An electric car is an automobile, which is activated by the electric motor(s), using electrical energy stored in batteries or another energy storage device. Electric cars have several potential benefits compared to the conventional automobiles. They are:

• Electric cars include an important reduction of city air pollution. They do not emit harmful tailpipe pollutants from the source of power at the point of operation. In short, Electric cars allow zero tail pipe emissions.
• Electric cars reduced greenhouse gas emissions from the onboard source of power depending on the fuel and technology used for electricity generation to charge the batteries.
Electric cars were popular in the late-19th century and early 20th century.
• The electric smart cars are developed at the smart factory alongside the gas and diesel versions.
