The embodiment of the application provides a method for testing the charge and discharge performance of a flow battery, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the method for testing the charge and discharge performance of the flow battery.
In this embodiment, the method for testing the charge and discharge performance of the flow battery includes the following steps:
step S10: and when the test request is received, determining the object to be tested according to the test request.
In this embodiment, the test request refers to a test request for the target flow battery. The flow battery is a unique electrochemical energy storage technology, and electric energy storage and release are realized through valence state changes of ions in electrolyte. The flow battery test system is composed of an AC/DC rectification inversion assembly, a charge-discharge DC/DC assembly, a monitoring module, a communication control assembly and a man-machine interaction assembly at present, wherein the man-machine interaction assembly in the four assemblies is replaced by an upper computer. The upper computer is developed based on windows system, man-machine interaction is carried out by NBTTestControl-AdV5.0 series software, and main functional equipment is connected, channels are selected, attributes are modified, operation is used and the like. The intermediate board belongs to a communication component, is connected with the upper computer software to communicate, receives, stores and executes an operation instruction issued by the upper computer, controls the main board, receives the data issued by the main board, stores and returns the data to the upper computer for interface display.
It can be understood that the system in this embodiment is mainly an acquisition and monitoring module, which has a large amount of switching signals and complex control logic, and the control logic is as follows: adding a single BMS interface, and BMS data display and control interface (A provides a reference interface) comprising an automatic start/stop operation button of the circulating pump for test; display "device status and operation data of BMS"; the abnormal state of the BMS equipment such as the unreasonable BMS, light fault, heavy fault, scram and communication interruption between the upper computer and the BMS system has specific single-item prompt and record; recording the start-stop operation of the circulating pump; adding a control function: when the test scheme is executed, the BMS is not ready, communication between the PCS and the BMS is interrupted, and any signal does not allow the PCS to charge and discharge; after the charge and discharge are started, BMS is not ready, communication between the PCS and the BMS is interrupted, and any signal is used for interlocking to suspend the charge and discharge; after the charge and discharge are finished, the circulating pump is automatically stopped; the communication of the upper computer and the BMS system defaults to a connection state, and the upper computer and the BMS system can be manually disconnected, so that the communication interruption of the upper computer and the BMS system is realized, and the charging and discharging are not suspended in an interlocking manner. BMS parameters and operational data processing, and detailed data/process data/cyclic data processing functions functionally equivalent to raw data include, but are not limited to, display, recording, storage, import and export functions. And adding SOC calculation, and performing data display, recording, storage, importing and exporting functions.
In a specific implementation, determining the object to be tested according to the test request refers to determining specific basic information of the object to be tested according to specific request content in the test request in this embodiment. If a plurality of flow batteries to be tested exist currently, judging whether the test request contains specific test target requirements or not when the test request is received, and if not, selecting among the current plurality of flow batteries to be tested according to the test weights. The test weight refers to a test priority, which is set by a system manager in the background according to actual use requirements, and if the test priority is not set, the flow battery to be tested is selected randomly.
Step S20: basic information of the object to be tested is obtained, and limiting conditions are determined according to the basic information.
It should be noted that, basic information of the object to be tested is obtained, where the basic information refers to an anode temperature, a cathode temperature, an anode storage tank temperature, a cathode storage tank temperature, an ambient temperature, an anode pressure, a cathode pressure, an anode flow, a cathode flow, a BMS battery voltage, a BMS battery current, an anode pump current rotation speed, a cathode pump current rotation speed, an anode current power, a cathode current power, and the like of the liquid flow battery to be tested.
In a specific implementation, determining the constraint according to the basic information refers to classifying according to the basic information, and generating the corresponding constraint under each class according to the determined classification category, for example: the corresponding maximum test voltage limit condition under the positive electrode port can be generated according to the specific material information of the port.
Further, in order to reasonably generate the constraint condition, the step of acquiring the basic information of the object to be tested and determining the constraint condition according to the basic information includes: basic information of a to-be-tested object is obtained; generating a basic image of the object to be tested according to the basic information; acquiring a preset limiting condition database, and traversing in the preset limiting condition database according to the basic portrait to acquire a traversing result; and determining the limiting condition according to the traversing result.
