Description

Technical Field

[0001] This application relates to the field of new energy technology, and in particular to a status display and control method, device, controller, system, medium and product for an energy storage device. Background Technology

[0002] With the rapid development of the new energy industry, energy storage devices are being used more and more widely. These devices are typically constructed by combining multiple battery units, achieving large-scale energy storage and release through the coordinated operation of these units. Indicating the operating status of these energy storage devices is crucial for their reliable operation.

[0003] In related technologies, it is often necessary to determine whether an energy storage device is operating malfunctioning, and control the operating status of the indicator device on the energy storage device based on the determination result, so as to provide feedback on whether the energy storage device is operating malfunctioning.

[0004] However, the relevant technologies cannot accurately reflect the state of energy storage devices, which can easily lead to errors in the judgment of the state of energy storage devices and affect the reliable operation of energy storage devices. Summary of the Invention

[0005] Based on this, this application provides a status display and control method, device, controller, system, medium, and product for an energy storage device, which can improve the accuracy of determining the status of the energy storage device, thereby improving the operational reliability of the energy storage device.

[0006] In a first aspect, this application provides a status display control method for an energy storage device. The method includes: acquiring operating status data of each battery device in the energy storage device and auxiliary operating data of an energy storage auxiliary device in the energy storage device; determining the operating status of each battery device based on the operating status data, and determining the comprehensive fault level of the energy storage device based on the auxiliary operating data and the operating status data; determining a secondary controller that communicates normally with a primary controller and a data acquisition module that communicates normally with each secondary controller based on the operating status data of each battery device; controlling the operating status of an energy storage indicator device based on the operating status of each battery device, the comprehensive fault level, and the secondary controller that communicates normally with the primary controller; and controlling the operating status of each module indicator device based on the operating status of each battery device, the battery fault level of each battery device in the comprehensive fault level, and the data acquisition module that communicates normally with each secondary controller.

[0007] The technical solution provided in this application embodiment achieves full coverage of the core operating information of the energy storage device by acquiring the operating status data of each battery device and the auxiliary operating data of the energy storage auxiliary device. This avoids the problem of inaccurate status judgment caused by a single data source and improves the accuracy of determining the status of the energy storage device. Based on the operating status data, working status, and comprehensive fault level of each battery device, the operating status of the indicator device in the energy storage device is controlled. This allows the operating status of the indicator device to be determined from the operating status and working status of each battery device, as well as from the comprehensive fault level of the energy storage device, so that the operating status of the indicator device can comprehensively reflect the status of the energy storage device. Instead of simply reporting whether the energy storage device is malfunctioning, this system accurately determines the energy storage device's status based on the operating status of the indicator devices, improving the accuracy of the determined status and thus enhancing the device's operational reliability. Furthermore, by controlling the operating status of the energy storage indicator devices and the indicator devices of each module, a hierarchical control scheme for the indicator device's operating status is constructed. This enables precise differentiation and display of the overall and partial status of the energy storage device, effectively solving the technical problem of difficulty in accurately judging the energy storage device's status due to mixed display of overall and partial statuses. Therefore, it improves the accuracy and intuitiveness of the energy storage device's status display.

[0008] In some embodiments, the operating state of the energy storage indicator is controlled according to the operating state of each battery device, the overall fault level, and the secondary controller that is in normal communication with the primary controller. This includes: controlling the operating state of the first display device in the energy storage indicator according to the operating state of each battery device; controlling the operating state of the second display device in the energy storage indicator according to the overall fault level; and controlling the operating state of the third display device in the energy storage indicator according to the secondary controller that is in normal communication with the primary controller.

[0009] In the technical solution provided in this application embodiment, the energy storage indicator device is divided into three types of display devices. The operating status of the first display device is controlled according to the working status of each battery device, the operating status of the second display device is controlled according to the comprehensive fault level, and the operating status of the third display device is controlled according to the second-level controller that is in normal communication with the first-level controller. In this way, the working status, comprehensive fault level, and communication topology status of the battery device are independently displayed at the physical level. This effectively solves the technical problem of information confusion and identification difficulties caused by multiple status information superimposed on a single indicator device. It is beneficial to intuitively obtain the corresponding dimension status information at the energy storage device level through different display devices, thereby improving the accuracy and intuitiveness of the energy storage device status display.

[0010] In some embodiments, controlling the operating state of the first display device in the energy storage indicator device according to the operating state of each battery device includes: when the first display device includes a single display device, determining the number of battery devices powered on in the energy storage device according to the operating state of each battery device, and controlling the operating state of the first display device according to the number of battery devices powered on and the total number of battery devices in the energy storage device; when the first display device includes a first main display device and each first slave display device that indicates the state of each battery device in the energy storage device, determining the operating state of the energy storage device and the operating state of each battery device according to the operating state of each battery device; controlling the operating state of the first main display device according to the operating state of the energy storage device, and controlling the operating state of each first slave display device according to the operating state of each battery device.

[0011] The technical solution provided in this application provides two parallel implementation methods for the first display device. It can control the operating status of the first display device when it includes a single display device, or it can coordinate the operating status of the first main display device and each first slave display device when the first display device includes a first main display device and each first slave display device. In this way, a flexible control scheme compatible with different hardware configurations is constructed, which effectively solves the technical problem that it is difficult to accurately control due to different configurations of indicator devices caused by differences in the scale of energy storage devices or cost constraints. It can select the appropriate indicator mode according to the actual application scenario, thereby improving the universality and configuration flexibility of the energy storage device status indicator scheme.

[0012] In some embodiments, controlling the operating state of the second display device in the energy storage indicator according to the overall fault level includes: when the second display device includes a single display device, controlling the operating state of the second display device according to the overall fault level of the energy storage device in the overall fault level; when the second display device includes a second main display device and each second slave display device that indicates the state of each battery device in the energy storage device respectively, controlling the operating state of the second main display device according to the overall fault level of the energy storage device in the overall fault level, and controlling the operating state of each second slave display device according to the battery fault level of each battery device in the overall fault level.

[0013] The technical solution provided in this application provides two parallel implementation methods for the second display device. One method controls the operating status of the second display device when it includes a single display device, while the other method coordinates the operating status of the second main display device and each second slave display device when the second display device includes a second main display device and several second slave display devices. This achieves hierarchical differentiation between the overall fault level of the energy storage device and the fault levels of each battery device, effectively solving the technical problem of being unable to distinguish between overall and local faults due to fault level information being aggregated in a single indicator device. Furthermore, it allows for flexible selection of the granularity of fault information presentation based on hardware configuration, thereby improving the versatility and configuration flexibility of the energy storage device status indication scheme.

[0014] In some embodiments, controlling the operating state of a third display device in an energy storage indicator based on a secondary controller that communicates normally with a primary controller includes: when the third display device comprises a single display device, controlling the operating state of the third display device based on the number of secondary controllers that communicate normally with the primary controller and the total number of secondary controllers in the energy storage device; when the third display device comprises a third main display device and each third slave display device that indicates the state of each battery device in the energy storage device, controlling the operating state of the third main display device based on the number of secondary controllers that communicate normally with the primary controller and the total number of secondary controllers in the energy storage device, and controlling the operating state of each third slave display device based on the identifier of the secondary controller that communicates normally with the primary controller.

[0015] The technical solution provided in this application provides two parallel implementation methods for the third display device. It can control the operating status of the third display device when it includes a single display device, or it can coordinate the operating status of the third main display device and each third slave display device when the third display device includes a third main display device and each third slave display device. In this way, the overall status of the communication topology and the online status of each secondary controller are displayed in a coordinated manner. This effectively solves the technical problem that the specific offline battery device cannot be located because the communication status information is aggregated on a single indicator device. It can flexibly select the granularity of the communication status presentation according to the hardware configuration, thereby improving the accuracy and location of the communication topology status indication.

[0016] In some embodiments, the operating state of each module indicator device is controlled according to the operating state of each battery device, the battery fault level of each battery device in the comprehensive fault level, and the acquisition module that communicates normally with each secondary controller. This includes: for each secondary controller, controlling the operating state of the fourth display device in the module indicator device on the energy storage module to which the secondary controller belongs, according to the operating state of the battery device managed by the secondary controller; for each secondary controller, controlling the operating state of the fifth display device in the module indicator device on the energy storage module to which the secondary controller belongs, according to the battery fault level of the battery device managed by the secondary controller in the comprehensive fault level; and for each secondary controller, controlling the operating state of the sixth display device in the module indicator device on the energy storage module to which the secondary controller belongs, according to the acquisition module that communicates normally with the secondary controller.

