Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a sealing device and a sealing monitoring method. Background Art

[0002] Power batteries are the core powertrain of new energy vehicles. As new energy vehicles develop towards greater integration and fewer components, CTB batteries are rapidly being promoted and applied. Compared to traditional batteries, CTB batteries offer advantages such as high integration, lightweight, and high strength.

[0003] Since the battery pack cover is used instead of the traditional body floor, during the vehicle production, use, battery disassembly and maintenance processes, it is necessary to ensure that the battery pack cover and the body are reliably sealed to ensure that external liquids of the entire vehicle do not invade the passenger compartment. Otherwise, seal failure will seriously endanger the safety of the passenger compartment of the entire vehicle in harsh working conditions such as wading.

[0004] At present, the industry does not have an effective detection method for the sealing interface between the battery and the entire vehicle in the CTB integrated form. It is impossible to ensure that the failure of the seal is reported in a timely manner to remind the user to quickly deal with the failure, which lacks safety protection for the passenger compartment. Summary of the Invention

[0005] In view of this, the embodiments of the present application provide a sealing device and a sealing monitoring method, which can ensure that the sealing performance of the CTB battery pack and its connection with the vehicle body are effectively monitored, thereby improving the safety and reliability of the vehicle.

[0006] The technical solution of the embodiment of the present application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a sealing device for a CTB battery pack, wherein the upper cover of the CTB battery pack is a vehicle body floor. The device includes:

[0008] A first sealing module is provided between the upper cover and the vehicle body door beam. The first sealing module is annular and is used to seal the vehicle body and the CTB battery pack to prevent liquid from outside the vehicle from seeping into the passenger compartment.

[0009] The device also includes a first sealing monitoring module, which is used to monitor the first sealing condition of the first sealing module. The signal output end of the first sealing monitoring module is connected to the signal input end of the signal processing module through a first signal transmission module. The signal processing module is used to judge the sealing of the entire vehicle based on the first sealing condition.

[0010] In a possible implementation, the device further includes:

[0011] A second sealing module is arranged between the upper cover and the vehicle body door beam and located within the first sealing monitoring module. The second sealing module is annular and is used to perform secondary sealing on the vehicle body and battery pack to prevent external liquid of the vehicle from breaking through the first sealing module and seeping into the passenger compartment inside the vehicle.

[0012] In a possible implementation, the device further includes:

[0013] The second sealing monitoring module is used to monitor the second sealing condition of the second sealing module. The signal output end of the second sealing monitoring module is connected to the signal input end of the signal processing module through the second signal transmission module. The signal processing module is used to judge the sealing of the entire vehicle based on the first sealing condition and the second sealing condition.

[0014] In a possible implementation, the first sealing monitoring module includes a water-sensitive feature and outputs a signal when the first sealing monitoring module comes into contact with liquid.

[0015] In a possible implementation, the second sealing monitoring module includes a water-sensitive feature and outputs a signal when the second sealing monitoring module contacts liquid.

[0016] In a second aspect, an embodiment of the present application further provides a sealing monitoring method, which is applied to a CTB battery pack, wherein the upper cover of the CTB battery pack is a vehicle body floor, and the method comprises:

[0018] contacting each of the at least one liquid with the first sealing module and the second sealing module, respectively, and calibrating the first sealing monitoring module and the second sealing monitoring module according to the composition and hazard level of each liquid;

[0019] The sealing performance of the entire vehicle is monitored based on the calibrated sealing device.

