Problems solved by technology

However, it takes about a few seconds from the start of the fuel cell to the output of high-power electric energy, which makes it a problem when it is used as a power source for a car: if the car needs to start running during the start of the fuel cell, the fuel cell cannot provide power to the drive motor. , at this time, it is also necessary to temporarily replace the fuel cell with an auxiliary power source to supply power to the drive motor

Description

technical field [0001] The invention relates to an electric-electric hybrid power system of a fuel cell vehicle, in particular to an electric-electric hybrid power system with an auxiliary power source. Background technique [0002] Energy and the environment are the material basis for the survival and development of human society. The development and utilization of new energy and the protection of the environment are the most important issues facing mankind at present. Over the past two decades, due to the oil crisis and environmental pollution, the development of electric vehicle technology has been promoted and accelerated, and countries around the world have competed in the development and research of electric vehicle technology. Fuel cell vehicles are generally considered to be green and environment-friendly vehicles that can solve energy and emission problems at the same time, and will be the main direction of future automobile development. In the past ten years, fuel...
