It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0102] Currently, battery modules often experience thermal runaway during use. This means that one or more of the multiple cells included in the battery module may experience thermal runaway. However, since the multiple cells are generally stacked and arranged, when one or more cells experience thermal runaway, the surrounding cells will be affected by the heat from the thermal runaway cell, thereby reducing the performance of the battery module or shortening its service life. Therefore, it is necessary to test the thermal diffusion performance of the battery module and, based on the test results, to study how to reduce the impact of the thermal runaway cells on the entire battery module. In related art, when testing the thermal diffusion performance of a battery module, different voltages or different heat levels are generally applied to the battery to be tested. During this process, temperature change data of the battery to be tested under different voltages or different heat levels is collected. Finally, the thermal diffusion performance of the battery module is determined by analyzing the temperature change data. This testing method requires actual testing of the thermal runaway battery to obtain test data for analysis, which requires the use of an excessive number of thermal runaway batteries for testing, greatly increasing the cost of battery testing. To address this issue, the present invention provides a battery testing method, which will be described in detail in the following embodiments.

The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be achieved through WIFI, a mobile cellular network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a battery testing method is implemented. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covering the display screen, or a button, trackball or touchpad provided on the computer device housing, or an external keyboard, touchpad or mouse.

[0104] Those skilled in the art will understand that Figure 1 The structure shown in the figure is only a block diagram of a part of the structure related to the solution of the present application, and does not constitute a limitation on the computer device to which the solution of the present application is applied. The specific computer device may include more or fewer components than shown in the figure, or combine certain components, or have a different component arrangement.

[0105] In one embodiment, Figure 2 As shown, a test method is provided to apply the method to Figure 1 The computer device in the example is used to illustrate the process, including the following steps:

[0106] S201 , responding to an input instruction triggered by a user on a test interface, obtaining attribute parameters of a battery to be tested.

[0107] The input command is used to obtain the property parameters of the battery under test entered by the user on the test interface, which contains the property parameters of the battery under test. The property parameters are relevant for calculating the thermal diffusion performance of the battery. The test interface is the interface of the test application or simulation software, for example, when using a test app to test the battery, the test interface of the test app. This test application or simulation software can realize the construction of a simulation model for the battery and perform testing based on the simulation model.

[0108] In an embodiment of the present application, a test application (e.g., a battery simulation APP) or simulation software is pre-installed on the computer device, and the test application or simulation software can be operated to simulate the battery, thereby guiding the design of the battery. When it is necessary to test a thermal runaway battery or a battery, a test application or simulation software for simulating the battery can be started on the computer device, and a test interface corresponding to the test application or simulation software can be displayed on the display screen of the computer device. The user can enter the attribute parameters of the battery to be tested on the test interface. After the user enters the attribute parameters, the computer device can generate an input instruction carrying the attribute parameters. The computer device can immediately respond to the input instruction triggered by the user on the test interface, parse the input instruction, extract the attribute parameters of the battery to be tested, and obtain the attribute parameters of the battery to be tested. Optionally, after the user enters the attribute parameters of the battery on the test interface, the computer device can also store the attribute parameters in a cache. When the computer device responds to the input instruction, the attribute parameters can be obtained from the cache according to the instruction of the input instruction.

[0109] S202 , responding to a test instruction triggered by the user on the test interface, inputting the attribute parameters into a heat estimation model for measurement, obtaining test data of the battery to be tested, and displaying the test data on the test interface.

[0110] Among them, the test instruction is used to start the test of the battery to be tested, that is, to test according to the property parameters and the heat estimation model, so as to realize the test of the simulated battery to be tested. The heat estimation model is used to measure the influence of the thermal diffusion of the battery according to the property parameters. The test data includes the temperature change data of the large surface of each thermal runaway cell in the battery to be tested and the temperature change data of the bottom surface of the cell. For example, the battery to be tested includes thermal runaway cell A and thermal runaway cell B. The test data includes the temperature change data of the large surface of the cell of thermal runaway cell A over time, the temperature change data of the bottom surface of the cell of thermal runaway cell A over time, the temperature change data of the large surface of the cell of thermal runaway cell B over time, and the temperature change data of the bottom surface of the cell of thermal runaway cell B over time. The heat estimation model can be pre-built and stored in a database, which can include various types of battery test models to provide calculation methods for battery performance testing. Optionally, the heat estimation model can be used to calculate the heat exchange heat group between the thermal runaway cell and the air in the battery under test, as well as to calculate the internal thermal resistance of the thermal runaway cell, so as to measure the thermal diffusion performance of the thermal runaway cell based on these two calculations.

