[0041] Determining the first primary system and the first standby systems;

[0042] When the first primary system and the first standby systems are confirmed to be correct, the first primary system determines the first control strategy for controlling the energy storage valve according to the thermal runaway risk condition.

[0043] Through the above implementation manners, redundant configuration of the energy storage control system can be realized, and the stability of the fire protection linkage control system of the energy storage valve can be improved.

Thus, when the energy storage valve has a thermal runaway risk, the control strategy can be executed through the energy storage valve control system to control the energy storage valve, and the fire control system can be controlled to execute the fire protection strategy and conduct fire protection on the energy storage valve, that is, the linkage control between the energy storage valve control system and the fire control system can be realized, thereby reducing the risk of fire and explosion accidents of the energy storage valve.

[0048] In some embodiments, when the thermal runaway risk status indicates that the energy storage valve has no thermal runaway risk, the second control strategy is to control the energy storage valve to operate normally, and the second fire protection strategy is not to conduct fire protection on the energy storage valve;

[0052] Through the above implementation methods, the accuracy of the energy storage valve fire control can be improved.

[0053] In some embodiments, the method further includes:

[0054] When the time for the fire control system to conduct fire protection on the energy storage valve is greater than or equal to the first duration and the thermal runaway risk status still indicates that the energy storage valve has a thermal runaway risk, a warning instruction is sent to the energy storage control system;

[0070] Hereinafter, embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and thus are only examples and should not be used to limit the protection scope of the present application.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above accompanying drawings are intended to cover non-exclusive inclusion.

[0072] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality" is more than two, unless otherwise specifically defined.

[0073] Referring to "embodiments" herein means that specific features, structures or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0074] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, X and / or Y may represent: X exists alone, X and Y exist simultaneously, and Y exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0075] In an embodiment of the present application, the energy storage valve includes at least one energy storage sub-module, and each energy storage sub-module includes at least one battery module and at least one power module, and the battery module and the power module are connected to each other. Each battery module includes at least one battery. The batteries are placed in an electric cabinet, and each electric cabinet contains at least one battery. As an example, taking the battery module as a unit, each electric cabinet contains one or more battery modules. As another example, taking the electric cabinet as a unit, each battery module is dispersed and placed in one or more electric cabinets. For example, the electric cabinet corresponds to an electric cabinet control and protection system, the battery module corresponds to a battery module control and protection system, the power module corresponds to a power module control and protection system, and the energy storage valve corresponds to an energy storage valve control and protection system. For another example, the battery module control and protection system may include the electric cabinet control and protection system.

[0076] In order to reduce the risk of fire and explosion accidents of the energy storage valve, the related art provides a fire protection system applied to the energy storage valve. As an example, this fire protection system is used to extinguish the fire when the energy storage valve catches fire, for example, by spraying fire extinguishing agent. As another example, this fire protection system is used to reduce the risk of fire and explosion accidents of the energy storage valve, for example, by filling nitrogen into the environment where the energy storage valve is located, so that the energy storage valve is in an inert gas environment to reduce the combustion risk, thereby reducing the risk of fire and explosion accidents of the energy storage valve.

[0077] However, the fire protection system provided by the above related art monitors the fire risk of the battery independently and takes corresponding fire extinguishing measures. That is to say, the system provided by the related art for protecting the energy storage valve is an independent system, which is not linked with other systems and cannot respond to the alarms of other systems, so that the risk of fire and explosion accidents of the energy storage valve is still relatively high.

[0078] In view of this, an embodiment of the present application provides an energy storage valve fire protection linkage control system, including: at least one energy storage control system and at least one fire protection control system, and each energy storage control system is communicatively connected to at least one fire protection control system.

[0079] The energy storage control system is communicatively connected to the energy storage valve, can obtain the thermal runaway risk status of the energy storage valve, and determine a control strategy for controlling the energy storage valve according to the thermal runaway risk status of the energy storage valve. For example, when there is a thermal runaway risk in the first battery in the energy storage valve, the first battery can be controlled to cut off power and withdraw. The energy storage control system can also determine a fire protection strategy for the energy storage valve according to the thermal runaway risk status of the energy storage valve. For example, when there is a thermal runaway risk in the first battery in the energy storage valve, inert gas is filled around the first battery; the energy storage control system can send this fire protection strategy to the fire protection control system communicatively connected to it, and control the fire protection system to execute this fire protection strategy through the fire protection control system.

[0080] Among them, the energy storage control system may include at least one of an energy storage valve control system, a battery management system, and a power module control system. The energy storage valve control system may be, for example, the above-mentioned energy storage valve control and protection system or other systems capable of controlling the energy storage valve; the battery management system may be, for example, the above-mentioned battery module control and protection system or other systems capable of controlling the battery; the power module control system may be, for example, the above-mentioned power module control and protection system or other systems capable of controlling the power module. For ease of understanding, in the embodiments of the present application, the energy storage valve control and protection system, the battery module control and protection system, and the power module control and protection system are taken as examples for illustrative description.

[0081] The fire control system may be communicatively connected to the fire protection system. It may control the fire protection system to execute the fire protection strategy based on the fire protection strategy obtained from the energy storage control system to perform fire protection on the energy storage valve. The fire control system may also obtain the thermal runaway risk status of the energy storage valve, determine the fire protection strategy for the energy storage valve according to the thermal runaway risk status of the energy storage valve, and then control the fire protection system to execute the fire protection strategy to perform fire protection on the energy storage valve. For example, in the case where the first battery in the energy storage valve has a thermal runaway risk, an inert gas may be filled around the first battery. Among them, the above-mentioned first battery may be any battery in the energy storage valve. For ease of understanding, in the subsequent embodiments of the present application, the thermal runaway risk control for the first battery in the energy storage valve will be mainly taken as an example for illustrative description.

[0082] Among them, the fire protection system may include an inert gas system and / or other fire protection systems, such as a fire extinguishing system; correspondingly, the fire control system may include an inert gas control system and / or other fire control systems such as a fire extinguishing control system. The fire protection system and the fire control system may be independent systems or integrated in the same system. For example, the inert gas system and the inert gas control system may be integrated in an inert gas protection system. For ease of description, in the embodiments of the present application, the inert gas protection system is taken as an example for illustrative description.

