[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 8 The water temperature control device, method, electronic device and vehicle of the hydrogen and oxygen fuel cell provided in the embodiments of the present application are described in detail.

[0036] Please refer to Figure 1 , which is a structural block diagram of a hydrogen and oxygen fuel cell water temperature control device provided in an embodiment of the present application. The hydrogen and oxygen fuel cell water temperature control device 100 includes an acquisition module 101, a table lookup module 102 and a control module 103 that are interconnected. Among them, the acquisition module 101 can obtain the ambient temperature of the vehicle collected by the ambient temperature sensor and the current output value collected by the current sensor. The ambient temperature sensor can be installed at the bottom of the vehicle cab to detect the real atmospheric temperature. That is to say, the ambient temperature sensor is far away from the radiator to avoid interference from the hot air blown out by the radiator, ensuring that the data is true and reliable, and the current sensor can be installed at the output end of the hydrogen and oxygen fuel cell to detect and feedback the current output value of the stack under different load conditions in real time, thereby enhancing the immediate response of the control. The table lookup module 102 can search for the fan basic opening value corresponding to the ambient temperature and current output value of the vehicle in a two-dimensional parameter table containing the ambient temperature and the output current according to the ambient temperature and the current output value of the vehicle, and transmit the fan basic opening value to the control module 103. The two-dimensional parameter table can be as follows Figure 2Furthermore, the control module 103 can adjust the cooling system of the hydrogen-oxygen fuel cell based on the basic fan opening value to control the operating temperature of the hydrogen-oxygen fuel cell.

[0037] It should be noted that in the early stage of establishing the two-dimensional parameter table, the embodiment of the present application can perform preliminary calibration on the two-dimensional parameter table through laboratory tests and preliminary vehicle road tests, and reasonably fill in the uncalibrated areas to form preliminary control parameters. For example, during vehicle development, calibration tests under strict control conditions in the laboratory are performed to obtain the basic fan opening values ​​corresponding to the ambient temperature and output current of a series of key points as the initial filling data for the lookup table. For the lookup table areas that are not directly calibrated, mathematical interpolation, trend extrapolation or other statistical methods are used to fill in the remaining blanks based on the existing calibration point data to ensure that the lookup table can provide preliminary fan opening reference values ​​under any given combination of ambient temperature and output current.

[0038] For example, Figure 3As shown, in the embodiment of the present application, the table lookup module 102 may include an identification unit 1021 and an updating unit 1022. Among them, the identification unit 1021 can detect whether the ambient temperature of the vehicle and the change in the current output value meet the preset steady-state operating conditions, and when the change meets the preset steady-state operating conditions, the current fan opening value is obtained through the control module 103, and the coolant outlet temperature collected by the coolant temperature sensor can be obtained through the acquisition module 101, and the change in the coolant outlet temperature is detected. Whether the preset steady-state operating conditions are met, the coolant temperature sensor can be installed in the cooling circuit of the hydrogen-oxygen fuel cell, especially at the outlet of the coolant, thereby continuously monitoring the temperature state of the coolant to ensure that any subtle temperature fluctuations are captured in time, which is crucial for accurately controlling the fan opening and maintaining the ideal operating temperature of the fuel cell. For example, the preset steady-state operating conditions include but are not limited to ① the change amplitude of the ambient temperature within the set time window does not exceed a certain threshold, such as the ambient temperature change within 10 minutes is ≤±2°C, ② the battery output current remains stable without obvious load changes, such as the fuel cell operating condition does not change load within 10 minutes, and the battery output current fluctuation amplitude is ≤±2A, ③ the coolant outlet temperature control deviation (i.e., the difference between the actual outlet temperature and the target outlet temperature) remains within a certain deviation range, such as the coolant outlet temperature control deviation is ≤±1°C within 10 minutes, ④ the thermostat is continuously in a large cycle working state to eliminate the impact caused by the switching of large and small cycles. The large cycle means that when the temperature of the cooling water is higher than 80°C, the main valve of the thermostat is fully opened, the side valve is fully closed, and the cooling water all flows into the radiator, and the cooling intensity is high, such as the thermostat is always in a large cycle working state within 10 minutes, ⑤ the change rate of the coolant outlet temperature is lower than the preset threshold, and the temperature regulation is determined to be smooth and fluctuating, such as the change rate of the coolant outlet temperature within 10 minutes is ≤0.5°C / min, etc. If all the above steady-state operating conditions are met, the vehicle is considered to be running stably, and the vehicle's ambient temperature, current output value and current fan opening are recorded. If any of the conditions are not met, the vehicle is considered to be running unstably, and the vehicle's ambient temperature, current output value and current fan opening are not recorded.