[0111] Optionally, the heat estimation model can be determined using the following relationship (1):

[0112]

[0113] Among them, ρ represents the density of the battery cell, C pIndicates the specific heat capacity of the battery cell, T indicates the temperature of the battery cell, τ indicates the test time of the battery cell, represents the rate of change of temperature over time, k represents the thermal conductivity, Represents the self-generated heat of the battery cell. The density, specific heat capacity, self-generated heat capacity, and thermal conductivity of the battery cell are all attribute parameters of the battery cell, and the computer equipment can calculate the battery cell density and specific heat capacity based on some geometric parameters of the battery cell. For example, the battery cell density and specific heat capacity can be calculated based on the battery cell length, battery cell width, battery cell height, battery cell side shell thickness, battery cell large surface shell thickness, battery cell bottom shell thickness, etc. Optionally, the battery cell density, battery cell specific heat capacity, battery cell thermal conductivity, and self-generated heat capacity of the battery cell can also be determined based on the battery cell's description document.

[0114] In an embodiment of the present application, when the computer device obtains the property parameters of the battery to be tested based on the aforementioned steps, the user can trigger the generation of a test instruction on the test interface by clicking a control, voice input, or text input. Optionally, the test instruction can include an identifier of a heat estimation model. When the computer device responds to the test instruction triggered by the user on the test interface, the test instruction can be parsed to extract the identifier of the heat estimation model, and further search the database for the heat estimation model based on the identifier of the heat estimation model. The property parameters of the battery to be tested are input into the heat estimation model for measurement, and the temperature change data of each surface of the thermal runaway cell in the battery to be tested is measured, that is, the test data is obtained.

[0115] The test method described in the embodiment of the present application obtains the property parameters of the battery to be tested by responding to the input instructions triggered by the user on the test interface, and inputs the property parameters into the heat estimation model for measurement in response to the test instructions triggered by the user on the test interface, obtains the test data of the battery to be tested, and displays the test data on the test interface.

Compared with the traditional method of performing actual testing on the battery to be tested, the above method is a user-operable simulation test method that does not rely on the actual thermal runaway battery for testing. It can avoid the additional cost brought by design trial and error to a certain extent, and reduce the number of test experiments, thereby reducing the test cost of the battery to be tested and improving the test efficiency of the battery to be tested to a certain extent.

When the computer device displays test data on the test interface, it specifically performs the following steps: displaying the test data in the display area.

[0118] In an embodiment of the present application, when the computer device displays a test interface, the user can enter the property parameters of the battery to be tested in the operation area of the test interface. After the user enters the property parameters, the computer device can generate an input instruction carrying the property parameters. The computer device can immediately respond to the input instruction triggered by the user in the operation area, parse the input instruction, extract the property parameters of the battery to be tested, and obtain the property parameters of the battery to be tested. When the computer device obtains the property parameters of the battery to be tested based on the aforementioned steps, the user can click on the test control to trigger the generation of the test instruction. When the computer device responds to the test instruction, it can parse the test instruction, extract the identifier of the heat estimation model, and further search the database for the heat estimation model based on the identifier of the heat estimation model, and input the property parameters of the battery to be tested into the heat estimation model for measurement, and obtain the temperature change data of each surface on the thermal runaway cell in the battery to be tested, that is, obtain the test data. Then, the computer device can display the test data in the display area of the test interface so that the user can intuitively view the test results.

[0123] The operation area described in the embodiment of the present application divides and displays different types of attribute parameters, which makes it convenient for users to quickly input different types of parameters in the operation area when triggering input instructions based on the operation area, thereby improving testing efficiency.

[0124] In one embodiment, Figure 5As shown, a structure parameter area is provided, which includes a battery cell parameter area and a thermal insulation parameter area. Correspondingly, the structure parameters include battery cell parameters and thermal insulation pad parameters, and the structure parameter input instructions include battery cell parameter input instructions and thermal insulation parameter input instructions. When the computer device responds to the structure parameter input instruction triggered by the user in the structure parameter area, the computer device specifically executes the following steps: responding to the battery cell parameter input instruction triggered by the user in the battery cell parameter area, and responding to the thermal insulation parameter input instruction triggered by the user in the thermal insulation parameter area.

The cell parameter input instructions are used to instruct the computer device to obtain the cell parameters input by the user in the cell parameter area, and the thermal insulation parameter input instructions are used to instruct the computer device to obtain the thermal insulation pad parameters input by the user in the thermal insulation parameter area. The cell parameters are the structural parameters of some related cells of the battery to be tested, such as the length of the cell, the width of the cell, the height of the cell, the side shell thickness of the battery to be tested, the large shell thickness of the battery to be tested, the bottom shell thickness of the battery to be tested, etc.; the thermal insulation pad parameters are the structural parameters of some related thermal insulation pads of the battery to be tested, such as the options of the thermal insulation pad, the thickness of the thermal insulation pad, etc. The side shell thickness of the battery to be tested may be specifically the side aluminum shell thickness, the large shell thickness of the battery to be tested may be the large aluminum shell thickness, and the bottom shell thickness of the battery to be tested may be specifically the bottom aluminum shell thickness.

Optionally, the user can also use the thermal insulation pad selection item to determine whether to simulate a battery containing a thermal insulation pad. If the battery to be tested is a battery containing a thermal insulation pad, thermal insulation pads of different thicknesses can be set to simulate the battery; if the battery to be tested is a battery without a thermal insulation pad, the thickness of the thermal insulation pad is set to 0 to simulate the battery without a thermal insulation pad.

[0128] The operating area described in the embodiments of this application divides and displays different types of structural parameters, making it easier for users to quickly enter different types of parameters in the operating area when triggering input commands based on the operating area, thereby improving testing efficiency. In addition, the above operating area also provides a thermal insulation parameter area, which can be used to test the impact of different thermal insulation pads on the thermal diffusion of thermal runaway cells by setting different insulation pad sizes.

[0130] The drawing control is used to provide a control for user operation and to trigger a drawing instruction. The drawing control can be set within the structure parameter area or outside the structure parameter area.

[0131] In an embodiment of the present application, when a computer device displays a test interface, a user can click a drawing control to trigger the generation of a drawing instruction. When the computer device responds to the drawing instruction, it can parse the drawing instruction, extract the battery cell parameters and the thermal insulation pad parameters, and further construct a simulation model of the battery under test based on the battery cell parameters and the thermal insulation pad parameters, and display the simulation model of the battery under test in the display area of the test interface.

When the computer device responds to the drawing instruction, it can retrieve the structural parameters from the cache according to the instructions of the drawing instruction to build and display the simulation model.

[0132] By setting a drawing control on the test interface described in the embodiment of the present application, a simulation model of the battery to be tested can be automatically generated after the user inputs the battery cell parameters and the thermal insulation pad parameters, and the simulation model can be displayed on the test interface, so that the user can intuitively view the simulation model to verify the structure of the battery to be tested, and facilitate subsequent testing based on the correct simulation model of the battery to be tested, thereby improving test efficiency and accuracy.

[0133] In one embodiment, Figure 7 As shown, a heat generation parameter area is provided, which includes a temperature area and an import control. Correspondingly, the heat generation parameters include ambient temperature, maximum cell temperature, and heat generation performance parameters. The input instructions also include temperature parameter input instructions and import instructions. When the computer device responds to an input instruction triggered by a user in the operation area, it specifically executes the following steps: responding to the temperature parameter input instruction triggered by the user in the temperature area, and responding to the import instruction generated by the user triggering the import control. Optionally, the temperature area includes an edit box for the ambient temperature and an edit box for the maximum cell temperature.

