new energy vehicles are more discussed now, so what is the fuel of new energy vehicles? As we all know, oil belongs to non renewable resources, and the harm of exhaust gas from fuel vehicles to the environment cannot be underestimated. Then the development of new energy vehicles has become a trend, how much do you know?
What new energy vehicles use as fuel: Development
In the long history of human beings, the two transportation and energy reforms have brought great changes to human production and life. The first was the steam engine era in the 1860s, which triggered the industrial revolution with coal and steam engine and made European countries become the world economic powers. The second was the 1870s, when oil and internal combustion engine replaced coal and steam engine, which contributed to the rapid development of American economy It has brought mankind into the economic system and material prosperity based on oil;
Our era is facing the third change of transportation energy. It started from the energy crisis in the 1970s. It will replace oil and internal combustion engine with electric power and power battery, and bring mankind into the era of clean energy. Combined with China's energy resources and the development trend of international automobile technology, it is predicted that by 2025, the ownership of traditional gasoline vehicles in China will decline by less than 50%, New energy vehicles will be popular.
New energy vehicle refers to the vehicle with advanced technical principle, new technology and new structure, which uses unconventional vehicle fuel as power source (or conventional vehicle fuel and new vehicle power device), integrates advanced technology in vehicle power control and drive. New energy vehicles include pure electric vehicles, incremental electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, other new energy vehicles, etc.
Blade Electric Vehicles
The pure electric vehicles (Bev) is a kind of vehicle which uses a single battery as the power source of energy storage. It uses the battery as the power source of energy storage, provides the electric energy to the motor through the battery, drives the motor to run, thus promotes the vehicle to run.
Hybrid electric vehicle (HEV) is a vehicle whose driving system is composed of two or more single driving systems which can run at the same time. The driving power of the vehicle is provided by a single driving system or multiple driving systems according to the actual driving state of the vehicle. Due to the different components, layout and control strategies, hybrid vehicles have many forms.
Fuel cell electric vehicle
Fuel cell electric vehicle (FCEV) is a kind of vehicle driven by the main power source, which uses the electric energy generated by the electrochemical reaction in the fuel cell under the action of hydrogen and oxygen in the air under the catalyst. Fuel cell electric vehicle is essentially a kind of pure electric vehicle, the main difference is that the working principle of power battery is different. Generally speaking, fuel cell converts chemical energy into electrical energy through electrochemical reaction. Hydrogen is generally used as reducing agent and oxygen is used as oxidant for electrochemical reaction. Therefore, most of the earliest developed fuel cell electric vehicles directly use hydrogen fuel. Hydrogen can be stored in the form of liquefied hydrogen, compressed hydrogen or metal hydride.
Hydrogen engine vehicle
Hydrogen engine vehicle is a vehicle with hydrogen engine as power source. Generally, diesel or gasoline is used as the fuel of engine, while gas hydrogen is used as the fuel of hydrogen engine. Hydrogen engine vehicle is a kind of real vehicle which can realize zero emission. It emits pure water, which has the advantages of no pollution, zero emission and rich reserves.
Other new energy vehicles
Other new energy vehicles include those that use super capacitors, flywheels and other efficient energy storage devices. At present, in China, new energy vehicles mainly refer to pure electric vehicles, incremental electric vehicles, plug-in hybrid vehicles and fuel cell electric vehicles.
