An electric vehicle refers to a vehicle that's hopped-up by Associate in Nursing on-board power offer and driven by a motor to drive wheels, and meets the wants of road traffic and safety regulations.

The advantages of electrical vehicles are:

It does not emit harmful gases that pollute the atmosphere. Even if the power consumption is converted into the emission of power plants, other pollutants besides sulfur and particulates are also significantly reduced. Since power plants are mostly built far away from densely populated cities, it is harmful to humans. Fewer, and the power plant is stationary, concentrated emissions, it is easier to remove all kinds of harmful emissions, and related technologies are also available. Since electricity can be obtained from a variety of primary energy sources, such as coal, nuclear power, water power, wind power, etc., people's worries about the depletion of oil resources are relieved. electrical vehicles also can alter use of the excess electricity at nighttime once the electricity is low for charging, in order that power generation and instrumentation will be totally used day and night, greatly up its economic benefits.

Relevant studies have shown that the same crude oil is crudely refined, sent to power plants for power generation, charged into batteries, and then powered by batteries. Its energy utilization efficiency is higher than that of refined into gasoline and then powered by gasoline engines, so it is conducive to saving energy. And to reduce carbon dioxide emissions, it is these advantages that make the research and application of electric vehicles a "hot spot" in the automotive industry.
