Therefore, before the battery 15 occurs thermal runaway, a large amount of side reactions will occur in the battery 15 to generate gas.

[0047] According to some embodiments, the liquid fire-fighting medium introduced into the channel flows at a preset flow rate. The liquid fire-fighting medium flowing at a preset flow rate can cool the battery cabinet 10, for example, and can also reduce the battery fire-fighting time.

[0048] Optionally, the battery cabinet 10 further comprises a laser sensing device, wherein the laser sensing device is arranged on the drainage pipe 13.

[0052] According to some embodiments, Figure 3 A structural schematic diagram of a battery plug-in box is shown. As Figure 3 As shown, the battery plug-in box can be a storage energy lithium battery plug-in box. Optionally, the liquid fire-fighting medium can also be referred to as a liquid medium. The fire-fighting device further comprises a fire alarm controller and an audible and visual alarm, wherein the fire alarm controller is connected with the composite detector, and the audible and visual alarm is connected with the fire alarm controller. The audible and visual alarm is used to issue alarm information.

[0053] In some embodiments, the fire-fighting device further comprises a display panel. The display panel is connected with the fire alarm controller. The display panel is used to confirm whether the battery fire-fighting is completed. The display panel can also be referred to as a display, a display screen, etc. The present disclosure is not limited in this regard.

[0054] According to some embodiments, the fire-fighting device may, for example, further comprise a battery management system (BMS). The BMS may, for example, be connected with the composite detector, receive information transmitted by the composite detector, and transmit the information to the cloud, so as to confirm whether the battery fire-fighting is completed from the information in the cloud.

[0055] As shown in Figure 4 Figure 4 is a flowchart of a battery fire-fighting method according to an embodiment of the present disclosure. The method may, for example, be implemented by a computer program and run on a device for battery fire-fighting. The computer program may, for example, be integrated in an application or run as a tool-type application. For example, the battery fire-fighting method may, for example, be executed by a battery fire-fighting device, and may, for example, also be executed by a fire-fighting equipment.

[0056] The battery fire-fighting method may, for example, comprise the following steps.

[0057] S101, obtaining, by a gas pressure sensing device, a gas pressure value of a battery corresponding to the gas pressure sensing device in a battery insertion box;

[0058] According to some embodiments, the gas pressure sensing device may, for example, be a device for collecting gas pressure. The gas pressure sensing device is not limited to a specific device. The gas pressure sensing device may, for example, be a gas pressure sensor. For example, when the device identifier corresponding to the gas pressure sensing device changes, the gas pressure sensing device may also change accordingly.

[0059] In some embodiments, at least one battery may, for example, be arranged in the battery insertion box. For example, one battery may, for example, be arranged in the battery insertion box. The gas pressure sensing device may, for example, correspond to one battery one-to-one, for example, one gas pressure sensing device may, for example, collect the gas pressure value of one battery. That is, one gas pressure sensing device may, for example, be arranged on the drainage pipe corresponding to one battery.

[0060] According to some embodiments, the battery insertion box may, for example, be a lithium battery insertion box. The battery may, for example, be a lithium battery. The present disclosure is not limited thereto.

[0061] It is easy to understand that the gas pressure value is used to indicate the pressure value of the battery gas. The gas pressure value is not limited to a specific value. For example, when the collection time point of the gas pressure value changes, the gas pressure value may also change accordingly. For example, when the pressure of the battery gas changes, the gas pressure value may also change accordingly.

[0062] Optionally, the fire-fighting equipment may, for example, obtain, by a gas pressure sensing device, a gas pressure value of a battery corresponding to the gas pressure sensing device in a battery insertion box.

[0063] ​S102, in the case that the air pressure value is greater than the air pressure threshold value, the induction valve on the drainage pipe is opened, and a pressure boosting signal is sent to the pressure boosting pump;

[0064] According to some embodiments, the air pressure threshold value may, for example, be used to indicate a threshold value for determining whether to open the induction valve. The air pressure threshold value is not particularly a fixed threshold value. For example, the air pressure threshold value can be modified when the fire-fighting device receives a modification instruction for the air pressure threshold value. For example, different batteries can correspond to different air pressure threshold values.

[0065] In some embodiments, the drainage pipe refers to a channel for pouring liquid fire-fighting medium from the channel of the upper cover of the plug-in box to the battery.

[0066] It is easy to understand that the pressure boosting pump refers to a device that can adjust the medium information of the liquid fire-fighting medium in the channel of the upper cover of the plug-in box. The medium information adjustment includes but is not limited to medium flow rate adjustment, medium pressure adjustment, etc.

