[0002] Energy storage devices are devices that can store and release electrical energy. They are widely used in scenarios such as power peak shaving, frequency regulation, and backup power. However, energy storage devices can cause thermal runaway during abuse such as overcharging, over-discharging, overheating, and short circuits, which can easily lead to fires.

[0003] However, in the process of implementing the embodiments of this application, the inventors discovered that: currently, when a fire occurs in an energy storage device, the fire extinguishing device of the energy storage device is activated to spray fire extinguishing agent to extinguish the fire, which makes the fire control measures of the energy storage device a single trigger mechanism, lacking a graded response strategy, and unable to take differentiated intervention measures according to the development stage of the fire.

[0036] For controller 5 mentioned above, please refer to Figure 3 The controller 5 includes at least one processor 51 and a memory 52. ​​The at least one processor 51 is connected to a first monitoring component, several second monitoring components 32, an alarm component 42, a first valve 4112, a second valve 4122, a third valve 4322, a first explosion-proof valve 441, a second explosion-proof valve 442, and a fan 45. The memory 52 stores instructions executable by the at least one processor 51.

[0037] In some embodiments, the energy storage device 100 further includes a management server 8, which is connected to the processor 51 and the battery module 2 respectively.

[0038] Please see Figure 4 , Figure 4 This is a flowchart of a first embodiment of the fire control method for the energy storage device 100 of the present invention, the method comprising: Step S1: Receive the monitoring data detected by the disaster monitoring device 3.

[0039] It should be noted that the monitoring data is obtained by the first monitoring component and the second monitoring component.

[0040] Step S2: Determine whether there is monitoring data that meets the preset disaster conditions.

[0041] It should be noted that the processor 51 determines whether monitoring data meeting the preset disaster conditions exists by comparing the monitoring data with the preset disaster conditions. The preset disaster conditions include preset Level 1, preset Level 2, and preset Level 3 disaster conditions. Preset Level 1 disaster conditions include a carbon monoxide concentration ≥ 400 ppm for 5 seconds, a temperature ≥ 65℃ for 5 seconds, and an optical smoke concentration ≥ 0.3 dB / m³ for 5 seconds. Preset Level 2 disaster conditions include a temperature ≥ 65℃ and a carbon monoxide concentration ≥ 800 ppm for 5 seconds, a temperature ≥ 65℃ and an optical smoke concentration ≥ 0.6 dB / m³ for 5 seconds, and a carbon monoxide concentration ≥ 800 ppm and an optical smoke concentration ≥ 0.6 dB / m³ for 5 seconds. The pre-defined Level 3 disaster conditions include: a temperature ≥ 85℃ and an optical smoke concentration ≥ 0.6 dB / m², lasting for 5 seconds; a temperature ≥ 85℃ and a carbon monoxide concentration ≥ 800 ppm, lasting for 5 seconds; an optical smoke concentration ≥ 0.6 dB / m², lasting for 5 seconds and a temperature rise ≥ 0.5℃ / s; and a carbon monoxide concentration ≥ 800 ppm, lasting for 5 seconds and a temperature rise ≥ 0.5℃ / s.

[0042] Furthermore, when the processor 51 compares and judges the monitoring data with the preset disaster conditions, it first judges whether the monitoring data meets the preset level three disaster conditions. If the monitoring data does not meet the preset level three disaster conditions, it judges whether the monitoring data meets the preset level two disaster conditions. If the monitoring data does not meet the preset level two disaster conditions, it judges whether the monitoring data meets the preset level one disaster conditions.

[0043] Step S3: If it exists, determine the disaster level of energy storage device 100 based on the monitoring data.

[0044] It should be noted that the disaster level includes Level 1, Level 2, and Level 3 disasters, and the fire extinguishing device 4 executes different response strategies according to different disaster levels. When the monitoring data meets the preset Level 1 disaster conditions, that is, when the monitoring data shows a carbon monoxide concentration ≥ 400 ppm for a duration of 5 seconds, or when the monitoring data shows a temperature ≥ 65℃ for a duration of 5 seconds, or when the monitoring data shows a smoke optical concentration ≥ 0.3 dB / m³ for a duration of 5 seconds, the processor 51 determines that the disaster level of the energy storage device 100 is Level 1. When the monitoring data meets any one of the preset Level II disaster conditions, namely when the monitoring data meets the conditions of temperature ≥ 65℃ and carbon monoxide concentration ≥ 800ppm for a duration of 5 seconds, or when the monitoring data meets the conditions of temperature ≥ 65℃ and smoke optical concentration ≥ 0.6db / m for a duration of 5 seconds, or when the monitoring data meets the conditions of carbon monoxide concentration ≥ 800ppm and smoke optical concentration ≥ 0.6db / m for a duration of 5 seconds, the processor 51 determines that the disaster level of the energy storage device 100 is Level II disaster. When the monitoring data meets any one of the preset Level 3 disaster conditions, namely, when the monitoring data meets the conditions of temperature ≥ 85℃ and optical smoke concentration ≥ 0.6dB / m² for a duration of 5 seconds, or when the monitoring data meets the conditions of temperature ≥ 85℃ and carbon monoxide concentration ≥ 800ppm for a duration of 5 seconds, or when the monitoring data meets the conditions of optical smoke concentration ≥ 0.6dB / m² for a duration of 5 seconds and temperature rise ≥ 0.5℃ / s, or when the monitoring data meets the conditions of carbon monoxide concentration ≥ 800ppm for a duration of 5 seconds and temperature rise ≥ 0.5℃ / s, the processor 51 determines that the disaster level of the energy storage device 100 is Level 3.

