DETAILED DESCRIPTION

[0068] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0069] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0070] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0071] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0072] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0073] This embodiment introduces a fire treatment method, which is applied to an energy storage device, wherein the energy storage device includes an energy storage cabinet, and at least one battery pack is arranged in the energy storage cabinet. The energy storage device can be an energy storage device, an energy storage cabinet, an energy storage container and other equipment. The energy storage device can be a container-type energy storage product, an industrial and commercial energy storage product, or a home storage product. No specific limitation is made here. At least one battery pack is arranged in the cabinet of the energy storage device, and the battery pack serves as a power storage unit of the energy storage device. Only one battery pack or multiple battery packs can be arranged in the cabinet of the energy storage device. The number of battery packs in the cabinet of the energy storage device can be determined according to the function of the energy storage device. For example, the energy storage device is used as a backup power supply for some industrial equipment and requires a larger capacity. In this case, multiple battery packs can be arranged in the cabinet of the energy storage device. For another example, the energy storage device is used for personal home use and does not require a larger capacity, so only one battery pack can be arranged.

[0074] First, specific scenarios in which the energy storage device provided in this application may be deployed are introduced.

[0075] In the embodiments of the present application, the energy storage device can be applied to the user side. For example, by installing an energy storage device in a hospital, using photovoltaic and energy storage devices, 100% clean energy can be used in the hospital area, thereby improving the image of the hospital. For another example, a large electricity user can save electricity bills by installing an energy storage device at home.

[0076] It can also be applied to the power generation side. For example, when large-scale new energy is connected to the grid, the use of electrochemical energy storage devices can support the stable operation of the power grid.

[0077] It can also be applied to the power grid side. For example, when a power outage occurs in the power grid, the energy storage device provides emergency power to users, avoiding power outages during fault repair and ensuring power supply reliability.

[0078] In the embodiments of the present application, the energy storage device can be applied to the scenarios mentioned in the above embodiments, and can also be applied to other scenarios. The embodiments of the present application do not specifically limit the specific application scenarios.

[0079] The fire protection method provided by the present application is introduced below in conjunction with the accompanying drawings.

[0080] like Figure 1 As shown, the method includes steps 1100-1300.

[0081] Step 1100: Acquire first state information and second state information, wherein the first state information is obtained based on predetermined environmental parameters in a space defined by an energy storage cabinet and an outside of the battery pack, and the second state information is obtained based on predetermined environmental parameters in an internal space of the battery pack.

[0082] In an embodiment of the present application, the first state information is used to indicate the degree of thermal runaway of the energy storage device, and the second state information is used to indicate the degree of thermal runaway of the battery pack. The first state information is obtained based on predetermined environmental parameters of the space inside the cabinet and the space outside the battery pack. The second state information is obtained based on predetermined environmental parameters of the space inside the battery pack. The predetermined environmental parameters may include parameters such as temperature, smoke concentration, and combustible gas concentration. In addition, the predetermined environmental parameters may also include other parameters, which are not specifically limited here.

[0083] Optionally, thermal runaway of a battery pack may be caused by a battery pack failure, such as a rupture of the diaphragm between the battery anode and the electrolyte. This will cause the battery temperature to rise, resulting in a chain reaction, releasing more energy, and causing the electrolyte in the battery to decompose into flammable gases. Thermal runaway of a battery pack may also be caused by other reasons, such as an internal short circuit in the battery pack, which may also cause thermal runaway of the battery pack. In addition, thermal runaway of a battery pack may also be caused by other reasons, which are not specifically limited here.

[0084] In the embodiments of the present application, the thermal runaway of the energy storage cabin may be caused by the thermal runaway of the battery pack. If the battery pack is in thermal runaway, phenomena such as temperature rise, fire, and smoke generation may occur, causing the temperature of the energy storage cabin to rise, and then causing thermal runaway of the energy storage cabin. The thermal runaway of the energy storage cabin may also be caused by other electrical equipment in the energy storage cabin, such as a short circuit in the power supply system of the energy storage cabin, causing the power supply system to catch fire, and then causing thermal runaway of the energy storage cabin. In addition, the thermal runaway of the energy storage device may also be due to other reasons, which are not specifically limited here.

