[0029] Embodiment 1

[0030] Figure 1 This is a flow chart of the electrochemical energy storage system safety control method provided according to the first embodiment of the present invention. This embodiment is applicable to the situation of safety control of the electrochemical energy storage system. The method can be executed by the electrochemical energy storage system safety control device. The electrochemical energy storage system safety control device can be implemented in the form of hardware and / or software. The electrochemical energy storage system safety control device can be configured in a device. For example, the device can be a background server or other device with communication and computing capabilities. Figure 1 As shown, the method includes:

[0031] S110, monitoring the state of the target battery in the electrochemical energy storage system to obtain monitoring results; wherein the electrochemical energy storage system includes various battery compartments; the battery compartments include various battery clusters; the battery clusters include various battery packs.

[0032] In this solution, the electrochemical energy storage system is composed of various battery compartments, and also includes fire alarm control devices for energy storage power stations, fire detection devices for energy storage power stations, special nozzles for battery boxes, fine water mist nozzles, cluster-level solenoid valves, etc. Among them, the battery compartment is composed of various battery clusters; the battery cluster is composed of various battery packs (battery packs), and the battery pack generally refers to a combined lithium-ion battery pack, including packaging, encapsulation and assembly.

[0033] Among them, the fire status of electrochemical energy storage systems is generally divided into three states, including early warning, fire prevention and isolation, and fire extinguishing. Early warning is particularly important. By setting up detection equipment to warn of abnormal battery status in the electrochemical energy storage system, the abnormal situation can be notified to the on-site personnel as quickly as possible, and effective fire isolation and other means can be used to reduce the harm and damage of the accident.

[0034] In this embodiment, the monitoring results include normal state and abnormal state. The abnormal state includes abnormal temperature, abnormal current, abnormal voltage and smoke detection of the battery.

[0035] Specifically, the state of the target battery in the electrochemical energy storage system can be monitored in real time using a detection device, which can be a sensor, a smoke sensor, or the like.

[0036] Optionally, the state of the target battery in the electrochemical energy storage system is monitored to obtain monitoring results, including:

[0037] Based on the pre-installed smoke detection equipment, the target battery in the electrochemical energy storage system is monitored to obtain the monitoring result; wherein the smoke detection equipment is installed on each battery pack.

[0038] In this program, Figure 2 is a top view of the battery compartment provided in the first embodiment of the present application, such as Figure 2 As shown, the circle in the battery compartment is a smoke detection device. When the smoke detection device detects smoke in the target battery in the electrochemical energy storage system, it can transmit an alarm signal to the alarm controller, which will send an audible and visual alarm. The alarm controller will transmit the alarm of the compartment to the on-duty personnel in the control room. In addition, the liquid cooling host system will continuously cool down the running batteries in the compartment and strengthen the cooling control of batteries with excessively high temperatures.

[0039] By detecting the abnormal status of the target battery, an alarm can be quickly and timely generated so that the faulty equipment can be fire-isolated as soon as possible.

[0040] Optionally, monitoring the state of a target battery in the electrochemical energy storage system to obtain a monitoring result also includes:

[0041] The temperature, current and voltage of the target battery in the electrochemical energy storage system are monitored based on the pre-installed sensors to obtain the monitoring results.

[0042] In this embodiment, the sensor may be a temperature sensor, a current sensor, or a voltage sensor. Figure 3 is a side view of the battery compartment provided in the first embodiment of the present application, such as Figure 3As shown, sensors are installed in the control box of the battery compartment to collect temperature, current, and voltage information of each battery pack. Alarms are issued for abnormal current and voltage, and for excessive battery temperature. In addition, the battery coolant temperature and electrolyte leakage are continuously monitored, and alarms are issued for abnormal current and excessive temperature. Among them, the temperature sensor adopts the super-sensing temperature sensor of Gote Electronics. By adopting chip-level plastic packaging technology, internal pin redundancy design, and unique metal-metal conduction method, the temperature of each battery cell and the rapid change of temperature can be detected more accurately. Through the welding and method of chips, nickel sheets and aluminum bars, full metal conduction is achieved, which increases the temperature response by 3 times and improves the sensitivity and accuracy of temperature perception. Thereby, rapid detection of battery temperature is achieved to achieve the goal of early identification of risks and safety warnings.

