Description

Technical Field

[0001] The present application relates to the technical field of batteries, and particularly to an automated testing method for an energy storage system, an electronic device, and a storage medium. Background Art

[0002] With the rapid development of new energy technologies, as a key component of them, the stability and reliability of the performance of an energy storage system are crucial for the safe operation of the entire energy system. An energy storage system usually consists of multiple modules, and the insulation performance and voltage withstand ability of these modules are directly related to the safety and service life of the system. Therefore, accurately and efficiently testing the insulation and voltage withstand performance of an energy storage system is an important link to ensure its reliability.

[0003] Traditional testing methods for energy storage systems mainly rely on manual testing. By manually operating an insulation resistance and voltage tester, the insulation or voltage withstand function of a single module is tested. However, traditional testing methods for energy storage systems have some defects. For example, only a single module can be tested at a time, which limits the overall testing efficiency. Especially when a large number of modules need to be tested, the repeated wiring and testing processes are not only time-consuming and laborious, but also lack flexibility and are difficult to meet the requirements of large-scale production. In addition, after each test is completed, it is necessary to manually record the test results and determine whether the test results are qualified, which not only increases the labor cost, but also increases the risk of data recording errors or inaccurate result determination caused by human factors. That is, the existing testing technologies have problems of low testing efficiency, large workload, and difficulty in ensuring accuracy due to manual testing.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0041] An embodiment of the present application provides a method, device, electronic device, and storage medium for automatically testing an energy storage system.

[0042] Among them, the automatic test device for the energy storage system can be specifically integrated in a terminal. The terminal can include a tablet computer or a personal computer (PC, Personal Computer). The terminal can establish a wired or wireless connection with a server. The server can include an independently operating server or a distributed server, or can also include a server cluster composed of multiple servers.

[0043] The following will be described in detail respectively. It should be noted that the description order of the following embodiments does not limit the priority order of the embodiments.

[0044] An automated testing method for an energy storage system, comprising: connecting a test harness to a test point of the energy storage system; automatically controlling a test circuit through a control unit to perform an automated test on the energy storage system and generate a test result; automatically recording the test result and generating a test report.

[0045] Please refer to Figure 1 , Figure 1 , which is a schematic flowchart of the automated testing method for the energy storage system provided by the embodiment of the present application. The specific process of this automated testing method for the energy storage system can be as follows:

[0046] 101. Connect the test harness to the test point of the energy storage system.

[0047] Specifically, for step 101, connect the test harness to the test point of the energy storage system to ensure that each test point can accurately receive test signals. This step is the basis of the test process, and it is required that the connection between the test harness and the energy storage system must be stable and reliable to ensure the accurate transmission of test signals. For example, the test harness includes multiple test channels and can be connected to multiple energy storage system modules for testing simultaneously. For example, connect the plug or clip of the test harness to the test point of the energy storage system, and multiple test points can be connected according to requirements, with a maximum of 8 modules that can be tested simultaneously.

[0048] It should be noted that the test points in this embodiment refer to the specific electrical connection points on the energy storage module for detecting its insulation performance and withstand voltage ability. These test points are the key positions for electrical signal interaction between the test system and the energy storage module, and are used to apply test voltages, measure currents, or detect insulation resistances, etc. In a specific embodiment, the test points in this embodiment can be one or more of insulation test points, withstand voltage test points, internal circuit test points, inter-module connection points, and system-level test points.

[0049] Among them, the insulation test point is used to detect the insulation performance between the energy storage module and the ground, and is usually connected to the shell or grounding end of the module to ensure that there is no leakage or short circuit phenomenon during the operation of the module. For example, the insulation test point can be a grounding copper bar connection point. In an energy storage system, there is usually a grounding copper bar for centralized grounding. The test point can be a grounding wire harness clip connected to the grounding copper bar for detecting the insulation resistance between the module and the ground. Another example is that the insulation test point can also be a module shell test point. The shell of the energy storage module usually requires good insulation performance, and the test point can be a specific connection point on the shell for detecting the insulation between the shell and the internal circuit.

