Description

Technical Field

[0001] This application relates to the field of fuel cells, and in particular to a method, system and device for antifreeze control of hydrogen storage system in a fuel cell vehicle. Background Technology

[0002] Currently, fuel cell vehicles are widely used. Fuel cell vehicles use hydrogen as fuel. The hydrogen storage system is responsible for the storage and supply of hydrogen. Once the hydrogen storage system freezes, it will directly interfere with the start-up and operation of the fuel cell system, which will not only affect the normal use of the vehicle, but also reduce the user experience.

[0003] Existing hydrogen storage system antifreeze control technology employs a timed self-wake-up mechanism. During vehicle hibernation, the system is periodically woken up to briefly open the hydrogen valve and prevent freezing before returning to hibernation. However, this technology relies solely on fixed time intervals for wake-up, which are typically set empirically. In icy weather conditions, excessively long intervals may lead to infrequent wake-up and system freezing; conversely, excessively short intervals may result in unnecessary energy waste. Furthermore, in icy weather conditions, wake-up may not be necessary, and fixed-interval wake-ups would also cause unnecessary energy loss. Summary of the Invention

[0004] Therefore, it is necessary to provide a method, system, and device for antifreeze control of hydrogen storage system in fuel cell vehicles to address the above-mentioned technical problems. By adjusting the wake-up strategy of hydrogen storage system according to the environmental conditions of fuel cell vehicles, the impact of hydrogen storage system freezing on vehicle start-up and operation can be effectively reduced or even avoided. Furthermore, in environments where freezing is not easy, the energy loss from frequent opening of cylinder valves is reduced, thereby achieving more precise antifreeze control of hydrogen storage system.

[0009] During the wake-up of the hydrogen storage system, the cylinder valve of the hydrogen storage system is opened.

[0010] Furthermore, the environmental information includes altitude, ambient temperature, and ambient humidity. Determining the wake-up frequency and wake-up duration of the hydrogen storage system based on the environmental information includes:

[0011] Based on the altitude, ambient temperature, and ambient humidity, the corresponding wake-up frequency and wake-up duration are retrieved from the pre-stored environmental information and wake-up strategy correspondence table. Different environmental information corresponds to different wake-up strategies, and different wake-up strategies include corresponding wake-up frequencies and wake-up durations.

[0012] Furthermore, during the wake-up period of the hydrogen storage system, opening the cylinder valve of the hydrogen storage system includes:

[0013] During the wake-up of the hydrogen storage system, the cylinder valves of the hydrogen storage system are opened and closed at a predetermined frequency.

[0014] Furthermore, the determination of whether to execute the wake-up strategy for the hydrogen storage system includes:

[0015] Obtain the hydrogen concentration at the nozzle of the hydrogen storage system;

[0016] The decision on whether to execute the wake-up strategy for the hydrogen storage system is determined based on the hydrogen concentration.

[0017] Further, determining whether to execute the wake-up strategy for the hydrogen storage system based on the hydrogen concentration includes:

[0018] If the hydrogen concentration exceeds a preset value, the wake-up strategy will not be executed;

[0019] If the hydrogen concentration is within a safe range, then the decision on whether to execute the wake-up strategy is based on the trend of the hydrogen concentration change.

[0020] Further, determining whether to execute the wake-up strategy based on the changing trend of the hydrogen concentration includes:

[0021] If the hydrogen concentration continues to rise, the wake-up strategy will not be executed;

[0022] If the hydrogen concentration remains stable, a fault diagnosis is performed, and a wake-up strategy is executed based on the fault diagnosis result.

[0023] Furthermore, the step of determining whether to execute a wake-up strategy based on the fault diagnosis result includes:

[0024] If the fault level is the target level, the wake-up strategy is not executed; otherwise, a wake-up strategy correction coefficient is determined based on the fault level so that the wake-up frequency and wake-up duration of the hydrogen storage system can be corrected using the correction coefficient.

[0025] Furthermore, the hydrogen storage system is activated via an onboard remote communication terminal or via its own hydrogen storage controller.

