[0003] The traditional waterproof testing process of energy storage exhaust valves is often static, only testing the waterproof performance of the energy storage exhaust valve under a fixed pressure, and unable to truly reflect the dynamic pressure changes (such as during the pressurization, pressure holding, and depressurization cycles) of the energy storage exhaust valve during actual operation, thereby resulting in inaccurate test results. Summary of the Invention

[0004] The embodiments of this application provide a waterproof testing method for energy storage exhaust valves and a fully automatic water spraying test device, which can solve the problem that the traditional waterproof testing process of energy storage exhaust valves is often static, only testing the waterproof performance of the energy storage exhaust valve under a fixed pressure, and unable to truly reflect the dynamic pressure changes of the energy storage exhaust valve during actual operation, thereby resulting in inaccurate test results.

[0005] In a first aspect, the embodiments of this application provide a waterproof testing method for energy storage exhaust valves, including:

[0006] Obtaining pressure information within a target time period; wherein, the pressure information is used to indicate the pressure change situation of the energy storage exhaust valve under test when bearing a fluid in a sealed state, and the sealed state is the state where the test device applies a predetermined sealing force to the exhaust valve;

[0007] Obtaining the number of change events; wherein, the number of change events is the number of water seepage detected when the test device performs a pressure loading action on the energy storage exhaust valve within the target time period; a complete pressure loading action includes a pressurization action, a pressure holding action, and a depressurization action;

[0012] The waterproof test method for the energy storage exhaust valve provided by this application, by obtaining the pressure change situation of the energy storage exhaust valve under test in a sealed state when bearing fluid during the target period, helps to understand the dynamic response of the valve when bearing fluid. By obtaining the number of water seepage detected during the pressure loading action on the energy storage exhaust valve by the test device within the target period, the leakage situation of the valve under different pressure conditions can be quantified, which helps to provide data support for subsequent determination of whether the waterproof performance of the energy storage exhaust valve meets the standard. By determining the number of cyclic tests of the pressure loading action on the energy storage exhaust valve by the test device within the target period, it helps to test the performance of the exhaust valve during multiple cycles, thereby reducing random errors, and thus helps to improve the accuracy of the test results.

Similarly, the phrase "if determined" or "if the described condition or event is detected" can be interpreted as meaning "once determined", "in response to determining", "once the described condition or event is detected", or "in response to detecting the described condition or event" according to the context.

[0060] In addition, in the description of the specification of the present application and the appended claims, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0061] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of this application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized.

[0062] In the related art, the energy storage exhaust valve is an important component applied in various industrial and automotive fields, mainly used to control the discharge of fluids and gases to ensure the normal operation and safety of the system.

[0063] The traditional waterproof test process of the energy storage exhaust valve is often static, only testing the waterproof performance of the energy storage exhaust valve under a fixed pressure, and unable to truly reflect the dynamic pressure changes (such as in the pressurization, pressure holding, and decompression cycles) of the energy storage exhaust valve during actual operation, thereby resulting in inaccurate test results.

[0064] To solve the above problems, the embodiments of this application provide a waterproof test method for an energy storage exhaust valve and a fully automatic water spraying test device.

[0065] In this method, by obtaining the pressure change situation of the energy storage exhaust valve under test in a sealed state when bearing fluids during a target time period, it helps to understand the dynamic response of the valve when bearing fluids. By obtaining the number of water seepage detected as effective water seepage during the pressure loading action of the test device on the energy storage exhaust valve during the target time period, the leakage situation of the valve under different pressure conditions can be quantified, which helps to provide data support for subsequent determination of whether the waterproof performance of the energy storage exhaust valve meets the standard. By determining the number of cyclic tests of the pressure loading action of the test device on the energy storage exhaust valve during the target time period, it helps to test the performance of the exhaust valve in multiple cycles, thereby reducing random errors, and thus helps to improve the accuracy of the test results. Thus, based on multiple factors such as the pressure change situation of the energy storage exhaust valve under test in a sealed state when bearing fluids during the target time period, the number of water seepage detected as effective water seepage during the pressure loading action of the test device on the energy storage exhaust valve during the target time period, and the number of cyclic tests of the pressure loading action of the test device on the energy storage exhaust valve during the target time period, it can be determined whether the waterproof performance of the energy storage exhaust valve under test meets the standard, avoiding misjudgment that may be caused by a single index (such as only relying on pressure), and making the determination of the waterproof performance more accurate and reliable.

