By way of example, the method is applied to the air exhaust control process of the energy storage container, and the air exhaust control device of the energy storage container can comprise a server or electronic equipment. The method comprises the following steps S501-S504, wherein,

s501: and acquiring the temperature, the smoke concentration and the gas concentration of the battery cluster arranged at each position in the energy storage container within a preset time.

For example, during the first preset time period, the internal temperature of the energy storage container is 29 degrees celsius, the concentration of PM2.5 is 400 mg/cubic meter, and the gas concentration is 200ppm.

For example, an energy storage container is a new energy storage box which is composed of a charger, an inverter, a storage battery, an isolation transformer, a change-over switch and the like and inverts direct current electric energy into alternating current electric energy. The energy storage container system is an integrated energy storage system developed aiming at the requirements of a mobile energy storage market, a battery cabinet, a lithium battery management system and a container video control system are integrated in the energy storage container system, and an energy storage converter and an energy management system can be integrated according to the requirements of customers. The container energy storage system has the characteristics of simplified infrastructure construction cost, short construction period, high modularization degree, convenience in transportation and installation and the like, and can be suitable for application occasions such as firepower, wind energy, solar energy, islands, districts, schools, scientific research institutions, factories, large-scale load centers and the like.

For example, the battery cluster and the energy storage inverter can form an energy storage system, most of the battery cluster and the energy storage inverter adopt lithium iron phosphate as an energy storage medium, the direct-current voltage range of the battery cluster can meet the basic power consumption requirement, a single cluster and a single energy storage converter can form the energy storage system, and the power of the energy storage converter can be correspondingly increased when a plurality of clusters are connected in parallel. The battery cluster adopts a modular design, can flexibly configure capacity, and can realize quick installation and deployment with a container.

S502: within a first preset time, when detecting that part or all of the battery clusters in the energy storage container are abnormal, determining that the battery clusters in the energy storage container are in the abnormal position information, wherein the abnormal condition comprises at least one of a first temperature increase value exceeding a preset temperature increase value, a first smoke concentration increase value exceeding a preset smoke concentration increase value or a first gas concentration increase value exceeding a preset gas concentration increase value.

For example, within a first preset time period, if the first temperature increase value is 15 degrees celsius and the preset temperature increase value is 10 degrees celsius, the first temperature increase value exceeds the preset temperature increase value; the first smoke concentration increase value is 600 mg/cubic meter, and the preset smoke concentration increase value is 300 mg/cubic meter, so that the first smoke concentration increase value exceeds the preset smoke concentration increase value; the first gas concentration increase value is 200ppm, the preset gas concentration increase value is 100ppm, and then the first gas concentration increase value exceeds the preset gas concentration increase value.

In one possible example, step S502 includes the steps of, wherein,

b1: and in a second preset time period, when at least one of the conditions that the difference value between the second temperature increment value and the first temperature increment value exceeds a first preset value, the difference value between the second smoke concentration increment value and the first smoke concentration increment value exceeds a second preset value and the difference value between the second gas concentration increment value and the first gas concentration increment value exceeds a third preset value occurs, controlling all exhaust fans in the area of the battery cluster to rotate at the maximum rotating speed.

For example, within a second preset time period, if the first temperature increase value is 15 degrees celsius, the second temperature increase value is 50 degrees celsius, the difference between the second temperature increase value and the first temperature increase value is 35 degrees celsius, and the first preset value is 10 degrees celsius, the difference between the second temperature increase value and the first temperature increase value exceeds the first preset value; the first smoke concentration increase value is 600 mg/cubic meter, the second smoke concentration increase value is 100 mg/cubic meter, the difference value between the second smoke concentration increase value and the first smoke concentration increase value is 500 mg/cubic meter, and the second preset value is 200 mg/cubic meter, so that the difference value between the second smoke concentration increase value and the first smoke concentration increase value exceeds the second preset value; the first gas concentration increase is 100ppm, the second gas concentration increase is 500ppm, the difference between the second gas concentration increase and the first gas concentration increase is 400ppm, and the third preset value is 200ppm, so that the difference between the second gas concentration increase and the first gas concentration increase exceeds the third preset value.

