[0030] The core of the present application lies in providing an explosion vent device to improve the flexibility of the installation position of the explosion vent device.

[0031] Another core of the present application lies in providing an energy storage cabinet with the above-mentioned explosion vent device.

[0032] Another core of the present application lies in providing an energy storage system with the above-mentioned energy storage cabinet.

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0034] With the rapid development of the energy storage industry, the demand for electrochemical energy storage is increasing, the market application scope is constantly expanding, and the safety of electrochemical energy storage has also become a focus issue in the industry. When the energy storage battery cells experience thermal runaway, a large amount of flammable gas will be generated. As the concentration of the flammable gas rises, there will be a risk of combustion and explosion in the energy storage cabinet, which may cause property losses and personal injuries.

[0035] To reduce the damage caused by the explosion of the energy storage cabinet, installing an explosion venting device on the energy storage cabinet can effectively conduct directional pressure relief during an explosion and reduce the damage caused by the explosion. Traditional explosion venting devices used in the energy storage industry are usually composed of explosion venting plates, and the explosion venting plates are all of a single discharge channel type, resulting in relatively large sizes of the explosion venting plates. Moreover, when the explosion venting plate operates, there should be no obstruction in the fan-shaped area where the explosion venting plate needs to open, so that the explosion venting device can generally only be installed on the top or side wall of the energy storage cabinet body, resulting in limitations in the installation position of the explosion venting device and being unable to meet the higher layout requirements of the energy storage cabinet system.

[0036] For this reason, as Figure 1 shown, an embodiment of the present application discloses an explosion venting device 100, which includes an explosion venting plate 102. Multiple discharge channels 101 are formed through rupture disks 1021 to discharge the explosion pressure, so as to ensure that the space required when the discharge channels 101 are opened is reduced under the condition of a certain explosion venting area, enabling the explosion venting device 100 to be installed on the top, side, back or other areas of the energy storage cabinet 200, and improving the flexibility of the installation position of the explosion venting device 100.

[0037] Next, the explosion venting device 100 disclosed in the embodiments of the present application will be specifically explained and described in conjunction with Figures 1 to 4 this.

[0038] As Figures 1 to 4 shown, a plurality of rupture disks 1021 are provided on the explosion venting plate 102 of the explosion venting device 100. The number of rupture disks 1021 can be two, three, four or more. When the preset explosion venting pressure is reached, some or all of the rupture disks 1021 can be opened towards the pressure relief direction to form a plurality of discharge channels 101 corresponding to the rupture disks 1021, so as to achieve directional pressure relief and reduce the damage caused by the explosion. The number of discharge channels 101 should be the same as the number of opened rupture disks 1021, and the number of discharge channels 101 can be two, three, four or more. Thus, when the energy storage cabinet 200 explodes, multiple rupture disks 1021 can be opened towards the pressure relief direction simultaneously to discharge the explosion pressure through the plurality of discharge channels 101 formed by the rupture disks 1021, so as to ensure that the space required when the discharge channels 101 are opened is reduced under the condition of a certain explosion venting area, reduce the space requirement for the opening of the explosion venting plate 102, enable the explosion venting device 100 to be installed on the top, side, back or other areas of the energy storage cabinet 200, improve the flexibility of the installation position of the explosion venting device 100, and thus meet the higher layout requirements of the energy storage cabinet system.

[0039] It should be noted that the preset bursting pressure is the pressure value at which the rupture disk 1021 can be burst open. The magnitude of the preset bursting pressure is related to the ease of bursting open of the rupture disk 1021 and the magnitude of the ambient pressure outside energy storage devices such as the energy storage cabinet 200. The pressure relief direction refers to the direction of releasing the medium from the area with a larger pressure to the area with a smaller pressure. The pressure relief direction here for the energy storage cabinet 200 refers to the direction in which the explosion pressure is released from the inside of the energy storage cabinet 200 to the outside of the energy storage cabinet 200.

[0040] When the bursting area is fixed, the more the number of the pressure relief channels 101 of the pressure relief device 100, the higher the pressure relief efficiency, the smaller the damage caused by the explosion, and at the same time, the smaller the space required when the pressure relief channel 101 is opened, but the larger the occupied space when the pressure relief device 100 is installed.