[0020] In one possible implementation, the method further includes:

[0021] When the first sealing module outputs a signal and the second sealing module does not output a signal, the signal processing module determines that the first sealing module has failed and the external liquid has not invaded the passenger compartment, and reports a first-level warning signal through the signal processing module;

[0022] When the first sealing module outputs a signal and the second sealing module also outputs a signal, if the liquid components contacted by the first sealing module and the second sealing module are the same or are within a preset error range, the signal processing module determines that both the first sealing module and the second sealing module have failed, and there is external liquid invading the passenger compartment, and reports a third-level warning signal through the signal processing module; if the liquid components contacted by the first sealing module and the second sealing module are different or are outside the preset error range, the signal processing module determines that the first sealing module has failed, the external liquid has not invading the passenger compartment, the second sealing module has not failed, and the liquid inside the vehicle has contacted the second sealing monitoring module, and reports a second-level warning signal through the signal processing module;

[0023] When the first sealing module outputs a signal and the second sealing module also outputs a signal, and the time when the first sealing monitoring module outputs a signal is later than the time when the second sealing monitoring module outputs a signal, if the liquid components contacted by the first sealing module and the second sealing module are the same or are within a preset error range, the signal processing module determines that the first sealing module has not failed, the second sealing module has failed, and the first sealing module is corroded by liquids inside and outside the vehicle at the same time, and reports a secondary warning signal through the signal processing module; if the liquid components contacted by the first sealing module and the second sealing module are different or are outside the preset error range, the signal processing module determines that the first sealing module has failed, the second sealing module has not failed, and the second sealing module is corroded by liquids inside and outside the vehicle at the same time, and reports a secondary warning signal through the signal processing module;

[0024] When the first sealing module does not output a signal and the second sealing module outputs a signal, the signal processing module determines that no liquid outside the vehicle has intruded into the passenger compartment, the signal processing module does not report a warning signal, and the signal processing module sends a reminder signal to remind passengers to clean up the leaked liquid in the passenger compartment;

[0025] When the first sealing module does not output a signal and the second sealing module also does not output a signal, the signal processing module determines that no liquid outside the vehicle has invaded the passenger compartment and there is no liquid leakage in the vehicle, and the signal processing module does not report a warning signal and does not send a reminder signal.

[0026] In a third aspect, an embodiment of the present application further provides a sealing monitoring device, characterized in that it is applied to a CTB battery pack, wherein the upper cover of the CTB battery pack is a vehicle body floor, and the device comprises:

[0027] a determination module, configured to determine at least one liquid based on a liquid intrusion condition;

[0028] a calibration module, configured to contact each of the at least one liquid with the first sealing module and the second sealing module, respectively, and calibrate the first sealing monitoring module and the second sealing monitoring module, respectively, according to the composition and hazard level of each liquid;

[0029] The monitoring module is used to monitor the sealing performance of the entire vehicle based on the calibrated sealing device.

[0030] In a fourth aspect, an embodiment of the present application further provides an electronic device comprising: a processor, a storage medium and a bus, wherein the storage medium stores machine-readable instructions executable by the processor. When the electronic device is running, the processor communicates with the storage medium through the bus, and the processor executes the machine-readable instructions to execute the sealing monitoring method described in any one of the first aspects.

[0031] In a fifth aspect, an embodiment of the present application further provides a computer-readable storage medium, on which a computer program is stored. When the computer program is run by a processor, the sealing monitoring method described in any one of the first aspects is executed.

[0032] The embodiments of the present application have the following beneficial effects:

[0033] (1) Enhanced vehicle sealing performance: By designing a dual sealing structure of the first and second sealing modules, the sealing performance of the CTB battery pack and its connection with the vehicle body is significantly improved. This dual protection mechanism can effectively prevent external liquids from invading the passenger compartment, protecting passengers from water intrusion, while ensuring a dry environment inside the battery pack, preventing electrical failures and safety hazards.

[0034] (2) Real-time monitoring and early warning: The introduction of the first and second sealing monitoring modules, combined with water-sensitive characteristics, enables real-time monitoring of sealing performance. Once the seal fails, the monitoring module will immediately output a signal, and the signal processing module will respond quickly. This real-time monitoring and early warning mechanism can promptly detect and resolve potential sealing problems, preventing further liquid intrusion and causing greater losses.

[0035] (3) Accurate judgment and graded warning: The seal monitoring method not only focuses on the failure of the sealing module, but also accurately judges the cause of the seal failure by analyzing the liquid composition and intrusion sequence. Depending on the failure situation, the system can report different levels of warning signals, providing maintenance personnel with accurate fault information and guiding them to take appropriate countermeasures.

