[0045] 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.

[0046] First, some technical terms in this application are explained to facilitate those skilled in the art to understand this application.

[0047] Fuel cell system: A device in a fuel cell vehicle that uses hydrogen as fuel to react chemically with air to generate electricity. It is also called a fuel-electric system and mainly includes a hydrogen supply system, an air supply system, a fuel cell stack, an exhaust system, and a cooling system.

[0048] Carbon emissions: CO2 emissions from the chemical reactions that produce energy through energy consumption. Conventional and hybrid electric vehicles generate carbon emissions when they use traditional fuels like gasoline, diesel, and LPG. Pure electric vehicles draw their electricity from the grid, but since a significant portion of grid power generation still relies on fossil fuels, grid electricity still generates carbon emissions.

[0049] Carbon Emission Reduction: Hydrogen is a clean energy source; its manufacture, production, and reactions produce no carbon emissions. Therefore, the energy generated by hydrogen can be converted to grid electricity, effectively reducing carbon emissions. This can be used to calculate the carbon reduction from hydrogen energy, i.e., the amount of carbon emissions saved by using hydrogen.

[0050] Rechargeable fuel cell vehicle: an externally rechargeable fuel cell vehicle with two power sources: a fuel cell system and a power battery, wherein the power battery can be charged by an external charging port.

[0051] Non-rechargeable fuel cell vehicle: that is, a fuel cell vehicle that cannot be externally charged. It has two power sources: the fuel cell system and the power battery, of which the power battery can only be charged by the fuel cell system.

[0052] Hydrogen is a clean energy source that produces no carbon emissions during its reaction. To demonstrate the zero-carbon nature of fuel cell vehicles to users, it's necessary to estimate the amount of hydrogen consumed during a trip based on the vehicle's energy consumption data and display it on the vehicle's display screen. This, along with the equivalent reduction in carbon emissions from the hydrogen energy used, will encourage users to use clean energy.

[0053] 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.

[0054] In a first aspect, an embodiment of the present application provides a method for calculating the carbon emissions saved by a fuel cell vehicle.

[0055] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for calculating the carbon emissions saved by fuel cell vehicles in this application. Figure 1 As shown in the figure, the calculation method for saving carbon emissions of fuel cell vehicles includes:

[0056] Step 110 , calculating the first electric energy transmitted to the power battery and the second electric energy transmitted to the drive motor by the fuel cell system during the current trip;

[0057] In specific implementation, this application classifies the carbon emissions of fuel cell vehicles from the perspective of energy flow, according to carbon emission energy and carbon emission reduction energy, measures the energy of each important electrical component and power supply line in the fuel cell vehicle, and the vehicle data acquisition system collects data and calculates the driving electric energy contributed by the hydrogen consumed by the fuel cell vehicle and the electric energy contributed by the power battery.

[0058] Figure 2 A simplified schematic diagram of the fuel cell vehicle system structure provided in one embodiment of the present application is shown in FIG. Figure 2 Arrange multiple measuring points in the , the purpose of arranging each measuring point is as follows:

[0059] Measuring point ① is used to obtain the mass of hydrogen consumed, specifically, the vehicle data acquisition system obtains the mass of hydrogen consumed by reading the hydrogen supply system data and calculating it, wherein the hydrogen supply system data includes the hydrogen tank pressure and temperature; measuring point ② is used to obtain the first electric energy transmitted by the fuel cell system to the power battery during the current journey, specifically, the vehicle data acquisition system obtains the first electric energy by reading the current and voltage at measuring point ② and integrating it; measuring point ③ is used to obtain the second electric energy for driving transmitted by the fuel cell system to the drive motor during the current journey, specifically, the vehicle data acquisition system obtains the second electric energy for driving transmitted by the fuel cell system to the drive motor during the current journey, specifically, the vehicle data acquisition system obtains the second electric energy by reading the current and voltage at measuring point ③ and integrating it; measuring point ④ is used to obtain the third electric energy transmitted by the power battery to the drive motor during the current journey, the third electric energy consists of positive energy consumption and negative energy consumption, and is composed of the power battery. The driving energy consumption transmitted from the battery to the drive motor is positive energy consumption, and the energy consumption for energy recovery and charging of the power battery by the drive motor is negative energy consumption, which is specifically obtained by the vehicle data acquisition system by reading the current and voltage at measuring point ④ and integrating them; measuring point ⑤ is used to obtain the fourth electric energy obtained by the power battery from charging the power grid during the current journey, specifically the accumulated electric energy obtained from the charging device; measuring point ⑥ is used to obtain the fifth electric energy transmitted by the power battery to the low-voltage accessories during the current journey, specifically by the vehicle data acquisition system by reading the current and voltage at measuring point ⑥ and integrating them; measuring point ⑦ is used to obtain the sixth electric energy transmitted by the power battery to the high-voltage accessories during the current journey, specifically by the vehicle data acquisition system by reading the current and voltage at measuring point ⑦ and integrating them.