[0066] The waterproof testing method for the energy storage exhaust valve provided by the embodiments of the present application can be applied to a full-automatic water spraying test device. At this time, the full-automatic water spraying test device is the execution subject of the waterproof testing method for the energy storage exhaust valve provided by the embodiments of the present application. The embodiments of the present application do not impose any restrictions on the specific type of the full-automatic water spraying test device.

[0067] For example, the full-automatic water spraying test device may include a pressure testing device, a testing device, and a control device. The control device is electrically connected to the pressure testing device and the testing device respectively. The energy storage exhaust valve can be installed on the pressure testing device (such as a gas compressor or a liquid pump, etc.) so that the pressure testing device applies a predetermined sealing force (torque, mechanical fastening force) to the energy storage exhaust valve to simulate the installation conditions in actual use. And the pressure testing device can deliver a fluid with a certain pressure to the energy storage exhaust valve to test the pressure change of the energy storage exhaust valve when bearing the fluid in the sealed state, and send the tested situation to the control device. The testing device (such as a waterproof performance tester, a water spraying testing machine, etc.) can be equipped with multiple adjustable nozzles, capable of simulating water spraying at different pressures to monitor the waterproof situation of the product under test (energy storage exhaust valve), such as water penetration, humidity, temperature, etc., and send the monitored information to the control device. The control device can determine whether the waterproof performance of the tested energy storage exhaust valve meets the standard according to the acquired pressure information and failure ratio.

[0068] For example, the control device can be a single-chip microcomputer, a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a desktop computer, a computing device or a computer connected to a wireless modem, a laptop computer, a handheld communication device, a handheld computing device, etc.

[0069] To better understand the waterproof testing method for the energy storage exhaust valve provided by the embodiments of the present application, the following provides an exemplary introduction to the specific implementation process of the waterproof testing method for the energy storage exhaust valve provided by the embodiments of the present application.

[0070] Figure 1 The schematic flowchart of the waterproof testing method for the energy storage exhaust valve provided by the embodiments of the present application is shown. The waterproof testing method for the energy storage exhaust valve includes:

[0071] S100, obtaining pressure information within a target period. Among them, the pressure information is used to indicate the pressure change of the energy storage exhaust valve under test when bearing the fluid in the sealed state, and the sealed state is the state where the pressure testing device applies a predetermined sealing force to the energy storage exhaust valve.

[0072] It can be understood that the target period can be 1 hour, 2 hours, 3 hours, etc. The pressure information can be the pressure change information caused by factors such as rapid changes in fluid, sharp changes in flow rate, start or stop of the pump, opening or closing of the valve, and defective sealing performance of the exhaust valve, such as slight wear of the sealing ring or impurities stuck on the sealing surface. The energy storage exhaust valve can be installed on the pressure test equipment so that the pressure test equipment applies a predetermined sealing force (torque, mechanical fastening force) to the energy storage exhaust valve to simulate the installation conditions in actual use, that is, to keep the energy storage exhaust valve in a sealed state.

[0073] Exemplarily, within the target period, the pressure change of the energy storage exhaust valve can be continuously monitored through a pressure sensor. The pressure information can be obtained through the sensor and recorded as a time-based continuous data stream.

[0074] With such a setting, by obtaining the pressure change of the energy storage exhaust valve under test in a sealed state when bearing fluid within the target period, it helps to understand the dynamic response of the valve when bearing fluid.

[0075] In a possible implementation, S100, obtaining the pressure information within the target period includes:

[0076] S110, recording the pressure maintenance period. Among them, the pressure maintenance period is the cumulative period during which the pressure of the energy storage exhaust valve in a sealed state within the target period remains stable within the target pressure range.

[0077] It can be understood that before starting the test, the target pressure range can be set. For example, if the target pressure range is 1 - 3 bar and the pressure change is less than the set threshold, the pressure must fluctuate between the two to be considered "stable". Within the target pressure range and when the pressure change (i.e., the maximum difference in pressure fluctuation) is less than the set threshold (such as ±4 bar), the time of each pressure maintenance can be recorded and this time period can be accumulated to obtain the pressure maintenance period.