[0045] Step S4: Based on the disaster severity level, implement graded control of the disaster relief device to carry out disaster relief for the energy storage device 100.

[0046] In this invention, the disaster level of the energy storage device 100 is determined based on monitoring data, and the disaster extinguishing device is controlled in a graded manner according to the disaster level to extinguish the disaster on the energy storage device 100, thereby realizing the graded response strategy for fire control of the energy storage device 100 and taking differentiated intervention measures according to the development stage of the fire.

[0047] Please see Figure 5 Step S3 includes: Step S31: When the monitoring data comes from the first monitoring component, it is determined that cabinet 1 is in a state of disaster, and the disaster level of cabinet 1 is determined based on the monitoring data.

[0048] Step S32: When the monitoring data comes from the second monitoring component 32, it is determined that the battery module 2 corresponding to the monitoring data has a disaster, and the disaster level of the battery module 2 is determined according to the monitoring data.

[0049] Please see Figure 5 Step S4 includes: Step S41: When the disaster level is Level 1, control alarm component 42 to issue an alarm.

[0050] In some embodiments, when the disaster level of cabinet 1 is Level 1, the alarm control component 42 will issue an alarm; when the disaster level of battery module 2 is Level 1, the alarm control component 42 will also issue an alarm.

[0051] Step S42: When the disaster level is Level II, control the alarm component 42 to issue an alarm, control the explosion-proof valve component 44 to open, and start the fan 45.

[0052] In some embodiments, when the disaster level of cabinet 1 is level 2, the alarm component 42 is controlled to issue an alarm, the explosion-proof valve component 44 is controlled to open, and the fan 45 is started. When the disaster level of battery module 2 is level 1, the alarm component 42 is also controlled to issue an alarm, the explosion-proof valve component 44 is controlled to open, and the fan 45 is started.

[0053] It should be noted that when the disaster level is Level 1 or Level 2, the energy storage device 100 operates at reduced power.

[0054] Step S43: When the disaster level is level three, close the explosion-proof valve assembly 44 and the fan 45, and start the energy storage fire extinguishing assembly 41 to spray the fire extinguishing agent.

[0055] It should be noted that the energy storage device 100 will stop operating when the disaster level is level three.

[0056] By classifying disaster situations into levels, the system can make precise judgments and respond step by step according to the development stages of the disaster. It can issue an alarm at the first level of disaster to avoid unnecessary release of extinguishing agents. When the disaster further develops to the second level, an alarm is issued and the explosion-proof valve assembly 44 is opened and the fan 45 is started to connect the energy storage device 100 with the outside world. The flowing air is used to balance the pressure inside the energy storage device 100 and to expel toxic and harmful gases, smoke and dust from the energy storage device 100, thereby delaying or eliminating the escalation of the disaster level. When the disaster further develops to the third level, the energy storage fire extinguishing assembly 41 is activated to spray extinguishing agents for fire extinguishing. This significantly reduces the waste of extinguishing agents and secondary damage to the device while ensuring safety, lowers maintenance costs, and improves the rationality and economy of fire control. It realizes a progressive safety protection strategy from early warning and pressure relief to active fire extinguishing.

[0057] Please see Figure 5 Step S43 includes: Step S431: When there is a fire in cabinet 1 and the fire level is level three, activate the first energy storage fire extinguishing device 411 to spray the fire extinguishing agent.

[0058] It should be noted that when there is a level 3 disaster in cabinet 1, the processor 51 controls the first valve 4112 to open so that the first nozzle 4111 is connected to the auxiliary agent tank 414, thereby causing the first nozzle 4111 to spray fire extinguishing agent into cabinet 1.

[0059] Step S432: When there is a disaster in battery module 2, and the disaster level is level three, activate the corresponding second energy storage fire extinguishing device 412 to spray fire extinguishing agent.

[0060] It should be noted that when the battery module 2 is in a level 3 disaster situation, the processor 51 controls the second valve 4122 to open, so that the second nozzle 4121 is connected to the main agent tank 413, thereby causing the second nozzle 4121 to spray fire extinguishing agent onto the battery module 2.