[0050] The withstand voltage test point is used to detect the insulation strength of the energy storage module under high voltage. It is usually connected to the input / output terminals of the module or the key nodes of the internal circuit to ensure that the module will not break down under high voltage. For example, the withstand voltage test point can be the input terminal of the module. The input terminal of the energy storage module is an important position for the withstand voltage test. The test point can be the connection point of the input terminal, which is used to apply high voltage and detect the withstand voltage ability of the module. Another example is that the withstand voltage test point can also be the output terminal of the module. Similar to the input terminal, the output terminal also needs to be subjected to the withstand voltage test. The test point can be the connection point of the output terminal, which is used to detect the insulation performance of the module under high voltage.

[0051] The internal circuit test point is used to detect the insulation and withstand voltage performance of the internal circuit of the energy storage module. It is usually located at the key nodes inside the module, such as the connection points of capacitors, inductors or semiconductor devices. For example, the internal circuit test point can be both ends of the capacitor. The capacitor in the energy storage module is a key component, and its insulation performance directly affects the safety of the module. Both ends of the capacitor are used to detect the insulation and withstand voltage ability of the capacitor. Another example is that the internal circuit test point can also be the connection point of the pins of the semiconductor device. The pins of semiconductor devices (such as MOSFETs, IGBTs) require good insulation performance, which is used to detect the insulation and withstand voltage conditions of the device.

[0052] In an energy storage system, multiple energy storage modules are usually connected in series or in parallel through connecting wires. These connection points need to be subjected to insulation and withstand voltage tests to ensure the safety of the entire system. The connecting wires between the energy storage modules are the key parts of the system. The test point can be both ends of the connecting wire, which is used to detect the insulation and withstand voltage performance of the connecting wire. In some cases, the middle node of the connecting wire also needs to be tested. The test point can be the connection point of the middle node, which is used to detect the insulation condition of the entire connecting wire.

[0053] In addition to the test points of individual modules, the energy storage system may also need to conduct system-level insulation and withstand voltage tests. The test points are usually located at the overall connection points of the system. For example, the overall grounding end of the energy storage system is an important test point, which is used to detect the grounding insulation performance of the entire system. In addition, the input and output ports of the energy storage system need to be subjected to withstand voltage tests to ensure the safety of the system under high voltage. The test point can be the connection point of these ports, which is used to detect the overall withstand voltage ability of the system.

[0054] Optionally, in some embodiments, step 101 "Connect the test harness to the test point of the energy storage system" may specifically include:

[0055] Obtain the test requirement information corresponding to the test task;

[0056] Specifically, first, the system needs to obtain test requirement information corresponding to the test task, including key information such as specific parameters of the test, modules to be tested, and test sequence. The test requirement information will guide the subsequent automated test process.

[0057] Based on the test requirement information, connect the grounding wire harness in parallel to the grounding copper bar position of the container body, and connect the test wire harness in parallel to multiple test points corresponding to the energy storage system.

[0058] Specifically, based on the test requirement information, connecting the grounding wire harness in parallel to the grounding copper bar position of the container body ensures electrical safety during the test and prevents possible electric shock or equipment damage. Also based on the test requirement information, connecting the test wire harness in parallel to multiple test points corresponding to the energy storage system enables simultaneous testing of multiple energy storage modules, greatly improving the test efficiency.

[0059] Among them, before wiring, it is necessary to standardize the design of the grounding wire harness and the insulation test wire harness; design an adjustable test point connection device to connect the test points of energy storage systems of different models through the test point connection device.

[0060] In addition, by integrating an intelligent identification system, automatically identify the test points and the grounding copper bar position to ensure the accuracy of the connection and avoid human wiring errors. And real-time monitor the wiring status, real-time monitor the stability and integrity of the connection. Once a connection problem (such as missed connection, wrong connection or incomplete connection) is found, immediately issue an alarm to prompt the user to take relevant measures for handling. During the connection process, if an abnormality is found, the intelligent diagnosis system will diagnose the cause of the wiring fault and provide a solution.

[0061] 102. Automatically control the test circuit through the control unit to perform an automated test on the energy storage system and generate test results.

[0062] Specifically, for step 102, automatically control the test circuit through the control unit to perform an automated test on the energy storage system and generate test results. The control unit automatically switches the test circuit according to the preset test parameters to perform insulation and withstand voltage tests on each module in the energy storage system, and obtains the test results corresponding to each module. For example, through the control unit (such as a test cabinet) and a high-voltage one-to-twelve relay board, automatically control the insulation / withstand voltage test circuit according to the preset parameters to achieve an automated test.