[0017] In the technical solution provided in this application embodiment, the module indicator device on the energy storage module is further divided into three types of display devices. For each secondary controller, the operating status of the fourth display device is controlled according to the working status of the battery device it manages, the operating status of the fifth display device is controlled according to the battery fault level of the battery device, and the operating status of the sixth display device is controlled according to the acquisition module that communicates normally with the secondary controller. In this way, the battery working status, battery fault level, and acquisition module communication status are displayed independently at the physical level. This effectively solves the technical problem of status confusion and difficulty in identification caused by the superposition of multiple status information inside the module on a single indicator device. It is beneficial to intuitively obtain the corresponding dimension status information at the energy storage module level through different display devices, thereby improving the accuracy and intuitiveness of the energy storage module status display.

[0018] In some embodiments, controlling the operating state of a fourth display device in a module indication device on an energy storage module to which the secondary controller belongs, based on the operating state of the battery devices managed by the secondary controller, includes: when the fourth display device includes a single display device, determining the number of battery devices powered on by the secondary controller based on the operating state of the battery devices managed by the secondary controller; controlling the operating state of the fourth display device based on the number of battery devices powered on by the secondary controller and the total number of battery devices managed by the secondary controller; when the fourth display device includes multiple first sub-display devices, each first sub-display device indicating a battery device managed by the secondary controller, determining the identifier of the powered-on battery device among the battery devices managed by the secondary controller based on the operating state of the battery devices managed by the secondary controller; and controlling the operating state of each first sub-display device based on the identifier of the powered-on battery device.

[0019] The technical solution provided in this application provides two parallel implementation methods for the fourth display device. It can control the operating status of the fourth display device when it includes a single display device, or it can control the operating status of multiple first sub-display devices when the fourth display device includes multiple first sub-display devices. In this way, a flexible control scheme compatible with different indication granularities is constructed, which effectively solves the technical problem that it is difficult to accurately control due to different configurations of indication devices caused by differences in the scale of energy storage modules. Thus, the appropriate indication mode can be selected according to the actual application scenario, thereby improving the versatility and configuration flexibility of the energy storage module status indication scheme.

[0020] In some embodiments, controlling the operating state of a fifth display device in a module indication device on an energy storage module to which the secondary controller belongs, based on the battery fault level of the battery device managed by the secondary controller in the comprehensive fault level, includes: when the fifth display device is a single display device, controlling the operating state of the fifth display device based on the maximum fault level in the battery fault levels of the battery device managed by the secondary controller; and when the fifth display device includes multiple second sub-display devices, each second sub-display device indicating a respective battery fault level, controlling the operating state of each second sub-display device based on the battery fault level of the battery device managed by the secondary controller.

[0021] The technical solution provided in this application provides two parallel implementation methods for the fifth display device. It can control the operating status of the fifth display device when it is a single display device, or it can control the operating status of each second sub-display device when the fifth display device includes multiple second sub-display devices. In this way, a flexible control scheme compatible with different fault presentation granularities is constructed, which effectively solves the technical problem that the specific fault conditions of each battery device under the jurisdiction of the secondary controller cannot be distinguished because fault level information is aggregated into a single indicator device. It can select the appropriate fault presentation mode according to the actual application scenario, thereby improving the versatility and configuration flexibility of the energy storage module fault indication scheme.

[0022] In some embodiments, controlling the operating state of the sixth display device in the module indicator device on the energy storage module to which the secondary controller belongs, based on the acquisition module that communicates normally with the secondary controller, includes: when the sixth display device is a single display device, controlling the operating state of the sixth display device based on the number of acquisition modules that communicate normally with the secondary controller and the total number of acquisition modules under the secondary controller; when the sixth display device includes multiple third sub-display devices, each of which indicates the state of each acquisition module under the secondary controller, controlling the operating state of each third sub-display device based on the identifier of the acquisition module that communicates normally with the secondary controller.

[0023] The technical solution provided in this application provides two parallel implementation methods for the sixth display device. This allows control of the operating state of the sixth display device when it is a single display device, and also allows control of the operating state of multiple third sub-display devices when the sixth display device includes multiple third sub-display devices. This constructs a flexible control scheme compatible with different communication state presentation granularities, effectively solving the technical problem of being unable to locate specific offline acquisition modules due to the aggregation of communication state information from acquisition modules onto a single indicator device. It allows selection of an appropriate communication state presentation mode based on the actual application scenario, thereby improving the versatility and locatability of the acquisition module communication state indication scheme.

[0024] In some embodiments, each battery device is connected to a bus via a switch, and the operating status data includes first voltage data at the end of each switch connected to the battery device and second voltage data at the end of each switch connected to the bus. Determining the operating status of each battery device based on the operating status data includes: determining the operating status of each battery device based on the first voltage data at the end of each switch connected to the battery device and the second voltage data at the end of each switch connected to the bus.

[0025] In the technical solution provided in this application embodiment, the working state of each battery device is determined based on the first voltage data of the end of each switch connected to the battery device and the second voltage data of the end of each switch connected to the bus. Thus, the working state of each battery device can be determined without waiting for data accumulation, reducing the phenomenon of lag in the determination of the working state of each battery device and improving the accuracy of the determination of the working state of each battery device.

[0026] In some embodiments, the operating status data includes voltage data of each cell in each battery device; determining the overall fault level of the energy storage device based on auxiliary operating data and operating status data includes: for each battery device, determining the battery fault level of the battery device based on the voltage data of each cell in the battery device; determining the auxiliary control fault level based on the auxiliary operating data, and determining the overall fault level of the energy storage device based on the auxiliary control fault level and the battery fault levels of each battery device; and determining the overall fault level of the energy storage device and the battery fault levels of each battery device as the combination of the overall fault level of the energy storage device and the battery fault levels of each battery device as the overall fault level of the energy storage device.

[0027] In the technical solution provided in this application embodiment, the comprehensive fault level includes the overall fault level and the battery fault level of each battery device. The overall fault level can reflect the combined fault situation of battery faults and auxiliary control faults, while the battery fault level of each battery device can reflect the fault situation of the cells inside each battery device. This realizes the hierarchical characterization of the fault state of the energy storage device, so the comprehensive fault level can accurately and comprehensively reflect the fault situation of the energy storage device, improving the accuracy and comprehensiveness of the determined fault level of the energy storage device.

[0028] In some embodiments, determining the battery fault level of the battery device based on the voltage data of each cell in the battery device includes: determining the battery fault level as a first fault level when the voltage data of each cell in the battery device are all within the range of the minimum allowable voltage data to the maximum allowable voltage data; determining the battery fault level as a second fault level when the maximum voltage data of each cell in the battery device is greater than the maximum allowable voltage data, and the difference between the maximum voltage data and the maximum allowable voltage data is less than or equal to a preset voltage data; determining the battery fault level as a third fault level when the minimum voltage data of each cell in the battery device is less than the minimum allowable voltage data, and the difference between the minimum allowable voltage data and the minimum voltage data is less than or equal to a set voltage data; determining the battery fault level as a third fault level when the difference between the minimum allowable voltage data and the minimum voltage data is greater than the set voltage data.

[0029] In the technical solution provided in this application embodiment, the minimum allowable voltage data and the maximum allowable voltage data are used as reference thresholds. Based on whether the voltage data of each cell deviates from the reference threshold, and the comparison result of the deviation value of the voltage data of each cell relative to the reference threshold with the fixed voltage data (i.e., preset voltage data or set voltage data), the battery fault level is refined into a first fault level, a second fault level, and a third fault level. This allows for the quantitative classification of fault severity based on the magnitude of the deviation value, achieving a refined assessment of overvoltage and undervoltage faults in the battery device. This not only effectively solves the technical problem of not being able to determine the fault of the battery device at the cell level, but also effectively solves the technical problem of not being able to distinguish between minor and serious faults by simply judging whether the voltage exceeds the limit. This improves the accuracy and refinement of the determined battery fault level.

