History of the electric vehicle

BEVs were among some of the earliest automobiles — electric vehicles predate gasoline and diesel. Between 1832 and 1839 (the exact year is uncertain), Scottish businessman Robert Anderson invented the first crude electric carriage. Professor Sibrandus Stratingh of Groningen, the Netherlands, designed the small-scale electric car, built by his assistant Christopher Becker in 1835.

The improvement of the storage battery, by Frenchmen Gaston Plante in 1865 and Camille Faure in 1881, paved the way for electric vehicles to flourish. France and Great Britain were the first nations to support the widespread development of electric vehicles.
Just prior to 1900, before the pre-eminence of powerful but polluting internal combustion engines, electric automobiles held many speed and distance records. Among the most notable of these records was the breaking of the 100 km/h (60 mph) speed barrier, by Camille Jenatzy on April 29, 1899 in his 'rocket-shaped' vehicle Jamais Contente, which reached a top speed of 105.88 km/h (65.79 mph).

BEVs, produced by Anthony Electric, Baker, Detroit, Edison, Studebaker, and others during the early 20th Century for a time out-sold gasoline-powered vehicles. Due to technological limitations and the lack of transistor-based electric technology, the top speed of these early electric vehicles was limited to about 32 km/h (20 mph). These vehicles were successfully sold as town cars to upper-class customers and were often marketed as suitable vehicles for women drivers due to their clean, quiet and easy operation. Electrics did not require hand-cranking to start.

The introduction of the electric starter by Cadillac in 1913 simplified the task of starting the internal combustion engine, formerly difficult and sometimes dangerous. This innovation contributed to the downfall of the electric vehicle, as did the mass-produced and relatively inexpensive Ford Model-T, which had been produced for four years, since 1908.[4] Internal-combustion vehicles advanced technologically, ultimately becoming more practical than — and out-performed — their electric-powered competitors.

Another blow to BEVs was the loss of Edison's direct current (DC) electric power transmission system in the War of Currents. This deprived BEV users of a convenient source of DC electricity to recharge their batteries. As the technology of rectifiers was still in its infancy, changing alternating current to DC required a costly rotary converter.
Battery electric vehicles became popular for some limited range applications. Forklifts were BEVs when they were introduced in 1923 by Yale and some battery electric fork lifts are still produced. BEV golf carts have been available for many years, including early models by Lektra in 1954. Their popularity led to their use as neighborhood electric vehicles and expanded versions became available which were partially "street legal".

By the late 1930s, the electric automobile industry had completely disappeared, with battery-electric traction being limited to niche applications, such as certain industrial vehicles.
The 1947 invention of the point-contact transistor marked the beginning of a new era for BEV technology. Within a decade, Henney Coachworks had joined forces with National Union Electric Company, the makers of Exide batteries, to produce the first modern electric car based on transistor technology, the Henney Kilowatt, produced in 36-volt and 72-volt configurations. The 72-volt models had a top speed approaching 96 km/h (60 mph) and could travel nearly an hour on a single charge. Despite the improved practicality of the Henney Kilowatt over previous electric cars, it was too expensive, and production was terminated in 1961. Even though the Henney Kilowatt never reached mass production volume, their transistor-based electric technology paved the way for modern EVs.
After California indicated that it would kill its ZEV Mandate, Toyota offered the last 328 RAV4-EV for sale to the general public during six months (ending on Nov. 22, 2002). All the rest were only leased, and with minor exceptions those models were withdrawn from the market and destroyed by manufacturers (other than Toyota). Toyota not only supports the 328 Toyota RAV4-EV in the hands of the general public, still all running at this date, but also supports hundreds in fleet usage. From time to time, Toyota RAV4-EV come up for sale on the used market, at prices that have ranged up to the mid 60 thousands of dollars. These are highly prized by solar homeowners who wish to charge their cars from their solar electric rooftop systems.
As of July, 2006, there are between 60,000 and 76,000 low-speed, battery powered vehicles in use in the US, up from about 56,000 in 2004 according to Electric Drive Transportation Association estimates
