Electric vehicle subsidy is under threat

The £5,000 subsidy for the purchase of electric vehicles is under threat, according to the Coalition Government's Business Secretary, Vince Cable.
Cable has said that the Government grant could be scrapped as the new administration seeks to cut costs to reduce the national deficit.
The Government ''can't go around waving a chequebook at British industry,'' said Cable, adding that car makers were no longer in an ''emergency situation''.
However, Cable did say that the Government is not planning to walk away from car manufacturers, but will simply be more selective on how it provides support in the future.

EC to ensure electric vehicles charger interoperability

The European Commission has handed on June 2010 a mandate for the development of relevent standards on  common charging system for electric cars, scooters and bicycles to the European Standardisation Organisations bodies, CEN-CENELEC and ETSI. Thanks to this mandate plugs and connectors will use the same standard all across Europe, providing a true European solution independently of brands or countries. The Commission expects that the standard will be ready by mid-2011.
On June 29th 2010,  European Commission Vice-President Antonio Tajani handed a European Commission mandate for the development of the relevant standard for electric vehicles chargers to the President of CEN-CENELEC David Dossett, CEN-CENELEC´s Director General Elena Santiago Cid and European Telecommunications Standards Institute (ETSI) General Assembly Chair John Philips. These new standards are aimed to ensure that all types of electric vehicles and their batteries are charged both safely and easily in all EU Member States.

Washington to build “electric highway”

Washington has launched the nation’s first “electric highway,” a network of electric vehicle recharging stations along Interstate 5. The project will be a partnership between the state’s transportation and commerce departments and is supported by $1.32 in federal Recovery Act infrastructure funding. Once implemented, Washington will have the first border to border highway to offer fast charge technology.
The highway stations will support plug-in electric vehicles along the full 276 miles of I-5 between Washington’s borders north and south. The state estimates that nearly 300,000 electric cars will be on Washington’s roads during the next ten years. Right now, almost half of Washington’s emissions come from standard cars.

Study: 670,000 Fuel Cell Vehicles to be Sold Annually Within 10 Years

The United States will lead the way
Pike Research, a market research and consulting firm that focuses on global clean technology markets, conducted a study that predicts 670,000 fuel cell vehicles (FCVs) will sell annually by 2020.
Some auto companies are still focusing their development on electric vehicles (EVs), and as many other surveys indicate, the growth of electric vehicles are expected to surpassfuel cell vehicles. However, Pike Research's study goes against the grain saying otherwise. According to the study, the U.S. will account for 134,049 annual FCV sales of the total 670,000, putting them in the lead for fuel cell vehicle sales. China will be in second place with 129,241 FCV sales and Germany will be in third place with 126,783 total annual sales.
Some believe these are "overly optimistic" results and that Pike Research is assuming that the appropriate refueling infrastructures will be available by 2020. According to fuel cell industry analyst Dave Hurst, "The entire growth of the fuel cell vehicle market balances on two key elements: the growth of hydrogen gas refueling stations and improvements in the cells themselves."
While improvements of fuel cells is in the works, the possible growth of hydrogen gas refueling stations is here. Currently, there is only one personal, zero-emission refueling station for FCV's that runs on sunshine and tap water. It's called a residential hydrogen refueler, and the only one that exists is hidden on the Torrance campus of Honda R&D.

Factory opens in Finland to supply lithium-ion batteries for up to 3,000 electric vehicles

The engineering and construction company M+W Group has successfully completed its first order to build a lithium-ion battery plant in Varkaus (Finland). The plant, which was commissioned by the Finnish battery manufacturer, European Batteries Oy, has now started full volume production.
The new factory in Varkaus has a surface area of 10,000 square metres and manufactures large, lithium-ion based battery packs and systems with an annual production capacity of around 100 megawatt/hours. This means that around 3,000 full-electric cars can be fitted with lithium-ion batteries, although a possible tripling of production is already planned.