[0083] In the energy storage valve fire linkage control system provided by the embodiments of the present application, the energy storage control system is communicatively connected to the energy storage valve, so as to obtain the thermal runaway risk status of the energy storage valve, and then determine the control strategy for the energy storage valve accordingly, so as to reduce the thermal runaway risk inside the energy storage valve (for example, by controlling the first battery to cut off power and withdraw to reduce the risk of thermal runaway diffusion inside); the fire control system is communicatively connected to the fire protection system, so as to perform fire protection on the energy storage valve through the fire protection system to reduce the thermal runaway risk outside the energy storage valve (for example, by filling inert gas to reduce the external thermal runaway risks such as fire and explosion). And the energy storage control system and the fire control system are communicatively connected, so that linkage control can be realized, enabling the energy storage valve with a thermal runaway risk to be effectively controlled in a timely manner, and further enabling the energy storage valve to operate reliably and stably.

[0084] The battery in the embodiments of the present application may be a secondary battery. The battery in the embodiments of the present application can be used in electrical devices that use the battery as a power source or various energy storage systems that use the battery as an energy storage element. The electrical device may be, but is not limited to, a mobile phone, a tablet computer, a laptop computer, an electric toy, an electric tool, a battery car, an electric vehicle, a ship, a spacecraft, and the like. The energy storage system includes various energy storage valves, such as a high-voltage direct-connected energy storage valve.

[0085] To illustrate the technical solutions described in the present application, the following will be described through specific embodiments.

[0086] Please refer to Figure 1 , some embodiments of the present application provide an energy storage valve fire linkage control system, including: at least one energy storage valve control and protection system and at least one inert gas protection system, and each energy storage valve control and protection system is communicatively connected to at least one inert gas protection system.

[0087] As Figure 1 shown, n is an integer equal to or greater than 1. As an example, the communication connection can be achieved through optical fibers or other communication cables for data interaction.

[0088] The energy storage valve control and protection system is used to obtain the thermal runaway risk status of the first battery, and determine a control strategy for controlling the first battery according to the thermal runaway risk status of the first battery. For example, the control strategy may be to control the first battery to power off and exit when there is a thermal runaway risk in the first battery. In this way, the risk of thermal runaway diffusion of the first battery can be reduced when there is a thermal runaway risk in the first battery. For example, the energy storage valve control and protection system can directly control the first battery to power off and exit, or can control the first battery to power off and exit by triggering the battery module control and protection system.

[0089] The energy storage valve control and protection system is also used to determine a fire protection strategy for the first battery according to the thermal runaway risk status of the first battery. The energy storage valve control and protection system can send the fire protection strategy to the inert gas protection system, and the first battery is fire-protected through the inert gas protection system.

[0090] The inert gas protection system can extinguish a fire on the first battery according to the fire-fighting strategy obtained from the energy storage valve control protection system, or it can obtain the thermal runaway risk status of the first battery and determine the fire-fighting strategy for the first battery according to the thermal runaway risk status of the first battery. For example, the fire-fighting strategy can be to fill the area around the first battery with inert gas when there is a thermal runaway risk for the first battery. In this way, the risk of fire occurring in the first battery can be reduced when there is a fire risk for the first battery. For example, by filling the electrical cabinet to which the first battery belongs with inert gas, the concentration of combustible gas and the concentration of combustion-supporting gas in the electrical cabinet can be reduced, so as to reduce the risk of fire occurring in the first battery. For example, the inert gas protection system can start the inert gas replacement mode to output inert gas externally, so as to achieve filling the electrical cabinet to which the first battery belongs with inert gas.

[0091] Moreover, since each energy storage valve control protection system is communicatively connected to at least one inert gas protection system, the above-mentioned energy storage valve control protection system and inert gas protection system can share the information on whether there is a thermal runaway risk for the first battery, so that the energy storage valve control protection system and the inert gas protection system can simultaneously execute the corresponding protection measures according to the information on whether there is a thermal runaway risk for the first battery, so as to achieve the purpose of interlocking control.

[0092] The above-mentioned energy storage valve fire-fighting interlocking control system can, through the interlocking control between the energy storage valve control protection system and the inert gas protection system, enable the first battery with a thermal runaway risk to be effectively controlled and warned in a timely manner, so as to protect the energy storage valve and make the energy storage valve operate reliably and stably.

[0093] In the embodiment of the present application, the thermal runaway risk can be used to reflect the internal risk and / or external risk of the battery.

[0094] For example, the thermal runaway risk includes: the thermal runaway risk caused by the too high temperature of the battery. For example, the thermal runaway risk includes: the fire risk of easy combustion caused by the too high concentration of combustion-supporting gas (such as oxygen concentration) in the electrical cabinet to which the battery belongs, or the fire risk of easy combustion caused by the too high concentration of combustible gas (such as hydrogen concentration generated by the thermal runaway of the battery) in the electrical cabinet to which the battery belongs, or the fire risk of easy combustion caused by the too low concentration of inert gas (such as nitrogen when the inert gas is nitrogen) in the electrical cabinet to which the battery belongs.

[0095] Therefore, as an example, it is possible to determine whether a battery has a thermal runaway risk by detecting the temperature of the battery. For example, when the temperature of the battery is greater than or equal to the first temperature threshold, it indicates that the battery has a thermal runaway risk; otherwise, it indicates that the battery does not have a thermal runaway risk. As an example, it is possible to determine whether a battery has a thermal runaway risk by detecting the concentration of combustion-supporting gas, combustible gas, or inert gas in the electrical cabinet to which the battery belongs. For example, when the concentration of combustible gas is greater than or equal to the first concentration threshold, it indicates that the battery has a thermal runaway risk; otherwise, it indicates that the battery does not have a thermal runaway risk.

[0096] In the embodiments of the present application, the energy storage valve can control the protection system, the inert gas protection system, the power module control and protection system, the battery module control and protection system, or other systems to detect and determine whether a battery has a thermal runaway risk. The energy storage valve control and protection system can determine whether a battery has a thermal runaway risk by obtaining the detection and determination result.

[0097] For example, the battery module control and protection system can determine whether a battery has a thermal runaway risk by detecting the temperature of the battery and send the detection result to the energy storage valve control and protection system. For example, the inert gas protection system can determine whether a battery has a thermal runaway risk by detecting the gas concentration in the electrical cabinet to which the battery belongs and send the detection result to the energy storage valve control and protection system.

[0098] It can be understood that here mainly the example of whether a battery in the energy storage valve has a thermal runaway risk is used for illustration. In some embodiments, it is also possible to detect whether the power module has a thermal runaway risk such as excessive temperature rise. The energy storage valve control and protection system can also determine the thermal runaway risk status of the energy storage valve accordingly. The specific detection method is similar to that of the battery. For example, it is possible to detect the temperature and / or various gas concentrations of the power module, etc., which will not be elaborated here.