[0063] In addition, the intelligent scheduling system can automatically arrange the test sequence and resource allocation according to the test requirements and resource status, optimize the test process, reduce the waiting time, and improve the test efficiency. Or develop an adaptive algorithm to dynamically adjust the test parameters according to the historical test data and the current test results to adapt to the characteristics of different modules and the changes in the test environment.

[0064] The control unit automatically executes the test process according to the preset test parameters, reducing manual intervention and improving the consistency and accuracy of the test. Additionally, intelligent algorithms can be introduced to optimize the test sequence and parameters, and the test plan can be dynamically adjusted based on the historical test data and status of the energy storage module to achieve a more efficient test process. The control unit can adaptively adjust the test parameters according to the real-time feedback test data to cope with the differences between different modules, improving the flexibility and adaptability of the test.

[0065] Optionally, in some embodiments, step 102, "automatically control the test circuit through the control unit to perform an automated test on the energy storage system and generate test results", may specifically include:

[0066] Set the test parameters corresponding to the test cabinet based on the test requirement information;

[0067] Specifically, set the test parameters corresponding to the test cabinet based on the test requirement information. The test parameters may specifically include, but are not limited to, test voltage, current, frequency, duration, etc., to ensure that the test is carried out according to the predetermined standards and conditions. Users can also remotely set the test parameters through the Internet, improving the convenience of operation, especially in a multi-location distributed test environment.

[0068] Automatically control the corresponding test circuit through the control unit based on the test parameters to perform an automated test on multiple energy storage modules to be tested in the energy storage system and generate test results;

[0069] Specifically, the control unit automatically switches and controls the high-voltage relay board according to the set parameters to selectively test multiple energy storage modules to be tested in the energy storage system. Perform an automated test on multiple energy storage modules to be tested in the energy storage system and generate test results. During the test process, the control unit monitors the test status and judges whether the test is successful according to the feedback signal. At the same time, a safety interlock mechanism is designed to ensure that if an abnormal situation is detected during the test, the test will automatically stop to protect the safety of the equipment and operators. Additionally, a user interface can be provided to display the test progress and status in real time, enabling users to intuitively monitor the test process.

[0070] Optionally, in some embodiments, the step "automatically control the corresponding test circuit through the control unit based on the test parameters to perform an automated test on multiple energy storage modules to be tested in the energy storage system and generate test results" may specifically include:

[0071] Determine the test sequence of multiple energy storage modules to be tested in the energy storage system based on the test requirement information and test parameters;

[0072] Specifically, based on the test requirement information and test parameters, determine the test sequence of multiple energy storage modules to be tested in the energy storage system, such as based on the priority, test difficulty, or other operation logics of each energy storage module to be tested. Additionally, the test sequence can be automatically optimized to reduce the total test time, or prioritize the testing of key energy storage modules for the identified weaknesses.

[0073] Among them, the test requirement information and test parameters in this embodiment respectively refer to the guiding information and operation parameters set according to specific test tasks and objectives, serving as the basis for ensuring the smooth progress of the test and achieving the expected purpose.

[0074] In a specific embodiment, the test requirement information refers to the specific requirements that need to be met during the test. The test requirements are usually determined by the nature of the test task, the characteristics of the test object, and the expected test objectives. The test requirement information usually includes the specifications of the test object, test objectives, test environment requirements, test sequence, and requirement information corresponding to the priority. For example, the requirement information for the test objective is to detect the insulation performance or withstand voltage ability, or both. If the test objective is to detect the insulation performance of the module, the requirement information will clearly state that an insulation resistance test needs to be conducted; if the test objective is to detect the withstand voltage ability, it will clearly state that a withstand voltage test needs to be conducted. Another example is that the requirement information for the test sequence and priority mainly determines the sequence of multiple modules and which modules need to be tested first. If there are multiple modules in an energy storage system, the requirement information may specify to test Module 1 and Module 2 first, and then test Module 3 and Module 4.

[0075] In a specific embodiment, the test parameters refer to the specific operation parameters that need to be set during the test. The test parameters directly affect the execution process and results of the test. The test parameters can be the test parameters corresponding to the test voltage, test time, current threshold, resistance threshold, test frequency, and relay control parameters respectively. For example, the test parameter for the test time refers to the duration of the test, and the test time corresponding to different test tasks is also different. The insulation test may need to last for 1 minute, and the withstand voltage test may need to last for 5 minutes. Another example is that the test parameter for the test frequency refers to the voltage frequency applied in the AC withstand voltage test. If the test requirement is to apply an AC voltage of 50HZ, the test parameter will set the frequency to 50HZ.

