As an example, this method is applied to the energy storage container exhaust control process. The energy storage container exhaust control device may include a server or electronic equipment. The method includes the following steps S501-S504, wherein:

S501: Obtain the temperature, smoke concentration and gas concentration of the battery cluster installed at each location inside the energy storage container within a preset period of 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 200 ppm.

For example, an energy storage container is a new energy storage box that inverts DC power into AC power, consisting of chargers, inverters, batteries, isolation transformers and switches. The energy storage container system is an integrated energy storage system developed to meet the needs of the mobile energy storage market. It integrates battery cabinets, lithium battery management systems and container video control systems, and can integrate energy storage converters and energy management according to customer needs. system. Container energy storage systems have the characteristics of simplified infrastructure construction costs, short construction period, high degree of modularity, easy transportation and installation, etc., and can be applied to thermal power, wind energy, solar energy, islands, communities, schools, scientific research institutions, factories and large load centers and other applications.

For example, battery clusters can be combined with energy storage inverters to form an energy storage system. Most of them use lithium iron phosphate as the energy storage medium. Their DC voltage range can meet basic power needs. A single cluster can be combined with a stand-alone energy storage inverter. In the energy storage system, when multiple clusters are connected in parallel, the power of the energy storage converter can be increased accordingly. The battery cluster adopts a modular design, which can flexibly configure the capacity and enable rapid installation and deployment with containers.

S502: Within the first preset time period, when an abnormality is detected in some or all of the battery clusters in the energy storage container, determine that the battery cluster in which the abnormality occurs is located in the energy storage container. Information, the abnormal situation includes at least one of the first temperature increase value exceeding the preset temperature increase value, the first smoke concentration increase value exceeding the preset smoke concentration increase value, or the first gas concentration increase value exceeding the preset gas concentration increase value. item.

For example, within the first preset time period, the first temperature increase value is 15 degrees Celsius, and the preset temperature increase value is 10 degrees Celsius, then the first temperature increase value exceeds the preset temperature increase value; the first smoke concentration increase value is 600 mg/m3, the preset smoke concentration increment value is 300 mg/m3, then the first smoke concentration increment value exceeds the preset smoke concentration increment value; the first gas concentration increment value is 200ppm, and the preset gas concentration increment value is 100ppm , then the first gas concentration increase value exceeds the preset gas concentration increase value.

In a possible example, step S502 includes the following steps, wherein:

B1: Within the second preset time period, the difference between the second temperature increase value and the first temperature increase value exceeds the first preset value, and the difference between the second smoke concentration increase value and the first smoke concentration increase value exceeds the second When at least one of the preset value and the difference between the second gas concentration increase value and the first gas concentration increase value exceeds the third preset value, all exhaust fans in the area of the battery cluster are controlled to rotate at maximum speed.

For example, within the second preset time period, 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 temperature increase value is 35 degrees Celsius. The preset value is 10 degrees Celsius, then 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, and the second smoke concentration increase value is 100 mg/cubic meter, the difference between the second smoke concentration increased value and the first smoke concentration increased value is 500 mg/cubic meter, and the second preset value is 200 mg/cubic meter, then the second smoke concentration increased value is different from the first smoke concentration increased value. The difference in the smoke concentration increase value exceeds the second preset value; the first gas concentration increase value is 100ppm, the second gas concentration increase value is 500ppm, and the difference between the second gas concentration increase value and the first gas concentration increase value is 400ppm. , the third preset value is 200 ppm, then the difference between the second gas concentration increase value and the first gas concentration increase value exceeds the third preset value.

For example, the temperature is detected using a temperature sensor detection device, the smoke concentration is detected using a smoke sensor detection device, and the gas concentration is detected using a gas concentration detection device. The above temperature sensor detection device, smoke sensor detection device and gas concentration detection device can detect the temperature in real time. Detects temperature, smoke concentration and gas concentration, and has the ability to detect 24 hours a day.

