An electric Car is an automobile with an electric motor powered by a system of rechargeable batteries. Electric cars are mechanically simpler and more durable than gasoline-powered cars, and they do not have to exploit nonrenewable resources (natural resources that cannot be replaced). They also produce less pollution than do gasoline-powered cars.
An electric car has a battery, a charger for replenishing the battery's power from an electrical outlet, and a controller. The Controller is connected to the accelerator pedal, for directing the flow of electricity between the battery and motor. Most electric cars use lead-acid batteries, but new types of batteries, including zinc-chlorine, nickel metal hydride, and sodium-sulfur, are being developed. To recharge the batteries, operators plug the car into a 120-volt or 240-volt outlet. The motor of an electric car harnesses the battery's electrical energy by converting it to kinetic energy, or energy that makes the car move. The driver simply switches on the power, selects "Forward" or "Reverse" with another switch, and steps on the accelerator pedal.