[0036] (4) Improve user experience: Through the intelligent monitoring and early warning system, users can timely understand the sealing status of the vehicle and avoid accidents caused by sealing problems. At the same time, the system can also send reminder signals in specific situations (such as liquid leakage in the car) to remind passengers to pay attention and take appropriate cleaning measures, thereby improving the user experience and satisfaction.

[0037] (5) Improved vehicle safety and reliability: The dual-sealing structure and real-time monitoring and warning mechanism enhance vehicle safety and reliability.

[0052] See also Figure 1 and Figure 2 , Figure 1: is a schematic structural diagram of the sealing device provided in an embodiment of the present application (top view), Figure 2 Schematic diagram of the structure of the sealing device provided in the embodiment of the present application (cross-sectional view), as shown in FIG. Figure 1 and Figure 2 As shown, a sealing device is applied to a CTB battery pack, wherein the upper cover of the CTB battery pack is a vehicle body floor, and the device comprises:

[0053] A first sealing module (sealing module 1) is provided between the upper cover and the vehicle body door beam. The first sealing module is annular and is used to seal the vehicle body and the CTB battery pack to prevent external liquid from entering the passenger compartment of the vehicle;

[0054] The device also includes a first sealing monitoring module (sealing monitoring module 1), which is used to monitor the first sealing condition of the first sealing module. The signal output end of the first sealing monitoring module is connected to the signal input end of the signal processing module through a first signal transmission module (signal transmission module 1), and the signal processing module is used to judge the sealing of the entire vehicle based on the first sealing condition.

[0055] The first sealing module is set between the upper cover of the CTB battery pack (i.e. the vehicle body floor) and the vehicle body door beam, forming a ring structure. This layout not only ensures the integrity of the seal, but also makes full use of the vehicle body structure and maximizes the use of space. Its main function is to prevent liquids outside the vehicle (such as rainwater, car wash water, etc.) from seeping into the passenger compartment through the gap between the vehicle body and the battery pack, thereby protecting passengers from water intrusion. At the same time, it also maintains the dryness of the internal environment of the battery pack to prevent electrical failures or safety hazards caused by water intrusion.

[0056] The first seal monitoring module is responsible for real-time monitoring of the sealing status of the first sealing module, specifically checking for leaks or poor sealing. This function is crucial for promptly identifying and addressing potential sealing issues, helping to prevent further losses caused by seal failure. Its signal output is connected to the signal processing module via the first signal transmission module, enabling rapid and accurate transmission of monitoring data. This design ensures the real-time and accuracy of monitoring results, providing a reliable basis for subsequent seal assessment.

[0057] The signal processing module, the core of the entire seal monitoring system, is responsible for receiving, processing, and analyzing data from the primary seal monitoring module. Using pre-set algorithms and logical analysis, the module accurately assesses the vehicle's sealing performance. If a sealing issue is detected, it immediately issues an alarm or takes appropriate countermeasures. This feature not only improves vehicle safety and reliability, but also provides users with a more convenient and intelligent driving experience. Through real-time monitoring and early warning, users can promptly understand the vehicle's sealing status and avoid unexpected situations caused by sealing issues.

[0058] This sealing device and monitoring system designed for CTB battery packs effectively improves the waterproof performance and overall sealing of electric vehicles through highly integrated design and intelligent monitoring methods, providing passengers with a safer and more comfortable riding environment.

[0059] In some embodiments, the apparatus further comprises:

[0060] A second sealing module (sealing module 2) is arranged between the upper cover and the vehicle body door beam and located within the first sealing monitoring module. The second sealing module is annular and is used to perform secondary sealing on the vehicle body and battery pack to prevent external liquid of the entire vehicle from breaking through the first sealing module and seeping into the passenger compartment inside the vehicle.

