[0043] In the current traditional method, personnel are required to manage the laboratory during the lithium battery testing process, resulting in low management efficiency and high costs.

[0044] To this end, the present application proposes a lithium battery test management method, device and medium.

[0045] See attached Figure 1 , Figure 1 It is a main process diagram of a lithium battery test management method according to an embodiment of the present application.

[0046] like Figure 1 As shown, the lithium battery test management method in the embodiment of the present application mainly includes the following steps S10 to S40.

[0047] Step S10: Responding to the user's operation instruction, obtaining the target test items of the lithium battery.

[0048] The user's operation instruction refers to a command or request issued by the user in some way, the purpose of which is to make the system or device perform a specific operation, that is, to obtain the target test items of the lithium battery. For example, the user triggers the operation instruction by clicking a button, selecting a menu item, or filling out a form through the computer's application program interface.

[0049] Target test items refer to specific items or parameters that need to be focused on and measured during the lithium battery testing process. They are usually selected based on the purpose and requirements of the test, such as the battery capacity, model, power, voltage and other information.

[0050] Specifically, the target test item can be obtained by user input through a computer interface.

[0051] Step S20: Acquire the test type and test level based on the target test item.

[0052] Test types refer to different types of tests divided according to the purpose and method of the test. For example, they may include but are not limited to storage tests, cycle tests, and safety tests.

[0053] Test level refers to the priority of test tasks. For example, "urgent testing" (needs to be completed quickly) and "regular testing" (performed according to the normal test plan). Setting test levels helps optimize resource allocation and ensure that important test tasks can be completed in a timely manner.

[0054] Specifically, the target test item includes relevant information about the test type and the test level, and the test type and the test level can be obtained according to the target test item.

[0055] Step S30: Acquire test data based on the test type and test level.

[0056] The test data refers to various information and results about the performance of lithium batteries collected during the entire test process. These data may include but are not limited to voltage value, current value, temperature change, capacity decay rate, test start time, test end time, etc.

[0057] Step S40: Evaluate the overall performance of the lithium battery based on the test data.

[0058] Overall performance refers to the overall evaluation of lithium battery performance obtained through comprehensive analysis of multiple test data.

[0059] Based on the above steps S10-S40, first respond to the user's operating instructions to obtain the target test items of the lithium battery; obtain the test type and test level based on the target test items; obtain test data based on the test type and test level; and evaluate the overall performance of the lithium battery based on the test data. By setting the "test level", laboratory resources can be reasonably allocated according to the urgency of the test task, and urgent or important test tasks can be given priority to ensure the timely completion of key tasks. Acquiring test data based on the test type and test level ensures the standardization and consistency of data collection and improves the quality and accuracy of test data. Finally, the overall performance of the lithium battery is evaluated through the test data, and the various performance indicators of the lithium battery can be comprehensively analyzed to obtain comprehensive and objective performance evaluation results. By standardizing the test process, it is helpful to establish unified test standards and processes, which is conducive to improving the management efficiency of lithium battery testing.

[0060] The above steps S30 to S40 are further explained below.

[0061] In a specific embodiment of the present application, the lithium battery performance test includes storage test, cycle test and safety test of the lithium battery, wherein the safety test includes overcurrent test, overcharge test, over-discharge test, thermal runaway test, extrusion test and short circuit test.

[0062] Overcurrent testing is to test the behavior of the battery when excessive current passes through it to evaluate the effectiveness of its overcurrent protection mechanism.

[0063] Overcharge test simulates the reaction of the battery under overcharge condition to ensure that the battery will not cause fire or explosion due to overcharge.

[0064] Over-discharge test is to test the performance of the battery under over-discharge condition to ensure that the battery will not be damaged under over-discharge condition.

[0065] Thermal runaway testing simulates the behavior of batteries at extreme temperatures, especially thermal runaway phenomena, to evaluate the safety of batteries.

[0066] The squeeze test simulates the performance of a battery when it is physically squeezed to ensure that the battery does not rupture or leak when subjected to external mechanical forces.

[0067] The short circuit test is to test the behavior of the battery when the positive and negative poles are in direct contact, resulting in a short circuit, to ensure that the battery will not be dangerous due to the short circuit.

[0068] In a specific implementation of the present application, after determining the test type and the test level based on the target test item and before acquiring test data based on the test type and the test level, the method further includes: acquiring a test device based on the target test item.

