Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Electric Vehicle shopping experience:
1. Compare - without doubt the biggest advantage that the Electric Vehicle offers shoppers today is the ability to compare thousands of Electric Vehicle at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Electric Vehicle? Wrong! If the Electric Vehicle is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Electric Vehicle then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Electric Vehicle? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Electric Vehicle and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Electric Vehicle wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Electric Vehicle then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Electric Vehicle site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Electric Vehicle, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Electric Vehicle, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
drawing current from a single overhead wire, returning current through the rails and ground, taking power through a
Pantograph (rail)An
electric vehicle, or EV, is a vehicle with one or more
electric motors for
propulsion. The motion may be provided either by
wheels or propellers driven by rotary motors, or in the case of tracked vehicles, by
linear motors.
The
energy used to propel the vehicle may be obtained from several sources, some of them more ecological than others:
- from an on-board rechargeable energy storage system (RESS), called Full Electric Vehicles (FEV):
- from a direct connection to land-based generation plants, as is common in electric trains and trolleybus (See also : third rail and conduit current collection)
- from both an on-board rechargeable energy storage system and a direct continuous connection to land-based generation plants for purposes of on-highway recharging with unrestricted highway range.
- from both an on-board rechargeable energy storage system (rechargeable energy storage system) and a fueled propulsion power source (internal combustion engine): hybrid vehicle (as in a diesel-electric locomotive ), including plug-in hybrid
- from renewable sources such as wind energy and solar car
- generated on-board using a fuel cell: fuel cell vehicle
- generated on-board using nuclear energy, on nuclear submarines and aircraft carriers
Electric vehicles can include
electric airplanes, electric boats, and electric motorcycles and scooters.
History
and a 1914 Detroit Electric, model 47 (courtesy of the
National Museum of American History)Electric motive power started with a small railway operated by a miniature electric motor, built by
Thomas Davenport in
1835. In
1838, a Scotsman named
Robert Davidson built an electric locomotive that attained a speed of four miles an hour. In England a patent was granted in 1840 for the use of rails as conductors of electric current, and similar American patents were issued to
Lilley and Colten in
1847. History of Railway Electric Traction
Between 1832 and 1839 (the exact year is uncertain), Robert Anderson (businessman) of
Scotland invented the first crude electric carriage, powered by non-rechargeable Primary cells. Inventors - Electric Cars (1890 - 1930)
By the 20th century, electric cars and rail transport were commonplace, with commercial electric automobiles having the majority of the market. Over time their general-purpose commercial use reduced to specialist roles, as Electric platform truck,
forklift trucks, tow tractors and urban delivery vehicles, such as the iconic United Kingdom
milk float.
Electrified trains were used for
coal transport as the motors did not use precious
oxygen in the mines.
Switzerland's lack of natural fossil resources forced the rapid electrification of
Rail transport in Switzerland. One of the earliest
rechargeable batteries -the Nickel-iron battery - was favored by Edison for use in electric cars.
Electric vehicles were among the earliest automobiles, and before the preeminence of light, powerful
internal combustion engines, electric automobiles held many vehicle land speed and distance records in the early 1900s. They were produced by Baker Electric,
Columbia Automobile Company,
Detroit Electric, and others and at one point in history out-sold gasoline-powered vehicles.
In the 1930s, National City Lines, which was a partnership of General Motors,
Firestone Tire and Rubber Company, and
Standard Oil of California purchased many electric
tram networks across the country to dismantle them and replace them with GM buses. The partnership was convicted for this
General Motors streetcar conspiracy, but the ruling was overturned in a higher court. Electric tram line technologies could be used to recharge
BEVs and PHEVs on the highway while the user drives, providing virtually unrestricted driving range. The technology is old and well established (see : Conduit current collection, Nickel-iron battery). The infrastructure has not been built.
crushed by General Motors only 5 years after production
In January of 1990, General Motors' President introduced its EV concept two-seater, the "Impact," at the Los Angeles Auto Show. That September, the California Air Resources Board mandated major-automaker sales of EVs, in phases starting in 1998. From 1996 to 1998 GM produced 1117 EV1s, 800 of which were made available through 3-year leases.
Chrysler, Ford, GM, Honda, Nissan and Toyota also produced limited numbers of EVs for Califonia drivers. In 2003, upon the expiration of General Motors EV1 leases, GM crushed them. The crushing has variously been attributed to 1) the auto industry's successful Federal Court challenge to California's
Zero-emissions vehicle mandate, 2) a federal regulation requiring GM to produce and maintain spare parts for the few thousands EV1s and 3) the success of the Oil and Auto industries' media campaign to reduce public acceptance of electric vehicles.
A movie made on the subject in 2005-2006 was titled Who Killed the Electric Car? and released theatrically by
Sony Pictures Classics in 2006. The film explores the roles of
automobile manufacturers,
oil industry, the US government,
battery (electricity), Hydrogen (car), and
consumers, and each of their roles in limiting the deployment and adoption of this technology.
Honda, Nissan and Toyota also repossessed and crushed most of their EVs, which, like the GM EV1s, had been available only by closed-end lease. After public protests, Toyota sold 200 of its RAV EVs to eager buyers; they now sell, five years later, at over their original forty-thousand-dollar price.
Energy sources
with return through the traction rails
Chemical energy is a common independent energy source. Chemical energy is converted to electrical energy, which is then regulated and fed to the drive motors. Chemical energy is usually in the form of diesel or petrol (gasoline). The liquid fuels are usually converted into electricity by an
electrical generator powered by an internal combustion engine or other
heat engine. This approach is known as
diesel-electric or gasoline-electric
hybrid vehicle locomotion. These engines still produce
greenhouse gases, though typically less than conventional petroleum vehicles Current UK vehicle CO2 output comparison USA EPA Green Vehicle Guide, and can be combined with
regenerative braking systems for more efficiency.
Nowadays
Battery (electricity), ultracapacitor and
flywheel energy storage are on-board
rechargeable energy storage system (RESS). By avoiding an intermediate mechanical step, the
energy conversion efficiency is dramatically improved over the chemical-thermal-mechanical-electrical-mechanical process already discussed. This is due to the higher
Energy efficiency through directly oxidizing the fuel and by avoiding several unnecessary energy conversions. Furthermore, electro-chemical batteries conversions are easy to reverse, allowing electrical energy to be stored in chemical form.
Another form of chemical to electrical conversion is fuel cells, projected for future use.
For especially large electric vehicles, such as
submarines, the chemical energy of the diesel-electric can be replaced by a nuclear reactor. The nuclear reactor usually provides heat, which drives a steam turbine, which drives a generator, which is then fed to the propulsion. This energy produces
nuclear waste and nuclear risk.
Electric motor
The power of a vehicle electric motor, as in other vehicles, is measured in kW. 100 kW is roughly equivalent to 134
horsepower.
Large-scale electric transport: energy and motors
uses two overhead wires to provide electrical current supply and return to the power sourceMost large electric transport systems are powered by stationary sources of electricity that are directly connected to the vehicles through wires. Due to the extra infrastructure and difficulty in handling arbitrary travel, most directly connected vehicles are owned publicly or by large companies. These forms of transportation are covered in more detail in
metros, trams, electric locomotives, and trolleybuses.
In the systems above motion is provided by a
rotary electric motor. However, it is possible to "unroll" the motor to drive directly against a special matched track. These
linear motors are used in maglev trains which float above the rails supported by magnetic levitation. This allows for almost no rolling resistance of the vehicle and no mechanical wear and tear of the train or track. Levitation and forward motion are two independent effects; the forward motive force normally requires external power, although some types, such as Inductrack, achieve levitation at low speeds without any. In addition to the high-performance control systems needed, Railroad switch and curving of the tracks becomes difficult with linear motors, which to date has restricted their operations to high-speed point to point services.
Advantages of electric vehicles
Electric motors are mechanically very simple, and release almost no air pollutants at the place where they are operated.
Electric motors often achieve 90%
energy conversion efficiency over the full range of speeds and power output and can be precisely controlled. They can also be combining with
regenerative braking systems that have the ability to convert movement energy back into stored electricity. This can be used to reduce the wear on brake systems (and consequent brake pad dust) and reduce the total energy requirement of a trip, especially effective for start-and-stop city use.
They can be finely controlled and provide high torque from rest, unlike
internal combustion engines, and do not need gears to match power curves. This removes the need for
Transmission (mechanics)es and
torque converters.
Another advantage is that electric vehicles typically have less
vibration and
noise pollution than a vehicle powered by an internal combustion engine, whether it is at rest or in motion.
Issues regarding electric vehicles
Although electric vehicles have few direct emissions, all rely on energy created through
electricity generation which will emit pollution unless it is from a renewable energy source. If a large proportion of private vehicles were to convert to plug-in electricity, the existing powerplant infrastructure would be nearly sufficient, but there would still be a significant need for additional resources (and emissions) in generation and transmission, assuming most charging occurred overnight using the most efficient off-peak
base load sourceshttp://www.pnl.gov/news/release.asp?id=204.
Electromagnetic radiation from high performance electrical motors has been claimed to be associated with some human ailments. Electric motors can be shielded within a metallic Faraday's cage, but this adds weight to the vehicle and it is not conclusive that all electromagnetic radiation can be contained.
Issues with batteries
prototypes. Newer Li-poly cells provide up to 130 Wh/kg and last through thousands of charging cycles.
Many types of EV use batteries, which have an environmental impact through their construction, use, disposal or recycling. Common batteries are expensive and have a shorter life than the vehicle itself, typically needing replacement every 3 years.
Despite the higher
energy efficiency, electro-chemical vehicles have been beset by a technical issue which has prevented them from replacing the more cumbersome heat engines: energy storage. Fuel cells are fragile, sensitive to contamination, and require external reactants such as hydrogen. Batteries currently used are either not mass-produced, leading to high per-unit prices, or end up being a significant (25%-50%) portion of the final vehicle mass, in the case of conventional lead-acid technology. Both have lower Energies per unit mass and
Specific power than petroleum fuels.
The efficiency and storage capacity of the current generation of common deep cycle lead acid batteries decreases with lower temperates, and diverting power to run a heating coil reduces efficiency and range by up to 40%. In the New York City metropolitan area, the running costs of an electric car using standard marine lead-acid batteries, charged only from the mains, has been calculated to cost about 3 times more than a conventional compact gasoline car.Recent advances in battery efficiency, capacity, materials, safety, toxicity and durability are likely to allow these superior characteristics to be applied in car-sized EVs.
Charging and operation of batteries typically results in the emission of hydrogen, oxygen and
sulfur, which are naturally occurring and normally harmless. Early
Citicar owners discovered that, if not vented properly, unpleasant sulfur smells would leak into the cabin immediately after charging.
Incentives
USA
Qualifying electric vehicles purchased new are eligible for a one-time federal tax credit that equals 10% of the cost of the vehicle up to $4,000, provided under Section 179A of the Energy Policy Act of 1992; it was extended through 2007 by the Working Families Tax Relief Act of 2004.
A
tax deduction of up to $100,000 per location is available for qualified electric vehicle recharging property used in a trade or business.

European Union
Directive 2006/32/EC of the European Parliament and of the Council of 5 April 2006 on Efficient energy use and energy services includes measures to promote efficient vehicles.
AVERE has a a table summarizing the taxation and incentives for these vehicles in the different European countries, related to subsidy, reduction of VAT and other taxes, insurance facilities, parking and charging facilities (including free recharging on street or in the parkings), EV imposed by law and banned circulation for petroleum cars, permission to use bus
lanes and toll free on
highways, between others. http://www.avere.org/state_subsidies.pdf
Estimated number of electric vehicles
The
Energy Information Administration (EIA) estimates that were 55,852 Full-Electric Vehicles (FEV) in 2004, with an annual growth rate of 39.1 % (excluding in this estimation electric hybrids). http://www.eia.doe.gov/cneaf/alternate/page/datatables/aft1-13_03.html
Future
Battery Electric Car with 370 km/h top speed and 200 km range car increased from 17% in 2005 to 26% in 2006.
Several start-up companies, like
Tesla Motors and
Phoenix Motorcars, will have powerful battery-electric vehicles available to the public in 2008. Battery and energy storage technology is advancing rapidly. Electric cars are perfectly useful as second household vehicle for usual short and medium distance trips of 100 to 250 miles per charge. The range issue will be improved by technologies such as
Plug-in hybrid electric vehicles which are capable of using traditional fuels for unlimited range.
General Motors is working on a concept car, the plug-in hybrid
Chevrolet Volt that uses a small internal combustion engine hooked to an
electrical generator to resupply the
battery (electricity). They call it an electric vehicle with a "range extender" that can extend the range up to 640 miles.
Improved long term energy storage and nano batteries
There have been several developments which could bring electric vehicles outside their current fields of application, as scooters, golf cars, neighborhood vehicles, in industrial operational yards and indoor operation. First, advances in Lithium ion battery, in large part driven by the consumer electronics industry, allow full-sized, highway-capable electric vehicles to be propelled as far on a single charge as conventional cars go on a single tank of gasoline. Lithium batteries have been made safe, can be recharged in minutes instead of hours, and now last longer than the typical vehicle. The production cost of these lighter, higher-capacity lithium batteries is gradually decreasing as the technology matures and production volumes increase.
Introduction of Battery Management and Intermediate Storage
Another improvement was to decouple the electric motor from the battery through electronic control while employing
ultra-capacitors to buffer large but short power demands and regenerative braking energy. The development of new cell types combined with intelligent cell management improved both weak points mentioned above. The cell management involves not only monitoring the health of the cells but also a redundant cell configuration (one more cell than needed). With sophisticated switched wiring it is possible to condition one cell while the rest are on duty.