[0085] When a battery pack experiences thermal runaway, smoke will be generated inside the battery pack. The smoke contains flammable gases, such as volatile organic compounds (VOC), H2, CO, etc. The temperature of the battery pack and the energy storage device will also rise. At the same time, the air pressure inside the battery pack increases, which impacts the pressure relief valve of the battery pack. The pressure relief valve becomes loose or even completely opened, and the smoke is discharged from the battery pack into the energy storage device cabinet.

[0086] A sensor is provided in the energy storage device, which can be used to detect the first state information. The sensor is arranged outside the battery pack in the cabinet. For example, a combustible gas sensor, a smoke sensor, and a temperature sensor. The combustible gas sensor can detect the concentration of combustible gas in the energy storage device, the smoke sensor can detect the concentration of smoke in the energy storage device, and the temperature sensor can detect the temperature in the energy storage device. For example, the sensor for detecting the first state information can be arranged on the top of the energy storage device. In the event of thermal runaway, the smoke and combustible gas in the energy storage device will spread upward. Setting the sensor on the top of the energy storage device can detect the smoke and combustible gas in the energy storage device in a timely manner.

[0087] The battery pack is also equipped with sensors that can be used to detect the concentration of combustible gas in the battery pack, the gas pressure of the battery pack, and the temperature of the battery pack. When the battery pack experiences thermal runaway, a large amount of combustible gas and smoke will first be generated inside the battery pack, and the combustible gas and smoke will open the pressure relief valve. The sensor for the second state information is set inside the battery pack. There are battery cells in the battery pack, and the second state information can be the temperature information of the battery cells. The sensor for detecting the temperature information of the battery cells can be set on the surface of the battery cells.

[0088] The first state information or the second state information may be a specific value or a flag. For example, the first state information may be the concentration value of the combustible gas in the energy storage device, or the concentration of the smoke, or the temperature value, etc. The first state information may also be a flag generated when the concentration of the combustible gas in the energy storage device exceeds a preset concentration value, or a flag generated when the concentration of the smoke exceeds a preset concentration value, etc.

[0089] For another example, the second state information of the battery pack may be the concentration of the combustible gas in the battery pack, or the air pressure of the battery pack, or the temperature of the battery pack. The second state information of the battery pack may also be a flag indicating when the concentration of the combustible gas in the battery pack exceeds a preset concentration, or a flag indicating when the air pressure of the battery pack exceeds a preset air pressure, or a flag indicating when the temperature of the battery pack exceeds a preset temperature. For example, when the second state information is 001, it indicates that the concentration of the combustible gas in the battery pack exceeds the preset concentration. For another example, when the second state information is 010, it indicates that the air pressure of the battery pack exceeds the preset air pressure. For another example, when the second state information is 100, it indicates that the temperature of the battery pack exceeds the preset temperature.

[0090] In the disclosed embodiment, the second status information of each battery pack may be obtained, or the second status information of some battery packs may be obtained.

[0091] Step 1200: Generate a first system-level firefighting instruction according to the first state information, wherein the first system-level firefighting instruction is used to instruct the energy storage device to carry out firefighting inside the energy storage cabinet.

[0092] In the embodiment of the present disclosure, system-level fire instructions for multiple energy storage devices and judgment conditions corresponding to each instruction are pre-set, and the system-level fire instructions for the energy storage device are generated according to whether the first state information meets the judgment condition.

[0093] For example, the fire protection level of the energy storage device is pre-set to include level one and level two. The judgment conditions corresponding to the level one fire protection level of the energy storage device and the judgment conditions corresponding to the level two fire protection level are pre-set. When the first state information of the energy storage device meets the judgment conditions corresponding to the level one fire protection level of the energy storage device, the fire protection level of the energy storage device is determined to be level one. When the first state information of the energy storage device meets the judgment conditions corresponding to the level two fire protection level of the energy storage device, the fire protection level of the energy storage device is determined to be level two.

[0094] Pre-set fire instructions corresponding to the fire level of each energy storage device. Fire instructions may include various measures such as alarm, exhaust ventilation, and fire extinguishing. For example, an alarm bell and an audible and visual alarm may be set in the energy storage device, and an alarm may be sounded by the alarm bell, or an audible and visual alarm may be used to alert staff to handle the situation in a timely manner. The alarm bell and the audible and visual alarm may also be set outside the energy storage device to alert people outside the energy storage device. In addition, fire instructions may also be other measures, which are not specifically limited here.