Global leading Electric Vehicle to Appear in Shenzhen

The 25th World Electric Vehicle Symposium and Exposition (EVS-25), an international pageant for the development of new energy auto, will be held in Shenzhen in November.
Held once a year and a half, the World Electric Vehicle Symposium and Exposition, the largest and most powerful international summit and exposition in nowadays’ electric vehicle and new energy auto fields, is held in turn in Asia-pacific, American and European countries, which will unite the authoritative academic groups of the holding countries to submit applications to the World Electric Vehicle Association and can hold the exposition after approved.
The exposition will exhibit the latest technology fruits and its future development trend of each country with the whole vehicle, auto components and basic supporting facilities.

Man charged up about plug-in cars

In the parking garage near the South Carolina Aquarium, a man pulling out of his parking spot asked James Poch a question recently about his modified Toyota Prius
"You really get 100 miles to the gallon in that thing?"
James Poch, whose nonprofit organization Plug In Carolina wants up to 14 electric car-charging stations installed in downtown Charleston by December, gets that question all the time. His answer is "yes."

Electric cars provide future transportation needs

My magic wand is on the fritz, otherwise we'd have a big, new federal program to free America from its dependence on oil. Like other environmentalists, I'm sad that the calamity in the Gulf of Mexico hasn't spurred Washington to more vigorously promote America's exit from this curse.
The fault may lie with President Obama's timidity, a public scared by major new government programs or fossil-fuel interests flashing their campaign dough. Probably it's all three, but the bottom line is this: An all-out effort to unchain America from hydrocarbons is essential to national security, a healthy environment and economic prosperity in the 21st century. But it's not politically possible.
And so we must look at what's passable. Fortunately, there's one piece to the escape strategy that business leaders, military brass and the buying public all like — and would create jobs. Most importantly, it has bipartisan support in Congress.

With I.P.O., Tesla Bets on Electric Car’s Future


As Tesla Motors begins selling stock to the public on Tuesday, the offering’s success depends on how much investors are willing to bet on a car company that has never made a profit and expects to lose money until at least 2012.
Tesla will be the first automaker to go public since the Ford Motor Company held its initial public offering in 1956. It expects the stock sale to raise up to $185 million, The Associated Press reports.
The start-up company, which is based in Palo Alto, Calif., believes Americans’ taste in cars is changing. Most analysts agree that electric cars like Tesla’s will catch on as gas prices rise and environmental worries mount.
But Tesla faces bigger questions. It has lost $290.2 million since it was founded in 2003 and has not had a profitable quarter.
It does not expect that to change until it starts selling its next vehicle, a four-door electric sedan called the Model S, in large numbers. That is not scheduled “until 2012, or possibly later,” according to its filing with the Securities and Exchange Commission.

Valley has become hub for electric vehicles

With Tesla Motors leading the way, Silicon Valley has become a hub for electric vehicles. It is also home to some of the top companies working on the infrastructure to keep the cars running and on the road.
Former Brocade CEO Greg Reyes was sentenced to 18 months in prison for his role in a securities fraud case that emerged as the centerpiece of the stock-option backdating scandal that rocked Silicon Valley in the middle part of last decade.

London gears up for electric vehicles

25,000 charge points to be in place in capital by 2015
On the day that London has been branded as having the poorest air quality in Europe, Transport for London has unveiled its plan to ramp up the use of electric transport in the capital.

The plan appears geared towards electric cars - 1,000 of which are set to become part of TfLs fleet in the next few years – and the move will see the introduction of 1,600 charge points across London by next year and 25,000 within five years. At that point no Londoner will be further than a mile from a charge point.

Tesla IPO: Will build electric cars for $178 million

Tesla Motors, whose $109,000 electric Roadster is vividly familiar to anyone who’s ever picked up a car magazine (or, recently, a business one) is trying to go public and raise $178 million (up from $100 million). My guess: They’ll do it, because Tesla is a very sexy business, with a great image. Who wouldn’t want to tell people at cocktail parties that they’re an investor in Tesla?

