The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] Embodiment 1

[0035] Figure 1 A schematic diagram of a battery compartment emergency treatment method is shown as an example. Figure 1 As shown, the method includes:

[0036] Step 101, obtaining a thermal runaway state of a battery pack in a battery compartment, where the thermal runaway state indicates whether the battery pack has thermal runaway; and obtaining a current temperature of the battery compartment;

[0037] Step 102: Determine the current warning level according to the current temperature and thermal runaway state of the battery compartment;

[0038] Step 103: Execute corresponding emergency protection measures according to the current warning level.

[0039] Specifically, this application is used to perform emergency treatment and protection on the battery compartment; first, the thermal runaway state of the battery pack is obtained. The thermal runaway state obtained in this example indicates whether the battery pack has thermal runaway; in actual applications, thermal runaway of the battery pack refers to the phenomenon that the battery pack generates a large amount of heat due to the runaway of the internal electrochemical reaction without the action of an external heat source, which in turn causes the battery temperature to rise sharply; this phenomenon is often accompanied by the chain start of complex chemical reactions inside the battery, such as the oxidation decomposition of the electrolyte, the rupture of the solid electrolyte interface membrane, the thermal decomposition of the positive electrode material, etc., which may eventually cause serious consequences such as combustion and explosion. At the same time, the current temperature value of the battery compartment is obtained. The current temperature of the battery compartment refers to the temperature value at the location outside the battery pack and inside the battery compartment; according to the obtained thermal runaway state of the battery pack and the current temperature value of the battery compartment, the current warning level is determined; the corresponding emergency protection treatment measures are executed according to the determined warning level. Different thermal runaway states and different battery compartment temperatures correspond to different warning levels; therefore, different warning levels correspond to different emergency protection measures. Emergency protection measures for battery compartments mainly refer to a series of preventive, response and disposal measures taken to ensure personnel safety and reduce property losses when the battery compartment faces potential safety risks or emergencies. In this example, the current warning level is determined based on the thermal runaway state of the battery pack in the battery compartment and the current temperature of the battery compartment. Corresponding emergency protection measures are formulated according to different warning levels, which improves the accuracy of warning level determination and further improves the effectiveness of the emergency protection measures implemented.

[0040] Furthermore, a temperature sensor is provided in the battery compartment; obtaining the current temperature of the battery compartment includes:

[0041] The temperature currently collected by the temperature sensor is obtained as the current temperature of the battery compartment.

[0042] The battery compartment of the present application includes a temperature detector, which is used to detect the temperature of the entire battery compartment; when the current temperature of the battery compartment needs to be obtained, the temperature collected by the temperature detector can be obtained as the current temperature of the battery compartment. In practical applications, a temperature detector, also known as a point-type temperature-sensitive fire detector, is a fire detector that is mainly used to respond to temperature changes around a certain point or a certain line in the warning range; the working principle of the temperature detector is based on the sensitivity of thermistors to temperature changes. When a fire occurs, the combustion of substances releases a large amount of heat, causing the surrounding temperature to rise sharply. The thermistor in the detector can sense this temperature change and convert it into an electrical signal; when the temperature reaches or exceeds the set threshold, the detector will trigger an alarm and transmit the signal to the relevant fire alarm system. In this example, the temperature of the battery compartment is detected using a temperature detector, which improves the accuracy of the battery compartment temperature detection.

[0043] Furthermore, when the battery pack is in a state of thermal runaway, the battery pack needs to be cooled; accordingly, as an example, a cooling device is provided in the battery pack; the method further includes:

[0044] When thermal runaway of the battery pack is detected, the cooling device is turned on to cool the battery pack.

[0045] Specifically, the multiple battery packs in the battery compartment of the present application are all provided with cooling devices; when the battery pack has thermal runaway, the cooling device will automatically identify the current thermal runaway state of the battery pack and automatically cool down the battery pack; the cooling agent in the cooling device is sprayed out through the provided nozzle, and the agent is immersed in the entire battery pack to cool down the battery pack. It should be noted that the present application does not limit the specific type of cooling agent in the cooling device; illustratively, the cooling agent is perfluorohexanone; in actual applications, perfluorohexanone has efficient fire extinguishing ability and cooling effect, and perfluorohexanone is highly safe for the environment and personnel, so it can be used in various scenarios. In this example, by providing a cooling device in the battery pack, thermal runaway can be suppressed when thermal runaway occurs in the battery pack, further improving the protection effect of the battery compartment.