[0067] According to some embodiments, in the case that the fire-fighting device obtains the air pressure value, the air pressure value can be judged. In the case that the air pressure value is greater than the air pressure threshold value, the induction valve on the drainage pipe is opened, and a pressure boosting signal is sent to the pressure boosting pump, so that the pressure boosting pump adjusts the medium information of the liquid fire-fighting medium in the channel of the upper cover of the plug-in box.

[0068] S103, the liquid fire-fighting medium is poured into the battery corresponding to the air pressure sensing device through the nozzle of the drainage pipe, so as to pour fire-fighting to the battery corresponding to the air pressure sensing device.

[0069] In some embodiments, the liquid fire-fighting medium may, for example, be a combination of a coolable gas medium and an oil. For example, when the composition of the gas medium or the oil in the liquid fire-fighting medium changes, the liquid fire-fighting medium can also change accordingly. For example, different liquid fire-fighting media can be set for different battery identifiers.

[0070] According to some embodiments, the fire-fighting device can pour the liquid fire-fighting medium in the channel of the upper cover of the plug-in box into the battery corresponding to the air pressure sensing device through the nozzle of the drainage pipe, so as to pour fire-fighting to the battery corresponding to the air pressure sensing device.

[0071] Optionally, when the battery is normally running, the pressure boosting pump can run at a first power, so that the liquid fire-fighting medium can flow slowly in the channel. When the laser sensing device detects that the distance change of the explosion-proof valve of the battery is greater than a preset distance, the fire-fighting device can control the valve of the induction valve to open, and send a pressure boosting signal to the pressure boosting pump. The pressure boosting pump may, for example, run at a second power to increase the flow rate and pressure of the liquid fire-fighting medium. The second power is greater than the first power.

[0072] In one embodiment of the present disclosure, the gas pressure value corresponding to the battery corresponding to the gas pressure sensing device in the battery plug-in box is obtained by the gas pressure sensing device; in the case where the gas pressure value is greater than the gas pressure threshold value, the sensing valve on the drainage pipe is controlled to open, and a pressure boosting signal is sent to the pressure boosting pump; and the liquid fire-fighting medium is injected into the battery corresponding to the gas pressure sensing device through the nozzle of the drainage pipe to perform injection fire-fighting on the battery corresponding to the gas pressure sensing device. Therefore, before the battery occurs thermal runaway, a large amount of side reactions will occur in the battery, generating gas. When the gas pressure sensing device determines that the gas pressure in the battery is greater than the gas pressure threshold value, the liquid fire-fighting medium can be directly injected into the battery through the nozzle of the drainage pipe and the battery explosion-proof valve, the battery can be injected and fire-fought, the energy storage box does not need to be filled with liquid fire-fighting medium and then immersed in the battery core, the amount of liquid fire-fighting medium required is reduced, the injection path length of the liquid fire-fighting medium is reduced, the battery fire-fighting time is reduced, and the probability of completing battery fire-fighting before the battery thermal runaway is increased. In addition, when a certain battery is fire-fought for thermal runaway, the adjacent battery can not be affected, and the fire-fighting loss can be reduced.

[0073] As shown in Figure 5 Figure 5 is a flowchart of a battery fire-fighting method according to one embodiment of the present disclosure. The battery fire-fighting method of the present disclosure may, for example, include:

[0074] S201, obtaining, by a gas pressure sensing device, a gas pressure value corresponding to a battery corresponding to the gas pressure sensing device in a battery plug-in box;

[0075] The specific process is described above, and will not be repeated here.

[0076] S202, in the case where the gas pressure value is greater than the gas pressure threshold value, controlling the sensing valve on the drainage pipe to open, and sending a pressure boosting signal to the pressure boosting pump;

[0077] The specific process is described above, and will not be repeated here.

[0078] S203, injecting a liquid fire-fighting medium into the battery corresponding to the gas pressure sensing device through the nozzle of the drainage pipe to perform injection fire-fighting on the battery corresponding to the gas pressure sensing device;

[0079] The specific process is described above, and will not be repeated here.

[0080] S204, obtaining, by a laser sensing device, laser information corresponding to the battery plug-in box;

[0081] In some embodiments, when the fire-fighting device controls the sensing valve on the drainage pipe to open, the laser information corresponding to the battery plug-in box can be obtained by the laser sensing device. The laser information may, for example, be generated when a chemical reaction occurs in the battery.

[0082] ​According to some embodiments, the laser information is not fixed. For example, when the laser intensity corresponding to the laser information changes, the laser information can also change accordingly. For example, when the laser duration corresponding to the laser information changes, the laser information can also change accordingly.

[0083] S205, transmitting the laser information to the fire alarm controller through the composite detector, so that the fire alarm controller controls the sound and light alarm to issue alarm information according to the laser information, or transmits the laser information to the display device.