[0099] In some embodiments, it is also possible to use the entire energy storage sub-module as the detection object to detect whether the energy storage sub-module has a thermal runaway risk such as excessive temperature rise. The energy storage valve control and protection system can determine the thermal runaway risk status of the energy storage valve accordingly. The specific detection method can combine the relevant content of battery detection and power module detection, which will not be elaborated here.

[0100] The above-mentioned energy storage valve fire-fighting linkage control system can monitor the internal and external risks of the battery and, through the linkage control between the energy storage valve control and protection system and the inert gas protection system, enable the first battery with a thermal runaway risk to be effectively controlled and warned in a timely manner, thereby realizing the protection of the energy storage valve and enabling the energy storage valve to operate reliably and stably.

[0101] In some embodiments of the present application, the energy storage valve control and protection system is further configured to perform at least one of the following actions when the first battery has a thermal runaway risk:

[0102] Control the power-off and withdrawal of the electrical cabinet to which the first battery belongs, control the bypass of the energy storage sub-module to which the first battery belongs, control the locking of the energy storage valve, and control the power-off and withdrawal of all electrical cabinets included in the energy storage sub-module to which the first battery belongs.

[0103] For example, when it is determined that the first battery has a risk of thermal runaway, the battery module control and protection system can be triggered to control the power-off and withdrawal of the electrical cabinet to which the first battery belongs to protect the electrical cabinet in a timely manner. The power module control and protection system can also be triggered to control the bypass of the energy storage sub-module to which the first battery belongs, and the battery module control and protection system can be triggered to control the power-off and withdrawal of all electrical cabinets included in the energy storage sub-module, so that the energy storage sub-module to which the first battery belongs stops working, thereby reducing the risk of fire and explosion accidents of the energy storage valve.

[0104] In the embodiment of the present application, when it is determined that the first battery has a risk of thermal runaway, the energy storage valve control and protection system is further used to trigger the inert gas protection system to start the inert gas replacement mode. When the inert gas protection system starts the inert gas replacement mode, it is used to fill the electrical cabinet to which the first battery belongs with inert gas to increase the concentration of inert gas in the electrical cabinet, and reduce the concentration of combustible gas and combustion-supporting gas in the electrical cabinet, so as to reduce the combustion risk of the electrical cabinet, and further reduce the risk of fire and explosion accidents of the energy storage valve.

[0105] In some embodiments of the present application, if the energy storage valve does not have a risk of thermal runaway, the corresponding control strategy can be to control the normal operation of the energy storage valve, and the corresponding fire protection strategy can be not to perform fire protection on the energy storage valve.

[0106] In some embodiments of the present application, it is also possible to further determine the control strategy and fire protection strategy according to the level of the thermal runaway risk when the energy storage valve has a risk of thermal runaway. For example, when the thermal runaway risk is at the first level, the corresponding control strategy is to control the normal operation of the energy storage valve, and the corresponding fire protection strategy is to perform fire protection on the energy storage valve (such as starting the inert gas replacement mode); when the thermal runaway risk is at the second level, the corresponding control strategy is to perform at least one of the above actions, and the corresponding fire protection strategy is to perform fire protection on the energy storage valve.

[0107] Among them, the severity of the risk at the second level is greater than that of the risk at the first level. For example, if the energy storage valve control and protection system does not detect a risk of thermal runaway of the first battery, and the inert gas protection system detects a risk of thermal runaway of the first battery, it can be considered that the thermal runaway risk is at the first level; if both the energy storage valve control and protection system and the inert gas protection system detect a risk of thermal runaway of the first battery, it can be considered that the thermal runaway risk is at the second level. The specific method for determining the level is not limited to this.

[0108] The above energy storage valve fire linkage control system can trigger the battery module control and protection system to cut off the power supply of the electrical cabinet to which the first battery belongs when there is a risk of thermal runaway of the first battery, so as to protect the electrical cabinet in time. It can also trigger the power module control and protection system to bypass the energy storage sub-module to which the first battery belongs, and trigger the battery module control and protection system to cut off the power supply of all electrical cabinets included in the energy storage sub-module, so that the energy storage sub-module to which the first battery belongs stops working, and can control the energy storage valve to lock, so as to reduce the risk of fire and explosion accidents of the energy storage valve.

[0109] In some embodiments of the present application, the energy storage valve fire linkage control system further includes a battery module control and protection system and / or a power module control and protection system.

[0110] The energy storage valve control and protection system can control the first battery to cut off the power supply through the battery module control and protection system; and / or, the energy storage valve control and protection system can control the energy storage sub-module to which the first battery belongs to bypass through the power module control and protection system. When there is a risk of thermal runaway of the first battery, the energy storage valve control and protection system can also control the power module corresponding to the first battery to disconnect from the battery module through the power module control and protection system.

[0111] In some embodiments of the present application, the energy storage valve control and protection system is communicatively connected to the power module control and protection system, and the power module control and protection system is communicatively connected to the battery module control and protection system; or, the energy storage valve control and protection system is communicatively connected to the power module control and protection system, and the energy storage valve control and protection system is communicatively connected to the battery module control and protection system.

[0112] In the embodiments of the present application, the battery module control and protection system can be communicatively connected to the power module control and protection system to realize communicative connection with the energy storage valve control and protection system, or can be directly communicatively connected to the energy storage valve control and protection system without passing through the power module control and protection system.

[0113] In some embodiments of the present application, the number of the energy storage valve control and protection systems and the inert gas protection systems is multiple, and each energy storage valve control and protection system is communicatively connected to multiple inert gas protection systems. For example, as Figure 1 shown, n>1.

[0114] After such setting, multiple energy storage valve control and protection systems can be backed up to each other, and multiple inert gas protection systems can be backed up to each other.

[0115] For example, any one of the multiple energy storage valve control and protection systems can be selected as the main system for use, and the other energy storage valve control and protection systems among the multiple energy storage valve control and protection systems can be used as backup systems but not put into use for the time being. It should be noted that any one of the energy storage valve control and protection systems can be manually or automatically switched to be used as the main system.

[0116] For example, any one of multiple inert gas protection systems can be selected as the primary system for use, and the other inert gas protection systems among the multiple inert gas protection systems can be used as standby systems but not put into use temporarily. It should be noted that any one of the inert gas protection systems can be manually or automatically switched to be used as the primary system.

[0117] In the above energy storage valve fire linkage control system, by setting the number of energy storage valve control protection systems and inert gas protection systems to be multiple, redundant configuration is achieved to improve the stability of the energy storage valve fire linkage control system.

