As a novel energy storage device, a direct-current direct-hanging type battery energy storage system is gradually developed and applied due to the fact that the direct-current direct-hanging type battery energy storage system can solve various transient and steady problems of a direct-current system. Because each submodule in the battery energy storage system is a high-voltage active system, the operation and maintenance (operation and maintenance) safety of the battery energy storage system is particularly important.

The inventor of the application notices that when a worker executes operation and maintenance related tasks in a battery energy storage system, the tasks need to be disassembled into different task steps by combining the running condition of the battery energy storage system, then the task steps are filled into a work ticket/operation ticket, and finally the tasks are executed one by one according to the listed task steps. This process needs the staff to disassemble and carry out gradually the task by man-made, and along with battery energy storage system's expansion and the promotion of capacity, the maintenance operation that has a power failure also can become complicated, appears having a power failure very easily in the executive process, the power transmission operation sequence mistake, perhaps omits operating procedure's the condition such as operating procedure, leads to battery energy storage system's fortune dimension reliability relatively poor.

In order to solve the problem of poor operation and maintenance reliability of the battery energy storage system, the applicant researches and discovers that operation steps and contents of the battery energy storage system are performed based on a certain logic principle when a worker enters the battery energy storage system to operate under different task instructions in the operation and maintenance process. Therefore, corresponding application programs can be developed in a background server of the battery energy storage system, adaptive task steps are automatically matched for different task instructions based on a certain logic principle, and a worker only needs to execute related tasks according to the task steps.

Through this kind of mode, the battery energy storage system operation and maintenance in-process, the staff only need input the task instruction, can obtain corresponding task step through backend server rapidly, and in the task execution process, also need not manually to carry out filling in of work ticket or operation ticket, can effectively improve battery energy storage system's operation and maintenance work efficiency.

Through intensive research, the operation steps executed by the current working personnel can be obtained by combining with the real-time action information of the battery energy storage system generated by the working personnel in the operation and maintenance process of the battery energy storage system, and the operation steps and the task steps acquired by the background server are combined for verification, so that the working personnel can be ensured to operate and maintain the battery energy storage system according to the task steps.

The battery energy storage operation and maintenance method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. The battery energy storage system 102 communicates with the server 104 through wired or wireless communication. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104, or may be located on the cloud or other network server. The server 104 may be implemented by an independent server or a server cluster composed of a plurality of servers. The particular type of server 104 is not exclusive and in a more detailed embodiment, the server may be implemented by a personal computer or a work machine.

The specific form of the battery energy storage system 102 is not exclusive, and in a more detailed embodiment, the battery energy storage system 102 is a high voltage direct current type battery energy storage system, and the structure thereof can be combined with fig. 2. The battery energy storage system 102 includes a plurality of containers, and the plurality of containers are connected in series to finally form a battery energy storage system 102. And inside each container, each energy storage module establishes ties each other through setting up the connecting piece (specifically can be the copper bar) on the energy storage module, is located two energy storage modules of head, then is connected with the energy storage module of head end or tail end in the adjacent container respectively through the cable.

Further, in one embodiment, the topology of the battery energy storage system 102 is as shown in fig. 3, and the overall structure thereof may be divided into a sending end converter station, a receiving end converter station and a plurality of energy storage modules connected in series in sequence. Each energy storage module specifically includes a half-bridge circuit (hereinafter referred to as a power module) formed by two Insulated Gate Bipolar Transistors (IGBTs) connected in series, a filter capacitor, a filter reactance, and a battery, and the specific structure can be seen in fig. 4.

The IGBT in the power Module is controlled to be turned on or off by a Sub-Module controller (SMC), the Battery specifically includes a Battery cluster and a Battery cluster Control System for the Battery cluster, and during the operation of the Battery energy storage System 102, a BMS (Battery Management unit) in the Battery cluster Control System can collect current and voltage signals of the Battery cluster to Control the on or off of a high-voltage direct-current relay of the Battery cluster Control System. The BMS and the SMC are communicated by means of optical fibers and managed by the SMC, and can receive commands of the SMC and upload information of the battery to the SMC. The SMC is further communicatively connected to the backend server 104, and receives the relevant information from the backend server 104 and uploads the relevant information of the battery energy storage system 102 collected by the BMS and the like to the backend server 104.