[0076] The control unit automatically controls the closing of the target relay on the high-voltage relay board according to the test sequence to close the test circuit corresponding to the target relay;

[0077] Specifically, the control unit closes the corresponding relay on the high-voltage all-twelve relay board according to the test sequence to close the test loop corresponding to the target relay and then conducts the test. Additionally, a relay status monitoring system can be integrated to monitor the working status of the relay in real time to ensure the correct closing and opening of the relay.

[0078] The control unit conducts an insulation test or a withstand voltage test on the test loop based on the test parameters and generates corresponding test results;

[0079] Specifically, the test cabinet conducts an insulation performance test and / or a withstand voltage performance test on the closed test loop according to the test parameters, and generates test results of the energy storage modules corresponding to each test loop after the test. During the test, the test parameters are dynamically adjusted according to the real-time feedback to adapt to the characteristics of different modules or environmental changes, or the health of the test loop is monitored to detect potential faults or damages in a timely manner.

[0080] Optionally, in some embodiments, after the step "The control unit conducts an insulation test or a withstand voltage test on the test loop based on the test parameters and generates corresponding test results", it may further specifically include:

[0081] The control unit automatically controls the target relay to open;

[0082] The control unit automatically controls the next target relay on the high-voltage relay board to close according to the test sequence, and continues to conduct an insulation test or a withstand voltage test on the test loop corresponding to the next target relay, repeating the test process until all target relays are tested.

[0083] Specifically, after the test is completed, the control unit automatically controls the target relay to open to ensure the safe disconnection of the test loop. According to the test sequence, the control unit automatically controls the next target relay on the high-voltage relay board to close, and continues to conduct an insulation test or a withstand voltage test on the test loop corresponding to the next target relay. Repeat the above test process until the test loops corresponding to all target relays are tested. During the test, the test sequence can be dynamically adjusted according to the obtained test results and test progress to optimize the test process. A fault self-recovery mechanism can also be provided so that when a fault occurs during the test, the system can automatically attempt to resume the test process.

[0084] Optionally, in some embodiments, the step "The control unit conducts an insulation test or a withstand voltage test on the test loop based on the test parameters and generates corresponding test results" may further specifically include:

[0085] During the insulation test or the withstand voltage test, the circuit state of the test loop is monitored in real time, and the insulation test data or the withstand voltage test data corresponding to the test loop is automatically collected;

[0086] Generate the test results of the energy storage module to be tested corresponding to the test circuit based on the circuit state, insulation test data, and withstand voltage test data.

[0087] Specifically, during the test, the circuit state of the test loop is monitored in real time, including parameters such as voltage, current, and resistance, to ensure the accuracy and safety of the test. Automatically collect the insulation test data or withstand voltage test data corresponding to the test loop, which are crucial for evaluating the performance of the energy storage module. Finally, based on the collected circuit state, insulation test data, and withstand voltage test data, generate the test results of the energy storage module to be tested corresponding to the test circuit. During the test, the test strategy can be dynamically adjusted according to the test data, such as changing the test parameters or test sequence, to optimize the test process and improve the test efficiency.

[0088] In addition, data analysis can also be performed through machine learning algorithms to identify patterns and anomalies in the test data and improve the accuracy of fault detection. And predict the maintenance requirements of the energy storage module based on historical and real-time test data to reduce unexpected downtime.

[0089] 103. Automatically record the test results and generate a test report.

[0090] Specifically, for step 103, the test results are automatically recorded by the test cabinet and a test report is generated. For example, the test data is captured in real time through a data acquisition system, and a test report is automatically generated based on the test data. The report includes the test results and performance judgments of each module, facilitating data traceability and statistical analysis. The test results or test report can also be visually displayed through visualization tools in the form of charts, graphs, etc., for easy understanding and analysis by users.

[0091] In addition, provide a customized report function for users, allowing users to select the report content and format according to their needs, improving the usability and pertinence of the test report; develop in-depth analysis tools to perform statistical and trend analysis on the test results to help users identify performance bottlenecks and improvement points.