[0030] In some embodiments, determining the overall fault level of the energy storage device based on the auxiliary control fault level and the battery fault level of each battery device includes: determining the overall fault level of the energy storage device as a first fault level when both the auxiliary control fault level and the battery fault level of each battery device are first fault levels; determining the overall fault level of the energy storage device as a second fault level when both the auxiliary control fault level and the battery fault level of each battery device are less than or equal to a second fault level, and at least one of the auxiliary control fault level and the battery fault level of each battery device is a second fault level; and determining the overall fault level of the energy storage device as a third fault level when at least one of the auxiliary control fault level and the battery fault level of each battery device is greater than the second fault level.

[0031] The technical solution provided in this application provides a hierarchical system of first fault level, second fault level and third fault level, which are progressively advanced. The overall fault level of the energy storage device is determined by using a step-by-step judgment logic rule. This effectively solves the problem of not being able to determine the overall fault level of the energy storage device. The overall fault level of the energy storage device can be determined by comprehensively considering the auxiliary control fault level and the battery fault level of each battery device. Therefore, the determined overall fault level of the energy storage device can accurately reflect the overall fault status of the energy storage device, thus improving the accuracy and reliability of the determined overall fault level of the energy storage device.

[0032] Secondly, this application provides a status display and control device for an energy storage device. The device includes: an acquisition module for acquiring operating status data of each battery device in the energy storage device, and auxiliary operating data of an energy storage auxiliary device in the energy storage device; an operating status determination module for determining the operating status of each battery device based on the operating status data; a fault level determination module for determining the comprehensive fault level of the energy storage device based on the auxiliary operating data and the operating status data; a communication determination module for determining a secondary controller that communicates normally with a primary controller and an acquisition module that communicates normally with each secondary controller based on the operating status data of each battery device; an energy storage indication control module for controlling the operating status of the energy storage indication device based on the operating status of each battery device, the comprehensive fault level, and the secondary controller that communicates normally with the primary controller; and a module indication control module for controlling the operating status of each module indication device based on the operating status of each battery device, the battery fault level of each battery device in the comprehensive fault level, and the acquisition module that communicates normally with each secondary controller.

[0033] Thirdly, this application provides a controller, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the method of any one of the first aspects.

It should also be noted that any step in the embodiments of this application can be executed independently, that is, the execution of any step in the above embodiments can be performed without depending on the execution of other steps.

[0067] From a market perspective, energy storage devices are becoming increasingly widely used, bringing significant convenience to daily production and life. Energy storage devices typically include multiple battery units, which can be connected in series, parallel, or a combination of series and parallel connections. For example, in this embodiment, multiple battery units are connected in parallel. Each battery unit in the energy storage device can be charged and discharged. By controlling the charging and discharging of each battery unit, large-scale energy storage and release can be achieved. The battery unit is a whole formed by connecting multiple battery packs together. Exemplarily, a single battery unit can be obtained by connecting multiple battery packs in series, parallel, or a combination of series and parallel connections.

[0068] In the embodiments of this application, the battery device may include a battery cabinet or a battery cluster. For example, a battery device includes multiple battery packs connected in series, each battery pack including multiple cells connected in series, parallel, or mixed series.

[0069] Energy storage devices may include energy storage containers, energy storage power sources, or other devices capable of storing energy. For example, Figure 1 Here are some schematic diagrams of the energy storage container structure of the embodiment system, such as Figure 1 As shown, an energy storage container can be, for example, a regular cuboid structure, where the six faces of the cuboid serve as the six outer walls of the energy storage device. Setting the energy storage device in a cuboid structure facilitates its fixed placement and transportation. Of course, the energy storage device can also have other shapes; for example, at least one wall of the energy storage device may be angled.

[0070] Figure 2 A schematic diagram of the energy storage device provided in the first embodiment is shown below. Figure 2 As shown, the energy storage device includes a bus, a primary controller, and S energy storage modules, where S is an integer greater than or equal to 2. Each energy storage module includes a battery, a secondary controller, and a switch. The secondary controller in each energy storage module can control the on / off state of the corresponding switch to control the power-on or power-off state of the corresponding battery. Each secondary controller is communicatively connected to the primary controller.

[0071] The energy storage module in this application embodiment may include an electrical cabinet, and the battery device may include a battery cluster.

[0072] In any embodiment of this application, for any energy storage module, powering on the battery device can be achieved by turning on a switch connected to the battery device, so that the battery device can transmit electrical energy; powering off the battery device can be achieved by closing a switch connected to the battery device, so that the battery device cannot transmit electrical energy.

[0073] Figure 3 A schematic diagram of the energy storage device provided in the second embodiment is shown below. Figure 3 As shown, the energy storage device includes a busbar, a primary controller, and S energy storage modules. In each of the S energy storage modules, the first energy storage module out of every T energy storage modules (… Figure 3 The diagram shows T as 2 (in other embodiments, T can be an integer greater than 2). The system includes a secondary controller. Each energy storage module includes a battery device and a switch. Each secondary controller can control the on / off state of each of the T switches, thereby controlling the power-on or power-off state of each of the T battery devices. Each secondary controller is communicatively connected to the primary controller.

[0074] Because energy storage devices require large-scale power transmission, their reliable operation is crucial, necessitating monitoring of their status.

[0075] In some solutions, energy storage devices can send their status data to a backend monitoring system, allowing the system to analyze the data and determine whether the device is operating normally or in a faulty state. However, in an area, multiple energy storage devices are often installed. Even if staff know that a specific energy storage device has a fault, they may not be able to locate it among the many devices.

[0076] In some solutions, an indicator device can be installed in the energy storage device to determine whether the energy storage device is faulty. However, this solution cannot accurately reflect the status of the energy storage device, which can easily lead to bias in the judgment of the status of the energy storage device and affect the reliable operation of the energy storage device.

[0077] To alleviate the aforementioned problems, research has found that indicator devices can be installed in energy storage devices. These devices can include at least one of the following: indicator lights, displays, digital tubes, displays, buzzers, etc. The operating status of these indicator devices within the energy storage device can be controlled based on the operating status data, working status, and overall fault level of each battery unit. This allows the operating status of the indicator devices to be acquired manually, through inspection equipment, or via cameras, thereby determining the overall state of the energy storage device and improving the accuracy of status determination.

[0078] Based on the above considerations, this application provides a status display control method for an energy storage device, which acquires the operating status data of each battery device in the energy storage device and the auxiliary operating data of the energy storage auxiliary device in the energy storage device; determines the working status data of each battery device based on the operating status data, and determines the comprehensive fault level of the energy storage device based on the auxiliary operating data and the operating status data; and controls the operating status of the indicator device in the energy storage device based on the operating status data, working status and comprehensive fault level of each battery device. By acquiring the operational status data of each battery unit and the auxiliary operational data of the energy storage auxiliary units, the core operational information of the energy storage device is fully covered, avoiding the problem of inaccurate status judgment caused by a single data source and improving the accuracy of determining the status of the energy storage device. Based on the operational status data, working status, and comprehensive fault level of each battery unit, the operational status of the indicator devices in the energy storage device is controlled. This allows the operational status of the indicator devices to be determined from the operational and working status of each battery unit, as well as from the comprehensive fault level of the energy storage device. The operational status of the indicator devices can comprehensively reflect the status of the energy storage device, rather than just reporting whether the energy storage device is operating malfunctioning. Therefore, the operational status of the energy storage device can be accurately determined based on the operational status of the indicator devices, improving the accuracy of determining the status of the energy storage device and thus improving the operational reliability of the energy storage device.

[0079] For example, each step in the status display control method for the energy storage device in this application embodiment can be applied to the primary controller in the energy storage device. The primary controller is connected to each secondary controller in the energy storage device.

[0080] It should be noted that the primary controller and secondary controller in the embodiments of this application are only for illustrating the hierarchical relationship between controllers. The secondary controller is a subordinate controller of the primary controller, and primary and secondary do not represent the actual hierarchy of controllers in the energy storage system. For example, the primary controller can be the first-level controller in the energy storage device, and the secondary controller can be the second-level controller in the energy storage device. As another example, the primary controller can be the second-level controller in the energy storage device, and the secondary controller can be the third-level controller in the energy storage device, and so on.

[0081] Figure 4 A flowchart illustrating the status display and control method for an energy storage device provided in some embodiments, such as... Figure 4 As shown, the method includes the following steps:

[0082] S401. Obtain the operating status data of each battery device in the energy storage device and the auxiliary operating data of the energy storage auxiliary device in the energy storage device.

