What types of new energy vehicles mainly include?

New energy vehicles include hybrid vehicles, pure electric vehicles, fuel cell vehicles, hydrogen-powered vehicles, pneumatic vehicles, methanol vehicles, flywheel energy storage vehicles and supercapacitors.

1. Hybrid electric vehicle. Hybrid power refers to those vehicles that use traditional fuels and are equipped with motors and engines to improve low-speed power output and fuel consumption. According to different fuel types, it can be divided into gasoline hybrid and diesel hybrid.

2. Pure electric vehicles. Pure electric vehicles are mainly driven by electricity. Most vehicles are directly driven by motors, some are installed in the engine compartment, and some directly use wheels as the rotors of four motors. The difficulty lies in energy storage technology.

3. Fuel cell vehicles. Fuel cell vehicles refer to vehicles that use hydrogen, methanol and other fuels. As fuel, electricity is generated by chemical reaction and driven by motor. The energy of the battery is directly converted into electric energy through the chemical action of hydrogen and oxygen, and no harmful products are produced, so it is a pollution-free vehicle;

4. Hydrogen powered cars. Hydrogen-powered vehicles are truly zero-emission vehicles, which emit pure water. It has the advantages of no pollution, zero emission and abundant reserves. Therefore, hydrogen-powered cars are the most ideal substitutes for traditional cars.

5. Gas cars. The fuel gas has the advantages of single component, high purity, uniform mixing with air, complete combustion, low emission of carbon monoxide and particulate matter, and good low-temperature starting and running performance of the engine. Its disadvantages are that the transportation performance is worse than that of liquid fuel, the volumetric efficiency of the engine is low, the ignition delay time is long and the power performance is reduced.

6. Methanol cars. Cars that use methanol instead of petroleum fuel;

7. Flywheel energy storage vehicle. The inertial energy storage of the flywheel is used to store the residual energy when the engine is not fully loaded and the energy when the vehicle slows down on a long downhill, and feed it back to the generator to generate electricity, thereby driving or accelerating the rotation of the flywheel. As an auxiliary in hybrid electric vehicle, it has the advantages of improving energy utilization efficiency, light weight, high energy storage, fast energy input and output response, less maintenance and long service life. But its disadvantage is high cost, and automobile steering will be affected by flywheel gyro effect.

8. Super capacitor car. Supercapacitor is a capacitor based on the principle of electric double layer. Under the action of the electric field generated by the charges on the two plates of the supercapacitor, opposite charges are formed at the interface between the electrolyte and the electrode to balance the electric field inside the electrolyte. This positive charge and negative charge are arranged in opposite positions, and there is a very short gap between them at the interface of two different phases. This charge distribution layer is called an electric double layer, so the capacitance is very large.