[0078] Exemplarily, assume that the target pressure range is 5 - 10 bar, and the test system performs pressure loading and maintenance within 30 minutes: From the 1st to the 10th minute, the pressure stabilizes at 8 bar, meeting the target range. From the 11th to the 15th minute, the pressure fluctuates between 6 - 9 bar, and the pressure change is less than the set threshold (i.e., 9 bar - 6 bar is less than 4 bar), meeting the target range. From the 16th to the 25th minute, the pressure stabilizes at 7.5 bar again, meeting the target range. From the 26th to the 30th minute, the pressure fluctuates between 5 - 10 bar, and the pressure change is greater than the set threshold (i.e., 10 bar - 5 bar is greater than 4 bar), not meeting the target range. Then the cumulative pressure maintenance period: From the 1st to the 10th minute, it meets the condition, with a cumulative of 10 minutes. From the 16th to the 25th minute, it meets the condition, with a cumulative of 10 minutes. The total pressure maintenance period is 20 minutes.

[0079] Such a setting helps in subsequent evaluation of the waterproof performance of the energy storage exhaust valve.

[0080] In a possible implementation, S110, record the pressure maintenance period, including:

[0081] S111, during the test, determine whether the energy storage exhaust valve is in a sealed state.

[0082] It can be understood that a torque sensor can be used to obtain the torque and mechanical fastening force applied by the pressure test equipment to determine whether the energy storage exhaust valve is in a sealed state. If the obtained torque is the preset torque, it is determined that the energy storage exhaust valve is in a sealed state; otherwise, it is determined that the energy storage exhaust valve is not in a sealed state.

[0083] With such a setting, by setting a clear preset torque value, a quantitative standard can be provided, making the judgment process more objective and consistent, which helps to improve the repeatability and reliability of the test. It helps to reduce test misjudgments caused by improper torque application, thereby contributing to the accuracy of the test results.

[0084] S112, when it is determined that the energy storage exhaust valve is in a sealed state, calculate the pressure change rate based on the pressure data.

[0085] It can be understood that the pressure data of the energy storage exhaust valve can be continuously monitored through a pressure sensor. The pressure data can be obtained by the sensor and recorded as a time-based continuous data stream. During the pressure test, the recorded pressure data includes the pressure value (unit: bar) at each time point and the corresponding timestamp. And the pressure change rate can be the ratio of the pressure difference between two time points to the time difference between the two time points. For example, = , △P = P(t1) - P(t2), △t = t1 - t2.

[0086] With such settings, by continuously recording pressure data, the working state of the energy storage exhaust valve can be monitored in real time. If the pressure change rate is small and stable, it indicates normal. If the pressure change rate is abnormal, it may mean that there is a problem with the sealing of the energy storage exhaust valve. By calculating the change rate, problems such as leakage or pressure fluctuations can be quickly detected, providing data support for subsequent test results.

[0087] S113, if the pressure change rate is less than the preset threshold, record the start time and end time when the current pressure does not change.

[0088] It can be understood that a pressure change rate threshold is set, that is, the preset threshold. This preset threshold is used to judge whether the pressure change is less than the expected range. During the test, pressure data is continuously collected and the pressure change rate is calculated. For each pair of consecutive time points (t1 and t2), calculate the pressure change rate. After calculating the pressure change rate for the current time period, compare the pressure change rate with the preset threshold. When the pressure change rate is less than the preset threshold, record the current time as the start time. When the pressure change rate is greater than the preset threshold, record the current time as the end time. If the pressure change rate is less than the preset threshold again later, continue to record the current time as the start time. When the pressure change rate is greater than the preset threshold, record the current time as the end time. By repeating this cycle, multiple time periods (i.e., multiple start times and multiple end times corresponding to the multiple start times) can be recorded.

[0089] With such settings, multiple start and end time periods can be continuously recorded to help evaluate the working state of the energy storage exhaust valve. It helps to monitor the energy storage exhaust valve throughout its cycle and provides data support for subsequent test results.

[0090] S114, determine the cumulative time when the pressure does not change within the target time period as the pressure maintenance period.

[0091] It can be understood that within the target time period, multiple start times and end times are continuously monitored and recorded. For each set of records, calculate the time period: time period = end time - start time. Cumulate all the recorded time periods to obtain the pressure maintenance period.

[0092] With such settings, by refining each time period when the pressure does not change, the stability of the energy storage exhaust valve within the target time period can be evaluated more accurately. Each pressure maintenance period is an objective record of the stable operation of the energy storage exhaust valve during that time period, which can help identify whether the energy storage exhaust valve is in a stable state at different time periods.

[0093] S120, obtain the pressure change period. Among them, the pressure change period is the cumulative period during which the pressure of the energy storage exhaust valve in the sealed state is within the target pressure range and periodic pressure changes occur within the target time period.

