[0002] Countries around the world have gradually announced the time to ban the sale of fuel vehicles, and new energy vehicles are gradually becoming a historical stage. Hydrogen fuel cell vehicles have gradually gained attention from various countries due to their advantages such as zero emissions, fast hydrogen refueling, and long driving range, and have become one of the important development directions in the field of new energy vehicles in the future. As a secondary energy source, hydrogen has the advantages of diverse sources, zero terminal emissions, wide applications, and high mass energy density, and is one of the important components of the future power structure.

[0003] Among the related technologies, proton exchange membrane fuel cells are easily affected by their reaction characteristics.

[0024] Embodiments of the present application are described in detail below, and examples of the embodiments 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.

[0025] The following describes the multi-power source control method, device, vehicle, storage medium and program product of the vehicle of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that a single power source vehicle is difficult to operate efficiently and the overall cost of a higher power level is high in the related art mentioned in the background technology center, the present application provides a multi-power source control method for a vehicle, in which the waste water generated by the fuel cell can be converted into steam to ensure the humidity of the hydrogen internal combustion engine, and can be reduced to hydrogen and oxygen to supply the hydrogen internal combustion engine for combustion, while ensuring pollution-free and zero emissions, improving the utilization rate of hydrogen, and according to the current state of charge of the power battery and the current power demand of the vehicle, coordinating the control of at least one output power of the fuel cell, hydrogen internal combustion engine and power battery of the vehicle, so that the working efficiency of the system can be comprehensively improved, and the overall cost of the system can be reduced, and the applicability is high. Thus, the problems that a single power source vehicle is difficult to operate efficiently and the overall cost of a higher power level in the related art are solved.

[0026] Specifically, Figure 1 A schematic flow chart of a method for controlling multiple power sources of a vehicle provided in an embodiment of the present application.

[0027] like Figure 1 As shown, the multi-power source control method of the vehicle includes the following steps:

[0028] In step S101 , the current required power of the vehicle and the current state of charge of the power battery are obtained.

[0029] It is understandable that the embodiments of the present application can obtain the current required power of the vehicle and the current charge state of the power battery, so as to facilitate the subsequent coordinated control of at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery.

[0030] It should be noted that the current required power of the vehicle is determined based on the actual operating state of the vehicle at a certain moment and the driver's operating intention, wherein the required power reflects the power output required by the vehicle under specific working conditions to meet different driving needs such as acceleration, speed maintenance, and climbing. The present application can collect real-time data through various sensors (such as accelerator pedal position sensor, vehicle speed sensor, acceleration sensor, slope sensor, etc.).

[0031] For example, based on the driver's operation, the driver's needs can be judged by detecting the position of the accelerator pedal. The accelerator pedal position sensor can provide a signal indicating the degree to which the driver wants the vehicle to accelerate; the position of the brake pedal can also be used to determine whether the vehicle needs to slow down or stop, thereby adjusting the required power.

[0032] In step S102 , the discharge power of the power battery is determined according to the current state of charge of the power battery.

[0033] It can be understood that the embodiments of the present application can determine the discharge power of the power battery according to the current state of charge of the power battery, so as to facilitate the subsequent coordinated control of at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery.

[0034] In step S103, the output power of at least one of the fuel cell, the hydrogen internal combustion engine and the power battery of the vehicle is cooperatively controlled according to the discharge power and the required power.

[0035] It can be understood that the embodiments of the present application can collaboratively control at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery according to the discharge power and demand power, thereby comprehensively improving the system's operating efficiency and reducing the overall cost of the system, and has high applicability.

[0036] In an embodiment of the present application, at least one output power of a vehicle's fuel cell, hydrogen internal combustion engine, and power battery is cooperatively controlled according to the discharge power and the required power, including: if the discharge power of the power battery is greater than the current required power, the power battery output power is controlled; if the discharge power of the power battery is less than or equal to the current required power and the current required power is less than a first preset threshold, the fuel cell and power battery output power of the vehicle are cooperatively controlled; if the current required power is greater than or equal to the first preset threshold, the hydrogen internal combustion engine, fuel cell, and power battery output power of the vehicle are cooperatively controlled.