[0061] The second sealing module is arranged between the upper cover of the CTB battery pack (i.e. the vehicle body floor) and the vehicle body door beam, and in particular, it is located inside the first sealing monitoring module or in an annular position closely adjacent to it. This layout ensures that even when the first sealing module fails or penetrates to some extent, the second sealing module can serve as an additional barrier to prevent external liquids from further invading the passenger compartment. The main function of the second sealing module is to provide secondary sealing protection. As a supplement and enhancement to the first sealing module, it is intended to prevent external liquids from continuing to invade the vehicle after breaking through the first line of defense, thereby ensuring that the passenger compartment is completely dry and safe. This double sealing design significantly improves the overall waterproof performance and sealing reliability of the vehicle.

[0062] The first and second sealing modules together form a multi-layered sealing system for the CTB battery pack and its connection to the vehicle body. The first sealing module serves as the primary barrier, blocking most external liquid intrusion; the second sealing module, a backup line of defense, provides additional protection for the vehicle's sealing performance. Together, these two modules ensure the vehicle's sealing and safety in a variety of adverse weather and road conditions.

[0063] The introduction of a second sealing module significantly improves the vehicle's sealing performance. Even in the most adverse circumstances, such as when the first sealing module partially fails due to severe impact or wear, the second sealing module can promptly take over and continue to function, preventing external liquids from invading the passenger compartment. This design not only enhances vehicle safety and reliability, but also provides users with a more secure and worry-free driving experience.

[0064] In summary, the addition of the second sealing module further improves the sealing system of the CTB battery pack and its connection with the vehicle body, providing more comprehensive and reliable waterproof protection for the entire vehicle.

[0065] In some embodiments, the apparatus further comprises:

[0066] The second sealing monitoring module (sealing monitoring module 2) is used to monitor the second sealing condition of the second sealing module. The signal output end of the second sealing monitoring module is connected to the signal input end of the signal processing module through the second signal transmission module (signal transmission module 2). The signal processing module is used to judge the sealing of the entire vehicle based on the first sealing condition and the second sealing condition.

[0067] The second seal monitoring module is specifically designed to monitor the seal of the second sealing module, specifically to check whether it effectively prevents the intrusion of external liquids. Similar to the first seal monitoring module, the second seal monitoring module can sense and provide feedback on the sealing status of the second sealing module in real time, ensuring that any potential leaks are detected promptly.

[0068] The second seal monitoring module is typically installed near the second sealing module to accurately assess its sealing effectiveness. Its signal output is connected to the signal input of the signal processing module via the second signal transmission module, ensuring rapid and stable transmission of monitoring data. Together, the first and second seal monitoring modules form a dual monitoring system for the vehicle's sealing performance. They monitor sealing modules at different levels, ensuring a comprehensive assessment of the vehicle's sealing performance from multiple angles and levels. If any monitoring module detects a sealing issue, it transmits the relevant information to the signal processing module via the signal transmission module for processing.

[0069] The signal processing module, the hub of the entire seal monitoring system, receives and processes data from the primary and secondary seal monitoring modules. By comprehensively analyzing the primary and secondary seal conditions, the signal processing module can more accurately determine the vehicle's sealing performance and, when necessary, issue an alarm or take appropriate countermeasures.

[0070] The addition of the second seal monitoring module further enhances the vehicle's sealing performance monitoring capabilities. It enables the vehicle to more promptly and accurately detect and resolve sealing issues when facing complex and changing external environments, effectively improving the vehicle's safety, reliability, and service life.

[0071] In summary, the second sealing monitoring module and the first sealing monitoring module together constitute a comprehensive monitoring system for the sealing performance of the entire vehicle, providing the vehicle with more solid and reliable waterproof protection.

[0072] In some embodiments, the first sealing monitoring module includes a water-sensitive feature and outputs a signal when the first sealing monitoring module contacts liquid.

[0073] In some embodiments, the second sealing monitoring module includes a water-sensitive feature and outputs a signal when the second sealing monitoring module contacts liquid.

[0074] Water-sensitivity refers to the ability of a material or device to produce a detectable reaction or signal when exposed to liquid, particularly water. In this sealing device, both the first and second seal monitoring modules utilize water-sensitive materials or technologies, enabling rapid alarms in the event of seal failure or liquid intrusion.

[0075] If the sealing module fails to effectively prevent external liquid intrusion, the liquid will come into contact with the seal monitoring module. Due to its water-sensitive properties, upon contact with liquid, an internal mechanism is immediately triggered, outputting a recognizable signal. This signal may be electrical, optical, or in some other form, depending on the design of the monitoring module. The signal output terminal transmits the signal to the signal processing module via the first signal transmission module for further processing.

[0076] See also Figure 3 , Figure 3 This is a flow chart of steps S301-S303 of the sealing monitoring method provided in the embodiment of the present application, which will be combined with Figure 3 Steps S301-S303 are shown for explanation.

[0077] In step S301 , at least one liquid is determined based on the liquid intrusion condition.

[0078] In step S302, each of the at least one liquid is brought into contact with the first sealing module and the second sealing module respectively, and the first sealing monitoring module and the second sealing monitoring module are calibrated respectively according to the composition and hazard level of each liquid.

[0079] In step S303, the sealing performance of the entire vehicle is monitored based on the calibrated sealing device.

[0080] First, the method identifies at least one representative liquid by analyzing the liquid intrusion conditions that a vehicle may be exposed to (such as rainwater, car wash water, road water, chemical liquid leaks, etc.). These liquids represent potential threats that a vehicle may encounter under different environmental conditions and are therefore factors that must be considered in seal monitoring.

[0081] Next, each selected liquid is exposed to the first and second sealing modules, respectively. During this process, it is crucial to simulate actual operating conditions for liquid intrusion, including parameters such as pressure, flow rate, and temperature, to ensure calibration accuracy and reliability. Simultaneously, the first and second seal monitoring modules are calibrated based on the composition and hazard level of each liquid. The goal of calibration is to determine the sensitivity and response thresholds of the monitoring modules under different liquid intrusion conditions, enabling accurate identification and response to seal failures in actual monitoring.

[0082] Based on the calibrated sealing device, this method monitors the sealing performance of the entire vehicle in real time. When liquid intrusion triggers the water-sensitivity of the monitoring module, the module immediately outputs a signal, which is then transmitted to the signal processing module via the signal transmission module. The signal processing module then determines whether the sealing module has failed based on the received signal and uses this information to evaluate the sealing performance of the entire vehicle.

[0083] If a seal failure is detected, the signal processing module can issue an alarm, prompting the driver or maintenance personnel to take timely measures to deal with it. This can effectively prevent external liquids from further invading the passenger compartment and ensure the safety and comfort of passengers.

[0084] This seal monitoring method provides comprehensive and reliable assurance of the sealing performance of the CTB battery pack and its connection to the vehicle body by simulating liquid intrusion conditions, calibrating the monitoring module, and monitoring the vehicle's sealing in real time. This method not only improves vehicle safety and reliability, but also provides users with a more secure and worry-free driving experience.

[0085] In some embodiments, see Figure 4 , Figure 4 This is a flow chart of seal failure determination provided by an embodiment of the present application, such as Figure 4As shown, during the actual driving of the vehicle, there is a possibility that liquid from outside the vehicle may seep into the passenger compartment. At the same time, there is a possibility that liquid inside the passenger compartment may leak when liquid from outside the vehicle does not seep into the passenger compartment. There is also a possibility that liquid from outside the vehicle may seep into the passenger compartment and liquid inside the vehicle may leak occasionally. At this time, it is necessary to ensure that when liquid from outside the vehicle does not seep into the passenger compartment, the signal processing module reports the warning signal in a timely and accurate manner. However, when liquid from outside the vehicle does not seep into the passenger compartment, if liquid inside the passenger compartment leaks and contacts the sealing monitoring module, the warning signal cannot be falsely reported. In response to this requirement, the signal processing module determines the warning signal that needs to be reported and its level or reminder signal based on the presence, difference, and sequence of the signals output by the sealing monitoring module 1 and the sealing monitoring module 2.