[0046] Specifically, it is necessary to accurately determine the state of thermal runaway to accurately determine whether the battery pack has thermal runaway; accordingly, as an example, a thermistor is also provided in the battery pack to obtain the thermal runaway state of the battery pack in the battery compartment, including:

[0047] Monitor the resistance change of the thermistor wire;

[0048] When the resistance change of the thermistor line exceeds a first preset value, it is determined that thermal runaway occurs in the battery pack.

[0049] The battery pack of the present application is provided with a thermistor for sensing the ambient temperature inside the battery pack. When the thermistor senses a change in the temperature of the battery pack, the resistance value of the thermistor will change accordingly. When the battery pack experiences thermal runaway, the change in the resistance value of the thermistor will exceed a preset value, and this change can be detected by the connected control circuit. When the battery pack is in a thermal runaway state, the aforementioned cooling device is turned on to cool the battery pack. In practical applications, a thermistor is a wire that can deform or melt within a certain temperature range, and its working principle is based on the change in the resistance of the material with temperature. When the detected change in the resistance value of the thermistor exceeds a preset range, it is determined that the battery pack has experienced a thermal runaway state, which improves the accuracy of the judgment result of the thermal runaway state of the battery pack, and subsequently issues an early warning based on the accurate judgment result, which improves the accuracy of the early warning and further enhances the protection effect.

[0050] Furthermore, different thermal runaway states of battery packs and battery compartment temperatures correspond to different warning levels; accordingly, as an example, Figure 2 A schematic flow chart of an emergency treatment method for a battery compartment is exemplarily shown; based on any example, step 102 specifically includes:

[0051] Step 201: If the battery pack is in a thermal runaway state and the current temperature of the battery compartment exceeds a second preset value, determine that the current warning level is a level 3 warning;

[0052] Step 202: If the battery pack has thermal runaway or the current temperature of the battery compartment exceeds a second preset value, determine that the current warning level is a level 2 warning.

[0053] Specifically, when the thermal runaway state of the battery pack is obtained, when the battery pack is detected to have thermal runaway, and at the same time, the temperature detector detects that the temperature in the battery compartment exceeds the second preset value, then the warning level at this time is determined to be a level three warning; if the battery pack is detected to have thermal runaway, or if the temperature of the battery compartment is detected to have exceeded the second preset value, then the warning level at this time is determined to be a level two warning, and a level two warning is when only one of these two situations occurs. If neither condition is met, no warning of the corresponding level is issued, and it is determined to be another situation; different warning levels lead to different emergency protection measures. In this example, the accuracy of the warning level determination is improved by determining the corresponding warning level according to different thermal runaway states of the battery pack and different battery compartment temperatures.

[0054] Further, according to the corresponding warning level, corresponding emergency protection measures are implemented; accordingly, as an example, Figure 3 A schematic flow chart of an emergency handling method for a battery compartment is exemplarily shown. Based on any example, the battery compartment further includes a fire extinguishing system, and step 103 specifically includes:

[0055] Step 301: If the warning level is level 3, the fire extinguishing system is activated to perform fire extinguishing processing;

[0056] Step 302: If the warning level is level 2, the power supply of the battery compartment is cut off.

[0057] Exemplarily, the battery compartment of the present application is provided with a fire extinguishing system; if the current warning level is a level three warning, the fire extinguishing system is activated to extinguish the fire in the battery compartment; in actual application, if the current warning level is a level three warning, the fire extinguishing system will be delayed for a certain period of time to start; the delayed start of the fire extinguishing system can ensure the safe evacuation of personnel; it can also reduce the losses caused by false alarms. False alarms of the fire extinguishing system may cause unnecessary panic and waste of resources. A certain delay time allows the fire duty personnel to check whether the system has false alarms, thereby avoiding unnecessary fire extinguishing operations. If it is confirmed to be a false alarm, the fire extinguishing procedure can be terminated immediately to reduce unnecessary losses and equipment damage; in addition, the accuracy and reliability of the system are improved. The accuracy of the fire extinguishing system is crucial to its effectiveness; the delay mechanism allows the system to make a final confirmation before officially starting, improve the accuracy and reliability of the system, and ensure that the maximum fire extinguishing effect can be achieved when it is really needed.

