[0002] In order to deal with possible thermal runaway events of energy storage devices, especially lithium-ion battery packs, a variety of fire protection system designs have been introduced in the market to improve safety. However, these existing technologies still face significant challenges in practical applications. Although most existing fire protection systems are equipped with basic thermal management and fire extinguishing mechanisms, such as temperature monitoring, overheating warnings, and automatic fire extinguishing devices, they are unable to handle the rapid smoke emissions caused by thermal runaway. Most of these systems rely on passive smoke exhaust strategies of natural ventilation rather than active and efficient smoke management technologies.

However, the existing passive smoke exhaust mechanism lacks immediate response capability and often cannot quickly and effectively exhaust the smoke, leading to the following key problems: First, the smoke accumulated in the cabinet may not only trigger the heat transfer effect of adjacent battery packs, aggravating the overall overheating risk, but also damage surrounding electrical components and affect the stable operation of the entire system; second, the slow gas flow in the smoke exhaust duct limits the rapid evacuation of heat, delays the effective cooling of the thermal runaway battery pack, and increases the risk of fire spread and explosion.

[0036] like Figure 3 , Figure 4 As shown, the embodiment of the utility model further provides an energy storage container, which includes a container 600, the container 600 includes a frame 610, and a plurality of groups of symmetrically arranged battery packs 700 built into the frame 610, and the backs of the plurality of groups of battery packs 700 are arranged opposite to each other; a smoke exhaust assembly 100, the smoke exhaust assembly 100 includes a plurality of pressure relief valves 110 corresponding to and connected to the battery packs 700 one by one, and a smoke exhaust duct 120 provided on one side of the container 600 and connected to the outside, and a smoke exhaust fan 130 provided at the outlet of the smoke exhaust duct 120 and communicating with the pressure relief valve 110; an air inlet assembly 200, the air inlet assembly 200 provided on the other side of the container 600 , which includes an air inlet duct 210 connected to the outside; a branch duct 300, which is arranged in the direction of the pressure relief valve 110, one end of which is connected and connected to the smoke exhaust duct 120, and the other end is connected and connected to the air inlet duct 210, and the side wall of the branch duct 300 is connected and connected to each pressure relief valve 110.

[0037] like Figures 1 to 5As shown, in the present embodiment, the smoke exhaust device is detachably mounted on a container 600, and the container 600 is rectangular, comprising a frame 610, and a plurality of groups of battery packs 700 symmetrically arranged in the frame 610. Preferably, in the present embodiment, five groups of battery packs 700 are provided, each group of battery packs 700 is symmetrically arranged in two rows, and each row of battery packs 700 includes eight battery packs 700, which are stacked in sequence longitudinally; the electrical energy storage capacity of the container 600 is effectively guaranteed.

[0038] In this embodiment, the smoke exhaust device includes a smoke exhaust component 100, a branch pipe 300 and an air intake component 200 which are sequentially arranged and connected along the length direction of the container 600. The purpose is to build an efficient and reliable smoke exhaust system through a highly integrated design and the coordinated work of each component to ensure the safe operation of the energy storage system.

[0039] In this embodiment, the smoke exhaust assembly 100 includes a plurality of pressure relief valves 110 disposed on the back of the battery pack 700 and corresponding to the battery pack 700, a smoke exhaust pipe 120 disposed on one side of the frame 610 of the container 600 and connected to the outside, and a smoke exhaust fan 130 disposed at the outlet of the smoke exhaust pipe 120 and communicating with the pressure relief valve 110. Among them, the pressure relief valve 110 is precisely designed to respond immediately at the initial stage of abnormal temperature rise of the battery pack 700, automatically open to release internal pressure and smoke, and realize one-by-one monitoring of the status of the battery pack 700. The smoke exhaust pipe 120 is made of high temperature resistant and flame retardant materials to ensure stable operation under extreme conditions. By configuring a high-power smoke extraction fan 130 at the terminal of the smoke exhaust duct 120, since the smoke extraction fan 130 has the characteristics of high rotation speed and large air volume, it can form a strong negative pressure area in a short time, quickly suck the smoke released by the pressure relief valve 110, and discharge it to a safe area through the smoke exhaust duct 120, and by establishing a communication connection between the smoke extraction fan 130 and the pressure relief valve 110, once the pressure relief valve 110 is actuated, the smoke extraction fan 130 can be immediately started to form a strong suction effect, quickly guide out the smoke, and realize active and rapid smoke discharge.

