Description

Technical Field

[0001] This invention relates to the field of charge and discharge testing technology, and in particular to an automatic operation method, system, equipment and medium for charge and discharge processes. Background Technology

[0002] After lithium batteries are manufactured, they need to undergo a series of charging and discharging tests. Before testing, charging and discharging procedures need to be programmed, and then the lithium batteries are controlled to charge and discharge based on these procedures. However, the traditional method of manually setting and operating the charging and discharging procedures has the following drawbacks:

[0003] 1. Manually performing protection checks during charging and discharging, such as voltage and current limits, is not only time-consuming and labor-intensive, but the repetitive nature of the work also puts a great strain on the patience of the testers; 2. It requires manual intervention and cannot be conducted at night; 3. The source data for the tests is difficult to obtain, which is not conducive to later traceability.

[0004] Therefore, how to provide an automated method, system, equipment, and medium for charging and discharging processes to improve the convenience, efficiency, and traceability of lithium battery testing has become an urgent technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic operation method, system, equipment and medium for charging and discharging steps, so as to improve the convenience, efficiency and traceability of lithium battery testing.

[0006] In a first aspect, the present invention provides an automatic operation method for charging and discharging processes, comprising the following steps:

[0007] Step S1: The host computer creates a step file based on several charging and discharging steps, and configures the test channel for lithium battery testing through Ranorex.

[0008] Step S2: The host computer automatically reads the process file through Ranorex and automatically executes each charge and discharge process in the process file sequentially through the test channel;

[0009] Step S3: The host computer acquires test data in real time during the execution of each charging and discharging step, and Ranorex monitors the channel status of the test channel in real time.

[0010] Step S4: Ranorex automatically reads the test data and compares the test data with the expected data carried in the charge and discharge process in real time to obtain the comparison results.

[0011] Step S5: The host computer generates a test report and archives it based on the charging and discharging steps, test data, and comparison results.

[0013] Furthermore, in step S1, the process file is an XML file.

[0014] Furthermore, step S4 specifically includes:

[0015] The host computer performs hash calculations on the charging and discharging steps, test data, comparison results, and test time to obtain hash values. It then uses the national cryptographic algorithm to encrypt the charging and discharging steps, test data, comparison results, test time, and hash values ​​to generate a test report. The test report is stored locally and then distributed and backed up to a cloud server.

[0016] Secondly, the present invention provides an automatic charging and discharging process system, comprising the following modules:

[0017] The process step file creation module is used by the host computer to create a process step file based on several charge and discharge process steps, and configure the test channel for lithium battery testing through Ranorex.

[0018] The charge / discharge step execution module is used by the host computer to automatically read the step file through Ranorex and execute each charge / discharge step in the step file sequentially through the test channel.

[0019] The test data acquisition module is used by the host computer to acquire test data in real time during the execution of each charging and discharging step, and Ranorex monitors the channel status of the test channel in real time.

[0020] The data comparison module is used by Ranorex to automatically read the test data and compare the test data with the expected data carried in the charge and discharge process in real time to obtain the comparison results.

[0021] The test report generation module is used by the host computer to generate and archive test reports based on the charging and discharging steps, test data, and comparison results.

[0022] Furthermore, in the process step file creation module, the charging and discharging process step includes at least the charging start time, charging current, charging end time, discharging start time, discharging current, discharging end time, test channel number, number of test cycles, upper voltage limit, upper current limit, and expected data.

[0023] Furthermore, in the process step file creation module, the process step file is an XML file.

[0024] Furthermore, the test report generation module is specifically used for:

[0025] The host computer performs hash calculations on the charging and discharging steps, test data, comparison results, and test time to obtain hash values. It then uses the national cryptographic algorithm to encrypt the charging and discharging steps, test data, comparison results, test time, and hash values ​​to generate a test report. The test report is stored locally and then distributed and backed up to a cloud server.

[0026] Thirdly, the present invention provides an automatic charging and discharging step operation device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method described in the first aspect.

[0029] 1. A process file is created using a host computer based on several charge / discharge steps. A test channel for lithium battery testing is configured using Ranorex. Ranorex then automatically reads the process file and executes each charge / discharge step sequentially through the test channel. During the execution of each charge / discharge step, test data is acquired in real time and compared with the actual charge / discharge steps to obtain comparison results. Finally, a test report is generated and archived based on the charge / discharge steps, test data, and comparison results. In other words, the process file is automatically executed using Ranorex without manual intervention. The archived test report facilitates later traceability, ultimately greatly improving the convenience, efficiency, and traceability of lithium battery testing.

[0030] 2. By performing hash calculations on the charging and discharging steps, test data, comparison results, and test time, a hash value is obtained. This hash value can then be used to verify the integrity of the charging and discharging steps, test data, comparison results, and test time, and to check for tampering. Furthermore, the charging and discharging steps, test data, comparison results, test time, and hash value are encrypted using national cryptographic algorithms to prevent the relevant data from being stolen in plaintext, thereby greatly improving the security of the test report.

