Description

Technical Field

[0001] The present application relates to energy storage technology, and in particular to an energy storage system and a control method, device, electronic equipment, and medium for the energy storage system. Background Art

[0002] High-voltage cascade energy storage systems form a high-voltage energy storage array by cascading multiple energy storage units to achieve higher voltage and capacity. High-voltage cascade energy storage systems are commonly used in large-scale power systems to improve grid stability and efficiency.

[0003] In known technologies, high-voltage cascade energy storage systems, in addition to the energy storage unit, also include a control unit, detectors, and ventilation and exhaust units to implement fire prevention functions. Specifically, the detectors monitor the system's preset parameters and send an alarm signal to the control unit when the preset parameters meet corresponding preset conditions. Upon receiving the alarm signal, the control unit activates the ventilation and exhaust units to prevent fire. Furthermore, known technologies increase the number of ventilation and exhaust units to enhance ventilation and improve system safety.

[0004] For a high-voltage cascade energy storage system with multiple ventilation and exhaust units, the control unit is prone to generate large currents when responding to alarm signals and opening or closing ventilation and exhaust units, which can easily lead to thermal runaway and cause safety problems.

[0083] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0084] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0085] High-voltage cascade energy storage systems are a technology for storing and managing energy. They typically involve storing electrical energy in high-voltage batteries or other energy storage devices for release when needed. They are commonly used in large-scale power systems to improve grid stability and efficiency. Specifically, high-voltage cascade energy storage systems form a high-voltage energy storage array by cascading multiple energy storage units.

[0086] Figure 1 It is a structural diagram of a high-voltage cascade energy storage system in the known technology, such as Figure 1As shown, in known technologies, high-voltage cascade energy storage systems, in addition to the aforementioned energy storage unit, also include a control unit, detectors, and ventilation and exhaust units to implement fire prevention functions. Specifically, the detectors monitor preset system parameters and send alarm signals to the control unit when the preset parameters meet corresponding preset conditions. Upon receiving the alarm signal, the control unit activates the ventilation and exhaust units to prevent fire.

[0087] Furthermore, conventional techniques often increase the number of ventilation and exhaust units to enhance ventilation and improve system safety. Specifically, multiple ventilation and exhaust units are installed within the energy storage system. Upon receiving an alarm signal from any detector, the control unit activates these units to quickly control the fire and reduce the risk of fire.

[0088] For the above-mentioned high-voltage cascade energy storage system equipped with multiple ventilation and exhaust units, the control unit is likely to generate a large current when responding to an alarm signal and opening or closing each ventilation and exhaust unit, which can easily lead to thermal runaway and cause safety problems.

[0089] Therefore, the present application provides an energy storage system and a control method, device, electronic device and medium for the energy storage system to solve the above-mentioned problems. Among them, the energy storage system of the present application includes a control unit and at least one energy storage cabin. Specifically, the energy storage cabin is provided with an energy storage unit, a ventilation and exhaust unit, a detector and a relay unit. The relay unit provided in the present application is used to respond to the first alarm signal output by the detector and independently control the ventilation and exhaust unit inside the energy storage cabin to which it belongs, so as to realize ventilation and exhaust inside the energy storage cabin to which it belongs.

[0090] Based on this setting, when any detector outputs the first alarm signal, the corresponding relay unit can independently control the corresponding ventilation and exhaust unit based on the corresponding first alarm signal, effectively reducing the risk of thermal runaway caused by the unified control of all ventilation and exhaust units to open or close, resulting in large currents, thereby facilitating the safe operation of the energy storage system.

[0091] It is understandable that the above configuration is applicable to any energy storage system and is not limited to the aforementioned high-voltage cascade energy storage system.

[0092] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the event that the embodiments do not conflict with each other, the following embodiments and features therein may be combined with each other.

[0093] The embodiment of the present application provides an energy storage system, Figure 2 A schematic diagram of the structure of an energy storage system provided in an embodiment of the present application Figure 1 ,like Figure 2 As shown, an energy storage system provided in an embodiment of the present application includes at least one energy storage compartment.