[0083] For example, the operating status data may include at least one of the following: current data, voltage data, insulation status data, temperature data, cell voltage data, cell temperature data, etc. For example, the battery device may include multiple cells, and the operating status data of the battery device may include the operating status data of the cells, such as cell voltage data and / or cell temperature data, etc.

[0084] The operating status data of each battery unit can be sent from the corresponding secondary controller to the primary controller. Each secondary controller can obtain the operating status data of the battery unit within its respective energy storage module.

[0085] The primary controller can also connect to energy storage auxiliary devices within the energy storage unit. For example, the energy storage auxiliary device can be at least one auxiliary equipment, which may include at least one of the following: fire-fighting equipment, air conditioning, dehumidification equipment, water-cooling equipment, thermal management system, etc. The auxiliary operating data can be the operating data of the energy storage auxiliary device.

[0086] Auxiliary operation data can be sent from the energy storage auxiliary device to the primary controller.

[0087] S402. Based on the operating status data, determine the operating status of each battery device, and based on the auxiliary operating data and operating status data, determine the overall fault level of the energy storage device.

[0088] For example, the operating state may include a power-on state or a power-off state. In the embodiments of this application, power-on may include high voltage, and power-off may include low voltage.

[0089] In some embodiments, the operating status data may include first voltage data of the side of each switch connected to the battery device and second voltage data of the side of each switch connected to the busbar. The operating state of each battery device is determined based on the first and second voltage data. For example, for any given battery device, if the absolute value of the difference between the first and second voltage data is less than or equal to a first voltage threshold, the operating state of the battery device is determined to be "powered on"; if the absolute value of the difference between the first and second voltage data is greater than the first voltage threshold, the operating state of the battery device is determined to be "powered off". In other embodiments, the operating status data may include voltage data of the battery devices. The operating state of each battery device is determined based on the amount of change in the voltage data of each battery device within a preset time period. For example, for any given battery device, if the amount of change in the voltage data of the battery device within a preset time period is greater than or equal to a second voltage threshold, the operating state of the battery device is determined to be "powered on"; if the amount of change in the voltage data of the battery device within a preset time period is less than the second voltage threshold, the operating state of the battery device is determined to be "powered off".

[0090] For example, the comprehensive fault level may include the overall fault level of the energy storage device, or it may include a combination of the overall fault level of the energy storage device and the battery fault levels of each battery device. The overall fault level of the energy storage device refers to the current fault severity level of the entire energy storage device, determined by comprehensively judging the operating status data of each battery device and the auxiliary operating data of the energy storage auxiliary devices. It reflects the severity of the fault when the energy storage system as a whole is functioning normally or abnormally. The battery fault level of each battery device refers to the fault severity level determined individually based on the operating status data of each individual battery device. It characterizes the severity of the fault when that battery device is functioning normally or abnormally.

[0091] S403. Based on the operating status data of each battery device, determine the secondary controller that communicates normally with the primary controller and the acquisition module that communicates normally with each secondary controller.

[0092] Normal communication between the primary and secondary controllers indicates that the physical link, data interaction, and protocol parsing between them are all in good working order, enabling real-time and accurate command issuance and data reporting. For example, an energy storage device includes multiple secondary controllers, each communicatively connected to the primary controller. However, during the operation of the energy storage device, communication anomalies may occur between one or more secondary controllers and the primary controller, preventing the primary controller from accurately obtaining the operational status data of these secondary controllers.

[0093] The data acquisition module collects operational status data from the battery device and sends the collected data to the secondary controller. Normal communication between the secondary controller and the acquisition module indicates that the physical link, data interaction, and protocol parsing between them are functioning correctly, enabling real-time and accurate command issuance and data reporting. For example, each secondary controller in the energy storage device can be communicatively connected to multiple acquisition modules, such as at least one of the following: a cell voltage acquisition module, a battery device voltage acquisition module, a cell temperature acquisition module, and a battery device insulation acquisition module. However, during the operation of the energy storage device, communication anomalies may occur between one or more acquisition modules and the secondary controller, preventing the secondary controller from accurately obtaining the operational status data collected by these modules.

[0094] In some embodiments, for any secondary controller, when the primary controller can obtain the operating status data of the battery device from the secondary controller, it is determined that the primary controller and the secondary controller are communicating normally; when the primary controller cannot obtain the operating status data of the battery device from the secondary controller, it is determined that the primary controller and the secondary controller are communicating abnormally.

[0095] In some embodiments, for any secondary controller and any acquisition module configured to communicate with the secondary controller, when the primary controller can obtain operating status data from the acquisition module, it is determined that the secondary controller and the acquisition module are communicating normally; when the primary controller cannot obtain operating status data from the acquisition module, it is determined that the secondary controller and the acquisition module are communicating abnormally.

[0096] S404. Control the operating status of the energy storage indicator device according to the working status of each battery device, the overall fault level, and the secondary controller that is in normal communication with the primary controller.

[0097] In some embodiments, when the overall fault level indicates that there is no fault in the energy storage device and all secondary controllers are communicating normally with the primary controller, the operating state of the energy storage indicator is controlled as a first indicator state; when the overall fault level indicates that there is a fault in the energy storage device and / or at least one secondary controller is communicating abnormally with the primary controller, if the operating state of each battery device is a power-off state, the operating state of the energy storage indicator is controlled as a second indicator state; if the operating state of at least one battery device is a power-on state, the operating state of the energy storage indicator is controlled as a third indicator state.

[0098] S405. Based on the operating status of each battery device, the battery fault level of each battery device in the comprehensive fault level, and the acquisition module that communicates normally with each secondary controller, control the operating status of each module indicator device.

[0099] For example, the energy storage indicator may be disposed on the outer surface of the energy storage device. For example, the module indicator may be disposed on the outer surface of the energy storage device, or correspondingly disposed on the outer surface of the energy storage module.

[0100] The status of an energy storage device can be indicated by the operating status of its indicator devices. For example, the indicator devices can include various indicator devices of different colors, and the status of the energy storage device can be indicated by controlling the operating status of each indicator device.

[0101] In some embodiments, for each energy storage module, when the battery fault level of the battery device in the energy storage module indicates that there is no fault in the battery device and the acquisition modules in the energy storage module are all communicating normally with the secondary controller, the operating state of the module indicator device on the energy storage module is controlled to be a first indicator state; when the battery fault level of the battery device in the energy storage module indicates that there is a fault in the battery device, and / or, at least one acquisition module in the energy storage module is communicating abnormally with the secondary controller, if the battery device in the energy storage module is in a power-off state, the operating state of the control module indicator device is controlled to be a second indicator state; if the battery device in the energy storage module is in a power-on state, the operating state of the control module indicator device is controlled to be a third indicator state.

[0102] For example, the first indication state, the second indication state, and the third indication state are different. Taking an indicator device including an indicator light as an example, any one of the first, second, and third indication states may include constantly lit, flashing, or constantly off. It should be noted that this application embodiment uses an indicator light as an example for description. In other embodiments, the indicator device may include a combination of an indicator light and other indicator devices, or it may include other indicator devices, and the implementation is similar to that of this application embodiment, which will not be described in detail here.

[0103] In some embodiments, based on the operating status of each battery device, the battery fault level of each battery device in the comprehensive fault level, and the acquisition module that communicates normally with each secondary controller, each indication instruction can be sent to each secondary controller. Each indication instruction indicates the operating status of each module indication device, and each indication instruction is used by the secondary controller to control the operating status of each module indication device.

[0104] The technical solution provided in this application embodiment achieves full coverage of the core operating information of the energy storage device by acquiring the operating status data of each battery device and the auxiliary operating data of the energy storage auxiliary device. This avoids the problem of inaccurate status judgment caused by a single data source and improves the accuracy of determining the status of the energy storage device. Based on the operating status data, working status, and comprehensive fault level of each battery device, the operating status of the indicator device in the energy storage device is controlled. This allows the operating status of the indicator device to be determined from the operating status and working status of each battery device, as well as from the comprehensive fault level of the energy storage device, so that the operating status of the indicator device can comprehensively reflect the status of the energy storage device. Instead of simply reporting whether the energy storage device is malfunctioning, this system accurately determines the energy storage device's status based on the operating status of the indicator devices, improving the accuracy of the determined status and thus enhancing the device's operational reliability. Furthermore, by controlling the operating status of the energy storage indicator devices and the indicator devices of each module, a hierarchical control scheme for the indicator device's operating status is constructed. This enables precise differentiation and display of the overall and partial status of the energy storage device, effectively solving the technical problem of difficulty in accurately judging the energy storage device's status due to mixed display of overall and partial statuses. Therefore, it improves the accuracy and intuitiveness of the energy storage device's status display.