[0069] Since different test items have different requirements for test equipment, corresponding test equipment can be assigned to the test items according to the test type. For example, for test items such as "overcharge" and "overdischarge", the overcharge and discharge equipment can be accurately matched; for the "low pressure" test item, a simulated high-altitude low-pressure test chamber will be selected; similarly, the "heating" test item will be arranged in a thermal abuse test chamber, the "extrusion" test item will be carried out using an extrusion test machine, the "short circuit" test item will be implemented in a high-current battery short circuit test machine, and the "puncture" test item will be completed in a puncture machine. This intelligent equipment allocation method not only improves test efficiency, but also ensures the accuracy and reliability of test results.

[0070] In a specific implementation of the present application, after acquiring the test equipment based on the target test item and before acquiring the test data, the method further includes: acquiring a test standard corresponding to the target test item.

[0071] Testing standards include national standards and international standards. Specifically, since each test item needs to follow specific standard specifications, such as IEC-62619, GB / T-36276, UL1973, UN38.3 and GB / T-31485, etc., obtaining the test standards corresponding to the test items according to the specific test items not only improves the standardization and consistency of the test, but also helps to improve the reliability and accuracy of the test, ensuring that the test results meet industry requirements or international standards.

[0072] Specifically, step S30 can be implemented through the following steps S301 to S302.

[0073] Step S301: Use the testing equipment to perform a lithium battery performance test.

[0074] Begin your lithium battery performance testing with selected test equipment, test type, and test level.

[0075] In a specific embodiment of the present application, the test level includes an accelerated test and a regular test; the lithium battery safety test based on the test type includes: when the test level is an accelerated test, an accelerated test is performed based on the target test item; when the test level is a regular test, a regular test is performed based on the target test item.

[0076] In order to meet different requirements in the actual testing process and ensure that expedited testing can be given priority, lithium batteries can be expedited tested according to the user's expedited testing requirements. In this way, expedited testing and regular testing can be accurately distinguished, and expedited testing or regular testing can be performed on test items according to the degree of urgency, thereby achieving efficient allocation and utilization of test resources, which not only improves the flexibility and response speed of the test, but also ensures the efficiency and smoothness of the test process.

[0077] Step S302: Acquire test data during the entire test process.

[0078] In a specific embodiment of the present application, the obtaining of test data includes: obtaining test data in the entire test process based on the test type and test level, wherein the test data is obtained by performing a lithium battery performance test using the test equipment.

[0079] In a specific embodiment of the present application, the test level includes expedited testing and regular testing; the obtaining of test data includes: when the test level is expedited testing, obtaining test data during the expedited testing process; when the test level is regular testing, obtaining test data during the regular testing process.

[0080] Specifically, during the test process, all kinds of information during the lithium battery test (such as routine testing or expedited testing) are recorded in real time, which not only covers the real-time status monitoring of the experimental equipment during the test, but also includes the immediate observation of various safety hazards that may occur during the test, such as abnormal phenomena such as battery cell expansion, leakage, smoking, fire or explosion. In addition, users can supplement the description of other non-standard phenomena that may occur according to actual needs, and also need to record information such as the valve break time of the battery cell test in order to more comprehensively reflect the overall picture of the test process. In order to ensure the accuracy and reliability of safety testing, it is necessary to monitor the test status in real time and continuously update relevant information such as experimental phenomena. These data should be recorded in real time and accurately for subsequent analysis.

[0081] Once the user confirms to start the test, the system will immediately start the timing function and record the start time of the test in real time. At the same time, based on the data obtained by the tester from multiple offline experiments, the user can set the estimated completion time of the test. If the test process goes smoothly, the user will be reminded that the test is completed at the estimated completion time node, and the user can safely disassemble the battery cell. This feature not only improves the automation and intelligence level of the test process, but also provides users with a more convenient and efficient operation experience.

[0082] The acquired test data can be stored in a preset memory, thus ensuring the security and integrity of the data.

[0083] In a specific implementation of the present application, the method further includes: taking photos and uploading the test data obtained during the entire test process.

[0084] Specifically, before the test begins, you can upload a picture of the lithium battery to record in detail the initial state of the battery before the test, which not only helps to retain the original data, but also provides an intuitive and accurate basis for subsequent comparative analysis, thereby ensuring the integrity of the test process and the reliability of the test results. During the test or after the test, you can take photos and upload pictures of the lithium battery during and after the test, so as to accurately capture and save the final state of the battery during and after the test, which helps the tester to make a detailed comparison with the battery state before and during the test, so as to comprehensively and accurately record all aspects of the entire test process.

[0085] The above is a further description of step S30 , and the following is a further description of step S40 .

[0086] Specifically, the test data may include the test start time, the test end time and the lithium battery status information. The above step S40 may be implemented through the following steps S401 to S403.

