[0034] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0035] In response to the above-mentioned background technical issues, the present application provides a hydrogen consumption calculation method that can accurately calculate the hydrogen consumption of a vehicle under different loads and usage scenarios over a long period of time, thereby providing accurate and effective data support for the use of vehicle hydrogen fuel cells and vehicle energy consumption optimization. The following describes the hydrogen consumption calculation method, device, vehicle, storage medium, and computer program of the embodiments of the present application with reference to the accompanying drawings.

[0036] Specifically, FIG1 is a flow chart of a method for calculating hydrogen consumption provided in an embodiment of the present application.

[0037] As shown in FIG1 , the hydrogen consumption calculation method includes the following steps:

[0038] In step S101 , the change in the state of charge of the fuel cell from the target time to the current time is obtained.

[0039] The target time may be selected according to actual conditions, for example, 60 seconds ago, etc., and there is no specific limitation on this.

[0040] It is understandable that since the SOC (state of charge) of the fuel cell will fluctuate normally during driving, the embodiment of the present application can obtain the SOC change of the fuel cell, thereby obtaining the corresponding hydrogen consumption; among them, the embodiment of the present application can set a target time and obtain the SOC change within a certain period of time from the target time to the current time.

[0041] Therefore, the embodiment of the present application can calculate the corresponding hydrogen consumption according to the SOC difference, thereby improving the accuracy of hydrogen consumption calculation and meeting actual needs.

[0042] The embodiment of the present application can use at least one method to obtain the SOC change, which is not specifically limited. For example, the embodiment of the present application can record the initial SOC value of the fuel cell after the vehicle is started and the hydrogen fuel cell starts to run; the embodiment of the present application can set the target time to be 60 seconds different from the current time, and then calculate the difference between the current SOC and the SOC at the target time within a 60-second period.

[0043] In an embodiment of the present application, before obtaining the change in charge state of the fuel cell from the target moment to the current moment, it also includes: identifying whether the vehicle is in an external charging state; if the vehicle is in an external charging state, accumulating the total external charging power of the power battery according to the external charging power.

[0044] It can be understood that in addition to obtaining the charge state of the vehicle's fuel cell, the embodiment of the present application can also obtain the current state of the vehicle, identify and determine whether the vehicle is in an external charging state; when the vehicle is in an external charging state, the external charging power is added to the total external charging power, and when the vehicle is not in an external charging state, no operation is performed.

[0045] Therefore, the embodiment of the present application can take external charging change data into consideration, so that the total external charging power is adapted to the current vehicle, thereby improving the calculation accuracy; at the same time, the embodiment of the present application can meet the calculation requirements under long-term complex working conditions.

[0046] The embodiment of the present application can use at least one method to obtain the SOC change, which is not specifically limited. For example, when the vehicle is charged by an external device, the embodiment of the present application can record the initial charging capacity value of the power battery; then calculate the difference Δ between the current power battery charging capacity and the previous power battery charging capacity within a certain period. E , where this period can be calibrated and adjusted according to the actual situation, for example, it can be calibrated to 60s, etc., and there is no specific limitation on this; E Added to the total charge of the vehicle E batDuring the charging process of the power battery, the charging power will be continuously calculated and accumulated into E bat middle.

[0047] In step S102 , the total hydrogen consumption of the fuel cell at the current moment is determined according to the change in the state of charge and the total hydrogen consumption of the fuel cell at the target moment.

[0048] It is understandable that the embodiment of the present application can convert the corresponding hydrogen consumption according to the change in the state of charge, and then use the corresponding hydrogen consumption and the total hydrogen consumption at the target moment to obtain the total hydrogen consumption of the fuel cell at the current moment.

[0049] Therefore, the embodiment of the present application can use the fuel cell SOC to accurately calculate the corresponding hydrogen consumption; at the same time, since the embodiment of the present application can take the changing SOC value into consideration in the calculation and continuously accumulate the hydrogen consumption corresponding to the changing SOC to the total hydrogen consumption, the embodiment of the present application can filter out some fluctuations and differences through the continuous accumulation of data, eliminate the process of sudden changes in hydrogen consumption under special working conditions or environments, and meet the requirements for accuracy and reliability of hydrogen consumption calculation under long-term complex working conditions.

[0050] Specifically, the total hydrogen consumption of the fuel cell at the current moment is determined based on the change in state of charge and the total hydrogen consumption of the fuel cell at the target moment, including: calculating the hydrogen consumption from the target moment to the current moment based on the change in state of charge; calculating the total hydrogen consumption of the fuel cell at the current moment based on the total hydrogen consumption of the fuel cell at the target moment and the hydrogen consumption from the target moment to the current moment.

