[0002] As energy resources become increasingly scarce, hydrogen energy, a clean energy source, is gaining increasing attention.

To prevent this, all types of hydrogen fuel cell vehicles are currently equipped with hydrogen leak monitoring systems.

[0054] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0056] In a first aspect, an embodiment of the present application provides a hydrogen leakage monitoring method.

[0057] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the hydrogen leakage monitoring method of this application. Figure 1 As shown, the hydrogen leakage monitoring method includes:

[0058] Step S10: When the vehicle is not started and the real-time solar operating parameter is greater than or equal to the operating parameter threshold, the solar power generation module is controlled to be in a connected state with the battery so that the solar power generation module charges the battery.

[0059] For demonstration purposes, this embodiment will construct a hydrogen leakage monitoring system by adding a solar power generation device and related hydrogen leakage monitoring equipment to a fuel cell vehicle to achieve hydrogen leakage monitoring. That is, during the vehicle parking phase, solar energy is used to realize the energy supply of the vehicle hydrogen leakage monitoring system to realize hydrogen leakage monitoring and alarm during the fuel cell parking phase, thereby improving the safety of fuel cell vehicle use.

[0060] For details, see Figure 2As shown, the hydrogen leak monitoring system includes a hydrogen leak monitoring controller, a vehicle controller, an audible and visual alarm module, a battery charge sensor, a light intensity sensor or a power generation monitoring module, a hydrogen concentration detection module, a solar power generation module including a controller, a battery, an onboard charging system, and a remote monitoring terminal. The battery can be the main battery on a fuel cell vehicle. The hydrogen leak monitoring controller is used to receive and control signals for the entire hydrogen leak monitoring system. It can receive signals from the hydrogen concentration detection module, the battery charge, and light intensity, and simultaneously issue control signals such as switch closures and alarms. It can also communicate with the vehicle controller and the solar power generation module. The solar power generation module is a solar power generation system added to the vehicle and can be placed in a location such as the roof. This module includes a controller for communicating with the hydrogen leak monitoring controller. If the hydrogen leak monitoring controller goes dormant due to battery power supply, the solar power generation module can wake up the hydrogen leak monitoring controller when the light intensity or power generation is strong and the solar power generation module itself is not faulty.

[0061] The hydrogen concentration detection module is a variety of hydrogen concentration sensors arranged on the vehicle, which can detect hydrogen leakage in relevant hydrogen-related parts of the vehicle and hydrogen leakage around the vehicle and send it to the hydrogen leakage monitoring controller; the sound and light alarm module is used for sound and light alarm when hydrogen leakage occurs in the vehicle. This module is controlled by the hydrogen leakage monitoring controller; in addition, the vehicle is also equipped with a light intensity sensor to monitor the light intensity and judge the power generation performance of the solar power generation device, or a power generation power monitoring module is arranged to monitor the power generation power of the solar power generation module and judge the power generation performance of the solar power generation device; the on-board charging system is used to power the vehicle after starting and charge the battery; when the vehicle is shut down and cannot be used, the remote monitoring terminal is used to receive the status parameters and alarm signals of the hydrogen leakage monitoring controller in real time to realize the remote monitoring function.

[0062] It should be noted that the operating parameter threshold refers to the minimum parameter value corresponding to the normal operation of the solar power generation module. Its specific value can be determined according to actual needs and is not limited here. Among them, the real-time solar operating parameter can preferably be the real-time light intensity or the real-time power generation power of the solar power generation module; if the real-time solar operating parameter is the real-time light intensity, the operating parameter threshold is the light intensity threshold, and if the real-time solar operating parameter is the real-time power generation power, the operating parameter threshold is the power generation power threshold. Since the implementation principles and methods of the two operating parameters are similar, for the sake of simplicity of description, the following embodiments will take the real-time solar operating parameter being the real-time light intensity as an example to explain the principle of hydrogen leakage monitoring.

