In order to ensure the stable operation and long-term reliability of the motor and controller, an effective cooling system, especially a water cooling system, must be used to effectively manage this heat. However, during the operation of new energy vehicles, the cooling system needs to withstand repeated pressure changes.

[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] The main solution of the embodiment of the present application is: obtaining the pressure holding time, pressure release time and pulse number of the pressure pulse test task, and configuring the first control time of the cycle delay relay based on the pressure holding time, configuring the second control time of the cycle delay relay based on the pressure release time, and configuring the control number of the counting relay based on the pulse number; controlling the water inlet solenoid valve to be continuously opened and the return water solenoid valve to be continuously closed for the first control time by the cycle delay relay, so as to inject water and pressurize the pipeline to be tested through the water inlet module connected to the water inlet solenoid valve; after reaching the first control time, controlling the water inlet solenoid valve to be continuously closed and the return water solenoid valve to be continuously opened for the second control time by the cycle delay relay, so as to release the pressure applied to the pipeline to be tested, and returning to execute the step of controlling the water inlet solenoid valve to be continuously opened and the return water solenoid valve to be continuously closed for the first control time by the cycle delay relay; accumulating the return execution times of the cycle delay relay through the counting relay, and stopping the execution of the pressure pulse test task after the return execution times reach the control times.

[0047] During the operation of new energy vehicles, the cooling system needs to withstand repeated pressure changes. These changes may come from vibrations during vehicle driving, temperature changes, or pressure fluctuations within the system. Long-term pressure changes may cause fatigue or damage to cooling system components. At the same time, during the design and manufacturing process of the cooling system, there may be unreasonable designs or manufacturing defects, such as sand holes and seal failures. These defects may not be easy to detect under normal operating conditions. Therefore, how to effectively detect the reliability and durability of the cooling system is a problem that needs to be solved urgently.

[0048] The present application provides a solution, which controls the periodic opening and closing of the water inlet solenoid valve and the water return solenoid valve through the use of a programmed controlled cycle delay relay and a counting relay, so as to perform periodic pulse testing on the pipeline to be tested, thereby avoiding the problems of inconsistency of test parameters and operating errors caused by manual control, ensuring the accurate execution of the pressure holding time, pressure relief time and number of pulses during the test, improving the reliability and repeatability of the test, and thus achieving the effect of accurate and repeated pressure pulse testing of the cooling system.

[0049] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device that can realize the above functions. The following takes an electronic device as an example to illustrate this embodiment and the following embodiments.

[0050] Based on this, the present application embodiment provides a pressure pulse test method, referring to Figure 1 , Figure 1This is a flow chart of the first embodiment of the pressure pulse testing method of the present application.

[0051] In this embodiment, the pressure pulse test method is applied to a pressure pulse test system, which includes a water inlet, a water return port, a pipeline to be tested connected between the water inlet and the water return port, a water inlet solenoid valve arranged on the water inlet, a water return solenoid valve arranged on the water return port, a circulation delay relay respectively connected to the water inlet solenoid valve and the water return solenoid valve, a counting relay respectively connected to the water inlet solenoid valve, the water return solenoid valve and the circulation delay relay, and a main control module respectively connected to the circulation delay relay and the counting relay. The pressure pulse test method includes using the main control module to perform the following steps S10 to S40:

[0052] Step S10, obtaining the pressure holding time, pressure release time and pulse number of the pressure pulse test task, and configuring the first control time of the cycle delay relay based on the pressure holding time, configuring the second control time of the cycle delay relay based on the pressure release time, and configuring the control number of the counting relay based on the pulse number;

[0053] It should be noted that the pressure holding time refers to the length of time that the pressure is maintained on the pipeline to be tested after the pressure is applied to the pipeline to be tested; the pressure release time refers to the length of time that the pressure applied to the pipeline to be tested is released to the preset minimum threshold after the pressure holding time ends; the number of pulses refers to the number of cycles of applying and releasing pressure to the pipeline to be tested during the entire pressure pulse test process.

