Description

Technical Field

[0001] The present application relates to the technical field of battery testing, and in particular to a battery cluster testing method, electronic equipment and storage medium. Background Art

[0002] The short circuit of the energy storage battery cluster is a safety abuse test that cannot be ignored during user use. It needs to be matched with the corresponding protection device fuse; whether the fuse can protect (fuse) the electrical components and batteries before all electrical components are damaged (overcurrent) and the length of time the fuse takes to blow determines the degree of damage to the electrical components.

[0003] In related technologies, fault analysis is performed to detect short circuits in energy storage battery clusters by judging signals such as capacity differences and minimum voltages, which is prone to omissions and low real-time detection results. In the current short-circuit detection technology that uses relays and fuses as protection objects, it often takes more than 10ms for the relay to disconnect, and when the current is too large, the relay may have been stuck, making it impossible to achieve safe protection of the battery system under short-circuit conditions.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0038] Embodiments of the present application provide a battery cluster testing method, an electronic device, and a storage medium.

[0039] Among them, the battery cluster testing method can be specifically applied to a terminal, which may include a tablet computer or a personal computer (PC). The terminal can establish a wired or wireless connection with a server, and the server may include an independently running server or a distributed server, or may include a server cluster consisting of multiple servers.

[0040] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0041] A battery cluster testing method comprises: obtaining current data of the battery cluster to be tested by means of a sensor installed on the battery cluster to be tested during the test; converting the current data into target data in a preset format based on a preset program; and displaying the test results of the battery cluster to be tested in an information display interface according to the target data and configuration information corresponding to the target data.

[0042] See also Figure 1 , Figure 1 A schematic diagram of a battery cluster testing method provided in an embodiment of the present application. The specific process of the battery cluster testing method may be as follows:

[0043] 101. When performing a test, current data of the battery cluster to be tested is obtained through a sensor installed on the battery cluster to be tested.

[0044] Among them, the sensor is used to obtain the current data of the battery cluster to be tested, and the sensor can be a current transformer, a fluxgate current sensor or a Hall sensor. Optionally, in some embodiments of the present application, the current data of the battery cluster to be tested is obtained by installing a Hall sensor on the battery cluster to be tested. For example, specifically, a Hall sensor with a large enough range is installed on the charging and discharging high-voltage harness of the battery cluster to ensure that the high current that may occur in the short-circuit test can be measured. Optionally, in some embodiments of the present application, a Hall sensor with a range of 20000A is used. The Hall sensor needs to be connected to the battery management system (BMS) and the data acquisition system. After ensuring that all safety measures are in place, the short-circuit test of the battery cluster is performed. In this process, the Hall sensor will monitor and record the current data passing through the battery cluster in real time. The current data collected by the Hall sensor is preliminarily processed by the BMS and sent to the data acquisition system through the controller area network (CAN) communication. These data can be recorded very accurately, with an accuracy of up to microseconds (0.000001 seconds).

[0045] Optionally, in some embodiments of the present application, the step of “obtaining current data of the battery cluster to be tested by means of a Hall sensor installed on the battery cluster to be tested during the test” may specifically include:

[0046] Perform a short-circuit test on the battery cluster to be tested, triggering the fuse action;

[0047] The current data of the battery cluster to be tested when each fuse is actuated is obtained through the sensor installed on the battery cluster to be tested.

[0048] Among them, a fuse is a circuit protection device that is mainly used to automatically cut off the current when the circuit is overloaded or short-circuited to protect the circuit and equipment from damage. The working principle of the fuse is to use a metal wire or metal sheet to melt under the heat generated by the overload current, thereby disconnecting the circuit.

[0049] First, install the Hall sensor on the charging and discharging high-voltage wiring harness of the battery cluster to measure the current during the short-circuit test. Then, install the fuse in the circuit of the battery cluster and ensure that the fuse is set to operate at a predetermined current threshold. Next, connect the Hall sensor to the battery management system (BMS) and data acquisition system so that the current data can be monitored and recorded in real time.

[0050] During the short-circuit test, the Hall sensor monitors the current of the battery cluster in real time and captures current data when each fuse is activated. The BMS records the current data collected by the Hall sensor, which will be used for subsequent analysis of the performance of the fuse.

[0051] By monitoring the current data when the fuse is operated, the performance of the fuse can be evaluated to ensure that they can provide the necessary protection at the critical moment.

[0052] 102. Convert the current data into target data in a preset format based on a preset program.

[0053] First, determine the format and structure of the target data. For example, if the target data needs to be displayed in the form of an Excel table, you need to define column names, such as "timestamp", "current value (A)", etc.; then, determine the accuracy and time interval of current data collection, for example, collect current data every 0.000001 seconds, and then receive current data from the BMS system through a preset program (such as Python), and process and convert it according to the preset format. Specifically, the current data is collected through the Hall sensor and the BMS system, and then processed using a preset program. Then, the processed data is converted to Excel format, and the converted data is exported as an Excel file.

[0054] 103. Display the test result of the battery cluster to be tested in the information display interface according to the target data and the configuration information corresponding to the target data.

[0055] The configuration information includes various parameters and settings related to the battery cluster short circuit test.

[0056] For example, specifically, determine the configuration information that needs to be displayed, such as the battery cluster model, test conditions, rated current of the fuse, etc. Then, further process the target data according to the actual needs of the user, such as calculating the average time and maximum current of the fuse action, etc. The processed target data and configuration information are displayed on the information display interface.

[0057] Optionally, in some embodiments of the present application, the step of “displaying the test results of the battery cluster to be tested in the information display interface according to the target data and the configuration information corresponding to the target data” may specifically include:

[0058] Extract the data format and data precision corresponding to the target data from the configuration information;

[0059] The test results of the battery cluster to be tested are displayed in the information display interface according to the target data, data format and data accuracy.

