What is the power source of new energy vehicles?

The new energy vehicle refers to an automobile that uses unconventional vehicle fuel as the power source (or conventional vehicle fuel and new vehicle power device), integrates the advanced technology of vehicle power control and driving, and has advanced technical principles, new technologies and new structures.

New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles and so on.

On June 5438+ 10, 2020, the executive meeting of the State Council passed the development plan of new energy automobile industry. The plan shows that from 20021,vehicles in public transportation, rental, logistics and distribution will be added or updated in the national ecological civilization experimental zone and key areas for air pollution prevention and control, and the proportion of new energy vehicles will not be less than 80%.

The development stage of new energy vehicles;

The first stage: the birth of electric vehicles. 1834 The first battery car invented by Thomas Davenport in England was the earliest electric car in the world.

At the beginning of the 20th century, electric vehicles, internal combustion engines and steam engines each accounted for one-third of the American automobile market. 19 10 years, with the large-scale assembly line production of diesel locomotives, the cost has been greatly reduced. However, due to the short cruising range and imperfect infrastructure such as charging stations, electric vehicles once withdrew from the market.

The second stage: electric vehicles regain their attention. In the 1960s, the US government paid more attention to electric vehicles because tens of millions of cars caused serious air pollution.

In the early 1970s, after the oil embargo crisis of the Organization of Petroleum Exporting Countries, the price of gasoline soared, and the interest in electric vehicles in the West became more intense. The government has increased investment in electric vehicle research and development, and various places have established R&D bases, which has led to the arrival of the second round of electric vehicle research and development climax. ?

The third stage: the development of other vehicles such as hybrid power. With the improvement of people's understanding of sustainable development, more and more well-known companies have invested in the research and development of hybrid and pure electric vehicles.

With the increasing number of hybrid vehicle models and the gradual expansion of production and sales scale, many models have shown good energy-saving and environmental protection performance, which indicates that the hybrid vehicle market has matured. Foreign automobile manufacturers designed the world's first hydrogen-powered automobile in 1965, and China successfully built the first hydrogen-powered automobile in 1980.

The fourth stage: the market development of pure electric vehicles. 1994 65438+ 10, the best electric vehicle in the world entered the testing stage. Four years later, the electric vehicle with mature technology entered the trial operation stage. By 1996, the United States has started to manufacture and sell electric vehicles. This is the first electric vehicle launched by a large manufacturing company in modern mass production.

In June 2008, pure electric vehicles ushered in a new spring. The major automobile market countries, including Europe, America and China, have listed pure electric vehicles as the leading direction for future development.