[0094] Specifically, in this embodiment, silicate panels are used to divide the interior of the energy storage system into multiple independent spaces, forming at least one energy storage compartment. It is understood that in actual applications, the energy storage system can also be divided into multiple independent spaces using panels made of other materials, as long as they are fire-resistant, and this embodiment is not limited to this. Due to the high fire resistance of silicate panels, the use of silicate panels to divide the interior of the energy storage system into independent spaces in this embodiment can achieve better fire isolation.

[0095] like Figure 2 As shown, in this embodiment, each energy storage compartment is equipped with an energy storage unit, a ventilation and exhaust unit, a detector, and a relay unit. Specifically, the interior of the energy storage compartment is divided into a high-pressure area and a low-pressure area, with the energy storage unit located in the high-pressure area and the ventilation and exhaust unit, detector, and relay unit located in the low-pressure area.

[0096] Among them, the detector is used to output a first alarm signal when the first preset parameter of the energy storage cabin meets the first preset condition. Specifically, the detector is used to monitor the first preset parameter inside the energy storage cabin. In this embodiment, the first preset parameter includes carbon monoxide concentration, temperature, and smoke concentration. Accordingly, the detector has the function of monitoring the carbon monoxide concentration, temperature, and smoke concentration inside the energy storage cabin. Specifically, this can be achieved by integrating a carbon monoxide monitoring module, a temperature sensor module, and a smoke concentration monitoring module. It is understandable that the first preset parameter can also include other parameters for monitoring whether the energy storage system needs to take fire prevention measures. This is not limited in this embodiment, as long as the detector integrates the functions of the corresponding modules.

[0097] It can be understood that the first preset condition is used to determine whether fire-fighting measures need to be taken. Therefore, the first preset condition can be whether any of the parameters included in the first preset parameters exceeds the corresponding parameter threshold. When a parameter exceeds the corresponding parameter threshold, the detector outputs a first alarm signal. Exemplarily, if the temperature exceeds the corresponding temperature threshold, the first alarm signal is output. In actual applications, the first preset condition can also be that among the various parameters included in the first preset parameters, at least two parameters exceed the corresponding parameter threshold, and the detector outputs the first alarm signal. The first preset condition can also be that among the various parameters included in the first preset parameters, at least three parameters exceed the corresponding parameter threshold, and the detector outputs the first alarm signal. This is not limited in this embodiment.

[0098] In this embodiment, the relay unit is connected to the detector and the ventilation and exhaust unit located in the same energy storage compartment, and is used to obtain a first alarm signal from the detector and control the ventilation and exhaust unit according to the first alarm signal. The ventilation and exhaust unit includes a fan and an exhaust valve.

[0099] Specifically, the relay unit controls the ventilation and exhaust unit to start or stop based on the first alarm signal. In this embodiment, the first alarm signal includes a first-level alarm signal and a first-level alarm signal, which are output by the detector when the detector detects that at least one of the first preset parameters exceeds the corresponding first threshold value and when the detector detects that at least one of the first preset parameters exceeds the corresponding second threshold value, respectively. Upon receiving the first-level alarm signal, the relay unit controls the corresponding ventilation and exhaust unit to start. Upon receiving the first-level alarm signal, the relay unit controls the corresponding ventilation and exhaust unit to shut down. The first threshold value is less than the second threshold value.

[0100] In this embodiment, a fire extinguishing unit (not shown in the figure) is further provided in the energy storage compartment of the energy storage system. It is understandable that when at least one of the first preset parameters exceeds the corresponding second threshold value, the situation inside the energy storage system is worse than when at least one of the first preset parameters exceeds the corresponding first threshold value. Therefore, when the first and second level alarm signals are received, it is necessary to control the fire extinguishing unit to spray the fire extinguishing agent. At this time, closing the ventilation and exhaust unit can ensure the concentration of the fire extinguishing agent inside the energy storage compartment to ensure the safety of the energy storage system. In this embodiment, detectors are set to perform hierarchical alarms, and the relay units perform corresponding hierarchical control, which can achieve precise control of the energy storage system, thereby facilitating the safety of the system.