It can be understood that the battery cluster comprises a plurality of battery cells, and the battery cells are connected in series and/or in parallel to form the battery cluster. The cells in the battery cluster may be of the same type or different types, for example, in a more detailed embodiment, lithium cells may be used. Further, in one embodiment, the cells in the battery cluster are all lithium iron phosphate cells.

In one embodiment, as shown in fig. 5, a method for maintaining a battery energy storage system is provided, which is described by taking the method as an example for being applied to the server in fig. 1, and includes

steps

502, 504 and 506.

And 502, acquiring a task instruction and state parameters of the battery energy storage system, and analyzing according to the task instruction and the state parameters to obtain target task step information.

Specifically, the task instruction is information related to a task that needs to be executed by the battery energy storage system in the operation and maintenance process. The state parameters are parameters related to the operation state in the operation process of the battery energy storage system and parameters of the system. The target task step information is finally determined information related to the step sequence of operating the battery energy storage system when the operation task corresponding to the task instruction is realized.

It should be noted that the task instruction is not necessarily obtained exclusively, and in one embodiment, the worker may directly interact with the server (for example, when the server is a personal computer or a work machine), and may directly input the task instruction to the server by interacting with the server when the worker has a requirement related to the operation and maintenance work in the multi-battery energy storage system.

In another embodiment, the task instruction may also be sent to the server by the staff through the portable terminal device. In the scheme of the embodiment, the server is in communication with the battery energy storage system and the terminal device, when a worker needs to operate and maintain the battery energy storage system, a task instruction needs to be sent to the server through the terminal device, and after the server receives the task instruction sent by the worker, the server starts and executes a subsequent operation and maintenance method of the battery energy storage system.

The state parameters of the battery energy storage system are obtained in a non-unique manner, and the state parameters of different types can be obtained in different manners. In one embodiment, if the state parameter is a parameter related to an operation state of the battery energy storage system during operation, for example, an energization state of a container in the battery energy storage system, whether a door of the container is opened, and voltage and current data of an energy storage module, the state parameter will change along with the operation of the battery energy storage system. Therefore, for this type of status parameters, it is necessary to collect them in real time by an external device and send them to the server.

If the state parameters are the parameters of the system, the parameters of the system are determined after the battery energy storage system is built, and the parameters cannot be changed along with the operation of the battery energy storage system, such as the number of containers in the battery energy storage system, the number of energy storage modules in each container, the number of the energy storage modules in each container, and the like. Therefore, the state parameters of the type can be stored in the server in the form of preset parameters, and when the server has a use requirement, the state parameters can be directly called.

It can be understood that the server obtains the task instruction and the state parameter, and the two obtaining actions may be performed simultaneously or sequentially, and may be selected according to actual requirements, which is not limited specifically.

After the server obtains the task instruction and the state parameters of the battery energy storage system, the server analyzes the step information, namely the target task step information, required to operate the battery energy storage system to complete the task corresponding to the task instruction by combining the task to be executed and the state parameters.

And step 504, acquiring real-time action information of the battery energy storage system.

Specifically, the real-time action information is an action signal generated when the battery energy storage system is caused to act when the worker works on the battery energy storage system, and is used for representing the operation (or step) performed by the worker in the battery energy storage system. After the server acquires the real-time action information, the server analyzes the information, and then can know what operation is performed by a current worker in the battery energy storage system, such as opening a door of a certain container.

It can be understood that, according to different operation steps of a worker on the battery energy storage system, corresponding real-time action information may also be different. For example, in one embodiment, when the staff performs the steps of: and opening the door of the container, wherein the corresponding real-time action information is the information of opening the door of a certain container.

It should be noted that the manner of acquiring the real-time action information by the server is not unique, and in one embodiment, the real-time action information may be obtained by detecting each detecting device arranged in the battery energy storage system, and then collectively sent to the sub-module controller, and finally fed back to the server by the sub-module controller. For example, parameters such as voltage and current in the operation process of the energy storage module and the operation state of the submodule relay (namely the high-voltage direct-current relay) can be acquired through the battery BMS, and then the parameters are sent to the submodule controller, and finally the parameters are reported to the server through the submodule controller.

