An electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable batteries or another energy storage device. Electric motors give electric cars instant torque, creating strong and smooth acceleration. They are also around three times as efficient as cars with an Internal combustion engine. The first electric cars were produced in the 1880s.〔 Electric cars were popular in the late 19th century and early 20th century, until advances in internal combustion engines 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; although, those cars did not reach the mass marketing stage, as is the case in the 21st century. Since 2008, a renaissance in electric vehicle manufacturing has occurred due to advances in batteries and energy management, concerns about increasing oil prices, and the need to reduce greenhouse gas emissions.〔〔''See Introduction''〕 Several national and local governments have established tax credits, subsidies, and other incentives to promote the introduction and adoption in the mass market of new electric vehicles depending on battery size and their all-electric range. Electric cars are significantly quieter than conventional internal combustion engine automobiles. They also do not emit tailpipe pollutants, giving a large reduction of local air pollution, and, in many cases, a large reduction in total greenhouse gas and other emissions (dependent on the method used for electricity generation〔〔). They also provide for independence from foreign oil, which in several countries is cause for concern about vulnerability to oil price volatility and supply disruption.〔〔 ''See Chapter 5: Clean Smart Energy Supply.''〕〔 in ( ''"Plug-in Electric Vehicles: What Role for Washington?"'' )〕 But widespread adoption of electric cars faces several hurdles and limitations, including their current higher purchase cost, patchy recharging infrastructure (other than home charging) and range anxiety (drivers' fear that electric energy stored in the batteries will run out before reaching their destination, due to limited range of most existing electric cars).〔〔 Recharging can take a long time; however, for long distance driving, many cars support fast charging that can give around 80% charge in half an hour, using public fast chargers.〔〔〔(Speedy charging driving a global boom in electric cars )〕 , there are over 30 models of highway legal all-electric passenger cars and utility vans available for retail sales, mainly in the United States, China, Japan, Western European countries. By mid-September 2015, about 620,000 light-duty electric vehicles have been sold worldwide out of total global sales of one million plug-in electric cars sold since 2008.〔 ''Cumulative global sales totaled about 1,004,000 highway legal plug-in electric passenger cars and light-duty vehicles by mid-September 2015, of which, 62% are all-electric cars and vans, and 38% plug-in hybrids.''〕 The world's top selling highway-capable electric car is the Nissan Leaf, released in December 2010 and sold in 46 countries, with global sales of 195,000 units by October 2015,〔 followed by the Tesla Model S, released in June 2012, with about 90,000 units sold by early October 2015.〔 ==Terminology== Electric cars are a variety of electric vehicle (EV). The term "electric vehicle" refers to any vehicle that uses electric motors for propulsion, while "electric car" generally refers to highway-capable automobiles powered by electricity. Low-speed electric vehicles, classified as neighborhood electric vehicles (NEVs) in the United States,〔(【引用サイトリンク】title=US DEPARTMENT OF TRANSPORTATION National Highway Traffic Safety Administration 49 CFR Part 571 Federal Motor Vehicle Safety Standards )〕 and as electric motorised quadricycles in Europe,〔(summary EU proposal for a Regulation on L-category vehicles (two- or three-wheel vehicles and quadricycles) )〕 are plug-in electric-powered microcars or city cars with limitations in terms of weight, power and maximum speed that are allowed to travel on public roads and city streets up to a certain posted speed limit, which varies by country. While an electric car's power source is not explicitly an on-board battery, electric cars with motors powered by other energy sources are generally referred to by a different name: an electric car carrying solar panels to power it is a solar car, and an electric car powered by a gasoline generator is a form of hybrid car. Thus, an electric car that derives its power from an on-board battery pack is a form of battery electric vehicle (BEV). Most often, the term "electric car" is used to refer to battery electric vehicles. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Electric car」の詳細全文を読む スポンサード リンク