[0105] The following describes a feasible implementation of S404: The energy storage indicator includes a first display device, a second display device, and a third display device; the operating status of the energy storage indicator is controlled according to the operating status of each battery device, the overall fault level, and the second-level controller that is in normal communication with the first-level controller, including: controlling the operating status of the first display device according to the operating status of each battery device; controlling the operating status of the second display device according to the overall fault level; and controlling the operating status of the third display device according to the second-level controller that is in normal communication with the first-level controller.

[0106] In some embodiments, the first display device, the second display device, and the third display device may be provided separately. In other embodiments, the first display device, the second display device, and the third display device may be integrated into a single device.

[0107] For example, the first display device may include a first indicator light, the second display device may include a second indicator light, and the third display device may include a third indicator light. For example, the first indicator light may emit light of a first color, the second indicator light may emit light of a second color, and the third indicator light may emit light of a third color.

[0108] In this embodiment, the first color, the second color, and the third color are different. For example, the first color can be red, the second color can be yellow, and the third color can be green. In other embodiments, the first color, the second color, and the third color can be other colors, and this embodiment does not limit this.

[0109] In this embodiment of the application, each indicator device in the first to sixth display devices may include a single indicator light or multiple indicator lights, and the multiple indicator lights may be arranged in a row.

[0110] In some embodiments, the number of battery devices in the powered-on state can be determined based on the operating state of each battery device, and the operating state of the first display device can be controlled based on the number of battery devices in the powered-on state.

[0111] In some embodiments, the operating status of the second display device is controlled according to whether the overall fault level of the energy storage device in the comprehensive fault level belongs to the first fault level, the second fault level, or the third fault level.

[0112] In some embodiments, the operating state of the third display device is controlled according to the number of secondary controllers that are in normal communication with the primary controller.

[0113] In the technical solution provided in this application embodiment, the energy storage indicator device is divided into three types of display devices. The operating status of the first display device is controlled according to the working status of each battery device, the operating status of the second display device is controlled according to the comprehensive fault level, and the operating status of the third display device is controlled according to the second-level controller that is in normal communication with the first-level controller. In this way, the working status, comprehensive fault level, and communication topology status of the battery device are independently displayed at the physical level. This effectively solves the technical problem of information confusion and identification difficulties caused by multiple status information superimposed on a single indicator device. It is beneficial to intuitively obtain the corresponding dimension status information at the energy storage device level through different display devices, thereby improving the accuracy and intuitiveness of the energy storage device status display.

[0114] To achieve the scheme of controlling the operating state of the first display device, the following feasible implementation methods can be provided: In some embodiments, controlling the operating state of the first display device in the energy storage indicator device according to the operating state of each battery device includes: when the first display device includes a single display device, determining the number of battery devices powered on in the energy storage device according to the operating state of each battery device, and controlling the operating state of the first display device according to the number of battery devices powered on and the total number of battery devices in the energy storage device. In some embodiments, controlling the operating state of the first display device according to the operating state of each battery device includes: when the first display device includes a first main display device and each first slave display device that indicates the state of each battery device in the energy storage device, determining the power-on state of the energy storage device and the power-on state of each battery device according to the operating state of each battery device; controlling the operating state of the first main display device according to the power-on state of the energy storage device, and controlling the operating state of each first slave display device according to the power-on state of each battery device.

[0115] In some embodiments, when the number of battery devices powered on in the energy storage device is less than or equal to a first quantity threshold, the first display device is controlled to operate in a first operating state; when the number of battery devices powered on in the energy storage device is greater than the first quantity threshold but less than the total number of battery devices in the energy storage device, the first display device is controlled to operate in a second operating state; and when the number of battery devices powered on in the energy storage device is equal to the total number of battery devices in the energy storage device, the first display device is controlled to operate in a third operating state.

[0116] For example, the first quantity threshold can be an integer greater than or equal to 0. For instance, the first quantity threshold can be 0.

[0117] For example, the first operating state can be always off, the second operating state can be flashing, and the third operating state can be always on. In other embodiments, the first to third operating states can be other states, and this application does not limit them.

[0118] The first master display device can be used to indicate the overall operating status of the energy storage device, and each first slave display device can be used to indicate the operating status of each battery device. For example, the number of first slave display devices can be the same as the number of battery devices in the energy storage device, so that each first slave display device can indicate the operating status of one battery device.

[0119] In some embodiments, if the number of battery devices in the energy storage device that are in the powered-on state is greater than or equal to a preset number, the operating state of the energy storage device is determined to be the powered-on state; if the number of battery devices in the energy storage device that are in the powered-on state is less than the preset number, the operating state of the energy storage device is determined to be the powered-off state.

[0120] For example, when the energy storage device is in a power-off state, the operating state of the first main display device is controlled to be a first operating state; when the energy storage device is in a power-on state, the operating state of the first main display device is controlled to be a third operating state.

[0121] For example, for any battery device, when the battery device is in a power-off state, the corresponding first slave display device is controlled to operate in a first operating state; when the battery device is in a power-on state, the corresponding first slave display device is controlled to operate in a third operating state.

[0122] The technical solution provided in this application provides two parallel implementation methods for the first display device. It can control the operating status of the first display device when it includes a single display device, or it can coordinate the operating status of the first main display device and each first slave display device when the first display device includes a first main display device and each first slave display device. In this way, a flexible control scheme compatible with different hardware configurations is constructed, which effectively solves the technical problem that it is difficult to accurately control due to different configurations of indicator devices caused by differences in the scale of energy storage devices or cost constraints. It can select the appropriate indicator mode according to the actual application scenario, thereby improving the universality and configuration flexibility of the energy storage device status indicator scheme.

[0123] To achieve a scheme for controlling the operating state of the second display device, the following feasible implementation methods can be provided: In some embodiments, controlling the operating state of the second display device according to the overall fault level includes: when the second display device includes a single display device, controlling the operating state of the second display device according to the overall fault level of the energy storage device in the overall fault level. In some embodiments, controlling the operating state of the second display device according to the overall fault level includes: when the second display device includes a second main display device and each second slave display device indicating the state of each battery device in the energy storage device, controlling the operating state of the second main display device according to the overall fault level of the energy storage device in the overall fault level, and controlling the operating state of each second slave display device according to the battery fault level of each battery device in the overall fault level.

[0124] In some implementations, when the overall fault level of the energy storage device is a first fault level, the operating state of the second display device is controlled to a first operating state; when the overall fault level of the energy storage device is a second fault level, the operating state of the second display device is controlled to a second operating state; and when the overall fault level of the energy storage device is a third fault level, the operating state of the second display device is controlled to a third operating state.

[0125] The second master display device can be used to indicate the overall fault status of the energy storage device, and each second slave display device can be used to indicate the fault status of each battery device. For example, the number of second slave display devices can be the same as the number of battery devices in the energy storage device, so that each second slave display device can indicate the operating status of one battery device.

[0126] In some implementations, when the overall fault level of the energy storage device is a first fault level, the operating state of the second main display device is controlled to a first operating state; when the overall fault level of the energy storage device is a second fault level, the operating state of the second main display device is controlled to a second operating state; and when the overall fault level of the energy storage device is a third fault level, the operating state of the second main display device is controlled to a third operating state.

[0127] In some implementations, for any battery device, if the battery failure level of the battery device is a first failure level, the corresponding second slave display device is controlled to operate in a first operating state; if the battery failure level of the battery device is a second failure level, the corresponding second slave display device is controlled to operate in a second operating state; if the battery failure level of the battery device is a third failure level, the corresponding second slave display device is controlled to operate in a third operating state.