[0101] It is understandable that the fire extinguishing unit can be connected to the relay unit and independently controlled by the relay unit.

[0102] like Figure 2 As shown, in this embodiment, the energy storage system further includes a control unit, which is disposed in an independent space distinct from each energy storage compartment. It is understandable that in actual applications, the control unit may also be disposed in one of the energy storage compartments, which is not limited in this embodiment.

[0103] Specifically, the control unit is also configured to receive a first alarm signal from a detector installed in any energy storage compartment and control the corresponding ventilation and exhaust unit based on the received first alarm signal. Furthermore, the energy storage system also includes an audible and visual alarm and a "Do Not Enter" light. Specifically, the control unit activates the audible and visual alarm upon receiving a level 1 alarm signal, and activates both the audible and visual alarm and the "Do Not Enter" light upon receiving a level 1 alarm signal.

[0104] The control unit controls the sound and light alarm and the deflation-preventing light according to the obtained first alarm signal to inform the user of the current status of the energy storage system, which is conducive to the user taking corresponding measures in a timely manner.

[0105] In one possible design, the control unit obtains the first alarm signal through the relay unit. Specifically, when the relay unit obtains the first alarm signal, in addition to controlling the ventilation and exhaust unit according to the first alarm signal, it also synchronizes the first alarm signal to the control unit.

[0106] With this setting, there is no need to connect the control unit to the detector, and the first alarm signal can be obtained through the relay unit, which reduces the number of times the detector transmits data, and thus there is no additional requirement for the performance of the detector.

[0107] Optionally, in actual applications, the control unit may also be directly connected to the detector to obtain the first alarm signal, which is not limited in this embodiment.

[0108] Through the energy storage system in this embodiment, when the first preset parameter of any energy storage compartment meets the first preset condition, the ventilation and exhaust unit in the energy storage compartment can be controlled through the relay unit without having to control all the ventilation and exhaust units in the energy storage system at the same time, thereby avoiding thermal runaway caused by large current when the ventilation and exhaust units are started or shut down at the same time, which is beneficial to ensuring the safe operation of the energy storage system.

[0109] It can be understood that the relay unit has the functions of receiving, forwarding and transmitting data. Therefore, further, as a design, Figure 2 As shown, when the number of energy storage compartments is at least two, the corresponding at least two relay units are connected in parallel to the control unit. Each relay unit can obtain the first alarm signal from the corresponding detector, and receive the first alarm signal sent by the previous relay unit connected, and forward it to the next relay unit until the last relay unit forwards it to the control unit.

[0110] Specifically, upon receiving the first alarm signal from the detector, each relay unit transmits the first alarm signal and the identifier of the energy storage compartment to which it belongs to the relay unit immediately following the current relay unit. After receiving the first alarm signal and identifier sent by the previous relay unit, the relay unit forwards the first alarm signal identifier to the relay unit immediately following the current relay unit, so that the first alarm signal and identifier are transmitted to the control unit via the last relay unit.

[0111] With this setup, only the last relay unit is ultimately connected to the control unit, reducing the number of control unit interface requirements. Furthermore, in this embodiment, the relay unit forwards the first alarm signal with the identifier of the energy storage compartment to which it belongs, allowing the control unit to identify the source of the first alarm signal, thereby facilitating precise control.

[0112] It is understandable that, in actual applications, each relay unit may be connected to the control unit separately, or may be partially connected in parallel to the control unit, which is not limited in this embodiment.

[0113] It should be understood that the energy storage system provided herein is not limited to the energy storage system described in the aforementioned embodiments. In practical applications, the energy storage system may also include an energy storage converter, an energy management unit, etc. It is understood that the aforementioned control unit, relay unit, detector, ventilation and exhaust unit, and fire extinguishing unit are used to implement the fire protection function of the energy storage system.

[0114] Figure 3 A schematic diagram of the structure of an energy storage system provided in an embodiment of the present application Figure 2 ,like Figure 3 As shown, the embodiment of the present application further describes the energy storage system in the aforementioned embodiment in detail based on the aforementioned embodiment.