[0026] Secondly, a hydrogen storage system antifreeze control system for a fuel cell vehicle is provided, including:

[0027] The judgment module is used to determine whether to execute the wake-up strategy of the hydrogen storage system;

[0028] The acquisition module is used to obtain environmental information when executing the wake-up strategy of the hydrogen storage system;

[0029] The determination module is used to determine the wake-up frequency and wake-up duration of the hydrogen storage system based on the environmental information.

[0030] A control module is used to open the cylinder valve of the hydrogen storage system during the wake-up process of the hydrogen storage system.

[0033] In the embodiments of this application, it is first determined whether to execute the hydrogen storage system wake-up strategy. If so, environmental information is obtained first, and then the wake-up frequency and duration of the hydrogen storage system are determined based on the environmental information. Finally, during the wake-up period of the hydrogen storage system, the cylinder valve of the hydrogen storage system is opened. Therefore, compared with the fixed time interval wake-up technology, adjusting the wake-up strategy of the hydrogen storage system according to the environmental conditions of the fuel cell vehicle can effectively reduce or even avoid the impact of hydrogen storage system icing on vehicle start-up and operation. Furthermore, in environments where icing is not likely, it reduces the energy loss from frequent cylinder valve opening, thereby achieving more precise antifreeze control of the hydrogen storage system.

[0041] The present application will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0042] It should be noted that, unless otherwise specified, the embodiments and features of the embodiments in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] The following describes in detail, with reference to the accompanying drawings, a method, system, and device for preventing freezing of the hydrogen storage system of a fuel cell vehicle according to embodiments of this application.

[0044] Figure 1 This is a flowchart of an antifreeze control method for a hydrogen storage system of a fuel cell vehicle according to an embodiment of this application. Figure 1 As shown, the antifreeze control method for the hydrogen storage system of a fuel cell vehicle according to an embodiment of this application includes the following steps:

[0045] S101: Determine whether to execute the wake-up strategy for the hydrogen storage system.

[0046] In one embodiment of this application, determining whether to execute the wake-up strategy of the hydrogen storage system includes: obtaining the hydrogen concentration at the outlet of the hydrogen storage system; and determining whether to execute the wake-up strategy of the hydrogen storage system based on the hydrogen concentration.

[0047] In a specific example, the hydrogen concentration can be collected by the hydrogen storage controller of the hydrogen storage system and provided to the on-board telematics box (TBOX) for judgment.

[0048] TBOX enables data interaction between the vehicle and the outside world by connecting the vehicle's Controller Area Network (CAN) bus and the cloud platform. TBOX can upload information such as the opening status of the cylinder valve, the temperature and pressure of the cylinder opening, and the hydrogen concentration provided by the hydrogen storage controller to the big data platform in real time. It can also remotely control the vehicle, such as remotely waking up the hydrogen storage controller to enable the hydrogen storage controller to open and close the cylinder valve of the hydrogen storage system.

[0049] In the above description, determining whether to execute the wake-up strategy of the hydrogen storage system based on the hydrogen concentration includes: if the hydrogen concentration exceeds a preset value, then the wake-up strategy is not executed.

[0050] The preset value is a pre-defined threshold for hydrogen concentration in the hydrogen storage system. For fuel cell vehicles, excessively high hydrogen concentrations in the storage system may pose a risk of deflagration; therefore, a safe threshold range needs to be set based on actual conditions, combined with... Figure 2 As shown, if the hydrogen concentration exceeds a preset value, the wake-up strategy is not executed, and the information about the excessively high hydrogen concentration is reported to the big data platform. The big data platform then notifies the user and operator via a mobile app. If the concentration does not exceed the preset value, the process continues. It should be noted that the preset value can be set according to actual conditions.

[0051] In the above example, if the hydrogen concentration is within a safe range, the decision to execute the wake-up strategy can be based on the trend of the hydrogen concentration. That is, when the hydrogen concentration is within a safe range, the decision to execute the wake-up strategy can be based on the trend of the hydrogen concentration. For example, if the hydrogen concentration continues to rise, the wake-up strategy is not executed; if the hydrogen concentration remains stable, a fault diagnosis is performed, and the decision to execute the wake-up strategy is based on the fault diagnosis result.

