed. If the internal pressure is too large, the pressure relief port 142 can discharge excess gas, thereby reducing the internal pressure of the container 1 and reducing the possibility of explosion.

[0055] In some possible embodiments, the container 1 is provided with a plurality of shielding covers 7, and each shielding cover 7 is located at the top of the pressure relief port 142, the air inlet 131, and the air outlet 141. The shielding cover 7 is located outside the container 1, and the shielding cover 7 can block rainwater or dust from entering the cavity through the pressure relief port 142, the air inlet 131, and the air outlet 141, thereby affecting the operation of the sodium-ion battery. However, the shielding cover 7 does not affect the communication between the pressure relief port 142, the air inlet 131, and the air outlet 141 and the outside.

[0056] In some possible embodiments, each of the partition plates 2 is provided with an avoiding port 21, and the avoiding port 21 communicates two adjacent sub-cavities 101. The avoiding port 21 communicates each of the sub-cavities 101, so that the air in each of the sub-cavities 101 can flow to the air outlet 141 through the avoiding port 21 during ventilation.

[0057] In some possible embodiments, the base frame 12 has a base plate 123, a plurality of cluster frame 3 support beams 121 arranged on the base plate 123, and side beams 122 arranged on the base plate 123 on both sides of each cluster frame 3 support beam 121. The height of the cluster frame 3 support beam 121 is higher than the base plate 123, and the height of the cluster frame 3 support beam 121 is higher than the side beam 122, and the cluster frame 3 is supported on the cluster frame 3 support beam 121. The cluster frame 3 is transferred by a forklift when placed on the base frame 12, and the support beam can facilitate the forklift operation when the cluster frame 3 is installed. If there is no cluster frame 3 support beam 121 when the forklift forks into the cluster frame 3 in the container, the forklift will interfere with the base plate 123 of the container 1, and the cluster frame 3 will also be greatly jolted when the cluster frame 3 is placed. In addition, the support beam also facilitates the welding of the cluster frame 3 at the back during installation, or the pre-buried nut for fixing the cluster frame 3. Preferably, four support beams are included, which are arranged in parallel with the side plates 13 at intervals, and each cluster frame 3 is arranged on two support beams, so that the stability of the cluster frame 3 can be ensured and the cluster frame 3 is not easily inclined.

[0058] In some possible embodiments, the base frame 12 is provided with a wiring pipe 8 on both sides in the width direction, and the power supply lines and communication lines of the sodium-ion battery energy storage container are at least partially located in the wiring pipe 8 and extend along the wiring pipe 8. The power supply lines and communication lines are clear when wired along the wiring pipe 8 and are not easy to entangle, and the wiring pipe 8 can also protect the internal cables and prevent the cables from being damaged due to pressure. Among them, the power supply lines and communication lines connect each sodium-ion battery pack and each air conditioning system 4, and finally converge to the power distribution cabinet 52 and the busbar cabinet 53.

[0059] Further, the wiring pipe 8 includes a first line pipe 81 and a second line pipe 82, and the power supply lines are partially located in the first line pipe 81 and the communication lines are partially located in the second line pipe 82. Different types of lines are wired in pipes, which are not easy to confuse and are convenient for connection and maintenance.

[0060] In some possible embodiments, the sodium-ion battery energy storage container includes a fire-fighting water pipe 9, which extends along the length direction of the container 1, and the fire-fighting water pipe 9 sequentially passes through each sub-cavity 101, and the fire-fighting water pipe 9 is provided with a water outlet on the pipe segment located in each sub-cavity 101. If the sodium-ion battery pack in the container 1 appears a thermal runaway situation, water can be sprayed into the cavity through the fire-fighting water pipe 9 to control the thermal runaway phenomenon. The fire-fighting water pipe 9 extends along the top plate 11 of the container 1 through the avoiding opening 21.

[0061] In some possible embodiments, the multi-in-one detector 10 for detecting hydrogen and carbon monoxide content is arranged in the sub-cavity 101 containing the cluster rack 3. The temperature sensor and the smoke sensor are also arranged in the sub-cavity 101 containing the fire-fighting cabinet 51, the power distribution cabinet 52 and the busbar cabinet 53. When the multi-in-one detector 10 detects that the combustible gas reaches the alarm threshold, the exhaust fan needs to be started to exhaust the combustible gas with too high concentration in the box. The fire-fighting cabinet 51, the power distribution cabinet 52 and the busbar cabinet 53 can collect the information of the multi-in-one detector 10, the temperature sensor and the smoke sensor and make logical judgment to start the fire-fighting in stages, and upload the alarm information to the station-level host computer.

[0062] In some possible embodiments, the perfluorocyclohexanone gas fire-fighting cabinet 5451 for storing the perfluorocyclohexanone gas fire-fighting agent is also arranged in the sub-cavity 101 containing the fire-fighting cabinet 51, the power distribution cabinet 52 and the busbar cabinet 53. When the fire occurs inside the container 1, the perfluorocyclohexanone gas can be input into each sub-cavity 101 to play a role in extinguishing the fire and suppressing the fire.

[0063] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the above has disclosed the preferred embodiment of the present application, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and the equivalent embodiments with equivalent changes are equivalent. Any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the present application.
