[0047] As the global demand for clean energy rises, the energy storage industry has developed rapidly and its scale continues to expand. However, in recent years, energy storage safety accidents have become common. Energy storage firefighting technologies such as early detection, precise prevention and control, and fire extinguishing are constantly iterating to meet the industry's safety needs and ensure the safe and stable operation of energy storage cabins.

[0048] Figure 1A schematic diagram of a fire control method for an energy storage compartment provided in an embodiment of the present application, such as Figure 1 As shown, the present application is applied to an energy storage cabin, which includes multiple battery clusters, video surveillance equipment ④, a fire protection system and a ventilation system, wherein the fire protection system includes a fire detection device and a controller ⑤, the fire detection device includes a smoke detection unit ①, a combustible gas detection unit ② and a temperature detection unit ③, and the ventilation system includes air inlet louvers ⑥ and an exhaust fan ⑦.

[0049] Among them, fire detection devices such as smoke detection unit ①, combustible gas detection unit ② and temperature detection unit ③ are communicated with controller ⑤ to monitor the fire situation in the energy storage cabin; video monitoring equipment ④ is set in the energy storage cabin for real-time monitoring of the energy storage cabin; the ventilation system is used to adjust the temperature, discharge harmful gases generated by the operation of the equipment, and maintain the air quality.

[0050] Combined with the above scenarios, it can be seen that in the existing technology, monitoring through traditional detectors has the problem of limited monitoring range, and temperature detectors need to wait until the temperature rises significantly, smoke detectors need the smoke concentration to reach a certain threshold before responding, and combustible gas detectors need the combustible gas concentration to reach or exceed the set alarm threshold before responding. Traditional fire monitoring methods have the problem of not being accurate enough in identifying the characteristics of early fires.

[0051] The fire control method for energy storage cabins provided in the present application detects early characteristics of fire through video monitoring equipment and video recognition technology, monitors fire hazards in combination with fire detection devices, and takes effective fire extinguishing and prevention measures, thereby solving the problems of limited monitoring range of traditional detectors and inaccurate identification of early fire characteristics.

[0052] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0053] Figure 2 A schematic diagram of a fire control method for an energy storage compartment provided in an embodiment of the present application Figure 1 This embodiment is applied to an energy storage cabin, which includes: a plurality of Figure 1 The battery cluster, fire detection device and controller shown in the figure, the fire detection device includes: a video detection unit, a cabin level detection unit and a composite detection unit, the video detection unit, the cabin level detection unit and the composite detection unit are all connected to the controller, such as Figure 2 As shown, the method includes:

[0054] S201, the controller obtains first detection information sent by the video detection unit, second detection information sent by the cabin-level detection unit, and third detection information sent by the composite detection unit;

[0055] Among them, the detection information is used to indicate the environmental information inside the energy storage cabin; the video detection unit is arranged in the key monitoring area inside the energy storage cabin, and is used to perform all-round real-time monitoring of the entire energy storage cabin, and the first detection information is used to indicate the monitoring data; the cabin-level detection unit is used to indicate the traditional sensor, which is used to detect the safety parameters of the energy storage cabin, and the second detection information is used to indicate the safety parameters; the composite detection unit is a sensor inside the battery module, which is used to monitor the status parameters of the battery module in real time, and the third detection information is used to indicate the status parameters of the battery module.

[0056] The controller obtains the monitoring data sent by the video detection unit, the safety parameters sent by the cabin-level detection unit, and the status parameters of the battery module sent by the composite detection unit.

[0057] The video detection unit can be, for example, a high-definition camera, which can perform all-round real-time monitoring of the entire energy storage cabin. The monitoring data monitored by the high-definition camera can be identified and processed through video recognition technology. It can accurately detect and identify these signs in the very early stages of a fire, such as when a battery thermal runaway initially produces smoke, a tiny flame, or an electrical fault produces a weak arc.

[0058] The cabin-level detection unit may be, for example, a smoke sensor, a temperature sensor, a flame sensor, a combustible gas sensor, etc. The second detection information may be, for example, smoke, temperature, ultraviolet rays, combustible gas concentration, etc. In addition, the cabin-level detection unit may be a point-type detection unit or a line-type detection unit. The present application does not impose any restrictions on this. Exemplary: The cabin-level detection unit may include, for example, a temperature-sensitive fire detector, which may be a point-type temperature-sensitive fire detector, which sends second detection information to the controller after detecting that the ambient temperature exceeds a threshold value, and the second detection information may be, for example, an early warning signal at this time; the temperature-sensitive fire detector may also be a line-type temperature-sensitive fire detector, which continuously sends the detected ambient temperature to the controller, and sends an early warning signal to the controller when the detected ambient temperature exceeds a threshold value.

[0059] Fire hazards inside battery modules are often hidden. Problems such as short circuits, overcharging, and over-discharging may occur quietly inside the battery and are difficult to observe directly from the outside. For example, a micro short circuit between the poles inside the battery may gradually cause the temperature to rise, but in the early stages, there may be no obvious changes in the battery shell. These potential problems can be discovered in a timely manner through sensors inside the battery module.