For example, the temperature, smoke concentration, and gas concentration can be detected in real time by using a temperature-sensitive detection device, a smoke-sensitive detection device, and a gas concentration detection device, and the temperature-sensitive detection device, the smoke-sensitive detection device, and the gas concentration detection device have the capability of detecting temperature, smoke concentration, and gas concentration continuously for 24 hours all day.

For example, the gas concentration includes the concentration of combustible gas, such as carbon monoxide, hydrogen, oxygen, natural gas, methane, ethane, acetylene, ethanol, propane, propylene, butylene, methyl ether, vinyl chloride, liquefied petroleum gas, isobutene, and the like, and the present application is not limited thereto. The hazard of combustible gases as described in more detail below, the homogeneous mixture of combustible gas and combustion supporting gas can cause explosion or combustion under extreme conditions. The combustion-supporting gas may be air, oxygen or other combustion-supporting gas. The explosion limit is generally referred to as the concentration limit of the combustible gas in air. The lowest content of combustible gas capable of causing an explosion is called the lower explosion limit; the highest concentration is referred to as the upper explosive limit. The mixed systems differ in their composition and in their explosive limits. In the same mixing system, the explosion limit can be changed due to the initial temperature, the system pressure, the content of inert medium, the space and the material of the wall of the mixing system, the magnitude of ignition energy and the like. The general rule is as follows: when the original temperature of the mixed system is increased, the explosion limit range is increased, i.e., the lower limit is lowered and the upper limit is raised. As the temperature of the system rises, the molecular internal energy increases, so that the original non-combustible mixture becomes a combustible and explosive system. The system pressure is increased, and the explosion limit range is also enlarged, because the system pressure is increased, the distance between molecules is closer, the collision probability is increased, and the combustion reaction is easier to carry out. When the pressure is reduced, the explosion limit range is reduced; when the pressure drops to a certain value, the upper limit coincides with the lower limit, and the corresponding pressure is called the critical pressure of the mixing system. When the pressure drops below the critical pressure, the system will not become an explosive system (individual gases have abnormal phenomena). In this regard, the exhaust fan can effectively reduce the gas concentration and the air pressure by exhausting air, thereby reducing the risk.

In one possible example, step S502 includes the following steps B2-B4, wherein:

b2: the temperature increase is obtained by subtracting the temperature measured n from the temperature measured n + 1.

B3: the smoke concentration measured n +1 minus the smoke concentration measured n is the smoke concentration increase.

B4: the gas concentration measured n +1 minus the gas concentration measured n is the gas concentration increase.

For example, within 5 minutes, the temperature measured at the 3 rd minus the temperature measured at the 2 nd is the temperature increase, the smoke concentration measured at the 3 rd minus the smoke concentration measured at the 2 nd is the smoke concentration increase, and the gas concentration measured at the 3 rd minus the gas concentration measured at the 2 nd is the gas concentration increase.

S503: generating an exhaust fan control scheme according to the abnormal condition and the simulation model, wherein the exhaust fan control scheme comprises the following steps: the position of the activated exhaust fans, the number of the activated exhaust fans, and the rotational speed of each exhaust fan.

Implementation of the exhaust fan control scheme requires assurance of the exhaust

The fan control scheme enables the total exhaust volume per minute to be not less than the volume of the energy storage container, and the specific method is that a plurality of exhaust fans are adjusted to synchronously work according to the establishment of the exhaust fan control scheme, and in one case, the exhaust fans with higher smoke concentration or higher temperature work at the maximum rotating speed (for example, the rotating speed of the fan is preferably preset to be 3000 r/min), and the rotating speeds of other fans can be set to be lower (for example, 1500 r/min or 2000 r/min).

In one possible example, step S503 includes the following steps C1-C3:

c1: when at least one of the temperature increase value in a first preset range, the smoke concentration increase value in a second preset range and the gas concentration increase value in a third preset range occurs, controlling the rotation speed of the exhaust fan to be a preset rotation speed;

c2: when at least one of the temperature increase value exceeds a first preset range, the smoke concentration increase value exceeds a second preset range and the gas concentration increase value exceeds a third preset range, controlling the rotating speed of the exhaust fan to be the maximum rotating speed;

c3: and uploading the exhaust fan control scheme to an exhaust server, wherein the exhaust server can interact with terminal equipment, and the terminal equipment controls the exhaust fan through the exhaust server.

