[0042] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0043] In this application, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] As the background technology shows, each manufacturer has its own database files, and the name of this database may be different in different versions of the BMS controller. Therefore, the host computer project used for hardware HIL testing needs to be modified to meet the different versions of the BMS controller, resulting in low efficiency of BMS controller HIL testing.

[0045] To address the aforementioned issues, this application discloses a hardware-in-the-loop (HIL) testing method and related equipment for a battery management system (BMS) controller. By mapping system variables, the method directly controls the execution of an automated HIL testing program, enabling hardware HIL testing of different versions of the BMS controller without requiring modifications to the test project. This not only improves the testing efficiency of BMS controller HIL testing but also avoids errors in test case modification due to different parameter settings from different manufacturers, thereby increasing the accuracy of BMS controller HIL testing.

[0046] It should be noted that the hardware-in-the-loop testing method and related equipment for a battery management system controller provided in this application can be used in the fields of energy storage and other technologies. The above is only an example and does not limit the application field of the hardware-in-the-loop testing method and related equipment for a battery management system controller provided in this application.

[0047] refer to Figure 1 The image shows a hardware-in-the-loop testing method for a battery management system controller disclosed in this application. The hardware-in-the-loop testing method for the battery management system controller mainly includes the following steps:

[0048] S101: Creates system variables for the BMS system.

[0049] In S101, system variables for the BMS system are created in the test control execution software, which runs on the equipment manufacturer's host computer.

[0050] Among them, the BMS system is an intelligent system that integrates sensors, control algorithms, and actuators. It achieves safety protection, performance improvement, and life extension by monitoring, controlling, and optimizing the operating status of the battery pack in real time.

[0051] System variables in a BMS system include, but are not limited to, voltage monitoring variables, current measurement variables, and temperature detection variables.

[0052] The host computer contains test control execution software. This software is used to control all hardware in the BMS HIL test system via Controller Area Network (CAN), Ethernet, or other means, and to perform tests and record data.

[0053] A schematic diagram of the BMS HIL testing system is shown below. Figure 2 As shown. The BMS HIL test system includes a low-voltage power supply module, input / output (I / O) modules, a battery simulator, a high-voltage power supply, a current source, a device under test (DUT) placement box, and a communication module.

[0054] The low-voltage power supply module is used to provide power to the BMS system so that the BMS system can work properly.

[0055] The I / O module is used to provide the necessary I / O signals to the BMS system.

[0056] The battery simulator is used to provide the BMS system with signals such as cell voltage and temperature.

[0057] The high-voltage power supply is used to provide the total battery voltage signal to the BMS system.

[0058] The current source is used to provide the total battery voltage signal to the BMS system.

[0059] The test box is used to hold the BMS controller that needs to be tested.

[0060] The communication module provides the necessary CAN communication interface and Ethernet control interface to the BMS and peripheral devices such as power supplies and simulators.

[0061] The CAN communication interface includes CAN_1, CAN_2 and CAN_3 communication interfaces.

[0062] Both the CAN_1 and CAN_2 communication interfaces are used to monitor CAN messages on the BMS system.

[0063] The CAN_3 communication interface is used to control hardware that requires CAN control in the BMS HIL test system through a host computer software, including but not limited to low-voltage power supply modules, battery simulators, etc.

[0064] The Ethernet control interface includes the ETH_1 interface and the ETH_2 interface.

[0065] The ETH_1 interface is used to establish Ethernet communication with the BMS system.

[0066] The ETH_2 interface is used to control Ethernet-controlled hardware in the BMS HIL test system, such as I / O modules, high-voltage power supplies, and current sources, via a host computer control software. This allows for the control of all hardware resources in the BMS HIL test system through a single host computer, facilitating subsequent automation and improving testing efficiency.

[0067] S102: Import system variables into the test project editing software and map the system variables to the databases of different controllers in the automated HIL test program.

[0068] After mapping the system variables to the databases of different controllers in the automated hardware-in-the-loop test program, the automated hardware-in-the-loop test program controls the system variables to control the hardware output test data required for the test items; among which, the test data includes at least voltage and temperature.

[0069] In the test control execution software, variables are created for mapping with different controller databases. By mapping with different controller databases, objects can be manipulated directly without writing complex database statements, avoiding data inconsistency issues caused by manually operating different controller databases.

[0070] The process of writing automated HIL test programs for different controller databases is as follows:

[0071] The variables created in the test control execution software are imported into the test project editing software. Following the test items and procedures required in "GB_T 34131-2023 Battery Management System for Power Energy Storage", an automated test program is written using the test project editing software. This automated test program only needs to be written once and can be directly reused in other projects, thereby improving the development efficiency of the automated test program.

[0072] Specifically, this involves importing system variables into the test project editing software and mapping these system variables to the databases of different controllers in the automated HIL test program, such as...Figure 3 As shown, the main steps include the following:

[0073] S301: Import system variables into the test project editing software, which runs on the equipment manufacturer's host computer.

[0074] The host computer also includes test project editing software. This software is designed to write each step as a script, based on the program control flow, outlining its function and steps.

[0075] S302: In the test project editing software, the variables are mapped to the database tables involved in the databases of different controllers in the automated hardware-in-the-loop test program; wherein, the database tables defined for the battery management system are different for different controllers.

