However, these firefighting strategies are based on only a single signal (such as a temperature signal) to monitor system thermal runaway, and none of them can accurately locate thermal runaway faults. Summary of the invention

And the corresponding firefighting treatment is performed on the battery pack with thermal runaway, which has a better firefighting effect compared to the firefighting treatment of the entire energy storage device. Since some devices may be damaged during the firefighting process of the entire energy storage device, property losses can be reduced by performing firefighting treatment inside the battery pack. The firefighting strategy at the energy storage device level can cope with more serious thermal runaway situations, and can also monitor and protect electrical fires in the energy storage device.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] like Figure 1As shown, this embodiment provides a fire treatment method. The method is applied to an energy storage device, which includes a cabinet and at least one battery pack arranged in the cabinet. An energy storage device is a device for storing electrical energy or other energy sources. The energy storage device can be an energy storage cabin, 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.

[0065] First, specific scenarios in which the energy storage device provided in this application may be deployed are introduced.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] The fire protection method provided by the present application is introduced below in conjunction with the accompanying drawings.

[0071] like Figure 1 The fire protection method provided in this application includes steps 1100-1300.

[0072] Step 1100: Obtain first state information and second state information.

[0073] In an embodiment of the present application, the first state information can be used to indicate the degree of thermal runaway of the energy storage device. The second state information can be used to indicate the degree of thermal runaway of the battery pack. In the energy storage system, the degree of thermal runaway can be divided into situations such as not out of control but about to be out of control, already out of control, etc. according to the severity. For example, the current of the battery suddenly begins to increase rapidly, indicating that the battery currently has a high risk of thermal runaway but has not yet lost control. For example, the battery fails due to a short circuit, indicating that the battery is already out of control at this time. For example, the battery pack swells, indicating that the battery currently has a risk of thermal runaway. For example, the total battery capacity of the energy storage device suddenly begins to decrease, indicating that the energy storage device has a risk of thermal runaway but has not yet lost control. For example, a large amount of flammable gas emerges from the energy storage device, indicating that the energy storage device has lost control. As the degree of thermal runaway continues to develop, the large amount of heat generated inside the battery will intensify the reaction process, thereby causing system failure in the field of energy storage technology, and even causing serious consequences such as explosions and fires. In the embodiments of the present disclosure, when the degree of thermal runaway of the energy storage device or battery pack is not out of control but is about to be out of control, or has already been out of control, a fire protection strategy is provided to reduce the risk of thermal runaway of the energy storage device or battery pack and improve the safety of the energy storage device or battery pack.

[0074] 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.

[0075] 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.

[0076] When the battery pack experiences thermal runaway, smoke will be generated inside the battery pack. The smoke contains flammable gases, such as volatile organic compounds (VOC), hydrogen H2, carbon monoxide 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, causing the pressure relief valve to loosen or even be completely opened, and the smoke is discharged from the battery pack into the energy storage device cabinet.

[0077] 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, a temperature sensor, etc. 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 is arranged on the top of the energy storage cabin. In the event of thermal runaway, the smoke and combustible gas in the energy storage cabin will spread upward. Setting the sensor on the top of the energy storage cabin can detect the smoke and combustible gas in the energy storage cabin in time.

[0078] 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.

[0079] 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.

[0080] For another example, the second state information of the battery pack may be the concentration value of the combustible gas in the battery pack, such as 300ppm, or the air pressure value of the battery pack, such as 100kPa, or the temperature value of the battery pack, such as 50°C. 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.

[0081] In the embodiment of the present application, the second status information of each battery pack may be obtained, or the second status information of some battery packs may be obtained.

[0082] Step 1200: Generate a system-level fire protection strategy according to the first state information, wherein the system-level fire protection strategy is used to instruct the energy storage device to perform fire protection inside a cabinet of the energy storage device.

[0083] In the embodiment of the present application, system-level fire protection strategies for multiple energy storage devices and judgment conditions corresponding to each strategy are preset, and the system-level fire protection strategy is generated according to whether the first state information meets the judgment condition.

[0084] For example, the alarm levels of the energy storage device are pre-set to include level one and level two, and corresponding firefighting strategies are set for the level one alarm and level two alarm of the energy storage device respectively. The judgment conditions corresponding to the level one alarm and level two alarm of the energy storage device are pre-set. When the first state information meets the judgment conditions corresponding to the level one alarm of the energy storage device, the alarm level of the energy storage device is determined to be level one. When the first state information meets the judgment conditions corresponding to the level two alarm of the energy storage device, the alarm level of the energy storage device is determined to be level two.