[0128] The technical solution provided in this application provides two parallel implementation methods for the second display device. One method controls the operating status of the second display device when it includes a single display device, while the other method coordinates the operating status of the second main display device and each second slave display device when the second display device includes a second main display device and several second slave display devices. This achieves hierarchical differentiation between the overall fault level of the energy storage device and the fault levels of each battery device, effectively solving the technical problem of being unable to distinguish between overall and local faults due to fault level information being aggregated in a single indicator device. Furthermore, it allows for flexible selection of the granularity of fault information presentation based on hardware configuration, thereby improving the versatility and configuration flexibility of the energy storage device status indication scheme.

[0129] To implement a scheme for controlling the operating state of a third display device, the following feasible implementation methods can be provided: In some embodiments, controlling the operating state of the third display device based on a secondary controller that communicates normally with the primary controller includes: when the third display device comprises a single display device, controlling the operating state of the third display device based on the number of secondary controllers that communicate normally with the primary controller and the total number of secondary controllers in the energy storage device. In some embodiments, controlling the operating state of the third display device based on a secondary controller that communicates normally with the primary controller includes: when the third display device comprises a third main display device and each third slave display device that indicates the state of each battery device in the energy storage device, controlling the operating state of the third main display device based on the number of secondary controllers that communicate normally with the primary controller and the total number of secondary controllers in the energy storage device, and controlling the operating state of each third slave display device based on the identifier of the secondary controller that communicates normally with the primary controller.

[0130] In some embodiments, when the number of secondary controllers communicating normally with the primary controller is less than or equal to a first quantity threshold, the operating state of the third display device is controlled to be a first operating state; when the number of secondary controllers communicating normally with the primary controller is greater than the first quantity threshold and less than or equal to a second quantity threshold, the operating state of the third display device is controlled to be a second operating state; when the number of secondary controllers communicating normally with the primary controller is greater than the second quantity threshold, the operating state of the third display device is controlled to be a third operating state.

[0131] The third master display device can be used to indicate the overall communication status between the primary controller and the secondary controller, while each third slave display device can be used to indicate the communication status between each secondary controller and the primary controller. The communication status can include normal or abnormal communication status. For example, the number of third slave display devices can be the same as the number of battery devices in the energy storage device, so that each third slave display device can indicate whether the primary controller can obtain the operating status data of a corresponding battery device.

[0132] In some implementations, when the number of secondary controllers communicating normally with the primary controller is less than or equal to a first quantity threshold, the third main display device is controlled to operate in a first operating state; when the number of secondary controllers communicating normally with the primary controller is greater than the first quantity threshold and less than or equal to a second quantity threshold, the third main display device is controlled to operate in a second operating state; and when the number of secondary controllers communicating normally with the primary controller is greater than the second quantity threshold, the third main display device is controlled to operate in a third operating state.

[0133] In some implementations, the identifier of the battery device to which the primary controller can obtain operating status data is determined based on the identifier of the secondary controller that communicates normally with the primary controller; the operating status of each third slave display device is controlled according to the identifier of the battery device. For example, for any battery device, if the primary controller cannot obtain the operating status data of the battery device, the operating status of the corresponding third slave display device is controlled to a first operating state; if the primary controller can obtain the operating status data of the battery device, the operating status of the corresponding third slave display device is controlled to a third operating state.

[0134] The technical solution provided in this application provides two parallel implementation methods for the third display device. It can control the operating status of the third display device when it includes a single display device, or it can coordinate the operating status of the third main display device and each third slave display device when the third display device includes a third main display device and each third slave display device. In this way, the overall status of the communication topology and the online status of each secondary controller are displayed in a coordinated manner. This effectively solves the technical problem that the specific offline battery device cannot be located because the communication status information is aggregated on a single indicator device. It can flexibly select the granularity of the communication status presentation according to the hardware configuration, thereby improving the accuracy and location of the communication topology status indication.

[0135] The following describes a feasible implementation of S405: Based on the operating status of each battery device, the battery fault level of each battery device in the comprehensive fault level, and the acquisition module that communicates normally with each secondary controller, the operating status of each module indicator device is controlled, including: for each secondary controller, based on the operating status of the battery device managed by the secondary controller, the operating status of the fourth display device in the module indicator device on the energy storage module to which the secondary controller belongs is controlled; based on the battery fault level of the battery device managed by the secondary controller in the comprehensive fault level, the operating status of the fifth display device in the module indicator device on the energy storage module to which the secondary controller belongs is controlled; based on the acquisition module that communicates normally with the secondary controller, the operating status of the sixth display device in the module indicator device on the energy storage module to which the secondary controller belongs is controlled.

[0136] In some embodiments, the fourth, fifth, and sixth display devices may be provided separately for each module indicator device. In other embodiments, the fourth, fifth, and sixth display devices may be integrated into a single device for each module indicator device.

[0137] For example, the fourth display device may include a fourth indicator light, the fifth display device may include a fifth indicator light, and the sixth display device may include a sixth indicator light. For example, the fourth indicator light may emit light of a first color, the fifth indicator light may emit light of a second color, and the sixth indicator light may emit light of a third color.

[0138] In the technical solution provided in this application embodiment, the module indicator device on the energy storage module is further divided into three types of display devices. For each secondary controller, the operating status of the fourth display device is controlled according to the working status of the battery device it manages, the operating status of the fifth display device is controlled according to the battery fault level of the battery device, and the operating status of the sixth display device is controlled according to the acquisition module that communicates normally with the secondary controller. In this way, the battery working status, battery fault level, and acquisition module communication status are displayed independently at the physical level. This effectively solves the technical problem of status confusion and difficulty in identification caused by the superposition of multiple status information inside the module on a single indicator device. It is beneficial to intuitively obtain the corresponding dimension status information at the energy storage module level through different display devices, thereby improving the accuracy and intuitiveness of the energy storage module status display.

[0139] To achieve a scheme for controlling the operating state of the fourth display device on the energy storage module to which the secondary controller belongs, the following feasible implementation methods can be provided: In some embodiments, controlling the operating state of the fourth display device on the energy storage module to which the secondary controller belongs, based on the operating state of the battery devices managed by the secondary controller, includes: when the fourth display device includes a single display device, determining the number of battery devices managed by the secondary controller that are powered on based on the operating state of the battery devices managed by the secondary controller; and controlling the operating state of the fourth display device based on the number of battery devices powered on and the total number of battery devices managed by the secondary controller. In some embodiments, controlling the operating state of the fourth display device on the energy storage module to which the secondary controller belongs, based on the operating state of the battery devices managed by the secondary controller, includes: when the fourth display device includes multiple first sub-display devices, each first sub-display device indicating a battery device managed by the secondary controller, determining the identifier of the powered-on battery device among the battery devices managed by the secondary controller based on the operating state of the battery devices managed by the secondary controller; and controlling the operating state of each first sub-display device based on the identifier of the powered-on battery device.

[0140] In some embodiments, if the number of battery devices managed by the secondary controller is 1, when the battery devices managed by the secondary controller are in a powered-on state, the operating state of the fourth display device is controlled to be a first operating state; when the battery devices managed by the secondary controller are in a powered-off state, the operating state of the fourth display device is controlled to be a third operating state.

[0141] In some embodiments, if the number of battery devices managed by the secondary controller is greater than 1, and the number of battery devices powered on by the secondary controller is less than or equal to a first quantity threshold, the fourth display device is controlled to operate in a first operating state; if the number of battery devices powered on by the secondary controller is greater than the first quantity threshold but less than the total number of battery devices managed by the secondary controller, the fourth display device is controlled to operate in a second operating state; and if the number of battery devices powered on by the secondary controller is equal to the total number of battery devices managed by the secondary controller, the fourth display device is controlled to operate in a third operating state.

[0142] In some embodiments, the operating state of the first sub-display device corresponding to the battery device in the powered-on state can be controlled to a first operating state; the operating state of the first sub-display device corresponding to the battery device in the powered-off state can be controlled to a third operating state.

[0143] In this embodiment of the application, the primary controller can send the operating status indication information of the indication device to the secondary controller, so that the secondary controller can control the operating status of at least one of the fourth display device, the fifth display device, and the sixth display device according to the operating status indication information of the indication device.

[0144] The technical solution provided in this application provides two parallel implementation methods for the fourth display device. It can control the operating status of the fourth display device when it includes a single display device, or it can control the operating status of multiple first sub-display devices when the fourth display device includes multiple first sub-display devices. In this way, a flexible control scheme compatible with different indication granularities is constructed, which effectively solves the technical problem that it is difficult to accurately control due to different configurations of indication devices caused by differences in the scale of energy storage modules. Thus, the appropriate indication mode can be selected according to the actual application scenario, thereby improving the versatility and configuration flexibility of the energy storage module status indication scheme.