[0041] To meet the higher layout requirements of the energy storage device, such as Figure 3 and Figure 4 as shown, in some embodiments, when the number of rupture disks 1021 is two or more, a coaxial arrangement as shown in Figure 3 can be adopted. Of course, when the number of rupture disks 1021 is more than two, such as four, an array arrangement as shown in Figure 4 can also be adopted. And to avoid the mutual influence when the rupture disks 1021 open towards the pressure relief direction, the rupture disks 1021 in the array arrangement can adopt an opening method of splitting in half, that is, when the preset bursting pressure is reached, the rupture disks 1021 in adjacent two rows open towards opposite directions. The specific arrangement method can be determined according to the use space of the energy storage device. When the space of the energy storage device is limited in one direction, the pressure relief device 100 can adopt a coaxial arrangement of each rupture disk 1021 to reduce the occupied space of the pressure relief device 100 in this direction. When the space of the device is limited in each direction to a certain extent, the pressure relief device 100 can adopt an array arrangement to reduce the occupied space of the pressure relief device 100 in each direction.

[0042] The main function of the energy storage device is to store energy when the energy supply is excessive and release energy during peak demand. To ensure the minimum loss of energy during storage and release, the heat loss of the energy storage device should be minimized as much as possible. Therefore, the pressure relief device 100 should ensure good sealing at the connection position between the rupture disk 1021 and the pressure relief plate 102 to avoid the heat of the energy storage device from leaking out at the connection position between the rupture disk 1021 and the pressure relief plate 102.

[0043] To ensure the sealing of the pressure relief device 100 while making the rupture disk 1021 easier to open during an explosion, thereby improving the pressure relief efficiency, as shown in Figure 3 and Figure 4As shown, in some embodiments, a weakening seam 1022 and a connecting seam 1023 may be provided at the connection position between the rupture disc 1021 and the pressure relief plate 102, so that when the preset pressure relief pressure is reached, the rupture disc 1021 can flip along the connecting seam 1023 towards the pressure relief direction, thereby achieving the purpose of directional pressure relief. Among them, the weakening seam 1022 can be formed by thinning treatment at the connection position between the rupture disc 1021 and the pressure relief plate 102, or can be formed by indentation, so that the rupture disc 1021 is more likely to crack at the position of the weakening seam 1022. While ensuring good sealing at the connection position between the rupture disc 1021 and the pressure relief plate 102, the opening rate of the rupture disc 1021 during explosion is increased, so that the explosion pressure can be released more quickly, reducing the damage caused by the explosion. In addition, a connecting seam 1023 is provided at the connection position between the rupture disc 1021 and the pressure relief plate 102, which can prevent the rupture disc 1021 from detaching under the impact force generated by the explosion, causing secondary damage to the energy storage device and personnel.

[0044] Among them, the weakening seam 1022 and the connecting seam 1023 enclose a closed figure, and when the number of the connecting seam 1023 and the weakening seam 1022 is certain, the longer the length of the connecting seam 1023, the shorter the length of the weakening seam 1022, the slower the opening rate of the rupture disc 1021 during explosion, but the lower the risk of the rupture disc 1021 detaching under the impact force generated by the explosion. Similarly, when the lengths of the connecting seam 1023 and the weakening seam 1022 are certain, the more the number of the connecting seam 1023, the fewer the number of the weakening seam 1022, the slower the opening rate of the rupture disc 1021 during explosion, but the lower the risk of the rupture disc 1021 detaching under the impact force generated by the explosion.

[0045] As Figures 1 to 4 shown, in some embodiments, the shape of the rupture disc 1021 can be but is not limited to a polygon, and the connecting seam 1023 can be located at any side position of the rupture disc 1021. The rupture disc 1021 can be rectangular, pentagonal, hexagonal, etc. Hereinafter, only the case where the rupture disc 1021 is rectangular will be taken as an example for explanation and illustration. The implementation manners where the rupture disc 1021 is other polygons are similar and will not be elaborated herein. When the rupture disc 1021 is rectangular, a connecting seam 1023 is provided at any side position of the rupture disc 1021, and weakening seams 1022 are provided at the positions of the other three sides, so that when the preset pressure relief pressure is reached, the rupture disc 1021 can flip along the connecting seam 1023 towards the pressure relief direction, thereby achieving the purpose of directional pressure relief. At the same time, the preset pressure relief pressure required to open the rupture disc 1021 can be reduced, while ensuring the opening rate of the rupture disc 1021, avoiding the problem of the rupture disc 1021 detaching under the impact force generated by the explosion.

