Chevy Volt Batteries and Vehicle Testing Hitting Milestones


Recent calibration drives of pre-production Chevrolet Volt electric vehicles have achieved up to 39.9 miles of emission-free, electric-only driving range, chief engineer Andrew Farah said Monday during a program update for news media.

The Volt, which can travel up to 300 miles beyond its pure electric range because of a small on board gasoline engine, recently completed a round of cold weather testing in Kapuskasing, Ontario, Canada, and will undergo additional hot weather testing in Yuma, AZ, in June and July.

The Volt remains on schedule for start of regular production in the fourth quarter. Farah, chief engineer for the Volt and the Opel Ampera, said more than 500,000 test miles have already been put on the pre-production Volt vehicles.

Farah said engineers at GM’s Warren, Mich., Technical Center will begin building pre-production versions of the Ampera later this month in preparation for its launch in Europe for the 2012 model year.

Monday’s update followed the announcement that GM plans to invest an additional $8 million to double the size of its automotive battery lab in Warren.

Micky Bly, GM’s executive director of global electrical systems, hybrids, electric vehicles & batteries said more than 300 pre-production packs were slated to be built at GM’s Brownstown, Mich., battery plant.

So far, more than 850,000 miles of customer use lab testing have been completed on the battery pack design for the Volt and Ampera. Bly said the team continues to study additional applications of the Voltec battery-based propulsion system in future vehicles, although no details were provided.

Electric Mini laps the Nurburgring


The Mini E has become the first all electric vehicle to complete a full lap of Germany’s famous Nurburgring at racing speed.

The specially prepared Mini completed a lap of the 20.8km circuit, considered to be the toughest circuit in the world, in 9:51.45 seconds - around one minute slower than a petrol powered Cooper S. Former German touring car driver and 2006 German Mini Challenge champion, Thomas Jäger, was the man chosen to take the wheel.

“I’ve driven this circuit many times, but never in such an extraordinary car,” Jäger said. “The power of the electric motor has an incredible effect, as you can access its full reserves of torque at all times. Another element of this fascinating experience is the lack of noise from the drivetrain. All in all, that was certainly the cleanest and quietest race lap I’ve ever driven.”

Mini already has more than 600 examples of the Mini E around the world undergoing testing. But the Mini E Race, as the car was dubbed, was given a major overhaul to tackle the Nurburgring.

Although the track car was powered by the same 150kW electric motor a special lightweight body was fitted to help improve performance. Other performance additions included new suspension, brakes and tyres. For safety the Mini engineers also installed a rollcage.

“The length and profile of the Nordschleife [northern loop of the Nurburgring] place extreme demands on the technology of our electric car,’’ said project leader, Peter Krams. ‘‘But the MINI E Race met this considerable challenge with great authority. The aim of this unique undertaking was to provide an impressive showcase of the great potential of the MINI E and its environment-friendly drive concept.”

But while the Mini E was the first fully electric vehicle to tackle the Nurburgring, Porsche is already well advanced with its hybrid-powered 911 GT3 R race car, recently completing two races at the track. Designed to compete in the Nurburgring 24 Hour race in June the 911 GT3 R Hybrid uses two electric motors powered by a flywheel generator, which captures energy normally lost in heat through the brakes. Unlike a battery, which stores electricity, the flywheel generator stores mechanical energy, later converting it to electricity for use in the motors.

Porsche has entered the 911 GT3 R in the Nurburgring warm-up races and scored a podium finish in last weekend event. The car, driven by Germans Joerg Bergmeister and Wolf Henzler, finished third in the four-hour race.

Nissan plan to sell used batteries on to wind farm developers


Electric car manufacturers are planning to give a second life to old batteries by selling them on to wind farm developers for use as a potentially cost-effective form of energy storage.

According to Sunday Times reports, Nissan is investigating pooling large numbers of old electric car batteries for use by renewable energy developers, who could use the technology to help cope with unreliable energy supplies.

Last October the company launched the 4R initiative with Sumitomo Corporation, detailing how it plans to "Reuse, Resell, Refabricate and Recycle" old batteries and is currently exploring how batteries could find a new life in the renewable sector.

