[0002] With the rapid development of new energy batteries, the application scope of energy storage batteries is also becoming wider and wider. In industrial and commercial applications, multiple battery packs are usually stacked to increase the total battery capacity. In the use of energy storage batteries, the research on their safety performance is particularly important, among which the fire protection performance of energy storage is of paramount importance.

[0003] In existing energy storage fire protection structures, fire protection devices are usually installed separately in each battery pack, which occupies space inside the battery pack. At the same time, the separate installation of fire protection devices in each battery pack increases the manufacturing cost.

[0004] Existing energy storage fire protection structures have low space utilization rates, resulting in low energy density of battery packs. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the overall structure provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the thermal runaway protection device provided in this embodiment of the utility model; Figure 3 This is a side view of the support frame, fire detection integrated module, and battery pack provided in this embodiment of the utility model. Figure 4 This is a front view schematic diagram of the support frame provided in an embodiment of this utility model; Figure 5 This is a schematic diagram of signal transmission provided by an embodiment of this utility model. (See diagram below.) Figures 1 to 5The energy storage fire protection structure shown includes: a thermal runaway protection device 1, a battery pack 2, an inhibitor liquid pipeline 3, and a detection pipeline 4. Multiple battery packs 2 are stacked. The thermal runaway protection device 1 is located on top of the multiple battery packs 2. The battery pack 2 has an inhibitor liquid interface 21 and a detection interface 22. The thermal runaway protection device 1 includes a main control board 11, a fire protection detection integrated module 12, and an aerosol 13. The fire protection detection integrated module 12 and the aerosol 13 are respectively connected to the main control board 11 via signal connections. One end of the inhibitor liquid pipeline 3 is connected to the inhibitor liquid interface 21, and the other end is connected to the aerosol 13. One end of the detection pipeline 4 is connected to the detection interface 22, and the other end is connected to the fire protection detection integrated module 12.

[0027] For example, in this embodiment of the present invention, five battery packs 2 are provided, such as... Figure 1 The diagram only shows the connection between the thermal runaway protection device 1 and one of the battery packs 2. In reality, the fire detection integrated module 12 is connected to each battery pack 2 via the detection pipeline 4, and the aerosol 13 is connected to each battery pack 2 via the suppressant liquid pipeline 3. The detection interface 22 on each battery pack can be set with a switch function, allowing the fire detection integrated module 12 to cyclically extract and detect the gas in each battery pack 2. When the detection result exceeds the standard, an abnormal signal is sent to the main control board 11. The main control board 11 then sends a control signal to the aerosol 13, causing the extinguishing agent to be injected from the suppressant liquid pipeline 3 into the abnormal battery pack 2, completing the fire protection process. Compared to traditional technologies that require fire protection devices in each battery pack 2, this fire protection structure only requires one thermal runaway protection device 1 to monitor multiple battery packs 2, thereby reducing the space occupied within the battery packs 2 and increasing the energy density of the battery packs 2.

[0028] This utility model provides an energy storage fire protection structure. By setting up a thermal runaway protection device and connecting it to multiple battery packs 2 through an inhibitor liquid pipeline 3 and a detection pipeline 4, a fire protection structure is formed where one thermal runaway protection device 1 corresponds to multiple battery packs 2. The gas in each battery pack 2 is cyclically extracted through the detection pipeline 4, and the extracted gas is detected sequentially by the fire detection integrated module 12. When the extracted gas exceeds the standard, the fire detection integrated module 12 sends a signal to the main control board 11, which controls the aerosol 13 to start, delivering the extinguishing agent to the corresponding battery pack 2 through the inhibitor liquid pipeline 3, thereby forming a fire protection structure. By adopting a fire protection structure where one thermal runaway protection device 1 corresponds to multiple battery packs 2, it is not necessary to set up a separate fire protection structure in each battery pack 2, which can effectively solve the problem of low energy density of battery packs due to low space utilization in the prior art.

[0029] Optionally, the fire detection integrated module 12 includes an air pump 121 and a detector 122. The air pump 121 is used to extract gas from the battery pack 2 into the fire detection integrated module 12. The detector 122 is connected to the main control board 11 and is used to detect the extracted gas. The detector 122 includes a temperature detector 1221, a smoke detector 1222, and an electrolyte gas content detector 1223.