[0095] An exhaust ventilation device may also be installed in the energy storage device, and the energy storage device may be vented by opening the exhaust ventilation device. The smoke and combustible gas in the energy storage device may be discharged by exhaust, and the temperature of the energy storage device may also be reduced. The fire may also be extinguished by spraying a fire extinguishing agent, for example, multiple nozzles may be provided in the energy storage device, and the fire extinguishing agent may be sprayed through the nozzles, and the fire extinguishing agent may be perfluorohexanone or liquid nitrogen, etc.

[0096] Step 1300: Generate a battery pack-level fire-fighting instruction corresponding to a target level among a plurality of preset battery pack fire-fighting levels according to the second state information, wherein the battery pack-level fire-fighting instruction is to perform fire-fighting on the battery pack.

[0097] Preset multiple fire protection levels of battery packs and judgment conditions corresponding to the fire protection level of each battery pack. Determine the fire protection level of the battery pack according to whether the second state information meets the judgment condition.

[0098] For example, the fire protection level of the battery pack is preset to include level one and level two. The judgment conditions corresponding to the level one fire protection level of the battery pack and the judgment conditions corresponding to the level two fire protection level are preset. When the second state information meets the judgment condition corresponding to the level one fire protection level of the battery pack, the fire protection level of the battery pack is determined to be level one. When the second state information of the battery pack meets the judgment condition corresponding to the level two fire protection level, the fire protection level of the battery pack is determined to be level two.

[0099] Fire instructions corresponding to the fire level of each battery pack are also pre-set. For example, when an alarm occurs in the battery pack, the alarm bell and sound and light alarm set in the energy storage device can be called to alarm. The exhaust ventilation device in the energy storage device can also be opened to exhaust. The fire extinguishing agent can also be sprayed into the battery pack through the nozzle set in the battery pack.

[0100] This embodiment sets fire instructions for the battery pack and the energy storage device respectively, and performs different levels of thermal runaway processing, which can achieve accurate fault location. The corresponding fire protection treatment is performed on the battery pack with thermal runaway, which has a better fire protection effect than the fire protection treatment of the entire energy storage device. Since some devices may be damaged during the fire protection process of the entire energy storage device, property losses can be reduced by performing fire protection treatment inside the battery pack. The fire protection instructions at the energy storage device level can deal with more serious thermal runaway situations, and can also monitor and protect electrical fires in the energy storage device.

[0101] In this embodiment, Figure 2 As shown, the second status information includes volatile organic compound (VOC) concentration information of the battery pack and smoke concentration information of the battery pack.

[0102] In the early stage of thermal runaway, the battery pack temperature rises and the battery pack voltage decreases, which will first produce volatile organic compounds (VOC) gas and smoke. The smoke concentration information and VOC concentration information of the battery pack can reflect the degree of thermal runaway of the battery pack. The more serious the thermal runaway of the battery pack, the higher the VOC concentration and smoke concentration of the battery pack.

[0103] The concentration information in this embodiment can be a specific concentration value, or a flag indicating that the concentration value exceeds a preset value. For example, the smoke concentration information can be 100ppm, or a percentage value can be used to represent the concentration, such as 10%. For another example, the smoke concentration information can also be a binary number 0001, which means that the smoke concentration exceeds 100ppm.

[0104] In this embodiment, step 1300 includes: confirming that the VOC concentration of the battery pack exceeds the first concentration value and the smoke concentration of the battery pack exceeds the second concentration value based on the second status information; and generating a first fire instruction corresponding to the first level of a plurality of preset battery pack fire levels.

[0105] When the VOC concentration of the battery pack exceeds the first concentration value and the smoke concentration of the battery pack exceeds the second concentration value, the battery pack is considered to have thermal runaway. At this time, the battery pack is in the early stage of thermal runaway, and the degree of thermal runaway is not particularly serious. The corresponding fire protection level of the battery pack is level one, and the first fire protection instruction is generated at this time. The first fire protection instruction is the fire protection instruction corresponding to the fire protection level of the battery pack is level one. For example, the first concentration value can be 25%, and the second concentration value can be 20%. The first concentration value and the second concentration value can be determined according to the parameters of the actual battery pack, and are not limited here.

[0106] Specifically, the first fire-fighting instruction includes: instructing the alarm of the energy storage device to sound an alarm.

[0107] The alarm can be an alarm lamp, and when the fire protection level is level 1, the alarm lamp is used to flash an alarm. In addition, the alarm can also be other devices, which are not specifically limited here.

[0108] In this embodiment, Figure 3 As shown, the second status information includes VOC concentration information of the battery pack and carbon monoxide CO concentration information of the battery pack.