[0054] In addition, it should be noted that the first control time length configured by the cyclic delay relay is equal to the pressure holding time length, the second control time length is equal to the pressure release time length, and the control times configured by the counting relay is equal to the pulse times.

[0055] It is understandable that since the pipeline to be tested needs to remain stable under a certain pressure and also needs to get appropriate material rest time, step S10 is performed. By configuring the cycle delay relay based on the pressure holding time and pressure release time of the pressure pulse test task, and configuring the counting relay based on the pulse number of the pressure pulse test task, it is possible to avoid the inability to accurately evaluate the performance of the components to be pressed due to the uncontrollable pressure maintenance time, and the impact damage caused by the uncontrollable pressure release. The problems can be avoided, thereby realizing the durability and reliability of the pipeline to be tested under any pressure, and also realizing the safety detection of the pipeline to be tested in the pressure cycle. In addition, by setting the number of pulses to simulate the repeated pressure changes that the cooling system is subjected to during actual operation, so as to evaluate the long-term durability of the pipeline to be tested, it is possible to avoid the inability to fully evaluate the fatigue life of the pipeline to be tested due to insufficient test times, thereby realizing the performance evaluation of the pipeline to be tested under multiple pressure cycles. In summary, specific test parameters are set according to the test requirements to ensure that the test process meets the expected pressure cycle mode, avoiding problems such as inaccurate test results or uncontrollable test process due to improper parameter settings, and achieving accurate and repeatable pressure pulse testing on the pipeline to be tested, ensuring the reliability and effectiveness of the test results.

[0056] Exemplarily, the main control module first reads the preset pressure holding time, pressure release time and pulse number from the test task parameter library or the user input interface. Then, the main control module adjusts the delay time (including the first control time and the second control time) of the cycle delay relay according to these parameters to ensure that the relay can accurately switch the state of the solenoid valve during the pressure holding and pressure release stages. At the same time, the main control module sets the counting upper limit (i.e., the control number) of the counting relay according to the number of pulses, so as to stop the test after reaching the specified number of times.

[0057] Step S20, controlling the water inlet solenoid valve to be continuously opened and the water return solenoid valve to be continuously closed for the first control time through the cycle delay relay, so as to inject water and pressurize the pipeline to be tested through the water inlet module connected to the water inlet solenoid valve;

[0058] It should be noted that the water inlet module refers to a device used to apply pressure to the pipeline to be tested, which may include components such as a high-pressure water tank and a water pump; the pipeline to be tested includes but is not limited to the pipelines in the cooling system of new energy motors and controllers.

[0059] It can be understood that since it is necessary to simulate the pressure changes that the cooling system is subjected to in actual work in order to detect the pressure resistance performance of the pipeline to be tested, step S20 is performed to avoid problems such as component damage or poor test results caused by improper pressure control, thereby realizing performance testing of the pipeline to be tested under simulated working pressure and ensuring the stability and safety of the pipeline to be tested in actual use.

[0060] For example, when starting the test, the cycle delay relay activates the water inlet solenoid valve to keep it open, while ensuring that the return water solenoid valve is closed, so that the water inlet module can continuously supply water to the pipeline to be tested, thereby applying a certain pressure to the pipeline to be tested. This process will continue for a specified pressure holding time (i.e., the first control time) to ensure that the pipeline to be tested is under sufficient pressure for performance evaluation.

[0061] Step S30, after reaching the first control time, controlling the water inlet solenoid valve to be continuously closed and the water return solenoid valve to be continuously opened for the second control time by the cycle delay relay to release the pressure applied to the pipeline to be tested, and returning to the step of controlling the water inlet solenoid valve to be continuously opened and the water return solenoid valve to be continuously closed for the first control time by the cycle delay relay;

[0062] It is understandable that since it is necessary to allow the pipeline to be tested to have a pressure release process in the continuous pressure pulse test to simulate the pressure cycle in actual work, step S30 is performed to avoid fatigue damage to components caused by continuous high pressure or distortion of test results due to insufficient pressure relief, thereby realizing fatigue life assessment of the pipeline to be tested in the pressure cycle, thereby ensuring the long-term operation reliability of the pipeline to be tested.