[0058] If the current warning level is level 2, the power supply of the battery compartment is cut off to avoid fire and explosion. In this example, when the warning level is determined to be level 2, the power supply of the battery compartment is cut off; illustratively, the battery management system in the battery compartment will trip the compartment-level circuit breaker and the cluster-level relay to ensure that the power supply of the battery compartment is disconnected; at the same time, the sound and light alarm of the protection area will be activated. Among them, the sound and light alarm can simultaneously emit a high-decibel alarm sound and a flashing light signal, and is an important part of the safety protection system; by real-time monitoring of abnormal conditions in the protection area and immediately issuing an alarm when a danger is detected, the sound and light alarm can strengthen safety protection and reduce the probability of accidents; at the same time, it is linked with other safety equipment to form a complete security system and improve the safety protection capabilities of the enterprise. In actual applications, the battery management system is responsible for monitoring, managing and protecting the battery pack; the compartment-level circuit breaker and the cluster-level relay are key safety components in the battery system; the compartment-level circuit breaker is usually used to control the power on and off of the entire battery compartment, while the cluster-level relay is used to control the power on and off of the battery cluster (i.e., a group of battery cells). When the battery management system detects an abnormality or failure in the battery system, in order to protect the battery pack and the entire battery system from damage, it will take measures such as tripping the compartment-level circuit breaker and cluster-level relay to protect the battery pack and the entire battery system from damage.

[0059] In this example, corresponding emergency treatment measures are executed according to the warning level, which can accurately and effectively implement emergency treatment and protection for the battery compartment.

[0060] Furthermore, after determining the battery compartment warning level according to the thermal runaway state of the battery and the temperature of the battery compartment, the warning level of the battery compartment is also corrected according to other parameters of the battery compartment; accordingly, as an example, after determining the current warning level according to the current temperature and thermal runaway state of the battery compartment, it also includes:

[0061] According to the solid particle concentration value and combustible gas concentration value of the battery compartment, the current warning level is corrected; the correction includes:

[0062] If the current warning level is level 3, and at least one of the solid particle concentration value and the combustible gas concentration value reaches the threshold, the current warning level remains at level 3;

[0063] If the current warning level is level 2, and at least one of the solid particle concentration value and the combustible gas concentration value reaches the threshold, the current warning level is adjusted to level 1;

[0064] If the current warning level is neither level 3 nor level 2, and the combustible gas concentration value exceeds the threshold, the current warning level will be adjusted to level 1.

[0065] Specifically, the current warning level is corrected according to the detected solid particle concentration value and combustible gas concentration value in the battery compartment; if the current warning level is level 3 warning, at this time, any one of the solid particle concentration value or the combustible gas concentration value in the battery compartment exceeds its corresponding threshold value; or the solid particle concentration value and the combustible gas concentration value exceed their corresponding threshold values ​​at the same time; then the current warning level is maintained as level 3 warning. If the current warning level is level 2 warning, at this time, when at least one of the solid particle concentration value and the combustible gas concentration value reaches its corresponding threshold value, or both reach their corresponding threshold values ​​at the same time, the current warning level is adjusted to level 3 warning. If the current level is neither level 3 warning nor level 2 warning, and the combustible gas concentration value exceeds the threshold value at this time, the current warning level is adjusted to level 1. In practical applications, solid particles include dust, metal particles, impurities, etc.; in the battery compartment, if the concentration of solid particles is too high, once encountering a fire source or high temperature conditions, it may cause a fire. The concentration of combustible gas is an important safety indicator. When the concentration of combustible gas exceeds a certain limit, it may cause a fire or explosion. Therefore, effective measures should be taken to suppress the concentration of combustible gas in the battery compartment to prevent combustion or explosion of the battery compartment. In this example, the accuracy of the warning level division is improved by further correcting the warning level of the battery compartment according to the solid particle concentration value and the combustible gas concentration value in the battery compartment.