For example, the above-mentioned gas concentration includes the concentration of combustible gases, such as carbon monoxide, hydrogen, oxygen, natural gas, methane, ethane, acetylene, ethanol, propane, propylene, butylene, methyl ether, vinyl chloride, liquefied petroleum gas, isobutylene, etc. , this application is not limited. The hazards of flammable gases are explained in detail below. The uniform mixture of flammable gases and combustible gases can cause explosions or combustion under extreme conditions. The combustion-supporting gas may be air, oxygen or other combustion-supporting gases. The explosion limit generally mentioned refers to the concentration limit of flammable gas in the air. The minimum content of flammable gas that can cause an explosion is called the lower explosion limit; the highest concentration is called the upper explosion limit. The components of the mixed system are different, and the explosion limits are also different. For the same mixing system, the explosion limit can change due to the initial temperature, system pressure, inert medium content, mixing system existing space and wall material, and ignition energy. The general rule is: as the original temperature of the mixing system increases, the explosion limit range increases, that is, the lower limit decreases and the upper limit increases. Because the temperature of the system increases, the intramolecular energy increases, making the originally non-combustible mixture become a flammable and explosive system. As the system pressure increases, the explosion limit range also expands. This is because the increase in system pressure brings the distance between molecules closer and increases the probability of collision, making the combustion reaction easier to proceed. As the pressure decreases, the explosion limit range shrinks; when the pressure drops to a certain value, its upper limit coincides with the lower limit, and the corresponding pressure at this time is called the critical pressure of the mixed system. When the pressure drops below the critical pressure, the system will not become an explosive system (some gases have abnormal phenomena). In this regard, exhaust fans can effectively reduce gas concentration and air pressure through exhaust air, thereby reducing risks.

In a possible example, step S502 includes the following steps B2-B4, where:

B2: The temperature measured at the n+1th time minus the temperature measured at the nth time is the temperature increase.

B3: The smoke concentration measured at the n+1th time minus the smoke concentration measured at the nth time is the smoke concentration increase value.

B4: The gas concentration measured at the n+1th time minus the gas concentration measured at the nth time is the gas concentration increase value.

For example, within 5 minutes, the temperature measured at the third time minus the temperature measured at the second time is the temperature increase value, and the smoke concentration measured at the third time minus the smoke concentration measured at the second time is the smoke concentration increase value. , the gas concentration measured at the third time minus the gas concentration measured at the second time is the gas concentration increment.

S503: Generate an exhaust fan control scheme based on the abnormal situation and the simulation model. The exhaust fan control scheme includes: the position of the activated exhaust fan, the number of activated exhaust fans, and the rotation speed of each exhaust fan.

Implementing an exhaust fan control scheme requires ensuring that the exhaust

The fan control scheme ensures that the total exhaust air volume per minute is not less than the volume of the energy storage container. The specific method is to mobilize multiple exhaust fans to work synchronously according to the formulation of the exhaust fan control scheme. There is a situation where the smoke concentration is high or the distance is high. The exhaust fan with a higher temperature works at the maximum speed (for example, it is best to preset the fan speed to 3000 rpm), and the other fan speeds can be set to a lower speed (such as 1500 rpm or 2000 rpm).

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

C1: When at least one of the following conditions occurs: the temperature increase value is within the first preset range, the smoke concentration increase value is within the second preset range, and the gas concentration increase value is within the third preset range, Control the exhaust fan speed to the preset speed;

C2: When at least one of the following conditions occurs: the temperature increase value exceeds the first preset range, the smoke concentration increase value exceeds the second preset range, and the gas concentration increase value exceeds the third preset range, control The exhaust fan speed is the maximum speed;

C3: Upload the exhaust fan control scheme to the exhaust server. The exhaust server can interact with the terminal device, and the terminal device controls the exhaust fan via the exhaust server.

For example, when the temperature increase value is in the range of 5 degrees Celsius to 10 degrees Celsius, the smoke concentration increase value is in the range of 50 mg/cubic meter to 100 mg/cubic meter, and the gas concentration increase value is in the range of 50 ppm to 100 ppm. At least one item is to control the exhaust fan speed to 1500 rpm. When at least one of the temperature increase value is between 10 degrees Celsius and 50 degrees Celsius, the smoke concentration increase value is between 100 mg/cubic meter and 500 mg/cubic meter, and the gas concentration increase value is between 100 ppm and 500 ppm, control The exhaust fan speed is 5000 rpm. When at least one of the temperature increase value is between 50 degrees Celsius and 200 degrees Celsius, the smoke concentration increase value is between 500 mg/cubic meter and 2000 mg/cubic meter, and the gas concentration increase value is between 500ppm and 2000ppm, control The exhaust fan speed is 10,000 rpm. The preset rotation speed can be adjusted according to the situation, when at least one of the temperature increase value exceeds 200 degrees Celsius, the smoke concentration increase value exceeds 2000 mg/cubic meter, and the gas concentration increase value exceeds 2000 ppm. , control the exhaust fan to exhaust air at the maximum 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, according to the temperature increase value A, the theoretical exhaust fan speed is 1000 rpm, according to the smoke concentration increase value B. The theoretical exhaust fan speed is 2000 rpm. According to the gas concentration increase value C, the exhaust fan speed is theoretically 3000 rpm. At this time, the selection is based on the maximum exhaust fan speed, that is, the exhaust fan speed is controlled to 3000 rpm.

