Development prospect of electric vehicles

With the increasingly serious environmental pollution and the continuous promotion of the concept of "low-carbon economy", energy conservation and emission reduction has become a hot issue today. Nowadays, the number of cars is increasing year by year, which not only leads to traffic congestion, but also causes serious environmental pollution. The energy crisis needs to be solved urgently. Under this background, it is an inevitable choice for the sustainable development of automobile industry to develop new energy and energy-saving and environment-friendly cars. The author expounds and summarizes the development status and trend of new energy vehicles and the problems encountered in the development of new energy vehicles in China.

1 Introduction

In China, the concept of new energy vehicles was first put forward in the "863 Plan" in the early 11th Five-Year Plan in 1960s. As soon as the concept of new energy vehicles was put forward, it caused extensive discussion in society and academia, and various manufacturers in the industry also showed high enthusiasm and constantly tried to develop different types of new energy vehicles. So, how is the new energy vehicle defined? At present, the definitions of new energy vehicles are different, and the concepts and classification standards of new energy vehicles are not uniform. This paper will elaborate from the recognized concepts and classifications. New energy vehicles can be divided into broad sense and narrow sense. New energy vehicles in a broad sense refer to all other energy vehicles except internal combustion engines such as gasoline and diesel engines. Including hydrogen vehicles, gas vehicles, fuel cell vehicles and hybrid vehicles, the exhaust emission is relatively low or zero. In a narrow sense, the new energy vehicle refers to the technology that takes unconventional vehicle fuel as the power source and integrates the power control and driving of the vehicle.