[0109] As the thermal runaway of the battery pack intensifies, CO gas will be further generated. And the higher the thermal runaway of the battery pack, the higher the CO concentration of the battery pack. According to the VOC concentration and CO concentration of the battery pack, it can be judged whether the fire protection level of the battery pack reaches level 2.

[0110] Step 1300 includes: confirming, based on the second status information, that the VOC concentration of the battery pack exceeds a first concentration value and the CO concentration of the battery pack exceeds a third concentration value; and generating a second fire instruction corresponding to a second level among a plurality of preset battery pack fire levels.

[0111] If the VOC concentration of the battery pack exceeds the first concentration value, and the CO concentration of the battery pack exceeds the third concentration value, then the fire protection level of the battery pack is considered to reach level 2, and a second fire protection instruction is generated. The second fire protection instruction is a fire protection instruction corresponding to the fire protection level of the battery pack being level 2. For example, the first concentration value can be 25%, and the second concentration value can be 20%. In addition, the first concentration value and the second concentration value can also be other values, which are not limited here.

[0112] This embodiment can be decoupled and implemented separately. Figure 4 As shown, this embodiment can also be implemented together with the embodiment corresponding to the first fire instruction, and the first fire instruction is generated before the second fire instruction is generated. When the first fire instruction has been generated, if the CO concentration of the battery pack exceeds the third concentration value, then the second fire instruction is generated.

[0113] In one embodiment, the second fire-fighting instruction includes: instructing a ventilation device of the energy storage device to turn on.

[0114] Due to the high concentration of VOC and CO in the battery pack, these gases will further aggravate the thermal runaway of the battery pack. In order to eliminate the thermal runaway of the battery pack in time, these gases need to be discharged as soon as possible. At this time, the ventilation device of the energy storage device is turned on. For example, the ventilation device can be an exhaust fan.

[0115] In another embodiment, the second fire fighting instruction includes: instructing an alarm of the energy storage device to sound an alarm, and instructing a ventilation device of the energy storage device to turn on.

[0116] When the ventilation device of the energy storage device is turned on, the alarm of the energy storage device is also set to sound. For example, when the fire level is level 2, the alarm can be used to sound the alarm. Compared with flashing lights, it is easier for staff to hear the sound and be able to know the thermal runaway state of the battery pack in time.

[0117] In this embodiment, Figure 5 As shown, the second state information includes VOC concentration information of the battery pack, CO concentration information of the battery pack, and temperature information of the battery pack.

[0118] As the thermal runaway of the battery pack intensifies, the concentration of combustible gas and smoke in the battery pack increases. Due to the high temperature of smoke and combustible gas, the temperature of the battery pack will rise under the action of smoke and combustible gas. The VOC concentration, CO concentration and temperature of the battery pack can be used to determine whether the battery pack has reached the third level alarm.

[0119] Step 1300 includes: confirming, based on the second status information, that the VOC concentration of the battery pack exceeds a first concentration value, the smoke concentration of the battery pack exceeds a second concentration value, and the CO concentration of the battery pack exceeds a third concentration value; and generating a third fire instruction corresponding to a third level among a plurality of preset battery pack fire levels.

[0120] If the VOC concentration of the battery pack exceeds the first concentration value, the smoke concentration of the battery pack exceeds the second concentration value, and the CO concentration of the battery pack exceeds the third concentration value, then the fire level of the battery pack is considered to have reached level three, and a third fire instruction is generated. The third fire instruction is a fire instruction corresponding to the third level alarm of the battery pack.

[0121] This embodiment can be decoupled and implemented separately. Figure 6 As shown, this embodiment can also be implemented together with the embodiment corresponding to the first fire instruction and the embodiment corresponding to the second fire instruction, and the first fire instruction and the second fire instruction are generated before the third fire instruction is generated. First, when the VOC concentration of the battery pack exceeds the first concentration value and the smoke concentration of the battery pack exceeds the second concentration value, the first fire instruction is generated. Then, when the first fire instruction has been generated and the CO concentration of the battery pack exceeds the third concentration value, the second fire instruction is generated. Finally, when the second fire instruction has been generated and the temperature of the battery pack exceeds the first temperature value, the third fire instruction is generated.

[0122] In one implementation, the third firefighting instruction includes: instructing the energy storage device to perform fire extinguishing processing.

