ELECTRIC CAR








An electric car is an automobile that is propelled by one electric motor or more, using electrical energy stored in batteries or another energy storage device. Electric motors give electric cars instant torque, creating strong and smooth acceleration.
Electric cars were popular in the late 19th century and early 20th century, until advances in internal combustion engine technology and mass production of cheaper gasoline vehicles led to a decline in the use of electric drive vehicles. The energy crises of the 1970s and 1980s brought a short-lived interest in electric cars, though those cars did not reach mass marketing as today's electric cars experience it. Since the mid-2000s, the production of electric cars is experiencing a renaissance due to advances in battery and power management technologies and concerns about increasingly volatile oil prices and the need to reduce greenhouse gas emissions.