[0040] In this embodiment, the smoke exhaust duct 120 is L-shaped and has a hollow structure. One end of the smoke exhaust duct is detachably mounted on the container 600, and the other end extends along the width direction of the container 600, bends toward the symmetry line direction of the two symmetrically arranged rows of battery packs 700, and is connected to the second manifold 340, so as to simplify the overall structure of the smoke exhaust device and improve the compactness of the structure.

[0041] In this embodiment, the smoke exhaust duct 120 includes a third opening 121 and a fourth opening 122 which are interconnected. The third opening 121 is connected to the outside, and the fourth opening 122 is connected to the second manifold 340. The smoke exhaust fan 130 is arranged at the fourth opening 122, so that the smoke generated by the battery pack 700 can smoothly enter the smoke exhaust duct 120, thereby effectively ensuring the smoothness of smoke emission and reducing the risk of fire and explosion.

[0042] In order to further improve the smoke exhaust efficiency, in this embodiment, an air intake assembly 200 is also included on the other side of the container 600. The air intake assembly 200 includes an air intake duct 210 connected to the outside. The air intake duct 210 is a hollow structure, arranged opposite to the smoke exhaust duct 120, and connected through a branch duct 300. When the smoke exhaust fan 130 is started, the external air is sucked into the air intake duct 210 and the branch duct 300 under the action of the smoke exhaust fan 130. On the one hand, the smoke in the branch duct 300 can be squeezed so that it can be quickly discharged; on the other hand, the external air is allowed to participate in the smoke circulation, promote heat exchange, thereby accelerating the cooling process of the thermal runaway battery pack 700, and effectively improving safety.

[0043] In this embodiment, one end of the air inlet duct 210 is detachably arranged on the container 600 at a position opposite to the first manifold 330, and the other end is connected to the second manifold 340. The air inlet duct 210 includes a first opening 211 and a second opening 212 that are connected to each other. The first opening 211 is connected to the outside, and the second opening 212 is connected to the first manifold 330, and the first opening 211 is larger than the second opening 212. This helps to increase the air intake volume, improve the air intake efficiency, and ensure that sufficient fresh air enters.

[0044] In this embodiment, a filter screen 500 is provided at the first opening 211. The filter screen 500 is rectangular and has a plurality of air holes connected to the air inlet duct 210, and the air holes are arranged in a matrix. The design of the filter screen 500 ensures the cleanliness of the incoming air, reduces the pollution of dust and other impurities to the system, prolongs the service life of the equipment, and maintains good ventilation performance, ensuring the continuous and efficient operation of the system.

[0045] It is worth noting that the air inlet duct 210 can cooperate with the partition of the frame 610 to form an air inlet channel, or can independently form an air inlet channel. Preferably, in this embodiment, the air inlet duct 210 cooperates with the partition of the frame 610 to form an air inlet channel.

[0046] In order to realize synchronous monitoring and smoke exhaust of multiple battery packs 700, in this embodiment, the smoke exhaust device further includes a branch pipe 300, which is arranged between several groups of battery packs 700, one end of which is connected and communicated with the smoke exhaust pipe 120, and the other end is connected and communicated with the air intake pipe 210, and the side wall of the branch pipe 300 is connected and communicated with each pressure relief valve 110. On the one hand, the parallel connection with multiple pressure relief valves 110 is realized to ensure that each battery pack 700 can be in a monitoring state, and each battery pack 700 can perform timely and effective smoke exhaust; on the other hand, the smoke exhaust pipe 120 and the air intake pipe 210 are connected to realize the effective interaction and exhaust of smoke and fresh air.