[0123] When the third alarm is reached, the degree of thermal runaway is already serious and fire extinguishing is required. For example, fire extinguishing can be carried out by spraying fire extinguishing agent. In order to ensure the fire extinguishing effect, the ventilation device can be turned off. After the ventilation device is turned off, the fire extinguishing agent can be prevented from being discharged to the outside of the energy storage device, and the concentration of the fire extinguishing agent in the energy storage device can be ensured to improve the fire extinguishing effect.

[0124] In another embodiment, an alarm device of the energy storage device is instructed to sound an alarm, and the energy storage device is instructed to perform fire extinguishing processing.

[0125] While extinguishing the fire, the alarm of the energy storage device is also used to sound an alarm. For example, when the fire level is level three, an audible and visual alarm can be used to sound and flash at the same time.

[0126] In this embodiment, Figure 7 As shown, the first state information includes smoke concentration information of the energy storage device.

[0127] When a battery pack experiences thermal runaway, smoke will be generated inside the battery pack, and the smoke will contain flammable gas. At the same time, the air pressure inside the battery pack will increase, causing an impact on the pressure relief valve of the battery pack, which will become loose or even completely opened, and the smoke will be discharged from the battery pack into the energy storage device cabinet, causing the smoke concentration of the energy storage device to increase. The degree of thermal runaway of the energy storage device can be judged by the smoke concentration of the energy storage device.

[0128] Step 1200 includes: confirming, according to the first state information, that the smoke concentration of the energy storage device exceeds a fourth concentration value; and generating a fourth firefighting instruction, wherein the system-level firefighting instruction includes the fourth firefighting instruction.

[0129] like Figure 7 As shown, if the smoke concentration of the energy storage device exceeds the fourth concentration value, it is considered that the fire protection level of the energy storage device reaches level one, and a fourth fire protection instruction is generated. The fourth fire protection instruction is a fire protection instruction corresponding to when the fire protection level of the energy storage device is level one.

[0130] This embodiment can be decoupled and implemented separately. Figure 8 As shown, this embodiment can also be implemented together with the embodiment corresponding to the fire instruction at the battery pack level. The fourth fire instruction can be generated when the first fire instruction has been generated and the smoke concentration of the energy storage device exceeds the fourth concentration value. The fourth fire instruction can also be generated when the second fire instruction has been generated and the smoke concentration of the energy storage device exceeds the fourth concentration value. The fourth fire instruction can also be generated when the third fire instruction has been generated and the smoke concentration of the energy storage device exceeds the fourth concentration value.

[0131] In one implementation, the fourth firefighting instruction includes: instructing a ventilation device of the energy storage device to turn on.

[0132] Since the smoke concentration in the energy storage device is relatively high, it is necessary to open the ventilation device to discharge the smoke in the energy storage device.

[0133] In another embodiment, the fourth fire-fighting instruction includes: instructing an alarm of the energy storage device to sound an alarm, and instructing a ventilation device of the energy storage device to turn on.

[0134] When the ventilation device is turned on to exhaust smoke, the alarm of the energy storage device can also be used to sound an alarm. For example, the alarm light can be used to flash to sound an alarm. The color and flashing mode of the light can be distinguished from the fire protection level of the battery pack, which is level one. For example, the red light flashes when the fire protection level of the battery pack is level one, and the yellow light flashes when the fire protection level of the energy storage device is level one.

[0135] In this embodiment, Fig. 9 As shown, the first state information includes smoke concentration information of the energy storage device and temperature information of the energy storage device.

[0136] As the smoke concentration in the energy storage device increases, the temperature of the energy storage device will increase. The smoke concentration and temperature of the energy storage device can be used to determine whether the fire protection level of the energy storage device reaches level 2.

[0137] Step 1200 includes: confirming, based on the first state information, that the smoke concentration of the energy storage device exceeds a fourth concentration value, and that the temperature of the energy storage device exceeds a first temperature value; and generating a fifth fire instruction, wherein the system-level fire instruction includes the fifth fire instruction.

[0138] like Fig. 9 As shown, if the smoke concentration of the energy storage device exceeds the fourth concentration value and the temperature of the storage device exceeds the first temperature value, it is considered that the fire protection level of the energy storage device reaches level two, and a fifth fire protection instruction is generated. The fifth fire protection instruction is a fire protection instruction corresponding to the fire protection level of the energy storage device being level two.

