Problems solved by technology
However, excessive pursuit of these unrealistic performances at this stage will lead to high cost of fuel cell electric vehicles and cause great difficulties for the industrialization of fuel cell electric vehicles
The high cost is also the fundamental reason why the market is skeptical about fuel cell electric vehicle technology

Embodiment Construction
[0018] The present invention proposes an electric-electric hybrid vehicle drive system and its control method, including a fuel cell 1, a lithium-ion battery 2, a power management unit 3, an electronic control unit 4, a drive axle 9, an accelerator pedal 10, and a shifting device 11 and charging interface 12. Among them, the electronic control unit 4 centrally controls the running state of the whole vehicle. The electronic control unit 4 collects the signals input by the accelerator pedal 10 and the shifting device 11, and coordinates the fuel cell 1 and the lithium battery through the power management unit 3 according to the real-time running state of the vehicle. The working state of the ion battery 2 controls the operation of the pre-drive motor 5, thereby constituting the driving system of the hybrid electric vehicle. The present invention can also cooperate with a larger power front drive motor 5 and a smaller power rear drive motor 7 to drive the vehicle in coordination....

The invention discloses an electrical-electrical hybrid vehicle drive system. The electrical-electrical hybrid vehicle drive system is characterized in that the output terminal of a power supply managing unit is connected to a front-arranged drive motor, and the input end is connected to a fuel cell, a lithium ion battery, a charging interface and an electronic control unit; the input end of the electronic control unit is connected with an accelerator pedal and a shift device. By means of the structure, the electrical-electrical hybrid vehicle drive system has the advantages that requirements on the power of the fuel cell is lowered, a 10 kilowatt fuel cell and a 10 kwh lithium ion battery are matched to serve as the power source, cost is low, and vehicle safety is improved; power output of the vehicle can be adjusted in real time according to different vehicle conditions, and endurance is high; an existing electrical vehicle can be optimized, and the electrical-electrical hybrid vehicle drive system is adaptable to wide-range promotion.
Description
technical field [0001] The invention relates to the field of design and manufacture of hybrid vehicles, in particular to an electric-electric hybrid vehicle drive system and a control method thereof. Background technique [0002] At present, major automobile manufacturers at home and abroad are using pure fuel cell solutions to design and manufacture fuel cell vehicles. Each fuel cell vehicle is equipped with a fuel cell of more than 40 kW or even 100 kW, and the design of fuel cell vehicles is carried out according to the design ideas of traditional internal combustion engine vehicles. Blind pursuit of the power of the car, unrealistically high maximum speed (for example, the maximum speed of fuel cell vehicles is required to be greater than 160 kilometers, etc.), too high acceleration performance (requires fuel cell vehicles, the acceleration time of 100 kilometers is less than 12 seconds, etc. ). However, excessive pursuit of these unrealistic performances at this stage ...