[0043] Among them, Figure 3 As shown, the battery compartment is also equipped with a maintenance switch, which can be quickly and conveniently opened manually. There is a fire hose interface at the bottom, which can be connected to sprinkler water for fire linkage fire extinguishing.

[0044] By detecting the abnormal status of the target battery, an alarm can be quickly and timely generated so that the faulty equipment can be fire-isolated as soon as possible.

[0045] S120, determining a safety control area corresponding to the monitoring result; wherein the safety control area is set according to the level to which the battery belongs.

[0046] Among them, the levels include battery pack level (pack level), battery cluster level, battery compartment level and firewall level.

[0047] In this solution, the safety control area refers to the area for safety control of the electrochemical energy storage system, which can be set according to the level of the battery. For example, when the battery level is the battery pack level, the safety control area is the space area to which the battery pack belongs; when the battery level is the battery cluster level, the safety control area is the space area to which the battery cluster belongs.

[0048] Optionally, the security control area includes a first security control area, a second security control area, a third security control area and a fourth security control area; wherein, the first safety control area is determined by the spatial area to which the battery pack belongs; the second safety control area is determined by the spatial area to which the battery cluster belongs; the third safety control area is determined by the spatial area to which the battery compartment belongs; the fourth safety control area is determined by the spatial area to which the firewall belongs; and the spatial area to which the firewall belongs is composed of at least two spatial areas to which battery compartments belong.

[0049] In this solution, the fire walls of energy storage power stations include: Brick walls. The internal walls of energy storage power stations are often isolated with brick walls. The advantages of this kind of fire wall are good air permeability and flame retardant effect. Steel plate walls are reinforced with steel plates to withstand high temperatures and fire, and are not easy to generate sparks, which slows down the spread of fire. Glass walls can effectively resist heat radiation, but when installed inside the power station, care should be taken not to have cracks or other problems.

[0050] In this solution, the security control area can be divided according to the levels of battery packs, battery clusters, battery compartments and firewalls. Figure 4 is a hierarchical schematic diagram provided in Example 1 of the present application, such as Figure 4 As shown, safety management and control considers fire prevention and isolation at different levels. The volume of battery cells and battery packs is still relatively small. When an abnormal situation occurs, they are isolated and removed to prevent the spread of fire and ensure minimum losses. Battery cluster-level fire prevention mainly relies on inter-cluster fire isolation. After the faulty battery cluster is powered off and isolated, fire barriers are installed between battery clusters to prevent the spread of fire while delaying heat conduction and reducing the impact on adjacent battery clusters. Battery compartment-level fire prevention mainly relies on the fire extinguishing and isolation functions of the compartment. Fire walls are used to prevent the compartment from burning and spreading to other compartments, so as to achieve the effect of isolation within the area and minimize losses.

[0051] Furthermore, Figure 5 This is a schematic diagram of a firewall provided in Example 1 of the present application. Figure 5 As shown, the thick line is the design of the firewall, which divides the battery compartment in the entire electrochemical energy storage system into multiple areas, and the firewall effectively blocks the spread of fire. In addition, fire water tanks and fire pump stations are configured in the area to extinguish fires in the fire area.

[0052] Abnormal and fire-causing equipment isolation can control the current fire to the minimum loss according to the levels of battery packs, battery clusters, battery compartments, and firewalls; while dealing with the fire point, the firewall can be effectively used to control and isolate the fire source to prevent the spread and spread of the fire; multiple firewalls can effectively achieve fire isolation without affecting the energy storage in the adjacent areas, making subsequent reconstruction more convenient and facilitating on-site operation and maintenance; modular energy storage cell packs are easy and efficient to disassemble and install, which is conducive to the establishment of fire barrier measures; the energy storage battery pack-level fire barrier effect is good, which can effectively prevent the spread of fire , and subsequent replacement of battery packs is more convenient; the energy storage battery cluster has an outstanding protective barrier effect, which effectively avoids heat conduction between battery clusters and prevents the spread of fire. The battery cluster fire extinguishing device can be opened separately to achieve firewall isolation at the battery cluster level; the energy storage battery compartment has complete fire isolation facilities, and the fire protection system can realize linkage function, and cooperate with the water system fire protection outside the personnel to effectively avoid the spread of fire and control the disaster; the energy storage area firewall divides the space of the entire energy storage system. When the fire is uncontrollable, the fire is regionally blocked to prevent the fire from spreading comprehensively and maximize the safety of the remaining areas.