[0060] It is understood that the cumulative electrical energy output by the fuel cell system during the current trip is primarily transmitted to the power battery, motor, and various electrical components to drive the vehicle normally. The first electrical energy transmitted to the power battery and the second electrical energy transmitted to the drive motor by the fuel cell system during the current trip are calculated to determine the cumulative electrical energy output by the fuel cell system during the current trip.

[0061] Step 120: Add the first electric energy and the second electric energy to obtain the cumulative electric energy output by the fuel cell system during the current trip;

[0062] Furthermore, after obtaining the first electric energy transmitted to the power battery and the second electric energy transmitted to the drive motor by the fuel cell system during the current trip, the first electric energy and the second electric energy are added together to obtain the cumulative electric energy output by the fuel cell system during the current trip.

[0063] Step 130: Based on the carbon emission factor and the cumulative electrical energy output by the fuel cell system during the current trip, determine the cumulative carbon emissions saved by the fuel cell system during the current trip and display it on a display interface of the vehicle.

[0064] Furthermore, after obtaining the cumulative electrical energy output by the fuel cell system during the current trip, the carbon emissions saved by the fuel cell vehicle due to hydrogen consumption and electricity generation during the current trip can be converted using the carbon emission factor of the electrical energy. This is the cumulative carbon emissions saved by the fuel cell system during the current trip. After obtaining the cumulative carbon emissions saved by the fuel cell system during the current trip, this value is displayed on a display interface such as the vehicle's instrument panel, allowing users to promptly understand the extent of carbon emissions reduction during the current trip.

[0065] The carbon emission factor and the cumulative electric energy output by the fuel cell system during the current trip are used to determine the cumulative carbon emission saved by the fuel cell system during the current trip. The corresponding formula is:

[0066] M fc1 =P fc *δ

[0067] Among them, P fc is the cumulative output of the fuel cell system in the current trip, δ is the carbon emission factor, M fc1 The cumulative carbon emissions saved by the fuel cell system during the current journey.

[0068] In this embodiment, the first electric energy transmitted to the power battery and the second electric energy transmitted to the drive motor by the fuel cell system during the current trip are calculated; the first electric energy and the second electric energy are added together to obtain the cumulative electric energy output by the fuel cell system during the current trip; and further based on the carbon emission factor and the cumulative electric energy output by the fuel cell system during the current trip, the cumulative carbon emissions saved by the fuel cell system during the current trip are determined and displayed on the vehicle's display interface, so as to show the user the carbon emissions saved by the use of hydrogen in the hydrogen fuel cell vehicle during the current trip, thereby achieving the purpose of encouraging users to use clean energy.

[0069] Furthermore, in one embodiment, when the vehicle is a non-rechargeable fuel cell vehicle, the method further includes:

[0070] Based on the total mileage of the vehicle, the mileage of the current trip, and the cumulative carbon emissions saved by the fuel cell system during the current trip, the total carbon emissions saved by the fuel cell system are determined and displayed on the vehicle's display interface. The corresponding formula is:

[0071]

[0072] Among them, M fc1 is the cumulative carbon emissions saved by the fuel cell system in the current journey, d1 is the mileage of the current journey, and d s is the total vehicle mileage, M fc2 Total carbon emissions saved for the fuel cell system.

[0073] It can be understood that when the vehicle is a non-rechargeable fuel cell vehicle, according to the above formula, the carbon emissions reduction equivalent to the total mileage traveled by the fuel cell vehicle can be converted, that is, the total carbon emissions saved by the fuel cell system, and displayed on the vehicle's dashboard and other display interfaces, so that users can promptly understand how much carbon emissions have been reduced in the total vehicle journey.

[0074] In this embodiment, based on the total mileage of the vehicle, the mileage of the current trip and the cumulative carbon emissions saved by the fuel cell system in the current trip, the total carbon emissions saved by the fuel cell system are determined and displayed on the vehicle's display interface to show the user the carbon emissions saved by the use of hydrogen in the hydrogen fuel cell vehicle during the total vehicle trip, thereby achieving the purpose of encouraging users to use clean energy.

[0075] Furthermore, in one embodiment, the electricity used by the external charging station to charge the power battery is still a carbon-emitting energy source, and it is necessary to estimate the carbon emissions generated by its grid power supply. When the vehicle is a rechargeable fuel cell vehicle, the method further includes:

[0076] Step 210: Calculate the cumulative electric energy consumed by the power battery during the current trip;

[0077] It is understandable that when the vehicle is a rechargeable fuel cell vehicle, in addition to discharging, the power battery will also be charged by the fuel cell system and the drive motor will recover energy from the power battery. Therefore, this part of the charging energy consumption needs to be excluded to obtain the accurate cumulative electrical energy consumed by the power battery in the current journey. Therefore, the cumulative electric energy consumed by the power battery in the current trip is composed of the third electric energy transmitted by the power battery to the drive motor in the current trip, the fourth electric energy obtained by the power battery from charging the power grid in the current trip, the fifth electric energy transmitted by the power battery to the low-voltage accessories in the current trip, the sixth electric energy transmitted by the power battery to the high-voltage accessories in the current trip, and the first electric energy transmitted by the fuel cell system to the power battery in the current trip; specifically, the first electric energy transmitted to the power battery by the fuel cell system in the current trip is obtained through measuring point ②; the second electric energy for driving transmitted by the fuel cell system to the drive motor in the current trip is obtained through measuring point ③; the third electric energy transmitted to the drive motor by the power battery in the current trip is obtained through measuring point ④; the fourth electric energy obtained by the power battery from charging the power grid in the current trip is obtained through measuring point ⑤; the fifth electric energy transmitted by the power battery to the low-voltage accessories in the current trip is obtained through measuring point ⑥; and the sixth electric energy transmitted by the power battery to the high-voltage accessories in the current trip is obtained through measuring point ⑦.

