[0001] The present application relates to the technical field of vehicle safety, in particular to a dew verification method and device, a terminal and a storage medium. BACKGROUND
[0002] In the domain controller thermal management scheme, some schemes connect the domain controller and the battery pack system in parallel, so the inlet water temperature of the domain controller changes with the change of the inlet water temperature of the battery pack. Generally, the vehicle has two cooling modes. One is that the cooling liquid is cooled by the front end radiator of the vehicle, and at this time the cooling liquid temperature is equal to the ambient temperature, which is suitable for normal or low temperature use environment. The other is that the cooling liquid is cooled by the cooler of the vehicle, and a lower cooling liquid temperature can be obtained, generally the cooling liquid temperature is equal to 20 DEG C, which is suitable for high temperature use environment. When the system cooler is involved, the temperature of the cooling liquid is low, and at this time if the domain controller is in a high temperature and high humidity environment, there is a risk of dew.
[0003] At present, the survival ability of the domain controller in the wet heat climate is mainly verified by the wet heat cycle test, that is, in high humidity, the condensate water is generated in the domain controller by temperature change, and then the damage of the condensate water to the domain controller is verified.
[0004] However, the above method does not consider the actual application scene of the vehicle, and cannot be applied to the dew verification of the domain controller of the vehicle in the actual working condition. SUMMARY

[0030] If the domain controller's housing temperature is above the dew point, then no condensation occurs on the domain controller.
[0031] In one possible implementation, the method also includes:
[0032] If the domain controller's housing temperature is less than or equal to the dew point, then a simulation experiment is conducted to verify whether condensation will occur on the domain controller.

[0054] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0055] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.
[0056] In one embodiment, such as Figure 1 As shown, a condensation verification method is provided, including the following steps:
[0057] Step S101: Determine the condensation conditions of the domain controller based on the preset enthalpy-humidity diagram.
[0058] The preset enthalpy-humidity diagrams in this application include, but are not limited to, humid air enthalpy-humidity diagrams.
[0059] Taking a preset enthalpy-humidity diagram as an example, the enthalpy-humidity diagram of humid air includes multiple contour lines, such as isohumidity lines, isotherms, isenthalpic lines, and isorelative humidity lines. Specifically: Isohumidity lines: The humidity is the same on these lines, and their parallel lines are also isohumidity lines. For the same moisture content, as air temperature increases, relative humidity increases. Isotherms: The temperature is the same on these lines, and their parallel lines are also isotherms. Isenthalpic lines: The enthalpy value is the same on these lines, and their parallel lines are also isenthalpic lines. Isorelative humidity lines: The relative humidity is the same on these lines, and their parallel lines are also isorelative humidity lines.
[0060] According to the enthalpy-humidity diagram of humid air, the condensation conditions of the domain controller include: water vapor penetrating into the domain controller to form high humidity gas, and when the high temperature and high humidity gas encounters the domain controller and the temperature drops, the relative humidity will exceed 100%.
[0061] Step S102: Determine the condensation scenario of the domain controller based on the condensation conditions of the domain controller.
[0062] By defining the condensation conditions for the domain controller, we can design condensation scenarios for the entire vehicle in real-world application scenarios. In other words, we can verify the condensation performance of the domain controller under different actual operating conditions of the vehicle. These different actual operating conditions correspond to different condensation scenarios.
[0063] Specifically, the condensation scenarios of the domain controller include a first condensation scenario and a second condensation scenario. The first condensation scenario is caused by condensation when the inlet water temperature of the domain controller is lower than the preset inlet water temperature, and the second condensation scenario is caused by condensation when the ambient temperature of the domain controller changes.
[0064] The second condensation scenario includes a third condensation scenario and a fourth condensation scenario. The third condensation scenario is the condensation that occurs when the domain controller moves from a first preset temperature environment to a second preset temperature environment, where the first preset temperature is lower than the second preset temperature, such as when the domain controller moves from a low-temperature environment to a high-temperature environment. The fourth condensation scenario is the condensation that occurs when the domain controller moves from a third preset temperature environment to a fourth preset temperature environment, where the third preset temperature is higher than the fourth preset temperature, such as when the domain controller moves from a high-temperature environment to a low-temperature environment.
[0065] Step S103: In a condensation scenario, perform a condensation test on the domain controller to verify whether condensation occurs on the domain controller.
[0066] In one possible implementation, the condensation scenario is designated as the first condensation scenario. In this scenario, a condensation test is performed on the domain controller to verify whether condensation has occurred. This includes: in the first condensation scenario, after the vehicle has been driven for a preset period of time, cooling water is introduced into the domain controller in the vehicle. The temperature and humidity of the environment in which the domain controller is located are then obtained. Based on the temperature and humidity of the environment in which the domain controller is located, the dew point is determined, and then it is determined whether the casing temperature of the domain controller is greater than the dew point. Here, the casing temperature of the domain controller is the temperature of the cooling water. If the casing temperature of the domain controller is greater than the dew point, then condensation has not occurred on the domain controller.
[0067] Taking Guangzhou's summer operating conditions as an example, after the vehicle has been running for a period of time, coolant is circulated into the domain controller in the vehicle. Figure 2 As shown, the ambient temperature of the domain controller is 40℃ and the relative humidity is 90%, i.e. Figure 2 Point A is shown in the diagram. (Through...) Figure 2 The enthalpy-humidity diagram can be calculated to obtain:
[0068] Without cooling water: When the internal air temperature of the domain controller rises to 85℃, the moisture content remains constant at 43.6g / kg, while the relative humidity decreases to 11.5%. Figure 2 Point B shown; when cooling water is supplied: due to the inlet water temperature of 70℃, the air temperature inside the domain controller will drop to 70℃, the moisture content will remain constant at 43.6g / kg, and the relative humidity will increase to 21.3%, i.e. Figure 2 Point C is shown in the diagram.