The basic portrait of the object to be tested refers to a tag set composed of a certain number of tags carrying specific contents. The basic image of the object to be tested is determined, so that the basic information corresponding to the object to be tested can be effectively arranged, and the basic information can be quickly acquired according to the label name when the basic information is required to be called.
It may be understood that performing traversal according to the basic portrait in the preset constraint condition database means that traversal conditions are generated according to tag information in the basic portrait, the generated traversal conditions include specific tag content, and traversal is performed in the preset constraint condition database according to the tag content.
In particular embodiments, traversal refers to a Traversal (Traversal) that refers to accessing each node in a tree (or graph) in turn along a search path. The operations performed by the access node depend on the particular application problem, which may be checking the value of the node, updating the value of the node, etc. The order of access nodes is different in different traversal modes. Traversal is one of the most important operations on a binary tree, which is the basis for performing other operations on the binary tree.
It can be understood that determining the constraint condition through the traversal result refers to classifying specific constraint parameters in the traversal result according to corresponding label types, and forming the classified labels into the constraint condition.
It should be noted that, the step of generating the basic image of the object to be tested according to the basic information includes: determining a basic category and basic content corresponding to the basic category in basic information; generating a label category according to the basic category; filling the basic content as filling content in the tag class; and acquiring the current label category after filling and generating a basic image of the object to be tested according to the label category.
The basic category is specific classification information, and the basic content corresponding to the basic category is specific basic content under the classification information.
In a specific implementation, acquiring the current tag category after filling and generating a basic image according to the tag category refers to combining tags carrying contents and taking a finally generated tag set as the basic image.
Step S30: and determining an environment limiting condition in the limiting conditions, and judging whether the first test requirement is met or not according to the current test environment.
It should be noted that, in the present embodiment, the first test requirement is only used for distinguishing the naming, and there is no other related meaning about the sequence and the importance, so the naming of the first test requirement in the present embodiment is not limited in practice.
It can be appreciated that, before testing the flow battery to be tested, test judgment needs to be performed with respect to the current testing environment, so as to judge whether the current testing environment meets the first testing requirement.
In a specific implementation, the first test requirement refers to whether the corresponding test security requirement, test validity requirement and test base requirement in the current test environment are met.
Further, in order to improve the accuracy of the determination of whether the first test requirement is met, determining an environmental constraint in the constraint and determining whether the first test requirement is met in combination with the current test environment, the method includes: acquiring preset screening information and determining environmental limiting conditions in limiting conditions according to the preset screening information; acquiring environment information corresponding to a current test environment; determining a basic limiting condition and a test limiting condition according to the environment limiting condition; judging whether the environment information meets basic limiting conditions or not; if yes, judging whether the first test requirement is met according to the environmental information and the test limiting condition.
It should be noted that, the preset screening information in this embodiment refers to a screening policy for classifying specific constraint conditions in constraint conditions, and in order to achieve the effect of classifying constraint conditions, the preset screening information may include logic for screening the constraint conditions and definition of screening options.
The step of determining the basic constraint condition and the test constraint condition according to the environmental constraint condition includes: acquiring a constraint condition label in an environment constraint condition; judging whether the classification requirement is met according to the constraint condition label; if yes, determining a basic limiting condition and a test limiting condition in the environment limiting conditions according to the limiting condition label.
The basic constraint condition refers to a condition for limiting a basic environmental parameter; the test limiting condition refers to the limiting condition of the test parameters in the test process. Wherein the test constraints may include: testing related limiting conditions such as pressure, current and the like; the base limit may be an oxygen concentration, an ambient temperature, or the like.
Step S40: if so, determining a test strategy according to the test request, testing the object to be tested according to the test strategy, and recording test data.
In the test of the charge and discharge performance of the flow battery in this embodiment, it is necessary to ensure that the test environment is stable, the charge and discharge ends are consistent, the electrolyte state is consistent,
1) Test environment: mainly testing the environment temperature, the electrolyte temperature and the galvanic pile temperature. If the battery performance is insensitive to temperature, the normal temperature environment test can be directly carried out; in addition, if the electrolyte needs inert gas protection, the inert gas protection state is required to be ensured in the test process, and if the inert gas environment cannot be ensured, the same test environment is required to be given.