[0094] It can be understood that the sealing material (such as a rubber gasket) may not fit perfectly due to microscopic unevenness or contaminants, resulting in local adhesion. However, as the pressure continues to act, the sealing material undergoes elastic deformation and may suddenly slide, causing a micron-level gap to open. At this time, the pressure drops suddenly. After the pressure drops, the resilience of the elastic material will cause the gap to close and the pressure to rise again, forming a periodic pressure change in this way.

[0095] Exemplarily, check whether the recorded pressure value is always within the set target range. Use effective methods (such as Fast Fourier Transform FFT, regression analysis, or time series analysis) to test whether the pressure shows recognizable periodic fluctuations within the required time period. For example, if the pressure gradually rises and then gradually drops at two adjacent times, it is determined that a periodic pressure change has occurred. For example, the pressure gradually rises within 1 - 5 minutes, while the pressure gradually drops within 6 - 10 minutes.

[0096] With such a setting, the sealing performance of the valve can be obtained, which helps to evaluate the overall waterproof performance of the energy storage exhaust valve subsequently.

[0097] In a possible implementation, S120, obtaining the pressure change period, includes:

[0098] S121, when it is determined that the energy storage exhaust valve is in a sealed state, determine whether the pressure of the energy storage exhaust valve shows a periodic pressure change according to the obtained pressure data.

[0099] It can be understood that a time window (for example, 5 seconds, 10 seconds, 30 seconds, etc.) can be determined. By means of a sliding window, gradually traverse the entire time series data. Within each window, calculate the mean value of all pressure data points in this window (the mean value u = , where Pi is the pressure value at each moment within the window and n is the window size). Calculate the standard deviation within each window (the standard deviation = , and the standard deviation can reflect the amplitude of pressure fluctuations. A larger standard deviation means a greater pressure change. Analyze whether the means of multiple time periods show an alternating rising or falling trend within a certain time period. For example, the difference sequence △P = P i+1 - P i, if the difference symbol shows periodic alternation (such as +, -, +, -...), then periodicity may exist. If the standard deviation changes periodically over time (such as increasing first and then decreasing), it indicates that the pressure has periodic changes. For example, the extreme points (maximum and minimum values) of the standard deviation in different time periods can be compared. If the time intervals between the extreme points are close, then periodicity may exist. If both the mean and the standard deviation change periodically and the change trends are the same (such as the standard deviation increases when the mean increases), it indicates whether there are periodic pressure changes in the pressure of the energy storage exhaust valve.

[0100] With such a setting, by combining the alternating increase or decrease of the mean with the change of the standard deviation, the periodic behavior of the pressure can be accurately judged, reducing the possibility of subjective judgment.

[0101] In a possible implementation manner, in step S121, after determining that the energy storage exhaust valve is in a sealed state and determining whether there are periodic pressure changes in the pressure of the energy storage exhaust valve according to the pressure data, the waterproof test method for the energy storage exhaust valve further includes:

[0102] S1211, detecting whether the pressure change meets the periodicity requirement according to the pressure data. Among them, the periodicity requirement is that the number of target pressure data among the obtained multiple pressure data exceeds a preset quantity. The number of target pressure data is the number of the nearest pressure data whose harmonic component values of the maximum pressure data and the minimum pressure data exceed a preset value, or the number of the nearest pressure data whose acquisition time interval between the maximum pressure data and the minimum pressure data is less than a set time interval.

[0103] It can be understood that the harmonic component value of the maximum pressure data and the minimum pressure data can be the difference between the maximum pressure data and the minimum pressure data. When the pressure data between the maximum pressure data and the minimum pressure data shows a downward trend, it is expressed as the nearest pressure data. Or, judge whether the acquisition time interval between the maximum pressure data and the minimum pressure data is less than the set time interval. If the time interval is less than the set time interval, it is expressed as the nearest pressure data.

[0104] Exemplarily, the obtained multiple pressure data can be screened according to the periodicity requirement, and it is calculated whether the number of target pressure data exceeds the preset quantity under the condition of meeting the periodicity requirement (that is, the number of target pressure data is used to avoid the evaluation error caused by a single pressure change). When the number of target pressure data exceeds the preset quantity, it indicates that there are periodic pressure changes in the pressure of the energy storage exhaust valve; otherwise, it indicates that there are no periodic pressure changes in the pressure of the energy storage exhaust valve.