The harder part will be getting the company out of the high-end luxury niche it is in now. Tesla’s strategy is clear enough: It’s rolling out the Model S at $49,900 (inclusive of a $7,500 federal tax credit) late next year as a 2012 model, and with the money that better-selling sedan brings in will then prepare an even-more-affordable third car. At that point, a publicly traded Tesla Motors will go mainstream and get out of the niche.

In a big shift, electric cars are just around the corner

IRVING -- Electric vehicles are coming to Texas soon, and along with them a vastly different experience in buying, owning and driving a new car.
With two automakers preparing to roll out the first mass-market, plug-in electric autos this year, the auto industry, retail electricity providers and government agencies are moving to make it easier for consumers to embrace the environmentally friendly technology.
Speakers at an electric-vehicle conference here said the looming introductions of the Chevrolet Volt and Nissan Leaf, which their manufacturers say will be delivered this year, are the vanguard of a movement that has enormous promise for Texas drivers living in pollution-plagued urban areas.
The basic technology to make electric vehicles practical "is already here today," and Texas is the perfect market for it, said Robert Nelms, director of the Institute for Intelligent Energy Systems at the University of Texas at Dallas.
Chevrolet says it will begin delivering the Volt, an electric car with a backup gasoline-powered generator, to buyers around December. Nissan plans to begin deliveries of its all-electric, 100-mile-range hatchback to the first U.S. buyers by year's end.
"We could see a significant [market] penetration of all-electric vehicles over the next decade," especially as the technology improves and consumers learn about it and become comfortable with the concepts, Nelms said.

Electric Vehicle Consumer Adoption Summit, Day One

Today was the first day, and as conference chair, I’ve had a hand in every session and been able to meet an interesting mix of thought leaders who really understand the electric vehicle space.
But even after devoting two full days to this event, the summit only breached the surface of what EVs are all about.
This is a great, deep dive for me – at our next summit we’re doing one session on EVs. And after what I saw this week, I can tell you there’s a whole lot more to explore. This article is a brief recap of the highlights, and I’ll do the same for day two in my next write-up.
The summit started strongly with a presentation from Marc Tarpenning, one of the co-founders of Tesla Motors. For those who don’t know Tesla, their Roadster really embodies the sex appeal of electric vehicles; it’s really sharp looking, has all the power you crave and of course, is very eco-friendly. However, there’s a six figure pricetag (News - Alert) with that, so it’s not going to recalibrate the balance of power any time soon, but it’s setting the bar high for what electric cars can strive for.
Marc gave us a lot to think about, and I could build this whole article around his comments. The key topics included why the time is right now for electric vehicles and why earlier entries like the EV-1 failed. Not being very technical, I really enjoyed Marc’s practical insights, especially as they concerned the global market opportunity for electric cars (including how important behavior change and attitude shifts will be to the success of this market.) I also enjoyed how he identified home-charging as a great opportunity for utilities to deploy smart grid/smart home solutions and make themselves a more active part of the electric car equation.

Battery Electric Vehicles vs. Hydrogen Vehicles

President George W. Bush promised that a child born at the beginning of his administration would be able to buy a hydrogen fuel cell vehicle as their first car. President Obama proposed that we deploy 1.5 million plug-in battery vehicles by 2015. Electric platform vehicles are going to be required to meet ambitious global climate change targets such as a 76% reduction from 2005 levels by 2050.
However, these vehicles will be more expensive than advanced gasoline vehicles. While lower fuel costs on a cents/mile basis can offset additional vehicle costs, 2015 may be too early to market either option commercially. However, the electric options can be more competitive as gasoline approaches $4+/gallon in the future1.
If the fuel cell system manufactured cost is about $50/kW and the hydrogen storage system is about $13 to 17/kWh, then fuel cell vehicles would be about $5000 to $7000 more expensive than a gasoline vehicle. The current DOE assessment for fuel cell system costs when mass produced in quantities of 500,000 is $60/kW2 and that 5000 psi and 10,000 psi hydrogen storage tanks meet the above values respectively3. Thus sufficient progress has been made on these component costs for automobile manufacturers to consider early marketplace entry by 2015. In fact Toyota, Honda, Daimler and GM have made public announcements that they plan to have tens of thousands of fuel cell vehicles available by 20154 and demonstrate 5000 hour fuel cell system durability to provide the public with a reliable product.