[0118] Please refer to Figure 2 , taking the number of energy storage valve control protection systems and inert gas protection systems as 2 as an example. In some embodiments of the present application, the linkage control system further includes n power module control protection systems and n battery module control protection systems. The n battery module control protection systems are respectively communicatively connected to the n power module control protection systems. Each power module control protection system is connected to multiple energy storage valve control protection systems, and n is an integer greater than or equal to 1.

[0119] As an example of an application scenario of the embodiment of the present application, the battery module control protection system is used to be responsible for the control and protection of battery cells, battery packs, battery clusters, and battery stacks, and is also used to collect the temperature of each battery cell so as to determine whether the battery has thermal runaway according to the temperature of the battery cell.

[0120] As an example of an application scenario of the embodiment of the present application, the power module control protection system is used to be responsible for the locking and unlocking of the power module and the protection function of the power module, and is also used to be responsible for uploading the data collected by the battery module control protection system to the energy storage valve control protection system through this system. For example, the temperature of the battery cell collected by the battery module control protection system, and / or the determination result of whether the battery has thermal runaway, is uploaded to the energy storage valve control protection system through the power module control protection system.

[0121] As an example of an application scenario of an embodiment of the present application, the energy storage valve control and protection system is responsible for the start, stop, locking, unlocking, and warning strategies of the energy storage valve, and is also used to form a control strategy based on the obtained thermal runaway-related information to achieve the control and protection of the energy storage valve. For example, the thermal runaway-related information includes whether there is thermal runaway in the battery. For example, the control strategy includes that in the case of thermal runaway in the first battery, the energy storage valve control and protection system triggers the power module control and protection system to bypass the energy storage sub-module to which the first battery belongs, triggers the battery module control and protection system to cut off the power supply of all electrical cabinets included in the energy storage sub-module and withdraw, and triggers the inert gas protection system to start the inert gas replacement mode. For example, the warning strategy includes that in the case of thermal runaway in the first battery, the energy storage valve control and protection system sends a warning signal to the monitoring station to prompt the personnel at the monitoring station to perform corresponding inspections based on the warning signal.

[0122] As an example of an application scenario of an embodiment of the present application, the inert gas protection system is used to reduce the concentration of combustion-supporting gases and combustible gases in the electrical cabinet to reduce the risk of fire and explosion accidents, thereby achieving active fire prevention and explosion prevention.

[0123] The above energy storage valve fire linkage control system has a dual-redundant communication architecture with a dual energy storage valve control and protection system and a dual inert gas protection system, and realizes the linkage control and protection of the energy storage valve through the battery module control and protection system, the power module control and protection system, the energy storage valve control and protection system, and the inert gas protection system connected in sequence. The number of optical fibers required is small, and it has good economy and high system reliability.

[0124] In some embodiments of the present application, the battery module control and protection system is used to send a thermal runaway risk alarm signal to the power module control and protection system connected to the battery module control and protection system when it is determined that there is a thermal runaway risk in the first battery. The power module control and protection system is used to forward the thermal runaway risk alarm signal to at least one energy storage valve control and protection system connected to the power module control and protection system. Therefore, as an example, at least one energy storage valve control and protection system can determine that there is a thermal runaway risk in the first battery based on the thermal runaway risk alarm signal.

[0125] The power module control and protection system is also used to control the bypass of the energy storage sub-module to which the first battery belongs based on the trigger of the energy storage valve control and protection system, control the disconnection of the power module corresponding to the first battery from the battery module, and send a first control instruction to the battery module control and protection system. The first control instruction is used to trigger the battery module control and protection system to control all the electrical cabinets included in the energy storage sub-module to power off and exit. For example, when at least one energy storage valve control and protection system determines that the first battery has a thermal runaway risk according to the thermal runaway risk alarm signal, at least one energy storage valve control and protection system can trigger the power module control and protection system to control the bypass of the energy storage sub-module to which the first battery belongs, control the disconnection of the power module corresponding to the first battery from the battery module, and cause the power module control and protection system to send a first control instruction to the battery module control and protection system to trigger the battery module control and protection system to control all the electrical cabinets included in the energy storage sub-module to power off and exit, so that the energy storage sub-module to which the first battery belongs stops working, thereby reducing the risk of fire and explosion accidents of the energy storage valve.

[0126] In the above energy storage valve fire linkage control system, the battery module control and protection system is used to upload the thermal runaway risk alarm signal to at least one energy storage valve control and protection system through the power module control and protection system, and the energy storage valve control and protection system is used to trigger the battery module control and protection system through the power module control and protection system, so as to form a feedback closed loop to effectively control the first battery with a thermal runaway risk in a timely manner, protect the energy storage valve in a timely manner, and enable the energy storage valve to operate reliably and stably.

[0127] In some embodiments of the present application, each energy storage valve control and protection system is communicatively connected to other energy storage valve control and protection systems, and each inert gas protection system is communicatively connected to other inert gas protection systems. After such a setting, data sharing can be realized among multiple energy storage valve control and protection systems to build a redundant communication architecture, and data sharing can be realized among multiple inert gas protection systems to build a redundant communication architecture.

[0128] For example, please refer to Figure 2 As described, two energy storage valve control and protection systems are communicatively connected, and two inert gas protection systems are communicatively connected, so that Figure 2 A dual-redundant communication architecture is formed, that is, each energy storage valve control and protection system can implement the functions of the energy storage valve control and protection system described in any of the above embodiments, and each inert gas protection system can implement the functions of the inert gas protection system described in any of the above embodiments.

[0129] In the above energy storage valve fire linkage control system, by setting each energy storage valve control and protection system to be communicatively connected to other energy storage valve control and protection systems, and each inert gas protection system to be communicatively connected to other inert gas protection systems, a linkage control system with a dual-redundant communication architecture can be built to improve the reliability of the system.

[0130] In some embodiments of the present application, one energy storage valve control and protection system among multiple energy storage valve control and protection systems is the first primary system, and the remaining energy storage valve control and protection systems among the multiple energy storage valve control and protection systems are the first standby systems. After such a setting, the first primary system is used to implement the functions of the energy storage valve control and protection system described in any of the above embodiments. For example, the first primary system is used to control the first battery to power off and exit when there is a risk of thermal runaway in the first battery.

[0131] One inert gas protection system among multiple inert gas protection systems is the second primary system, and the remaining inert gas protection systems among the multiple inert gas protection systems are the second standby systems. After such a setting, the second primary system is used to implement the functions of the inert gas protection system described in any of the above embodiments. For example, the second primary system is used to fill the surrounding of the first battery with inert gas when there is a risk of thermal runaway in the first battery.