[0134] Among them, the temperature area is used to provide some controls, buttons, edit boxes, etc. for user operation, so that the user can trigger the generation of temperature parameter input instructions in the temperature area; the import control is used to provide controls for user operation, used to trigger the import instruction, which can be set in the heat generation parameter area or outside the heat generation parameter area. The temperature parameter input instruction is used to instruct the computer device to obtain the ambient temperature and the maximum temperature of the battery cell input by the user in the temperature area, and the import instruction is used to instruct the computer device to obtain the heat generation performance parameters imported by the user triggering the import control. The ambient temperature is the temperature of the environment where the battery to be tested is located, and the maximum temperature of the battery cell is the temperature parameter required for calculating the heat generation performance. The calculation of the heat generation performance parameters requires some related parameters for the heat generation performance, which can be pre-recorded in a document or file and saved to a database.

[0135] In an embodiment of the present application, when a computer device displays a test interface, a user can enter the ambient temperature of the battery to be tested and the maximum cell temperature in the temperature area of the test interface. The computer device can generate a temperature parameter input instruction carrying the ambient temperature and the maximum cell temperature. The computer device can immediately respond to the temperature parameter input instruction, parse the temperature parameter input instruction, extract the ambient temperature and the maximum cell temperature of the battery to be tested, and obtain the ambient temperature and the maximum cell temperature of the battery to be tested. The user can also click on the import control to trigger the generation of an import instruction. When the computer device responds to the import instruction, it can parse the import instruction, extract the path of the file or document, and further search the database for the file or document containing the heat generation performance parameters based on the path.

[0136] The heat generation parameter area described in the embodiments of the present application divides and displays different types of heat generation parameters, making it easier for users to quickly enter different types of heat generation parameters within the heat generation parameter area when triggering input commands based on the heat generation parameter area, thereby improving testing efficiency. Furthermore, an import control is provided within the heat generation parameter area, allowing for direct file import, allowing for rapid input of large amounts of data within the heat generation parameter area, thereby improving testing efficiency.

[0137] In one embodiment, Figure 8 As shown, another operation area is provided, which also includes: a post-processing area. Correspondingly, the computer device can also respond to the processing instructions triggered by the user in the post-processing area, process the test data of the battery to be tested, obtain the temperature cloud map of the battery to be tested, and display the temperature cloud map on the test interface.

[0138] The post-processing area provides user-accessible controls, buttons, and edit boxes, allowing users to trigger and generate processing instructions within the post-processing area. These instructions instruct the computer to process the test data to obtain the test results desired by the user. The temperature cloud chart graphically displays the temperature variations of the various surfaces, sides, and bottoms of the battery under test, allowing users to intuitively view temperature variations or heat diffusion during thermal runaway.

[0139] In an embodiment of the present application, when a computer device measures a battery to be tested and obtains test data, a user can input some relevant setting parameters required for a cloud map in a post-processing area, thereby triggering the generation of a processing instruction. When the computer device responds to the processing instruction, it can parse the processing instruction, extract the relevant setting parameters of the cloud map therefrom, and further construct a temperature cloud map of the battery to be tested based on the relevant setting parameters of the cloud map and in combination with the test data, and display the temperature cloud map of the battery to be tested in the display area of the test interface.

[0140] The operation area described in the embodiment of the present application realizes post-processing of the test data by setting a post-processing area, and can display the test data to the user through the dimension of the cloud map, so that the user can intuitively view and analyze the test results, which can improve the applicability and test efficiency of the test application to a certain extent.