Tesla CEO to investors: We're like Google or Apple

Tesla's Motors' prospects for becoming a 21st-century auto powerhouse have as much to do with its Silicon Valley culture as with its technology, CEO Elon Musk told investors.
During a video recording prepared in advance of Tesla's initial public offering, which could come as early as next week, Musk touted the combination of the company's auto industry and Silicon Valley roots as a key competitive advantage.
"We're closer to an Apple or a Google than we are to a GM or a Ford," Musk said, adding that Tesla doesn't suffer from a slow, bureaucratic culture. "There will not be anybody that will bring technology to market faster than Tesla."
The forthcoming Model S electric sedans will be as high-tech as they come, equipped with a 17-inch touch-screen computer and a design inspired by slick consumer electronics, he said. "The best way to add value to a product is to make it really good-looking and appealing."
Telsa Motors plans to raise an estimated $178 million by going public, with a valuation of over $1.4 billion, according to reports. It's a sign of how electric transportation has shaken up the auto business and created an opportunity for young companies to crack into the auto industry with new technology.

Toshiba to expand Houston factory to produce electric vehicle motors

Electronics company Toshiba Corporation said it will expand its manufacturing plant in Houston, Texas, to produce drive motors for electrified vehicles.
The company said the project would mean setting up its first automotive propulsion systems production facility outside its native Japan.
Currently, it produces systems in Mie Prefecture on Japan’s Honsh? island.
The expansion in Houston comes after the company won a contract to supply propulsion systems for the Ford Motor Company.
From 2012, Toshiba will produce propulsion motors in Houston for hybrid electric vehicles, plug-in electric vehicles and electric vehicles, it said yesterday.

“Promising business”

“Toshiba recognizes the importance of localizing production within North America to ensure long term growth and make a commitment to the North American market,” said Shinichiro Akiba, President of Toshiba International Corporation.

Mercedes SLS AMG E-Cell Prototype Previewed

The world of electric vehicles has just appointed a new ambassador, as Mercedes has presented the prototype of the electric SLS AMG supercar, dubbed SLS AMG E-Cell. AMG’s aluminum spaceframe has remain unchanged, but now it includes completely different internal organs.
The vehicle is powered by four electric motors, two for each axle. The units are not mounted on the wheel hubs, but they are situated low and close to each wheel. The positioning of the front motors required that the double wishbone suspension of the gas-powered SLS was replaced with a multi-link setup that uses push-rod dampers.
The 12,000 rpm motors offer a combined output of 526 hp and a maximum torque of 649 lb-ft, allowing the vehicle to reach 60 mph in a sharp four seconds.

Electric vehicle charging points set for green light

Electric car charging points will be provided at Cambridge car parks later this year – and motorists probably won’t have to pay for the power.

Special bays will be reserved at two multi-storey car parks for electric or hybrid vehicles, with special plugs provided so drivers can top up their batteries.

It looks likely the charging period will be limited to three hours, but there will be no cost beyond the usual parking fee.

At first there will be two spaces at Queen Anne Terrace car park, and another pair at Grafton East.

Cllr Clare Blair, Cambridge City Council’s climate change chief, said: “We have a commitment to reducing carbon emissions in the city centre and encouraging people to use more sustainable transport, including electric cars.

“The proposal is to impose normal car parking charges and to give drivers the electricity free of charge, and that’s a very generous offer in these days of rising electricity prices.”

Electrics, hybrids grab Concept Vehicle Awards

Electric vehicles and hybrids swept the 2010 North American Concept Vehicle Awards. The Nissan Leaf, Audi E-tron and BMW Vision EfficientDynamics won the awards, which recognized the most significant concept vehicles automakers introduced at the top auto shows in North America.

