One port of the tee joint structure is positioned in the battery pack, and the other two ports are communicated with the upper battery pack and the lower battery pack. The fire detection tube is inserted into the opening in the battery pack, and is wound on the top of the explosion venting valve of each battery cell, and when the battery cells are discharged, the fire detection tube is burned by high-temperature gas or flame, so that the fire extinguishing agent is sprayed into the battery pack for cooling, and the battery cells are prevented from burning.
The fire-fighting host 60 is in communication connection with the environment detection device 30 and the battery temperature management device 40, acquires the temperature information of each battery core in each battery pack 20 and the environment information fed back by the environment detection device 40, and controls the fire extinguishing agent in the fire-extinguishing container 501 to enter the battery pack 20 reaching the preset battery temperature fire-extinguishing condition through the first conveying pipeline 502 when the temperature information of the battery pack and/or the environment information meet the preset secondary alarm condition; when the temperature information of the battery packs and/or the environmental information meet preset three-level alarm conditions, the fire extinguishing agent in the fire extinguishing container 501 is controlled to enter each battery pack 20 through the first conveying pipeline 502 and enter each bin-level fire extinguishing nozzle 504 through the second conveying pipeline 503.
In one example, the preset battery temperature fire extinguishing conditions include: one cell temperature is more than or equal to T0 and the other two cells temperature is more than or equal to T1 in the same battery pack, wherein T0 is more than T1.
In other examples, the preset battery temperature fire extinguishing conditions further include: two battery cells exist in the same battery pack, and the temperature of the two battery cells is more than or equal to T2.
In an example, a multi-stage alarm condition and a multi-stage alarm response scheme are preset in the fire-fighting host 60, the temperature information of the battery pack, the environmental information and the preset multi-stage alarm condition are matched, a matching result can be obtained, and then the corresponding alarm response scheme is adopted for responding according to the matching result. As an embodiment, the present invention provides an implementation scheme of a three-level alarm mechanism, which specifically includes:
First case (first level alarm): when any one of the sensing information (including sensing information detected by various sensors provided in the container body 10 and temperature information detected by a temperature sensor provided in the battery pack 20) reaches its corresponding alarm threshold, a primary alarm response scheme is started. In one example, the fire suppression control system further comprises an audible and visual alarm 703 and/or a CMU (Container Monitoring Unit ), the primary alarm response scheme comprising: the fire host 60 controls the activation of an audible and visual alarm device (e.g., a buzzer) and/or outputs a primary alarm message to the CMU.
The step of enabling any sensing information to reach the corresponding alarm threshold value comprises the following steps: the temperature of any one of the battery cells of any one of the battery packs 20 reaches a preset temperature alarm threshold, or the concentration of the combustible gas reaches a preset gas concentration alarm threshold, or when the concentration of the smoke reaches a preset smoke concentration alarm threshold, or the temperature in the container body reaches a preset container body temperature alarm threshold, or the temperature change in the container body reaches a preset temperature change alarm threshold, or the PM2.5 in the container body reaches a preset PM2.5 threshold, etc.
Second case (second level alarm): when any one of the battery packs 20 reaches a battery temperature fire extinguishing condition, or when any one of the battery packs reaches a battery temperature fire extinguishing condition and one of the combustible gas concentration, the smoke concentration, the temperature in the container body, and the temperature change in the container body reaches a corresponding alarm threshold, a secondary alarm response scheme (i.e., a battery pack level fire extinguishing scheme) is initiated. The secondary alarm response scheme includes: fire-fighting host 60 controls the passage of fire extinguishing agent in fire-extinguishing container 501 via first delivery conduit 502 into battery pack 20 reaching battery temperature fire-extinguishing conditions.
In one example, when the fire conduit assembly 50 further includes a selector valve and/or a zone control valve, the activation of the secondary alarm response scheme is specifically: the fire-fighting host 60 controls the selection valve 505 to be in the first selection state and/or controls the zone control valve 506 corresponding to the battery pack 20 reaching the battery temperature fire-extinguishing condition to be opened, so that the fire extinguishing agent in the fire-extinguishing container 501 enters the battery pack 20 reaching the battery temperature fire-extinguishing condition through the first conveying pipeline 502. Taking the fire protection layouts of fig. 4 and 5 as an example, initiating the secondary alarm response scheme includes: the fire-fighting host 60 controls the selection valve 505 to be in the first selection state for a first preset time (for example, 180 s), and simultaneously controls the zone control valves 506 corresponding to the battery packs reaching the battery temperature fire-extinguishing condition to be opened for the first preset time, and the other zone control battery valves 506 do not process (default to be in the closed state). At this time, the fire extinguishing agent in the fire extinguishing container 501 enters the battery pack that reaches the battery temperature fire extinguishing condition via the third transfer duct 507, the selector valve 505, the fourth transfer duct 508, the zone control valve 506, and the first transfer duct 502. When the first preset time is reached, the selector valve 505 and the zone control valve 506 are reset. After reset, the fire engine 60 responds accordingly according to the latest matching result.