[0063] See also Figure 3As shown, when the hydrogen leakage monitoring controller detects that the vehicle is in an unstarted state, the hydrogen leakage monitoring controller will obtain the real-time light intensity from the light intensity sensor to judge the light intensity, that is, to judge whether the real-time light intensity is greater than or equal to the light intensity threshold B1; if the real-time light intensity ≥ B1, it means that the light intensity at this time can meet the minimum light intensity corresponding to the normal operation of the solar power generation module, that is, the light intensity outside the vehicle is strong at this time, and the solar power generation module can work normally, then the hydrogen leakage monitoring controller will control the mode switching switch Z1 to be in the closed state, so that the solar power generation module and the battery are in a connected state, and then start the solar power generation module to generate electricity to charge the battery.

[0064] It should be noted that when the solar power generation module and the battery are in a connected state, the solar power generation module can also be monitored for faults. If a fault is found in the solar power generation module, that is, the battery cannot be charged, an audible and visual alarm will be issued to remind the user to take timely measures to resolve the fault problem in the solar power generation module.

[0065] Step S20: When the real-time power level of the battery is greater than a first power threshold, the battery is controlled to continuously supply power to continuously monitor hydrogen leakage.

[0066] For example, it can be understood that for fuel cell vehicles, the battery is usually used to power the vehicle's startup. Therefore, the minimum power required to ensure the vehicle can start normally can be used as the first power threshold Q1. Of course, its specific value can also be determined according to actual needs and is not limited here.

[0067] In this embodiment, while the solar power generation module is charging the battery, the hydrogen leakage monitoring controller will determine the real-time battery power level, that is, whether the real-time power level is greater than the first power threshold Q1; if the real-time power level is greater than Q1, it means that the real-time power level at this time can meet the minimum power level corresponding to the normal start of the vehicle. In this way, the battery is controlled to continuously supply power to the hydrogen leakage monitoring system, so that hydrogen leakage can be continuously monitored in the parked state, thereby providing conditions for timely detection of hydrogen leakage problems. In addition, see Figure 3 As shown, during the continuous monitoring of hydrogen leakage, if the hydrogen concentration detection module detects hydrogen leakage, the sound and light alarm module will sound an audible and visual alarm to remind the user to take measures to solve the hydrogen leakage problem, thereby avoiding safety accidents caused by hydrogen leakage.

[0068] In this embodiment, the solar power generation module and the battery are controlled to be in a connected state so that the solar power generation module can charge the battery when the vehicle is in a stopped state, and when the real-time power level of the battery is greater than a first power threshold, the battery is controlled to continue to supply power, so as to achieve continuous monitoring of hydrogen leakage in the stopped state, and thus timely discover hydrogen leakage problems, thereby effectively avoiding safety accidents caused by hydrogen leakage.

[0069] Furthermore, in one embodiment, after the step of controlling the solar power generation module to be in a connected state with the battery so that the solar power generation module charges the battery, the method further includes:

[0070] When the real-time power level of the storage battery is less than or equal to a first power threshold, the storage battery is controlled to supply power intermittently to perform intermittent monitoring of hydrogen leakage.

[0071] For example, in this embodiment, during the process of the solar power generation module charging the battery, if the hydrogen leakage monitoring controller detects that the real-time power is ≤ Q1, it means that the battery power is insufficient, that is, it cannot meet the normal starting requirements of the vehicle; at this time, in order to save battery power, the battery will be controlled to intermittently power the hydrogen leakage monitoring system, so that the hydrogen leakage monitoring system will be intermittently dormant, thereby realizing intermittent monitoring of hydrogen leakage. For example, the hydrogen leakage monitoring system first performs hydrogen leakage monitoring for 10 minutes. If no hydrogen leakage problem is found, it enters the dormant state; then, after 30 minutes, it repeats the hydrogen leakage monitoring for 10 minutes. If no hydrogen leakage problem is found, it continues to enter the dormant state, and repeats this process until it detects that the real-time power is greater than Q1 or the vehicle is in the starting state, at which time the intermittent dormant mode will be ended. It is understandable that the intermittent dormant time can be dynamically adjusted according to the detected hydrogen leakage situation.

[0072] Furthermore, in one embodiment, before the step of controlling the battery to continuously supply power, the method further includes:

[0073] Determining whether the real-time power level of the battery is less than a second power threshold;

[0074] If so, executing the step of controlling the battery to continuously supply power;

[0075] If not, the solar power generation module is controlled to be disconnected from the battery, and the step of controlling the battery to continuously supply power is performed.