[0039] The update unit 1022 can automatically and instantly update the two-dimensional parameter table according to the ambient temperature of the vehicle, the current output value and the current opening value of the fan, that is, write the new data point into the table cell corresponding to the corresponding ambient temperature and output current, and realize the dynamic optimization of the basic opening parameters of the fan. This self-learning process does not require manual intervention, ensuring the continuous evolution of the control strategy and accurately matching the actual operation needs. For example, the table lookup is usually evenly divided according to the intervals of temperature and current, and the new data point will fall in a specific temperature and current coordinate grid. At this time, the update unit 1022 can also determine the target position of the ambient temperature of the vehicle, the current output value and the current opening value of the fan in the two-dimensional parameter table, and then use the interpolation method to correct the data in the neighborhood of the target position. The interpolation method includes but is not limited to linear interpolation and polynomial interpolation. Further, for the newly recorded data point, if the table lookup items around it are null values ​​or need to be optimized, the linear interpolation method can be used to estimate the fan opening value in the middle area based on the point and its nearest known neighboring points (which may be preset or previously learned), and the adjacent vacant cells are filled along the slope by calculating the slope, thereby ensuring the continuity of the data. For situations where a smoother transition with higher precision is required, quadratic or higher-order polynomial interpolation can be used to form a smooth surface by fitting the new data points and their surrounding known points, thereby updating the adjacent data to ensure that the transition is natural and fits the actual operating mode.

[0040] For example Figure 4 As shown, in the embodiment of the present application, the table lookup module 102 may also include a switching unit 1023, which can perform data verification on the two-dimensional parameter table. If the verification result is abnormal, the current two-dimensional parameter table is switched to the backup parameter table, which is the two-dimensional parameter table of the initial operation of the hydrogen-oxygen fuel cell, that is, automatically switching to the safety mode to maintain the basic water temperature control function and ensure the safety of vehicle operation. For example, the data verification mechanism includes the relationship from left to right between the fan basic opening value of each row in the two-dimensional parameter table, that is, the right value is not less than the left value, the relationship from top to bottom between the fan basic opening value of each column in the two-dimensional parameter table, that is, the next row value is not less than the previous row value, and the fan basic opening value range is 0 to 100, unit %, etc.

[0041] Another example Figure 5As shown, in the embodiment of the present application, the table lookup module 102 may also include a storage unit 1024, which can store and export a two-dimensional parameter table. For example, the storage unit 1024 may be a ferroelectric random access memory (FRAM). The advantage of such a setting is that it has the advantages of fast reading and writing, high durability and non-volatility, and can ensure that the system updates and stores the two-dimensional parameter table data in real time and for a long time during dynamic operation, so that the data record is adjusted immediately with the change of the vehicle operating conditions, without fear of power interruption, and data security. At the same time, the data export function allows the stored control strategy data to be exported to an external analysis platform through the controller area network (Controller Area Network, CAN) bus, which promotes the secondary use of data and provides a rich historical data source, facilitates in-depth analysis, model verification and strategy iteration optimization, and is easy to integrate into various hydrogen energy vehicle platforms. It has strong scalability and continuously improves the intelligence level and system efficiency of hydrogen and oxygen fuel cell water temperature control.

[0042] For example, in the embodiment of the present application, the acquisition module 101 can also automatically identify abnormal conditions such as sensor disconnection, short circuit, or readings outside the normal range, and issue a warning to the control module 103 or start a backup plan, that is, establish an error detection and fault-tolerant processing mechanism to ensure data continuity and system security.

[0043] The hydrogen and oxygen fuel cell water temperature control device provided in the embodiment of the present application obtains the vehicle's ambient temperature collected by the ambient temperature sensor and the current output value collected by the current sensor in real time, and then automatically and dynamically searches for the fan basic opening value corresponding to the vehicle's ambient temperature and the current output value in a two-dimensional parameter table containing the ambient temperature and the output current. The cooling system of the hydrogen and oxygen fuel cell can be adjusted based on the fan basic opening value to control the operating temperature of the hydrogen and oxygen fuel cell, thereby making it possible to flexibly adjust the water temperature control parameters according to actual operating conditions, thereby improving the performance and life of the fuel cell.

