[0002] The increasing popularity and development of electric vehicles (EVs) has placed higher demands on battery packs and their management systems, particularly regarding performance and safety in extreme temperature conditions. Battery pack temperature directly impacts charging efficiency and battery life, making effective battery heating and cooling essential. In the real world of EVs, ensuring the effectiveness of on-the-go heating and cooling is crucial for enhancing the user experience and ensuring battery safety.

[0003] Traditional battery in-transit heating and cooling function testing methods rely on real-vehicle testing, which has multiple limitations. First, real-vehicle testing is expensive because it requires a real vehicle environment, including complex operating conditions such as specific temperature, humidity, and vehicle status. This not only increases testing costs but also extends the testing cycle. Second, real-vehicle testing has poor repeatability. Due to the influence of natural ambient temperature fluctuations, it is difficult to create and repeat extreme temperature conditions within the same season, which limits the comprehensiveness and flexibility of the test. Therefore, how to achieve efficient and flexible testing of vehicle in-transit heating and cooling functions is one of the important technical issues in the relevant technical field.

[0035] Figure 1 FIG. 1 is a flow chart of a vehicle battery function test method according to one embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0036] Step S101 : determining a test case based on vehicle test requirements, wherein the vehicle test requirements are determined based on a test object, and the test object includes one of the following: a battery heating function during vehicle driving, and a battery cooling function during vehicle driving.

[0037] First, the specific requirements of vehicle testing are clarified. These requirements are directly derived from the requirements and analysis of the on-the-go heating and cooling functions of the battery management system and vehicle controller during the product design phase.

[0038] In an optional embodiment, the test object is the battery heating function or the battery cooling function during vehicle driving, depending on the goal of the test phase.

[0039] Based on vehicle testing requirements, the process of determining test cases involves selecting or designing a series of representative test scenarios, including normal and abnormal operating conditions, to comprehensively evaluate the performance of the battery management system and vehicle controller.

[0040] Step S102 : According to the test case, the simulation software is controlled to perform operating condition simulation to obtain operating condition simulation data, wherein the operating condition simulation data is used to characterize the operating conditions required for the vehicle battery function test.

[0041] After determining the test cases, professional simulation software is used to simulate the vehicle operating conditions according to the designed test cases and generate operating condition simulation data. This data will be used to simulate various environmental conditions in actual vehicle operation, such as battery temperature, vehicle speed, and ambient temperature, in order to test whether the battery management system and vehicle controller can respond correctly under these conditions.

[0042] Step S103: triggering the battery management system to generate a test request signal according to the operating condition simulation data.

[0043] When the hardware resources on the hardware-in-the-loop simulation platform receive the operating condition simulation data, they will send corresponding signals to the Battery Management System (BMS), such as signals indicating that the battery temperature is too low or too high, to trigger the BMS to generate a test request signal.

[0044] It should be noted that the BMS will determine whether it is necessary to start the battery heating or cooling function based on the received signal, and generate a corresponding request signal to ensure that the battery is in the best working condition.

[0045] Step S104: triggering the vehicle controller to generate a test permission signal according to the working condition simulation data and the test request signal.

[0046] Once the BMS generates a test request signal, it is passed to the Vehicle Control Unit (VCU). Based on the received operating condition simulation data and the BMS test request signal, the VCU determines whether to enable the heating or cooling function. It then generates a test enable signal and feeds it back to the BMS, forming a closed-loop control process. This process verifies the VCU's ability to correctly understand and respond to BMS requests.

[0047] Step S105 , performing a vehicle battery function test on the test request signal and the test permission signal to obtain a test result, wherein the test result is used to reflect the effectiveness of the vehicle battery function.

[0048] The generated test request signal and test permission signal are tested to determine whether the current vehicle battery function is valid.

