The Physics behind the Electric Vehicle It has been estimated that there will be approximately 1200 million motor vehicles by the year 2020. That is almost twice the number of cars that are already traveling on our busy roads. Due to this ever increasing vehicle population, the demand for fuel will continue to increase as well. With the depleting supply of oil already an issue for the U.S. especially, there is a growing interest in alternative energy fuels that can be used to power motor vehicles. Electric vehicles (EV) are one of the cleanest and most environmentally friendly cars available at this point in time. By definition, an electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable or another energy storage device. The electric motors used in these cars gives off instant torque, creating strong and smooth acceleration. Some of the models of EVs have an electric motor for each wheel. Having these four motors not only allows for better propulsion, but also for the use of braking and changing the kinetic energy back into chemical energy in the batteries. The traction that the car gets is also increased with each wheel driving. In some of the EV models the electric motors can be mounted directly inside the mounting for the wheel, which enables a loss of all the moving parts between the motor and the wheel. When there is no axle, differential, or transmission, the EVs have less drivetrain