[0066] Furthermore, it is necessary to accurately detect the concentration of solid particles and the concentration of combustible gas in the battery compartment; accordingly, as an example, the battery compartment is provided with a smoke detector and a combustible gas detector;

[0067] Smoke detectors are used to detect the concentration of solid particles in the battery compartment;

[0068] The combustible gas detector is used to detect the combustible gas concentration in the battery compartment.

[0069] Specifically, a smoke detector and a combustible gas concentration detector are installed in the battery compartment; the smoke detector is used to detect the concentration of solid particles in the battery compartment; the combustible gas concentration detector is used to detect the concentration of combustible gas in the battery compartment. In practical applications, a smoke detector is a device used to detect smoke or particles produced by combustion in the air, and plays an important role in fire warning and safety protection; it can detect smoke in time and trigger an alarm to take corresponding measures, effectively reducing the occurrence of fire accidents and protecting the safety of people and property. A combustible gas concentration detector is a device used to detect the concentration of a single or multiple combustible gases. The combustible gas concentration detector can monitor the concentration of combustible gases in the environment in real time. When the concentration reaches the preset alarm threshold, it will send out an audible and visual alarm signal to remind the operator to take timely measures to prevent the occurrence of fire or explosion accidents.

[0070] In this example, smoke detectors and combustible gas concentration detectors are set to detect the solid particle concentration and combustible gas concentration inside the battery compartment. The solid particle concentration values ​​and combustible gas concentration values ​​in the battery compartment can be accurately detected, and the division of warning levels can be further corrected according to the accurate concentration values, thereby further improving the accuracy of the division of warning levels.

[0071] Furthermore, the battery compartment is provided with ventilation equipment; step 103 also includes:

[0072] If the warning level is level one, turn on the ventilation equipment.

[0073] Specifically, ventilation equipment is also provided in the battery compartment. If the current warning level is the third-level warning, it indicates that the concentration of combustible gas in the battery compartment exceeds the standard. At this time, the ventilation equipment in the battery compartment is turned on for ventilation. When the concentration of combustible gas in the battery compartment exceeds the threshold, it may cause a fire or explosion once it encounters an open flame or high temperature. Therefore, the ventilation equipment needs to be turned on to quickly discharge the combustible gas in the compartment, thereby reducing its concentration and reducing the risk of fire or explosion. In this example, when the warning level is the first-level warning, the ventilation equipment is turned on, which reduces the risk of causing fire and explosion, and further improves the emergency treatment and protection effect of the battery compartment.

[0074] As an example, Figure 4 This is a schematic diagram of the structure of a battery compartment of an example of this application; Figure 4 As shown, the battery compartment includes a battery pack. In actual applications, there may be multiple battery packs. Figure 4This is just an example case; the battery compartment also includes a temperature detector, a smoke detector, and a combustible gas detector; a cooling module is set in the battery pack; when the battery pack has thermal runaway, the cooling module is turned on to release cooling agents to cool the battery pack; at the same time, based on the temperature of the battery compartment detected by the temperature detector in the battery compartment, the concentration of solid particles detected by the smoke detector in the battery compartment, and the concentration of combustible gas detected by the combustible gas detector in the battery compartment, combined with the thermal runaway state of the battery pack, the corresponding warning level is jointly determined, and specific emergency protection measures for the battery compartment are performed according to different warning levels.

[0075] As another example, Figure 5 Schematic diagram of the emergency handling process of the battery compartment applied for; Figure 5 As shown, the thermal runaway state of the detected battery pack, the temperature value of the battery compartment detected by the temperature detector, the solid particle concentration value detected by the smoke detector, and the combustible gas concentration value are transmitted to the control unit, and the control unit divides the warning level according to the received parameters;

[0076] When a thermal runaway state is detected, the temperature value of the battery compartment detected by the temperature detector exceeds the threshold, the solid particle concentration value of the battery compartment detected by the smoke detector exceeds the threshold, and the combustible gas concentration of the battery compartment detected by the combustible gas detector exceeds the threshold. If at least two of these conditions exist at the same time, the current warning level is level three. For level three warnings, the fire extinguishing system is activated to extinguish the fire.