[0145] To achieve a scheme for controlling the operating state of a fifth display device on an energy storage module belonging to a secondary controller, the following feasible implementation methods can be provided: In some embodiments, controlling the operating state of the fifth display device on the energy storage module belonging to a secondary controller based on the battery fault level of the battery device managed by the secondary controller in the comprehensive fault level includes: when the fifth display device is a single display device, controlling the operating state of the fifth display device based on the maximum fault level among the battery fault levels of the battery device managed by the secondary controller. In some embodiments, controlling the operating state of the fifth display device on the energy storage module belonging to a secondary controller based on the battery fault level of the battery device managed by the secondary controller in the comprehensive fault level includes: when the fifth display device includes multiple second sub-display devices, each second sub-display device indicating a respective battery fault level, controlling the operating state of each second sub-display device based on the battery fault level of the battery device managed by the secondary controller.

[0146] In some implementations, when the maximum fault level among the battery fault levels of the battery device managed by the secondary controller is the first fault level, the operating state of the fifth display device is controlled to be the first operating state; when the maximum fault level among the battery fault levels of the battery device managed by the secondary controller is the second fault level, the operating state of the fifth display device is controlled to be the second operating state; and when the maximum fault level among the battery fault levels of the battery device managed by the secondary controller is the third fault level, the operating state of the fifth display device is controlled to be the third operating state.

[0147] Each second sub-display device on a single energy storage module corresponds one-to-one with a battery device managed by a secondary controller within that energy storage module. In some embodiments, for any battery device managed by the secondary controller, if the battery fault level of that battery device is a first fault level, the operating state of the corresponding second sub-display device is determined to be a first operating state; if the battery fault level of that battery device is a second fault level, the operating state of the corresponding second sub-display device is determined to be a second operating state; and if the battery fault level of that battery device is a third fault level, the operating state of the corresponding second sub-display device is determined to be a third operating state.

[0148] The technical solution provided in this application provides two parallel implementation methods for the fifth display device. It can control the operating status of the fifth display device when it is a single display device, or it can control the operating status of each second sub-display device when the fifth display device includes multiple second sub-display devices. In this way, a flexible control scheme compatible with different fault presentation granularities is constructed, which effectively solves the technical problem that the specific fault conditions of each battery device under the jurisdiction of the secondary controller cannot be distinguished because fault level information is aggregated into a single indicator device. It can select the appropriate fault presentation mode according to the actual application scenario, thereby improving the versatility and configuration flexibility of the energy storage module fault indication scheme.

[0149] To achieve a scheme for controlling the operating state of the sixth display device on the energy storage module belonging to the secondary controller, the following feasible implementation methods can be provided: In some embodiments, controlling the operating state of the sixth display device on the energy storage module belonging to the secondary controller according to the acquisition module that normally communicates with the secondary controller includes: when the sixth display device is a single display device, controlling the operating state of the sixth display device according to the number of acquisition modules that normally communicate with the secondary controller and the total number of acquisition modules under the secondary controller. In some embodiments, controlling the operating state of the sixth display device on the energy storage module belonging to the secondary controller according to the acquisition module that normally communicates with the secondary controller includes: when the sixth display device includes multiple third sub-display devices, each of which indicates the status of each acquisition module under the secondary controller, controlling the operating state of each third sub-display device according to the identifier of the acquisition module that normally communicates with the secondary controller.

[0150] In some implementations, if the number of battery devices managed by the secondary controller is 1, and the number of acquisition modules that are normally communicating with the secondary controller is less than or equal to a first quantity threshold, it indicates that the power supply of the secondary controller is abnormal, and the operating state of the sixth display device is controlled to the first operating state; if the number of acquisition modules that are normally communicating with the secondary controller is greater than the first quantity threshold, it indicates that the power supply of the secondary controller is normal, and the operating state of the sixth display device is controlled to the third operating state.

[0151] In some embodiments, if the number of battery devices managed by the secondary controller is greater than 1, and the number of acquisition modules that communicate normally with the secondary controller is less than or equal to a first quantity threshold, it indicates that the power supply of the secondary controller is abnormal, and the operating state of the sixth display device is controlled to the first operating state; if the number of acquisition modules that communicate normally with the secondary controller is greater than the first quantity threshold and less than the total number of acquisition modules under the secondary controller, it indicates that the power supply of the secondary controller is normal but the communication with the acquisition modules is abnormal, and the operating state of the sixth display device is controlled to the second operating state; if the number of acquisition modules that communicate normally with the secondary controller is equal to the total number of acquisition modules under the secondary controller, it indicates that the power supply of the secondary controller is normal and the communication with the acquisition modules is normal, and the operating state of the sixth display device is controlled to the third operating state.

[0152] Each third sub-display device on a single energy storage module corresponds one-to-one with a data acquisition module under the secondary controller within that energy storage module. In some embodiments, for any data acquisition module managed by the secondary controller, if the data acquisition module experiences abnormal communication with the secondary controller, the operating state of the third sub-display device corresponding to that data acquisition module is controlled to a first operating state; if the data acquisition module communicates normally with the secondary controller, the operating state of the third sub-display device corresponding to that data acquisition module is controlled to a third operating state.

[0153] The technical solution provided in this application provides two parallel implementation methods for the sixth display device. This allows control of the operating state of the sixth display device when it is a single display device, and also allows control of the operating state of multiple third sub-display devices when the sixth display device includes multiple third sub-display devices. This constructs a flexible control scheme compatible with different communication state presentation granularities, effectively solving the technical problem of being unable to locate specific offline acquisition modules due to the aggregation of communication state information from acquisition modules onto a single indicator device. It allows selection of an appropriate communication state presentation mode based on the actual application scenario, thereby improving the versatility and locatability of the acquisition module communication state indication scheme.

[0154] To accurately determine the operating status of each battery device, the following embodiment is provided: Each battery device is connected to a bus via a switch, and the operating status data includes first voltage data at the end of each switch connected to the battery device and second voltage data at the end of each switch connected to the bus. Determining the operating status of each battery device based on the operating status data includes: determining the operating status of each battery device based on the first voltage data at the end of each switch connected to the battery device and the second voltage data at the end of each switch connected to the bus.

[0155] For example, Figure 5A flowchart illustrating a method for determining the operating state of each battery device based on operating state data, as provided in some embodiments, is shown below. Figure 5 As shown, the method includes the following steps:

[0156] S501. Obtain the first voltage data of the end of each switch connected to the battery device and the second voltage data of the end of each switch connected to the busbar from the operating status data.

[0157] S502. Determine the operating status of each battery device based on the first voltage data of the end of each switch connected to the battery device and the second voltage data of the end of each switch connected to the bus.

[0158] For example, the first voltage data and the second voltage data can be the voltage data across the positive switch.

[0159] In some embodiments, for any battery device, if the absolute value of the difference between the first voltage data and the second voltage data is less than or equal to a first voltage threshold, the operating state of the battery device is determined to be powered on; if the absolute value of the difference between the first voltage data and the second voltage is greater than the first voltage threshold, the operating state of the battery device is determined to be powered off.

[0160] In the technical solution provided in this application embodiment, the working state of each battery device is determined based on the first voltage data of the end of each switch connected to the battery device and the second voltage data of the end of each switch connected to the bus. Thus, the working state of each battery device can be determined without waiting for data accumulation, reducing the phenomenon of lag in the determination of the working state of each battery device and improving the accuracy of the determination of the working state of each battery device.

[0161] Figure 6 A flowchart illustrating a method for determining the overall fault level of an energy storage device based on auxiliary operating data and operating status data, provided in some embodiments, is shown below. The operating status data includes the voltage data of each cell in each battery device, such as... Figure 6 As shown, the method includes the following steps:

[0162] S601. For each battery device, determine the battery fault level of the battery device based on the voltage data of each cell in the battery device.

[0163] In some embodiments, temperature data of each cell in each battery device can be acquired, and for each battery device, the battery fault level of the battery device can be determined based on the voltage and temperature data of each cell in the battery device.