[0087] Step S401: Determine the test duration based on the test start time and the test end time.

[0088] Step S402: Determine the difference between the test duration and the standard duration.

[0089] The standard duration may be a time value obtained in advance based on experiments or experience, and may be adaptively adjusted according to different usage scenarios, and there is no specific limitation on this.

[0090] Step S403: Evaluate the overall performance of the lithium battery based on the difference and the lithium battery status information.

[0091] The lithium battery status information may include the voltage, current, temperature, internal resistance, charge and discharge status, etc. of the lithium battery.

[0092] Specifically, by comparing the actual test duration with the standard duration and conducting an in-depth analysis, if there is a deviation between the actual test duration and the standard duration, it indicates that there may be some problems in the lithium battery test process, and the problems in the test process can be found out based on the lithium battery status information during the test process. Alternatively, the tester can also conduct an in-depth analysis of the reasons for the difference to ensure the accuracy and reliability of the test and provide valuable reference for subsequent improvements.

[0093] Combining the difference in test time and the status information of the lithium battery, a comprehensive performance evaluation can be performed, which not only considers the impact of time factors on the test results, but also combines the actual performance data of the battery during the test process, thereby providing a more comprehensive and objective evaluation result, which can more effectively identify batteries that do not meet the standards, help ensure that the final product meets the expected quality standards, and reduce the risk of defective products entering the market. The evaluation method based on test time and status information not only improves the accuracy and efficiency of the test, but also enhances the comprehensiveness and reliability of lithium battery performance evaluation, which is conducive to improving the management efficiency of lithium battery testing.

[0094] In a specific embodiment of the present application, the method further includes: generating a lithium battery performance test report based on the test data and the evaluation results; and sending the lithium battery performance test report to a terminal device.

[0095] The terminal device refers to the device that receives the test report, which can be any electronic device with data receiving function, such as a computer, tablet computer, smart phone or other dedicated industrial equipment, etc., without specific limitation.

[0096] Specifically, the test report can be in a format suitable for receiving and displaying by the terminal device, such as PDF, Word document or HTML web page, and sent to the terminal device by email, network file transfer protocol (FTP), cloud storage service or other communication means. After the sending is completed, it can also be confirmed that the report has been successfully received and the recipient can correctly open and read the report.

[0097] In this way, the test data and evaluation results are systematically recorded to facilitate subsequent analysis and archiving, which not only improves the management efficiency and accuracy of lithium battery testing, but also enhances the transparency and availability of test results, thereby better supporting the research and development and quality management of lithium batteries.

[0098] Figure 2 FIG. 1 is a complete schematic diagram of a lithium battery safety test management method in one embodiment of the present application. Figure 2 As shown, the lithium battery safety test management method can be specifically implemented through the following steps S1-S7.

[0099] S1. Automatically assign to the corresponding safety laboratory (test equipment) according to the test type. At the same time, differentiate according to the urgency of the test. For test tasks that require a quick response, the test task will be assigned to the expedited test module first to ensure that it can be processed in a timely manner; for routine test tasks, they will be arranged in the routine test module to ensure the comprehensiveness and accuracy of the test.

[0100] S2. In a unified management environment, relevant pictures / documents before the start of the safety test will be uploaded, and a test method that complies with national or international standards will be selected.

[0101] S3. Start executing the safety test. The system will simultaneously record the exact time when the test is started and the estimated completion time of the evaluation test.

[0102] S4. During the execution of the safety test, the pictures / file information, experimental phenomena, test results and valve rupture time of the safety test process are recorded and uploaded in real time, where the valve rupture time refers to the time when the status information of the lithium battery (such as current, voltage, etc.) exceeds the preset threshold.

[0103] S5. Monitor experimental phenomena during security testing in real time, and ensure timely updating and synchronization of these dynamically changing phenomena to ensure the continuity and accuracy of the test.

[0104] S6. After the safety test is completed, record the exact end time, take photos and upload the pictures / file information after the test is completed. Compare the difference between the actual end time and the expected completion time, deeply analyze the specific reasons for the time difference, and conduct a comprehensive evaluation of the test results.

[0105] S7. Confirm that the tested cell is removed and all test processes are completed.

[0106] For example, Figure 3 This can be used as an example of uploading pictures / files in this application. Specifically, firstly, the uploaded pictures / files are selected according to the path of the pictures / files, and it is determined whether the type of the uploaded pictures / files is correct. If so, the pictures / files are directly uploaded and saved.

[0107] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effect of the present application, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present application.