[0051] It is understandable that the embodiment of the present application can obtain the charge state change amount Then, the conversion relationship is used to calculate Corresponding hydrogen consumption M Δ , thus M Δ The total hydrogen consumption M added to the vehicle th In this way, the total amount of hydrogen consumed by the fuel cell at the current moment can be obtained; wherein, the conversion relationship between the change in state of charge and the corresponding hydrogen consumption can be obtained by at least one method, such as calibration based on experimental data, or calibration based on finding conversion rules, etc., and there is no specific limitation on this; at the same time, the built-in calibration parameters of the embodiment of the present application can be continuously optimized to adapt to the actual operating conditions of the vehicle.

[0052] Therefore, the embodiment of the present application can use the charge state change to calculate the total hydrogen consumption of the fuel cell at the current moment in real time, so that as the hydrogen fuel cell runs, the hydrogen consumption corresponding to the charge state change is continuously calculated and accumulated into the total hydrogen consumption M. thIn this way, the accuracy of hydrogen consumption calculation is improved to meet the needs of hydrogen consumption calculation under long-term and complex working conditions.

[0053] In the embodiment of the present application, the calculation formula of the fuel cell state of charge is:

[0054] Among them, C H2 is the hydrogen consumption of the vehicle per 100 kilometers, M th is the total hydrogen consumption of the vehicle; K fc is the conversion coefficient between hydrogen consumption and fuel cell output power. It is an actual test value. The coefficients of different fuel cell manufacturers vary and can be confirmed based on actual usage. There is no specific limit on this. D is the total mileage of the vehicle. f is the abnormal driving distance of the vehicle, E bat The total external charging capacity charged to the vehicle via an external charging device.

[0055] It is understandable that, as shown in FIG2 , when the vehicle is powered on, the embodiment of the present application can read the total hydrogen consumption M of the vehicle. th , total mileage D, total external charging power E bat , wherein, in the embodiment of the present application, the total amount of hydrogen consumption of the vehicle stored in the controller can be read through the vehicle controller during initialization; the total amount of hydrogen consumption is multiplied by the conversion coefficient to obtain the corresponding total amount of electricity output by the fuel cell, and the total amount of electricity output by the fuel cell is added to the total amount of external charging to obtain the total amount of electricity output by the vehicle; the total amount of electricity output by the fuel cell is then compared with the total amount of electricity output by the vehicle to obtain the proportion of the fuel cell output electricity to the total amount of electricity, and the proportion is multiplied by the vehicle mileage excluding abnormal driving distance to obtain the mileage of the vehicle supplied by the fuel cell; the total amount of hydrogen consumption is divided by the mileage of the vehicle supplied by the fuel cell, and the units are converted to obtain the hydrogen consumption of the vehicle per 100 kilometers.

[0056] Therefore, the embodiment of the present application can calculate the total hydrogen consumption of the vehicle based on the hydrogen fuel cell SOC change cycle, and calculate the total charge of the vehicle based on the power battery charge change cycle. The calculation method is simple, the process is rigorous, and the results are accurate. It eliminates factors that interfere with the calculation and fits the actual working conditions of the vehicle. At the same time, this calculation method facilitates the transplantation of algorithms for different projects and has a wider range of applicability. Its built-in calibration parameters can be continuously optimized with higher accuracy to meet actual usage needs.

[0057] It should be noted that when the vehicle is powered off, after ensuring that the vehicle has stopped running and the hydrogen fuel cell has stopped working, the embodiment of the present application can also calculate the total hydrogen consumption M of the vehicle. th , the total external charging power E charged to the vehicle through the external charging device batThe data is stored in the EEPROM (Electrically Erasable Programmable read only memory) inside the vehicle controller. This data will not be lost after power is turned off, so it is used as the initial value for calculation when the vehicle controller is powered on next time.

[0058] According to the hydrogen consumption calculation method proposed in the embodiment of the present application, the total amount of hydrogen consumption can be confirmed based on the change in the charge state of the fuel cell, and the hydrogen consumption of the fuel cell can be calculated based on the total amount of hydrogen consumption, and the calculation result is more accurate and reliable; and because the changing charge state value of the fuel cell is taken into consideration, the embodiment of the present application can filter out some fluctuations and differences through the continuous accumulation of data, eliminate the process of sudden changes in hydrogen consumption under special working conditions or environments, and meet the requirements for accuracy and reliability of hydrogen consumption calculation under long-term complex working conditions.