[0105] With such settings, by integrating the data analysis of the maximum pressure, minimum pressure, and time interval, the pressure change situation can be identified more effectively, which helps to evaluate the performance of the energy storage exhaust valve, thereby improving the reliability of the evaluation results.

[0106] S1212, when it is detected according to the pressure data that the pressure change meets the periodicity requirement, it is determined that the pressure of the energy storage exhaust valve shows a periodic pressure change.

[0107] It can be understood that when it is detected according to the pressure data that the pressure change meets the periodicity requirement, it means that the number of target pressure data exceeds the preset number, and it is determined that the pressure of the energy storage exhaust valve shows a periodic pressure change.

[0108] With such settings, the periodic behavior of the pressure can be accurately judged, reducing the possibility of subjective judgment.

[0109] S122, when it is determined that the pressure of the energy storage exhaust valve shows a periodic pressure change, record the start time and end time of the current pressure change.

[0110] It can be understood that when the pressure starts to fluctuate, the change in the standard deviation or mean usually shows a significant increase or a sudden change. If the standard deviation starts to increase, or the mean starts to show periodic fluctuations, it can be considered as the start time of the periodic fluctuations. When the pressure fluctuation starts to stabilize or return to near the original state, it indicates the end of the periodic fluctuation, and at this time the standard deviation starts to decrease or the mean fluctuation decreases. Set a threshold for the standard deviation and mean. Repeat this process, and multiple time periods can be recorded (that is, multiple start times of pressure changes and multiple end times corresponding to the multiple start times of pressure changes).

[0111] With such settings, multiple start and end time periods can be continuously recorded to help evaluate the working state of the energy storage exhaust valve. It helps to conduct full-cycle monitoring of the energy storage exhaust valve and provides data support for subsequent test results.

[0112] S123, determine the cumulative time of all pressure changes within the target time period as the pressure change time period.

[0113] It can be understood that within the target time period, continuously monitor and record multiple start times and end times. For each set of records, calculate the time period: time period = end time - start time. Cumulate all the recorded time periods to obtain the pressure change time period.

[0114] With such settings, by refining the time period of each set of pressure changes, the stability of the energy storage exhaust valve within the target time period can be evaluated more accurately. Each set of pressure change time periods is an objective record of the stable operation of the energy storage exhaust valve during that time period, which can help identify whether the energy storage exhaust valve is in a stable state at different time periods.

[0115] S130. Determine the pressure information according to the pressure maintenance period and the pressure change period.

[0116] It can be understood that the pressure information can reflect the ratio between the pressure maintenance period and the pressure change period. If the proportion of the pressure maintenance period is relatively high, it indicates that the energy storage exhaust valve maintains good stability and reliability during operation. On the contrary, if the proportion of the pressure change period is relatively high, it indicates that the energy storage exhaust valve experiences relatively frequent periodic fluctuations during operation, which may be an indication of poor sealing, design problems, or external factor influences.

[0117] With such a setting, by analyzing the ratio of the pressure maintenance period and the pressure change period, the performance of the energy storage exhaust valve within a specific pressure range can be comprehensively evaluated, understanding its stability and reliability under different working conditions, which helps to improve the accuracy and reliability of the waterproof performance determination.

[0118] S200. Obtain the number of change events. Here, the number of change events is the number of water seepages detected when the test device performs a pressure loading action on the energy storage exhaust valve within the target period. A complete pressure loading action includes a pressurization action, a pressure holding action, and a pressure reduction action.

[0119] It can be understood that the pressurization action can be an action of gradually applying pressure to the energy storage exhaust valve until a predetermined value. The pressure holding action can be to hold the pressure at a predetermined value for a period of time to observe whether water seepage occurs. The pressure reduction action can be to gradually release the pressure to the initial state. An effective water seepage can be considered "effective" only when the amount of water seepage reaches a preset standard or threshold, or when it exceeds the normal leakage tolerance range. It can also be that the number of leakage flow data detected within the target radius centered on the leakage coordinate corresponding to the first detected leakage flow data within the set period exceeds a preset number, then it is considered "effective". Among them, the leakage flow data can be the flow data of water seepage, and the leakage coordinate can be the coordinate where the leakage flow data is detected, that is, the coordinate of the leakage point when leakage occurs. Optionally, the coordinate of the leakage point when leakage occurs can be calibrated through a known reference point. For example, during the leakage detection process, the detection device is compared with a known position (such as the pipeline end point, valve, etc.), and the coordinate of the leakage point is determined through distance calculation.