[0037] Among them, the first preset threshold can be set according to actual needs and is not specifically limited.

[0038] It can be understood that the embodiment of the present application can determine the corresponding output strategy according to the discharge power of the power battery, the current required power and the size of the first preset threshold, so as to comprehensively improve the working efficiency of the system and reduce the overall cost of the system.

[0039] Specifically, if Figure 2 As shown, assuming that the current demand power is P1 and the discharge power of the power battery is P2, if P1<P2, the fuel cell engine remains in idle or shut down state, the hydrogen internal combustion engine remains in idle or shut down state, and the power demand of the whole vehicle is provided by the power battery; in the idle state, the hydrogen internal combustion engine or the fuel cell maintains minimum operation, usually to keep the system in a state of rapid response at any time, but the power they provide at this time is very low and hardly contributes to the power of the whole vehicle.

[0040] If P2≤P1<M, the fuel cell engine is started, the hydrogen internal combustion engine remains in idle / shutdown state, and the output power of the fuel cell engine is determined according to the discharge power of the power battery.

[0041] If P1≥M, start the fuel cell engine, control the fuel cell engine output power P3=N, start the hydrogen internal combustion engine, and determine the fuel cell engine output power based on the discharge power of the power battery and the fuel cell engine output power.

[0042] In an embodiment of the present application, the vehicle's fuel cell and power battery output power are collaboratively controlled, including: identifying the current state of charge of the power battery; controlling the vehicle's fuel cell and power battery output power according to the current state of charge of the power battery, the discharge power of the power battery and the current required power.

[0043] It can be understood that the embodiments of the present application can control the output power of the vehicle's fuel cell and power battery according to the current charge state of the power battery, the discharge power of the power battery and the current required power, so as to comprehensively improve the working efficiency of the system and reduce the overall cost of the system.

[0044] In an embodiment of the present application, the output power of the fuel cell and the power battery of the vehicle is controlled according to the current state of charge of the power battery, the discharge power of the power battery and the current required power, including: if the current state of charge of the power battery is less than a second preset threshold, the output power of the fuel cell is determined according to the discharge power of the power battery and the current required power, and the fuel cell is controlled to output the current required power; if the current state of charge of the power battery is greater than or equal to the second preset threshold and less than the third preset threshold, the fuel cell is controlled to independently output the current required power; if the current state of charge of the power battery is greater than or equal to the third preset threshold, the output power of the fuel cell is calculated according to the discharge power of the power battery and the current required power, and the fuel cell and power battery of the vehicle are collaboratively controlled to jointly output the current required power, wherein the third preset threshold is greater than the second preset threshold.

[0045] Among them, the second preset threshold and the third preset threshold can be set according to actual needs and are not specifically limited.

[0046] It can be understood that the embodiments of the present application can control the output power of the vehicle's fuel cell and power battery based on the current charge state of the power battery, the discharge power of the power battery and the current required power, so as to comprehensively improve the working efficiency of the system and reduce the overall cost of the system.

[0047] Specifically, if Figure 2As shown, if P2≤P1<M, start the fuel cell engine and keep the hydrogen internal combustion engine in idle / shutdown state; if the power battery SOC<A, control the fuel cell engine output power P3=P1-P2 (the power battery is low and needs to be charged, P2 is a negative number); if A≤SOC<B, control the fuel cell engine output power P3=P1; if SOC≥B, control the fuel cell engine output power P3=P1-P2 (the power battery is high and can be discharged, P2 is a positive number), wherein A corresponds to the above-mentioned second preset threshold value, and B corresponds to the above-mentioned third preset threshold value.

[0048] It should be noted that when the power battery is low, the fuel cell engine can supplement the insufficient power of the power battery.

[0049] In an embodiment of the present application, the power output of the vehicle's hydrogen internal combustion engine, fuel cell and power battery are cooperatively controlled, including: controlling the output power of the fuel engine to be a fourth preset threshold; cooperatively controlling the vehicle's hydrogen internal combustion engine, fuel cell and power battery to output the current required power based on the current state of charge of the power battery, the discharge power of the power battery, the output power of the fuel engine and the current required power.