[0052] Specifically, combined Figure 2 As shown, once it is determined that the hydrogen concentration is below a preset value, meaning the hydrogen concentration is temporarily within a safe range, the system continues to monitor changes in hydrogen concentration. If the hydrogen concentration continues to rise, it is considered to be in a risky state, the wake-up strategy is not executed, and the information about the continuously rising hydrogen concentration is reported to the big data platform. The big data platform then notifies the user and operator via a mobile app. If the hydrogen concentration remains stable within a certain time threshold, fault diagnosis of the fuel cell vehicle begins, and the decision to execute the wake-up strategy is based on the fault diagnosis results. It should be noted that the time threshold can be set according to actual conditions.

[0053] The step of determining whether to execute a wake-up strategy based on the fault assessment result includes: if the fault level is the target level, then the wake-up strategy is not executed; otherwise, a wake-up strategy correction coefficient is determined based on the fault level, so that after determining the wake-up frequency and wake-up duration of the hydrogen storage system, the wake-up frequency and wake-up duration are corrected using the correction coefficient.

[0054] In the example above, faults are divided into four levels, where level 0 represents no fault and level 3 represents the highest level fault. When a vehicle experiences a level 3 fault, the wake-up policy is not executed, and the information about the level 3 fault is reported to the big data platform. The big data platform then notifies the user and the operator via a mobile app. When a vehicle experiences a level 0 / 1 / 2 fault, the wake-up policy corresponding to the fault level is executed.

[0055] Specifically, when the fault level is 0, i.e., no fault, the wake-up frequency is set to Δt hours / time, and the wake-up time is set to t minutes. When a level 1 or level 2 fault occurs, two correction coefficients α and β are set, so that in the same scenario, the wake-up frequency is α × Δt hours / time, and the wake-up time is β × t minutes. It should be noted that the values ​​of correction coefficients α and β are different for level 1 and level 2 faults, and the values ​​of correction coefficients α and β can be adjusted according to the actual situation for different scenarios.

[0056] S102: When executing the wake-up strategy of the hydrogen storage system, obtain environmental information.

[0057] In one embodiment of this application, the environmental information includes, but is not limited to, altitude, ambient temperature, and ambient humidity. This environmental information can be provided to TBOX by a big data platform.

[0058] Among these factors, ambient temperature directly affects the probability of hydrogen storage system freezing; the lower the ambient temperature, the easier it is for the hydrogen storage system to freeze. Secondly, the higher the ambient humidity, the easier it is for water vapor in the air to penetrate into the hydrogen storage system. If the ambient temperature is low at this time, it will lead to an increase in the probability of the hydrogen storage system freezing. In addition, the air pressure is lower at high altitudes. Under the same environmental conditions, the lower the air pressure, the easier it is for water vapor to condense, which in turn increases the probability of hydrogen storage system freezing.

[0059] S103: Based on the environmental information, determine the wake-up frequency and wake-up duration of the hydrogen storage system.

[0060] In one embodiment of this application, determining the wake-up frequency and wake-up duration of the hydrogen storage system based on the environmental information includes: querying the corresponding wake-up frequency and wake-up duration from a pre-stored table of environmental information and wake-up strategies based on the altitude, ambient temperature, and ambient humidity, wherein different environmental information corresponds to different wake-up strategies, and different wake-up strategies include corresponding wake-up frequencies and wake-up durations.

[0061] In the above example, different wake-up frequencies and wake-up durations are set according to different environmental information. For example, when the vehicle is located in the Yangtze River Delta region with low altitude and high humidity, and in the winter when the temperature is low, the wake-up strategy of the hydrogen storage system can be set to wake up every 2 hours from 3 am to 7 am, with a wake-up frequency of 2 hours / time and a wake-up duration of 5 minutes.

[0062] Understandably, the minimum values ​​for the wake-up frequency and wake-up duration of the hydrogen storage system can be zero. For example, when the vehicle is in a region like Guangdong where icing is not common, or during the hot summer months, the hydrogen storage system generally will not freeze, so the wake-up frequency and wake-up duration of the hydrogen storage system can be set to zero.

[0063] It should be noted that the above wake-up strategy is only an example, and adjustments and optimizations can be made according to actual circumstances in other examples.