[0049] In an embodiment of the present invention, a test case is determined according to a vehicle test requirement, wherein the vehicle test requirement is determined based on a test object, and the test object includes one of the following: a battery heating function during vehicle driving, and a battery cooling function during vehicle driving; according to the test case, the simulation software is controlled to perform operating condition simulation to obtain operating condition simulation data, wherein the operating condition simulation data is used to characterize the operating conditions required for the vehicle battery function test; according to the operating condition simulation data, the battery management system is triggered to generate a test request signal; according to the operating condition simulation data and the test request signal, the vehicle controller is triggered to generate a test permission signal; the vehicle battery function test is performed on the test request signal and the test permission signal to obtain a test result, wherein the test result is used to reflect the effectiveness of the vehicle battery function. The present invention uses simulation software to simulate operating conditions, replacing actual vehicle testing, greatly reducing testing costs. Precise control of operating condition simulation data enables testing to be performed quickly and repeatedly in a virtual environment, improving testing efficiency and shortening the time of the entire testing process. At the same time, the simulation software can simulate all operating conditions required for the vehicle's on-the-go battery heating and cooling functions, which overcomes the problem of environmental condition limitations in actual vehicle testing and allows testing to be performed at any time and any place, improving the flexibility and comprehensiveness of the test, and achieving efficient and flexible testing of the vehicle's on-the-go heating and cooling functions, thereby solving the technical problem of how to achieve efficient and flexible testing of the vehicle's on-the-go heating and cooling functions.

[0050] Optionally, triggering the battery management system to generate a test request signal based on the operating condition simulation data includes the following steps:

[0051] Step S1031, using hardware test bench resources to perform signal simulation processing on the working condition simulation data to obtain a test simulation signal;

[0052] Optionally, within the hardware-in-the-loop (HIL) simulation testing framework, hardware test bench resources refer to a series of hardware devices capable of simulating the actual operating conditions of a vehicle, including but not limited to power simulators, signal generators, temperature sensors, and current simulators. These resources simulate signals such as battery pack temperature, vehicle charging status, and thermal management system status based on the operating condition simulation data generated by the simulation software, generating test simulation signals.

[0053] Step S1032: triggering the battery management system to generate a test request signal according to the test simulation signal.

[0054] After the BMS receives the operating condition signal (i.e., test simulation signal) simulated by the hardware test bench resources, it will make a judgment based on the preset algorithm and decision logic and generate a corresponding test request signal.

[0055] For example, if the received test simulation signal indicates that the battery temperature is below a preset threshold, the temperature control algorithm within the BMS determines whether the conditions for activating the heating function are met. If so, the BMS generates a test request signal, which instructs the vehicle controller to activate the heating function.

[0056] Optionally, triggering the vehicle controller to generate a test permission signal based on the operating condition simulation data and the test request signal includes the following steps:

[0057] Step S1041, using hardware test bench resources to perform signal simulation processing on the working condition simulation data to obtain a test simulation signal;

[0058] The hardware test bench resources simulate signals such as battery pack temperature, vehicle charging status, and thermal management system status based on the operating condition simulation data generated by the simulation software to form test simulation signals.

[0059] Step S1042: triggering the vehicle controller to generate a test permission signal according to the test simulation signal and the test request signal.

[0060] When the VCU receives the test request signal from the BMS and the test simulation signal simulated by the hardware test bench resources, it will execute its built-in logical judgment and decision-making algorithm based on the current vehicle status and the received signals.

[0061] If the current vehicle status and operating conditions meet the requirements for activating the battery heating or cooling function, the VCU generates a test permission signal, which is a signal sent to the BMS to confirm that the corresponding function can be activated. This process verifies that the VCU can respond appropriately when receiving the request signal.

[0062] Optionally, performing a vehicle battery function test on the test request signal and the test permission signal to obtain a test result includes: performing a vehicle battery function test on the test request signal and the test permission signal based on preset evaluation criteria to obtain a test result.

[0063] The preset evaluation criteria are predefined evaluation standards used to measure the correctness of the generated test request signal and test permission signal, thereby determining whether the battery's in-transit heating and cooling functions are effective.

[0064] Optionally, performing a vehicle battery function test on the test request signal and the test permission signal based on a preset evaluation criterion to obtain a test result includes the following steps:

[0065] Step S1051, in response to the test request signal and the test permission signal being consistent with the expected result preset in the preset evaluation criteria, determining the test result as a test pass;

[0066] The test request signal and test permission signal actually generated during the test are compared with the expected results defined in the preset evaluation criteria to determine whether they are consistent.

[0067] The expected results are pre-defined based on the working condition simulation data and are used to characterize the test request signal and test permission signal that should be generated under ideal circumstances.

[0068] If the test request signal generated by the BMS and the test permission signal responded by the VCU are completely consistent with expectations, the test system will determine the test result as "test passed", which means that the battery in-transit heating or cooling function works normally as expected under the current test environment.

[0069] Step S1052 , in response to at least one of the test request signal and the test permission signal being inconsistent with an expected result preset in a preset evaluation criterion, determining that the test result is a test abnormality.