[0050] Among them, the fourth preset threshold can be set according to actual needs and is not specifically limited.

[0051] It can be understood that the embodiments of the present application can control the output power of the fuel engine to maintain a certain power, and coordinately control the vehicle's hydrogen internal combustion engine, fuel cell and power battery to output the current required power according to the current charge state of the power battery, the discharge power of the power battery, the output power of the fuel engine and the current required power, so as to comprehensively improve the working efficiency of the system and reduce the overall cost of the system.

[0052] In an embodiment of the present application, the vehicle's hydrogen internal combustion engine, fuel cell and power battery are collaboratively controlled to output the current required power based on the current state of charge of the power battery, the discharge power of the power battery, the output power of the fuel engine and the current required power, including: if the current state of charge of the power battery is less than a second preset threshold, the output power of the hydrogen internal combustion engine is determined based on the discharge power of the power battery, the output power of the fuel engine and the current required power, and the fuel cell and the hydrogen internal combustion engine are controlled to output the current required power; if the current state of charge of the power battery is greater than or equal to the second preset threshold and less than the third preset threshold, the output power of the hydrogen internal combustion engine is determined based on the output power of the fuel engine and the current required power, and the vehicle's hydrogen internal combustion engine and fuel cell are collaboratively controlled to output the current required power; if the current state of charge of the power battery is greater than or equal to the third preset threshold, the output power of the hydrogen internal combustion engine is calculated based on the discharge power of the power battery, the output power of the fuel engine and the current required power, and the vehicle's fuel cell, hydrogen internal combustion engine and power battery are collaboratively controlled to output the current required power.

[0053] It can be understood that the embodiments of the present application can coordinately control the vehicle's hydrogen internal combustion engine, fuel cell and power battery to output the current required power according to the current charge state of the power battery, the discharge power of the power battery, the output power of the fuel engine and the current required power, so as to comprehensively improve the system's operating efficiency and reduce the overall cost of the system.

[0054] Specifically, if Figure 2 As shown, if P1≥M, start the fuel cell engine and control the fuel cell engine output power P3=N; start the hydrogen internal combustion engine; if the power battery SOC<A, control the hydrogen internal combustion engine output power P4=P1-P3-P2 (the power battery is low and needs to be charged, P2 is a negative number); if A≤SOC<B, control the hydrogen internal combustion engine output power P4=P1-P3; if SOC≥B, control the hydrogen internal combustion engine output power P4=P1-P3-P2 (the power battery is high and can be discharged, P2 is a positive number).

[0055] According to the multi-power source control method for a vehicle proposed in an embodiment of the present application, the current required power of the vehicle and the current state of charge of the power battery are obtained, the output power of the power battery is determined according to the current state of charge of the power battery, and at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery is cooperatively controlled according to the output power of the power battery and the current required power of the vehicle, thereby comprehensively improving the working efficiency of the system and reducing the overall cost of the system, and the applicability is high.

[0056] The following will be combined Figure 2 The multi-power source control method of the vehicle of the present application is described in detail, and the specific steps are as follows:

[0057] Step 1, obtain the current required power P1, obtain the current power battery SOC, and confirm the discharge power P2 of the power battery according to the power battery SOC.

[0058] Step 2: If P1 < P2, the fuel cell engine remains in idle / off state, the hydrogen internal combustion engine remains in idle / off state, and the power required by the vehicle is provided by the power battery.

[0059] If P2≤P1<M, start the fuel cell engine and keep the hydrogen internal combustion engine in idle / shutdown state. If the power battery SOC<A, control the fuel cell engine output power P3=P1-P2 (the power battery is low and needs to be charged, P2 is a negative number). If A≤SOC<B, control the fuel cell engine output power P3=P1. If SOC≥B, control the fuel cell engine output power P3=P1-P2 (the power battery is high and can be discharged, P2 is a positive number).