[0115] like Figure 3 As shown, in the embodiment of the present application, each energy storage unit in the energy storage system includes at least one battery module, and each battery module corresponds to a monitoring module for monitoring a second preset parameter of the battery module. The second preset parameter includes carbon monoxide concentration, temperature, smoke concentration, and hydrogen concentration.

[0116] It is understandable that the monitoring module integrates modules with the functions of monitoring carbon monoxide concentration, temperature, smoke concentration and hydrogen concentration, thereby having the function of obtaining these parameters.

[0117] Specifically, in this embodiment, the monitoring modules are connected to the control unit and transmit a second alarm signal to the control unit when the first preset parameter meets the second preset condition. Accordingly, upon receiving the second alarm signal, the control unit executes at least one of the preset operations. These preset operations include: activating an audible and visual alarm, activating a "Do Not Enter" light, and deactivating the ventilation and exhaust unit.

[0118] In this embodiment, the output terminals of the monitoring modules are connected in parallel to the control unit. The monitoring modules are connected to the control unit via a wired connection, specifically via CAN to fiber optic technology. In actual applications, the monitoring modules can also be connected to the control unit wirelessly to reduce the requirements for the control unit interface.

[0119] Through the above settings, the energy storage system can receive timely alarms when any battery module has problems, which is conducive to taking corresponding measures in a timely manner, thereby ensuring the safety of the energy storage system.

[0120] Specifically, the alarm rules of the monitoring module and the processing rules of the control unit in response to the second alarm signal of the monitoring module are as follows:

[0121] When the monitoring module detects that at least one of the second preset parameters exceeds the corresponding third threshold, it sends a second-level alarm signal included in the second alarm signal to the control unit. When the control unit receives the second-level alarm signal, it executes the preset operation of turning on the sound and light alarm.

[0122] When the monitoring module detects that at least one of the second preset parameters exceeds the corresponding fourth threshold value, it sends a second-level alarm signal included in the second alarm signal to the control unit. When the control unit receives the second-level alarm signal, it executes the preset operations of turning on the sound and light alarm and turning on the deflate and do not enter light.

[0123] It can be understood that the third threshold is smaller than the fourth threshold. When at least one of the second preset parameters exceeds the fourth threshold, it indicates that the current condition of the battery module is more serious than when at least one of the second preset parameters exceeds the third threshold. At this time, fire extinguishing agent needs to be sprayed, so it is necessary to control the deflation-do not enter light to turn on.

[0124] In the above rule settings, the monitoring module can perform graded warnings and enable the control unit to perform corresponding graded control, which can achieve precise control of the energy storage system and enable users to intuitively know the current status of the battery module, which is conducive to ensuring the safety of the energy storage system.

[0125] Optionally, in actual applications, when the control unit receives the second-level alarm signal, it may not execute the preset operation of turning on the sound and light alarm, but only execute the preset operation of turning on the "Do not enter" light. As long as the second-level alarm signal can be distinguished, this is not limited in this embodiment.

[0126] Furthermore, when the monitoring module outputs a Level 2 alarm signal, to ensure the concentration of fire extinguishing agent in the corresponding energy storage compartment and thus the fire extinguishing effect, in one possible design, upon receiving the Level 2 alarm signal, the control unit determines whether the corresponding ventilation and exhaust unit is in an activated state. If so, the control unit performs the preset operations of activating the audible and visual alarms, turning on the "Do Not Enter" light, and deactivating the ventilation and exhaust unit. If not, the control unit performs the preset operations of activating the audible and visual alarms and turning on the "Do Not Enter" light.

[0127] Specifically, the control unit determines whether the ventilation and exhaust unit is in the startup state based on the acquired first alarm signal.

[0128] In this embodiment, if Figure 2 As shown, the control unit also communicates with each ventilation and exhaust unit to obtain status information of the corresponding ventilation and exhaust unit after a preset time of receiving the alarm signal to obtain back-check information.

[0129] Specifically, the alarm signal is at least one of the first alarm signal and the second alarm signal in the aforementioned embodiment. The status information is used to indicate whether the ventilation and exhaust unit is in an operating state or a stopped state, and the checkback information is used to indicate whether the ventilation and exhaust unit requires maintenance, and is obtained based on the alarm signal and the status information.