[0078] After obtaining the third electric energy, the fourth electric energy, the fifth electric energy, the sixth electric energy and the first electric energy, the third electric energy, the fourth electric energy, the fifth electric energy and the sixth electric energy are added together and then subtracted from the first electric energy to obtain the cumulative electric energy consumed by the power battery in the current trip.

[0079] Step 220: Based on the carbon emission factor and the cumulative electric energy consumed by the power battery during the current trip, determine the cumulative carbon emissions generated by the power battery during the current trip and display it on the vehicle display interface. The corresponding formula is:

[0080] M ee =P pb *δ

[0081] Among them, P pb is the cumulative electric energy consumed by the power battery in the current journey, δ is the carbon emission factor, M ee It is the cumulative carbon emissions generated by the power battery during the current journey.

[0082] Furthermore, after obtaining the cumulative electric energy consumed by the power battery during the current trip, the carbon emissions generated by the power battery in the fuel cell vehicle during the current trip can be converted using the carbon emission factor of the electric energy to estimate the carbon emissions generated by the power battery during the current trip, namely the cumulative carbon emissions generated by the power battery during the current trip. After obtaining the cumulative carbon emissions generated by the power battery during the current trip, this value is displayed on a display interface such as the vehicle's instrument panel, so that users can promptly understand the carbon emissions generated by using grid charging during the current trip.

[0083] In this embodiment, when the vehicle is a rechargeable fuel cell vehicle, the cumulative electric energy consumed by the power battery during the current trip is calculated; then, based on the carbon emission factor and the cumulative electric energy consumed by the power battery during the current trip, the cumulative carbon emissions generated by the power battery during the current trip are determined and displayed on the vehicle's display interface. This shows the user the carbon emissions generated by charging the hydrogen fuel cell vehicle using the power grid during the current trip, thereby encouraging users to use clean energy.

[0084] Furthermore, the cumulative carbon emissions saved by the fuel cell system during the current trip can be subtracted from the cumulative carbon emissions generated by the power battery during the current trip to determine the total carbon emissions saved for the current trip and display it on a display interface such as the vehicle's instrument panel. For example, during the current trip, the cumulative carbon emissions saved by the fuel cell system during the current trip are 1.75 kg, and the cumulative carbon emissions generated by the power battery during the current trip are 0.59 kg. Subtracting the two yields a total carbon emissions saved of 1.16 kg.

[0085] Furthermore, in one embodiment, the method further includes:

[0086] Based on the total mileage of the vehicle, the mileage of the current trip, the cumulative electrical energy output by the fuel cell system during the current trip, the cumulative electrical energy consumed by the power battery during the current trip, and the cumulative carbon emissions saved by the fuel cell system during the current trip, the total carbon emissions saved by the fuel cell system are determined and displayed on the vehicle's display interface. The corresponding formula is:

[0087]

[0088] Among them, M fc1 is the cumulative carbon emissions saved by the fuel cell system in the current journey, d1 is the mileage of the current journey, and d s is the total vehicle mileage, P fc P is the cumulative output of the fuel cell system in the current trip. pb M is the cumulative energy consumed by the power battery during the current journey. fc2 Total carbon emissions saved for the fuel cell system.

[0089] It can be understood that when the vehicle is a rechargeable fuel cell vehicle, the ratio between the cumulative electric energy output by the fuel cell system and the cumulative electric energy consumed by the power battery during the total journey is converted into a mileage sharing ratio. At the same time, combined with the total mileage of the vehicle, the carbon emission reduction equivalent to the total mileage traveled by the fuel cell vehicle is calculated, that is, the total carbon emissions saved by the fuel cell system, and displayed on the vehicle's dashboard and other display interfaces, so that users can promptly understand how much carbon emissions have been reduced during the total vehicle journey.

[0090] In this embodiment, when the vehicle is a rechargeable fuel cell vehicle, the total carbon emissions saved by the fuel cell system are determined based on the total mileage of the vehicle, the mileage of the current trip, the cumulative electrical energy output by the fuel cell system in the current trip, the cumulative electrical energy consumed by the power battery in the current trip, and the cumulative carbon emissions saved by the fuel cell system in the current trip. This is displayed on the vehicle's display interface to show the user the carbon emissions saved by the use of hydrogen in the hydrogen fuel cell vehicle during the total vehicle trip, thereby encouraging users to use clean energy.

[0091] In a second aspect, an embodiment of the present application also provides a device for calculating the carbon emissions saved by a fuel cell vehicle.