[0060] If P1≥M, start the fuel cell engine and control the fuel cell engine output power P3=N; start the hydrogen internal combustion engine; if the power battery SOC<A, control the hydrogen internal combustion engine output power P4=P1-P3-P2 (the power battery is low and needs to be charged, P2 is a negative number); if A≤SOC<B, control the hydrogen internal combustion engine output power P4=P1-P3; if SOC≥B, control the hydrogen internal combustion engine output power P4=P1-P3-P2 (the power battery is high and can be discharged, P2 is a positive number).

[0061] Next, the multi-power source control device for a vehicle proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0062] Figure 3 It is a block diagram of a multi-power source control device for a vehicle according to an embodiment of the present application.

[0063] like Figure 3 As shown, the multi-power source control device 10 of the vehicle includes: an acquisition module 110 , a determination module 120 and a control module 130 .

[0064] Among them, the acquisition module 100 is used to obtain the current required power of the vehicle and the current charge state of the power battery; the determination module 200 is used to determine the discharge power of the power battery according to the current charge state of the power battery; the control module 300 is used to coordinately control at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery according to the discharge power and the required power.

[0065] It should be noted that the above explanation of the embodiment of the vehicle multi-power source control method is also applicable to the vehicle multi-power source control device of this embodiment, and will not be repeated here.

[0066] According to the multi-power source control device for a vehicle proposed in the embodiment of the present application, the current required power of the vehicle and the current state of charge of the power battery are obtained, the output power of the power battery is determined according to the current state of charge of the power battery, and at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery is cooperatively controlled according to the output power of the power battery and the current required power of the vehicle, thereby comprehensively improving the working efficiency of the system and reducing the overall cost of the system, and the applicability is relatively high.

[0067] Figure 4 A schematic diagram of the structure of a vehicle provided in an embodiment of the present application.

[0068] like Figure 4 As shown, the vehicle 20 may include: a power battery 210 , a fuel cell 220 , a hydrogen internal combustion engine 230 and a vehicle controller 240 .

[0069] Among them, the hydrogen internal combustion engine outputs power based on the exhaust gas and waste water of the fuel cell, and the vehicle controller, based on the multi-power source control method of the vehicle in the above embodiment, collaboratively controls at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery.

[0070] Specifically, in the fuel cell engine reaction, air is passed into the cathode and hydrogen is passed into the anode. The cathode air and the anode hydrogen generate electricity under the action of the catalyst in the membrane electrode. A large amount of water will be produced during the reaction and accumulate at the cathode and the anode. The cathode air and the anode hydrogen generate electricity under the action of the catalyst in the membrane electrode. Since there is a large amount of nitrogen in the air, the nitrogen will diffuse into the anode through the proton exchange membrane. As time accumulates, the hydrogen concentration at the anode decreases, causing the voltage of the battery stack to decrease.

[0071] During operation, the fuel cell will generate a large amount of water and exhaust gas. This water can be recycled and reused to improve the overall efficiency and resource utilization of the system. The hydrogen internal combustion engine of the present application outputs power based on the exhaust gas and waste water of the fuel cell. The hydrogen internal combustion engine will generate a large amount of heat when working and requires an effective cooling system to maintain a normal operating temperature. At this time, the water generated by the fuel cell can be used for the cooling system to absorb and take away the heat of the engine through circulating water; the hydrogen internal combustion engine requires appropriate humidity during the combustion process to improve the combustion efficiency. At this time, the water generated by the fuel cell can be used to humidify the air entering the hydrogen internal combustion engine to ensure the optimal humidity conditions during the combustion process; the water generated by the fuel cell can be decomposed into hydrogen and oxygen again through electrolysis, providing an additional source of hydrogen for the system.

[0072] According to the vehicle proposed in the embodiment of the present application, the hydrogen internal combustion engine outputs power based on the exhaust gas and waste water of the fuel cell, and uses the vehicle controller to collaboratively control at least one output power of the vehicle's fuel cell, hydrogen internal combustion engine and power battery, thereby comprehensively improving the system's operating efficiency and reducing the overall cost of the system, with high applicability.
