Tesla, other electric vehicles poised to enter the mainstream
April 11, 2011 By Dana Hull
After decades of sputtering starts and stalled hopes, the electric vehicle is poised to enter the mainstream.
Tesla Roadsters, Nissan Leafs and Chevy Volts are already on the market, and every major automaker has at least one electric model in the pipeline, giving consumers an array of choices in the coming years. The new wave of EVs just beginning to hit American highways is not the first - they were popular a century ago until cheaper, gasoline-powered cars gained dominance after World War I. But experts say the stars now appear to be aligned for an alternative to the internal combustion engine.
"This time it feels real," said Roland Hwang, director of the Natural Resources Defense Council's transportation programs. "Automakers are serious. There's oil price shocks. The long-term trends are very positive. There will be potholes in the road as this rolls out, but there aren't any showstoppers."
Advocates argue that EVs are not simply another type of car but a game-changer for the country. They say that widespread adoption of electric vehicles will help cut the greenhouse gas emissions that contribute to global warming and enhance national security by reducing the country's dependence on foreign oil.
The transition to EVs won't happen overnight, however. Current models have a limited range and are more expensive than most comparable gas-powered cars, making them unappealing to many drivers. But EV prices are expected to decline as high-volume production pushes manufacturing costs down. And Silicon Valley startups are racing to improve battery technology, which should allow the cars to go farther between charges. When that happens, manufacturers and enthusiasts hope electric cars will become a viable option for millions of Americans.
OVERCOMING CHALLENGES
Tech-savvy early adopters such as Felix Kramer and Rochelle Lefkowitz, of Redwood City, Calif., are already sold. The couple outfitted their Toyota Prius, which operates on electricity as well as gas, with a larger battery pack in 2006. In December, they bought one of the nation's first Chevy Volts, which runs on electricity for about 40 miles before its gas engine kicks in. In January, they added an all-electric Nissan Leaf to their household fleet - making them the only family in the nation known to own three plug-in vehicles.
"I drove the Volt to get a haircut the other day, and people on the road were waving at me and giving me the thumbs-up," said Lefkowitz, who has grown used to strangers stopping her to talk about cars.
For EVs to enter the mainstream, the auto industry has to reach beyond enthusiasts like Kramer and Lefkowitz and appeal to a mass audience. The potential market is huge: Last year, Americans bought 11.6 million new cars and light trucks, and some analysts project sales of 16.3 million in 2015. If EVs can capture even a modest slice of that market, experts say, they could reduce America's dependence on foreign oil.
Sales of EVs are expected to be modest for the next few years because of their limited range, relatively high cost and a shortage of charging stations. There are currently about 120 public electric vehicle chargers in the San Francisco Bay Area, with more than 2,000 more planned in the next five years under a state program.
But despite such challenges, many in the industry point to encouraging signs.
'DEMAND IS OUT THERE'
When General Motors first launched the Volt, plans called for 10,000 to be built by the end of 2011 and 45,000 by the end of 2012. But GM is accelerating production, in part because some companies are turning to the vehicles to power their corporate fleets. General Electric has already ordered 12,000 Volts.
"It appears we've underestimated," said Tony Posawatz, the GM executive in charge of the Volt, adding that GM plans to make at least 15,000 Volts this year. "It's still early in the launch, but we're getting more and more feedback that the demand is out there. It's very much like using a smartphone - once people have the experience of driving electrically, they don't want to go back."
The Obama administration wants to see 1 million EVs on the road by 2015 and has proposed replacing the existing $7,500 tax credit with a $7,500 rebate at the time of sale to spur demand. Some analysts worry that goal will be hard to reach, even with robust government incentives. Mike Omotoso of JD Power and Associates thinks no more than 700,000 to 750,000 plug-in and pure EVs could be on American roads by 2015.
"The cost of the vehicles is too high, and gasoline-engine powered cars are getting more fuel-efficient all the time," he said. "Almost all new compact cars are getting 40 miles per gallon on the highway now, so why pay twice the money for an electric car that only has a 100-mile range?"
But rising oil prices could change that calculation.
"In early 2008, when gas went above $4 a gallon, all hell broke loose," said Alan Baum, a Michigan-based auto industry analyst. "Larger cars went out of fashion, and people started buying smaller cars and hybrids. If the price of gas goes up and stays up, that will increase consumer interest in EVs, plug-ins and hybrids."
EDUCATING CONSUMERS
Still, the EV industry faces significant obstacles, not the least of which are the current limits of battery technology. The most expensive part of an electric car is its lithium-ion battery - both because of the cells themselves and the sophisticated control systems needed to regulate temperatures around them.
"Batteries are heavy and bulky, and right now to extend range you just add more batteries," said Sunil M. Chhaya, an electric drive expert at EPRI, the Electric Power Research Institute, in Palo Alto. "They take up a lot of space inside the car, and everyone wants to reduce the size."
Doing that will require improvements in "energy density," which refers to the acceleration and range the batteries can provide. Toward that end, the Obama administration has given $2.4 billion in federal stimulus dollars to 48 advanced battery and electric-drive projects. Battery startups such as Envia Systems in Hayward and Amprius in Mountain View are attracting venture capital, and companies such as Coulomb Technologies of Campbell, which makes networked charging stations, are growing rapidly.
Another hurdle for electric cars is lack of public awareness. Many Americans still know very little about them, or have concerns about cost, range, safety and charging requirements.
In a recent survey of 1,716 American drivers conducted by IBM, about 40 percent said they had heard only "a little bit" about electric cars. One in five said they would be likely or very likely to consider an EV for their next auto purchase. But half of all respondents said they would not be willing to pay more for an electric car than a gas-powered one, and nearly a third said they would not be willing to invest in a home charging station.
"We saw a big education gap," said Kal Gyimesi, head of automotive research for IBM. "The more knowledge people had about EVs, the more viable an option it became. The EV industry has to continue to educate consumers about why this is a viable product."
And at the moment, there's one other obstacle: you can't just go to a dealership and buy an electric car straight off the showroom floor. In most cases, consumers must order the car months in advance of delivery.
CALIFORNIA TO DRIVE SALES
The first big push for electric vehicles came more than a century ago. In the 1890s, electric taxis were common on the streets of New York City. When President William McKinley was shot in 1901, he was driven to the hospital in Buffalo, N.Y., in an electric ambulance. Henry Ford purchased an electric vehicle for his wife, Clara, and also worked with Thomas Edison on an electric vehicle model. Sales of plug-in vehicles peaked in 1912, when 6,000 were sold.
In the late 1990s, GM briefly produced the EV1, but consumers could not buy the car outright - they had to lease it. GM canceled the EV1 in 2003, inspiring the 2006 documentary film "Who Killed the Electric Car?" (Filmmaker Chris Paine's sequel, called "Revenge of the Electric Car," is having its world premiere in New York on April 22 - Earth Day.)
In addition to the Roadster, Leaf and Volt, a wave of EVs is expected to launch in California later this year, including the Coda Sedan, Ford Focus Electric and Mitsubishi "i." Tesla's Model S - one version promises a range of 300 miles - and Honda's Fit EV are scheduled to hit the market in 2012. Audi, Daimler and Volkswagen are also developing electric vehicles - there's even buzz about a possible all-electric Volkswagen bus.
Pacific Gas & Electric has analyzed hybrid vehicle registration data and says the Bay Area will be "ground zero" for EVs, particularly in the Peninsula, East Bay and Marin County. It expects anywhere from 219,000 to 845,000 electric vehicles to be on the roads within its vast Northern California territory by 2020.
Kramer and Lefkowitz, with their three plug-in cars, are among those leading the charge. Kramer is the founder of CalCars, a small nonprofit organization that promotes plug-in hybrid electric vehicles (PHEVs) as the key to reducing America's dependence on foreign oil.
"We have to stop using fossil fuels as quickly as possible," Kramer said. "If more people understood the urgency - both of saving the planet and in terms of energy security - we could get there even faster."