[0130] It is understood that upon receipt of the first level alarm signal, the ventilation and exhaust unit should be activated. A preset time after the control unit receives the first level alarm signal, the ventilation and exhaust unit should be in an operating state. If the received status information indicates that it is in an operating state, the return check information is used to indicate that the ventilation and exhaust unit does not require maintenance.

[0131] In this embodiment, the preset time is set to 10 seconds in consideration of the data transmission delay. In actual applications, the preset time may be set according to the performance of each part of the energy storage system, which is not limited in this embodiment.

[0132] This setting enables the energy storage system to have the function of back-checking the ventilation and exhaust units, so that when they fail, they can be discovered and repaired in time, which is beneficial to ensuring the safety of the energy storage system.

[0133] In one possible design, Figure 3 As shown, the energy storage system also includes a battery management unit, and the energy storage system implements back-checking of the ventilation and exhaust unit through the battery management unit.

[0134] Specifically, the battery management unit is connected to the control unit and each ventilation and exhaust unit. Upon receiving an alarm signal, the control unit synchronizes the alarm signal to the battery management unit. The battery management unit then obtains status information about the corresponding ventilation and exhaust unit, determines backtest information based on the alarm signal and status information, and feeds the backtest information back to the control unit.

[0135] like Figure 3 As shown, in this embodiment, the battery management unit is set in an independent cabin and is connected to the control unit and the ventilation and exhaust unit via a CAN bus. It is understandable that in actual applications, the connection between the battery management unit and the control unit and the ventilation and exhaust unit can also be achieved wirelessly, which is not limited in this embodiment. In addition, in actual applications, the battery management unit can also be set in one of the energy storage cabins, and can also be set in the same energy storage cabin with the control unit, and is not limited to Figure 3 The situation given in .

[0136] In this embodiment, the control unit cooperates with the battery management unit to realize the back-inspection of the ventilation and exhaust unit. On the one hand, it reduces the burden of the control unit and facilitates the control unit to achieve efficient control. On the other hand, it effectively reduces the hardware and software requirements for the control unit.

[0137] Optionally, since information synchronization takes time, the battery management unit in this embodiment obtains the status information of the corresponding ventilation and exhaust unit when it receives the alarm signal synchronized by the control unit, thereby saving the time of waiting for the preset time to obtain the status information, which is conducive to efficient completion of back-inspection.

[0138] It is understandable that, in actual applications, other controllers with computing power can also be used to cooperate with the control unit in this application to implement the backcheck function, which is not limited in this embodiment.

[0139] An embodiment of the present application further provides a method for controlling an energy storage system, which is specifically applied to a control unit in the above energy storage system. Figure 4 A schematic diagram of a control method for an energy storage system provided in an embodiment of the present application Figure 1 ,like Figure 4 As shown, the control method of this embodiment includes:

[0140] S401, obtaining a first alarm signal output by any energy storage compartment.

[0141] The first alarm signal is output by a detector in the energy storage compartment when a first preset parameter of the energy storage compartment satisfies a first preset condition. For details regarding the energy storage compartment, the detector, and the first preset parameter, please refer to the aforementioned embodiments and will not be elaborated upon here.

[0142] In this embodiment, the first preset condition is specifically: when at least one of the first preset parameters exceeds a corresponding first threshold, the corresponding detector outputs a first-level alarm signal; when at least one of the first preset parameters exceeds a corresponding second threshold, the corresponding detector outputs a first-level alarm signal. The first threshold is less than the second threshold.

[0143] S402: Control the ventilation and exhaust unit in the corresponding energy storage compartment according to the first alarm signal.

[0144] In this embodiment, upon receiving a Level 1 alarm signal, the control unit controls the ventilation and exhaust units in the corresponding energy storage compartment to open, thereby promptly reducing the current value corresponding to the first preset parameter. Upon receiving a Level 1 or 2 alarm signal, the control unit controls the ventilation and exhaust units in the corresponding energy storage compartment to close, as fire extinguishing agent spraying is required. This ensures the concentration of fire extinguishing agent within the compartment and allows for timely control of the fire.