[0086] When the sealing monitoring module 1 outputs a signal and the sealing monitoring module 2 does not output a signal, the signal processing module determines that there is a risk of liquid outside the vehicle entering the passenger compartment, and at this time the sealing module 1 has failed, the sealing module 2 has not failed and there is no liquid leakage in the vehicle at this time, and no liquid has actually entered the passenger compartment. The signal processing module reports a warning signal with a signal level of one, reminding the driver and passengers to arrange the vehicle as soon as possible, replace the sealing module 1, and clean the liquid to avoid damage to the sealing module 2 and the risk of liquid entering the passenger compartment.

[0087] When the sealing monitoring module 1 outputs a signal and the sealing monitoring module 2 also outputs a signal, if the sealing monitoring module 1 outputs a signal earlier than the sealing monitoring module 2 outputs a signal, there are two scenarios.

[0088] In scenario one, the signal output by sealing monitoring module 1 is consistent with the signal output by sealing monitoring module 2, indicating that they are in contact with the same liquid. At this time, it can be determined that sealing module 1 and sealing module 2 have failed due to the intrusion of liquid from outside the vehicle. Liquid has actually penetrated into the passenger compartment. The signal processing module reports a warning signal with a level three signal, reminding the driver and passengers to stop the car immediately, handle the vehicle immediately, replace sealing module 1 and sealing module 2, and clean the liquid.

[0089] In scenario two, the signal output by sealing monitoring module 1 is inconsistent with the signal output by sealing monitoring module 2. At this time, it can be determined that the sealing module 1 fails first due to the intrusion of liquid outside the vehicle, and the sealing monitoring module 1 reports a signal. Subsequently, the sealing monitoring module 2 outputs a signal due to the intrusion of liquid inside the passenger compartment. Although the passenger compartment has not actually been infiltrated by liquid outside the vehicle at this time, the sealing module 1 has failed, and the sealing module 2 is corroded by liquid outside the vehicle on both sides and liquid inside the vehicle, and there is a greater risk of failure. The signal processing module still maintains reporting a warning signal with a signal level of level two, reminding the driver and passengers to find a nearby service station to immediately place the vehicle, replace sealing module 1, and clean the liquid.

[0090] When the sealing monitoring module 1 outputs a signal and the sealing monitoring module 2 also outputs a signal, if the sealing monitoring module 1 outputs a signal later than the sealing monitoring module 2 outputs a signal, there are two scenarios.

[0091] In scenario one, the signal output by sealing monitoring module 1 is consistent with the signal output by sealing monitoring module 2. At this time, it can be determined that sealing monitoring module 2 reports the signal first, and then sealing module 2 fails due to the immersion of liquid in the passenger compartment. Although no external liquid has actually penetrated into the passenger compartment at this time, sealing module 2 has failed, and sealing module 1 may be corroded by liquid outside the vehicle on both sides and liquid inside the vehicle, and there is a greater risk of failure. At this time, the signal processing module must report an early warning signal with a signal level of level two, reminding the driver and passengers to find a nearby service station to immediately place the vehicle, replace sealing module 2, and clean the liquid.

[0092] In scenario two, the signal output by sealing monitoring module 1 is inconsistent with the signal output by sealing monitoring module 2. Affected by the liquid intrusion inside the vehicle, sealing monitoring module 2 reports a signal first, and then sealing module 1 fails due to the liquid intrusion outside the vehicle. Sealing monitoring module 1 reports a signal. Although no liquid from outside the vehicle has actually entered the passenger compartment at this time, sealing module 1 has failed. At this time, sealing module 2 is corroded by liquid outside the vehicle and liquid inside the vehicle on both sides, and there is a greater risk of failure. The signal processing module still maintains reporting a warning signal with a signal level of level two, reminding the driver and passengers to find a nearby service station to immediately place the vehicle, replace sealing module 1, and clean the liquid.