[0164] In some embodiments, the maximum and minimum allowable voltage data of the battery cells can be obtained, and the battery fault level of the battery device can be determined based on the voltage data of each cell in the battery device, the maximum allowable voltage data, and the minimum allowable voltage data. For example, if the voltage data of each cell in the battery device is within the voltage range from the minimum allowable voltage data to the maximum allowable voltage data, the battery fault level of the battery device is level 0, indicating that the battery device is not faulty. For example, if the voltage data of at least one cell in the battery device is not within the voltage range, the battery fault level of the battery device is determined based on the number of cells not within the voltage range, and / or based on the absolute value of the difference between the voltage data of the cells not within the voltage range and the critical voltage data (maximum allowable voltage data or minimum allowable voltage data).

[0165] S602. Based on the auxiliary operation data, determine the auxiliary control fault level, and based on the auxiliary control fault level and the battery fault level of each battery device, determine the overall fault level of the energy storage device.

[0166] For example, the auxiliary operation data may include the operation data of at least one auxiliary device, and the auxiliary control fault level can be determined based on the operation data of each auxiliary device. For instance, the fault level of each auxiliary device can be determined based on its operation data; and the auxiliary control fault level can be determined based on the fault levels of each auxiliary device. In some embodiments, the highest fault level among the fault levels of each auxiliary device can be determined as the auxiliary control fault level. In other embodiments, the fault weights of each auxiliary device can be obtained, and the fault levels of each auxiliary device can be weighted using these fault weights to obtain the auxiliary control fault level.

[0167] In some embodiments, the highest fault level among the auxiliary control fault level and the battery fault levels of each battery device can be used to determine the overall fault level of the energy storage device. In other embodiments, the weights corresponding to the auxiliary control fault level and the battery fault levels of each battery device can be obtained, and the auxiliary control fault level and the battery fault levels of each battery device can be weighted using the weights corresponding to the auxiliary control fault level and the battery fault levels of each battery device, respectively, to obtain the overall fault level of the energy storage device.

[0168] S603. The overall fault level of the energy storage device and the battery fault levels of each battery device are combined to determine the comprehensive fault level of the energy storage device.

[0169] In this embodiment, the overall fault level of the energy storage device includes the overall fault level of the energy storage device and the battery fault level of each battery device.

[0170] In the technical solution provided in this application embodiment, the comprehensive fault level includes the overall fault level and the battery fault level of each battery device. The overall fault level can reflect the combined fault situation of battery faults and auxiliary control faults, while the battery fault level of each battery device can reflect the fault situation of the cells inside each battery device. This realizes the hierarchical characterization of the fault state of the energy storage device, so the comprehensive fault level can accurately and comprehensively reflect the fault situation of the energy storage device, improving the accuracy and comprehensiveness of the determined fault level of the energy storage device.

[0171] The following describes a feasible implementation method for determining the battery fault level of the battery device based on the voltage data of each cell in S601: When the voltage data of each cell in the battery device is within the range of the minimum allowable voltage data to the maximum allowable voltage data, the battery fault level is determined to be the first fault level. When the maximum voltage data of each cell in the battery device is greater than the maximum allowable voltage data, if the difference between the maximum voltage data and the maximum allowable voltage data is less than or equal to a preset voltage data, the battery fault level is the second fault level; if the difference between the maximum voltage data and the maximum allowable voltage data is greater than the preset voltage data, the battery fault level is the third fault level. When the minimum voltage data of each cell in the battery device is less than the minimum allowable voltage data, if the difference between the minimum allowable voltage data and the minimum voltage data is less than or equal to a set voltage data, the battery fault level is the second fault level; if the difference between the minimum allowable voltage data and the minimum voltage data is greater than the set voltage data, the battery fault level is the third fault level.

[0172] For example, a battery fault level of 1 can indicate that the battery device is fault-free, a battery fault level of 2 can indicate that the battery device has a minor fault, and a battery fault level of 3 can indicate that the battery device has a serious fault.

[0173] For example, a battery fault level of the first fault level can indicate that the fault level of the battery device is less than or equal to the first level threshold, a battery fault level of the second fault level can indicate that the fault level of the battery device is greater than the first level threshold and less than or equal to the second level threshold, and a battery fault level of the third fault level can indicate that the fault level of the battery device is greater than the third level threshold.

[0174] In some embodiments, the preset voltage data may be the same as the set voltage data. In other embodiments, the preset voltage data may be less than or greater than the set voltage data.

[0175] In the technical solution provided in this application embodiment, the minimum allowable voltage data and the maximum allowable voltage data are used as reference thresholds. Based on whether the voltage data of each cell deviates from the reference threshold, and the comparison result of the deviation value of the voltage data of each cell relative to the reference threshold with the fixed voltage data (i.e., preset voltage data or set voltage data), the battery fault level is refined into a first fault level, a second fault level, and a third fault level. This allows for the quantitative classification of fault severity based on the magnitude of the deviation value, achieving a refined assessment of overvoltage and undervoltage faults in the battery device. This not only effectively solves the technical problem of not being able to determine the fault of the battery device at the cell level, but also effectively solves the technical problem of not being able to distinguish between minor and serious faults by simply judging whether the voltage exceeds the limit. This improves the accuracy and refinement of the determined battery fault level.

[0176] The following describes a feasible implementation method for determining the overall fault level of the energy storage device based on the auxiliary control fault level and the battery fault level of each battery device in S602: When both the auxiliary control fault level and the battery fault level of each battery device are at the first fault level, the overall fault level of the energy storage device is determined to be the first fault level; when both the auxiliary control fault level and the battery fault level of each battery device are less than or equal to the second fault level, and at least one of the auxiliary control fault level and the battery fault level of each battery device is at the second fault level, the overall fault level of the energy storage device is determined to be the second fault level; when at least one of the auxiliary control fault level and the battery fault level of each battery device is greater than the second fault level, the overall fault level of the energy storage device is determined to be the third fault level.

[0177] For example, a first-level auxiliary control fault indicates that the energy storage auxiliary device is fault-free; a second-level fault indicates a minor fault; and a third-level fault indicates a serious fault. For instance, if all auxiliary equipment in the energy storage auxiliary device is operating normally, it indicates that the energy storage auxiliary device is fault-free. For example, if the dehumidifier in the energy storage auxiliary device malfunctions, its impact on the reliable operation of the energy storage device is minor, and a minor fault can be identified. Conversely, if the fire suppression system in the energy storage device malfunctions, its impact on the reliable operation of the energy storage device is significant, and a serious fault can be identified.

[0178] The technical solution provided in this application provides a hierarchical system of first fault level, second fault level, and third fault level, which are progressively advanced. By using a step-by-step judgment logic rule to determine the overall fault level of the energy storage device, the problem of being unable to determine the overall fault level of the energy storage device is effectively solved. The overall fault level of the energy storage device can be determined by comprehensively considering the auxiliary control fault level and the battery fault level of each battery device. Therefore, the determined overall fault level of the energy storage device can accurately reflect the overall fault status of the energy storage device, thus improving the accuracy and reliability of the determined overall fault level of the energy storage device.

[0179] The following uses the example of an energy storage indicator device including an indicator light on an energy storage device (e.g., an energy storage container door), a module indicator device including an indicator light on an energy storage module (e.g., an electrical cabinet), an indicator light of red as the first color, an indicator light of yellow as the second color, and an indicator light of green as the third color to illustrate the layout of the indicator lights under different implementation methods.

For example, the indicating device on the energy storage device may be located on the door of the energy storage device, and the indicating device on the energy storage module may be located on the door of the energy storage module. Red indicator lights are identified by R, green indicator lights by G, and yellow indicator lights by Y.

The odd-numbered energy storage modules each have a single red, a single yellow, and a single green indicator light, while the even-numbered modules do not have any indicator lights. Thus, the secondary controller in the odd-numbered energy storage modules manages not only the battery devices in that module but also the battery devices in the next module. The even-numbered energy storage modules do not have a secondary controller. In this configuration, the secondary controller in the odd-numbered energy storage modules controls the operating status of the indicator devices on its respective module.

[0196] It should be noted that the above examples illustrate how a secondary controller manages two battery devices. In other embodiments, the secondary controller can manage more than two battery devices. This application does not impose any limitations on this. The schematic diagrams of the indicator devices on the energy storage device and energy storage module can be derived by referring to the above examples, and this application will not elaborate further on this.