[0145] Optionally, in actual applications, the control unit can also be configured to turn on the sound and light alarm when receiving the first level alarm signal, and turn on the "Do not enter" light when receiving the first level alarm signal, to warn the user of the current danger level of the energy storage system.

[0146] In the above process, when any detector outputs the first alarm signal, the control unit independently controls the corresponding ventilation and exhaust unit. If not all detectors output the first alarm signal, the control unit will not control all ventilation and exhaust units at the same time, thereby effectively reducing the thermal runaway problem caused by the simultaneous startup or shutdown of the ventilation and exhaust units, which is conducive to the safe operation of the energy storage system.

[0147] Optionally, in actual applications, the control unit obtains the first alarm signal through the relay unit, and realizes independent control of each ventilation and exhaust unit through the relay unit, that is, the relay unit obtains the first alarm signal output by the detector, controls the corresponding ventilation and exhaust unit according to the first alarm signal, and synchronizes the first alarm signal to the control unit. For details, please refer to the contents of the aforementioned embodiments, which is not limited in this embodiment.

[0148] S403: Acquire a second alarm signal output by any monitoring module.

[0149] The second alarm signal is output by the monitoring module when the second preset parameter of the battery module meets the second preset condition. Specifically, for the definition of the monitoring module, the battery module, and the definition of the second preset parameter, please refer to the above embodiment and will not be repeated here.

[0150] In this embodiment, the second alarm signal includes a second-level alarm signal and a second-level alarm signal. Accordingly, the second preset condition is: when at least one of the second preset parameters of the battery module exceeds a third threshold, the corresponding monitoring module outputs the second-level alarm signal. When at least one of the second preset parameters of the battery module exceeds a fourth threshold, the corresponding monitoring module outputs the second-level alarm signal, wherein the third threshold is less than the fourth threshold.

[0151] S404: Execute at least one of the preset operations according to the second alarm signal.

[0152] Among them, the preset operations include: turning on the sound and light alarm, turning on the "Do Not Enter" light, and turning off the ventilation and exhaust unit.

[0153] Specifically, in this embodiment, the control unit executes the preset operation of turning on the sound and light alarm when receiving the second level alarm signal. It also executes the preset operation of turning on the sound and light alarm and turning on the "Do Not Enter" light when receiving the second level alarm signal. Furthermore, when the control unit receives the first level alarm signal to turn on the ventilation and exhaust unit, it also executes the preset operation of turning off the ventilation and exhaust unit.

[0154] Through this setting, when a problem occurs in any battery module, the control unit can respond to the alarm signal output by the monitoring module to perform corresponding control and execute at least one of the preset operations. On the one hand, it can effectively reduce the risk of dangerous situations caused by battery modules, and on the other hand, it can provide timely feedback to users.

[0155] It is understandable that, in this embodiment, the execution order of S401 and S403 is not limited.

[0156] S405: When receiving either the first alarm signal or the second alarm signal, sending a check instruction to the battery management unit.

[0157] When the battery management unit receives the checkback instruction, it obtains the status information of the corresponding ventilation and exhaust unit, and the status information is used to indicate whether the ventilation and exhaust unit is in a working state or a stopped state.

[0158] S406: Receive the check information fed back by the battery management unit.

[0159] Specifically, the inspection information is used to indicate whether the ventilation and exhaust unit needs to be inspected.

[0160] In this embodiment, the battery management unit completes the back-check of each ventilation and exhaust unit, which can effectively reduce the burden of the control unit, thereby ensuring the performance of the control unit and facilitating the safe operation of the energy storage system.

[0161] In actual applications, when the control unit receives at least one of the first alarm signal and the second alarm signal, it can also directly obtain the status information of the corresponding ventilation and exhaust unit after a preset time interval, and determine whether the corresponding ventilation and exhaust unit needs to be repaired based on the alarm signal and status information. This is not limited in this embodiment.