[0077] When thermal runaway of the battery pack is detected, or the temperature value of the battery compartment detected by the temperature detector exceeds the threshold, or the solid particle concentration value of the battery compartment detected by the smoke detector exceeds the threshold, the current warning level is determined to be a level 2 warning; for the level 2 warning, the battery management system will trip the compartment-level circuit breaker and cluster-level relay, and start the protection area sound and light alarm processing.

[0078] When only the combustible gas concentration in the battery compartment detected by the combustible gas detector exceeds the threshold, the warning level at this time is determined to be a level one warning; for the level one warning, the ventilation equipment is turned on for ventilation.

[0079] The emergency handling method for the battery compartment provided in this embodiment obtains the thermal runaway state of the battery pack in the battery compartment and the current temperature in the battery compartment; the two are combined to determine the current warning level of the battery compartment; for different warning levels, emergency protection measures under the corresponding warning level are taken. The solution of this application combines the detection of whether the battery pack is in a thermal runaway state with the current temperature in the battery compartment to determine the warning level, which improves the accuracy of the warning level judgment; at the same time, effective protection measures can be taken according to the accurate warning level, which improves the protection effect of the battery compartment, further improves safety, and effectively prevents the occurrence of fire accidents.

[0080] Embodiment 2

[0081] Figure 6 The schematic diagram of the structure of an emergency treatment device for a battery compartment is shown as an example; Figure 6 As shown, the device comprises:

[0082] An acquisition module 21 is used to acquire a thermal runaway state of a battery pack in a battery compartment, where the thermal runaway state indicates whether the battery pack has thermal runaway; and to acquire a current temperature of the battery compartment;

[0083] A determination module 22, used to determine a current warning level according to a current temperature and a thermal runaway state of the battery compartment;

[0084] The processing module 23 is used to execute corresponding emergency protection measures according to the current warning level.

[0085] Specifically, this application is used to perform emergency treatment and protection on the battery compartment; first, the thermal runaway state of the battery pack is obtained. The thermal runaway state obtained in this example indicates whether the battery pack has thermal runaway; in actual applications, thermal runaway of the battery pack refers to the phenomenon that the battery pack generates a large amount of heat due to the runaway of the internal electrochemical reaction without the action of an external heat source, which in turn causes the battery temperature to rise sharply; this phenomenon is often accompanied by the chain start of complex chemical reactions inside the battery, such as the oxidation decomposition of the electrolyte, the rupture of the solid electrolyte interface membrane, the thermal decomposition of the positive electrode material, etc., which may eventually cause serious consequences such as combustion and explosion. At the same time, the current temperature value of the battery compartment is obtained. The current temperature of the battery compartment refers to the temperature value at the location outside the battery pack and inside the battery compartment; according to the obtained thermal runaway state of the battery pack and the current temperature value of the battery compartment, the current warning level is determined; the corresponding emergency protection treatment measures are executed according to the determined warning level. Different thermal runaway states and different battery compartment temperatures correspond to different warning levels; therefore, different warning levels correspond to different emergency protection measures. Emergency protection measures for battery compartments mainly refer to a series of preventive, response and disposal measures taken to ensure personnel safety and reduce property losses when the battery compartment faces potential safety risks or emergencies. In this example, the current warning level is determined based on the thermal runaway state of the battery pack in the battery compartment and the current temperature of the battery compartment. Corresponding emergency protection measures are formulated according to different warning levels, which improves the accuracy of warning level determination and further improves the effectiveness of the emergency protection measures implemented.

[0086] Furthermore, a temperature sensor is provided in the battery compartment; obtaining the current temperature of the battery compartment includes:

[0087] The temperature currently collected by the temperature sensor is obtained as the current temperature of the battery compartment.

[0088] The battery compartment of the present application includes a temperature detector, which is used to detect the temperature of the entire battery compartment; when the current temperature of the battery compartment needs to be obtained, the temperature collected by the temperature detector can be obtained as the current temperature of the battery compartment. In practical applications, a temperature detector, also known as a point-type temperature-sensitive fire detector, is a fire detector that is mainly used to respond to temperature changes around a certain point or a certain line in the warning range; the working principle of the temperature detector is based on the sensitivity of thermistors to temperature changes. When a fire occurs, the combustion of substances releases a large amount of heat, causing the surrounding temperature to rise sharply. The thermistor in the detector can sense this temperature change and convert it into an electrical signal; when the temperature reaches or exceeds the set threshold, the detector will trigger an alarm and transmit the signal to the relevant fire alarm system. In this example, the temperature of the battery compartment is detected using a temperature detector, which improves the accuracy of the battery compartment temperature detection.