[0060] S202. The controller determines the fire protection type and fire protection level of the energy storage compartment based on the first detection information, the second detection information, and the third detection information, and adopts a corresponding fire protection plan based on the fire protection type and the fire protection level.

[0061] Among them, the fire protection type is used to indicate the type of environmental information abnormality, and the fire protection level corresponds to the degree of environmental information abnormality.

[0062] The controller determines the fire protection type and fire protection level of the energy storage compartment based on the monitoring data sent by the video detection unit, the safety parameters sent by the cabin detection unit, and the status parameters of the battery module sent by the composite detection unit. The controller then starts the corresponding fire extinguishing program and fire extinguishing device based on the fire protection type and fire protection level. This realizes an integrated automated process from monitoring to early warning to disposal, greatly improving the response speed and fire extinguishing efficiency of the fire protection system and effectively preventing the spread of fire.

[0063] For example: when the controller obtains that the combustible gas concentration reaches a low fire threshold, the controller controls the ventilation equipment to open to prevent the accumulation of combustible gas and explosion; when the controller obtains that the combustible gas concentration reaches a high fire threshold, the controller controls the ventilation equipment to close to prevent the fire from spreading.

[0064] A fire control method for an energy storage cabin provided in an embodiment of the present application accurately detects and identifies early fire characteristics in a very early stage of the fire by acquiring first detection information sent by a video detection unit, thereby discovering fire hazards in advance and shortening the fire warning time; the fire type and fire level of the energy storage cabin are determined according to the first detection information, the second detection information and the third detection information, and a corresponding fire protection plan is adopted based on the fire type and fire level, thereby improving the response speed and fire extinguishing efficiency of the fire protection system, effectively preventing the spread of fire, and realizing an integrated automated process from monitoring to warning to disposal.

[0065] Figure 3 A schematic diagram of a fire control method for an energy storage compartment provided in an embodiment of the present application Figure 2 In this embodiment, the energy storage cabin includes a ventilation system, an alarm device, a battery management system, and a fire extinguishing device; the ventilation system, the alarm device, and the battery management system are all connected to the controller, and the cabin-level detection unit includes a combustible gas detection unit, a smoke detection unit, and a temperature detection unit. The first detection information includes a combustible gas warning signal, a smoke warning signal, and a temperature warning signal, wherein the combustible gas warning signal includes a combustible gas low concentration warning signal and a combustible gas high concentration warning signal. In this embodiment, Figure 2 Based on the embodiment, a fire control method for an energy storage cabin is described in detail, such as Figure 3 As shown, the method includes:

[0066] S301, obtaining a combustible gas low concentration warning signal sent by a combustible gas detection unit;

[0067] S302, determining that the fire protection type is the first fire protection type and the fire protection level of the energy storage compartment is the first level fire protection;

[0068] The main function of the low concentration warning signal of flammable gas is safety prevention. In the early stage of flammable gas leakage, the concentration may still be relatively low, but it is a dangerous signal. Early warning can prevent the flammable gas from reaching a dangerous concentration without knowing it. Therefore, the fire protection type is determined to be the first fire protection type, and the low concentration warning signal of flammable gas is the first warning, and its corresponding fire protection level is the first fire protection level.

[0069] S303, obtaining a smoke warning signal sent by the video detection unit / a smoke warning signal sent by the smoke detection unit / a temperature warning signal sent by the temperature detection unit / a battery cluster low-level warning signal sent by the composite detection unit / manual warning information;

[0070] S304, determining that the fire protection type is the second fire protection type, and the fire protection level of the energy storage compartment is the first fire protection level;

[0071] When any of the following conditions are met:

[0072] 1) The video detection unit sends a smoke warning signal;

[0073] 2) Smoke warning signal sent by the smoke detection unit;

[0074] 3) Temperature warning signal sent by the temperature detection unit;

[0075] 4) Low-level warning signal of battery cluster sent by the composite detection unit;

[0076] 5) Manual warning information.

[0077] This means that the situation has not been completely out of control, and serious problems such as battery thermal runaway have not occurred, so it can be preliminarily judged that the fire is of low severity. The fire type is determined to be the second fire type, corresponding to the first-level warning, and the corresponding fire level is the first-level fire level.

[0078] For example, when there is only a temperature warning, the temperature may only rise locally, and the heat has not yet been transferred in large quantities throughout the energy storage compartment. Unlike the sharp rise in temperature of the entire energy storage compartment caused by open flame combustion, the temperature change range at this time may be relatively small. For example, the temperature may only rise in a corner or near a row of battery modules, while the temperature in other areas is still within the normal range.

[0079] S305, obtaining a combustible gas high concentration warning signal sent by the combustible gas detection unit and a smoke warning signal sent by the smoke detection unit or a temperature warning signal sent by the temperature detection unit / a smoke warning signal sent by the smoke detection unit and a temperature warning signal sent by the temperature detection unit / a battery cluster high level warning signal sent by the composite detection unit / a fire alarm signal sent by the video detection unit;

[0080] S306, determining that the fire protection type is the third fire protection type, and the fire protection level of the energy storage compartment is the second level fire protection;

[0081] When any of the following conditions are met:

[0082] 1) Combustible gas high concentration warning signal and smoke warning signal;

[0083] 2) Combustible gas high concentration warning signal and temperature warning signal;

[0084] 3) Smoke warning signal and temperature warning signal;

[0085] 4) High-level warning signal of battery cluster;

[0086] 5) Fire alarm signal.