[0162] An embodiment of the present application further provides a control method for an energy storage system, which is specifically applied to a relay unit in the above energy storage system. Figure 5 A schematic diagram of a control method for an energy storage system provided in an embodiment of the present application Figure 2 ,like Figure 5 As shown, the control method of this embodiment includes:

[0163] S501: Acquire a first alarm signal output by a detector of the energy storage compartment.

[0164] The first alarm signal is output by the detector when the first preset parameter of the energy storage compartment satisfies the first preset condition. For specific definitions of the energy storage compartment and the detector, as well as the first preset parameter and the first preset condition, please refer to the definitions of S401 in the previous embodiment and will not be repeated here.

[0165] Specifically, in this embodiment, when the energy storage system includes at least two energy storage compartments, the corresponding at least two relay units are connected in parallel to the control unit. The process of the relay unit sending the first alarm signal to the control unit is as follows:

[0166] The obtained first alarm signal and the identifier of the energy storage compartment to which it belongs are sent to the next relay unit of the current relay unit; after obtaining the first alarm signal and identifier sent by the previous relay unit, the first alarm signal and identifier are forwarded to the next relay unit of the current relay unit, so that the first alarm signal and identifier are sent to the control unit through the last relay unit.

[0167] It can be understood that the next relay unit is a relay unit between the current relay unit and the control unit, and the current relay unit is a relay unit between the previous relay unit and the control unit.

[0168] Each relay unit can receive the first alarm signal and forward or send the first alarm signal, so that the control unit can receive the first alarm signal received by each relay unit without adding additional interfaces.

[0169] Optionally, in actual applications, each relay unit may be connected to the control unit respectively, and upon receiving the first alarm signal, the relay unit directly sends the first alarm signal to the control unit. This is not limited in this embodiment.

[0170] S502: Control the ventilation and exhaust unit in the energy storage compartment according to the first alarm signal, and send the first alarm signal to the control unit so that the control unit controls the ventilation and exhaust unit according to the first alarm signal.

[0171] In this embodiment, the relay unit independently controls the corresponding ventilation and exhaust unit according to the first alarm signal and sends the first alarm signal to the control unit, which is beneficial for the accurate control of the control unit during overall control, thereby ensuring the safe operation of the energy storage system.

[0172] As an example, Figure 6 A flow chart of fire control of an energy storage system provided in an embodiment of the present application is shown as follows: Figure 6 As shown, for the energy storage system in the aforementioned embodiment, when it is in operation, each detector monitors the first preset parameter of the corresponding energy storage compartment, and each monitoring module monitors the second preset parameter of the corresponding battery module.

[0173] When at least one of the corresponding first preset parameters of each detector exceeds the corresponding first threshold, the detector outputs a first-level alarm signal to the relay unit. The relay unit responds to the first-level alarm signal to turn on the ventilation and exhaust unit, and sends the first-level alarm signal to the control unit. The control unit responds to the first-level alarm signal to turn on the sound and light alarm.

[0174] When at least one of the corresponding first preset parameters of each detector exceeds the corresponding second threshold, the detector outputs the first and second level alarm signals to the relay unit. The relay unit closes the ventilation and exhaust unit in response to the first and second level alarm signals, and sends the first and second level alarm signals to the control unit. The control unit turns on the sound and light alarm and the do not enter light in response to the first and second level alarm signals, and sprays the fire extinguishing agent.

[0175] When at least one of the corresponding second preset parameters of each monitoring module exceeds the corresponding third threshold, the monitoring module outputs a second first-level alarm signal to the control unit, and the control unit turns on the sound and light alarm in response to the second first-level alarm signal.

[0176] When at least one of the corresponding second preset parameters exceeds a fourth threshold, each monitoring module outputs a second-level alarm signal to the control unit. In response to the second-level alarm signal, the control unit activates the audible and visual alarms and the "Do Not Enter" light. Simultaneously, the control unit determines whether it has received a first-level alarm signal from the detector in the corresponding energy storage compartment and activates the ventilation and exhaust unit. If so, it simultaneously deactivates the ventilation and exhaust unit and sprays the fire extinguishing agent.