[0120] Exemplarily, during each pressure loading action (pressurization, pressure holding, depressurization), the test device can monitor whether a water seepage event occurs. For example, it can monitor whether there is water penetration or outflow through sensors (such as a flow meter or a humidity sensor). Each time an effective water seepage is detected, a water seepage quantity is recorded, that is, a change event quantity is recorded. During the pressure loading action, all effective water seepage events are recorded, and finally, the change event quantity is statistically counted according to the occurrence quantity of the water seepage events. If there is water seepage in multiple stages (pressurization, pressure holding, depressurization) of the same pressure loading action, the quantity of water seepage events needs to be recorded and accumulated separately.

[0121] With such a setting, by obtaining the quantity of water seepage detected during the pressure loading action of the test device on the energy storage exhaust valve within the target time period, the leakage situation of the valve under different pressure conditions can be quantified, which helps to provide data support for subsequent determination of whether the waterproof performance of the energy storage exhaust valve meets the standard.

[0122] In a possible implementation manner, S200, obtaining the change event quantity includes:

[0123] S210, during the test, whenever leakage flow data is detected, obtain the quantity of leakage events, the leakage occurrence time when the leakage flow data is detected, and the leakage coordinates corresponding to the detected leakage flow data.

[0124] It can be understood that the leakage flow data can be the flow data of water seepage or the data of detected water seepage. A leakage flow threshold can be defined. For example, when the flow rate exceeds a certain preset value (such as 0.01 L / min), it can be determined as the data of detected water seepage. The quantity of leakage events can be the quantity of detected leakage flow data. Whenever the leakage flow data is detected, the counter can be incremented by 1. The leakage coordinates can be the coordinates of the detected leakage flow data.

[0125] Exemplarily, the leakage flow data can be obtained through a flow sensor. The quantity of leakage events can be obtained by incremental recording through a counter. The leakage coordinates can be real-time fed back by a position sensor. And these data are recorded in the memory, as shown in Table 1:

[0126] Table 1

[0127]

[0128] With such a setting, by recording the quantity of leakage events, the time and coordinates of leakage occurrence, the location and time period of leakage occurrence can be accurately located, providing substantial data support for subsequent analysis and decision-making.

[0129] S220. Based on the leakage occurrence time and leakage coordinates of the detected leakage flow data corresponding to the number of leakage events, determine whether effective water seepage is detected during the pressure loading operation of the test device on the energy storage exhaust valve.

[0130] It can be understood that the test period can be determined according to the leakage occurrence time and the set period. During the test period, determine how many of the leakage events corresponding to the number of leakage events have leakage coordinates within the target range (for example, the range near the test component of the energy storage exhaust valve, which can be set according to the operator's needs). For each leakage event, check whether the leakage occurrence time is between the determined test periods. When the leakage occurrence time is within the test period and the leakage coordinates corresponding to the number of leakage events are within the target range, if the number of leakage events with leakage coordinates within the target range exceeds the preset number, it can be determined that effective water seepage is detected during the pressure loading operation of the test device on the energy storage exhaust valve; otherwise, it can be determined that no effective water seepage is detected during the pressure loading operation of the test device on the energy storage exhaust valve.

[0131] For example, the set period is 1 minute, the preset number is 2, and the current test time is 7:00. Then the test period is 6:59 - 7:00. The number of leakage events with leakage coordinates within the target range during the test period is 4 (the number of leakage events during the test period is 6, that is, the number of leakage events with leakage coordinates not within the target range during the test period is 2). Then it can be determined that effective water seepage is detected during the pressure loading operation of the test device on the energy storage exhaust valve.

[0132] With such settings, by setting a specific time period and target range, it is possible to more accurately determine whether there is effective water seepage and reduce the possibility of misjudgment caused by accidental water seepage occurring once.

[0133] S230. When it is determined that effective water seepage is detected during the pressure loading operation of the test device on the energy storage exhaust valve, accumulate the number of effective leaks.

[0134] It can be understood that when it is determined that effective water seepage is detected during the pressure loading operation of the test device on the energy storage exhaust valve, the number of leakage events with leakage coordinates within the target range during the test period can be accumulated.

[0135] For example, the number of leakage events during the test period is 6, the number of leakage events with leakage coordinates within the target range during the test period is 4, and the number of leakage events with leakage coordinates not within the target range during the test period is 2. Then the number of leakage events with leakage coordinates within the target range during the test period, which is 4, can be accumulated.