[0089] Furthermore, when the battery pack is in a state of thermal runaway, the battery pack needs to be cooled; accordingly, as an example, a cooling device is provided in the battery pack; when thermal runaway of the battery pack is detected, the cooling device is turned on to cool the battery pack.

[0090] Specifically, the multiple battery packs in the battery compartment of the present application are all provided with cooling devices; when the battery pack has thermal runaway, the cooling device will automatically identify the current thermal runaway state of the battery pack and automatically cool down the battery pack; the cooling agent in the cooling device is sprayed out through the provided nozzle, and the agent is immersed in the entire battery pack to cool down the battery pack. It should be noted that the present application does not limit the specific type of cooling agent in the cooling device; illustratively, the cooling agent is perfluorohexanone; in actual applications, perfluorohexanone has efficient fire extinguishing ability and cooling effect, and perfluorohexanone is highly safe for the environment and personnel, so it can be used in various scenarios. In this example, by providing a cooling device in the battery pack, thermal runaway can be suppressed when thermal runaway occurs in the battery pack, further improving the protection effect of the battery compartment.

[0091] Specifically, it is necessary to accurately determine the state of thermal runaway to accurately determine whether the battery pack has thermal runaway; accordingly, as an example, a thermistor is also provided in the battery pack to obtain the thermal runaway state of the battery pack in the battery compartment, including:

[0092] Monitor the resistance change of the thermistor wire;

[0093] When the resistance change of the thermistor line exceeds a first preset value, it is determined that thermal runaway occurs in the battery pack.

[0094] The battery pack of the present application is provided with a thermistor for sensing the ambient temperature inside the battery pack. When the thermistor senses a change in the temperature of the battery pack, the resistance value of the thermistor will change accordingly. When the battery pack experiences thermal runaway, the change in the resistance value of the thermistor will exceed a preset value, and this change can be detected by the connected control circuit. When the battery pack is in a thermal runaway state, the aforementioned cooling device is turned on to cool the battery pack. In practical applications, a thermistor is a wire that can deform or melt within a certain temperature range, and its working principle is based on the change in the resistance of the material with temperature. When the detected change in the resistance value of the thermistor exceeds a preset range, it is determined that the battery pack has experienced a thermal runaway state, which improves the accuracy of the judgment result of the thermal runaway state of the battery pack, and subsequently issues an early warning based on the accurate judgment result, which improves the accuracy of the early warning and further enhances the protection effect.

[0095] Furthermore, different thermal runaway states of different battery packs and temperatures of the battery compartments correspond to different warning levels; accordingly, as an example, the determination module 21 is used to:

[0096] If the battery pack is in thermal runaway state and the current temperature of the battery compartment exceeds the second preset value, the current warning level is determined to be a level 3 warning;

[0097] If thermal runaway occurs in the battery pack or the current temperature of the battery compartment exceeds the second preset value, the current warning level is determined to be a level 2 warning.

[0098] Specifically, when the thermal runaway state of the battery pack is obtained, when the battery pack is detected to have thermal runaway, and at the same time, the temperature detector detects that the temperature in the battery compartment exceeds the second preset value, then the warning level at this time is determined to be a level three warning; if the battery pack is detected to have thermal runaway, or if the temperature of the battery compartment is detected to have exceeded the second preset value, then the warning level at this time is determined to be a level two warning, and a level two warning is when only one of these two situations occurs. If neither condition is met, no warning of the corresponding level is issued, and it is determined to be another situation; different warning levels lead to different emergency protection measures. In this example, the accuracy of the warning level determination is improved by determining the corresponding warning level according to different thermal runaway states of the battery pack and different battery compartment temperatures.