Step 506, checking whether to execute operation and maintenance according to the target task step information according to the real-time action information and the target task step information.

Specifically, after the server acquires the operation content of the staff on the battery energy storage system, that is, the real-time action information of the battery energy storage system, the server analyzes whether the operation of the staff on the battery energy storage system meets the requirement of the target task step information or not by combining the target task step information and the real-time action information, that is, checks whether the staff executes the corresponding operation and maintenance action according to the target task step information or not.

Referring to fig. 6, in some embodiments, after step 506, the method further includes step 602.

Step 602, if the operation and maintenance are not executed according to the step information of the target task, the anti-misoperation lockout is triggered,

specifically, the misoperation prevention locking also prevents the misoperation of a worker, and locks the battery energy storage system. When the server checks according to the real-time action information and the target task step information, if the result of checking shows that the staff does not execute corresponding operation and maintenance operation according to the target task step information, the server triggers the anti-misoperation lock.

It can be understood that the implementation manner of triggering the false locking prevention is not unique, and in one embodiment, the control signal for locking the battery energy storage system may be generated by triggering, and at this time, the device or the device at the response position of the energy storage system may be stopped by only sending such a control signal to the corresponding position of the battery energy storage system. In another embodiment, the trigger anti-misoperation lock can also trigger the generation of prompt information of the anti-misoperation lock, and the prompt information is output to inform the staff, so that the staff is prevented from continuing to execute operation and maintenance on the battery energy storage system. The specific mode can be selected in different ways by combining with the actual scene.

According to the scheme, when the operation and maintenance are not executed according to the target task step information by the staff in the verification, the anti-misoperation lockout can be further triggered, so that the staff is prevented from continuing to execute the operation and maintenance task, unnecessary risks are caused, and the operation and maintenance safety of the battery energy storage system is improved.

It should be noted that, in another embodiment, when the operation and maintenance of the staff is not performed according to the target task after verification, the server may also output an alarm prompt message without triggering the false locking of the battery energy storage system, and each device or apparatus in the battery energy storage system still operates according to the original operation rule. And when receiving the alarm prompt information, the working personnel determine whether to stop the operation and maintenance operation of the battery energy storage system according to the actual scene. Through this scheme, output warning prompt message informs the staff, decides whether to stop the fortune dimension operation to battery energy storage system by the staff, also can avoid continuing fortune dimension to produce the risk to a certain extent, improves fortune dimension reliability.

Further, in other embodiments, when it is verified that the operation and maintenance are not performed by the staff according to the target task, the server can also output alarm prompt information and trigger the anti-misoperation lockout at the same time, and when the battery energy storage system is locked, the alarm prompt information is output to inform the staff that the battery energy storage system has triggered the anti-misoperation lockout.

In some embodiments, referring to FIG. 7 in combination, step 502 includes step 702 and step 704.

Step 702, acquiring a task instruction and state parameters of the battery energy storage system, and analyzing whether the task instruction meets preset checking conditions.

And 704, if the task instruction meets the preset checking condition, analyzing according to the task instruction and the state parameters to obtain target task step information.

Specifically, the preset check condition is a condition that needs to be met when the preset check condition triggers whether the operation and maintenance check operation is performed on the battery energy storage system according to the target task step information. When the staff operates and maintains the battery energy storage system, the executed tasks are various, certain tasks may be executed without limitation of task steps, and even if the execution steps are different, the operation of the battery energy storage system is not affected. In this case, it is not necessary to verify whether the worker performs the operation and maintenance according to the target task step information.

According to the scheme of the embodiment, after the server receives the task instruction sent by the worker, the server further analyzes the task instruction, judges whether the task corresponding to the current task instruction is according to the embodiment, acquires the target task step information and the real-time action information, and performs the necessity of checking whether the worker executes the operation and maintenance according to the target task information, and starts to execute the operation of analyzing according to the task instruction and the state parameter to obtain the target task step information when the task instruction meets the preset checking condition, namely when the task corresponding to the task instruction meets a certain logic condition.