[0087] This indicates that there may be serious problems such as battery thermal runaway, so the preliminary judgment is that the fire is of high severity. The fire type is determined to be the third fire type, corresponding to the second-level warning, and the corresponding fire level is the second-level fire.

[0088] For example: When a high-concentration warning signal of combustible gas and a temperature warning signal are obtained, ideal conditions for combustion are formed. High-concentration combustible gas provides fuel, and high temperature provides the energy required to initiate and maintain combustion. Once combustion begins, the fire will spread rapidly due to the abundant combustible gas and high temperature.

[0089] S307, according to the preset program corresponding to the fire type and fire level, start the alarm device to alarm and control the ventilation system to turn on / off;

[0090] 1) When the fire type is the first fire type and the fire level is level one: control the ventilation system to start and send a level one warning signal to the battery management system.

[0091] 2) When the fire type is the second fire type and the fire level is the first fire level: send a first-level warning signal to the battery management system.

[0092] 3) When the fire type is the third fire type and the fire level is the second fire level: control the ventilation system to shut down and send a second-level warning signal to the battery management system.

[0093] The warning device may be, for example, an audible or visual alarm.

[0094] S308, controlling the battery management system to execute a fire emergency response linkage action;

[0095] Among them, the fire emergency response linkage actions include shutting down the air-cooled air conditioner, tripping the compartment-level circuit breakers and cluster-level relays.

[0096] After the battery management system receives the first-level warning signal, it shuts down the air-cooling air conditioner to effectively prevent the fire from spreading and avoid the risk of combustion. It also trips the compartment-level circuit breaker and cluster-level relay to avoid the expansion of the fault range.

[0097] After the battery management system receives the second-level warning signal, it turns off the air-cooled air conditioner, the compartment-level circuit breaker and the cluster-level relay, and cuts off the AC power in the distribution box to avoid electric sparks that may be generated by continuing to power on.

[0098] S309, when the first detection information / the second detection information is obtained, the cabin-level pipeline solenoid valve is opened, and the fire extinguishing device of the corresponding area is started;

[0099] When the first detection information sent by the video detection unit / the second detection information sent by the cabin detection unit is obtained, it indicates that the fire may spread to the energy storage cabin. The cabin pipeline solenoid valve is opened and the fire extinguishing device in the corresponding area is started to allow the fire extinguishing medium (such as fire extinguishing agent or fire extinguishing gas) to quickly fill the entire energy storage cabin, effectively covering a large area of ​​the burning area.

[0100] S310: When the third detection information is obtained, the cluster-level control valve corresponding to the third detection information is opened, and the fire extinguishing device of the corresponding area is started.

[0101] After obtaining the third detection information sent by the composite detection unit, it indicates that a small-scale battery cluster may have a fault. The cluster-level control valve is opened to accurately deliver the fire extinguishing medium to a specific battery cluster.

[0102] For example, Figure 4 A control logic diagram of a fire control system provided for an embodiment of the present application. The energy storage cabin is equipped with video surveillance equipment, composite detectors, and cabin-level detectors (including smoke detectors, combustible gas composite detectors, and temperature detectors) to monitor the energy storage cabin for fires. When an abnormality is detected, an abnormal signal is sent to the fire control host. The fire control pays attention to executing the intelligent linkage control between the sound and light alarm, ventilation, and fire extinguishing systems according to the preset logic. During the normal monitoring process, if there are problems such as equipment damage or equipment falling, they will be displayed through the host to avoid the inability to execute the fire extinguishing process when an actual fire occurs. The staff can also manually control the alarm button for manual warning. When the staff discovers a fire, the fire extinguishing system can be started urgently.

[0103] The embodiment of the present application provides a fire control method for an energy storage cabin. By acquiring a high-concentration warning signal of combustible gas sent by a combustible gas detection unit, a smoke warning signal sent by a smoke detection unit, a temperature warning signal sent by a temperature detection unit, a high-level warning signal of a battery cluster sent by a composite detection unit, a fire alarm signal sent by a video detection unit, and a manual warning signal, the method can accurately detect and identify early fire characteristics in the very early stage of a fire, discover fire hazards in advance, and shorten the fire warning time. According to the acquired warning signal, the fire type and fire level of the energy storage cabin are determined, and fire extinguishing disposal work is performed according to the preset procedures corresponding to the fire type and fire level, thereby improving the response speed and fire extinguishing efficiency of the fire protection system, effectively preventing the spread of fire, and realizing an integrated automated process from monitoring to warning to disposal.

[0104] The present application provides an energy storage cabin, which includes: a plurality of battery clusters, a fire detection device, and a controller. The fire detection device includes: a video detection unit, a cabin-level detection unit, and a composite detection unit. The video detection unit, the cabin-level detection unit, and the composite detection unit are all connected to the controller. The energy storage cabin includes:
