Electric Cars That Electric Drive Cars, Also Known As Electric Drive

 Electric Rover Board Electric cars, that is, electric drive cars, also known as electric drive. Electric cars are divided into AC electric vehicles and DC electric vehicles. Often said the electric car is a battery as a source of energy, through the controller, motor and other components, the electrical energy into mechanical energy to control the current size to change the speed of the vehicle.

  The first electric car was manufactured in 1881, the inventor for the French engineer Gustav Trull, which is a lead-acid battery-powered tricycle it is driven by the DC motor, and today, electric cars Has been a huge change, the type is also varied.

  Economic Contribution Editor

  Electric vehicles in the national economy share is not very high. But it is consistent with the national energy-saving environmental trends, greatly facilitate the short-distance traffic, the most important through the energy and environmental conservation and protection in the national economy plays an important role.

  "China's electric vehicle industry market analysis and analysis report (2015)" shows that in 2010 the size of electric vehicles consumption of 35 billion yuan, [1] 2011 electric vehicle consumption scale of 40 billion yuan, 2012 electric Vehicle consumption scale of 45 billion yuan in 2013, electric vehicle consumption scale of 48.4 billion yuan in 2014, electric vehicle consumption of 52.8 billion yuan.

  Changes in consumer preferences will also affect the changes in the competitive landscape of electric vehicle enterprises. Changes in consumer preferences tend to change as personal income levels change. With the improvement of the economy, the improvement of the consumption level of residents, energy-saving awareness, the quality of electric vehicles also increased with the requirements. The future of electric vehicle industry potential space is huge, 5 years after the industry consumption will exceed 70 billion yuan.

  Shenzhen City Commission, the Municipal Development and Reform Commission on September 8, 2015 jointly issued "on 2015 to be configured to increase the configuration of electric car incremental indicators related to the notice" and other documents, introduced a number of electric cars to encourage the purchase of the New Deal, including the installation of cars 15 yuan rental indicators, dynamic adjustment units and personal indicators of the proportion of distribution, enjoy the first hour of roadside parking free and so on. Shenzhen has also provided a more attractive policy to citizens who have applied for incremental indicators for electric cars, that is, to adjust the individual's policy of applying for incremental quotas for ordinary cars. The original provisions of the "name of the car is not registered in the city," the public can apply for ordinary car indicators, but the latest policy adjustments: "There is only one electric car, and the car is the use of electric cars by Size of the target purchase, and in December 31, 2015 registered on the card "of the public can apply for an ordinary car indicators.

  History of development

  Early

  Electric Rover Board The history of electric cars is earlier than we are now the most common internal combustion engine-driven car. The father of the DC motor The inventor of the Hungarian inventor, the engineer, Anshi Jedelike Jedlik Ányos, first experimented with electromagnetic motion in the laboratory in 1828. American Thomas Davenport Thomas Davenport in 1834 to create the first DC motor-driven electric car. In 1837, Thomas was the first patent in the US motor industry. Between 1832 and 1838, the Scottish Robert Anderson Robert Anderson invented the electric-powered carriage, which was a vehicle that could not be charged with a primary battery. 1838 Scotland Robert Davidson Robert Davidson invented the electric drive train. Today's trams still running on the road were patents that appeared in England in 1840.

  Battery electric car history. The world's first electric car was born in 1881, the inventor for the French engineer Gustav Trull, which is a lead-acid battery-powered tricycle; and in 1873 by the British Robert Davidson A battery for power invention of the electric car, and not included in the international confirmation range. Later appeared on the lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, fuel cells as electricity.

  Medium term

  1860-1920 stage: With the development of battery technology, the use of electric vehicles in the second half of the 19th century in Europe and the United States has been more widely used. In 1859 France's great physicist and inventor, Kaston Plante, invented rechargeable lead-acid batteries.

  At the end of the 19th century to 1920, electric cars in the early car consumption market had more advantages than the internal combustion engine-driven vehicles: no smell, no shock, no noise, no gearshift and low price, which formed a steam, electric and internal combustion engine three Sub-world car market.

  Stagnation period

  1920 - 1990 stage: With the development of Texas oil and internal combustion engine technology to improve the electric car in 1920 after gradually lost its advantage. The car market is gradually replaced by an internal combustion engine. Only in a few cities retain few trams and trolley buses and very limited battery carts (using lead-acid battery packs, used in golf courses, forklifts, etc.).

  The development of electric cars has stagnated for more than half a century. With the flow of oil resources to the market, people almost forget the existence of electric vehicles. Relative to the use of electric vehicles in the technology: electric drive, battery materials, power battery pack, battery management, etc. can not be developed or applied.

  Recovery period

  1990 - present: the ever-decreasing oil resources, the serious pollution of the atmospheric environment, let people re-focus on the electric car. Prior to 1990 to promote the use of electric vehicles mainly to civil society. Such as the establishment of civil society organizations in 1969: World Electric Vehicle Association (World Electric Vehicle Association). The World Electric Vehicle Association organizes professional electric car academic conferences and exhibitions in different countries and regions around the world every year and a half. Electric Vehicle Symposium and Exposition (EVS). Since the beginning of the 1990s the major car manufacturers began to pay attention to the future development of electric vehicles and began to invest capital and technology in the field of electric vehicles. At the Los Angeles Auto Show in January 1990, GM's president introduced Impact pure electric cars to the world. 1992 Ford's use of calcium and sulfur battery Ecostar, 1996 Toyota Motor use nickel-metal hydride batteries RAV4LEV, 1996, France Renault Motor Clio, 1997 Toyota Prius hybrid car off the assembly line, Nissan in 1997 the world's first car Electric car using lithium ion battery Prairie Joy EV, 1999 Honda Motor released, sold hybrid Insight.