According to the scheme, the server starts to analyze according to the task instruction and the state parameters after the task instruction obtained through analysis meets the preset verification condition, and operation of obtaining target task step information is obtained. When the working personnel issues the tasks which do not meet the preset checking condition types, the operation and maintenance control is carried out on the battery energy storage system according to the same method, so that the task resources are effectively saved, and the operation and maintenance reliability of the battery energy storage system is further improved.

It can be understood that the specific type of the preset check condition is not unique, in one embodiment, the preset check condition may be a preset error prevention condition, and in another embodiment, the preset check condition may also be a preset alarm prompt condition. The preset anti-misoperation condition is a preset condition which is required to be met by triggering anti-misoperation lockout analysis on the battery energy storage system; the preset alarm prompting condition is a preset condition which needs to be met by triggering alarm prompting analysis on the battery energy storage system.

Taking a preset error prevention condition as an example, after the server receives a task instruction sent by a worker, the server firstly analyzes whether the currently received task instruction meets the preset error prevention condition, so as to determine whether to start a subsequent operation and maintenance method of the battery energy storage system. If the task required to be executed currently does not meet the preset anti-misoperation condition, namely the task instruction does not meet the preset anti-misoperation condition, the real-time action information is not acquired subsequently to trigger the anti-misoperation lock. And if the task required to be executed currently meets the preset anti-error condition, the subsequent execution operation is realized according to the operation and maintenance method. By the scheme, when the staff issues the task unrelated to the anti-misoperation locking, the operation and maintenance of the battery energy storage system can be controlled according to the same method, so that the task resource is effectively saved, and the operation and maintenance reliability of the battery energy storage system is further improved.

It should be noted that the specific type of predetermined error protection condition is not exclusive, and in one more detailed embodiment, for example, the predetermined error protection condition includes at least one of no access permitted to a container during operation, no access permitted to a container outside of a blackout range, and no access permitted to personnel when switches and relays are closed. Correspondingly, when the preset anti-error condition is met, namely the task corresponding to the task instruction is executed, it is required to ensure that the container in operation is not allowed to enter, the container not in the power failure range is not allowed to enter, or personnel is not allowed to enter when the switch and the relay are closed. Taking the preset anti-error condition as an example that the container is not allowed to enter when the container is operated, if the task instruction sent by the staff is only to perform operation on the outer wall of the container, such as cleaning and the like; or the task corresponding to the task instruction needs to enter the container to operate in the container operation process, and the preset anti-error condition is not met.

Referring to fig. 8, in some embodiments, the target task step information is obtained by analyzing the task instruction and the status parameter, which includes

steps

802 and 804.

And step 802, analyzing according to the task instruction and the state parameter to obtain task step information.

And 804, optimizing the task step information to obtain target task step information.

Specifically, the task step information is operation content of the step that needs to be executed when the task corresponding to the task instruction is completed. And in an actual scene, after each step corresponding to the task step information is sequentially executed, the task corresponding to the task instruction can be completed. Aiming at the tasks corresponding to the same task instruction, one or more different task step information can be finally formed according to different execution sequences of all the tasks, and the number of the task steps contained in each task step information is not completely the same.

That is, in the solution of this embodiment, for the same task instruction, a plurality of different pieces of task step information can be obtained through analysis. However, the task step information is not exactly the same in the number of the specific task steps, and in order to efficiently implement the operation and the maintenance of the battery energy storage system, after the server obtains the task step information for the currently obtained task instruction, the server may first optimize the task step information to obtain the final target task step information.

In some embodiments, referring to fig. 9, step 802 includes step 902.

And step 902, traversing a preset task step database according to the task instruction and the state parameter to obtain task step information.

Specifically, the preset step database stores all task steps corresponding to the task instruction. In the actual operation process, after the server receives the task instruction, keyword extraction is carried out on the task instruction, the extracted keywords are matched in a preset step database, and all steps which may be executed when the task corresponding to the current task instruction is executed are obtained. And then, screening and combining the steps to finally obtain all feasible execution schemes when the task corresponding to the task instruction is completed, namely, at least one task step information.

It can be understood that, in another embodiment, clear and definite task instructions may be defined for the battery energy storage system, all task steps corresponding to each task instruction are stored in the preset step database, after the server receives the task instruction, the task instruction is directly subjected to matching analysis with the preset step database, all steps required by the task instruction are directly obtained, and then the obtained steps are subjected to screening and combining to finally obtain at least one piece of task step information.