[0031] 3. By storing test reports locally and distributing them to cloud servers, test reports can be recovered from local storage if they are lost, further enhancing the security of test reports.

[0039] The technical solution in this application embodiment has the following general idea: the process step file created by Ranorex is automatically executed without manual intervention, and the test report generated based on the charge and discharge process step, test data and comparison results is archived and backed up to improve the convenience, efficiency and traceability of lithium battery testing.

[0040] Example 1

[0041] This embodiment provides a method for automatically operating the charging and discharging process, such as... Figure 1 As shown, it includes the following steps:

[0042] Step S1: The host computer creates a step file based on several charging and discharging steps, and configures the test channel for lithium battery testing through Ranorex.

[0043] Step S2: The host computer automatically reads the process file through Ranorex and automatically executes each charge and discharge process in the process file sequentially through the test channel. Ranorex is a software that can record computer operations. After the recorded operation is completed, the recorded operation can be replayed to perform automated testing.

[0044] Step S3: The host computer acquires test data in real time during the execution of each charging and discharging step, and Ranorex monitors the channel status of the test channel in real time; the channel status includes at least whether the test has ended and whether there is an alarm.

[0045] Step S4: Ranorex automatically reads the test data and compares the test data with the expected data carried in the charge and discharge process in real time to obtain the comparison results.

[0046] Step S5: The host computer generates a test report and archives it based on the charging and discharging steps, test data, and comparison results.

[0047] This invention automatically executes the created process files using Ranorex, eliminating the need for manual intervention. It also archives the test reports generated based on the charge / discharge process, test data, and comparison results, facilitating later traceability. Ultimately, this greatly improves the convenience, efficiency, and traceability of lithium battery testing.

[0048] In step S1, the charging and discharging process includes at least the charging start time, charging current, charging end time, discharging start time, discharging current, discharging end time, test channel number, number of test cycles, upper voltage limit, upper current limit, and expected data.

[0049] In step S1, the process file is an XML file.

[0050] Step S4 specifically involves:

[0051] The host computer performs hash calculations on the charging and discharging steps, test data, comparison results, and test time to obtain hash values. It then uses the national cryptographic algorithm to encrypt the charging and discharging steps, test data, comparison results, test time, and hash values ​​to generate a test report. The test report is stored locally and then distributed and backed up to a cloud server.

[0052] Hash values ​​are obtained by hashing the charging / discharging steps, test data, comparison results, and test time. These hash values ​​are then used to verify the integrity of the charging / discharging steps, test data, comparison results, and test time, and to check for tampering. Furthermore, the charging / discharging steps, test data, comparison results, test time, and hash values ​​are encrypted using national cryptographic algorithms to prevent the data from being intercepted in plaintext, thus greatly enhancing the security of the test report. By storing the test report locally and distributing backups to a cloud server, the report can be recovered from the cloud server if the locally stored report is lost, further improving its security.

[0056] The charge / discharge step execution module is used by the host computer to automatically read the step file through Ranorex and execute each charge / discharge step in the step file sequentially through the test channel. Ranorex is a software that can record computer operations. After the recorded operation is completed, the recorded operation can be replayed to execute automated testing.

[0057] The test data acquisition module is used by the host computer to acquire test data in real time during the execution of each charging and discharging step. Ranorex monitors the channel status of the test channel in real time; the channel status includes at least whether the test has ended and whether there is an alarm.

[0058] The data comparison module is used by Ranorex to automatically read the test data and compare the test data with the expected data carried in the charge and discharge process in real time to obtain the comparison results.

[0059] The test report generation module is used by the host computer to generate and archive test reports based on the charging and discharging steps, test data, and comparison results.

[0060] This invention automatically executes the created process files using Ranorex, eliminating the need for manual intervention. It also archives the test reports generated based on the charge / discharge process, test data, and comparison results, facilitating later traceability. Ultimately, this greatly improves the convenience, efficiency, and traceability of lithium battery testing.

[0062] In the process step file creation module, the process step file is an XML file.

[0063] The test report generation module is specifically used for:

[0064] The host computer performs hash calculations on the charging and discharging steps, test data, comparison results, and test time to obtain hash values. It then uses the national cryptographic algorithm to encrypt the charging and discharging steps, test data, comparison results, test time, and hash values ​​to generate a test report. The test report is stored locally and then distributed and backed up to a cloud server.

[0065] Hash values ​​are obtained by hashing the charging / discharging steps, test data, comparison results, and test time. These hash values ​​are then used to verify the integrity of the charging / discharging steps, test data, comparison results, and test time, and to check for tampering. Furthermore, the charging / discharging steps, test data, comparison results, test time, and hash values ​​are encrypted using national cryptographic algorithms to prevent the data from being intercepted in plaintext, thus greatly enhancing the security of the test report.