[0136] With such a setting, by accumulating the number of valid leakage events, the occurrence trend of effective water seepage during the test period can be monitored in real time, providing data support for subsequent decision-making.

[0137] In a possible implementation manner, in step S230, before accumulating the number of valid leaks when it is determined that effective water seepage is detected during the pressure loading action of the test device on the energy storage exhaust valve, the waterproof test method for the energy storage exhaust valve further includes:

[0138] S231, based on the leakage occurrence time and leakage coordinates of the detected leakage flow data corresponding to the number of leakage events, determine whether the number of leakage events meets the preset accumulation requirement. Among them, the preset accumulation requirement is that the number of detections of the leakage flow data corresponding to the number of leakage events within the target range exceeds the preset number within the set time period, and the target range is the target radius range with the leakage coordinates corresponding to the first detected leakage flow data within the set time period as the reference point.

[0139] It can be understood that the target range can be a radius range determined based on the leakage coordinates when the leakage flow data is first detected within the set time period as the reference point. The target range can be a spherical range. If the leakage coordinates are within this range, it is a "leakage event within the target range". The radius can be a preset fixed value or can be dynamically adjusted according to the leakage flow or the needs of the operator. For each leakage event within the set time period, check whether its leakage coordinates are within the calculated target range above. The specific judgment can be calculated using a formula: Distance = , where (x1, y1, z1) are the leakage coordinates of the first detected leakage event, and (x2, y2, z2) are the leakage coordinates of the current leakage event. If the distance is less than or equal to the target radius, the leakage event is within the target range. Within the set time period, count the number of all qualified leakage events (that is, the leakage events with leakage coordinates within the target range and the number of leakage events with leakage coordinates within the target range exceeds the preset number).

[0140] With such a setting, qualified leakage events can be effectively screened out, avoiding the influence of invalid leakage events on the test results, thereby improving the accuracy of the test.

[0141] S232, when it is determined that the number of leakage events meets the preset accumulation requirement, determine that effective water seepage is detected during the pressure loading action of the test device on the energy storage exhaust valve.

[0142] It can be understood that when it is determined that the number of leakage events meets the preset accumulation requirement, it means that the leakage events with leakage coordinates within the target range and the number of leakage events with leakage coordinates within the target range exceeds the preset number. Therefore, it can be determined that effective water seepage is detected during the pressure loading action of the test device on the energy storage exhaust valve.

[0143] With such a setting, it is possible to more accurately determine whether there is effective water seepage and reduce the possibility of misjudgment caused by accidental water seepage occurring once.

[0144] S240. Determine the number of change events as the cumulative number of effective leaks within the target time period.

[0145] It can be understood that the number of leak events with leak coordinates within the target range during the test period can be determined as the number of change events.

[0146] Exemplarily, determine the number of change events as 4, which is the number of leak events with leak coordinates within the target range during the test period.

[0147] With such a setting, by accumulating the number of effective leak events, the occurrence trend of effective water seepage during the test period can be monitored in real time, providing data support for subsequent decision-making.

[0148] S300. Determine the number of pressure cycles. Herein, the number of pressure cycles is the number of cyclic tests of the pressure loading actions performed by the test device on the energy storage exhaust valve within the target time period.

[0149] It can be understood that within the target time period, pressure cycling is carried out according to the set pressure loading procedure. After each pressure loading action (pressurization, pressure holding, depressurization) is completed, it is regarded as one pressure cycle completed. During the target time period, each complete pressure loading action (i.e., a combination of a pressurization, pressure holding, and depressurization action) is recorded. For each cycle completed, the count is incremented by 1, and the number of cycles throughout the target time period is accumulated to finally obtain the number of pressure cycles.

[0150] Exemplarily, if the target time period has ended but the test device is still in the middle of the pressurization, pressure holding, or depressurization stage, the influence degree of the incomplete pressure cycle on the test result can be analyzed (for example, compare the data obtained when the previous complete pressure cycle was completed with the result of the current incomplete test. Through the comparison of historical data, the deviation degree of the incomplete pressure cycle on the result can be evaluated). If the influence of this incomplete cycle on the overall test result is small, it can be stated in the reported result that its influence on the final data accuracy is negligible. If the incomplete pressure cycle may affect the accuracy of the final result, the reported result can request subsequent tests. For example, it can be recommended to extend the test time period or perform a complete pressure cycle again.