[0085] Pre-set the firefighting strategy corresponding to each alarm level of the energy storage device. The firefighting strategy 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 the 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, the firefighting strategy may also be other measures, which are not specifically limited here.

[0086] 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.

[0087] Step 1300: Generate a battery pack-level fire protection strategy according to the second status information, wherein the battery pack-level fire protection strategy is used to instruct the energy storage device to perform fire protection inside the battery pack.

[0088] The alarm levels of multiple battery packs and the judgment conditions corresponding to the alarm level of each battery pack are preset, and the alarm level of the energy storage device is determined according to whether the second state information meets the judgment condition.

[0089] For example, the alarm level of the battery pack is preset to include level one and level two. The judgment conditions corresponding to the level one alarm and the judgment conditions corresponding to the level two alarm of the battery pack are preset. When the second state information meets the judgment conditions corresponding to the level one alarm of the battery pack, the alarm level of the battery pack is determined to be level one. When the second state information meets the judgment conditions corresponding to the level two alarm, the alarm level of the battery pack is determined to be level two.

[0090] Similarly, fire fighting strategies corresponding to each alarm level of the battery pack are 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 sound the alarm. The exhaust ventilation device in the energy storage device can also be turned on to exhaust the air. The fire extinguishing agent can also be sprayed into the battery pack through the nozzle set in the battery pack. In addition, the fire fighting strategy can also be other measures, which are not limited here.

[0091] This embodiment performs different levels of thermal runaway processing by setting fire protection strategies for the battery pack and the energy storage device respectively. The fire protection strategy at the battery pack level can accurately locate the fault. 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 strategy at the energy storage device level can cope with more serious thermal runaway situations, and can also monitor and protect electrical fires in the energy storage device.

[0092] In this embodiment, Figure 2 As shown, the second status information includes at least one of the first temperature information of the battery pack, the first air pressure information of the battery pack, the combustible gas concentration information of the battery pack, the first smoke concentration information of the battery pack, and the sound information of the battery pack.

[0093] In one example, step 1300 includes steps 1310 - 1320 .

[0094] Step 1310: When the second status information satisfies at least one first preset condition, execute a first fire protection strategy at the battery pack level, wherein the first preset condition includes: the first temperature information of the battery pack indicates that the temperature of the battery pack exceeds a first temperature value, the first air pressure information of the battery pack indicates that the air pressure of the battery pack exceeds a first air pressure value, the combustible gas concentration information of the battery pack indicates that the combustible gas concentration of the battery pack exceeds a first concentration value, the first smoke concentration information of the battery pack indicates that the smoke concentration of the battery pack exceeds a second concentration value, and the sound information of the battery pack indicates that the volume value in the battery pack exceeds a first volume value.

[0095] There are multiple battery cells in the battery pack, and a pressure relief valve is installed on the battery cells. After thermal runaway occurs, the gas in the battery cell will flush the pressure relief valve open, causing the pressure relief valve to loosen. In this embodiment, a sound sensor is provided in the battery pack, and the sound sensor is used to detect whether the pressure relief valve of the battery pack is loose. When the pressure relief valve is loose, a sound will be emitted, and the sound of the loose pressure relief valve can be detected by the sound sensor. When the sound information of the loose pressure relief valve exceeds the first volume value, the alarm level of the battery pack is determined to be level one. For example, the first volume value can be 30dB. In addition, the first volume value can also be other values, which are not limited here.

[0096] Since the temperature of the battery pack will gradually increase after thermal runaway occurs, when the temperature of the battery pack exceeds the first temperature value, the alarm level of the battery pack is determined to be level 1. For example, the first temperature value may be 75° C. In addition, the first temperature value may also be other values, which are not specifically limited here.

[0097] When the battery pack experiences thermal runaway, the smoke concentration inside the battery pack increases. When it is detected that the smoke concentration inside the battery pack exceeds the second concentration value, the alarm level of the battery pack is determined to be level one. At the same time, the concentration of combustible gas in the battery pack will also increase, and whether the alarm level of the battery pack is level one can also be determined based on the concentration of combustible gas in the battery pack. For example, whether the alarm level of the battery pack is level one can be determined based on the concentration of VOC in the battery pack or the concentration of CO in the battery pack. 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.

[0098] In this embodiment, the first fire fighting strategy includes at least one of the following: instructing an alarm of the energy storage device to sound an alarm, cutting off power supply to an air conditioner of the energy storage device, and controlling the energy storage device to shut down.

[0099] By sending out an alarm through an alarm, the staff can be notified to evacuate the thermal runaway site in time to ensure personal safety. For example, the alarm is an alarm light, and when the alarm level is level 1, the alarm light flashes to give an alarm. In addition, the alarm can also be other devices, which are not limited here.