[0099] Further, according to the corresponding warning level, corresponding emergency protection measures are executed; accordingly, as an example, the processing module 23 is used to:

[0100] If the warning level is level three, the fire extinguishing system will be activated to perform fire extinguishing treatment;

[0101] If the warning level is level 2, the power supply to the battery compartment is cut off.

[0102] Exemplarily, the battery compartment of the present application is provided with a fire extinguishing system; if the current warning level is a level three warning, the fire extinguishing system is activated to extinguish the fire in the battery compartment; in actual application, if the current warning level is a level three warning, the fire extinguishing system will be delayed for a certain period of time to start; the delayed start of the fire extinguishing system can ensure the safe evacuation of personnel; it can also reduce the losses caused by false alarms. False alarms of the fire extinguishing system may cause unnecessary panic and waste of resources. A certain delay time allows the fire duty personnel to check whether the system has false alarms, thereby avoiding unnecessary fire extinguishing operations. If it is confirmed to be a false alarm, the fire extinguishing procedure can be terminated immediately to reduce unnecessary losses and equipment damage; in addition, the accuracy and reliability of the system are improved. The accuracy of the fire extinguishing system is crucial to its effectiveness; the delay mechanism allows the system to make a final confirmation before officially starting, improve the accuracy and reliability of the system, and ensure that the maximum fire extinguishing effect can be achieved when it is really needed.

[0103] If the current warning level is level 2, the power supply of the battery compartment is cut off to avoid fire and explosion. In this example, when the warning level is determined to be level 2, the power supply of the battery compartment is cut off; illustratively, the battery management system in the battery compartment will trip the compartment-level circuit breaker and the cluster-level relay to ensure that the power supply of the battery compartment is disconnected; at the same time, the sound and light alarm of the protection area will be activated. Among them, the sound and light alarm can simultaneously emit a high-decibel alarm sound and a flashing light signal, and is an important part of the safety protection system; by real-time monitoring of abnormal conditions in the protection area and immediately issuing an alarm when a danger is detected, the sound and light alarm can strengthen safety protection and reduce the probability of accidents; at the same time, it is linked with other safety equipment to form a complete security system and improve the safety protection capabilities of the enterprise. In actual applications, the battery management system is responsible for monitoring, managing and protecting the battery pack; the compartment-level circuit breaker and the cluster-level relay are key safety components in the battery system; the compartment-level circuit breaker is usually used to control the power on and off of the entire battery compartment, while the cluster-level relay is used to control the power on and off of the battery cluster (i.e., a group of battery cells). When the battery management system detects an abnormality or failure in the battery system, in order to protect the battery pack and the entire battery system from damage, it will take measures such as tripping the compartment-level circuit breaker and cluster-level relay to protect the battery pack and the entire battery system from damage.

[0104] In this example, corresponding emergency treatment measures are executed according to the warning level, which can accurately and effectively implement emergency treatment and protection for the battery compartment.

[0105] Further, after determining the battery compartment warning level according to the thermal runaway state of the battery and the temperature of the battery compartment, the warning level of the battery compartment is also corrected according to other parameters of the battery compartment; accordingly, as an example, the device of the present application also includes a correction module 24, which is used to: after determining the current warning level according to the current temperature and thermal runaway state of the battery compartment, the correction module 24 is used to:

[0106] According to the solid particle concentration value and combustible gas concentration value of the battery compartment, the current warning level is corrected; the correction includes:

[0107] If the current warning level is level 3, and at least one of the solid particle concentration value and the combustible gas concentration value reaches the threshold, the current warning level remains at level 3;

[0108] If the current warning level is level 2, and at least one of the solid particle concentration value and the combustible gas concentration value reaches the threshold, the current warning level is adjusted to level 3;

[0109] If the current warning level is neither level 3 nor level 2, and the combustible gas concentration value exceeds the threshold, the current warning level will be adjusted to level 1.