The performance of electric car batteries deteriorates over time, but Nissan expects that lithium-ion cells it plans to use will retain up to 80 per cent of their residual capacity even after they are no longer useful for electric vehicles.

A company spokes person confirmed that the company was looking closely at the idea and was considering a business model for its soon-to-be-launched Nissan Leaf electric car that would see the firm lease out its electric batteries to motorists – ensuring that it retains ownership of the batteries.

KERS key to F1's green image


Williams team boss Sir Frank Williams believes reintroducing KERS to Formula 1 is essential for the sport's environmental image, and that the return of the energy-regenerating device would protect F1 from criticism from environmental groups and the press.

KERS remains in the regulations following its single season of use last year, but the teams agreed not to run it in 2010 on cost grounds. Its return was debated during meetings at last weekend's Malaysian Grand Prix, and Williams said he was strongly in favour.

"I've always believed that Formula 1 needs a totem, to avoid - which we have done so far - the attention of unco-operative members of the press who don't follow Formula 1 very actively," he said.

"I use the word totem, but to explain what I mean in very general terms - it's quite the wrong word because KERS is a very meaningful thing for emission control and it does save power.

"It's expensive, it's difficult technically and it's a big swallow, but sooner or later Formula 1's going to get some aggro from one of these bodies that causes aggro."

Last year only McLaren and Ferrari used KERS for the majority of the season, with BMW and Renault abandoning their systems and the other teams opting to run without the device - although most had evaluated KERS in testing.

Brawn and Red Bull fought for the championship without needing KERS, but Williams believes the technology has already improved enough that if it returned any teams not running the system would be uncompetitive.

"If three teams had KERS and the other seven didn't, the chances of winning races if you haven't got KERS - now that the systems are becoming better and better - [not having it] is a major handicap," he said. "I believe it should be compulsory or not at all."

Williams was the only team to try out a flywheel-based KERS alongside the battery versions favoured by the rest of the teams, but Williams added that the refuelling ban now made flywheel KERS impractical.

"We can't use our own KERS because that's a flywheel, which takes up more room, and the only place to put it is behind the driver," he explained.

"If the fuel tank is three times the size it was two years ago, and you want to put KERS in it, you'll have your car longer than a London bus... So we'll use it elsewhere."

In unrelated F1 news with McLaren threatening to introduce an active suspension system to adjust ride height between qualifying and the race, the FIA has stepped in to clarify that any such device is outside the rules. The Red Bull team, who have been accused by other teams of running such a device, insist that not only do Red Bull not have such a device, but that it will protest any team that runs one.

We here at EVN wonder how long it will take the rest of the F1 grid to realize that it now seems obvious the Red Bull team are most likely running a coil binding system on the front of their cars, similar in principle to those used in NASCAR.

This would explain the comments made by Mark Webber following his crash into Lewis Hamilton at the Australian Grand Prix where he claimed the crash was caused by a loss of downforce in the wake of the McLaren resulting in the front of his RB6 lifting up.

Carbon-fiber MacPherson strut concept by ZF



German auto parts supplier ZF has developed a concept Carbon-fiber MacPherson strut. The concept pictured above is designed specifically for European microcars, the smallest and cheapest cars out there. The lightweight strut is one of the cooler uses of carbon fiber and foretells the democratization of carbon fiber that we expect in the next ten years.

The MacPherson assembly boasts an integrated wheel carrier and piston rod made from carbon fiber, along with a fiberglass spring and plastic top mounting plate. Beneath the carbon fiber structural elements, there is still a damper tube made from steel to provide a durable wear surface. Total weight savings amount to 6.5 to 9 pounds at each corner, according to ZF.

The concept can easily be adapted to larger vehicles, but the original design is only able to accommodate cars that weigh less than 1000 kg. How will automakers afford to use one of the most expensive materials on the cheapest cars? ZF says fewer parts and reduced assembly complexity mean a carbon-fiber strut could have a comparable cost to the traditional suspension assembly. If they’re right, we could see this technology showing up by 2014.

Germany Firm Debuts Single Seater Electric Airplane



Calin Gologan, CEO of PC Aero introduced his Elektra One all-electric, single-seat airplane at Aero 2010 in Friedrichshafen, Germany. The 120 kg (264 lbs) composite airplane is powered by a 16 kW (peak) electric motor and has a operational endurance of up to 3 hours at 120 km/h. Its wingspan is 8.6 meters (28 ft) and it has an effective payload of 90 kg. (164 lbs).