[0141] Optional, Figure 8 The post-processing area in the test flow includes a first time frame and a temperature cloud map control. Correspondingly, the processing instruction includes a first time setting instruction and a temperature cloud map generation instruction. When the computer device responds to the processing instruction triggered by the user in the post-processing area, processes the test data of the battery to be tested, obtains the temperature cloud map of the battery to be tested, and displays the temperature cloud map on the test interface, it specifically executes:

[0142] When it is detected that the temperature cloud map control is triggered, a temperature cloud map generation instruction is generated, and the test data of the battery to be tested is processed to obtain a temperature cloud map of the battery to be tested; in response to a first time setting instruction triggered by the user within a first time frame, according to the first display time indicated by the first time setting instruction, a temperature cloud map corresponding to the first display time is obtained, and the temperature cloud map corresponding to the first display time is displayed on the test interface.

[0143] The first time box is used to set the time to display the temperature cloud map. For example, the temperature cloud map at the 10th second can be displayed. This can be achieved by setting a corresponding edit box or drop-down menu type control in the post-processing area. The temperature cloud map control is used to instruct the computer device to analyze and post-process the test data and generate all temperature cloud maps of the battery under test within a preset time period, such as a temperature cloud map within 1 minute.

[0144] In the implementation of this application, the user can trigger the temperature cloud map control in the post-processing area, and the computer device can generate a temperature cloud map generation instruction, that is, the computer device immediately analyzes and processes the test data of the battery to be tested, and obtains the temperature cloud map of the battery to be tested at each time point within the preset time period. Then, the computer device can dynamically display the temperature cloud map at each time point on the test interface, for example, dynamically display all temperature cloud maps within 20s in chronological order. Optionally, the user can enter the first display time in the first time box in the post-processing area, and the computer device can generate a first time setting instruction. The computer device can extract the first display time from the first time setting instruction, and then obtain the temperature cloud map corresponding to the first display time from the temperature cloud map at each time point, and display the temperature cloud map corresponding to the first display time on the test interface.

[0145] Optional, Figure 8The post-processing area in the program further includes a second time frame and a cross-section cloud map control; the processing instruction further includes a second time setting instruction and a cross-section cloud map generation instruction; the computer device processes the test data of the battery to be tested in response to the cross-section cloud map generation instruction generated by the user triggering the cross-section cloud map control to obtain a cross-section cloud map of the battery to be tested;

[0146] In response to a second time setting instruction triggered by the user within a second time frame, the section cloud map corresponding to the second display time is obtained according to the second display time indicated by the second time setting instruction, and the section cloud map corresponding to the second display time is displayed on the test interface.

[0147] The second time frame is used to set the time for displaying the cross-section cloud image. For example, to display the cross-section cloud image at the 10th second, this can be achieved by setting a corresponding edit box or drop-down menu type control in the post-processing area. The cross-section cloud image control is used to instruct the computer equipment to analyze and post-process the test data and generate all cross-section cloud images of the battery under test within a preset time period, for example, a cross-section cloud image within 1 minute.

[0148] In the implementation of this application, the user can trigger the section cloud map control in the post-processing area, and the computer device can generate a section cloud map generation instruction, that is, the computer device immediately analyzes and processes the test data of the battery to be tested, and obtains the section cloud map of the battery to be tested at each time point within the preset time period. Then, the computer device can dynamically display the section cloud map at each time point on the test interface, for example, dynamically display all section cloud maps within 20s in chronological order. Optionally, the user can enter the second display time in the second time box in the post-processing area, and the computer device can generate a second time setting instruction. The computer device can extract the second display time from the second time setting instruction, and then obtain the section cloud map corresponding to the second display time from the section cloud map at each time point, and display the section cloud map corresponding to the second display time on the test interface.

[0149] Optional, Figure 8 The post-processing area in the test further includes a section height control; the processing instruction further includes a height setting instruction; the computer device executes the step of "acquiring a section cloud map corresponding to the second display time according to the second display time indicated by the second time setting instruction, and displaying the section cloud map corresponding to the second display time on the test interface" including:

[0150] In response to the height setting instruction generated by the section height control triggered by the user, the section cloud map corresponding to the second display time and height is obtained according to the height indicated by the height setting instruction and the second display time indicated by the second time setting instruction, and the section cloud map is displayed on the test interface.

[0151] The slice height control is used to provide a user-operated control for triggering a height setting instruction, which can be set in the post-processing area. The trigger height setting instruction carries the height of the slice cloud image to be displayed, which can be determined according to user needs.

[0152] In the implementation of this application, the user can trigger the section height control in the post-processing area, and the computer device can generate a height setting instruction. The computer device can extract the height of the displayed section cloud map from the height setting instruction, and then obtain the section cloud map corresponding to the second display time from the section cloud map at each time point, and then search for the section cloud map corresponding to the height from the section cloud map corresponding to the second display time, and display the section cloud map corresponding to the height on the test interface.

[0153] The operating area described in the embodiment of the present application sets a post-processing area to post-process the test data obtained after measurement, thereby obtaining a temperature cloud map or a cross-sectional cloud map of the overall structure of the battery to be tested, and displaying the test results from another dimension, so as to facilitate users to conduct further analysis and research based on the test results, thereby improving the applicability of the application in which the test interface described in the embodiment of the present application is located.

[0154] In one embodiment, Figure 9 As shown, the test interface also includes an analysis control. Correspondingly, the computer device can also respond to the analysis instruction generated by the user triggering the analysis control, perform curve fitting on the test data of the battery to be tested, generate a test curve of the battery to be tested, and display the test curve on the test interface.

[0155] The analysis control is used to provide a control for user operation and to trigger analysis instructions. It can be set in the operation area or outside the operation area.

[0156] In an embodiment of the present application, when the computer device displays a test interface, the user can click on the analysis control to trigger the generation of an analysis instruction. When the computer device responds to the analysis instruction, it can parse the analysis instruction and further analyze the test data based on the test data indicated by the analysis instruction to perform curve fitting to obtain a test curve of the battery to be tested, and display the test curve of the battery to be tested in the display area of the test interface.

[0157] By setting an analysis control on the test interface described in the embodiment of the present application, the test data can be automatically analyzed and curve-fitted after the computer device measures the battery to be tested, and the fitted curve can be displayed on the test interface, which allows users to intuitively view the test results through the curve dimensions.

[0158] In one embodiment, Figure 10As shown, the test interface also includes a report generation control. Correspondingly, the computer device can also respond to the report generation instruction generated by the user triggering the report generation control to generate a test report based on the test data, the temperature cloud map within the first display time and the test curve.

[0159] The report generation control is used to provide a user-operated control for triggering a report generation instruction, and can be set within or outside the operation area. The report generation instruction is also used to indicate the acquisition path of test data, temperature cloud maps, test curves, attribute parameters, and other data or parameters related to the test of the battery to be tested. Optionally, the report generation instruction carries the identification of the test data of the battery to be tested, the identification of the temperature cloud map corresponding to the first display time, and the identification of the test curve.

[0160] In the embodiment of the present application, when the computer device displays the test interface, the user can click the report generation control to trigger the generation of the report generation instruction. When the computer device responds to the report generation instruction, the report generation instruction can be parsed to extract the identification of the test data of the battery to be tested, the identification of the temperature cloud map corresponding to the first display time, and the identification of the test curve. According to these identifications, the data or cloud map or curve corresponding to these identifications are obtained from the database or related storage file, and then a test report is generated according to these data (for example, see Figure 11 The test report includes test data of the battery under test, a temperature cloud corresponding to the first display time, and a test curve. Optionally, the computer device may also obtain attribute parameters of the battery under test according to the report generation instruction and record them in the test report. Optionally, the test report also includes a navigation directory, and the navigation directory is used to indicate the search path or display path for each item included in the test report.

[0161] By setting a report generation control on the test interface described in the embodiment of the present application, a test report can be automatically generated based on the test data or other test results after the computer device measures the battery to be tested, which can facilitate users to perform statistical analysis and organization of the test data, thereby improving the functional diversity of this test application.

[0162] In one embodiment, Figure 10 The test interface shown also includes a save control. Correspondingly, the computer device can also respond to the save instruction generated by the user triggering the save control and store the test report in a file under the save path indicated by the save instruction.