[0053] Optionally, determining a security control area corresponding to the monitoring result includes:

[0054] Obtain the level to which the target battery in the electrochemical energy storage system belongs;

[0055] If the monitoring result of the target battery is in an abnormal state, a safety control area corresponding to the monitoring result is determined according to the level to which the target battery belongs.

[0056] In this solution, when the state of the target battery is monitored to be abnormal, the level to which the target battery belongs is obtained, and the spatial area to which the level belongs is used as a security control area.

[0057] Safety management and control is achieved through the four-layer protection of battery packs, battery clusters, battery compartments, and firewalls. After a fire occurs, effective isolation measures can be taken in a timely manner to prevent the spread and expansion of the fire, facilitating daily operation and maintenance.

[0058] S130: Perform safety control on the electrochemical energy storage system according to the safety control area.

[0059] Specifically, an alarm can be sounded for the electrochemical energy storage system in the safety control area and fire isolation operations can be performed.

[0060] In this program, Figure 6 This is a schematic diagram of the fire linkage wiring provided in Example 1 of the present application, such as Figure 6As shown, when an abnormal battery state is detected, the BMS (Battery Management System) will cut off the battery in the faulty state, execute the interlocking logic, activate the fire-fighting equipment, activate the sound and light alarm, and link the smoke and exhaust, and transmit the alarm of the cabin to the on-duty personnel in the control room.

[0061] Furthermore, the fire detection system of BMS is optimized, fault diagnosis based on threshold is optimized, and thresholds for differential pressure alarm, abnormal temperature alarm, abnormal gas monitoring, etc. are set to achieve the expansion and accuracy of BMS functions; the fault warning logic of the battery model is optimized, and early warning is carried out based on statistical learning and algorithms; the battery warning system is optimized. The energy storage BMS presets fire response plans, and issues corresponding disposal plan commands and operation reminders for different levels of fire, so that on-site personnel can perform fire extinguishing work more quickly.

[0062] Optionally, performing safety control on the electrochemical energy storage system according to the safety control area includes:

[0063] If the safety control area is the first safety control area, safety control is performed on the battery pack in the first safety control area;

[0064] If the safety control area is a second safety control area, performing safety control on the battery cluster in the second safety control area;

[0065] If the safety control area is the third safety control area, safety control is performed on the battery compartment in the third safety control area;

[0066] If the safety control area is the fourth safety control area, safety control is performed on at least two battery compartments in the fourth safety control area.

[0067] In this solution, after a fire alarm occurs in the energy storage safety management system, fire extinguishing measures for different situations are adopted. If the battery cell is abnormal, the battery pack will be used as an isolation and protection measure. When the pack is burning, the pack will be fireproofed and the fire extinguishing device will spray gas fire extinguishing agent (such as heptafluoropropane and perfluorohexanone) to extinguish the fire. When the entire battery compartment has been burned, the fire will be extinguished by relying on the cabin fire protection system, and hand-push fire extinguishers and water fire fighting will be used to isolate other cabins and cool down the fire area. If the fire has spread to multiple battery compartments, water fire fighting will be used to continuously spray the affected area, and cement fire walls will be used to achieve fire isolation to prevent the burning of larger areas. Multiple fire prevention measures effectively achieve fire isolation without affecting the energy storage in the adjacent areas, making subsequent reconstruction more convenient and facilitating on-site operation and maintenance.

[0068] In this embodiment, the modular energy storage cell pack is convenient and efficient to disassemble and install, which is conducive to the establishment of fire barrier measures. The energy storage battery pack has a good fire barrier effect, which can effectively prevent the spread of fire. Fire can be extinguished with portable heptafluoropropane and perfluorohexanone fire extinguishers, and the subsequent replacement of battery packs is more convenient. The protective barrier effect of the energy storage battery cluster is outstanding, which effectively prevents heat conduction between battery clusters and prevents the spread of fire. The battery cluster fire extinguishing device can be opened separately to achieve firewall isolation at the battery cluster level. The energy storage battery cabin has complete fire isolation facilities, and the fire protection system can realize linkage function. In conjunction with the water system fire protection outside the personnel, it can effectively prevent the spread of fire and control the disaster. The liquid cooling host system continuously cools the running batteries in the cabin and strengthens the cooling control of batteries with too high temperature. The energy storage area firewall divides the entire energy storage system into spaces. When the fire is uncontrollable, the fire is blocked in the area to prevent the fire from spreading comprehensively and maximize the safety of the remaining areas.