[0063] For example, when the first control time for maintaining pressure is reached, the cycle delay relay will close the water inlet solenoid valve and open the water return solenoid valve at the same time, allowing the water in the pipeline to be tested to flow back, thereby quickly reducing the pressure inside the component. This process will continue for the specified pressure relief time (i.e., the second control time) to ensure that the pressure in the pipeline to be tested is completely released and prepare for the next pressure pulse cycle.

[0064] Step S40, accumulating the return execution times of the cyclic delay relay through the counting relay, and stopping the execution of the pressure pulse test task after the return execution times reaches the control times.

[0065] It should be noted that the number of return executions refers to the number of pressure pulse cycles that have been completed during the entire pressure pulse test process.

[0066] It is understandable that since it is necessary to ensure that the test is completed according to the preset number of times to ensure the consistency and completeness of the test, performing step S40 can avoid the problem of insufficient or excessive test times due to counting errors, thereby affecting the accuracy of the test results, thereby achieving accurate cyclic pressure testing of the pipeline to be tested, ensuring the controllability of the test process and the accuracy of the test results.

[0067] For example, each time a pressure pulse cycle is completed, the counting relay will automatically accumulate the number of executions. When the accumulated number of executions reaches the preset number of pulses, i.e., the control number, the counting relay will trigger the stop mechanism of the test system, close the water inlet solenoid valve, open the water return solenoid valve, and end the pressure pulse test task. This ensures that the test is completed accurately according to the predetermined number of times, and does not cause component damage due to excessive testing or affect the evaluation results due to insufficient testing.

[0068] The present embodiment provides a pressure pulse testing method, which uses a programmed controlled cycle delay relay and a counting relay to control the periodic opening and closing of the water inlet solenoid valve and the water return solenoid valve to perform periodic pulse testing on the pipeline to be tested, thereby avoiding the problems of test parameter inconsistency and operating errors caused by manual control, ensuring the accurate execution of the pressure holding time, pressure release time and pulse number during the test, improving the reliability and repeatability of the test, and achieving the effect of accurate and repeatable pressure pulse testing of the cooling system.

[0069] In a feasible implementation manner, the pressure pulse test system further includes a pressure sensor and an overpressure relief valve, wherein the pressure sensor is used to measure the pressure in the pipeline to be tested, and the pressure pulse test method further includes steps S01 to S02:

[0070] Step S01, monitoring the pressure data of the pressure sensor, and controlling the overpressure relief valve to open when the pressure data is greater than a preset pressure threshold;

[0071] It should be noted that pressure data refers to the pressure value in the test water channel where the pipeline to be tested is located, which is detected in real time by a pressure sensor. This data is usually expressed in physical units (such as Pascal, etc.) and is a key parameter for measuring the pressure state of the system.

[0072] It is understandable that since the pressure in the pipeline to be tested may be too high during the pressure pulse test, step S01 is performed. By setting up a pressure sensor and an overpressure relief valve, the overpressure relief valve is used to relieve the pressure in the pipeline to be tested when the pressure is too high. This can avoid safety accidents or equipment damage caused by pressure exceeding the bearing capacity of components or the bearing capacity of the test system. By releasing excess pressure in time, it is ensured that the test process can be carried out within a safe pressure range.

[0073] Exemplarily, the pressure sensor is installed at a key position of the pipeline to be tested, such as the water inlet and outlet of the pipeline to be tested, so as to collect the pressure data in the pipeline to be tested in real time. Then, the output signal of the pressure sensor is continuously read by the main control module, and the output signal is converted into a readable pressure value. When the main control module detects that the pressure value exceeds the preset safety threshold (i.e., the preset pressure threshold), the control circuit is immediately activated and a command is sent to the driving device of the overpressure relief valve, so that the overpressure relief valve is quickly opened, thereby releasing excess pressure and preventing the system from being over-pressurized.

[0074] Step S02: When the overpressure relief valve is open and the pressure data is less than or equal to the preset pressure threshold, control the overpressure relief valve to be closed.