[0070] If during the test process, whether it is the test request signal sent by the BMS or the test permission signal responded by the VCU, as long as any signal does not match the expected result defined in the preset evaluation criteria, the test system will determine the test result as "test abnormality".

[0071] Optionally, the vehicle battery function testing method further includes the following steps:

[0072] Step S1061, in response to the test result being a test abnormality, obtaining test abnormality information;

[0073] When a test result is determined to be "test abnormal," relevant test abnormality information is automatically collected, including but not limited to vehicle status data at the time of the abnormality, signal interaction records between the BMS and VCU, etc. This information provides basic data for subsequent abnormality cause analysis.

[0074] Step S1062, determining the cause of the test abnormality based on the test abnormality information;

[0075] Based on the collected test anomaly information, conduct an in-depth analysis of the root cause of the anomaly. This involves reviewing software algorithms, checking hardware performance, or troubleshooting at the system integration level. For example, if the generated test request signal is abnormal, check the temperature control logic in the BMS; if the generated test enable signal does not meet expectations, focus on the temperature control logic in the VCU.

[0076] Step S1063: trigger the exception handling process according to the test exception cause and the preset exception handling mechanism.

[0077] After determining the cause of the test exception, the corresponding exception handling process is initiated according to the preset exception handling mechanism. The exception handling mechanism usually includes the repair strategy for different types of exceptions, the assignment of responsibilities, the prioritization, and the subsequent testing arrangements.

[0078] For example, if the cause of the anomaly is due to improper temperature control logic in the BMS, the software development team may need to re-optimize the algorithm logic; if the anomaly is attributed to insufficient hardware performance, the hardware design team may need to upgrade or replace related components.

[0079] The triggering of the exception handling process ensures that problems can be identified and effectively resolved in a timely manner, avoiding abnormal problems from causing greater impact in subsequent development or mass production stages.

[0080] Optionally, the test case includes a first test case. Determining the test case according to vehicle test requirements includes the following steps:

[0081] Step S1071: In response to the current test object being the battery heating function during vehicle driving, a first test scenario is determined based on vehicle testing requirements, wherein the first test scenario includes at least one of the following: an instant battery heating scenario in a low-temperature environment, and a battery heating scenario in a low-temperature environment based on fault injection;

[0082] When it is determined that the current test object is to verify the battery heating function of the vehicle during driving, a first test scenario most relevant to the battery heating function is selected according to vehicle testing requirements.

[0083] In an optional embodiment, the first test scenario includes an immediate battery heating scenario in a low-temperature environment and a battery heating scenario in a low-temperature environment based on fault injection. The immediate battery heating scenario in a low-temperature environment focuses on testing whether the function can be started correctly, while the battery heating scenario in a low-temperature environment based on fault injection is intended to verify the robustness and fault handling capabilities of the function.

[0084] The instant battery heating scenario in a low-temperature environment is used to simulate whether the battery heating function can be effectively started and the battery pack temperature can be effectively increased when the vehicle is driving in a cold environment.

[0085] The battery heating scenario in a low-temperature environment based on fault injection is used to simulate a low-temperature environment while artificially injecting certain fault signals (such as battery pack short circuit, heating element failure, etc.) to test the performance of the battery heating function under fault conditions.

[0086] Step S1072: Determine a first test case according to the first test scenario.

[0087] After determining the first test scenario, a specific first test case is designed based on the characteristics and functional requirements of that scenario. The test case should cover key parameters of the scenario, such as the ambient temperature range, initial battery temperature, fault type, and fault injection timing. By precisely setting these parameters, the test case can comprehensively verify the performance of the battery heating function in a specific scenario and the response strategy when faced with a fault.

[0088] Optionally, the test case includes a second test case. Determining the test case according to vehicle test requirements includes the following steps:

[0089] Step S1081: In response to the current test object being the battery cooling function during vehicle driving, a second test scenario is determined based on vehicle testing requirements, wherein the second test scenario includes at least one of the following: an immediate battery cooling scenario in a high temperature environment, and a battery heating scenario in a high temperature environment based on fault injection;

[0090] When the current test object is the battery cooling function during vehicle driving, a second test scenario suitable for cooling function testing is determined based on the actual needs of the vehicle driving in a high temperature environment.