[0132] For example, please refer to Figure 2 As described, one energy storage valve control and protection system among the 2 energy storage valve control and protection systems is the first primary system, and the other energy storage valve control and protection system is the first standby system; one inert gas protection system among the 2 inert gas protection systems is the second primary system, and the other inert gas protection system is the second standby system.

[0133] The above energy storage valve fire alarm linkage control system can build a linkage control system with a dual-redundancy communication architecture by determining the first primary system, the second primary system, the first standby system, and the second standby system, so as to improve the reliability of the system.

[0134] In some embodiments of the present application, the first primary system and the first standby system are determined by the comparison result between the first health degrees of multiple energy storage valve control and protection systems. The second primary system and the second standby system are determined by the comparison result between the second health degrees of multiple inert gas protection systems. The first health degree is used to represent the failure level of the energy storage valve control and protection system, and the second health degree is used to represent the failure level of the inert gas protection system.

[0135] As an example, please refer to Figure 2 As shown, one energy storage valve control and protection system can be fiber-optically connected to each inert gas protection system and can also be fiber-optically connected to each power module control and protection system, that is, one energy storage valve control and protection system has at least (n + 2) optical fibers. Therefore, in one example, the number of optical fibers with communication anomalies can reflect the failure level of the energy storage valve control and protection system, that is, the first health degree.

[0136] As an example, the inert gas pressure stored in the inert gas protection system can also be used to reflect the fault level of the inert gas protection system, that is, the second health degree. For example, when the inert gas pressure is less than or equal to the first air pressure threshold and greater than the second air pressure threshold, it indicates the first fault level; when the inert gas pressure is less than or equal to the second air pressure threshold, it indicates the second fault level.

[0137] Therefore, by comparing the first health degrees of multiple energy storage valve control protection systems, the first primary system and the first standby system can be determined to achieve the switching of the primary and standby systems. For example, if the first health degrees of 3 energy storage valve control protection systems are in a mild degree, a severe degree, and an emergency degree respectively, then the energy storage valve control protection system with a mild degree is selected as the first primary system, and the other energy storage valve control protection systems are used as the first standby systems.

[0138] Similarly, by comparing the second health degrees of multiple inert gas protection systems, the second primary system and the second standby system can be determined to achieve the switching of the primary and standby systems. For example, if the second health degrees of 2 inert gas protection systems are in a mild degree and a severe degree respectively, then the inert gas protection system with a mild degree is selected as the second primary system, and the other inert gas protection systems are used as the second standby systems.

[0139] It should be noted that, as an example, each energy storage valve control protection system can monitor its own first health degree and then share the first health degree with other energy storage valve control protection systems. Similarly, each inert gas protection system can monitor its own second health degree and then share the second health degree with other inert gas protection systems.

[0140] The above energy storage valve fire linkage control system can determine the first primary system, the first standby system, the second primary system, and the second standby system through the fault level of the system, and achieve the switching of the primary and standby systems, which can improve the effectiveness of the switching.

[0141] Please refer to Figure 3 , in some embodiments of the present application, System A and System B form a redundant communication architecture with each other as the primary and standby systems. For example, System A is Figure 2 any one of the two energy storage valve control protection systems shown in Figure 2 , and System B is Figure 2 the other one of the two energy storage valve control protection systems shown in Figure 2 ; or, System A is

[0142] As a scenario example of this embodiment, based on the comparison result of the health levels (the first health level or the second health level) of System A and System B, one of System A and System B can be determined as the primary system (the first primary system or the second primary system), and the other of System A and System B as the standby system (the first standby system or the second standby system).

[0143] It should be understood that in the actual application process (such as during the process of switching the primary and standby systems), when both System A and System B are the primary systems, the "latter primary" strategy is adopted, that is, the system that becomes the primary system later is used as the primary system. When both System A and System B are the standby systems, the "former primary" strategy is adopted, that is, the system that becomes the standby system earlier is used as the standby system.

[0144] For the above energy storage valve fire protection linkage control system, when both System A and System B are the primary systems (or both are the standby systems), the "latter primary" strategy (or the "former primary" strategy) is adopted to improve the effectiveness of the primary and standby system switching.

[0145] Please refer to Figure 2 , in some embodiments of the present application, as a scenario example of the energy storage valve fire protection linkage control system:

[0146] The energy storage valve control and protection system and the inert gas protection system adopt cross-redundant communication. The data content uploaded by the inert gas protection system to the energy storage valve control and protection system includes but is not limited to: primary and standby status, communication status, self-check status, early warning status, information such as the inert gas protection system having operating conditions, etc., for the energy storage valve control and protection system to perform system switching and linkage control. The data content sent by the energy storage valve control and protection system to the inert gas protection system includes but is not limited to: information such as starting the inert gas replacement mode of the inert gas protection system, communication status, etc., for the inert gas protection system to perform system switching and linkage control.

[0147] As an example, the first primary and standby system includes a first primary system and a first standby system. In the case of any one or more of the following situations: self-check abnormality of the first primary and standby system, combustible gas concentration warning, combustion-supporting gas concentration warning, communication failure between the first primary and standby system and the inert gas protection system, and communication failure between the first primary and standby systems, if there is an inconsistency between the first primary and standby systems, that is, the same target data determined by the first primary system and the first standby system is inconsistent, the data determined by the first primary system shall prevail; or, in the case of at least two of the following situations: self-check abnormality of the first primary and standby system, combustible gas concentration warning, combustion-supporting gas concentration warning, communication failure between the first primary and standby system and the inert gas protection system, and communication failure between the first primary and standby systems, the data determined by the first primary system shall prevail. Such settings are made to achieve functions such as starting, stopping, locking, unlocking, and warning of the energy storage valve.

[0148] As an example, the second primary and standby system includes a second primary system and a second standby system. In the case of any one or more of the following situations: combustible gas concentration warning, combustion-supporting gas concentration warning, starting the inert gas replacement mode, communication failure between the second primary and standby system and the energy storage valve control and protection system, and communication failure between the second primary and standby systems, if there is an inconsistency between the second primary and standby systems, that is, the same target data determined by the second primary system and the second standby system is inconsistent, the data determined by the second primary system shall prevail; or, in the case of at least two of the following situations: combustible gas concentration warning, combustion-supporting gas concentration warning, starting the replacement mode, communication failure between the second primary and standby system and the energy storage valve control and protection system, and communication failure between the second primary and standby systems, the data determined by the second primary system shall prevail. Such settings are made to achieve starting the inert gas replacement mode and warning.

