[0033] Embodiment 1

[0034] See also Figures 1 to 3 As shown, the battery storage device provided in the present application is mainly used for temporary storage of lithium-ion battery products, and can avoid potential safety hazards caused by lithium-ion battery products during long-term storage.

[0035] Specifically, the battery storage device includes a storage rack 101, a detection mechanism 102, and an early warning mechanism. The storage rack 101 can be used to place batteries of the same type or different types, and the detection mechanism 102 is installed on the storage rack 101 to monitor the status of the battery, so as to determine whether the battery is in a normal state or a thermal runaway state. When the detection mechanism 102 detects that the battery is in a thermal runaway state, the detection mechanism 102 is connected to the early warning mechanism in communication to send the detected status information to the early warning mechanism, and the early warning mechanism sends an early warning signal based on the status information to prompt the relevant operators to handle it as soon as possible.

[0036] The battery storage device provided in the present application has a thermal runaway safety warning function, which can promptly issue a warning signal to prompt relevant operators to handle the situation before the lithium-ion battery product has a fire or explosion, thereby achieving early warning and pre-control of fires caused by lithium-ion batteries, reducing the occurrence of safety hazards and economic losses.

[0037] In an optional solution of this embodiment, the storage rack 101 is specifically made of stainless steel. The storage rack 101 includes a frame, at least one layer board 103 and a fireproof partition board 104 located on the layer board 103. Figure 1 As shown, the frame includes a top plate 105 and two side plates 106. Each side plate 106 includes two columns 107 arranged at intervals and a plurality of beams 108 connecting the two columns 107. In order to improve the stability of the storage rack 101, the beams 108 between the two columns 107 include horizontal beams 108 and inclined beams 108. The layer plate 103 is installed in the space enclosed by the top plate 105 and the two side plates 106, and the structure is more stable and has a dustproof function. Figure 1Four layers 103 are shown in the figure, and the four layers 103 are arranged at intervals along the height direction. The arrangement of multiple layers 103 can enable the storage rack 101 to store more batteries. Of course, the number of layers 103 is not limited to the four shown in the figure, and one, two, three or more layers 103 can also be arranged according to actual conditions.

[0038] Optionally, the fireproof partition 104 is used to isolate lithium-ion battery products. When the battery on one side of the fireproof partition 104 catches fire, the fireproof performance of the fireproof partition 104 can prevent the battery on the other side from being affected. Specifically, the fireproof partition 104 is made of stainless steel. Figure 2 As shown, the fireproof partition 104 includes a panel body 109 and a fixing device 110. The fixing device 110 can be configured as a slot type or a cylinder type, and the fixing device 110 is sleeved on the layer board 103 to be reliably connected to the layer board 103. The panel body 109 is connected to the fixing device 110 to separate the supporting space 111 of the layer board 103 into a plurality of battery storage areas 112.

[0039] Preferably, a layer of insulating powder is sprayed on the surface of the board body 109. The insulating powder is specifically insulating resin, so that an insulating layer can be formed on the board body 109, thereby preventing the battery from igniting when in contact with the board body 109, thereby reducing safety hazards.

[0040] In an optional solution of this embodiment, the detection mechanism 102 includes a temperature sensor 113, and the temperature sensor 113 is installed on the board body 109 of the fireproof partition 104. Optionally, a temperature sensor 113 is provided on one side board 106 surface or both side boards 106 surfaces of the board body 109 to detect the temperature around the fireproof partition 104, and send the detected temperature data to the early warning mechanism. According to the temperature data, the early warning mechanism can judge the battery status, and thus send a corresponding early warning signal.

[0041] In an optional solution of this embodiment, the detection mechanism 102 includes a gas detector 114, which is installed in the middle of the upper edge of the supporting space 111 of the layer plate 103. The gas detector 114 is used to detect thermal runaway characteristic gases and smoke. When the battery has thermal runaway, thermal runaway characteristic gases and smoke such as carbon monoxide and / or hydrogen will be generated. The gas detector 114 is located in the upper center of the supporting space 111 of each layer plate 103, and can detect the rising thermal runaway characteristic gases and / or smoke, and send the detected data to the early warning mechanism, and the early warning mechanism can issue a corresponding early warning signal based on the data.

[0042] Specifically, the gas detector 114 may be installed on the bottom surface of the layer plate 103 above the layer plate 103 to be detected. For the topmost layer plate 103 , the gas detector 114 may be installed on the bottom surface of the top plate 105 .

[0043] In an optional solution of this embodiment, the warning mechanism includes a warning controller 115 and an alarm bell 116. The warning controller 115 is in communication connection with the alarm bell 116 so that the alarm bell 116 emits an alarm bell 116 sound. Figure 1 As shown, the early warning controller 115 is installed at the top left edge of the storage rack 101. The early warning controller 115 is connected to the detection mechanism 102 for communication. Its function is to read the detection data of the detection mechanism 102 in real time, and perform data analysis and threshold determination, so as to transmit relevant instructions to the alarm 116. The alarm 116 is installed at the top right edge of the storage rack 101. When receiving the instruction of the early warning controller 115, the alarm 116 can be sounded to remind relevant personnel to check the abnormal phenomenon on site.

[0044] Optionally, the battery storage device further includes a power supply device, which is specifically a 12V or 24V DC power supply, and the power supply device is used to supply power to the gas detector 114 , the early warning controller 115 and the alarm 116 .