[0091] In an optional embodiment, the second test scenario includes an immediate cooling scenario in a high temperature environment and a battery cooling scenario in a high temperature environment based on fault injection.

[0092] The instant battery cooling scenario in a high-temperature environment is used to simulate whether the cooling function can be effectively activated and effectively reduce the battery temperature when the vehicle is driving in a hot environment (such as a temperature above 40°C).

[0093] The battery cooling scenario in a high-temperature environment based on fault injection is used to simulate a high-temperature environment while artificially injecting specific faults (such as coolant leakage, fan failure, etc.) to evaluate the processing logic of the battery cooling function under fault conditions.

[0094] Step S1082: Determine a second test case according to the second test scenario.

[0095] Based on the second test scenario, design specific second test cases to refine the test execution parameters and conditions. The construction of the second test case should cover the key elements of the scenario, such as the high temperature environment setting, vehicle driving status, fault type, and injection timing.

[0096] In an optional embodiment, Figure 2 FIG. 1 is a block diagram of an automated test device for hardware-in-the-loop simulation of vehicle heating and cooling functions in transit according to one embodiment of the present invention. Figure 2As shown, the device includes: a host computer system 10, a real-time simulation system (i.e., a hardware-in-the-loop simulation platform) 20, a BMS controller 30, and a vehicle controller 40. By manipulating the software in the host computer system 10, the simulation model in the host computer in the hardware-in-the-loop simulation platform sends a corresponding signal to the simulation board, which then sends the signal to the BMS controller 30 and the vehicle controller 40. The in-transit heating and cooling related signals fed back by the BMS and the vehicle controller are collected and transmitted to the host computer to check the test results. The host computer system 10 is connected to the HIL simulation platform (Hardware-in-the-Loop, Hardware-in-the-Loop simulation platform) 20 via Ethernet; the HIL simulation platform 20 is connected to the BMS controller 30 under test via a CAN line and a hard line, and the HIL simulation platform 20 is connected to the vehicle controller 40 via a CAN line, a hard line, and an on-board Ethernet line.

[0107] In an optional embodiment, Figure 6 FIG. 1 is a flow chart of a method for simulating a vehicle battery on-the-go heating and cooling function test according to one embodiment of the present invention. Figure 6 As shown, the method is specifically implemented as follows:

The test instructions should include signals such as battery pack temperature, pressure, voltage, vehicle insulation fault level, host navigation status, navigation location, and battery pack remaining power.

[0111] Step S540, the battery management system BMS generates a battery in-transit heating or cooling request based on the received interaction signal;

[0112] Step S550, the vehicle controller generates a battery in-transit heating or cooling permission signal based on the received interaction signal;

[0113] Step S560: Based on the instructions sent by the BMS controller and the in-transit heating or cooling permission signal sent by the vehicle controller, combined with preset evaluation criteria, determine whether the in-transit heating or cooling function logic of the BMS controller and the vehicle controller is normal, and automatically generate a test report;

[0114] Step S570: Analyze the test problems based on the automated test report and upload them to the server test management system. At the same time, notify the person in charge of the in-transit heating or cooling function to rectify and track the problems.

[0115] In summary, the present invention provides a hardware-in-the-loop (HIL) simulation automated testing device and method for the on-the-go heating and cooling functions of electric vehicle battery packs. By building a HIL simulation system, the battery management system and vehicle controller of the electric vehicle are used as the controllers under test to simulate the operating conditions required for the BMS's on-the-go heating and cooling functions, such as the battery pack temperature, vehicle navigation distance, remaining vehicle mileage, and thermal management system operating status, to test whether its on-the-go heating or cooling functions are functioning properly. By using the HIL simulation system for simulation testing, design errors in the battery's on-the-go heating or cooling functions can be discovered earlier in the development process, reducing the cost of error repair. Using a simulation board to simulate the battery pack temperature solves the problem of being unable to create extreme operating conditions in real vehicle testing, as well as the difficulty and poor repeatability of creating real vehicle testing conditions. It also solves the problems of low test efficiency, long test cycles, incomplete coverage, and proneness to errors. At the same time, by using the simulation test equipment to create reverse operating conditions such as various faults, the robustness of the software can be guaranteed. The introduced automated testing system shortens testing time and improves testing efficiency. At the end of the test, a test report is automatically generated and test issues are uploaded to the test problem management system. In addition, the present invention enables the test scenarios to be supplemented at any time, thereby increasing the test coverage and functional test depth.