[0076] The beneficial effects of this embodiment are as follows: By importing system variables into the test project editing software and mapping the system variables with the databases of different controllers in the automated hardware-in-the-loop test program, objects can be directly manipulated without writing complex database statements, avoiding data inconsistency problems caused by manually operating the databases of different controllers, reducing the amount of code and reducing code error efficiency, thereby improving development efficiency, accuracy and ensuring data consistency.

[0077] S103: Enables the automated hardware-in-the-loop test program to execute the corresponding test cases by controlling system variables.

[0078] In S103, the automated test program written in the test project editing software is imported into the test control execution software. The test projects to be executed are set in the configuration window of the test control execution software, and then the hardware-in-the-loop test is started.

[0079] Specifically, this involves the automated hardware variable control-in-the-loop test program executing the corresponding test cases by controlling system variables, such as... Figure 4 As shown. The main steps include the following:

[0080] S401: Operate on the corresponding database table through system variables to assign values ​​and read parameters in the database table, wherein the database table matches the test cases involved in the automated hardware-in-the-loop test program.

[0081] The test cases for different test items are the coded representations of the manual operation steps for these test items in a specific sequence. Using the test case library, before hardware-in-the-loop testing, operators only need to complete the matching with the manufacturer's parameters and signals, click the "Start Run Test Case" switch, and wait for the test cases to complete. No further operation is required during test case execution, reducing operator workload and improving testing efficiency.

[0082] S402: When a test item to be executed is detected in the configuration window of the automated hardware-in-the-loop test program, the automated hardware-in-the-loop test program runs the corresponding test cases based on the parameters in the database table, and confirms whether the controller device detection is correct through the mapped system variables, so as to realize the hardware-in-the-loop test of the corresponding controller device.

[0083] It should be noted that all test cases in the test case library are written using variables. The test cases do not involve specific signals. All assignments of manufacturer thresholds and manufacturer signals are done in the host computer software. This avoids the problem of modifying test cases incorrectly when changing parameters from different manufacturers, and improves the accuracy of hardware-in-the-loop testing.

[0084] The correctness of the controller device detection is confirmed by using the mapped system variables. Specifically, the correctness of the controller device detection is confirmed by checking whether the set value of the system variable matches the feedback value of the controller device. If the set value of the system variable matches the feedback value of the controller device, the controller device detection is confirmed to be correct. If the set value of the system variable does not match the feedback value of the controller device, the controller device detection is confirmed to be incorrect.

[0085] During hardware-in-the-loop testing, test data can be displayed in real time.

[0086] Obtain test data after test case execution, analyze the test data, and generate a corresponding test report with one click after the test is completed; the test report shall include at least the set values ​​of system variables and the feedback values ​​of controller devices.

[0087] The beneficial effects of this embodiment are as follows: Before hardware-in-the-loop testing, operators only need to complete the matching with the manufacturer's parameters and signals, click the "Start Test Case" switch, and wait for the test cases to complete. No operation is required during the execution of the test cases, reducing the operator's workload and improving testing efficiency. Furthermore, all test cases in the test case library are written using variables; the test cases do not involve specific signals. All assignments related to manufacturer thresholds and signals are done in the host computer software, avoiding the problem of incorrect test case modifications when changing parameters from different manufacturers, thus improving the accuracy of hardware-in-the-loop testing.

[0088] This application addresses the issue of spending considerable time modifying test programs for the same test items in the "GB_T 34131-2023 Battery Management System for Electric Energy Storage" standard across different energy storage BMS systems, and helps testers complete closed-loop testing effectively and quickly.

[0089] The beneficial effects of the method embodiments of this application are as follows: By mapping system variables, the operation of the automated hardware-in-the-loop test program can be directly controlled. The test project can meet the hardware HIL test of different versions of BMS controllers without modification. This not only improves the test efficiency of BMS controller HIL test, but also avoids the problem of incorrect test case changes due to different parameter settings of different manufacturers, thus improving the accuracy of BMS controller HIL test.

[0098] The variable mapping subunit is used to map variables to database tables involved in the databases of different controllers in the automated hardware-in-the-loop test program within the test project editing software; wherein, different controllers define different database tables for the battery management system.

[0099] Furthermore, the control execution unit 503 includes:

[0100] The operation subunit is used to operate on the corresponding database table through system variables, so as to assign values ​​and read parameters in the database table. The database table is matched with the test cases involved in the automated hardware-in-the-loop test program.

[0101] The test run subunit is used to run the corresponding test cases of the automated hardware-in-the-loop test program based on the parameters in the database table when a test item to be executed is detected in the configuration window of the automated hardware-in-the-loop test program. The system variables are then mapped to confirm whether the controller device detection is correct, thereby realizing the hardware-in-the-loop test of the corresponding controller device.

[0102] Furthermore, the controller hardware-in-the-loop testing apparatus also includes:

[0103] The control unit is used to map system variables to the databases of different controllers in the automated hardware-in-the-loop test program, and then, after the automated hardware-in-the-loop test program runs, control the system variables to control the hardware output test data required for the test items; wherein, the test data includes at least voltage and temperature.

[0107] The beneficial effects of the device embodiments of this application are as follows: By mapping system variables, the operation of the automated hardware-in-the-loop test program can be directly controlled. The test project can meet the hardware HIL test of different versions of BMS controllers without modification. This not only improves the test efficiency of BMS controller HIL test, but also avoids the problem of incorrect test case changes due to different parameter settings of different manufacturers, thus improving the accuracy of BMS controller HIL test.