According to the scheme, the preset step database is preset in the server, when the task step information is obtained, the corresponding task step information can be quickly matched and obtained only by inputting the task instruction, and the method has the advantage of high task step information matching speed.

In some embodiments, referring to FIG. 10, step 804 includes

steps

904 and 906.

And 904, selecting and pushing the task step information with the least steps according to the task step information.

And step 906, if receiving an acceptance instruction returned according to the task step information with the least steps, taking the task step information with the least steps as target task step information.

Specifically, the task step information with the least steps is the task step information with the least execution actions of the worker in the execution process. And the minimum number of steps is that the staff performs the minimum action in the execution process, so that the operation and maintenance efficiency is improved to a certain extent. Meanwhile, according to the scheme of the embodiment, the task step information with the minimum steps obtained by the matching analysis of the server can be pushed to the staff, specifically, the task step information can be displayed on the server, or the task step information can be notified to the staff in a pushing mode to the terminal device. In any pushing mode, after the staff knows the task step information with the fewest steps, the staff can also determine whether the task step information with the fewest steps is reasonable or not by combining the requirements of the staff and the requirements of an actual battery energy storage system, if so, a receiving instruction is returned to the server, and finally the task step information with the fewest steps is determined as the target task step information.

According to the scheme, after the task step information with the fewest steps is preferably obtained, the task step information with the fewest steps is further pushed to the working personnel, and the working personnel perform final confirmation operation, so that the reasonability of the finally obtained target task step information is ensured.

It can be understood that, in an embodiment, if the quantity of the task step information with the minimum steps is not unique, the task step information with the minimum steps may be all pushed, and then the staff selects which task step information is specifically adopted to perform operation and maintenance of the battery energy storage system.

In some embodiments, referring to fig. 11, step 904 is followed by step 112.

And 112, if a modification instruction returned according to the task step information with the least steps is received, modifying the task step information with the least steps to obtain modified task step information, and taking the modified task step information as target task step information.

Specifically, in an actual application scenario, since the task step information is generated by combining the server with a certain logic, a situation that is not in accordance with the actual application scenario or is not suitable for the current staff may occur. Therefore, after the server pushes the task step information with the fewest steps to the staff, the staff can also modify the task step information with the fewest steps according to the actual conditions of the staff and the battery energy storage system, and the modified task step information is used as the target task step information, so that more accurate target task step information is obtained.

It can be understood that the operation of modifying the task step information with the least steps by the staff may be performed at the server, may be performed at the terminal device, and finally the modified task step information is returned to the server by the terminal device. The specific modification operation is not unique, and may be modifying the content of a step, changing the order of steps, adding or deleting steps, and the like, and is not limited specifically.

In some embodiments, referring to fig. 12, after step 502, the method further includes step 122.

And step 122, pushing target task step information.

Specifically, according to the scheme of this embodiment, after the server obtains the target task step information, in order to ensure that the worker can operate and maintain the battery energy storage system according to the target task step information, the target task step information obtained through analysis needs to be pushed at this time.

It should be noted that, when the server pushes the target task step information, the pushed object is not unique, and in one embodiment, the server has a display function, and the target task step information is pushed, and may be pushed to a display position of the server for display so as to be referred by a worker. In another embodiment, the staff carries a terminal device communicating with the server, and at this time, the target task step information may also be pushed to the terminal device so as to be referred by the staff.

Further, in other embodiments, when the server pushes the target task information, the target task step information may be pushed to the battery energy storage system, and a component capable of directly or indirectly communicating with the server may be further provided, for example, a sub-module controller for controlling an IGBT of an energy storage module in the battery energy storage system, a detector for detecting whether a door of a container is opened, or the like.

It can be understood that, in an embodiment, after the server pushes the target task step information, whether the target task step information is pushed successfully is also analyzed (specifically, whether the target task step information fed back by another device is received and a signal is successfully received is analyzed), and when the target task step information is not pushed successfully, a prompt message can be output to notify a worker.

In some embodiments, referring to fig. 13, after step 602, the method further includes step 132.

And 132, if the anti-misoperation locking is triggered, controlling the battery energy storage system to enter a locking operation state.

