[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings 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.

[0046] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present 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 chemical reactions that consume energy to generate energy. Conventional cars and hybrid electric vehicles produce carbon emissions when using traditional fuels such as gasoline, diesel, and liquefied gas. Electricity for pure electric vehicles comes from the power grid, but since a considerable proportion of power generation from the power grid still relies on fossil fuels, electricity from the power grid is still an energy source that produces carbon emissions.

[0049] Carbon emission reduction: Hydrogen is a clean energy source, and its manufacture, production and reaction do not produce carbon emissions. Therefore, the energy generated by using hydrogen can be converted to grid electricity, which is equivalent to reducing the corresponding carbon emissions. Based on this, the carbon emission reduction of hydrogen energy can be calculated, that is, the carbon emission reduction saved by using hydrogen energy.

[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 charged externally, which 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 energy is a clean energy that does not produce carbon emissions during its reaction process. In order to show the clean energy and zero-carbon effect of fuel cell vehicles to users, it is necessary to estimate the vehicle's driving energy consumption data and display the amount of hydrogen consumed during the journey on the vehicle's display interface, as well as the amount of carbon emissions reduced after hydrogen energy conversion, in order to encourage users to use clean energy.

[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present 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 a fuel cell vehicle in this application. Figure 1 As shown in the figure, the calculation method of carbon emission saving 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 important electrical components and power supply lines in fuel cell vehicles, and uses the vehicle data acquisition system to collect data and calculate 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 a fuel cell vehicle system structure provided in one embodiment of the present application, Figure 2 Arrange multiple measuring points in the system. The purposes of arranging each measuring point are 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 from the fuel cell system to the power battery during the current trip, specifically, the vehicle data acquisition system obtains the first electric energy transmitted from the fuel cell system to the power battery during the current trip 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 from the fuel cell system to the drive motor during the current trip, specifically, the vehicle data acquisition system obtains the second electric energy for driving transmitted from the fuel cell system to the drive motor during the current trip 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 from the power battery to the drive motor during the current trip, the third electric energy consists of positive energy consumption and negative energy consumption, and is obtained by the power The driving energy consumption transmitted from the battery to the driving motor is positive energy consumption, and the energy consumption for energy recovery and charging from the driving motor to the power battery 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 in the current journey, specifically the accumulated electric energy charged 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 in the current journey, specifically 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 in the current journey, specifically by reading the current and voltage at measuring point ⑦ and integrating them.

[0060] It can be understood that the electric energy cumulatively output by the fuel cell system in the current trip is mainly transmitted to the power battery, the motor and various power-consuming components to drive the vehicle to travel normally. The first electric energy transmitted to the power battery and the second electric energy transmitted to the drive motor by the fuel cell system in the current trip are calculated to determine the electric energy cumulatively output by the fuel cell system in the current trip.

[0061] Step 120: Add the first electric energy and the second electric energy to obtain the electric energy cumulatively output by the fuel cell system in 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 journey, the first electric energy and the second electric energy are added together to obtain the electric energy cumulatively output by the fuel cell system during the current journey.

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

[0064] Furthermore, after obtaining the cumulative electric energy output by the fuel cell system in the current journey, the carbon emission factor of the electric energy is converted to estimate the carbon emissions saved by the fuel cell vehicle in the current journey through the consumption of hydrogen for power generation, that is, the cumulative carbon emissions saved by the fuel cell system in the current journey. After obtaining the cumulative carbon emissions saved by the fuel cell system in the current journey, the value is displayed in the display interface such as the dashboard of the vehicle so that the user can promptly understand how much carbon emissions have been reduced in the current journey.

[0065] The carbon emission factor and the electric energy cumulatively output by the fuel cell system in the current trip are used to determine the cumulative carbon emission saved by the fuel cell system in 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 in the current trip are calculated; the first electric energy and the second electric energy are added to obtain the electric energy cumulatively output by the fuel cell system in the current trip; further based on the carbon emission factor and the electric energy cumulatively output by the fuel cell system in the current trip, the cumulative carbon emissions saved by the fuel cell system in the current trip are determined and displayed on the display interface of the vehicle, so as to show the user the carbon emissions saved by the use of hydrogen in the hydrogen fuel cell vehicle in the current trip, so as to achieve 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 comprises:

[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 in the current trip, the total carbon emissions saved by the fuel cell system are determined and displayed on the display interface of the vehicle. 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, the carbon emissions reduction equivalent to the total mileage traveled by the fuel cell vehicle can be converted according to the above formula, 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 electric energy used by the external charging pile to charge the power battery is still a carbon emission energy source, and the carbon emissions generated by its power grid power supply need to be estimated. When the vehicle is a rechargeable fuel cell vehicle, the method further includes:

[0076] Step 210, calculating the cumulative electric energy consumed by the power battery in the current trip;

[0077] It can be understood 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 the first electric energy is subtracted 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 in the current trip, determine the cumulative carbon emissions generated by the power battery in the current trip and display it on the display interface of the vehicle. 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 trip, 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 in the current trip, the carbon emissions generated by the power battery in the fuel cell vehicle in the current trip can be estimated by converting the carbon emission factor of the electric energy, that is, the cumulative carbon emissions generated by the power battery in the current trip. After obtaining the cumulative carbon emissions generated by the power battery in the current trip, the value is displayed in the display interface such as the dashboard of the vehicle, so that the user can timely understand the carbon emissions generated by using the power grid to charge in 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 in the current journey is calculated; then based on the carbon emission factor and the cumulative electric energy consumed by the power battery in the current journey, the cumulative carbon emissions generated by the power battery in the current journey are determined and displayed on the display interface of the vehicle, so as to show the user the carbon emissions generated by charging the hydrogen fuel cell vehicle using the power grid in the current journey, thereby achieving the purpose of encouraging users to use clean energy.

[0084] Furthermore, the cumulative carbon emissions saved by the fuel cell system in the current trip and the cumulative carbon emissions generated by the power battery in the current trip can be subtracted to determine the total carbon emissions saved in the current trip and display it in the vehicle's dashboard or other display interface. For example, in the current trip, the cumulative carbon emissions saved by the fuel cell system in the current trip is 1.75kg, and the cumulative carbon emissions generated by the power battery in the current trip is 0.59kg. Subtracting the two, the total carbon emissions saved in the current trip is 1.16kg.

[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 electric energy output by the fuel cell system in the current trip, the cumulative electric 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, the total carbon emissions saved by the fuel cell system are determined and displayed on the display interface of the vehicle. 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 is the cumulative electrical energy output by the fuel cell system during the current trip, P pb M is the cumulative electric energy consumed by the power battery in the current trip. 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 of the fuel cell system and the cumulative electric energy consumed by the power battery within the total journey is converted into a mileage sharing ratio, and at the same time combined with the total mileage of the vehicle, the carbon emissions 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 in 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 and displayed on the display interface of the vehicle based on the total mileage of the vehicle, the mileage of the current trip, the cumulative electric energy output by the fuel cell system in the current trip, the cumulative electric 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 to show the user the carbon emissions saved by the use of hydrogen in the hydrogen fuel cell vehicle during the total journey of the vehicle, 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.

[0092] In one embodiment, referring to Figure 3 , Figure 3 This is a functional module diagram of an embodiment of a device for calculating the carbon emissions saved by a fuel cell vehicle of the present application. Figure 3 As shown, the fuel cell vehicle carbon emission saving calculation device 300 includes:
