Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a method for generating a battery test flow according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a generation method of a battery test flow, where the generation method includes steps S110 to S130.
In step S110, relevant data regarding the battery test is acquired.
Optionally, the relevant data related to the battery test includes template selection information, parameters corresponding to the boundary conditions, and parameters related to the battery to be tested. The template, the parameters corresponding to the boundary conditions, and the parameters related to the battery to be tested are all related to the specific type of the battery test to be performed, and when different types of battery tests are performed, the selected information of the template, the parameters corresponding to the boundary conditions, and the parameters of the battery to be tested are different.
After the user has determined the particular type of battery test to be performed, the desired relevant data may be identified directly from the acquired user input information. The user input information may directly include template selection information, parameters corresponding to the boundary conditions, and parameters related to the battery to be tested.
The template selection information may also be determined indirectly by user input information. For example, when the information input by the user only contains a test name, the test name may be identified and the template required for the test may be automatically determined.
The relevant boundary conditions may be preset in the template, and when the template is selected, the relevant boundary conditions may also be automatically determined, and the relevant boundary conditions and parameters corresponding to the boundary conditions may also be indirectly determined by user input information, for example, the corresponding boundary conditions and parameters corresponding to the boundary conditions may be determined by a test name in the user input information.
And the parameters corresponding to the boundary conditions are mainly used for determining the jump, interruption and/or ending of the test process of the battery to be tested. For example, the parameter corresponding to the boundary condition may be a maximum temperature that the battery is allowed to reach, and in the test process, if the battery temperature reaches the maximum temperature, different steps may be executed next according to different experimental procedures, for example, when it is considered that a test skip condition is satisfied, a jump may be made to another step to continue the operation, or it is considered that a dangerous state is currently reached, the battery test procedure needs to be interrupted, and it is determined whether the battery test can be continued after a test person performs an inspection, or a high-risk state is currently reached or a test completion condition is reached, so that a test termination, an alarm process, and the like need to be performed.
The parameters of the battery to be tested can also be directly identified from the user input information.
Optionally, the parameters corresponding to the boundary conditions and the parameters related to the battery to be tested may also be directly read from the DBC file by obtaining the DBC file.
Among them, a DBC file (Database CAN file) is a file for describing data communication between CAN network nodes, and is generally provided by an automobile manufacturer.
Optionally, when the parameters corresponding to the boundary conditions and/or the parameters related to the battery to be tested are obtained by using the DBC file, it is considered that different automobile manufacturers have different settings for the variable names of the same parameter (for example, the maximum temperature, the minimum temperature, and the like), so the embodiment of the present invention further provides a mapping file, and names of the same parameter in different DBC files are uniformly mapped to the same variable name through the mapping file.
Optionally, the mapping file may be a table format document, and in the parameter name mapping process, the table format document is read and queried, so that the parameter names are unified.
The mapping file is an editable file, and the newly found mapping relation between the variable name and the uniform variable name corresponding to the parameter provided by the automobile manufacturer can be newly added into the mapping file.
Exemplarily, the mapping process in the DBC file corresponding to the battery a is shown in the following table 1, and the DBC signal name mapping process for the battery B is shown in table 2.
TABLE 1
| Serial number | Battery A DBC Signal name | Means for | Mapping |
|
| 1 | BMS_452_CELL_VOLT_MAX | Maximum cell voltage of | Vmax | |
| 2 | BMS_452_CELL_VOLT_MIN | Minimum cell voltage of | Vmin | |
| 3 | BMS_453_CELL_TEMP_MAX | Maximum cell temperature of | Tmax | |
| 4 | BMS_453_CELL_TEMP_MIN | Minimum cell temperature of battery a | Tmin |
TABLE 2
By adopting the technical scheme provided by the embodiment of the invention, the mapping file with the function of mapping parameter names is adopted, the universality and the automation degree of the technical scheme provided by the invention can be improved, and after the DBC file is loaded, the relevant parameters (including the parameters corresponding to the boundary conditions and the parameters of the battery to be tested) required by the battery test can be automatically identified.
In step S120, a selected template is called from at least one template stored in advance according to the template selection information.
Optionally, the pre-stored template may include one or more of: national standards-based templates, international standards-based templates, enterprise standards-based templates, and custom templates.
After determining template selection information, directly or indirectly, based on user input information, an appropriate template may be automatically recalled from the pre-stored templates.
Optionally, when the called template does not meet the current battery test requirement, appropriate editing may be performed on the basis of the called template, so that the edited template meets the current battery test requirement.
Furthermore, the edited template can be used as a new template for storage, and the template can be directly called without re-editing when the same battery test requirements are met in the future, so that the workload of testers is reduced.
In step S130, a test procedure is generated based on the selected template.
In step S140, a test procedure of the battery to be tested is determined according to the test step, the parameters corresponding to the boundary condition, and the parameters related to the battery to be tested.
The pre-stored data in the pre-stored template are all general data meeting the relevant standard, and the data related to the battery to be tested needs to be filled in according to the acquired data, so that a complete test flow aiming at the battery to be tested can be automatically generated after the test process step is determined and the parameters corresponding to the relevant boundary conditions and the data of the battery to be tested are written in.
According to the technical scheme provided by the embodiment of the invention, when battery systems of different types can be tested by adopting the same standard, the working step is not required to be rewritten, the testing working step is automatically generated according to the selected template and is converted into the testing flow, the battery testing efficiency and the reproducibility of the testing flow are improved, and the work of testing personnel can be simplified.
The method for generating a battery test flow according to the embodiment of the present invention will be explained in detail with reference to an embodiment.
Taking national standard-based templates as an example, the contents shown in fig. 2a and 2b are described in document "lithium ion power storage battery pack for electric vehicle and second part high energy application test procedure" of GB T31467.2-2015, and for the provisions of this part, national standard-based templates as shown in table 3 may be stored in advance:
TABLE 3
After the template shown in table 3 is selected, it can be determined that parameters such as recommended current, specified discharge cutoff voltage, rated capacity, and the like need to be supplemented according to the actual battery to be measured. Table 4 shows parameters corresponding to some boundary conditions that need to be filled in, and parameters related to the battery to be tested:
TABLE 4
After filling the parameters corresponding to the boundary conditions and the parameters related to the battery to be tested, the completed template as shown in table 5 can be obtained:
TABLE 5
According to table 5, an executable test flow related to the battery to be tested can be automatically generated, and when the battery to be tested is subsequently tested, the battery to be tested can be automatically tested directly according to the test flow.