[0046] Further, as Figure 3As shown, when the rupture disks 1021 are coaxially arranged, the connecting seam 1023 is arranged on the same side of each rupture disk 1021 to prevent mutual influence when each rupture disk 1021 opens; as Figure 4 shown, when the discharge channels 101 are arranged in an array, the connecting seam 1023 is arranged on the opposite sides of the rupture disks 1021 in adjacent rows, that is, an opening method of split opening is adopted to prevent mutual influence when the rupture disks 1021 in adjacent rows open.

[0047] In some other embodiments, the shape of the rupture disk 1021 can also be circular. The connecting seam 1023 is located in the circumferential direction of the rupture disk 1021, and the weakening seam 1022 is also located in the circumferential direction of the rupture disk 1021, so that the connecting seam 1023 and the weakening seam 1022 enclose to form a circular connection boundary between the entire rupture disk 1021 and the explosion vent plate 102. The arc length of the weakening seam 1022 in the circumferential direction of the rupture disk 1021 will directly affect the opening rate of the rupture disk 1021 during explosion. The specific principle is similar to that of the rupture disk 1021 with a polygonal shape in the above embodiments, and will not be elaborated herein.

[0048] In some embodiments, as Figure 3 and Figure 4 shown, the explosion vent plate 102 includes a plurality of rupture disks 1021, that is, the explosion vent plate 102 and the plurality of rupture disks 1021 can adopt an integral structure, so that the explosion vent device 100 has a more compact structure, fewer sealing positions, saves costs, and has higher reliability. By respectively forming the weakening seam 1022 and the connecting seam 1023 in some areas on the explosion vent plate 102, the weakening seam 1022 and the connecting seam 1023 enclose to form the rupture disk 1021, so that when the preset explosion vent pressure is reached, the rupture disk 1021 can crack at the weakening seam 1022 and flip along the connecting seam 1023 towards the pressure relief direction, thereby achieving the purpose of directional pressure relief.

[0049] In some other embodiments, the explosion vent plate 102 and the rupture disk 1021 can also adopt a split structure. By prefabricating a plurality of discharge channels 101 on the explosion vent plate 102, the rupture disks 1021 are hermetically connected to the positions of the discharge channels 101, and each rupture disk 1021 can be independently arranged. When one of the rupture disks 1021 is damaged, it is convenient to replace the damaged rupture disk 1021. At the same time, the weakening seam 1022 and the connecting seam 1023 are respectively formed at the connection positions between the rupture disk 1021 and the explosion vent plate 102, so that when the preset explosion vent pressure is reached, the rupture disk 1021 can crack at the weakening seam 1022 and flip along the connecting seam 1023 towards the pressure relief direction, thereby achieving the purpose of directional pressure relief.

[0050] In order to reduce the heat loss of the energy storage device and ensure that multiple rupture disks 1021 can be torn open along the position of the preset weakening seam 1022 during an explosion, as Figure 1 and Figure 2 shown, sealing members 103 and flanges 104 for pressing the rupture disks 1021 are respectively arranged on both sides of the pressure relief plate 102 in the pressure relief direction. At the same time, windows 105 corresponding to the rupture disks 1021 one by one are respectively arranged on the sealing members 103 and the flanges 104 to ensure that each rupture disk 1021 can be opened smoothly.

[0051] In some embodiments, the sealing member 103 can be made of silica gel material, foaming material or a sealing material with a certain deformation characteristic to achieve sealing, and is connected and fixed to the pressure relief plate 102. Among them, the pressure relief plate 102 and the sealing member 103 can be fixed by means of back glue, encapsulation or fasteners, and the present application does not limit this here. Through the sealing member 103, not only can the sealing protection between the pressure relief device 100 and the energy storage device during installation be achieved, but also the sealing at the weakening seam 1022 of the rupture disk 1021 can be ensured.