It is designed to compete in the CAFE Green Flight Challenge in California this July. Partnering with NASA, the Challenge requires the aircraft to fly at least 100 miles per passenger on less than half a gallon of fuel or 17kWh of electric power at a minimum speed of 100 mph. The maximum range of the Elektra One is 400 km at 160 km/h.

PC Aero estimates that the all-electric airplane can fly up to 300 hours a year on the solar energy provided by just 20 square meters (215 sq ft) of solar panels, with an ROI of just eight years at current operating cost in Europe. It estimates flying clubs can operate Elektra One for €30 an hour.

EV Adaption Could Cure Many Economic Woes Says New Report


The Electrification Coalition today released a long-term macroeconomic analysis of the policy proposals put forward in its November 2009 Electrification Roadmap. The paper finds that the U.S. economy would benefit substantially over the long term from implementation of the Electrification Coalitionpolicy package.

"In short, the economic modeling shows that the electrification policy proposed by the Coalition offers significant and widespread benefits to the American people, including reducing our federal budget and trade deficit," Electrification Coalition member David Crane, President and CEO of NRG Energy, said in a speech given at the National Press Club. "I believe we are on the cusp of the next great tectonic shift in our economy, one that will transform the way we use energy both in our homes and on the road."

The Electrification Coalition, a group of business leaders representing the entire value chain of an electrified transportation sector, released their Electrification Roadmap in November 2009. The plan called for the creation of localized concentrations of electrification, geographic areas in which all of the elements of an electrified transportation system are deployed, thus providing a crucial first step toward moving electrification beyond a niche product into a dominant, compelling, and ubiquitous concept.

Shortly after releasing the Roadmap, the Coalition commissioned the Interindustry Forecasting Project at the University of Maryland and Keybridge Research to study the long-term economic effects of their policy proposals. A summary of the study's findings is attached.
Summary of Findings

The study being released today finds that the Electrification Coalition policy package results in significant economic benefits for the United States over the simulation period:

By 2030, total employment would increase by 1.9 million jobs. Among the interesting industry effects: by 2030 there would be 560,000 more manufacturing jobs, 276,000 more jobs in travel and tourism, and 73,000 more jobs in professional services. Employment in the motor vehicle industry (including motor vehicle parts) would be about 106,000 jobs higher than the base. Employment in the industries that supply key electric and electronic components to electric vehicles would increase by 112,000 jobs.

Over time, the federal budget deficit would improve as a result of the policies in the Roadmap. Because of the higher levels of income and GDP resulting from the policies, the U.S. federal budget deficit would improve by a cumulative (2010 to 2030) $336 billion, net of policy costs.
By 2030, the typical U.S. household's annual income would rise by $2,763 (2008 dollars). This represents an increase of about 2.2 percent.

Cumulatively, during the 2010-2030 period, households would experience an increase of $4.6 trillion (2008 dollars) in aggregate income—money that can be saved or spent on other goods and services.

By 2030, the typical U.S. household would spend less per year directly on energy for transportation. The combination of higher income and less spending on energy means that the typical household would be able to enjoy about $3,687 (2008 dollars) more in consumption of goods and services (or personal savings).

U.S. crude oil and petroleum product imports would fall sharply, by 3.2 million barrels per day by 2030. Cumulatively, between 2010 and 2030, the United States would import nearly 11.9 billion fewer barrels of foreign oil. This compares to estimated reserves of 4.3 billion barrels for Prudhoe Bay, and slightly less than 30 billion barrels for total U.S. proved reserves.

By 2030, the U.S. trade balance would improve by about $127 billion dollars (2008 dollars).
World demand for oil would fall, leading to lower world oil prices. Outside commodity price experts have estimated that the price of oil would be almost 7 percent lower by 2030 than it would be without the EC policy package.

The U.S. economy will be stronger and more resilient. The Electrification Coalition policies—once fully implemented—would mitigate roughly one-third of the economic losses caused by a future oil price shock. By 2025, the EC policies would prevent the loss of 1.4 million jobs in the first year alone of a price shock-induced recession.