[0044] Based on the above embodiments, the present application provides a method for controlling the water temperature of a hydrogen-oxygen fuel cell. The method for controlling the water temperature of a hydrogen-oxygen fuel cell can be applied to Figure 1 to Figure 5 In the hydrogen and oxygen fuel cell water temperature control device 100 of the corresponding embodiment. Please refer to Figure 6 The water temperature control method of the hydrogen-oxygen fuel cell specifically includes the following steps:

[0045] S101, obtaining the ambient temperature of the vehicle collected by the ambient temperature sensor and the current output value collected by the current sensor, where the current sensor is installed at the output end of the hydrogen-oxygen fuel cell.

[0046] For example, the embodiment of the present application can obtain the vehicle's ambient temperature collected by the ambient temperature sensor and the current output value collected by the current sensor through the acquisition module 101 in the hydrogen-oxygen fuel cell water temperature control device 100. The ambient temperature sensor is installed at the bottom of the vehicle cab to detect the real atmospheric temperature, and the data is true and reliable. The current sensor is installed at the output end of the hydrogen-oxygen fuel cell, which is convenient for real-time detection and feedback of the current output value of the stack under different load conditions, and enhances the instant response of the control. For another example, the embodiment of the present application can also automatically identify abnormal situations such as sensor disconnection, short circuit or readings beyond the normal range, that is, establish an error detection and fault-tolerant processing mechanism to ensure the continuity of data and the security of the system.

[0047] S102, searching, according to the ambient temperature of the vehicle and the current output value, a basic fan opening value corresponding to the ambient temperature of the vehicle and the current output value in a two-dimensional parameter table including the ambient temperature and the output current.

[0048] For example, in the embodiment of the present application, the table lookup module 102 in the hydrogen-oxygen fuel cell water temperature control device 100 can search the fan basic opening value corresponding to the ambient temperature and current output value of the vehicle in the two-dimensional parameter table. For example, in the early stage of establishing the two-dimensional parameter table, the two-dimensional parameter table is preliminarily calibrated through laboratory tests and preliminary road tests of the vehicle, and the uncalibrated area is reasonably filled to form preliminary control parameters. During the operation of the vehicle, by detecting whether the change in the ambient temperature of the vehicle and the current output value meets the preset steady-state operating conditions, and when the change meets the preset steady-state operating conditions, the two-dimensional parameter table is automatically and immediately updated, that is, through the continuous self-learning process, the fuel cell water temperature can be more accurately controlled, and the impact of temperature fluctuations on the performance of the fuel cell can be reduced, thereby improving the overall work efficiency, extending the service life of the fuel cell and reducing energy consumption.

[0049] For another example, the embodiment of the present application can also perform data verification on the two-dimensional parameter table. If the verification result is abnormal, the current two-dimensional parameter table is switched to the backup parameter table. The backup parameter table is the two-dimensional parameter table when the hydrogen and oxygen fuel cell is initially working, that is, it automatically switches to the safety mode to maintain the basic water temperature control function and ensure the safety of vehicle operation. For another example, the embodiment of the present application can also store and export the two-dimensional parameter table, promote the secondary use of data and provide a rich historical data source, facilitate in-depth analysis, model verification and strategy iteration optimization, and continuously improve the intelligence level and system efficiency of hydrogen and oxygen fuel cell water temperature control.

[0050] S103, adjusting the cooling system of the hydrogen-oxygen fuel cell based on the basic fan opening value to control the operating temperature of the hydrogen-oxygen fuel cell.

[0051] For example, in the embodiment of the present application, the cooling system of the hydrogen and oxygen fuel cell can be adjusted by the control module 103 in the hydrogen and oxygen fuel cell water temperature control device 100, thereby controlling the operating temperature of the hydrogen and oxygen fuel cell.

The cooling system of the hydrogen and oxygen fuel cell can be adjusted based on the fan basic opening value to control the operating temperature of the hydrogen and oxygen fuel cell, thereby making it possible to flexibly adjust the water temperature control parameters according to actual operating conditions, thereby improving the performance and life of the fuel cell.