For example, the exhaust fan speed refers to the number of times the fan blades rotate per minute. The speed of the exhaust fan can be controlled by controlling the working voltage and speed gears of the motor. When the fan structure is fixed, the speed of the DC fan (that is, a fan using DC power) changes synchronously with the change of the working voltage. For example, set the exhaust fan speed to 3000 rpm as level 1, set the exhaust fan speed to 8000 rpm as level 2, and set the exhaust fan speed to 15000 rpm as level 3. The exhaust fan speed can be adjusted according to different environmental conditions.

In a possible example, generating an exhaust fan control scheme based on the abnormal situation and the simulation model includes the following steps:

Input the abnormal situation into the simulation model, so that the simulation model simulates the abnormal situation occurring inside the energy storage container;

Use the simulation module to simulate starting the exhaust fan to obtain simulation results;

The position of the activated exhaust fans, the number of activated exhaust fans and the rotation speed of each exhaust fan are determined based on the simulation results.

In the embodiments provided in this application, the geometric parameters of the energy storage container, the geometric parameters of the battery clusters distributed in the energy storage container, the geometric parameters of the battery clusters, the electrochemical parameters and the thermal parameters are obtained. According to the electrochemical parameters of the battery, an electrochemical model of the battery to be modeled is established; wherein the electrochemical model includes a charge conservation sub-model, a mass conservation sub-model, an electrode kinetics sub-model, and an energy conservation sub-model; according to the thermal parameters of the battery, Establish a thermal model of the battery to be modeled; couple the electrochemical model and the thermal model through a three-dimensional model to form a simulation model, in which the heat generation rate output by the electrochemical model is input to the thermal model to simulate the electrochemical process. Generate heat to change the temperature of the battery; the temperature output by the thermal model is input to the electrochemical model to simulate the physical quantities that changes in temperature affect in the electrochemical process; wherein the electrochemical model calculates the heat generation rate of the battery, and then calculates the heat generation rate The rate is the heat source of the thermal model, and the internal temperature field of the battery is calculated; the temperature output by the thermal model of the electrochemical model adjusts the electrochemical parameters to realize the coupling of the electrochemical model and the thermal model.

At present, the simulation model can be established by PyroSim software. In PyroSim, the parameters of the exhaust fan can be imported to simulate the situation where the energy storage container starts the exhaust fan to cool down the battery cluster.

In the embodiment provided by this application, after the abnormal situation is input into the simulation model, the position of turning on the exhaust fan can be adjusted for simulation, and the simulation results of turning on the fan at different positions can be obtained. You can adjust the number of turned-on exhaust fans to obtain simulation results with different numbers of turned-on fans. You can adjust the speed of the turned-on exhaust fan to obtain simulation results of different speeds of the turned-on exhaust fan.

The simulation result may be at least one of the simulated increased value of temperature of the battery cluster, the simulated increased value of smoke concentration, and the simulated increased value of the first gas concentration.

When determining the exhaust fan control scheme, it is assumed that when the exhaust fan at position a is turned on, the abnormal situation of the battery cluster is improved best compared with turning on the fans at other positions. Position a can be determined to be the best position to turn on the exhaust fan.

Assuming that when n exhaust fans are turned on, the abnormal situation of the battery cluster is improved best compared with the number of fans turned on. It can be determined that turning on n exhaust fans is the optimal number of fans to turn on.

Assuming that the rotation speed of each exhaust fan turned on is ω, compared with other rotation speeds of the exhaust fan, the abnormal situation of the battery cluster is improved the best. It can be determined that the exhaust fan opening speed ω is the optimal rotation speed.