[0047] In this embodiment, the branch pipe 300 is a hollow structure, and is provided with a plurality of air holes 310 connected to the pressure relief valve 110. A seal 400 is provided between the air hole 310 and the pressure relief valve 110. One side of the seal 400 is in contact with the outer wall of the air hole 310, and the other side is in contact with the outer wall of the pressure relief valve 110. This ensures the effective discharge of smoke and maintains good sealing in non-emergency conditions, preventing external environmental factors from interfering with the normal operation of the battery pack 700. At the same time, it optimizes the flexibility and sealing of emergency response, and enhances the overall reliability and environmental adaptability of the system.

[0048] Preferably, in this embodiment, the number of the air holes 310 matches the number of the pressure relief valves 110 .

[0049] Preferably, in this embodiment, the sealing member 400 is a silicone sealing cotton.

[0050] In this embodiment, the branch pipe 300 includes a plurality of branch pipes 320 connected to the pressure relief valves 110, and a first manifold 330 and a second manifold 340 respectively disposed at both ends of the branch pipe 320. The plurality of air holes 310 are disposed on the branch pipe 320 and arranged along the length direction of the branch pipe 320. One end of the first manifold 330 is connected and communicated with the plurality of branch pipes 320, and the other end is connected and communicated with the air inlet pipe 210. One end of the second manifold 340 is connected and communicated with the plurality of branch pipes 320, and the other end is connected and communicated with the smoke exhaust pipe 120. Through the design of the branch pipe 320 and the first and second manifolds 340, effective centralized and decentralized processing of smoke is achieved, smoke exhaust efficiency is improved, smoke around each battery pack 700 is ensured to be quickly and evenly extracted, the possibility of overheating in a local area is reduced, and the emergency response capability in the case of thermal runaway is further optimized.

[0051] Preferably, in this embodiment, the number of the branch pipes 320 is adapted to the number of individual battery packs 700 in each column of battery packs 700 .

[0052] In this embodiment, the first confluence pipe 330 and the second confluence pipe 340 are arranged vertically, and a plurality of branch pipes 320 are arranged along the length direction of the first confluence pipe 330 and the second confluence pipe 340. The end of the first confluence pipe 330 away from the ground is connected to the air inlet duct 210, and the end of the second confluence pipe 340 away from the ground is connected to the smoke exhaust duct 120. This design not only saves space, but also facilitates the vertical flow of smoke and air, further improving the smoke exhaust efficiency.

[0053] In this embodiment, the smoke exhaust device further includes a control system, which is electrically connected to the pressure relief valve 110 and the smoke exhaust fan 130, respectively. When the control system detects the opening signal of the pressure relief valve 110, it sends a start signal to the smoke exhaust fan 130 to achieve communication connection between the pressure relief valve 110 and the smoke exhaust fan 130. The control system can monitor the opening state of the pressure relief valve 110 in real time, and once the opening signal is received, the smoke exhaust fan 130 is immediately started, realizing instant linkage between the two, greatly improving the emergency response speed and smoke exhaust efficiency.

[0054] In general, when a battery pack 700 experiences thermal runaway, the smoke exhaust device can respond immediately. The rapid opening of the pressure relief valve 110 and the strong suction of the smoke exhaust fan 130 can quickly guide the high-temperature smoke to the outside, effectively avoiding the accumulation of smoke in the container 600, and significantly reducing the risk of damage to adjacent battery packs 700 or electrical equipment due to overheating. Compared with the traditional passive smoke exhaust method, the smoke exhaust speed of this embodiment has been significantly improved, the smoke exhaust time has been greatly shortened, the spread of thermal runaway has been effectively controlled, and the safety factor and overall stability of the energy storage system have been effectively improved.