[0030] For example, in this embodiment of the present invention, when gas is extracted from the battery pack 2, the temperature detector 1221 can detect the temperature of the extracted gas, the smoke detector 1222 can detect the particle content of the extracted gas, and the electrolyte gas content detector 1223 can detect the carbon monoxide and hydrogen content in the extracted gas. When two of the detected values ​​exceed the normal values, it is determined that the battery pack 2 has malfunctioned and fire-fighting operations are required. At this time, the detector 122 sends an abnormality signal to the main control board 11 to carry out subsequent fire-fighting work. By setting this structure, the extracted gas can be judged more accurately, thereby improving the detection accuracy of this fire-fighting structure.

[0031] Optionally, the thermal runaway protection device 1 also includes a power supply interface 14 and an indicator light 15, which are electrically connected to the main control board 11.

[0032] For example, in this embodiment of the present invention, the main control board 11 is powered by the power supply interface 14, and the main control board 11 then powers the fire detection integrated module 12 and the aerosol 13. When the circuit connection is smooth, the indicator light 15 is powered on and illuminated, thus proving that the structure is operating normally. By setting this structure, the ease of operation of the fire protection structure is improved.

[0033] Optionally, the thermal runaway protection device 1 also includes a buzzer 16, which is connected to the main control board 11 via signal.

[0034] For example, in this embodiment of the present invention, when the fire detection integrated module 12 detects an abnormal gas in the battery pack 2, it sends an abnormal signal to the main control board 11. At this time, the main control board 11 sends a signal to the buzzer 16 to start, so that the staff can know that an abnormality has occurred in the battery pack 2 and take timely subsequent fire response measures. By setting the buzzer 16, the practicality of this fire protection structure is improved.

[0035] Optionally, two aerosols 13 are provided, with the two aerosols 13 arranged at intervals.

[0036] For example, in this embodiment of the present invention, two bottles of aerosol 13 are installed, which can be compatible with the fire extinguishing capacity of each battery pack 2, and can also serve as two fire extinguishing functions, thereby improving the stability of the fire protection structure.

[0037] Optionally, the main control board 11 is provided with a communication transmission device 17, and the main control board 11 is connected to an external host computer via the communication transmission device 17.

[0038] For example, in this embodiment of the present invention, by setting up a communication transmission device 17, when the main control board 11 receives an abnormal signal from the fire detection integration module 12, it can transmit the signal to an external host computer through the communication transmission device 17. Through human-machine interaction with EMS or BMS, the data inside the battery pack 2 can be transmitted in real time, and can be viewed and operated remotely. When an abnormality is detected inside the battery pack 2, it will communicate with EMS or BMS to quickly determine which battery pack it is, and then link the fire-fighting equipment to carry out subsequent fire-fighting work.

[0039] Optionally, it also includes a support frame 5, which includes a vertical support plate 51 and multiple horizontal support plates 52. The multiple horizontal support plates 52 are arranged in parallel and spaced apart on the vertical support plate 51, and the thermal runaway protection device 1 and multiple battery packs 2 are respectively installed on the multiple horizontal support plates 52.

[0040] For example, in this embodiment of the present invention, by setting a support frame 5, multiple battery packs 2 and thermal runaway protection devices 1 can be separated. When one of the battery packs 2 malfunctions and fire protection is activated, it prevents it from affecting adjacent battery packs 2 or thermal runaway protection devices 1. Furthermore, by setting a support frame 5, the structure becomes a whole, making it easier to move the whole structure when needed, thereby further improving the ease of operation of the fire protection structure.

[0041] Optionally, the support vertical plate 51 is provided with an inhibition liquid pipeline mounting groove 511 and a detection pipeline mounting groove 512 along the vertical direction. The inhibition liquid pipeline 3 is set in the inhibition liquid pipeline mounting groove 511, and the detection pipeline 4 is set in the detection pipeline mounting groove 512.

[0042] For example, in this embodiment of the present invention, since the thermal runaway protection device 1 needs to be connected to multiple battery packs 2 through the inhibitory liquid pipeline 3 and the detection pipeline 4, there are many pipelines, and the pipelines may become entangled, making them inconvenient to manage. By setting the inhibitory liquid pipeline installation groove 511 and the detection pipeline installation groove 512, the inhibitory liquid pipeline 3 can be set in the inhibitory liquid pipeline installation groove 511 and the detection pipeline 4 can be set in the detection pipeline installation groove 512, thereby preventing the different pipelines from becoming entangled, thus further improving the ease of operation of this fire protection structure.