In a possible example, the simulation module is used to simulate starting the exhaust fan to obtain simulation results, including:

Use the simulation module to simulate starting the fan of the battery cluster at the location of the energy storage container where the abnormal situation occurs;

Taking the location of the battery cluster where the abnormality occurs in the energy storage container as the center position, increase the number of exhaust fans that are turned on from near to far;

Gradually increase the speed of the turned-on exhaust fan;

The simulation model is used to simulate the parameters of the battery cluster when the abnormal situation occurs when the exhaust fan is turned on at different positions, quantities, and rotation speeds. The parameters include the temperature simulation increased value and smoke concentration simulation of the battery cluster where the abnormal situation occurs. At least one of an increased value and an increased value of the first gas simulation concentration.

S504: When it is detected that some or all of the battery clusters in the energy storage container have thermal runaway, control all the exhaust fans in the area of the battery clusters where thermal runaway occurs to rotate at the maximum speed, and control the wind of the exhaust fan from a low temperature areas blow toward areas with higher temperatures.

For example, according to the exhaust fan control scheme, when it is detected that the battery cluster is thermally runaway, all exhaust fans in the battery cluster area are controlled to rotate at 10,000 rpm, and the wind of the exhaust fan is controlled to flow from the area with a low temperature. Blowing to areas with high temperatures, at this time, thermal runaway is controlled as much as possible in the area where it occurs, reducing the possibility of thermal runaway spreading to other areas inside the energy storage container.

S505: When it is detected that the abnormal situation occurs in part or all of the battery clusters in the energy storage container, the internal area of the energy storage container is divided into the first internal area according to the distance from the entrance, from nearest to far. area, a second inner area and a third inner area. When the thermal runaway is located in the third inner area, the exhaust fan speed of the third inner area is controlled to be the maximum speed, and the exhaust fan speed of the first inner area is controlled to be The minimum rotation speed and the exhaust fan rotation speed of the second internal area are between the maximum rotation speed and the minimum rotation speed. The exhaust fan rotation speed and the number of exhaust fans are calculated based on the total exhaust air volume per second being not less than the internal volume of the energy storage container.

For example, according to the exhaust fan control scheme, when it is detected that the abnormal situation occurs in part or all of the battery clusters in the energy storage container, the internal area of the energy storage container is adjusted according to the distance from the entrance. It is divided into a first internal area, a second internal area and a third internal area from near to far. When the thermal runaway is located in the third internal area, the exhaust fan speed of the third internal area is controlled to be 10,000 rpm, and the exhaust fan speed of the first internal area is controlled to 10,000 rpm. The exhaust fan speed is 1000 rpm, and the exhaust fan speed in the second internal area is 3000 rpm. The exhaust fan speed and number of exhaust fans are calculated based on the fact that the total exhaust volume per second is not less than the internal volume of the energy storage container.

For example, in the process of implementing the exhaust fan control scheme, it is always ensured that the exhaust fan control scheme ensures that the total exhaust air volume per second is not less than the volume of the energy storage container. Specifically, multiple exhaust fans are controlled according to the exhaust fan control scheme. It is formulated to work synchronously so that the exhaust fans in areas with the highest smoke concentration, highest temperature or highest gas concentration work at the maximum speed (for example, the preset fan speed is 10,000 rpm), and other fans have a speed of 2,000 rpm.

S506: When it is detected that the abnormal situation occurs in part or all of the battery clusters in the energy storage container, control the wind of the exhaust fans in the three areas to blow to the area where the abnormal situation occurs.

For example, according to the exhaust fan control scheme, when an abnormal smoke concentration is detected in the second internal area of the battery cluster, the wind from the exhaust fans in the first internal area, the second internal area, and the third internal area are all blown. To the second internal area, thereby reducing the spread of the smoke concentration and reducing the impact on other internal areas.

It should be noted that after the fire host completes the operation of the exhaust fan control scheme, it will send the exhaust fan control scheme and on-site processed video to the manager's electronic terminal, and the manager can view the details through the electronic terminal.

In a possible example, when the selected exhaust fan speeds are different according to the temperature increase value range, the smoke concentration increase value range, and the gas concentration increase value range, the processing module 602 determines the maximum fan speed according to the selected exhaust fan speed. Choose according to the situation.