[0100] By cutting off the power supply to the air conditioner of the energy storage device, the impact of thermal runaway on the air conditioner can be reduced, and the loss can be reduced. Similarly, shutting down the energy storage device can also reduce the loss caused by thermal runaway.

[0101] In the disclosed embodiment, the operation panel can be deployed at the location of the energy storage device, and the control terminal can be deployed remotely. The control terminal can be a user's mobile phone terminal, or a control terminal that only receives information. In addition, the control terminal can also be other devices, which are not specifically limited here.

[0102] In this embodiment, Figure 3 and Figure 4 As shown, the second status information includes at least the second temperature information of the battery pack, the second air pressure information of the battery pack, the CO concentration information of the battery pack and the second smoke concentration information of the battery pack, the CO concentration information of the battery pack and the VOC concentration information of the battery pack, or one of the VOC concentration information of the battery pack and the second smoke concentration information of the battery pack.

[0103] Step 1300 includes: when the second state information satisfies a second preset condition, executing a second fire protection strategy at the battery pack level.

[0104] The second preset condition is the condition corresponding to the battery pack secondary alarm.

[0105] The second preset condition may include: second temperature information of the battery pack indicates that the temperature of the battery pack exceeds a second temperature value, wherein the second temperature value is higher than the first temperature value.

[0106] After the battery pack's first level alarm, if the thermal runaway of the battery pack becomes more serious, the temperature of the battery pack will further increase. For example, the first temperature value is 70 degrees Celsius and the second temperature value is 85 degrees Celsius. When the temperature of the battery pack exceeds 70 degrees Celsius and is less than 85 degrees Celsius, the alarm level of the battery pack is considered to be level one. When the temperature of the battery pack exceeds 85 degrees Celsius, the alarm level of the battery pack is considered to be level two. In addition, the first temperature value and the second temperature value can also be other values, which are not limited here.

[0107] The second preset condition may include: the second air pressure information of the battery pack indicates that the air pressure of the battery pack exceeds a second air pressure value, wherein the second air pressure is higher than the first air pressure value.

[0108] Similarly, after the battery pack's first level alarm, if the battery pack's thermal runaway becomes more serious, the battery pack's air pressure will further increase. For example, the first air pressure value is 1.2 times the atmospheric pressure, and the second air pressure value is 1.5 times the atmospheric pressure. When the battery pack's air pressure exceeds 1.2 times the atmospheric pressure and is less than 1.5 times the atmospheric pressure, the battery pack's alarm level is considered to be level one. When the battery pack's air pressure exceeds 1.5 times the atmospheric pressure, the battery pack's alarm level is considered to be level two.

[0109] The second preset condition may include: the CO concentration information of the battery pack indicates that the CO concentration of the battery pack exceeds the first concentration value and the second smoke concentration information of the battery pack indicates that the smoke concentration of the battery pack exceeds the second concentration value.

[0110] The second preset condition may include: the CO concentration information of the battery pack indicates that the CO concentration of the battery pack exceeds the first concentration value and the VOC concentration information of the battery pack indicates that the VOC concentration of the battery pack exceeds the first concentration value.

[0111] The second preset condition may include: the second smoke concentration information of the battery pack indicates that the smoke concentration of the battery pack exceeds the second concentration value, and the VOC concentration information of the battery pack indicates that the VOC concentration of the battery pack exceeds the first concentration value.

[0112] like Figure 3 As shown, this embodiment can be implemented together with the embodiment corresponding to the first fire protection strategy at the battery pack level. Figure 4 As shown, this embodiment can also be decoupled and implemented separately.

[0113] This embodiment sets multiple battery pack alarm judgment conditions and comprehensively judges the alarm level of the battery pack based on the multiple judgment conditions, so that the battery pack alarm can be judged more accurately. At the same time, the first-level alarm of the battery pack is judged based on the loose state of the pressure relief valve of the battery pack. The pressure relief valve will be loose in the early stage of thermal runaway of the battery pack, which can achieve early warning, timely discover the thermal runaway of the battery pack, and reduce the loss caused by the thermal runaway of the battery pack.

[0114] In this embodiment, the second fire fighting strategy includes at least one of the following: instructing an alarm of the energy storage device to sound an alarm, and spraying a fire extinguishing agent into the battery pack.

[0115] The alarm used when the alarm level of the battery pack is level 2 may be the same alarm as the alarm used when the alarm level of the battery pack is level 1, or may be a different alarm.

