Tesla electric vehicles are a rage these days. The smallest Tesla battery capacity that comes with Model 3 can last up to 262 miles. The highest range a Tesla car offers is 405 miles on a single charge, as of now, in 2023. There was a time when Tesla cars were a status symbol, but an increasing number of people are opting for electric vehicles due to their concerns for the environment.

Presented below is a brief outline of the historical evolution of electric vehicles and electric motors.

History of Electric Vehicles

• Anyos Jedlik built the first crude but viable electric motor, which used a stator, rotor, and commutator in 1827; and the next year he used it to power a small car.
• The first known electric locomotive was built in 1837, in Scotland by chemist Robert Davidson of Aberdeen. It was powered by galvanic cells (batteries).
• A patent for the use of rails as conductors of electric current was granted in England in 1840, and similar patents were issued to Lilley and Colten in the United States in 1847.
• The first battery rail car was used in 1887 on the Royal Bavarian State Railways.
• In 1959, American Motors Corporation (AMC) and Sonotone Corporation announced a joint research effort to consider producing an electric car powered by a “self-charging” battery.
• At the 1990 Los Angeles Auto Show, General Motors President Roger Smith unveiled the GM Impact electric concept car, along with the announcement that GM would build electric cars for sale to the public.
• The passage of the Electric and Hybrid Vehicle Research, Development and Demonstration Act of 1976 in the US provided government incentives for development of electric vehicles in the US.
• California electric car maker Tesla Motors began development in 2004 on the Tesla Roadster, which was first delivered to customers in 2008.
• The Roadster was the first highway legal serial production all-electric car to use lithium-ion battery cells, and the first production all-electric car to travel more than 320 km (200 miles) per charge.
• The Nissan Leaf, introduced in Japan and the United States in December 2010, became the first modern all-electric, zero tailpipe emission five door family h
• In March 2020 the Tesla Model 3 passed the Nissan Leaf to become the world’s all-time best-selling electric car, with more than 500,000 units delivered.
