Electric Vehicles
Overview
Electric vehicles are powered in some capacity by an electric motor, which is used to improve the vehicle's efficiency and reduce its carbon footprint.
While nonelectric vehicles ignite an air and fuel mixture within pistons to turn their wheels, EVs use induction motors to conduct electricity and create a rotating magnetic field that powers the rotor, turning the wheels. EVs store electricity in a lithium-ion battery block weighing an average of 900 pounds under the vehicle.
Before the discovery of the first oil gusher in Texas in 1901 and the release of the Ford Model T in 1908 (which made gas-powered vehicles drastically more affordable and prevalent), electric cars accounted for more than a third of US automobiles and were a status symbol for the wealthy. Today, millions of EVs are sold worldwide, with most major automakers having committed to significantly reducing or eliminating gas-powered vehicles in the next 20 years.