Specifically, in the scheme of this embodiment, the preset check condition corresponds to a preset error prevention condition, and when the task instruction meets the preset error prevention condition, the action of obtaining the target task step information according to the task instruction and the state parameter analysis is triggered to be executed, and subsequently, if the check worker does not execute operation and maintenance according to the target task step information, the error prevention locking is triggered.

The misoperation prevention locking operation state is the operation state for preventing the misoperation of a worker and locking the battery energy storage system. In an actual scene, how to control the battery energy storage system to perform the locking operation state is different according to different task execution stages of the current battery energy storage system.

For example, in one embodiment, if the current staff is working outside the door of the container, the entering into the locked operation state may be closing the door of the container of the battery energy storage system. If the current worker works on the energy storage module in the container, the sub-module controller of the energy storage module can be closed when the locking operation state is entered.

Correspondingly, in another embodiment, if the anti-misoperation lockout is not triggered, it indicates that the operation performed by the worker at the battery energy storage system at this time meets the target task step information, and the worker may continue to perform subsequent operation steps at this time. That is, the server returns the operation of obtaining the real-time action information of the battery energy storage system and detects whether the subsequent operation steps executed by the staff meet the target task step information.

It can be understood that, in another embodiment, the preset verification condition may also be a preset alarm prompting condition, when the task instruction meets the preset alarm prompting condition, the action of obtaining the target task step information according to the task instruction and the state parameter analysis is triggered and executed, and if the operation and maintenance are not executed according to the target task step information after the verification is obtained, the alarm prompting information is triggered by the trigger server to remind the worker, and the misoperation-preventive locking is not required to be executed.

In some embodiments, referring to fig. 14, step 506 includes step 142 and step 144.

And 142, determining whether the current execution step is matched with the current required execution step corresponding to the target task step information according to the real-time action information.

And step 144, if the current execution step is not matched with the current required execution step, verifying that the operation and maintenance are not executed according to the target task step information. And if the current execution step is matched with the current required execution step, checking to obtain the operation and maintenance executed according to the target task step information, and returning to the operation of acquiring the real-time action information of the battery energy storage system until all steps corresponding to the target task step information are executed.

Specifically, in the scheme of the embodiment, when checking whether to execute operation and maintenance according to the target task step information, it is necessary to analyze whether the worker performs work according to the steps given by the target task step information by combining with the real-time action information of the battery energy storage system, that is, whenever the worker executes a step, it is analyzed whether the step is matched with the currently required execution step corresponding to the target task step information. And if the step information of the target task is matched with the step information of the current working staff, the current working staff can be shown to execute the working task according to the step information of the target task, and if the step information of the target task is not matched with the step information of the current working staff, the current working staff is shown not to execute the working task according to the step information of the target task.

In some embodiments, referring to fig. 15, step 142 includes step 152 and step 154.

And 152, detecting whether the sequence of the current execution steps is correct or not according to the real-time action information and the target task step information.

And step 154, if the sequence of the currently executed steps is correct, determining whether the content of the currently executed steps is consistent with the content of the currently required executed steps corresponding to the target task step information according to the real-time action information.

Specifically, if the contents are consistent, the current execution step is matched with the current required execution step. In the solution of this embodiment, when determining whether the current step corresponding to the real-time action information matches the currently required execution step corresponding to the target task step information, it is necessary that the execution order of the current step and the execution content are the same as each other. Therefore, the processor needs to check the execution sequence and the execution content of the currently executed step in turn, and only if the execution sequence and the execution content are both consistent with the currently required execution step, the currently executed step is considered to be matched with the currently required execution step. Whether the execution sequence of the steps required to be executed currently is different or the executed steps are different in content, the steps required to be executed currently are not matched with the steps required to be executed currently, and at the moment, the result that the operation and maintenance are not executed by the staff according to the target task step information is verified.

In one embodiment, the task corresponding to the task instruction is used for converting the operation of the second container and the seventh container into the overhaul state, and the error locking is triggered for explanation when the operation and maintenance are not executed by the staff according to the target task step information after verification. Accordingly, it is necessary to first switch the second container from operation to service and then switch the seventh container from operation to service while performing the task. When the operation of each container is changed into maintenance, the system main switch of the container is firstly closed, and then the door of the container is opened to enable workers to enter.