It will be appreciated that the fire extinguishing agent enters the battery pack reaching the battery temperature fire extinguishing condition and enters the fire detection tube of other battery packs under the zone control battery valve corresponding to the battery pack. However, only the fire probe of the battery pack, which reaches the battery temperature fire extinguishing condition, will burst under the influence of high temperature (the bursting temperature of the fire probe is generally higher than the aforementioned T0), so that the fire extinguishing agent is sprayed into the battery pack.
Third scenario (three level alarm): when two kinds of appointed sensing information in the container body reach the corresponding alarm threshold value, a three-level alarm response scheme (namely a bin level fire extinguishing scheme) is started. The three-level alarm response scheme comprises the following steps: fire-fighting host 60 controls the entry of fire suppressant in fire-suppressing container 501 into each battery pack 20 via first delivery conduit 502 and into each bin level fire-fighting nozzle 504 via second delivery conduit 503.
Wherein, appointed two kinds of sensing information in the container box reach its warning threshold that corresponds includes: the concentration of the combustible gas reaches a preset gas concentration alarm threshold or the concentration of the smoke reaches a preset smoke concentration alarm threshold, and the temperature change in the container body reaches a preset temperature change alarm threshold or the temperature in the container body reaches a preset temperature alarm threshold in the container body.
In one example, when the fire conduit assembly 50 further includes a selector valve 505 and/or a zone control valve 506, the three-level alarm response scheme is initiated specifically as follows: the fire-fighting host 60 controls the selection valve 505 to be in the second selection state and/or controls each zone control valve 506 to be opened, so that the fire extinguishing agent in the fire-extinguishing container 501 enters each battery pack 20 through the first conveying pipe 502, and the fire extinguishing agent in the fire-extinguishing container 501 enters each bin-level fire-extinguishing nozzle 504 through the second conveying pipe 503. Taking the fire protection layouts of fig. 4 and 5 as an example, initiating the three-level alarm response scheme includes: the fire-fighting host 60 controls the selection valve 505 to be in the second selection state for a second preset time (for example, 100 s), and simultaneously controls the zone control valves 506 on both the upper and lower sides to be opened for the second preset time. At this time, the fire extinguishing agent in the fire extinguishing container 501 enters each of the battery packs 20 through the third conveying pipe 507, the selector valve 505, the fourth conveying pipe 508, the zone control valve 506 and the first conveying pipe 502, and the fire extinguishing agent in the fire extinguishing container 501 enters the four bin-level fire extinguishing nozzles 504 through the third conveying pipe 507, the selector valve 505 and the second conveying pipe 503 to be ejected. When the second preset time is reached, the selector valve 505 and the zone control valve 506 are reset. After reset, the fire engine 60 responds accordingly according to the latest matching result.
In some embodiments, because the temperature in the container 10 is high in summer, when judging whether the battery pack 20 meets the battery temperature fire extinguishing condition according to the temperature information of each battery cell in the battery pack 20, the false alarm rate is high, and in order to reduce the false alarm rate, the temperature sensor in the battery pack 20 may be shielded. To accommodate this, a second temperature sensor is provided in the gas sensor 301, which is used to detect the temperature in the container 10, and may replace the temperature sensor in the battery pack 20, and to design a corresponding alarm threshold according to the actual conditions.
It should be noted that the above-mentioned alarm conditions of each stage are only exemplary, and are not limiting of the present invention. Those skilled in the art can make settings based on temperature information and/or environmental information of the battery pack as required.
In one example, the fire suppression control system further includes a deflation indicator light 704, and the secondary alarm response scheme and the tertiary alarm response scheme further include: the fire engine 60 controls the deflation indicator light 704 to be turned on and the audible and visual alarm 703 to be activated, and outputs secondary alarm information or tertiary alarm information to the CMU. In addition, the fire engine 60 is also used to control the energy storage system to stop charging and discharging, turn off the ventilation fan 709, etc. The specific control logic can be set according to the requirements.
In general, the temperature detection feedback of the battery temperature management device 40 to the battery cell is earlier than the feedback of the gas sensor 301 to the concentration of the combustible gas, the feedback of the gas sensor 301 to the concentration of the combustible gas is earlier than the feedback of the smoke sensor 302 to the concentration of the smoke, and the feedback of the smoke sensor 302 to the concentration of the smoke is earlier than the feedback of the first temperature sensor 303 to the temperature change in the container 10. Therefore, when the energy storage system breaks out a fire, the energy storage system is generally gradually transited from the primary alarm to the tertiary alarm, and if the fire is not developed quickly, the fire is generally destroyed in the primary alarm or the secondary alarm and cannot enter the tertiary alarm.