2) Charge-discharge cutoff conditions: if the SOC is used as a charge and discharge cut-off condition, the accuracy and stability of SOC monitoring are required to be ensured, and the voltage is generally recommended to be used as the charge and discharge cut-off condition, so that the occurrence of positive and negative side reactions can be ensured, meanwhile, the cut-off condition is stable, the examination is better stabilized, the influence of the side reactions is conveniently eliminated, and meanwhile, the influence factors of the SOC can be reduced as much as possible; for monitoring the SOC of the flow battery, the current flow battery engineering mainly uses a bypass monomer or ORP to monitor the potential, and the actual principle of the two methods is the same, and the potential of the electrolyte is monitored to judge the SOC. The measurement is illustrated by taking an all-vanadium redox flow battery as an example: the anode and cathode solutions of the all-vanadium redox flow battery are vanadium ions with different valence states, and the supporting electrolyte is sulfuric acid. The anode and cathode solutions are vanadium ions, so that the problem of cross contamination is avoided.
Step S50: and acquiring a preset condition list, and judging whether the current test strategy meets the cut-off condition according to the basic information.
It should be noted that, in this embodiment, the preset condition list is used to limit the test cut-off node, and when the cut-off condition corresponding to the preset condition list is satisfied, the test should be stopped and the test record should be obtained. Therefore, the function of setting up the preset condition list is mainly for the definition of the test cutoff condition.
Further, in order to promote the rationality of judging whether the cut-off condition is satisfied, a preset condition list is obtained, and whether the current test strategy satisfies the cut-off condition is judged according to the basic information, including: acquiring a preset condition list; determining a list traversing condition according to the basic information; traversing in a preset condition list according to the list traversing conditions and acquiring traversing results; judging whether the current test strategy meets the cut-off condition according to the traversing result.
In this embodiment, a list traversing condition is determined according to the basic information, where the list traversing condition refers to a basic condition for traversing in a preset condition list. Determining a list traversal condition based on the base information refers to a search condition generated based on the base information category and the base information in the base information. According to the basic information category as the searched title, traversing is firstly carried out in a preset condition list according to the title, after the target condition information corresponding to the title is determined, and comparison is carried out according to the content corresponding to the title and the limiting condition corresponding to the preset condition list so as to judge whether the content is met or not.
The step of determining the list traversal condition according to the basic information includes: determining basic state information, basic material information and basic demand information in the basic information; determining a state condition according to the basic state information; determining material conditions according to the basic material information; determining a demand condition according to the basic demand information; and generating list traversing conditions according to the state conditions, the material conditions and the requirement conditions.
Step S60: if yes, stopping testing the object to be tested and acquiring current test data.
In the specific implementation, if the current testing strategy is judged to not meet the cut-off condition according to the basic information, the flow battery to be tested is continuously tested according to the testing request, and the testing is stopped until the current testing strategy is judged to meet the cut-off condition according to the basic information.
Step S70: and taking the current test data as a test result of the object to be tested.
In the embodiment, when a test request is received, a to-be-tested object is determined according to the test request; basic information of a to-be-tested object is obtained, and limiting conditions are determined according to the basic information; determining an environment limiting condition in the limiting conditions and judging whether the first test requirement is met or not by combining the current test environment; if yes, determining a test strategy according to the test request, testing the object to be tested according to the test strategy, and recording test data; acquiring a preset condition list, and judging whether the current test strategy meets a cut-off condition according to basic information; if yes, stopping testing the object to be tested and acquiring current test data; and taking the current test data as a test result of the object to be tested. By judging two judging modes of the test environment and the cut-off condition, the judgment of the test environment and the cut-off element of charge and discharge is realized, and the technical effect of reasonably and effectively testing the flow battery is realized.
In addition, the embodiment of the application also provides a computer readable storage medium, wherein the storage medium stores a program for testing the charge and discharge performance of the flow battery, and the program for testing the charge and discharge performance of the flow battery realizes the steps of the method for testing the charge and discharge performance of the flow battery when being executed by a processor.
Referring to fig. 3, fig. 3 is a block diagram illustrating a first embodiment of a flow battery charge/discharge performance test system according to the present application.