[0075] It is understandable that since the overpressure relief valve being open for a long time will cause the system pressure to be too low or resources to be wasted, performing step S02 can avoid problems such as system performance degradation and component function damage caused by excessive pressure relief, thereby achieving the effect of precise pressure control, ensuring the stable operation of the system, and optimizing the full utilization of energy and resources.

[0076] For example, after the overpressure relief valve is opened and the system pressure is successfully reduced, the main control module continues to monitor the output of the pressure sensor. Once the pressure value is detected to be reduced to or equal to the preset safety threshold (i.e., the preset pressure threshold), the main control module will again send a command through the control circuit to close the drive device of the overpressure relief valve, thereby stopping the pressure relief process. This operation ensures that the system pressure will not be too low, while avoiding the unnecessary long-term opening of the pressure relief valve, ensuring the normal operation of the system and the effective use of energy.

[0077] In this embodiment, by using a pressure sensor to monitor and feedback control the overpressure relief valve, when the monitored pressure data is greater than the preset pressure threshold, the overpressure relief valve is opened in time to release excess pressure and prevent system overpressure; when the pressure data drops to or below the preset threshold, the overpressure relief valve is closed to keep the system within the normal working pressure range, thereby ensuring the stable operation and safety of the system, while avoiding low system pressure or waste of resources due to long-term opening of the pressure relief valve, realizing real-time monitoring and precise control of system pressure, and achieving the purpose of optimizing system performance and protecting equipment.

[0078] In a feasible implementation manner, the pressure pulse test system further includes an emergency stop button and a power module, wherein the power module is used to supply power to the water inlet solenoid valve, the water return solenoid valve, the cycle delay relay and the counting relay, and the pressure pulse test method further includes step S100:

[0079] Step S100, cutting off the power supply from the power module to the water inlet solenoid valve, the water return solenoid valve, the cycle delay relay and the counting relay through the emergency stop button to stop executing the pressure pulse test task.

[0080] It is understandable that since emergencies or abnormalities may occur during the test, the test needs to be stopped immediately to ensure the safety of personnel or the integrity of equipment, so step S100 is performed. By adopting the emergency stop button as a means of emergency power cut-off, safety accidents or equipment damage caused by failure to stop the test in time are avoided, and the effect of quickly stopping the pressure pulse test task in an emergency is achieved, ensuring the safety of operators and equipment, preventing the occurrence of potential dangerous situations, and also providing guarantees for subsequent safety inspections and troubleshooting.

[0081] Exemplarily, an emergency stop button is provided in the pressure test system, and the button is directly connected to the output end of the power module through an electrical connection. When the operator recognizes an emergency or abnormality during the test, the emergency stop button can be quickly pressed. After pressing the emergency stop button, a mechanical or electronic switch will be triggered, which will immediately cut off the output of the power module, thereby disconnecting the circuit that supplies power to the water inlet solenoid valve, the water return solenoid valve, the cycle delay relay, and the counting relay. This operation will cause all these electrical components to lose power instantly, the water inlet solenoid valve and the water return solenoid valve will stop working, and the cycle delay relay and the counting relay will also stop performing their delay and counting functions. The entire pressure pulse test task is therefore stopped immediately, thereby ensuring the safe shutdown of the test system.

[0082] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 The pressure pulse test system further includes a power module, a switch button, an air intake solenoid valve, and an intermediate relay connected to the water return solenoid valve, wherein the power module is used to supply power to the water intake solenoid valve, the water return solenoid valve, the cycle delay relay and the counting relay. After step S40, the pressure pulse test method further includes steps S50 to S60:

[0083] Step S50, cutting off the power supply from the power module to the water inlet solenoid valve, the cycle delay relay and the counting relay through the switching button;

[0084] It can be understood that since it is necessary to safely stop the power supply to the relevant electrical components after the test is completed or when the system maintenance is performed, performing step S50 can avoid safety accidents or equipment damage caused by accidental startup of electrical components, thereby safely controlling the start and stop of the test system and improving the operational safety of the system.