[0061] Please see Figure 5 Step S43 also includes: Step S433: When the extinguishing agent of the second energy storage fire extinguishing device 412 is exhausted, and the battery module 2 is still in a state of disaster, and the disaster level is a level three disaster, the first energy storage fire extinguishing device 411 is activated to spray the extinguishing agent.

[0062] It should be noted that when the extinguishing agent of the second energy storage fire extinguishing device 412 is exhausted, and the battery module 2 is still in a state of disaster, and the disaster level is level three, the disaster of the battery module 2 will spread to the cabinet 1.

[0063] Step S433 can compensate for the limited extinguishing agent storage of the first energy storage extinguishing device 411, which cannot continue disaster response after spraying, thereby improving safety redundancy and the reliability of disaster response.

[0064] Please see Figure 5 Step S4 also includes: Step S44: During the process of the fire extinguishing agent being sprayed by the energy storage fire extinguishing component 41, the monitoring data detected by the disaster monitoring device 3 continues to be acquired.

[0065] Step S45: When it is determined from the monitoring data that the disaster in the energy storage device 100 has been extinguished, shut down the energy storage fire extinguishing component 41.

[0066] In some embodiments, when it is determined from monitoring data from the first monitoring component that the fire in cabinet 1 has been extinguished, the processor 51 controls the first valve 4112 to close, thereby disconnecting the first nozzle 4111 and the auxiliary agent tank 414, and thus shutting down the first energy storage extinguishing device 411.

[0067] In some embodiments, when it is determined from monitoring data from the second monitoring component 32 that the fire in the battery module 2 has been extinguished, the processor 51 controls the first valve 4112 to close, thereby disconnecting the first nozzle 4111 and the auxiliary agent tank 414, and thus shutting down the first energy storage extinguishing component 411.

[0068] Step S46: When the extinguishing agent of the energy storage fire extinguishing component 41 is exhausted and the monitoring data determines that there is still a disaster in the energy storage device 100, shut down the energy storage fire extinguishing component 41 and start the sprinkler component 43 to spray liquid.

[0069] It should be noted that in step S46, the processor 51 controls the third valve 4322 to open so that the third nozzle 4321 is connected to the liquid storage tank 431, thereby allowing the third nozzle 4321 to spray liquid onto the battery module 2 and the cabinet 1.

[0070] In some embodiments, during a Level 3 disaster in cabinet 1, but without a Level 3 disaster in battery module 2, or during a Level 3 disaster in battery module 2, the disaster spreads to cabinet 1, causing a disaster in cabinet 1. After the extinguishing agent in auxiliary agent tank 414 is exhausted, the first energy storage extinguishing device 411 is shut down, and the spray assembly 43 is activated to spray liquid.

[0071] Step S46 can compensate for the limited extinguishing agent storage capacity of the energy storage fire extinguishing component 41, which cannot continue disaster response after spraying, thereby improving safety redundancy and the reliability of disaster response.

[0072] Please see Figure 5 Step S4 also includes: Step S47: During the spraying operation of the spray assembly 43, when it is determined from the monitoring data that the disaster in the energy storage device 100 has been extinguished, the spray assembly 43 is shut down.

[0073] It should be noted that in step S46, the processor 51 controls the closing of the third valve 4322 to disconnect the third nozzle 4321 and the liquid storage chamber, thereby shutting down the spray assembly 43.

[0074] Step S48: When the liquid in the storage tank 431 of the spray assembly 43 is depleted, and it is determined from the monitoring data that the energy storage device 100 is still in a state of disaster, a disaster information is sent to the user terminal.

[0075] In some embodiments, the management server 8 sends disaster information to user terminals through a cloud platform.

[0076] It should be noted that the system sends disaster information to the user terminal, reminding the user to arrive at the scene to handle the disaster. Specifically, it instructs the user to connect the fire hydrant component 7 to the fire pipeline, thereby supplying liquid into cabinet 1 to handle the disaster. This establishes a manual intervention trigger mechanism, which can promptly inform the user of the scene status when automatic fire suppression systems fail, enabling the user to quickly rush to the scene to carry out manual firefighting and prevent the disaster from spreading out of control. Furthermore, if the disaster cannot be controlled during manual handling, measures such as calling professional firefighting forces can be taken.

[0077] Please see Figure 6 , Figure 6 This is another flowchart of a second embodiment of the fire control method for the energy storage device 100 of the present invention, the method further comprising: Step S5: Send the disaster level of battery module 2 and the disaster level of cabinet 1 to management server 8 so that management server 8 can display the disaster level of battery module 2 and the disaster level of cabinet 1.

[0078] In some embodiments, the processor 51 sends the disaster level of the battery module 2 and the disaster level of the cabinet 1 to the management server 8.

[0079] In this invention, by adding step S5, the historical data tracing and fire status monitoring of the energy storage device 100 are realized.

[0080] It should be noted that when the energy storage device 100 is in the event of a disaster, at least one processor 51 is capable of executing the fire control method of the energy storage device 100 described above.