[0110] Specifically, the current warning level is corrected according to the detected solid particle concentration value and combustible gas concentration value in the battery compartment; if the current warning level is level 3 warning, at this time, any one of the solid particle concentration value or the combustible gas concentration value in the battery compartment exceeds its corresponding threshold value; or the solid particle concentration value and the combustible gas concentration value exceed their corresponding threshold values ​​at the same time; then the current warning level is maintained as level 3 warning. If the current warning level is level 2 warning, at this time, when at least one of the solid particle concentration value and the combustible gas concentration value reaches its corresponding threshold value, or both reach their corresponding threshold values ​​at the same time, the current warning level is adjusted to level 3 warning. If the current level is neither level 3 warning nor level 2 warning, and the combustible gas concentration value exceeds the threshold value at this time, the current warning level is adjusted to level 1. In practical applications, solid particles include dust, metal particles, impurities, etc.; in the battery compartment, if the concentration of solid particles is too high, once encountering a fire source or high temperature conditions, it may cause a fire. The concentration of combustible gas is an important safety indicator. When the concentration of combustible gas exceeds a certain limit, it may cause a fire or explosion. Therefore, effective measures should be taken to suppress the concentration of combustible gas in the battery compartment to prevent combustion or explosion of the battery compartment. In this example, the accuracy of the warning level division is improved by further correcting the warning level of the battery compartment according to the solid particle concentration value and the combustible gas concentration value in the battery compartment.

[0111] Furthermore, it is necessary to accurately detect the concentration of solid particles and the concentration of combustible gas in the battery compartment; accordingly, as an example, the battery compartment is provided with a smoke detector and a combustible gas detector;

[0112] Smoke detectors are used to detect the concentration of solid particles in the battery compartment;

[0113] The combustible gas detector is used to detect the combustible gas concentration in the battery compartment.

[0114] Specifically, a smoke detector and a combustible gas concentration detector are installed in the battery compartment; the smoke detector is used to detect the concentration of solid particles in the battery compartment; the combustible gas concentration detector is used to detect the concentration of combustible gas in the battery compartment. In practical applications, a smoke detector is a device used to detect smoke or particles produced by combustion in the air, and plays an important role in fire warning and safety protection; it can detect smoke in time and trigger an alarm to take corresponding measures, effectively reducing the occurrence of fire accidents and protecting the safety of people and property. A combustible gas concentration detector is a device used to detect the concentration of a single or multiple combustible gases. The combustible gas concentration detector can monitor the concentration of combustible gases in the environment in real time. When the concentration reaches the preset alarm threshold, it will send out an audible and visual alarm signal to remind the operator to take timely measures to prevent the occurrence of fire or explosion accidents.

[0115] In this example, smoke detectors and combustible gas concentration detectors are set to detect the solid particle concentration and combustible gas concentration inside the battery compartment. The solid particle concentration values ​​and combustible gas concentration values ​​in the battery compartment can be accurately detected, and the division of warning levels can be further corrected according to the accurate concentration values, thereby further improving the accuracy of the division of warning levels.

[0116] Furthermore, the battery compartment is provided with ventilation equipment; the processing module 23 is also used for:

[0117] If the warning level is level one, turn on the ventilation equipment.

[0118] Specifically, ventilation equipment is also provided in the battery compartment. If the current warning level is the third-level warning, it indicates that the concentration of combustible gas in the battery compartment exceeds the standard. At this time, the ventilation equipment in the battery compartment is turned on for ventilation. When the concentration of combustible gas in the battery compartment exceeds the threshold, it may cause a fire or explosion once it encounters an open flame or high temperature. Therefore, the ventilation equipment needs to be turned on to quickly discharge the combustible gas in the compartment, thereby reducing its concentration and reducing the risk of fire or explosion. In this example, when the warning level is the first-level warning, the ventilation equipment is turned on, which reduces the risk of causing fire and explosion, and further improves the emergency treatment and protection effect of the battery compartment.

[0119] The emergency handling device for the battery compartment provided in this embodiment obtains the thermal runaway state of the battery pack in the battery compartment and the current temperature in the battery compartment; the two are combined to determine the current warning level of the battery compartment; for different warning levels, emergency protection measures under the corresponding warning level are taken. The solution of this application combines the detection of whether the battery pack is in a thermal runaway state with the current temperature in the battery compartment to determine the warning level, which improves the accuracy of the warning level judgment; at the same time, effective protection measures can be taken according to the accurate warning level, which improves the protection effect of the battery compartment, further improves safety, and effectively prevents the occurrence of fire accidents.
