[0002] New energy vehicles (NEVs) differ significantly from traditional vehicles in their construction. This has led to significant changes in the scope and implementation of their thermal management systems, placing higher demands on the energy efficiency and safety of their components. The main functions of a NEV battery thermal management system include: When the battery temperature is too high, the system must rapidly dissipate heat to prevent thermal runaway accidents; in low-temperature environments, the system must preheat the battery to raise its temperature, ensuring charging and discharging performance in low-temperature conditions and preventing performance degradation due to low temperatures; and by reducing temperature differences within the battery pack, the formation of localized hot zones is suppressed, preventing rapid battery degradation caused by high-temperature areas, thereby extending the overall battery pack life. To achieve these functions, NEVs must integrate multiple heat dissipation components and pipelines to form an efficient thermal management module.

Specifically, the thermal management module refers to the system components used to control and regulate heat within the vehicle. The thermal management module ensures that all components within a new energy vehicle operate at optimal operating temperatures. The refrigerant-side unit 210 is the portion of the thermal management module responsible for handling refrigerant and primarily includes components such as the compressor 211, pressure and temperature sensor 212, electronic expansion valve 213, and solenoid valve 214.

[0055] Specifically, under-load operation refers to testing or operating the thermal management module while it is in its actual operating state, simulating the load conditions it would experience in a real application. In this state, the thermal management module must not only start up but also handle a specific workload to ensure its performance, efficiency, and reliability. During under-load operation, the module's operating status can be monitored in real time, capturing relevant data to determine its compliance.

[0056] In an embodiment of the present invention, the load operation of the thermal management module can simulate the working state of the thermal management module under actual working conditions, thereby testing the actual performance and response capability of the thermal management module to ensure its normal operation under load conditions.

[0066] S330 , controlling the tooling board to be tested provided with the thermal management module to enter the testing station and connect to the functional testing platform.

[0067] In an embodiment of the present invention, the tooling board to be tested is moved to a preset testing position to ensure that the thermal management module is correctly docked with the functional testing platform, so as to prepare for subsequent functional testing.

[0068] Optionally, control the tooling board to be inspected, which is equipped with a thermal management module, to enter the inspection station; determine whether the tooling board to be inspected is in a preset position; if the tooling board to be inspected is in the preset position, connect the tooling board to be inspected to the functional inspection platform through an automatic docking plug.

[0069] Specifically, an automatic docking plug refers to a connection device that is generally used to achieve fast, automated docking of electrical or signal connections.

[0070] In this embodiment of the present invention, an automatic docking plug automatically identifies and docks with the interface of the functional testing station after the tooling board to be tested has been moved to a preset position, ensuring a reliable and stable electrical connection. This design not only improves connection efficiency but also reduces the possibility of manual operation and the risk of connection errors, thereby ensuring the accuracy and effectiveness of the thermal management module during testing.

[0072] Specifically, the operating instructions refer to a set of specific control signals or commands used to instruct the thermal management module to operate under load conditions. Exemplary operating instructions may include: startup instructions, load settings, parameter configuration, and monitoring instructions.

[0073] In the embodiment of the present invention, an operation instruction is sent to the thermal management module to start the thermal management module to run under load, thereby simulating its working state in actual use and evaluating its performance.

[0074] S350: Obtaining a pressure signal, a temperature signal, and a valve communication signal during the operation of the thermal management module; wherein the valve communication signal includes an opening signal of the electronic expansion valve and an opening signal of the solenoid valve.

[0075] Specifically, the pressure signal refers to the pressure level of the refrigerant inside the thermal management module or in the system. The temperature signal refers to the temperature information of the refrigerant in the agent-side circuit of the thermal management module.

The valve communication signal refers to the communication information sent by each component inside the thermal management module, which may include the valve opening signal of each valve, the operating status signal of the compressor, and the operating status signal of each component. For example, the valve communication signal includes the opening signal of the electronic expansion valve and the opening signal of the solenoid valve. Monitoring the operating parameters of the compressor and parameters such as the valve opening can comprehensively evaluate the effectiveness of the thermal management system.

[0076] S360: If the pressure signal is within the preset pressure range, the temperature signal is within the preset temperature range, and the valve communication signal is within the preset opening range, then determine that the thermal management module is qualified.

[0077] Specifically, during operation, the thermal management module must simultaneously meet the requirements that the pressure is within the preset pressure range of the design or safety specifications, the temperature is within the preset temperature range of the design or safety specifications, and the opening of each valve is within the preset temperature range of the design or safety specifications to ensure the performance stability and safety of the thermal management module under actual working conditions.

[0078] S370: If the pressure signal is not within the preset pressure range, the temperature signal is not within the preset temperature range, or the valve communication signal is not within the preset opening range, it is determined that the thermal management module is not a qualified component.

[0079] Specifically, during operation, if the pressure signal falls below or exceeds a preset range, the temperature falls below or exceeds a preset range, or the communication signal from any component of the thermal management module falls outside the preset opening range, the module is deemed unqualified. This judgment mechanism promptly identifies potential problems or failures, ensuring that unqualified modules are not released to the market or put into use. This approach reduces safety risks and improves overall product quality.

[0080] The technical solution of the embodiments of the present invention, by filling the agent-side unit with refrigerant to form an agent-side closed loop and achieve electrical connection to the thermal management module, controls the tooling board to be tested to enter the testing station and connect it to the functional testing station, performs a load operation test, obtains pressure signals, temperature signals, and communication signals, and directly evaluates the performance of the thermal management module. This invention solves the problem of low reliability and poor accuracy of test results caused by indirect detection in the prior art, and can improve detection accuracy and reliability.