[0084] According to some embodiments, the fire alarm controller refers to a control device for receiving a fire signal and starting the sound and light alarm to alarm.

[0085] In some embodiments, when the fire-fighting equipment can transmit the laser information collected by the laser sensing device to the fire alarm controller through the composite detector. The fire alarm controller controls the sound and light alarm to issue alarm information according to the laser information, or the fire alarm controller can transmit the laser information to the display device.

[0086] For example, the alarm information can be sound alarm information. Different laser information can correspond to different sound frequencies.

[0087] According to some embodiments, when the display device obtains the laser information, the display device can display the laser information.

[0088] In some embodiments, the composite detector can collect multiple information. When the composite detector obtains multiple information, the composite detector can transmit the multiple information to the battery management system (BMS). The BMS can be connected to the composite detector, for receiving the information transmitted by the composite detector, and transmitting the information to the cloud, so as to confirm whether the battery fire protection is completed according to the information in the cloud.

[0089] In one embodiment of the present disclosure, the laser information corresponding to the battery plug-in box is obtained by the laser sensing device; the laser information is transmitted to the fire alarm controller through the composite detector, so that the fire alarm controller controls the sound and light alarm to issue alarm information according to the laser information, or transmits the laser information to the display device. Therefore, the time length of the battery thermal runaway fire protection can be reduced, and the fire protection efficiency can be improved. In addition, the acquisition time length of the battery explosion-proof valve explosion can be reduced, and the fire protection efficiency can be improved.

[0090] The following is an embodiment of the device of the present disclosure, which can be used to execute the method embodiment of the present disclosure. For details not disclosed in the device embodiment of the present disclosure, please refer to the method embodiment of the present disclosure.

[0091] Please refer to Figure 6 which shows a structural schematic diagram of a battery fire-fighting device provided by an example embodiment of the present disclosure. The battery fire-fighting device can be realized by software, hardware or a combination of the two to become all or part of the device. The battery fire-fighting device 600 includes a gas pressure value acquisition unit 601, a signal sending unit 602 and a medium perfusion unit 603, wherein:

[0092] The gas pressure value acquisition unit 601 is configured to acquire the gas pressure value corresponding to the battery plug-in box through the gas pressure sensing device;

[0093] The signal sending unit 602 is configured to control the sensing valve on the drainage pipe to open and send a pressure boosting signal to the pressure boosting pump to adjust the liquid fire-fighting medium in the liquid fire-fighting medium passage of the plug-in box cover when the gas pressure value is greater than the gas pressure threshold value;

[0094] The medium perfusion unit 603 is configured to perfuse the liquid fire-fighting medium to the battery in the battery plug-in box through the nozzle of the drainage pipe to perfuse the fire-fighting for the battery.

[0095] According to some embodiments, the signal sending unit 602 is further configured to:

[0096] acquire the laser information corresponding to the battery plug-in box through the laser sensing device;

[0097] transmit the laser information to the fire alarm controller through the composite detector to make the fire alarm controller control the audible and visual alarm to issue the alarm information or control the display device to display the laser information.

[0098] It should be noted that the battery fire-fighting device provided by the above embodiment is only used as an example to illustrate the division of the above functional modules when the battery fire-fighting method is executed. In actual application, the above functions can be completed by different functional modules according to needs, that is, the internal structure of the device is divided into different functional modules to complete all or part of the functions described above.

Here, it is not repeated.

[0099] The above sequence number of the embodiment of the present disclosure is only for description, not representing the pros and cons of the embodiment.

[0100] In one or more embodiments of this disclosure, a pressure value acquisition unit acquires the pressure value corresponding to the battery compartment via a pressure sensing device; when the pressure value is greater than a pressure threshold, a signal sending unit controls the opening of the sensing valve on the drainage pipe and sends a pressure boosting signal to the booster pump, so that the booster pump adjusts the liquid fire-fighting medium in the liquid fire-fighting medium channel on the top cover of the compartment; a medium filling unit fills the battery in the battery compartment with the liquid fire-fighting medium through the nozzle of the drainage pipe to fill the battery with fire-fighting medium. Therefore, before the battery experiences thermal runaway, a large number of side reactions will occur inside the battery, generating gas. When the pressure sensing device determines that the internal pressure of the battery is greater than the pressure threshold, it can control the liquid fire-fighting medium to be directly filled into the battery through the nozzle of the drainage pipe and the battery explosion-proof valve port, thus filling the battery with fire-fighting medium. This eliminates the need to fill the energy storage tank first and then immerse it into the battery cells, reducing the amount of liquid fire-fighting medium required, reducing the injection path length of the liquid fire-fighting medium, reducing the battery fire-fighting time, and increasing the probability of completing battery fire-fighting before thermal runaway.