[0076] For example, it should be understood that overcharging a battery can shorten its service life. Therefore, in this embodiment, to prevent battery overcharging, a second power threshold Q2 is set. This second power threshold Q2 refers to the maximum allowable charge level of the battery. The specific value of this second power threshold Q2 can be determined based on actual needs and is not limited here.

[0077] Therefore, when it is determined that the real-time battery charge is greater than Q1, a further determination is made as to whether the real-time charge is less than Q2. If so, this indicates that the battery charge has not reached the maximum allowable charge, meaning that an overcharge has not occurred. The solar power generation module is then controlled to continue charging the battery, and the battery is controlled to continue supplying power to the hydrogen leakage monitoring system. If not, this indicates that the battery charge has reached the maximum allowable charge, meaning that an overcharge has occurred. At this point, the control mode switch Z1 is turned off, disconnecting the solar power generation module from the battery and stopping the solar power generation module. This prevents the solar power generation module from continuing to charge the battery, and the battery is controlled to continue supplying power to the hydrogen leakage monitoring system.

[0078] Furthermore, in one embodiment, when the vehicle is in an unstarted state and the real-time solar operating parameter is less than the operating parameter threshold, it is determined whether the real-time power level of the battery is greater than the first power threshold;

[0079] If yes, controlling the battery to intermittently supply power to intermittently monitor hydrogen leakage;

[0080] If not, the control enters the sleep state.

[0081] For example, see Figure 3 As shown, when the hydrogen leakage monitoring controller detects that the vehicle is not started and the real-time light intensity is less than B1, it indicates that the light intensity is insufficient, so that the solar power generation module cannot work normally. At this time, it is necessary to further determine whether the real-time battery power is greater than Q1. If the real-time power is greater than Q1, it means that the battery has excess power to power the hydrogen leakage monitoring while ensuring that the vehicle can start normally. However, in order to avoid excessive power consumption of hydrogen leakage monitoring, that is, to save battery power, the battery will be controlled to intermittently power the hydrogen leakage monitoring system, so that the hydrogen leakage monitoring system will be intermittently dormant, thereby achieving intermittent monitoring of hydrogen leakage. It can be seen that by putting the system into intermittent dormancy, it can ensure that the hydrogen leakage monitoring system can monitor while also ensuring that the vehicle battery has sufficient power for normal vehicle starting.

[0082] If the real-time power level is ≤ Q1, it means that the battery power is insufficient, which means it cannot meet the normal starting requirements of the vehicle, and the solar power generation module cannot charge the battery. At this time, the remote monitoring module can issue a low battery alarm to remind the vehicle to charge or move the vehicle to a well-lit place, and put the hydrogen leakage monitoring system into sleep mode to prevent the battery power from being further consumed.

[0083] Furthermore, in one embodiment, when the vehicle is in a starting state, the solar power generation module is controlled to be disconnected from the battery so that the on-board charging system charges the battery;

[0084] The battery is controlled to continuously supply power to continuously monitor hydrogen leakage.

[0085] For example, see Figure 3 As shown, the hydrogen leak monitoring controller communicates with the vehicle controller to monitor whether the vehicle is in the start-up state. If the vehicle is in the start-up state, Z1 is disconnected, stopping the solar power generation module. At this time, the hydrogen leak monitoring system is powered by the vehicle, that is, the battery is charged through the onboard charging system, so that the battery continuously powers the hydrogen leak monitoring system, thereby putting the hydrogen leak monitoring system into continuous monitoring mode, thereby monitoring hydrogen leaks in various parts of the vehicle and the surrounding area in real time. If a hydrogen leak occurs, not only will an audible and visual alarm be issued in a timely manner, but the hydrogen leak information will also be transmitted to the vehicle controller for relevant processing by the vehicle.

[0086] Furthermore, in one embodiment, if a wake-up signal is received while the vehicle is in a dormant state, it is determined whether the wake-up signal is a first wake-up signal or a second wake-up signal, wherein the first wake-up signal is when a real-time solar operating parameter is greater than or equal to an operating parameter threshold, and the second wake-up signal is when the vehicle is in a start-up state;

[0087] When the wake-up signal is the first wake-up signal, executing the step of controlling the solar power generation module and the battery to be in a connected state;

[0088] When the wake-up signal is the second wake-up signal, the step of controlling the solar power generation module and the battery to be in a disconnected state is performed.