For example, when at least one of the temperature increase value is 5-10 ℃, the smoke concentration increase value is 50-100 mg/m, and the gas concentration increase value is 50-100 ppm, the rotation speed of the exhaust fan is controlled to be 1500 rpm. And when at least one of the temperature increase value of 10-50 ℃, the smoke concentration increase value of 100-500 mg/cubic meter and the gas concentration increase value of 100-500 ppm occurs, controlling the rotation speed of the exhaust fan to be 5000 r/min. And when at least one of the temperature increase value of 50-200 ℃, the smoke concentration increase value of 500-2000 mg/cubic meter and the gas concentration increase value of 500-2000 ppm occurs, controlling the rotation speed of the exhaust fan to 10000 r/min. The preset rotating speed can be regulated and controlled according to conditions, and when at least one of the temperature increase value exceeding 200 ℃, the smoke concentration increase value exceeding 2000 mg/cubic meter and the gas concentration increase value exceeding 2000ppm occurs, the exhaust fan is controlled to exhaust air at the maximum rotating speed. In addition, it should be noted that when the temperature increase value is a, the smoke concentration increase value is B, and the gas concentration increase value is C, the exhaust fan rotation speed is theoretically 1000 rpm according to the temperature increase value a, the exhaust fan rotation speed is theoretically 2000 rpm according to the smoke concentration increase value B, and the exhaust fan rotation speed is theoretically 3000 rpm according to the gas concentration increase value C, the selection is performed according to the condition that the exhaust fan rotation speed is maximum, that is, the rotation speed of the exhaust fan is controlled to be 3000 rpm.

For example, the rotation speed of the fan is the number of rotations per minute of the fan blade. The rotation speed of the exhaust fan can be controlled by controlling the working voltage and the rotation speed gear number of the motor, and under the condition that the structure of the fan is fixed, the rotation speed of a direct current fan (namely, a fan using direct current) is synchronously changed along with the change of the working voltage. For example, the exhaust fan speed is set to 3000 rpm as 1 gear, 8000 rpm as 2 gear, and 15000 rpm as 3 gear, and the exhaust fan speed can be adjusted according to different environmental conditions.

In the embodiments provided by the present application, the geometric parameters of the energy storage container, the geometric parameters of the distributed battery clusters in the energy storage container, the geometric parameters of the battery clusters, the electrochemical parameters, and the thermal parameters are obtained. Establishing an electrochemical model of the battery to be modeled according to electrochemical parameters of the battery; the electrochemical model comprises a charge conservation sub-model, a mass conservation sub-model, an electrode dynamics sub-model and an energy conservation sub-model; establishing a thermal model of the battery to be modeled according to thermal parameters of the battery; coupling an electrochemical model and a thermal model through a three-dimensional model to form a simulation model, wherein the heat generation rate output by the electrochemical model is input into the thermal model to simulate that an electrochemical process generates heat to change the temperature of a battery; the temperature output by the thermal model is input to the electrochemical model to simulate the physical quantity in the electrochemical process influenced by the change of the temperature; the electrochemical model calculates the heat production rate of the battery, and then the heat production rate is used as a heat source of the thermal model to calculate the internal temperature field of the battery; the temperature output by the thermal model of the electrochemical model adjusts electrochemical parameters so as to realize the coupling of the electrochemical model and the thermal model.

At present, a simulation model can be established by PyroSim software, and parameters of an exhaust fan can be led in by PyroSim so as to simulate the situation that the exhaust fan is started by an energy storage container to cool down a battery cluster.

In the embodiment provided by the application, after the abnormal condition is input into the simulation model, the position of starting the exhaust fan can be adjusted to carry out simulation, and the simulation results of starting the fan at different positions are obtained. The number of the started exhaust fans can be adjusted, and simulation results of starting different fans can be obtained. The rotating speed of the opened exhaust fan can be adjusted, and simulation results of different rotating speeds of the opened exhaust fan are obtained.

The simulation result may be at least one of a simulated increase in temperature, a simulated increase in smoke concentration, and a simulated increase in concentration of the first gas for the battery cluster.