Taking the first operation step as an example, if the worker performs the operation at the seventh container first, it indicates that the sequence of the operation steps is wrong, and the anti-misoperation lock of the seventh container will be triggered. If the worker firstly operates the second container, the operation steps are in correct sequence, and the step content is further verified. And if the staff does not disconnect the system master switch of the second container and directly requests to open the door of the second container, the step content is considered to be inconsistent with the step content of the step required to be executed at the moment, and the misoperation-preventive locking of the second container is also triggered. If the staff firstly executes the operation of disconnecting the system main switch of the second container, the operation step content is consistent with the step content of the currently required execution step, at the moment, the currently executed step is matched with the currently required execution step, the misoperation prevention locking is not needed, and after the current step is completed, the next step is executed.

Referring to fig. 16 and 17, in order to facilitate understanding of the technical solution of the present application, the present application is explained with reference to more detailed embodiments.

In the technical scheme of the embodiment, a worker directly interacts with a server, and when the battery energy storage system is operated and maintained, a task instruction sent by the worker is firstly received, for example, the second container and the seventh container are changed from an operation state to a maintenance state, and state parameters of the battery energy storage system are obtained, wherein the state parameters comprise operation state parameters and self parameters, and the operation state parameters comprise working states of all parts of the battery energy storage system, such as voltage, current, and opening and closing states of a switch or a relay; the parameters of the system comprise the number of containers, the number of energy storage modules in each container, the positions and the number of switches or relays of each energy storage module and the like.

And then the server verifies whether the received task instruction meets preset verification conditions, specifically, the task corresponding to the task instruction is verified, whether the logic that the container in operation is not allowed to enter, the container not in the power failure range is not allowed to enter, personnel is not allowed to enter when the switch and the relay are closed is met, and the like. If the task corresponding to the task instruction needs to follow at least one corresponding check logic in the preset check conditions, the task instruction is considered to meet the preset check conditions, the preset task step database is traversed by combining the task instruction and the state parameters of the battery energy storage system, and the steps stored in the preset task database and needed to be executed by the task corresponding to the task instruction are combined for screening and combining to obtain task step information of at least one completely executed task.

And then pushing the task step information with the least steps in the task step information to a display interface of the server for displaying so as to be selected and confirmed by the staff. And if the staff chooses to accept, the task step information with the least steps is taken as the target task step information, and the target task step information is pushed and displayed to the staff and all devices in the battery energy storage system which are in direct or indirect communication with the server. And if the staff selects to modify, modifying according to a modification instruction fed back by the staff, taking the modified task step information as target task step information, and pushing and displaying the target task step information to the staff and all devices in the battery energy storage system, which are in direct or indirect communication with the server. And finally, after receiving the acknowledgement instruction fed back by each device, completing the generation and the issuing of the target task step information, and then entering a verification analysis stage of the execution and real-time action information.

In the process of executing each step, the battery energy storage system is caused to act, so that the specific operation executed by the staff on the battery energy storage system, namely what step the staff has executed, can be determined by receiving the real-time action information of the battery energy storage system. Firstly, real-time action information (namely a position signal of the illustrated device) of the battery energy storage system is obtained, and then whether the step sequence of the current execution step of a worker is correct or not is analyzed according to the real-time action information. If the current execution sequence of the steps is correct, namely the steps are sequentially executed according to the step sequence corresponding to the target task step information, whether the step content is consistent with the content of the current required execution step corresponding to the target task step information is further analyzed. If the executed steps are inconsistent or the executed steps are not in the same sequence, the server obtains the check result of the operation and maintenance which is not executed according to the target task step information, at the moment, alarm prompt information is output, and/or the battery energy storage system is controlled to enter an anti-misoperation locking running state, so that potential safety hazards caused by continuous operation are avoided. If the executed steps are consistent in sequence and content, the current executed step is matched with the current required executed step, the operation and maintenance result is checked to obtain according to the target task step information, the misoperation-preventive locking is not needed, the next step can be executed continuously by the staff, the server returns to the operation of obtaining the real-time action information of the battery energy storage system until all steps corresponding to the target task step information are executed, and the operation and maintenance of the battery energy storage system are completed.
