Development of automobile energy.

Without the competition of enterprises, there would be no industrial progress. Looking back on the century-long history of global automobiles is not only a history of market competition, but also a history of technological innovation. Today, Dr. Cha will introduce the development and changes of automobile energy.

As we all know, there are many kinds of automobile energy at present, mainly including gasoline, diesel, natural gas, oil-electricity hybrid, pure electric, plug-in hybrid and extended range. However, the changes of these energy sources have experienced the development history of 130 years.

Many people think that the history of automobile development began with Karl Benz's invention of the first fuel car in 1885, but it is not. The predecessor of the automobile should be the steam engine automobile invented by 1870, from which the word "automobile" came.

188 1 year, with the use of lead-acid batteries, lead-acid battery-charged electric vehicles were born, with a maximum cruising range of 40 kilometers, which have been applied in urban commuting, short-distance transportation and other practical markets.

65438-0885 Since Ben Ci invented the first fuel car, due to the continuous progress of internal combustion engine technology and constant competition, the car entered the era of three pillars: steam locomotive, electric vehicle and fuel car. With the passage of time, after 1925, due to the low technical efficiency of steam engines, the high cost of electric vehicles and the backward technical development, the market scale of the two companies has been shrinking and gradually faded out of the historical stage, and automobile energy has started the stage where fuel vehicles dominate.

Since 1960s, energy has entered the development stage of electrification, new energy and even intelligence. Because some industrialized cities, such as California and London, suffered from smog caused by automobile exhaust, 1973, the first oil crisis, the trend of low displacement, light weight and electrification began to affect the automobile field, and the development of related materials, power electronics, secondary batteries and fuel cells also made electric vehicles begin to receive renewed attention.

1990 due to the lagging development of battery technology, tram manufacturers are forced by market pressure to start developing hybrid vehicles to overcome the problems of short battery and cruising range.

In the new century, battery technology has finally achieved a new breakthrough, the density and endurance have been greatly improved, and the motor power is not inferior to that of low-displacement fuel vehicles. Countries began to vigorously promote environmentally-friendly trams, and China vigorously promoted the technical development and product landing of new energy vehicles, becoming the country with the highest number of new energy vehicles and output in the world.

I believe that, in everyone's opinion, whether veterans or fresh troops, only by taking the new development concept as the guide, taking the new energy renewal as the main line and mastering the core key technologies can they be more competitive in today's market and win new competitive advantages.