[0069] Optionally, performing safety control on the electrochemical energy storage system according to the safety control area further includes:

[0070] Determine the door opening angle, and control the battery compartment to perform the door opening operation according to the door opening angle.

[0071] In this embodiment, the door opening angle can be set according to the fire protection requirements of the battery compartment. For example, the door opening angle can be set to 135 degrees.

[0072] Specifically, Figure 2 As shown, for the door opening processing scenario, the door opening angle is increased by 135° to provide personnel with more operating space.

[0073] By setting a larger door opening angle, it is easier for workers to carry out fire isolation and reduce the hazards and damage of accidents.

[0074] In this solution, alarms can be distinguished by different colors. Generally, it is a yellow alarm, which automatically links the liquid cooling temperature control, cabin exhaust cooling, etc.; the important type is a red alarm, which executes the fire linkage alarm, and the smoke sensor triggers the exhaust, spray cooling and other operations; if the current and voltage are abnormal, the PACK, battery cluster, or battery compartment will be controlled and cut off. The execution operation can be refined into three categories: computer program interlocking logic operation, operation and maintenance personnel's computer (control background) operation, and operation and maintenance personnel's on-site emergency operation.

[0075] Furthermore, for the management and control operation logic of the electrochemical energy storage system, the management and control logic is iteratively optimized based on the information collected from daily interactions (inspection records, correction of abnormal monitoring data, regular execution of capacity balancing of energy storage, etc.; environmental changes such as temperature and humidity throughout the year). For example, if the temperature is higher in a fixed season, the temperature control system will be turned on regularly; if the humidity is higher, ventilation and dehumidification will be turned on; if the battery cell data is abnormal (signal is taken every second, frame loss, data drift, mutation, etc.), it can analyze and determine whether it is an accidental abnormality of the BMS or damage to the detection component, and give a processing push signal to achieve intelligent management and control.

[0076] The technical solution of the embodiment of the present invention monitors the state of the target battery in the electrochemical energy storage system to obtain the monitoring results, then determines the safety control area corresponding to the monitoring results, and performs safety control on the electrochemical energy storage system based on the safety control area. By executing this technical solution, an abnormal state is detected and an alarm can be quickly and timely generated so that the faulty equipment can be isolated as soon as possible; the abnormal and fire-causing equipment can be isolated to control the current fire to the minimum loss according to the levels of battery packs, battery clusters, battery compartments, and firewalls; while the fire point is being dealt with, the firewall can be effectively used to control and isolate the fire source to avoid the spread and spread of the fire; multiple firewalls can effectively achieve fire isolation without affecting the energy storage in the adjacent areas, making subsequent reconstruction more convenient and facilitating on-site operation and maintenance; modular energy storage cell packs are easy and efficient to disassemble and install, which is conducive to the establishment of fire barrier measures; the energy storage battery pack has a good level of fire barrier effect, which can effectively prevent the spread of fire, and subsequent replacement of batteries p ack is more convenient; the protective barrier effect of the energy storage battery cluster is outstanding, which can effectively avoid heat conduction between battery clusters and prevent the spread of fire. The battery cluster fire extinguishing device can be opened separately to achieve firewall isolation at the battery cluster level; the fire isolation facilities of the energy storage battery compartment are complete, and the fire protection system can realize linkage function, cooperating with the water system fire protection outside the personnel, which can effectively prevent the spread of fire and control the disaster; the energy storage regional firewall divides the space of the entire energy storage system. When the fire is uncontrollable, the fire is regionally blocked to prevent the fire from spreading comprehensively and maximize the safety of the remaining areas; the energy storage BMS presets fire response plans, and issues corresponding disposal plan commands and operation reminders for different levels of fire, so that on-site personnel can perform fire extinguishing work more quickly.