[0149] The above energy storage valve fire linkage control system introduces the switching scenarios of the first primary and standby system and the second primary and standby system through specific scenario examples.

[0150] In some embodiments of the present application, the inert gas protection system is further configured to send a fire risk alarm signal (or called a warning instruction) to the energy storage valve control and protection system when the time for the inert gas protection system to fill inert gas around the first battery is greater than or equal to the first duration and the first battery still has a fire risk (i.e., a thermal runaway risk). The energy storage valve control and protection system is configured to confirm that the first battery has a fire risk according to the fire risk alarm signal.

[0151] As an example, when the inert gas protection system determines that there is a fire risk for the first battery, the inert gas protection system will activate the inert gas replacement mode to fill the electrical cabinet to which the first battery belongs with inert gas, so as to reduce the concentration of combustible gas and combustion-supporting gas in the electrical cabinet, in the hope of eliminating the fire risk existing in the first battery. However, when the time in the inert gas replacement mode (which can be equivalently regarded as the time for filling inert gas around the first battery) is greater than or equal to the first duration, if the first battery still has a fire risk, it means that the concentration of combustible gas or combustion-supporting gas in the electrical cabinet is still relatively high and there is still a fire risk. In this case, the inert gas protection system sends a fire risk alarm signal to the energy storage valve control and protection system, so that the energy storage valve control and protection system can achieve linkage control, that is, trigger the power module control and protection system to control the bypass of the energy storage sub-module to which the first battery belongs, disconnect the power module corresponding to the first battery from the battery module, and trigger the battery module control and protection system to control all the electrical cabinets included in the energy storage sub-module to power off and exit, so as to reduce the risk of fire and explosion accidents of the energy storage valve.

[0152] In the above energy storage valve fire linkage control system, when the time for the inert gas protection system to fill inert gas around the first battery is greater than or equal to the first duration and the first battery still has a fire risk, the inert gas protection system sends a fire risk alarm signal to the energy storage valve control and protection system, which can not only enable the energy storage valve control and protection system to achieve linkage control, but also reduce the risk of false alarm of the fire risk alarm signal by setting the first duration, improve the effectiveness of the linkage control, and reduce the impact on the normal operation of the first battery.

[0153] In some embodiments of the present application, the energy storage valve control and protection system can obtain the first data of the first battery and determine the thermal runaway risk status of the first battery according to the first data of the first battery, where the first data may include at least one of temperature and shell expansion.

[0154] For example, the first data includes temperature. When the temperature of the first battery is greater than or equal to the corresponding temperature threshold, it is determined that the first battery has a thermal runaway risk. As an example, the temperature of the battery can be measured by a relevant temperature sensor (i.e., a fire sensor) and transmitted to the electrical cabinet control and protection system, and based on this, it is determined whether the first battery has a thermal runaway risk. For example, the battery module control and protection system determines whether the first battery has a thermal runaway risk through the electrical cabinet control and protection system.

[0155] For example, the first data includes the degree of expansion of the battery case. When the degree of expansion of the case of the first battery is greater than or equal to the corresponding expansion threshold, it is determined that the first battery has a risk of thermal runaway. It should be understood that when the temperature of the battery is too high, the case of the battery will also expand. Therefore, the risk of thermal runaway of the first battery can be determined by the degree of expansion of the battery case. As an example, the degree of expansion of the battery case can be measured by a relevant visual sensor (i.e., a fire sensor) and transmitted to the electrical cabinet control and protection system to determine whether the first battery has a risk of thermal runaway. For example, the battery module control and protection system determines whether the first battery has a risk of thermal runaway through the electrical cabinet control and protection system.

[0156] For example, the first data includes temperature and the degree of expansion of the battery case. When the temperature of the first battery is greater than or equal to the corresponding temperature threshold and the degree of expansion of the case of the first battery is greater than or equal to the corresponding expansion threshold, it is determined that the first battery has a risk of thermal runaway.

[0157] The above energy storage valve fire linkage control system determines whether the first battery has a risk of thermal runaway based on the temperature and / or the degree of expansion of the battery case, and has the advantage of simple implementation.

[0158] In some embodiments of the present application, the energy storage valve control and protection system can obtain the second data of the first battery and determine the thermal runaway risk status of the first battery according to the second data of the first battery, where the second data may include at least one of the concentration of combustible gas, the concentration of combustion-supporting gas, and the concentration of inert gas.

[0159] For example, the second data includes the concentration of combustible gas. When the concentration of combustible gas in the electrical cabinet is greater than or equal to the corresponding concentration threshold, it is determined that the first battery has a fire risk. For example, combustible gases include, but are not limited to, hydrogen, hydrocarbons, or carbon monoxide. As an example, the concentration of combustible gas in the electrical cabinet can be detected by a gas concentration sensor (i.e., a fire sensor) to determine whether the first battery has a fire risk.

[0160] For example, the second data includes the concentration of combustion-supporting gas. When the concentration of combustion-supporting gas in the electrical cabinet is greater than or equal to the corresponding concentration threshold, it is determined that the first battery has a fire risk. For example, combustion-supporting gases include, but are not limited to, oxygen. As an example, the concentration of combustion-supporting gas in the electrical cabinet can be detected by a gas concentration sensor to determine whether the first battery has a fire risk.

[0161] For example, the second data includes the concentration of inert gas. When the concentration of inert gas in the electrical cabinet is less than or equal to the corresponding concentration threshold, it is determined that there is a fire risk for the first battery. For instance, the inert gas includes, but is not limited to, nitrogen, and the inert gas filled into the electrical cabinet by the inert gas protection system when starting the inert gas replacement mode is nitrogen. As an example, the concentration of inert gas in the electrical cabinet can be detected by a gas concentration sensor to determine whether there is a fire risk for the first battery.

[0162] For example, the second data includes the concentration of combustible gas, the concentration of combustion-supporting gas, and the concentration of inert gas. When the concentration of combustible gas in the electrical cabinet is greater than or equal to the corresponding concentration threshold, the concentration of combustion-supporting gas in the electrical cabinet is greater than or equal to the corresponding concentration threshold, and the concentration of inert gas in the electrical cabinet is less than or equal to the corresponding concentration threshold, it is determined that there is a fire risk for the first battery.

[0163] The above energy storage valve fire-fighting linkage control system determines whether there is a fire risk for the first battery according to the second data of the first battery, and has the advantage of simple implementation.