[0092] Optionally, in some embodiments, step 103 "Automatically record the test results and generate a test report" may specifically include:

[0093] Automatically record the test results corresponding to each energy storage module to be tested in the energy storage system;

[0094] Specifically, automatically record the test results corresponding to each energy storage module to be tested in the energy storage system, including key parameters such as insulation resistance and withstand voltage level. Store the obtained test data in a highly reliable database to ensure the integrity and traceability of the data. Perform tagging processing on the test data for easy subsequent query and analysis, such as classifying by module, date, test type, etc.

[0095] Judge the preset result according to the preset standard rules to obtain the performance judgment result corresponding to the energy storage module to be tested;

[0096] Specifically, judge the test result according to the preset standard rules to obtain the performance judgment results corresponding to each energy storage module to be tested, including the insulation performance judgment result and the withstand voltage level judgment result, and judge whether the energy storage module to be tested meets the quality standard. For example, according to industry standards and enterprise specifications, preset performance judgment rules, and analyze the test data according to the preset rules through an automatic judgment system to judge whether the energy storage module is qualified. For the test results judged as abnormal or unqualified, an abnormal handling process is automatically triggered for further analysis and processing.

[0097] Collect the test results and performance judgment results corresponding to each energy storage module to be tested to generate a test report corresponding to the energy storage system;

[0098] Specifically, collect the test results and performance judgment results corresponding to each energy storage module to be tested to generate a comprehensive test report corresponding to the energy storage system, providing a basis for subsequent decision-making. Based on the test results and performance judgment, the test report is automatically generated, reducing the workload of manual report writing. Allow users to customize the report content according to needs, including key performance indicators, test summaries, suggestions, and improvement measures, etc. The test report can also support multiple report formats, such as PDF, Excel, Word, etc., to meet the needs of different users.

[0099] Optionally, in some embodiments, after the step of "judging the preset result according to the preset standard rules to obtain the performance judgment result corresponding to the energy storage module to be tested", it may specifically further include:

[0100] After determining that there is a fault in the test loop corresponding to the energy storage module to be tested based on the performance judgment result, automatically record the fault information corresponding to the test loop;

[0101] Specifically, during the test process, monitor and identify any abnormal situations in real time, such as sudden voltage drops, abnormal currents, etc., and automatically record the time and location of the fault. Detailed record all information related to the fault, including the fault type, the affected module, the test parameters at the time of the fault, etc., for subsequent analysis. In addition, a fault log system can be established to store and manage all fault events to ensure the integrity and traceability of the information.

[0102] Generate an abnormal alarm message based on the fault information;

[0103] Specifically, through the abnormal alarm system, alarm information is automatically generated when a fault is detected. The alarm information includes the severity of the fault, the affected scope, recommended emergency measures, etc., ensuring that relevant personnel can respond promptly. It supports sending alarm information through multiple channels such as emails, text messages, and application push, ensuring that the information can be conveyed to relevant personnel in a timely manner. And intelligent filtering of alarm information is carried out to reduce false alarms and repeated alarms, improving the accuracy of alarms.

[0104] Push the abnormal alarm information to the intelligent terminal for alarm.

[0105] Specifically, integrate the alarm system into intelligent terminals such as test cabinets, mobile phones, and tablets, ensuring that relevant personnel can receive alarm information anytime and anywhere. Design an intuitive and easy-to-use user interface, enabling operators to quickly view the alarm information and take corresponding measures, providing operation guides and fault handling processes to help operators take correct actions promptly after receiving the alarm.

[0106] To facilitate the understanding of the energy storage system automation test method provided in this embodiment, this embodiment also provides a specific implementation method, and the specific process is as follows:

[0107] Connect the test harness mating plug (or clip) to the test point (connect as required). The test cabinet controls the insulation / dielectric withstand test circuit through the high-voltage all-in-one twelve-relay board to implement the function of testing whether the insulation or dielectric withstand of multiple modules is qualified at one time. Clip the ground wire harness clip to the grounding copper bar position of the container body, and connect the insulation test harness mating plug (or clip) to the test point (connect as required, up to 8 channels can be tested simultaneously); according to the set parameters, the test cabinet closes the corresponding relay of the high-voltage all-in-one twelve-relay board to test a single loop; after the single loop test is completed, close the control loop relay, and the test cabinet generates corresponding test results (insulation OK / insulation NG / dielectric withstand OK / dielectric withstand NG) through the feedback signal of the control loop relay; repeat the above steps to continue the test until the 8-channel test is completed.