[0139] This embodiment can be decoupled and implemented separately. Fig.10 As shown, this embodiment can also be implemented together with the embodiment corresponding to the fourth fire instruction. Fig.11 As shown, this embodiment can also be implemented together with the embodiment corresponding to the fire fighting instruction at the battery pack level.

[0140] In one embodiment, the fifth firefighting instruction includes: instructing the ventilation device of the energy storage device to be closed and then perform fire extinguishing processing.

[0141] When the fire protection level of the energy storage device reaches level 2, the energy storage device needs to be extinguished. In order to ensure the fire extinguishing effect, the ventilation device can be turned off while extinguishing the fire.

[0142] In another embodiment, the fourth firefighting instruction includes: instructing an alarm of the energy storage device to sound an alarm, and instructing a ventilation device of the energy storage device to shut down and then perform fire extinguishing.

[0143] When extinguishing the fire, an alarm can also be issued, for example, by using an audible and visual alarm.

[0144] In this embodiment, the fire protection processing method further includes: generating a second system-level fire protection instruction according to the first state information; the second system-level fire protection instruction is used to instruct an external fire protection device to perform fire protection on the energy storage cabinet from outside the energy storage cabinet.

[0145] A fire controller may be provided outside the energy storage device. The fire controller may obtain the first state information of the energy storage device. For example, if a plurality of energy storage devices are provided in an energy storage station, if a dedicated fire controller is provided in each energy storage device to control the fire-fighting action of the energy storage device, the cost of the energy storage device will increase. Considering the cost, only one high-performance fire controller may be provided in the entire energy storage station. The fire controller may manage the fire-fighting systems of all energy storage devices. After the first state information is detected by the sensor of each energy storage device, the first state information is sent to the fire controller outside the energy storage device, and the fire controller generates a second system-level fire-fighting instruction. The energy storage device is extinguished by a fire-fighting device outside the energy storage device. For example, a fire-fighting agent is sprayed on the energy storage device by a fire-fighting device outside the energy storage device.

[0146] An embodiment of the present application provides an energy storage device, including an energy storage cabinet, in which at least one battery pack is arranged; the energy storage device is provided with a controller, a first monitoring module and a second monitoring module; the first monitoring module includes a plurality of sensors arranged inside the energy storage cabinet and outside the battery pack; the second monitoring module includes a plurality of sensors arranged inside the battery pack; the controller includes a processor and a memory, the memory stores a program or instruction that can be run on the processor, and when the program or instruction is executed by the processor, the steps of the fire treatment method as described in any embodiment of the present invention are implemented.

[0147] In one example, the first monitoring module includes a first smoke sensor and a first temperature sensor, the first smoke sensor is used to detect the smoke concentration of the energy storage device, and the first temperature sensor is used to detect the temperature of the energy storage device.

[0148] In one example, the second monitoring module includes a second smoke sensor, a combustible gas sensor and a second temperature sensor, the first smoke sensor is used to detect the smoke concentration of the battery pack, the combustible gas sensor is used to detect the combustible gas concentration of the battery pack, and the second temperature sensor is used to detect the temperature of the battery pack.

[0149] like Figure 12-14 As shown, the energy storage device is provided with a central control host 8, sensors and multiple battery compartments, and the controller of the energy storage device can be the central control host 8. The battery compartment includes a regional control host 4, multiple battery packs and a second monitoring module 1 corresponding to each battery pack. The second monitoring module 1 is used to monitor the status information of the corresponding battery pack and send the status information of the battery pack to the regional control host 4.

[0150] See also Fig.14 As shown, the central control host and the regional control host can be connected to the energy management system (EMS) and the controller (Embedded Microcontroller Unit, EMCU) in the battery management system (BMS) through RS485 / CAN / LAN bus, etc., so as to further combine the data of the EMS system and the BMS system for fire control.

[0151] The regional control host 4 is used to determine the fire protection level corresponding to the battery pack according to the status information of the battery pack, and send an alarm signal corresponding to the fire protection level of the battery pack to the central control host 8. The sensor is used to detect the status information of the energy storage device and send the status information of the energy storage device to the central control host 8. The central control host 8 is used to determine the fire protection level corresponding to the energy storage device according to the status information of the energy storage device. The central control host 8 is used to generate a corresponding fire protection instruction according to the fire protection level corresponding to the battery pack and the fire protection level corresponding to the energy storage device.