In one example, the battery temperature management device 40 may also send a fire-extinguishing initiation signal directly to the fire-fighting host 60, and after the fire-extinguishing initiation signal is received by the fire-fighting host 60, the secondary alarm response scheme is initiated. Specifically, the battery temperature management device 40 determines whether each battery pack 20 reaches the battery temperature fire extinguishing condition according to the temperature information of each battery cell in each battery pack 20, and if so, outputs a fire extinguishing start signal to the fire-fighting host 60. The fire suppression initiation signal is also associated with a zone control valve 506 corresponding to the battery pack reaching the battery temperature fire suppression condition. For example, fig. 4 includes upper and lower zone control valves 506, and when the upper battery pack 20 reaches the battery temperature fire extinguishing condition, the battery temperature management device 40 outputs a first fire extinguishing start signal to the fire-fighting host 60, and when the lower battery pack 20 reaches the battery temperature fire extinguishing condition, the battery temperature management device 40 outputs a second fire extinguishing start signal to the fire-fighting host 60. In one example, the fire suppression initiation signal is a dry-contact passive switch, while the battery temperature management device 40 also outputs the fire suppression initiation signal to the fire host 60 via a communication connection. The fire host 60, upon receiving the fire suppression initiation signal, initiates a secondary alarm response scheme. Specifically, when the fire-fighting host 60 receives the first fire-extinguishing start signal, the upper zone control valve 506 is opened, and the fire extinguishing agent in the fire-extinguishing container 501 is controlled to enter each battery pack 20 controlled by the upper zone control valve 506 through the first conveying pipeline 502; when the fire-fighting host 60 receives the second fire-extinguishing start signal, the lower zone control valve 506 is opened, and the fire extinguishing agent in the fire-extinguishing container 501 is controlled to enter each battery pack 20 controlled by the lower zone control valve 506 through the first conveying pipe 502.
In other examples, the CMU may also send a fire suppression initiation signal to the fire host 60. For example, the CMU sends a first fire suppression initiation signal (corresponding to clusters 1-5) or a second fire suppression initiation signal (corresponding to clusters 6-10) to the fire host 60. The processing manner of the fire-extinguishing host 60 receiving the fire-extinguishing start signal is the same as that in the previous example, and will not be described here again.
In an example, the fire suppression control system further comprises a ventilation fan 709 and/or a water fire control device, and the fire control host 60 is further configured to control the smoke exhaust fan to start and/or the water fire control device to spray water when the environmental information reaches a preset fire linkage condition. As shown in fig. 3, two ventilation fans 709 and a water fire interface 710 are provided at the sides of the container body. The two ventilation fans 709 are communicatively connected to the fire engine 60, and the fire engine 60 controls the two ventilation fans 709 to rotate when the environmental information reaches a preset smoke evacuation and fire control linkage condition (for example, the concentration of the combustible gas in the container 10 reaches a preset smoke evacuation concentration threshold). The water fire-fighting device comprises a water fire-fighting interface 710 and a plurality of water fire-fighting spray heads 711, wherein one end of the water fire-fighting interface 710 is communicated with the plurality of water fire-fighting spray heads 711 through fire-fighting water pipes, and the other end of the water fire-fighting interface 710 is externally connected with a standard fire-fighting water pipe to be connected with a water fire-fighting system, or water fire-fighting equipment is configured on site and is pre-installed with the water fire-fighting interface 711 on a container. The fire engine 60 establishes communication connection with the water fire system or the water fire equipment, and controls the water fire device to spray water when the environmental information reaches a preset water fire linkage condition (for example, the temperature in the container body 10 reaches a preset water fire temperature threshold). In the example, a three-stage water fire-fighting scheme is also realized on the basis of a two-stage linkage scheme for realizing air fire-fighting.
The fire extinguishing control system of the energy storage container provided by the embodiment of the invention comprises an environment detection device, a battery temperature management device, a fire control pipeline assembly and a fire control host; the environment detection device is used for detecting environment information in the container body; the battery temperature management device is used for acquiring temperature information of each battery cell in each battery pack; the fire-fighting host computer is used for starting a battery pack level fire-extinguishing scheme when the temperature information and/or the environmental information of the battery pack meet the preset secondary alarm condition, and carrying out targeted fire extinguishment on the battery pack reaching the battery temperature fire-extinguishing condition; and when the temperature information and/or the environmental information of the battery packs meet preset three-level alarm conditions, starting a bin-level fire extinguishing scheme, and submerging the fire extinguishing agent into each bin-level gas fire extinguishing spray head of each battery pack and each container. By adopting the invention, two-stage linkage of gas fire-fighting in battery pack-level fire-fighting and bin-level fire-fighting is realized through one set of system, so that the invention has the advantages of simple design structure, small occupied area and reduced cost of the fire-fighting system.