[0164] Based on the above embodiments, please refer to Figure 4 , in some embodiments of the present application, a control method for the above energy storage valve fire-fighting linkage control system is provided, which specifically includes the following steps:

[0165] 1. The control method of the energy storage valve control and protection system includes:

[0166] (1) The electrical cabinet control and protection system detects in real time to determine whether there is a thermal runaway risk for the first battery. If there is, it reports a thermal runaway risk alarm signal to the battery module control and protection system, and the battery module control and protection system controls the single electrical cabinet to which the first battery belongs to power off and withdraw. Among them, it can be determined whether there is a thermal runaway risk for the first battery through the temperature and / or shell expansion degree of the first battery. For specific details, reference can be made to the description of the above embodiments, which will not be elaborated here.

[0167] (2) The battery module control and protection system uploads the thermal runaway risk alarm signal to the power module control and protection system, so that the power module control and protection system uploads the thermal runaway risk alarm signal to the energy storage valve control and protection system.

[0168] (3) After receiving the thermal runaway risk alarm signal, the energy storage valve control and protection system performs anti-misoperation confirmation. This anti-misoperation confirmation includes: whether multiple energy storage valve control and protection systems have performed main-backup system switching, and the switching is correct, that is, whether the first primary system and the first backup system are confirmed to be correct. It should be understood that the main-backup system switching can be performed in real time, but after the energy storage valve control and protection system receives the thermal runaway risk alarm signal and before triggering the opening of the inert gas replacement mode and the bypass command, it is necessary to confirm again whether the first primary system and the first backup system are correct, that is, anti-misoperation confirmation.

[0169] (4) After the anti-misoperation confirmation of the energy storage valve control and protection system is correct, trigger the interlock control of the inert gas protection system to start the inert gas replacement mode, control the locking of the energy storage valve, trigger the power module control and protection system to bypass a single energy storage sub-module to which the first battery belongs, control the disconnection of the power module corresponding to the first battery from the battery module, and trigger the battery module control and protection system through the power module control and protection system to cut off the power supply of all electrical cabinets included in the single energy storage sub-module and withdraw.

[0170] (5) When the energy storage valve control and protection system determines that the first battery has a risk of thermal runaway or fire, the energy storage valve control and protection system will also upload an alarm signal to the monitoring station to initiate the observation and intervention judgment. If the observation result is that intervention is required, control the energy storage valve to stop operating. For example, manual observation can be carried out to determine whether intervention is needed to stop the energy storage valve. For example, artificial intelligence recognition can also be used to determine whether intervention is needed to stop the energy storage valve.

[0171] II. Control method of the inert gas protection system, including:

[0172] (1) Determine whether the first battery has a fire risk by detecting whether the concentration of combustion-supporting gas or combustible gas in the electrical cabinet to which the first battery belongs is warning. For example, when the concentration of combustion-supporting gas or combustible gas exceeds the corresponding threshold, it is determined that the concentration of combustion-supporting gas or combustible gas gives a warning, thereby determining that the first battery has a fire risk.

[0173] (2) After the inert gas protection system determines that the concentration of combustion-supporting gas or combustible gas gives a warning, determine that the first battery has a fire risk and start the inert gas replacement mode to fill the corresponding electrical cabinet with inert gas to reduce the concentration of combustion-supporting gas and combustible gas in the electrical cabinet.

[0174] (3) When the time in the inert gas replacement mode is greater than or equal to the first duration T1 and the concentration of combustion-supporting gas or combustible gas still gives a warning, that is, the first battery still has a fire risk, the inert gas protection system uploads a fire risk alarm signal to the energy storage valve control and protection system so that the energy storage valve control and protection system can achieve interlock control. For example, trigger the power module control and protection system to bypass a single energy storage sub-module to which the first battery belongs, and trigger the battery module control and protection system through the power module control and protection system to cut off the power supply of all electrical cabinets included in the single energy storage sub-module and withdraw, etc.

[0175] (4) When the inert gas protection system determines that the first battery has a risk of thermal runaway or fire, the inert gas protection system will also upload an alarm signal to the monitoring station to initiate the observation and intervention judgment. If the observation result indicates the need for intervention, the energy storage valve will be controlled to stop operating. For example, manual observation can be carried out to determine whether to intervene and stop the energy storage valve. For example, artificial intelligence recognition can also be used to determine whether to intervene and stop the energy storage valve.

[0176] The control method of the above-mentioned energy storage valve control and protection system can monitor the internal risks (such as the risk of thermal runaway) and external risks (such as the risk of fire) of the battery, and through the interlocking control between the energy storage valve control and protection system and the inert gas protection system, the first battery with a risk of thermal runaway can be effectively controlled and warned in a timely manner, thereby realizing the protection of the energy storage valve and enabling the energy storage valve to operate reliably and stably.

[0177] Please refer to Figure 5 , in some embodiments of the present application, the number of the energy storage valve control and protection system and the inert gas protection system is 1. The interlocking control system further includes n power module control and protection systems and n battery module control and protection systems. The n battery module control and protection systems are in one-to-one correspondence and communication connection with the n power module control and protection systems. The n power module control and protection systems are in communication connection with the energy storage valve control and protection system, and n is an integer greater than or equal to 1.

[0178] It should be understood that Figure 5 For the energy storage valve fire interlocking control system provided by the shown embodiment, except for not having a redundant communication architecture, the functions of the energy storage valve control and protection system, the inert gas protection system, each power module control and protection system, and each battery module control and protection system are as described in the above embodiments and will not be elaborated here.

[0179] For the above-mentioned energy storage valve control and protection system, when the number of the energy storage valve control and protection system and the inert gas protection system is set to 1, the number of optical fibers required is small, and it has good economy. However, it also has the following beneficial effects: It can monitor the internal risks (such as the risk of thermal runaway) and external risks (such as the risk of fire) of the battery, and through the interlocking control between the energy storage valve control and protection system and the inert gas protection system, the first battery with a risk of thermal runaway can be effectively controlled and warned in a timely manner, thereby realizing the protection of the energy storage valve and enabling the energy storage valve to operate reliably and stably.

[0180] Please refer to Figure 6, in some embodiments of the present application, the linkage control system further includes n power module control and protection systems and n battery module control and protection systems. Each battery module control and protection system in the n battery module control and protection systems is communicatively connected to a plurality of energy storage valve control and protection systems, and each power module control and protection system is communicatively connected to a plurality of energy storage valve control and protection systems, where n is an integer greater than or equal to 1.