[0152] See also Fig.13As shown, the energy storage cabinet is divided into multiple battery compartments 17 and multiple battery clusters 18, each battery cluster 18 includes three battery packs 16, and a fire hose 19 is laid in the energy storage cabinet. The fire hose 19 is first connected to each battery compartment 17 through a three-way valve 20, and then connected to each battery pack 16. An electric ball valve 2 is provided in each battery compartment 17, and the electric ball valve 2 is used to control the conduction of the fire protection pipeline of the battery compartment. When the electric ball valve 2 is closed, it is impossible to spray and extinguish the fire on any battery pack 16 in the battery compartment 17. A corresponding puncture valve 3 is also provided for each battery pack, and when the puncture valve 3 is closed, it is impossible to spray and extinguish the fire on the corresponding battery pack. A regional control host 4 is provided in each battery compartment 17, and the regional control host 4 is the controller of the battery compartment 17. Multiple battery packs 16 and a second monitoring module 1 corresponding to each battery pack 16 are provided in each battery compartment 17. The second monitoring module 1 can be used to monitor the status information of the battery pack 16, such as monitoring the voltage, temperature, air pressure and other status information of the battery pack 16. When a failure occurs in the central control host 8 , the regional control hosts 4 in each battery compartment 17 may generate a fire-fighting instruction at the battery pack level according to the status data of the battery pack detected by the second monitoring module 1 .

[0153] See also Fig.12 As shown, a ventilation device 9 is provided in the energy storage cabinet, which is used to exhaust and ventilate from the inside of the energy storage device to the outside of the energy storage device. When the ventilation device 9 is working, the deflation indicator light 15 lights up. A first temperature sensor 6 and a first smoke sensor 7 are deployed in the energy storage cabinet. The energy storage device is provided with an alarm 14 and an audible and visual alarm 13 for issuing an alarm. The energy storage device can also be provided with a display host 10 for displaying the current status of the energy storage device. After the user presses the manual button 11, the ventilation device 9 can be controlled to work or shut down through the gas start and stop button 5. In addition, a manual-automatic converter 12 is also provided. When the manual-automatic converter 12 is switched to the manual state, the sprinkler fire extinguishing device can be manually controlled to work.

[0154] The display host 10 can display alarm information according to the fire protection level of the battery pack and the fire protection level of the energy storage device. For example, when the battery pack alarms, the location, number and other information of the battery pack with the problem can be displayed, and the temperature, voltage and other status information of the battery pack can also be displayed. Under different fire protection levels, the status information of the battery pack is also different. For example, the higher the fire protection level, the higher the temperature of the battery pack. The display host 10 can also display the alarm information of the energy storage device. For example, the status of the energy storage device.

[0155] The second monitoring module 1 can send the status information of the battery pack to the regional control host 4, and the regional control host 4 determines the fire protection level of the battery pack. For example, the fire protection levels of multiple battery packs and the judgment conditions corresponding to each fire protection level can be pre-set, and the fire protection level of the battery pack is determined according to whether the status information of the battery pack meets the judgment conditions. After determining the fire protection level of the battery pack, the second monitoring module 1 sends a corresponding alarm signal to the central control host 8. For example, if the second monitoring module 1 determines that the fire protection level of the battery pack is level one, then a signal indicating that the fire protection level is level one is sent to the central control host 8. If the second monitoring module 1 determines that the fire protection level of the battery pack is level two, then a signal indicating that the fire protection level is level two is sent to the central control host 8. The higher the fire protection level of the battery pack, the more serious the thermal runaway of the battery pack.

[0156] The sprinkler fire extinguishing device includes a plurality of atomizing nozzles arranged at a preset distance on the top of the energy storage device. It is used to spray the entire energy storage device for fire extinguishing. The number of atomizing nozzles can be determined according to the size of the energy storage device and the spray diameter of the atomizing nozzles. The larger the energy storage device, the more atomizing nozzles need to be set.

[0157] In this embodiment, a water fire fighting device is also provided in the energy storage device, and the water fire fighting device includes a water fire fighting pipeline arranged on the top of the energy storage device and a plurality of nozzles arranged on the water fire fighting pipeline. When the fire fighting level corresponding to the energy storage device is level 2, the central control host controls the water fire fighting device to spray water into the energy storage device.

[0158] The water fire fighting device is used as a backup fire fighting device. When the fire situation cannot be eliminated in time by spraying fire extinguishing agent alone, the water fire fighting device is turned on to spray water into the energy storage device to extinguish the fire, so as to avoid further deterioration of the fire.