The 2010 awards also mark the first time no U.S.-based automakers won any of the awards. Chrysler and General Motors cut back sharply on the number of concept vehicles they created as they went through bankruptcy reorganization last year.
The global economic meltdown led automakers all over the world to create fewer concepts in 2009, leading the jury to reduce the number of awards from five to three.

Work begins on $322m electric vehicle battery factory in Michigan

The first phase of the facility will see a 400,000 square foot production plant built, starting up in 2012
Construction work officially began yesterday for a new manufacturing facility in Michigan, which will produce batteries for electric vehicles.
Vice President Joe Biden and Michigan Governor Jennifer Granholm attended a ground breaking ceremony to celebrate the start of work at the advanced battery facility in Midland.
The facility is being build by Dow Kokam, a joint venture between the Dow Chemical Company and battery specialist TK Advanced Battery.
When complete, the 800,000 square foot facility is set to build 1.2 billion watt-hours of lithium-ion batteries each year – enough batteries for 60,000 fully electric of hybrid vehicles a year.
The facility is being built in two phases, with the first $322 million phase supported by a $161 million federal grant from the Recovery Act.
Some 320 jobs will be created by the first phase, set to begin operations by 2012, while the completed plant is expected to require nearly 800 workers from 2015.

Cash Back Rebates for New Electric Vehicles

The Ontario government has introduced a cash rebate program that will reward the first 10,000 applicants that buy or lease a new plug-in hybrid electric or battery electric vehicle after July 1, 2010.
Persons, businesses and organizations are eligible to apply for an electric vehicle cash rebate.
The cash back rebate amounts range from $5,000 to $8,500.
Critics argue that the cost of an electric vehicle can be prohibitive, so the cash rebates will likely have limited impact on increasing the sales of these fuel-efficient and environment-friendly automobiles.

Prices for Buying Electric Vehicles

The Nissan Leaf is an all-electric automobile with zero emissions. The Leaf is set to be introduced in the Canadian market late in 2011.
The estimated sticker price for the Leaf will be roughly $35,000 (in Canadian currency). According to a report from Metro Canada’s Ben Knight, the electric car currently sells in the United States for $32,700 (in American currency).

Travel Range for Electric Vehicles

Toyota Prius Plug-in Hybrid

This is a Prius like no other – a plug-in electric Hybrid which Toyota claims will do an astonishing 108.6mpg and emit just 59g/km of C02.  

The biggest difference between this car and the regular third-generation Prius is in it’s electric power source. The Plug-in version uses Lithium-ion batteries for the first time in a Toyota. They can carry more energy and recharge faster (a full charge now takes just 90 minutes) than the smaller nickel-metal hydride units fitted to the current Auris and Prius hybrids.   

Although they add an extra 130kg to the kerbweight, the new batteries increase the all-electric range from two miles to a much more useful 12.5, while the top-speed in EV mode is now 62mph. That means that during most town driving, the 1.8-litre petrol engine remains firmly off, only stirring into life if the throttle is pushed right to the floor.  

During our test the engine only cut in once, and the transition between the two power deliveries is completely seamless. The Prius is eerily quiet, but still performs reasonably well - the electric motor providing enough power and torque to easily keep up with traffic.

An Esoteric Presentation On Electric Bikes In India

This Article was shared by one of EVHUB's esteemed visitors Mr. G.Raghavan via email. 

"Just like food and water, personnel mobility is a necessity of human existence
Poor and developing nations like India depend largely on I/C engine for 2wheeler for the mobility of it's working n middle class .As a result of this India has emerged as the largest manufacturer of 2 W bikes/scooters in the world (even over taking china-incidentally 12 provinces of china has banned the use of I/c engine)
Basically I/C engine vehicle offers convenience, low cost; range also does not require grid power, the fall out of this
a)      Many players have emerged as manufacturers
b)      Created well established service net work
c)      Development of component suppliers
d)      Created skill jobs locally
The negatives:-
a)      Energy conversion in I/C engines is only 20% on calorific value
b)      Spews large quantities of carbon di oxide an environment threat
c)      Huge noise pollution
d)     Under dense city traffic wastage of fuel at signals due to idling
The futility of depending on "Fossil Fuels" has been an impetus to look for alternate solutions and energy.

On the solution side a paradigm shift towards usage of electric vehicle/ battery operated transport mechanism is on the horizon, this has brought about a lot of R&D work and demonstrable benefits (more of it later), on the energy side Renewable energy like wind, solar etc are making inroads into the established methods of power generation with evident benefits of green energy.
Hence the alternate to personnel transport could be an electrically powered vehicle
The main constraints associated with E-Bike/Scooters are
  1. Cost along with battery
  2. Range
  3. Inconvenience
  4. After sale service
  5. Power requirements

Dwelling on each of the above issues

How About Creating An Electric Vehicle Platform For Individuals Businesses And Like Minded People

The below email was sent by Mr. M.N.Ananth, MM Technologies., Sm-160, 3rd Main, Hebbal Industrial Estate, Mysore-570 016

A proposal to create an electric vehicle platform with like minded people who are into this field. Members can be individuals, companies, researchers or any EV enthusiasts. Please go through the below message and do comment on requirement of a "Common platform for electric vehicles" and why ? 

Join EVHUB Forums to start your discussions and share your views on it. 

Attention Mr.Murali/EVHUB

There are lot of individuals, industries, experts and technocrats in our country well versed with sound knowledge of electric vehicles and its components and spares.

It is a fact that major industries in any part of the universe are dependant on small scale industries, it is very clear that the big industries or the major industries they depend on the expertise and infrastructure of the small scale industries for supplies or the technology and components.

You must have seen in some of the exhibitions Mr.Ahmad of Bangalore displaying his own technological invention of 3wheeler auto-rickshaw., and he has also been honoured by several state governments, but what has happened to him., he is unable to make his dream come true, the simple reason that, there are no industries or individual to support him financially.  Even in my case everything is ready.,  you are aware that we have indigenized the electrical cycle to the maximum, even though we have a very good market feed back, we are lagging behind because of the financial reasons.  There are manufacturers of BLDC motors in our country, and they are unable to leap further. One or the other reasons many of us are forced to under go through the bad patch of the finance matter.

Hence I suggest that, as already you have made a platform as EVHUB, I suggest that you can invite the like minded individuals or the companies or the groups and involve everyone in the discussions.

Brushless DC Motors - Technology For Future Transportation

Now a days world is plagued with global issues like fuel shortage, global warming. No doubt Electric Vehicles are the solution for fighting against these issues. As convectional vehicles has fuel as energy source and engine as prime mover, Electric vehicles uses battery as energy source and electric motor as the prime mover to drive. The various options available for driving electric vehicle are DC motor, induction motor, and Brushless DC motors. 

In Electric Vehicle, there should a portable power supply. Hence we can use Battery to power the vehicles and DC is the default power supply. 

DC Motors: These motors constitutes of Brushes and commutator which will act as a mechanical position sensor on rotor and supplies the power supply to corresponding stator winding so that there will be a forward torque produced in the motor. Advantage of this motor is its constant torque characteristics at various rotor positions. But  following are the disadvantages of this motor  
  • The Brushes will be wear out due to constant contact between rotation and stationary portions of motor.
  • The commutator segments might get shorted due to the burned carbon precipitated in between which might result in unbalancing of the motor operation.
  • Low operating efficiency


Hence, a DC motor needs a periodic maintenance to prevent it from permanent damage.

More electric vehicles will change electricity markets

19 de junio de 2010

Ford Motor Co. has announced it expects up to one-fourth of its fleet to be electric vehicles by 2020, only a decade from now.
More electric vehicles will change electricity markets
Stories in USA Today and the Detroit Free Press note that of those electrified vehicles, 70% will be hybrids, 20% to 25% plug-in hybrids, the rest pure electric cars. 

Ontario to offer rebates on electric, hybrid cars

The Canadian Press
TORONTO — The Ontario government will offer consumers a rebate of between $5,000 and $8,500 if they buy a new plug-in hybrid or fully electric vehicle after July 1.
But the rebates will only be offered to the first 10,000 applicants who qualify, the government said Friday.
Details of eligibility for the rebate were not immediately available, but the government said it would provide full criteria and application forms on the Ministry of Transportation's website beginning July 1.

Federal grants fund thousands more electric vehicle charging stations

With six months before the release of major new electric car models from the likes of Nissan, Chevrolet and Ford, thousands of new public and home-based recharging systems are being installed.
The new infrastructure is initially focused on certain urban areas seen as key markets for new electric vehicles.
ECOtality, which began developing its plan for 12,000 new charging stations under its EV Project in October, said this week it is extending the program to Los Angeles and Washington DC thanks to an extended federal grant.
It will also extend its offer of free charging systems to include new owners of the Chevrolet Volt, and 1,000 more Nissan LEAF customers.
Another recharging company, Coulomb Technologies, which started installing 4,600 charging stations under its $37 million ChargePoint America program this month (see this BrighterEnergy.org story), will now also be providing 1,800 home charging points to Chevy Volt customers.
Chevrolet – one of General Motors’ brands – is the only motor manufacturer to be funding recharging infrastructure under both the EV Project and ChargePoint America schemes.

Electric Vehicles- The Clever Ten Year Strategies

The electric vehicle business is over $33 billion today at ex factory prices but cars are less than half of that. As the market nearly quintuples over the next ten years, cars will rise to nearly 55% of the business but the devil is in the detail. Last year, Mitsubishi expected to make its electric car business profitable by 2013 but then Nissan warned that governments may cut back subsidies for electric cars due to the ongoing global financial meltdown and profits may slip far into the future. Certainly, most of the profits in electric vehicles will remain beyond mainstream electric cars for the next ten years. In 2020, the car manufacturers will still be slogging it out to see which three end up with secure, profitable growing electric car businesses of tens of billions of dollars in the decade after that, when growth eases.
Many profitable electric vehicle manufacturers
By contrast, today there are already many profitable electric vehicle manufacturers with other strategies, including Linde in electric forklifts, Kongsberg in Autonomous Underwater Vehicles AUVs, Jinangsu Xinri Electric Vehicle Company in e-bikes, Pride Mobility in electric mobility vehicles for the disabled and Tesla in designer sports cars. Little wonder that more and more of them are expanding into several other, carefully chosen multi billion dollar EV sectors.
Profitable traction batteries
Much the same picture pertains with traction batteries, the largest single driver of cost and performance of most of these vehicles. Here there is even more horizontal selling but the savvy players choose their targets carefully. For example, Electrovaya of Canada recently showed its first profit of $549,000. A manufacturer of battery operated healthcare products, its entry into traction batteries has been in specialist vehicles such as the Hummer military vehicle, the Dodge Ram pickup truck and the Canadian Maya low speed car, Tata and Hero. Its batteries are the safer lithium polymer type.
 
The new IDTechEx report "Vehicle Traction Batteries 2010-2020" looks at all traction batteries and the winning strategies. The rapidly growing market for traction batteries will exceed $55 billion in only ten years. However, that spans battery sets up to $500,000 each with great sophistication needed for military, marine and solar aircraft use. Huge numbers of low cost batteries are being used for e-bikes but even here several new technologies are appearing. The largest traction battery replacement market is for e-bikes today and the value market for replacement batteries will not be dominated by cars when their batteries last the life of the car - something likely to happen within ten years. The trends are therefore complex and that is why IDTechEx has analysed them with great care.
 

Time to Plug In Electric Cars

It's fair to say that President Barack Obama's speech to the nation on the oil spill this week didn't exactly get rave reviews. It was variously described as flat and vague—and that was by his friends.
And maybe there was just nothing he could say at this moment of helplessness in the face of the gushing oil that could have made it otherwise.

Mitsubishi to cut price of electric cars

Company says aims to cut prices but gives no time frame
* Mitsubishi Motors shares outperform broader auto sector (Adds company comment, share prices)
(Reuters) - Mitsubishi Motors Corp (7211.T) aims to cut the price of its electric vehicles to 2 million yen ($21,890) by fiscal 2012 -- down 30 percent -- to capitalise on the growing popularity of hybrids in that price range, the Nikkei business daily reported.
Mass production of lithium ion batteries, the most expensive component in an electric vehicle, will lower costs sharply, the Nikkei said.

Tata Motors charts green drive for JLR

Mumbai, June 17
Tata Motors is charting a strategy for a 25 per cent carbon dioxide reduction in its Jaguar and Land Rover models.
The company has taken into account volatile fuel pricing, continuing legislation on emission and taxing while focusing on its green initiatives.
In a recent presentation to analysts, Tata Motors said to build JLR's competitiveness it is aiming for a “strong technology strategy for a low carbon world by 2014”. This involves developing technologies targeting a 25 per cent reduction in the joint fleet average tailpipe CO2 emissions. The company banks on two ongoing research projects — Limo Green and Range-e.
Jaguar has already displayed the Limo Green concept, a hybrid XJ equipped with a 145 kW, 295 full-load motor torque electric motor, and a 1.2-litre petrol engine. This gasoline-electric hybrid claims a fuel economy of 57 miles per gallon (10 km/litre) and less than 120 g/km CO2 emission at its top speed of 112 miles per hour.
Range-e uses a plug-in parallel diesel hybrid system to offer a premium SUV that can run as a pure electric vehicle minimising emissions.

Electric Mini car trial 'is a success'

Peter McManners said he had learned to live with the car's limitations

A Berkshire motorist interested in green issues has said his trial of a new electric car was "a success".
Peter McManners, from Pangbourne, has been driving the Oxford-built Mini E car to test the electric car's suitability to everyday motoring.
He was one of 20 drivers in the trial, run by a consortium led by the car's manufacturer BMW.
Mr McManners said: "I've enjoyed having it but we've had to fit around its limitations, like its lack of range."
The left-hand drive, two-seater prototype is like a conventional Mini car, but its rear seats have been removed to make room for lithium-ion batteries.
Product development

Bellevue gets ready for electric cars

Electric cars are coming, and Bellevue aims to be ready.
Earlier this week, the Bellevue City Council discussed ways the city can be prepared when the first wave of highway-ready plug-in vehicles hits the state late this year.
The greater Seattle area is one of seven regions that's been chosen to participate in the rollout of the Nissan Leaf, a fully electric car that will arrive in December. About 1,500 Washington residents have pre-ordered the car, expected to run about $25,000 after substantial federal discounts. A prototype of the Nissan Leaf was on display in Bellevue last year.
As part of the rollout, a federally-funded project called The EV Project will deliver nearly 15,000 residential and commercial chargers to 13 cities in five states and the District of Columbia.

Lear ready for electric vehicles

Southfield -- Lear Corp. is embracing electric vehicles, and expects that making parts for this growing market will be lucrative -- quickly.
The Southfield-based supplier expects sales of components and systems for hybrids and electric vehicles to grow to approximately 7 percent of its electric systems business by 2012 -- from zero percent in 2009, said Raymond Scott, president of Lear's Global Electrical and Electronic Systems.
The sales target is $250 million in this new area. Lear's total global sales last year were about $2.3 billion.

Lear anticipated the growth of electric vehicles, so it invested in a new power lab at its Global Center for Excellence in Southfield in September 2008. But Scott said Tuesday he's shocked by the speed at which the technology is being embraced.
"I've never seen anything like this," he said.