[0181] It should be understood that Figure 6 The energy storage valve fire linkage control system provided by the illustrated embodiment also has a dual-redundancy communication architecture. The functions of its energy storage valve control and protection system, inert gas protection system, each power module control and protection system, and each battery module control and protection system are as described in the above embodiments and will not be elaborated here.

[0182] It should be noted that since Figure 6 In the energy storage valve fire linkage control system provided by the illustrated embodiment, there is no connection between the battery module control and protection system and the power module control and protection system, but they are directly connected to the energy storage valve control and protection system. Therefore, the battery module control and protection system can directly communicate with the energy storage valve control and protection system without relaying through the power module control and protection system. For example, the battery module control and protection system can directly upload a thermal runaway risk alarm signal to the energy storage valve control and protection system. Moreover, the energy storage valve control and protection system can directly trigger the power-off and withdrawal of all electrical cabinets included in the energy storage sub-module by the battery module control and protection system without passing through the power module control and protection system.

[0183] For the above energy storage valve control and protection system, there is no connection between the battery module control and protection system and the power module control and protection system, but they are directly connected to the energy storage valve control and protection system, which can also achieve the purpose of the embodiments of the present application, that is, it also has the above beneficial effects.

[0184] Please refer to Figure 7 , in some embodiments of the present application, the number of the energy storage valve control and protection system and the inert gas protection system is 1. The linkage control system further includes n power module control and protection systems and n battery module control and protection systems. The n battery module control and protection systems are communicatively connected to the energy storage valve control and protection system, and the n power module control and protection systems are communicatively connected to the energy storage valve control and protection system.

[0185] It should be understood that Figure 7 The energy storage valve fire linkage control system provided by the illustrated embodiment, except for not having a redundant communication architecture, the functions of its energy storage valve control and protection system, inert gas protection system, each power module control and protection system, and each battery module control and protection system are as described in the above embodiments and will not be elaborated here.

[0186] Moreover, there is no connection between the battery module control and protection system and the power module control and protection system. Instead, they are directly connected to the energy storage valve control and protection system. Therefore, the battery module control and protection system can directly communicate with the energy storage valve control and protection system, and the energy storage valve control and protection system can directly trigger the battery module control and protection system to control all the electrical cabinets included in the energy storage sub-module to power off and exit.

[0187] For the above energy storage valve control and protection system, the number of the energy storage valve control and protection system and the inert gas protection system is set to 1, and it also has the above beneficial effects.

[0188] Please refer to Figure 6 or Figure 7 , in some embodiments of the present application, the battery module control and protection system is used to send a thermal runaway risk alarm signal to at least one energy storage valve control and protection system connected to the battery module control and protection system when it is determined that the first battery has a thermal runaway risk.

[0189] For example, as Figure 6 shown, the battery module control and protection system sends thermal runaway risk alarm signals to 2 energy storage valve control and protection systems connected to the battery module control and protection system respectively. Another example is that the battery module control and protection system sends a thermal runaway risk alarm signal to any one of the 2 energy storage valve control and protection systems connected to the battery module control and protection system, and this any one energy storage valve control and protection system can share this thermal runaway risk alarm signal with another energy storage valve control and protection system.

[0190] The energy storage valve control and protection system is used to determine that the first battery has a thermal runaway risk according to the thermal runaway risk alarm signal, and is used to send a second control instruction to the battery module control and protection system and the power module control and protection system. The second control instruction is used to trigger the power module control and protection system to control the bypass of the energy storage sub-module to which the first battery belongs, and is used to trigger the battery module control and protection system to control all the electrical cabinets included in the energy storage sub-module to power off and exit.

[0191] For the above energy storage valve control and protection system, there is no connection between the battery module control and protection system and the power module control and protection system. Instead, they are directly connected to the energy storage valve control and protection system, and the required number of optical fibers doubles, but it also has the above beneficial effects.

[0210] It should be understood that for the specific implementation principles and processes of the above solutions, reference can be made to the description of the foregoing Figures 1 to 7 embodiments shown, which will not be elaborated here.

[0211] In some embodiments, the number of energy storage valve control systems is multiple. One energy storage valve control system among the multiple energy storage valve control systems is the first primary system, and the remaining energy storage valve control systems among the multiple energy storage valve control systems are the first backup systems.

[0212] In the above step S120, determining the first control strategy for controlling the energy storage valve according to the thermal runaway risk condition may include the following steps:

[0213] Determine the first primary system and the first backup systems;

[0214] When it is confirmed that the first primary system and the first backup systems are correct, the first primary system determines the first control strategy for controlling the energy storage valve according to the thermal runaway risk condition.

Determine a second fire protection strategy for the energy storage valve according to the thermal runaway risk status, and determine a second control strategy for controlling the energy storage valve through an energy storage control system communicatively connected to the fire control system.

[0220] It should be understood that for the specific implementation principles and processes of steps S210 and S220, reference can be made to the description of the foregoing Figures 1 to 7 embodiment shown, which will not be elaborated here.

[0221] In some embodiments, when the thermal runaway risk status indicates that there is no thermal runaway risk for the energy storage valve, the second control strategy is to control the energy storage valve to operate normally, and the second fire protection strategy is not to conduct fire protection on the energy storage valve.

[0222] When the thermal runaway risk status indicates that there is a thermal runaway risk for the energy storage valve and the thermal runaway risk is at the first level, the second control strategy is to control the energy storage valve to operate normally, and the second fire protection strategy is to conduct fire protection on the energy storage valve.

[0223] When the thermal runaway risk status indicates that there is a thermal runaway risk for the energy storage valve and the thermal runaway risk is at the second level, the second control strategy is to perform at least one of the following actions: bypass the energy storage sub-module with the thermal runaway risk in the energy storage valve, disconnect the power module with the thermal runaway risk in the energy storage valve from the battery module, power off the battery module with the thermal runaway risk in the energy storage valve, lock the energy storage valve, and stop the operation of the energy storage valve; the second fire protection strategy is to conduct fire protection on the energy storage valve.

[0224] It should be understood that for the specific implementation principles and processes of the above solutions, reference can be made to the description of the foregoing Figures 1 to 7 embodiment shown, which will not be elaborated here.

[0225] In some embodiments, the control method further includes the following steps:

[0226] When the time for the fire control system to conduct fire protection on the energy storage valve is greater than or equal to the first duration and the thermal runaway risk status still indicates that there is a thermal runaway risk for the energy storage valve, send a warning instruction to the energy storage control system.

[0227] The warning instruction is used for the energy storage control system to determine a third control strategy for controlling the energy storage valve.
