Electric cars are automobiles, which are powered by the electric engine and electric energy. The development of the electric vehicles is a very perspective and important process. Scientists and engineers managed to create electric engines which are no less effective than the ordinary engines used today. It is obvious that electric cars are more ecologically safe and require less energy for work. EVs provide fast acceleration by delivering power instantly to the wheels by providing high torque at low speeds; they give a feel of smooth and quick responsiveness (Technology).