[0085] For example, a switch button is installed in the test system, and the button is connected to the output end of the power module through a circuit. After the pressure pulse test task is completed, the button can be automatically triggered by the main control module, or manually triggered by the operator, thereby closing or disconnecting the circuit, cutting off the power supply from the power module to the water inlet solenoid valve, the cycle delay relay and the counting relay, and switching the power module to supply power to the air inlet solenoid valve. This operation ensures that these electrical components stop working immediately, avoiding any potential electrical hazards.

[0086] Step S60, controlling the intermediate relay to keep the water return solenoid valve open, and controlling the air intake solenoid valve to be continuously open, so as to clean the pipeline to be tested through a preset air source, wherein the preset air source is connected to the air intake solenoid valve.

[0087] It should be noted that the preset gas source refers to compressed air or other gas source that provides cleaning and driving functions for the test system. The gas source is connected to the air inlet solenoid valve through a pipeline and can adjust the pressure and flow as needed.

[0088] It is understandable that after the test task is completed, the liquid (such as coolant, etc.) remaining in the pipeline to be tested will cause certain damage to the hardware of the test system or have a certain impact on the next test task, so step S60 is performed to clear the residues in the test water channel by setting the air intake solenoid valve, thereby avoiding unnecessary impact on the hardware equipment and even the next test task caused by the residues after the test, thereby achieving effective cleaning of the test water channel, ensuring the accuracy and reliability of the next test, and extending the service life of the system components.

[0089] Exemplarily, first, a signal is sent to the intermediate relay based on the control circuit through the main control module, so that the intermediate relay is energized, thereby maintaining the open state of the return water solenoid valve. At the same time, another control signal is sent by the main control module to the air intake solenoid valve, so that the air intake solenoid valve is continuously opened to allow a preset air source (such as compressed air) to enter the pipeline to be tested through the air intake solenoid valve. The preset air source is connected to the air intake solenoid valve through a pipeline. When the air source is activated, high-pressure gas will flow through the pipeline to be tested between the water intake solenoid valve and the return water solenoid valve, thereby purging and cleaning the residue in the pipeline to ensure the cleanliness and smoothness of the pipeline.

[0090] In this embodiment, by adopting electrical control and pneumatic cleaning methods, safety accidents caused by accidental startup of electrical components and inaccurate testing or equipment damage caused by pipeline residues are avoided. The power supply of electrical components can be safely stopped after the test is completed, and the tested pipeline can be effectively cleaned, thereby ensuring the operational safety of the system and the accuracy of the test, while extending the service life of system components, thereby achieving the effect of optimizing system maintenance and ensuring test reliability.

[0091] For example, in order to help understand the actual application effect of the pressure pulse test method of the present application, the water-cooled plate pressure alternation test (i.e., pressure pulse test task) is configured according to the following table:

[0092]

[0093] Table 1

[0094] The pressure holding time shown in Table 1 is 3 to 5 seconds, the pressure release time can be 1 second, and the number of pulses is 200,000 times. In the initial inspection stage of the water-cooled plate pressure alternation test, first open the water inlet solenoid valve and the water outlet solenoid valve, and let the coolant (water and ethylene glycol solution) in the high-pressure water tank circulate in the pressure pulse test system for a period of time to remove the air in the system pipes, and confirm that all components of the system are tightly connected without leakage and are in normal working condition. In the formal testing stage, start the high-pressure water tank, set the pressure pulse time (including pressure holding time, pressure release time, and number of pulses), and start applying periodic pressure fluctuations. You can refer to Figure 4 As shown in the figure, the pressure holding time is 3s, the pressure release time is 1s, and the opening and closing states of the water inlet solenoid valve and the water outlet solenoid valve are opposite. During the formal test, the system main control module or the operator continuously monitors various indicators. If there is an obvious leak or other fault, the emergency stop button is immediately triggered to stop the test. After 200,000 pressure pulses, no obvious leakage was found in the pipeline to be tested (water cooling plate), and the pressure pulse test verification of the pipeline to be tested was determined to be qualified.