[0089] For example, in this embodiment, when the system is in a dormant state, the system can exit the dormant mode through a wake-up signal. Figure 3As shown, when a wake-up signal is received, it is determined whether the wake-up signal is that the light intensity is greater than or equal to B1 or the vehicle is in the starting state; if the wake-up signal is that the light intensity is ≥ B1, the solar power generation module will automatically wake up the hydrogen leakage monitoring controller. At this time, the hydrogen leakage monitoring controller will control the solar power generation module and the battery to be in a connected state, so that the solar power generation module can charge the battery; if the wake-up signal is that the vehicle is in the starting state, the vehicle controller will automatically wake up the hydrogen leakage monitoring controller. At this time, the hydrogen leakage controller will control the solar power generation module and the battery to be in a disconnected state, so that the battery can be charged through the on-board charging system.

[0090] In summary, this embodiment, by adding a solar power generation module to a vehicle to form a hydrogen leakage monitoring system, enables hydrogen leakage monitoring during the vehicle's downtime, effectively improving the timeliness of hydrogen leakage monitoring during the vehicle's downtime and enhancing the safety of fuel cell vehicles. Furthermore, it also provides remote monitoring capabilities, enabling remote, real-time monitoring of the vehicle. It is understood that this embodiment is applicable to various types of fuel cell vehicles.

[0091] In a second aspect, an embodiment of the present application also provides a hydrogen leakage monitoring system.

[0092] In one embodiment, referring to Figure 2 , Figure 2 This is a functional module diagram of an embodiment of the hydrogen leakage monitoring system of this application. Figure 2 As shown, the hydrogen leakage monitoring system includes a hydrogen leakage monitoring controller, which is used to:

[0093] When the vehicle is in an unstarted state and the real-time light intensity is greater than or equal to the light intensity threshold, controlling the solar power generation module and the battery to be in a connected state so that the solar power generation module charges the battery;

[0094] When the real-time power level of the battery is greater than a first power threshold, the battery is controlled to continuously supply power to continuously monitor hydrogen leakage.

[0095] For details, see Figure 2As shown, the hydrogen leak monitoring system includes not only a hydrogen leak monitoring controller, but also a vehicle controller, an audio and visual alarm module, a battery charge sensor, a light intensity sensor or a power generation monitoring module, a hydrogen concentration detection module, a solar power generation module including a controller, a battery, an onboard charging system, and a remote monitoring terminal.

It can receive signals from the hydrogen concentration detection module, the battery charge, and light intensity, and simultaneously issue control signals such as switch closures and alarms. It can also communicate with the vehicle controller and the solar power generation module. The solar power generation module is a solar power generation system added to the vehicle and can be placed in a location such as the roof. This module includes a controller for communicating with the hydrogen leak monitoring controller. If the hydrogen leak monitoring controller goes dormant due to battery power, the solar power generation module can wake it up when the light intensity or power generation is strong and the solar power generation module itself is not faulty.

[0096] The hydrogen concentration detection module is a variety of hydrogen concentration sensors arranged on the vehicle, which can detect hydrogen leakage in relevant hydrogen-related parts of the vehicle and hydrogen leakage around the vehicle and send it to the hydrogen leakage monitoring controller; the sound and light alarm module is used for sound and light alarm when hydrogen leakage occurs in the vehicle. This module is controlled by the hydrogen leakage monitoring controller; in addition, the vehicle is also equipped with a light intensity sensor to monitor the light intensity and judge the power generation performance of the solar power generation device, or a power generation power monitoring module is arranged to monitor the power generation power of the solar power generation module and judge the power generation performance of the solar power generation device; the on-board charging system is used to power the vehicle after starting and charge the battery; when the vehicle is shut down and cannot be used, the remote monitoring terminal is used to receive the status parameters and alarm signals of the hydrogen leakage monitoring controller in real time to realize the remote monitoring function.