[0045] Embodiment 2

[0046] The battery storage device in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0047] See also Figure 1 As shown, in an optional solution of this embodiment, the battery storage device also includes a fire extinguishing mechanism 117. The fire extinguishing mechanism 117 includes a fire extinguishing container 118 and a connecting pipe 119. The fire extinguishing container 118 is loaded with fire extinguishing gas, and the fire extinguishing container 118 is placed under the bottom layer plate 103 to avoid damage to the fire extinguishing container 118 when the battery catches fire. The connecting pipe 119 is connected to the fire extinguishing container 118 so that the fire extinguishing gas fills the connecting pipe 119. The connecting pipe 119 is coiled and installed on the frame and each layer plate 103, and the connecting pipe 119 is formed of a hot-melt material. When the temperature of the storage space exceeds the melting temperature of the connecting pipe 119, the connecting pipe 119 softens and ruptures to release the internal gas, thereby cooling the battery and extinguishing the fire.

[0048] In the optional scheme of this embodiment, the fire extinguishing gas is perfluorohexanone. Perfluorohexanone has high thermal stability, can be quickly gasified and absorb a large amount of heat, thereby reducing the temperature of the surface of the burning object and achieving the purpose of extinguishing the fire. During the fire extinguishing process, perfluorohexanone can reduce the oxygen concentration in the fire scene, form an inert gas layer, isolate the contact between the air and the surface of the burning object, and effectively inhibit the progress of combustion. Perfluorohexanone is a good electrical insulating material that can effectively isolate the contact between the power supply and the fire to prevent electric sparks from causing fires.

[0049] In an optional solution of this embodiment, the battery storage device further includes at least one of an aerosol fire extinguisher 120, a fire blanket 121, and a fire sand box 122. The use of the above fire-fighting facilities to control the spread of thermal runaway will not cause adverse effects on lithium-ion battery products. For example, the use of water spray fire-fighting measures will cause lithium-ion battery products to be soaked in water and scrapped.

[0050] Specific as Figure 3 As shown, the fire blanket 121 can be placed on the side of the storage rack 101 and at a height that is easy to take, so that the operator can easily take it and cover the lithium-ion battery products with potential safety hazards. The aerosol fire extinguisher 120 is placed on the ground on the left side of the storage rack 101, and the fire sand box 122 is placed on the ground on the other side of the storage rack 101. When the lithium-ion battery products have potential safety hazards or have leaked, caught fire or exploded, the operator can transfer the lithium-ion battery products to the fire sand box 122 for fire-fighting treatment or transfer them to a designated location to prevent the fire from spreading while ensuring safety.

[0051] This application combines artificial fire extinguishing methods with forced fire extinguishing methods, and combines fire warning with safe fire fighting, so it has a high safety factor and can be applied industrially.

[0052] Embodiment 3

[0053] Embodiment 3 of the present application provides a battery storage device, including the battery storage device of any of the above embodiments, and thus has all the beneficial technical effects of the battery storage device of any of the above embodiments, which will not be elaborated here.

[0054] Embodiment 4

[0055] Embodiment 4 of the present application provides a fire early warning and pre-control method, the specific method is as follows:

[0056] When the gas detector 114 transmits data information such as the characteristic gas of thermal runaway (carbon monoxide or / or hydrogen) and smoke generated by thermal runaway to the early warning controller 115, the early warning controller 115 determines that the concentration of the characteristic gas of thermal runaway is between 0.1%LEL and 5%LEL (LEL is the lower explosion limit of combustible gas), and sends the early warning instruction to the alarm 116, and the alarm 116 sounds an alarm. After hearing the alarm 116, the relevant operator determines whether the lithium-ion battery product has a fire or explosion accident. If not, the lithium-ion battery product is transferred to the fire sand box 122, covered with a fire blanket 121, and transferred to a designated location under the condition that safety measures are in place; if a fire occurs but there is no explosion, the lithium-ion battery product on fire is covered with a fire blanket 121 under the condition that safety measures are in place, and the handheld aerosol fire extinguisher 120 is used to extinguish the fire; if an explosion occurs, the lithium-ion battery product on fire is covered with a fire blanket 121, and the scene is quickly left.

[0057] When the temperature sensor 113 transmits the temperature data to the early warning controller 115, the early warning controller 115 determines that the temperature reaches 70°C or above, and sends the early warning instruction to the alarm 116, and the alarm 116 sounds an alarm. After hearing the alarm 116, the relevant operator determines whether the lithium-ion battery product has a fire or explosion accident. If not, the lithium-ion battery product is transferred to the fire sand box 122 and covered with a fire blanket 121, and transferred to a designated location under the condition that safety measures are in place; if a fire occurs but there is no explosion, the lithium-ion battery product on fire is covered with a fire blanket 121 under the condition that safety measures are in place, and the handheld aerosol fire extinguisher 120 is used to extinguish the fire; if an explosion occurs, the lithium-ion battery product on fire is covered with a fire blanket 121, and the scene is quickly left.

[0058] Furthermore, operators need to implement safety measures when extinguishing fires. Safety measures mainly refer to wearing goggles, gas masks, insulating gloves, heat-insulating gloves, etc., and staying at least two meters away from the accident site.

[0059] When a lithium-ion battery product catches fire or explodes, if the temperature exceeds 400°C or above, the connecting pipe 119 will soften. At this time, the perfluorohexanone gas in the fire extinguishing container 118 will cover the lithium-ion battery product that has caught fire or exploded to cool it down and extinguish the fire.

[0060] Furthermore, when the lithium-ion battery product catches fire and explodes and is extinguished, the lithium-ion battery product is transferred to the fire sand box 122 and covered with a fire blanket 121, and then transferred to a designated location, with safety measures in place.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