When the exhaust fan control scheme is determined, if the exhaust fan at the position a is started, the abnormal condition improvement effect of the battery cluster is optimal compared with the fans at other positions, and the position a can be determined to be the optimal position for starting the exhaust fan.

If n exhaust fans are started, compared with the fans with the starting number, the abnormal condition improvement effect of the battery cluster is optimal, and the optimal number of the fans for starting the n exhaust fans can be determined.

If the rotating speed of each exhaust fan which is started is omega, the abnormal condition improvement effect of the battery cluster is optimal compared with other rotating speeds of the exhaust fans which are started, and the starting rotating speed omega of the exhaust fans can be determined to be the optimal rotating speed.

In a possible example, the simulating, by the simulation module, starting the exhaust fan to obtain a simulation result includes:

taking the position of the battery cluster in the energy storage container with the abnormal condition as a central position, and sequentially increasing the number of the exhaust fans to be started from near to far;

gradually increasing the rotating speed of the opened exhaust fan;

S504: when detecting that part or all of the battery clusters in the energy storage container are out of control, controlling all exhaust fans in the battery cluster region in which the thermal runaway occurs to rotate at the maximum rotation speed, and controlling the air of the exhaust fans to blow from the region with low temperature to the region with high temperature.

For example, according to the exhaust fan control scheme, when the thermal runaway of the battery cluster is detected, all exhaust fans in the area of the battery cluster are controlled to rotate at 10000 rpm, and the air of the exhaust fans is controlled to blow from the area with low temperature to the area with high temperature, at the moment, the thermal runaway is controlled to the area as much as possible, and the possibility that the thermal runaway diffuses to other areas in the energy storage container is reduced.

S505: when detecting energy storage container part or whole the battery cluster takes place during the abnormal conditions, will the interior region of energy storage container is according to the distance apart from the entrance, divide into first interior region, second interior region and third interior region by near to far away, works as the thermal runaway is located during the third interior region, control the third interior region's exhaust fan rotational speed be maximum rotational speed first interior region's exhaust fan rotational speed be minimum rotational speed and the second interior region's exhaust fan rotational speed is in between maximum rotational speed and the minimum rotational speed, exhaust fan rotational speed and exhaust fan quantity calculate according to the interior volume that total exhaust volume of per second is not less than energy storage container.

For example, according to exhaust fan control scheme, when detecting energy storage container part or whole the battery cluster takes place during abnormal conditions, will the interior region of energy storage container is according to the distance apart from the entrance, by nearly dividing into first interior region, second interior region and third interior region far away, when thermal runaway is located the third interior region, the exhaust fan rotational speed of control third interior region is 10000 revolutions per minute, and first interior region's exhaust fan rotational speed is 1000 revolutions per minute, and second interior region's exhaust fan rotational speed is 3000 revolutions per minute, exhaust fan rotational speed and exhaust fan quantity calculate according to the internal volume that total exhaust volume of per second is not less than energy storage container.

For example, implement the in-process of exhaust fan control scheme, guarantee all the time exhaust fan control scheme makes total exhaust volume per second not less than the volume of energy storage container, specifically speaking, control a plurality of exhaust fans and carry out synchronous work according to exhaust fan control scheme's establishment for smog concentration is the highest, the regional exhaust fan that the temperature is the highest or gas concentration is worked with maximum rotational speed (for example predetermine fan rotational speed and be 10000 revolutions per minute), and other fan rotational speeds are 2000 revolutions per minute.

S506: and when the abnormal condition of part or all of the battery clusters in the energy storage container is detected, controlling the wind of the three regional exhaust fans to blow to the region with the abnormal condition.

For example, according to the exhaust fan control scheme, when it is detected that the smoke concentration in the second internal area of the battery cluster is over-high, the air of the exhaust fans in the first internal area, the second internal area and the third internal area is blown to the second internal area, so that the diffusion of the smoke concentration is reduced, and the influence on other internal areas is reduced.

It should be noted that, after the fire-fighting host completes the operation of the exhaust fan control scheme, the exhaust fan control scheme and the video processed on site are sent to the electronic terminal of the administrator, and the administrator can check details through the electronic terminal.