[0064] In practical applications, wake-up strategies corresponding to different altitudes and humidity levels can be pre-defined and stored in a strategy table. Then, after obtaining the current environmental information, the strategy table can be queried to obtain the wake-up frequency and wake-up duration of the corresponding hydrogen storage system.

[0065] S104: During the wake-up of the hydrogen storage system, open the bottle valve of the hydrogen storage system.

[0066] In one embodiment of this application, opening the cylinder valve of the hydrogen storage system during the wake-up period includes: switching the cylinder valve of the hydrogen storage system at a predetermined frequency during the wake-up period. This prevents excessively high hydrogen concentrations in the hydrogen storage system and also achieves effective de-icing, thus realizing precise antifreeze control.

[0067] In one embodiment of this application, the hydrogen storage system is activated via an onboard remote communication terminal or via its own hydrogen storage controller.

[0068] Among them, the vehicle-mounted remote communication terminal wake-up method wakes up the hydrogen storage controller remotely through TBOX, so that the hydrogen storage controller opens and closes the cylinder valve of the hydrogen storage system according to the corresponding wake-up frequency and within the corresponding wake-up duration.

[0069] Another method for waking up the hydrogen storage system is through its own hydrogen storage controller. When the preset wake-up time is reached, the hydrogen storage controller first performs self-wake-up, and then obtains the current vehicle altitude, ambient temperature and ambient humidity information from the TBOX. Based on this information, different wake-up strategies are executed, and the cylinder valve of the hydrogen storage system is opened and closed within the corresponding wake-up time according to the corresponding wake-up frequency.

[0070] According to the antifreeze control method for the hydrogen storage system of a fuel cell vehicle in this application embodiment, the method first determines whether to execute the wake-up strategy of the hydrogen storage system. If the wake-up strategy is executed, environmental information is first obtained, and then the wake-up frequency and duration of the hydrogen storage system are determined based on the environmental information. Finally, during the wake-up period of the hydrogen storage system, the cylinder valve of the hydrogen storage system is opened. Therefore, compared with the fixed time interval wake-up technology, adjusting the wake-up strategy of the hydrogen storage system according to the environmental conditions of the fuel cell vehicle can effectively reduce or even avoid the impact of hydrogen storage system icing on vehicle start-up and operation. Furthermore, in environments where icing is not likely, it reduces the energy loss from frequent cylinder valve opening, thereby achieving more precise antifreeze control of the hydrogen storage system.

[0071] Figure 5 This is a structural block diagram of an antifreeze control system for a hydrogen storage system of a fuel cell vehicle according to an embodiment of this application. Figure 5 As shown, the antifreeze control system for the hydrogen storage system of a fuel cell vehicle according to an embodiment of this application includes: a judgment module 510, an acquisition module 520, a determination module 530, and a control module 540, wherein:

[0072] The judgment module 510 is used to determine whether to execute the wake-up strategy of the hydrogen storage system;

[0073] The acquisition module 520 is used to obtain environmental information when executing the wake-up strategy of the hydrogen storage system;

[0074] The determination module 530 is used to determine the wake-up frequency and wake-up duration of the hydrogen storage system based on the environmental information.

[0075] The control module 540 is used to open the cylinder valve of the hydrogen storage system during the wake-up period of the hydrogen storage system.

[0076] According to the antifreeze control system of the hydrogen storage system of the fuel cell vehicle in this application embodiment, the system first determines whether to execute the wake-up strategy of the hydrogen storage system. If the wake-up strategy is executed, environmental information is first obtained, and then the wake-up frequency and duration of the hydrogen storage system are determined based on the environmental information. Finally, during the wake-up period of the hydrogen storage system, the cylinder valve of the hydrogen storage system is opened. Therefore, compared with the fixed time interval wake-up technology, adjusting the wake-up strategy of the hydrogen storage system according to the environmental conditions of the fuel cell vehicle can effectively reduce or even avoid the impact of hydrogen storage system icing on vehicle start-up and operation. Furthermore, in environments where icing is not likely, it reduces the energy loss from frequent cylinder valve opening, thereby achieving more precise antifreeze control of the hydrogen storage system.