[0177] The present application also provides a method for controlling an energy storage system, which is specifically applied to the battery management unit in the above energy storage system. Specifically, the method includes:

[0178] Acquire an alarm signal synchronized by a control unit in the energy storage system, where the alarm signal is a first alarm signal output by a detector in the energy storage system and / or a second alarm signal output by a monitoring module in the energy storage system;

[0179] In response to the alarm signal, the status information of the corresponding ventilation and exhaust unit in the energy storage system is obtained, where the status information is used to indicate whether the ventilation and exhaust unit is in an operating state or a stopped state;

[0180] Based on the alarm signal and status information, the back-inspection information is determined and sent to the control unit; the back-inspection information is used to indicate whether the ventilation and exhaust unit needs to be repaired.

[0181] In this embodiment, the battery management unit receives an alarm signal synchronized with the control unit, obtains status information of the corresponding ventilation and exhaust unit, and determines whether the corresponding ventilation and exhaust unit needs maintenance based on the alarm signal and status information. When a failure occurs in the ventilation control unit, the problem can be discovered in a timely manner, which is conducive to timely maintenance, thereby ensuring the safe operation of the energy storage system.

[0182] As an example, Figure 7A A schematic diagram of a process for checking the ventilation and exhaust unit in an energy storage system according to an embodiment of the present application Figure 1 ,like Figure 7AAs shown, when any detector outputs a Level 1 alarm signal, the relay unit responds to the Level 1 alarm signal by activating the corresponding ventilation and exhaust unit and transmitting the Level 1 alarm signal to the control unit. The control unit synchronizes the Level 1 alarm signal to the battery management unit, which then obtains status information about the corresponding ventilation and exhaust unit. If the status information indicates that the ventilation and exhaust unit is in operation, it indicates that the ventilation and exhaust unit is normal and requires no maintenance. If the status information indicates that the ventilation and exhaust unit is in a stopped state, it indicates that the ventilation and exhaust unit is faulty and requires maintenance. In this case, a return check message indicating that the ventilation and exhaust unit needs to be repaired is reported to the control unit.

[0183] It can be understood that when receiving multiple first-level alarm signals, the battery management unit can simultaneously obtain the status information of multiple corresponding ventilation and exhaust units, and determine whether the corresponding ventilation and exhaust units need maintenance based on the corresponding first-level alarm signals and status information.

[0184] Figure 7B A schematic diagram of a process for checking the ventilation and exhaust unit in an energy storage system according to an embodiment of the present application Figure 2 ,like Figure 7B As shown, when any detector outputs a first or second level alarm signal, the relay unit shuts down the corresponding ventilation and exhaust unit in response to the first or second level alarm signal and transmits the first or second level alarm signal to the control unit. The control unit synchronizes the first or second level alarm signal to the battery management unit, which then obtains status information about the corresponding ventilation and exhaust unit. If the status information indicates that the ventilation and exhaust unit is in a stopped state, it indicates that the ventilation and exhaust unit is normal and does not require maintenance. If the status information indicates that the ventilation and exhaust unit is in an operating state, it indicates that the ventilation and exhaust unit is faulty and requires maintenance. In this case, a return check message indicating that the ventilation and exhaust unit needs to be repaired needs to be reported to the control unit.

[0185] Figure 7C A schematic diagram of a process for checking the ventilation and exhaust unit in an energy storage system according to an embodiment of the present application Figure 3 ,like Figure 7C As shown, when any monitoring module outputs a second-level alarm signal, the control unit simultaneously receives a first-level alarm signal output by the corresponding detector. The control unit then shuts down the corresponding ventilation and exhaust unit and synchronizes the second-level alarm signal and the first-level alarm signal to the battery management unit. The battery management unit obtains the status information of the corresponding ventilation and exhaust unit. If the status information indicates that the ventilation and exhaust unit is in a stopped state, it means that the ventilation and exhaust unit is normal and does not require maintenance. If the status information indicates that the ventilation and exhaust unit is in a working state, it means that the ventilation and exhaust unit is faulty and requires maintenance. At this time, it is necessary to report to the control unit a return inspection information indicating that the ventilation and exhaust unit needs to be repaired.