[0069] When cooling water is introduced, the ambient temperature is 40°C and the relative humidity is 90%, corresponding to a dew point of 38°C. The enclosure temperature is the same as the cooling water temperature, i.e., the inlet water temperature is 70°C. Therefore, since the enclosure temperature of the domain controller is greater than the dew point, no condensation occurs on the domain controller.
[0070] In addition, since the relative humidity does not exceed 100% in actual vehicles when cooling water is supplied, there are no conditions for condensation.
[0071] In one possible implementation, the condensation scenario is the third condensation scenario. In the condensation scenario, a condensation test is performed on the domain controller to verify whether condensation occurs on the domain controller. This includes: first, determining the temperature and humidity of the environment where the domain controller is located based on the first preset temperature and the second preset temperature; then, determining the dew point based on the temperature and humidity of the environment where the domain controller is located; and then determining whether the housing temperature of the domain controller is greater than the dew point. The housing temperature is the first preset temperature. If the housing temperature of the domain controller is greater than the dew point, then the domain controller has not experienced condensation.
[0072] For example, the third condensation scenario simulates a vehicle driving into an underground parking garage in summer. It considers more demanding conditions than reality, with an ambient temperature of 50°C and a relative humidity of 95%, and then moves the vehicle from the 50°C environment to a 10°C environment.
[0073] like Figure 3 As shown, moving a vehicle from a 50°C environment to a 10°C environment mainly involves three stages: Stage 1 involves raising the ambient temperature from RT°C to 50°C; Stage 2 involves bringing the vehicle to a complete stop at an ambient temperature of 50°C, a relative humidity of 95%, and an inlet water temperature of 70°C for the domain controller; Stage 3 involves lowering the ambient temperature to 10°C and the relative humidity to 95%. RT is between 10°C and 50°C.
[0074] After the three stages are completed, the ambient temperature is 10℃ and the relative humidity is 95%. The dew point can be found in a table using these ambient temperature and relative humidity, which is 49℃. Next, it is determined whether the domain controller's casing temperature (assuming it is 50℃) is greater than the dew point of 49℃. If the domain controller's casing temperature is greater than the dew point, then no condensation has occurred on the domain controller. If the domain controller's casing temperature (assuming it is 48℃) is less than the dew point of 49℃, then a simulation experiment is conducted to verify whether condensation will occur on the domain controller.
[0075] In addition, when stage 3 is reached, the location where the test strip is attached to the domain controller, such as the casing or chip, can be detected. When the test strip at this location changes from white to red, it indicates that condensation has occurred at this location.
[0076] In one possible implementation, the condensation scenario is the fourth condensation scenario. In the condensation scenario, a condensation test is performed on the domain controller to verify whether condensation occurs on the domain controller. This includes: first, determining the temperature and humidity of the environment where the domain controller is located based on the third and fourth preset temperatures; then, determining the dew point based on the temperature and humidity of the environment where the domain controller is located; and finally, determining whether the housing temperature of the domain controller is greater than the dew point. The housing temperature is the third preset temperature. If the housing temperature of the domain controller is greater than the dew point, then condensation has not occurred on the domain controller.
[0077] For example, the fourth condensation scenario simulates a vehicle that has been sitting at low temperatures in winter and then driven to a car wash for a short period of time. It considers conditions more severe than reality, with an ambient temperature of -10°C and a relative humidity of 90%, and then moves the vehicle from the -10°C environment to a 30°C environment.
[0078] like Figure 4As shown, moving a vehicle from a -10°C environment to a 30°C environment mainly involves three stages: Stage 1 involves lowering the ambient temperature from RH°C to 10°C; Stage 2 involves bringing the vehicle to a complete stop at -10°C; and Stage 3 involves raising the ambient temperature to 30°C with a relative humidity of 90%. RT is between -10°C and 30°C.
[0079] After the three stages are completed, the ambient temperature is 30℃ and the relative humidity is 90%. The dew point can be found in a table using these ambient temperature and relative humidity values; it is 28.2℃. Next, it is determined that the domain controller's casing temperature (-10℃) is less than the dew point of 28.2℃. If the domain controller's casing temperature is less than the dew point, a simulation experiment is conducted to verify whether condensation will occur on the domain controller. If the domain controller's casing temperature (assumed to be 30℃) is greater than the dew point of 28.2℃, then condensation has not occurred on the domain controller.
[0080] In addition, when stage 3 is reached, the location where the test strip is attached to the domain controller, such as the casing or chip, can be detected. When the test strip at this location changes from white to red, it indicates that condensation has occurred at this location.
[0081] This invention provides a condensation verification method, comprising: first, determining the condensation conditions of a domain controller based on a preset enthalpy-humidity diagram; then, determining the condensation scenarios of the domain controller based on the condensation conditions; and finally, performing a condensation test on the domain controller under the condensation scenarios to verify whether condensation occurs on the domain controller. This invention considers the actual application scenarios of a complete vehicle, verifying the condensation situation of the domain controller under different condensation scenarios, and then determining the location of condensation and whether it will affect the chip through the condensation situation of the domain controller, thereby optimizing the design of the domain controller.