[0052] In some embodiments, the flange 104 can be of an integral type or a split type composed of multiple pressure bars, and the flange 104, the pressure relief plate 102 and the sealing member 103 can be fastened by means of buckles, screws or other fasteners. Through the pressing action of the flange 104 on the edge of the rupture disk 1021, the rupture disk 1021 can be torn open along the position of the predetermined weakening seam 1022 during an explosion.

[0053] In order to reduce the heat exchange between the inside and the outside of the energy storage device, as Figure 1 and Figure 2 shown, a heat preservation member 106 is arranged on the rupture disk 1021 to ensure the minimization of energy loss during the storage and release processes.

[0054] In some embodiments, the heat preservation member 106 can be made of inorganic materials such as rock wool, slag wool, glass wool or foam glass. While having heat preservation and heat insulation effects, it can also have a good flame retardant effect. At the same time, the heat preservation member 106 can be bonded to any side of the rupture disk 1021, or can be arranged on both sides of the rupture disk 1021 at the same time, so as to achieve a better heat preservation and heat insulation effect. During an explosion, the rupture disk 1021 and the heat preservation member 106 will open together towards the pressure relief direction. Of course, the heat preservation member 106 can also be fixed to the rupture disk 1021 by means of fasteners such as rivets, and this will not be elaborated here.

[0055] As Figure 5 and Figure 6As shown in the figure, the embodiment of the present application also discloses an energy storage cabinet 200, which includes a cabinet body 201 and an explosion venting device arranged on the cabinet body 201. The explosion venting device is the explosion venting device 100 disclosed in the above embodiment, so it has all the technical effects of the above explosion venting device 100, which will not be elaborated herein.

[0056] In some embodiments, as Figure 6 shown, a functional module 202 is provided on the top of the cabinet body 201. The functional module 202 includes a heat dissipation module. The heat dissipation module can adopt a fin radiator or a cooling fan to dissipate heat from the equipment in the cabinet body 201 and ensure the stable operation of the energy storage cabinet 200. Of course, the functional module 202 can also include a liquid cooling unit located in the housing. The liquid cooling unit can adopt a split unit, with the external unit arranged in the housing of the functional module 202 and the internal unit arranged in the cabinet body 201 to dissipate heat from the equipment in the cabinet body 201 and ensure the stable operation of the energy storage cabinet 200.

[0057] In some embodiments, as Figure 5 shown, the explosion venting device 100 can be arranged in the functional module 202 and located at the top of the cabinet body 201. Among them, three bursting discs 1021 are arranged on the explosion venting plate 102 of the explosion venting device 100, and each bursting disc 1021 is coaxially arranged to reduce the occupied space of the explosion venting device 100 in the functional module 202 and at the same time reduce the space required when the venting channel 101 is opened. In addition, a pressure relief channel 2021 communicating with the outside of the energy storage cabinet 200 is arranged on the functional module 202 to make the pressure in the functional module 202 less than the pressure in the cabinet body 201 during an explosion. When the preset explosion venting pressure is reached, the bursting disc 1021 opens towards the pressure relief direction to realize the connection between the venting channel 101 and the pressure relief channel 2021, and then realize directional pressure relief to reduce the damage caused by the explosion.

[0058] In some embodiments, a cavity for the bursting disc 1021 to open is formed in the functional module 202. By opening a venting port corresponding to the bursting disc 1021 on the top of the cabinet body 201, the explosion venting device 100 is abutted against the top of the cabinet body 201 through a sealing member 103, so as to seal and install the explosion venting device 100 at the venting port position of the cabinet body 201, and at the same time make the explosion venting device 100 located in the cavity of the functional module 202 to ensure that when an explosion occurs inside the energy storage cabinet 200, the explosion pressure and flame are first vented through the explosion venting device 100 and then through the pressure relief channel 2021 of the functional module 202 to the external environment. In addition, by setting the functional module 202, it is also possible to avoid the problem that the explosion venting device cannot be opened normally due to the influence of snow load when the explosion venting device 100 is installed on the top of the cabinet body 201.

[0059] The embodiment of the present application also discloses an energy storage system, including an energy storage cabinet, which is the energy storage cabinet 200 disclosed in the above embodiment. Therefore, it has all the technical effects of the above energy storage cabinet 200, which will not be elaborated herein again.

In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.