[0116] The secondary alarm of the battery pack is more serious than the primary alarm of the battery pack, and different alarms can be used for alarm. For example, when the alarm level of the battery pack is level 1, the alarm light is used to flash the alarm. For example, when the alarm level of the battery pack is level 2, the sound and light alarm is used to alarm through sound and light at the same time. Users can know the degree of thermal runaway of the battery pack based on the alarm situation.

[0117] When the battery pack alarm is in the second level, the battery pack temperature is high and the battery pack may have caught fire. It is necessary to spray fire extinguishing agent on the battery pack to extinguish the fire and reduce the temperature of the battery pack.

[0118] The present invention is used to instruct to spray the fire extinguishing agent directly to the battery pack when the second fire fighting strategy is generated by the battery pack, which has a better fire extinguishing effect compared with cabin-level spraying.

[0119] In this embodiment, Figure 5As shown, the first state information includes at least one of the third temperature information of the energy storage device, the third smoke concentration information of the energy storage device, and the first concentration information of the combustible gas of the energy storage device.

[0120] Step 1200 includes: when the first state information satisfies any third preset condition, generating a system-level third fire protection strategy, and the third preset condition includes: the third temperature information of the energy storage device indicates that the temperature of the energy storage device exceeds a third temperature value, the third smoke concentration information of the energy storage device indicates that the smoke concentration of the energy storage device exceeds a third concentration value, and the first concentration information of the combustible gas of the energy storage device indicates that the combustible gas concentration of the energy storage device exceeds a fourth concentration value.

[0121] If the first state information of the energy storage device meets any one of the third preset conditions, it is considered that the energy storage device has a first-level alarm. For example, when the temperature in the energy storage device exceeds the third temperature value, the energy storage device has a first-level alarm. For another example, when the smoke concentration in the energy storage device exceeds the third concentration value, the energy storage device has a first-level alarm. Here, the first state information meets any one of the third preset conditions, which means that the first state information meets one of the three third preset conditions.

[0122] This embodiment can be implemented separately and decoupled. This embodiment can also be implemented together with the embodiment corresponding to the fire protection strategy at the battery pack level.

[0123] In this embodiment, the third fire fighting strategy includes: instructing the alarm of the energy storage device to sound an alarm, and / or turning on the exhaust ventilation device of the energy storage device.

[0124] When the energy storage device alarms at the first level, the alarm is sounded through the alarm. The alarm used for the battery pack alarm can be reused to save costs. When the energy storage device alarms at the first level, the exhaust ventilation device can also be turned on to ventilate the smoke and combustible gas in the energy storage device, thereby eliminating thermal runaway.

[0125] In this embodiment, step 1200 includes: when the first state information satisfies any two of the third preset conditions, generating a fourth fire protection strategy at the system level.

[0126] like Figure 6 As shown, if the first state information satisfies two or three third preset conditions, it is considered that the thermal runaway situation is relatively serious and the energy storage device issues a level 2 alarm.

[0127] In this embodiment, the fourth fire fighting strategy includes: instructing the alarm of the energy storage device to sound an alarm, cutting off the power supply of the air conditioner of the energy storage device, controlling the energy storage device to shut down, and / or closing the exhaust ventilation device of the energy storage device and spraying a fire extinguishing agent into the energy storage device after a first preset time.

[0128] When the energy storage device sounds a level 1 alarm, the exhaust ventilation device is turned on. The smoke and flammable gas in the energy storage device are discharged through the exhaust ventilation device, and the energy storage device is cooled down at the same time. At this time, the alarm can also be used to alert the staff to handle it as soon as possible.

[0129] When the energy storage device sounds a level 2 alarm, it indicates that the thermal runaway situation is already quite serious. At this time, the alarm is used to alert the staff, reminding them to stay away from the energy storage device. At the same time, the energy storage device is shut down and the fire extinguishing agent is sprayed on the energy storage device. Since the fire extinguishing agent is sprayed in the form of gas or atomization, in order to ensure the fire extinguishing effect, it is necessary to close the exhaust ventilation device when spraying the fire extinguishing agent to prevent the fire extinguishing agent from being discharged from the energy storage device by the exhaust ventilation device. Wait for a delay time before spraying the fire extinguishing agent, such as 30 seconds, to allow the staff to leave and improve personal safety. At the same time, the alarm of the energy storage device can also be rechecked during the delay time to avoid false alarms.

The second nozzles 9 are used to spray the fire extinguishing agent into the energy storage device. The second nozzles 9 are arranged on the top of the energy storage device.

[0141] The energy storage device is also provided with an exhaust ventilation device 6. For example, the exhaust ventilation device 6 can be an exhaust fan. A plurality of exhaust fans can be provided according to the size of the energy storage device.
