Electric Vehicles
How are they powered and what is their environmental impact? An electric car has a battery, a charger for replenishing the batteries, and power from an electrical outlet. A controller connected to the accelerator pedal is used for directing the flow of electricity between the battery and motor. The older electric batteries were made out of lead acid. The newer batteries are made out of zinc-chlorine, nickel meter			have a power train of gears and shafts joints that transmits power from the motor to the wheels. Electric cars don't have clutches or multispeed transmis

			sions. To go in reverse the power makes the motor go in the opposite direction. They have regenerative braking this acts as a generator. When you step on the brakes the motor acts as the generator and converts the energy caused by the movement back to electricity and stores it in the battery. Electric cars are

How long can a electric powered car last? An electric car can last almost 100 miles or 160 km. They last about 3 hours before they need to be charge again. The Solectria can go over 200 miles on one charge.	Electric cars are more efficient and generally less polluting than the internal-combustion car for a veriety of reasons. First because the