[0163] The save control is used to provide a user-operated control for triggering a report save instruction. It can be set within or outside the operation area. The save instruction is also used to indicate the save path of the test report. Optionally, the save instruction carries the save path of the test report. Optionally, the test interface may also include a path input box for setting the save path, which can be edited and entered by the user or entered through a drop-down menu.

[0164] In an embodiment of the present application, when the computer device displays a test interface, the user can click a save control to trigger the generation of a save instruction. When the computer device responds to the save instruction, it can parse the save instruction, extract the save path of the test report, and save the test report corresponding to the test data to a related file under the save path, so that the user can quickly obtain the test report directly from the file under the save path when viewing it. Optionally, the computer device can also directly save the test data to a related file under the save path, so that the user can quickly obtain the test data directly from the file under the save path when viewing it.

[0165] By setting a save control on the test interface described in the embodiment of the present application, the test report can be automatically saved after the computer device measures and generates a test report for the battery under test, allowing the user to quickly view the test report. In addition, the test report includes test data, temperature cloud maps, and data on various dimensions of property parameters, fully displaying the test results, allowing the user to accurately analyze and study the thermal diffusion performance of the battery under test based on the test report.

[0166] In one embodiment, a display area is also provided, such as Figure 12 As shown, the display area includes at least one of a data display area, a graphic display area, and a curve display area (the display area shown in the figure is only an example); wherein the data display area is used to display the test data of the battery to be tested; the graphic display area is used to display relevant graphics of the battery to be tested; the relevant graphics include a simulation model of the battery to be tested, a temperature cloud map, and a cross-section cloud map; the curve display area is used to display the test curve of the battery to be tested.

[0167] When displaying the temperature cloud map, the graphic display area can also display a temperature bar, which is used to represent the display colors corresponding to different temperatures, that is, the temperature cloud map can be rendered and displayed using various colors, and different colors represent different temperatures, so that users can intuitively view the temperature changes of the thermal runaway cells of the battery to be tested, that is, the thermal diffusion of the thermal runaway cells. When the curve display area displays the test curve of the test data, the computer device can also mark the key data therein after generating the test curve, and display the curve and the annotations thereon at the same time when displaying. The key data can be extracted from the test data or calculated from the test data. For example, the key data can be the thermal diffusion time of the thermal runaway cell, and the thermal diffusion time can be calculated by the computer device based on the time period corresponding to the time point from the start to the end of the heat diffusion of the thermal runaway cell in the test data; optionally, the key data can also be the test data before the different temperature inflection points on the test curve.

[0168] The display area described in the embodiment of the present application can display the test results of the battery to be tested in various forms, and can also display the analysis results of the test data, which not only provides convenience for the test, but also provides the intelligence of the application used in the test method provided by the present application.

If the test data is curve fitted, a test curve of the battery to be tested is obtained, and the test area is displayed in the display area.

Figure 15The following are the test curves corresponding to another type of thermal insulation pad with a total thickness of 6.3mm. The test curves include the curves calculated using the simulated test application and the curves obtained by actual measurement of the battery to be tested. The comparison shows that the cooling trend after the thermal runaway of the battery cell is consistent with the actual measurement, and the thermal resistance of the heat exchange between the battery cell and the air in the simulation model is accurately calculated; the large surface temperature and side temperature of the battery cell during thermal runaway are consistent with the actual measurement, and the internal thermal resistance of the battery cell is accurately calculated.

Moreover, the test application can efficiently perform measurements under different thicknesses of thermal insulation pads, that is, it can study the effect of thermal insulation pads of different thicknesses on the thermal diffusion of thermal runaway cells. This means that the test application described in the present application can set different conditions (for example, thermal insulation pads of different thicknesses, cells of different widths, cells of different thicknesses, different charge and discharge powers, etc.) according to the different needs of users to accurately test the heat generation performance or thermal diffusion performance of the battery to be tested, thereby improving the intelligence of the test application.