[0060] According to the configuration information, determine the format (such as time series, table, etc.) and precision (such as the precision of timestamp is 0.000001 seconds) of the target data. Use front-end technology (such as HTML, CSS, JavaScript) or specialized data display tools (such as Tableau, Power BI) to create an information display interface. Implement dynamic display of target data in the information display interface, allowing users to interactively view test results.

[0061] Optionally, in some embodiments of the present application, the step of “displaying the test results of the battery cluster to be tested in the information display interface according to the target data, data format and data accuracy” may specifically include:

[0062] Construct data display coordinate axes according to data format and data precision;

[0063] Get benchmark information;

[0064] The test results of the battery cluster to be tested are displayed in the information display interface according to the target data, the benchmark test information and the data display coordinate axis.

[0065] Among them, benchmark information generally refers to a set of standard values ​​obtained from a series of tests conducted under specific conditions. These standard values ​​can be used as reference points for subsequent tests to compare and evaluate the results of new tests. For example, specifically, the format (e.g., time series data) and accuracy (e.g., timestamp accuracy of 0.000001 seconds) of the current data are determined according to the configuration information. Then, the initial coordinate axis for data display is constructed through a preset icon library (such as D3.js, Chart.js or Plotly). According to the data accuracy, the labels, scales and ranges of the x-axis (e.g., timestamp) and y-axis (e.g., current value) are set, and the time format of the x-axis is matched with the data accuracy. At the same time, the benchmark information is obtained, and the benchmark information may include the average value, standard deviation or other statistical data of the historical test. Optionally, in some embodiments of the present application, the benchmark information is converted to the same format as the target data for comparison. Then, the target data (i.e., new test data) and the benchmark data are processed together to ensure that they are on the same time scale and numerical scale. Use the chart library to create a chart, set the coordinate axis, and use the target data and benchmark information as the data source of the chart. Display target data and benchmark information in a chart, using different colors or line styles to distinguish them.

[0066] Optionally, in some embodiments of the present application, the step of “displaying the test results of the battery cluster to be tested in the information display interface according to the target data, the benchmark test information and the data display coordinate axis” may specifically include:

[0067] Import the target data into the data display coordinate axis;

[0068] The target data of the data display coordinate axis is tested using the benchmark test information, and the test results of the battery cluster to be tested are displayed in the information display interface.

[0069] For example, specifically, ensure that the target data and benchmark data have been prepared in the same data format and precision. Build the coordinate axis for data display through the preset chart library, and set the labels, scales and ranges of the x-axis and y-axis according to the data format and data precision. Add the benchmark information to the chart as a reference line or data series, and distinguish the benchmark information and the target data with a specified color or line type. Then, compare the target data with the benchmark information to determine whether the target data is within an acceptable range. For example, you can set a threshold to determine whether the test results meet expectations. For example, if the current value exceeds a certain percentage of the benchmark value, the test is considered to have failed. Finally, display the test results in the information display interface.

[0070] Optionally, in some embodiments of the present application, the step of “testing the target data of the data display coordinate axis using the benchmark test information, and displaying the test results of the battery cluster to be tested in the information display interface” may specifically include:

[0071] Determine the test dimensions corresponding to the benchmark test information;

[0072] Under the test dimension, the target data of the data display coordinate axis is tested using the benchmark test information;

[0073] Mark the test results under different test dimensions in the information display interface.

[0074] For example, specifically, determine the test dimensions corresponding to the benchmark test information, such as current peak value, current size, voltage level, temperature, etc. in different time periods; for each test dimension, determine one or more benchmark values, and then compare the target data with the benchmark test information in each test dimension. Test the target data according to the set threshold and record the test results. Finally, use different colors or marks on the chart to represent the test results, such as Figure 2 As shown, in Figure 2 The information display interface includes test results of multiple different dimensions, which are marked by different color labels. Optionally, in some embodiments of the present application, when a test fails in a certain dimension, it can be displayed in a highlighted or jittered manner so that the user can be informed in time.

[0075] Optionally, in some embodiments of the present application, it further includes:

[0076] In response to a trigger operation on the tool item, an adjustment window is displayed in the information display interface;

[0077] In response to an adjustment operation on the adjustment window, the configuration information is adjusted.

[0078] Among them, the information display interface includes at least a tool item. Optionally, in some embodiments of the present application, such as Figure 3 As shown, the information display interface includes multiple menu items, one of which is a tool item. The user can trigger the display of an adjustment window in the information display interface by clicking the tool item. The adjustment window can be used to adjust the settings of the configuration information, such as the information of the coordinate axis, the time accuracy of the short-circuit test, and the dimension of the test, etc. The specific settings can be made according to the actual situation and will not be repeated here.

[0079] In the embodiment of the present application, when testing, the current data of the battery cluster to be tested is obtained by installing a sensor on the battery cluster to be tested, and then, based on a preset program, the current data is converted into target data in a preset format. Finally, according to the target data and the configuration information corresponding to the target data, the test results of the battery cluster to be tested are displayed in the information display interface. The battery cluster test solution provided by the present application, when testing, obtains the current data of the battery cluster to be tested by installing a sensor, and displays the test results of the battery cluster to be tested in the information display interface using the target data corresponding to the current data and the configuration information corresponding to the target data. Thus, when testing the battery cluster, the current data generated by the battery cluster during the short-circuit test is collected in real time by the sensor, and the current data is converted into target data in a preset format, which is convenient for analyzing the performance of the fuse and the safety characteristics of the battery cluster, thereby improving the reliability of the battery cluster test results.