[0093] When the sealing monitoring module 1 does not output a signal and the sealing monitoring module 2 outputs a signal, it is determined that there is no risk of liquid outside the vehicle entering the passenger compartment, and the signal processing module does not report a warning signal. However, at this time, the sealing module 2 is at risk of failure due to liquid entering the passenger compartment. At this time, the signal processing module must report a reminder signal to remind the user to clean up the leaked liquid in the passenger compartment as soon as possible to ensure the reliability of the sealing module 2.

[0094] When the sealing monitoring module 1 does not output a signal and the sealing monitoring module 2 also does not output a signal, it is determined that there is no risk of liquid outside the vehicle entering the passenger compartment and there is no liquid leakage in the vehicle, and the signal processing module does not report a warning signal or a reminder signal.

[0095] Based on the calibration methods for seal monitoring modules 1 and 2 and the seal failure determination method described above, seal failures are monitored and failure modes determined in real time during vehicle operation. The signal processing module then generates warning and alert signals based on the determination results. If the vehicle is turned off at any time, monitoring ceases immediately. When the vehicle resumes operation, real-time seal failure monitoring and failure mode determination resume.

[0096] In summary, the embodiments of the present application have the following beneficial effects:

[0097] (1) Enhanced vehicle sealing performance: By designing a dual sealing structure of the first and second sealing modules, the sealing performance of the CTB battery pack and its connection with the vehicle body is significantly improved. This dual protection mechanism can effectively prevent external liquids from invading the passenger compartment, protecting passengers from water intrusion, while ensuring a dry environment inside the battery pack, preventing electrical failures and safety hazards.

[0098] (2) Real-time monitoring and early warning: The introduction of the first and second sealing monitoring modules, combined with water-sensitive characteristics, enables real-time monitoring of sealing performance. Once the seal fails, the monitoring module will immediately output a signal, and the signal processing module will respond quickly. This real-time monitoring and early warning mechanism can promptly detect and resolve potential sealing problems, preventing further liquid intrusion and causing greater losses.

[0099] (3) Accurate judgment and graded warning: The seal monitoring method not only focuses on the failure of the sealing module, but also accurately judges the cause of the seal failure by analyzing the liquid composition and intrusion sequence. Depending on the failure situation, the system can report different levels of warning signals, providing maintenance personnel with accurate fault information and guiding them to take appropriate countermeasures.

[0100] (4) Improve user experience: Through the intelligent monitoring and early warning system, users can timely understand the sealing status of the vehicle and avoid accidents caused by sealing problems.

[0101] (5) Improved vehicle safety and reliability: The dual-sealing structure and real-time monitoring and warning mechanism enhance vehicle safety and reliability. In adverse weather or complex road conditions, the vehicle maintains a good seal, ensuring the safety of passengers and the battery pack. Furthermore, by promptly identifying and resolving sealing issues, the vehicle's service life can be extended and maintenance costs reduced.

[0102] In summary, the present application example has significant beneficial effects in improving the sealing performance of the entire vehicle, ensuring the safety of passengers and battery packs, enhancing user experience, and improving vehicle safety and reliability.

[0103] Based on the same inventive concept, a sealing monitoring device corresponding to the sealing monitoring method in the first embodiment is also provided in the embodiment of the present application. Since the principle of solving the problem by the device in the embodiment of the present application is similar to that of the above-mentioned sealing monitoring method, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0104] like Figure 5 As shown, Figure 5 : is a schematic diagram of the structure of a sealing monitoring device 500 provided in an embodiment of the present application. Applied to a CTB battery pack, the upper cover of the CTB battery pack is a vehicle body floor, and the sealing monitoring device 500 includes:

[0105] A determination module 501 is configured to determine at least one liquid based on a liquid intrusion condition;

[0106] a calibration module 502 for contacting each of the at least one liquid with the first sealing module and the second sealing module, respectively, and calibrating the first sealing monitoring module and the second sealing monitoring module according to the composition and hazard level of each liquid;

[0107] The monitoring module 503 is used to monitor the sealing performance of the entire vehicle based on the calibrated sealing device.

