New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.
pure electric vehicle
Pure electric vehicles (BEV) are vehicles that use a single battery as the energy storage power source. It uses the battery as the energy storage power source to provide electric energy to the electric motor through the battery, driving the electric motor to run, thereby driving the car.
hybrid electric vehicle
Hybrid Electric Vehicle (HEV) refers to a vehicle whose drive system is composed of two or more single drive systems that can operate simultaneously. The driving power of the vehicle is determined by a single drive system or multiple drive systems based on the actual vehicle driving state. Drive system is provided together. Hybrid vehicles come in many forms due to differences in components, arrangements, and control strategies.
fuel cell electric vehicle
Fuel Cell Electric Vehicle (FCEV) uses hydrogen and oxygen in the air under the action of a catalyst. A vehicle driven by electrical energy generated by electrochemical reactions in a fuel cell as the main power source. Fuel cell electric vehicles are essentially a type of pure electric vehicle. The main difference lies in the working principle of the power battery. Generally speaking, fuel cells convert chemical energy into electrical energy through electrochemical reactions. The reducing agent required for the electrochemical reaction generally uses hydrogen, and the oxidant uses oxygen. Therefore, most of the earliest fuel cell electric vehicles developed directly use hydrogen fuel. Hydrogen storage can take the form of liquefied hydrogen, compressed hydrogen or metal hydride hydrogen storage.
hydrogen engine car
A hydrogen engine car is a car that uses a hydrogen engine as its power source. The fuel used by general engines is diesel or gasoline, and the fuel used by hydrogen engines is gaseous hydrogen. Hydrogen engine vehicles are a truly zero-emission vehicle that emits pure water, which has the advantages of no pollution, zero emissions, and abundant reserves.
Other new energy vehicles
Other new energy vehicles include those using high-efficiency energy storage devices such as supercapacitors and flywheels. Currently in my country, new energy vehicles mainly refer to pure electric vehicles, extended range electric vehicles, plug-in hybrid vehicles and fuel cell electric vehicles. Conventional hybrid vehicles are classified as energy-saving vehicles.