[0151] With such a setting, by determining the number of cyclic tests of the pressure loading actions performed by the test device on the energy storage exhaust valve within the target time period, it helps to test the performance of the exhaust valve during multiple cycles, thereby reducing random errors and thus helping to improve the accuracy of the test result.

[0152] S400, calculate the failure ratio of the number of leakage events to the number of pressure cycles.

[0153] It can be understood that the failure ratio can be the ratio between the number of leakage events and the number of pressure cycles.

[0154] With such a setting, it can more intuitively show the proportion of leakage events occurring in each pressure cycle, which helps to reflect the performance of the energy storage exhaust valve during the test.

[0155] S500, based on the pressure information and the failure ratio, determine whether the waterproof performance of the tested energy storage exhaust valve meets the standard.

[0156] It can be understood that define the maximum pressure change limit value that the energy storage exhaust valve should maintain within the specified pressure range. For example, set a maximum allowable pressure change range, and exceeding this range may indicate poor sealing performance. Determine an acceptable failure ratio range. For example, set a maximum failure ratio (such as 5%, 10%, etc.), and exceeding this preset ratio indicates that the waterproof performance does not meet the standard. If the pressure information is stable within the standard pressure range and the failure ratio is within the acceptable failure ratio range, then it is determined that the waterproof performance of the energy storage exhaust valve meets the standard. If the pressure information is stable within the standard pressure range while the failure ratio is lower than the preset ratio, then it is determined that the waterproof performance of the energy storage exhaust valve does not meet the standard.

[0157] With such a setting, based on multiple factors such as the pressure change situation of the tested energy storage exhaust valve under fluid when in a sealed state during the target period, the number of effective water seepage detected during the pressure loading action of the test device on the energy storage exhaust valve during the target period, and the number of cycle tests of the pressure loading action of the test device on the energy storage exhaust valve during the target period, determine whether the waterproof performance of the tested energy storage exhaust valve meets the standard, avoiding misjudgment that may be caused by a single indicator (such as only relying on pressure), making the determination of the waterproof performance more accurate and reliable.

[0158] In a possible implementation manner, S500, based on the pressure information and the failure ratio, determine whether the waterproof performance of the tested energy storage exhaust valve meets the standard, including:

[0159] S510, based on the pressure information and the failure ratio of each batch in N consecutive test batches, determine whether the waterproof performance of the tested energy storage exhaust valve meets the standard. Where N is a positive integer greater than 1.

[0160] It can be understood that the N test batches can be consecutive test batch numbers, where N is greater than 1, that is, at least two batches of tests are carried out. Traverse each batch (a total of N batches), the corresponding pressure information and failure ratio. If the failure ratios of all batches are lower than the preset ratio, and the pressure information reflects a relatively high proportion of the pressure maintenance period (for example, higher than 70%), the waterproof performance can be considered qualified. If the failure ratio of any batch exceeds the preset ratio, or the pressure information reflects a low proportion of the pressure maintenance period, the waterproof performance is determined to be unqualified.

[0161] With such a setting, by comprehensively analyzing the test data of multiple batches, the influence of single - test error can be reduced. If the failure ratio of only one test batch is on the high side or the pressure information is abnormal, the overall judgment may be affected. Multiple tests can provide more representative and stable conclusions, which helps to ensure a more accurate evaluation of the waterproof performance.

[0162] In a possible implementation, S510, determining whether the waterproof performance of the measured energy - storage exhaust valve meets the standard according to the pressure information and failure ratio of each batch in N consecutive test batches, includes:

[0163] S511, when the value of the pressure information of each batch in N consecutive test batches exceeds the target value and the failure ratio exceeds the preset ratio, determining that the waterproof performance of the measured energy - storage exhaust valve does not meet the standard.

[0164] It can be understood that the value of the pressure information can be the proportion of the pressure maintenance period. For example, the value of the pressure information = the pressure maintenance period ÷ the pressure change period. When the value of the pressure information of each batch in N consecutive test batches exceeds the target value and the failure ratio exceeds the preset ratio, it indicates that the waterproof performance is unqualified, that is, it is determined that the waterproof performance of the measured energy - storage exhaust valve does not meet the standard.

[0165] With such a setting, by comprehensively analyzing the test data of multiple batches, the influence of single - test error can be reduced, which helps to ensure a more accurate evaluation of the waterproof performance.

[0166] It should be understood that the magnitudes of the sequence numbers of the steps in the above - mentioned embodiments do not mean the order of execution.
