The principle of wind power generator is to use wind power to generate electricity and connect batteries with the principle of fan. This kind of car can be charged while driving, and can also use wind power to provide power for the car when parking, which truly realizes energy saving and environmental protection. Windmills are mainly driven by wind and kites. Germany was the first country to develop this kind of car. This kind of windmill is mainly driven by wind and kites. It is worth mentioning that in order to drive the car better, the body adopts lightweight design, carbon fiber body and lightweight wheel hub design. It is worth mentioning that, depending on the wind direction, the top speed of this car can reach 88 km/h, and the main power of wind energy vehicles comes from lithium batteries. When the car is not in use, it can be charged by the portable wind generator, which can make maximum use of natural resources to provide power for the car. Principle of wind power generation: Wind power generation converts kinetic energy generated by wind into mechanical energy, and then converts mechanical energy into electrical energy. Wind turbine is mainly composed of nose, rotor, tail and blades. Generally speaking, wind power generation is an advanced technology, which can make maximum use of resources.