[0108] Those skilled in the art should understand that Figure 5 The functions implemented by each unit in the sealing monitoring device 500 shown can be understood by referring to the relevant description of the aforementioned sealing monitoring method. Figure 5 The functions of the various units in the sealing monitoring device 500 shown can be implemented by a program running on a processor, or by a specific logic circuit.

[0109] In a possible implementation, the monitoring module 503 further includes:

[0110] When the first sealing module outputs a signal and the second sealing module does not output a signal, the signal processing module determines that the first sealing module has failed and the external liquid has not invaded the passenger compartment, and reports a first-level warning signal through the signal processing module;

[0111] When the first sealing module outputs a signal and the second sealing module also outputs a signal, if the liquid components contacted by the first sealing module and the second sealing module are the same or are within a preset error range, the signal processing module determines that both the first sealing module and the second sealing module have failed, and there is external liquid invading the passenger compartment, and reports a third-level warning signal through the signal processing module; if the liquid components contacted by the first sealing module and the second sealing module are different or are outside the preset error range, the signal processing module determines that the first sealing module has failed, the external liquid has not invading the passenger compartment, the second sealing module has not failed, and the liquid inside the vehicle has contacted the second sealing monitoring module, and reports a second-level warning signal through the signal processing module;

[0112] When the first sealing module outputs a signal and the second sealing module also outputs a signal, and the time when the first sealing monitoring module outputs a signal is later than the time when the second sealing monitoring module outputs a signal, if the liquid components contacted by the first sealing module and the second sealing module are the same or are within a preset error range, the signal processing module determines that the first sealing module has not failed, the second sealing module has failed, and the first sealing module is corroded by liquids inside and outside the vehicle at the same time, and reports a secondary warning signal through the signal processing module; if the liquid components contacted by the first sealing module and the second sealing module are different or are outside the preset error range, the signal processing module determines that the first sealing module has failed, the second sealing module has not failed, and the second sealing module is corroded by liquids inside and outside the vehicle at the same time, and reports a secondary warning signal through the signal processing module;

[0113] When the first sealing module does not output a signal and the second sealing module outputs a signal, the signal processing module determines that no liquid outside the vehicle has intruded into the passenger compartment, the signal processing module does not report a warning signal, and the signal processing module sends a reminder signal to remind passengers to clean up the leaked liquid in the passenger compartment;

[0114] When the first sealing module does not output a signal and the second sealing module also does not output a signal, the signal processing module determines that no liquid outside the vehicle has invaded the passenger compartment and there is no liquid leakage in the vehicle, and the signal processing module does not report a warning signal and does not send a reminder signal.

[0115] The above-mentioned sealing monitoring device has the following beneficial effects:

[0116] (1) Enhanced vehicle sealing performance: By designing a dual sealing structure of the first and second sealing modules, the sealing performance of the CTB battery pack and its connection with the vehicle body is significantly improved. This dual protection mechanism can effectively prevent external liquids from invading the passenger compartment, protecting passengers from water intrusion, while ensuring a dry environment inside the battery pack, preventing electrical failures and safety hazards.

[0117] (2) Real-time monitoring and early warning: The introduction of the first and second sealing monitoring modules, combined with water-sensitive characteristics, enables real-time monitoring of sealing performance. Once the seal fails, the monitoring module will immediately output a signal, and the signal processing module will respond quickly. This real-time monitoring and early warning mechanism can promptly detect and resolve potential sealing problems, preventing further liquid intrusion and causing greater losses.

[0118] (3) Accurate judgment and graded warning: The seal monitoring method not only focuses on the failure of the sealing module, but also accurately judges the cause of the seal failure by analyzing the liquid composition and intrusion sequence. Depending on the failure situation, the system can report different levels of warning signals, providing maintenance personnel with accurate fault information and guiding them to take appropriate countermeasures.

[0119] (4) Improve user experience: Through the intelligent monitoring and early warning system, users can timely understand the sealing status of the vehicle and avoid accidents caused by sealing problems. At the same time, the system can also send reminder signals in specific situations (such as liquid leakage in the car) to remind passengers to pay attention and take appropriate cleaning measures, thereby improving the user experience and satisfaction.