if we passed a law banning the export of oil by the oil companies, so they can't sell OUR oil to someone else, then lift all the drilling bans and allow companies to drill at wiil, then the U.S. would have enough oil to last at present consumption levels for well over 100 years, which is plenty time to develop more battery technologies, or Rossi's LENR device, or solar, etc.

You want "mainstream"? There's your basic spec.
A 50-mile range puts it squarely in the commuter class, plus shopping. People could then park their oil burner unless they planned a longer trip, which would eliminate over 90 percent of the old car's usage. The $12 grand price point puts it in range of America's swelling lower class workers. GM's own skateboard chassis would allow mass manufacture using inexpensive materials, with a steel-reinforced plastic shell on top. Drive-by-wire controls eliminates mechanical linkages from controls to servos and motors. Lead acid batteries would probably suffice for power storage, with the addition of desulfators to prevent sulfate buildup. Nothing new, no ground-breaking innovations.
So, where are they?

So you're proposing that other countries be stopped from selling their oil here? because that's what would happen if we banned exports. Also say goodbye to any American company currently involved in drilling oil overseas. I suggest that you look up the word fungible. And no we don't have 1.3 trillion in reserves. There are no drilling bans and currently oil companies are sitting on several million acres of unused land in which they already have the right to drill. Get real facts before you to spouting off.

That would be great. Then the environmental impacts of oil drilling would become obvious to us and the incentive to get off oil would be more evident.
As for this article -- it neglects to mention that the fact that the battery charging takes hours also makes it impractical for many of usto buy electrics until that issue is solved. "Consumer education" is not the problem. Consumers know what they want to buy, generally. YOu have to solve the problems and make it really work before I'm going to buy it.

Specifically, it came from a FOX news contributor who is primarily involved in oil production, and HE said that there is around 300 billion barrels off shore of California, around another 300 billion for Florida, and then around 700 billion in shale oil.
That comes to a total of 1.3 Trillion barrels.
Additionally, the reason I used the "at current levels" projection is because American has a net negative "legal" population growth rate. We would have a "true" net negative population growth if not for illegal immigration.
At any rate, our population is only growing around 3% per decade, and almost all of that is due to illegal immigration and increased life expectancy(thus aging population).
Also, the raw numbers actually suggest 178 years at present levels, so there was plenty of "padding" for some population increase.

It also neglects to mention that electricity is more expensive per unit energy than gasoline (even though it's true that due to increased efficiency, the per miles cost would be lower for electric).
However, you are correct. Presently, charging takes too long, and there are no "off grid" options for the majority of people, since your vehicle isn't home during the day to be charged by a personal solar power supply.
One gallon of gasoline equivalent worth of electricity is 36.39 kilowatt-hours. So even though electric is like 80% efficient, in order to get 70 to 80 miles worth of charge requires around $4.00 to $5.46 worth of electricity (cheaper than gasoline,) BUT in most cases it's 8 to 12 hours or more of charging.
Ironically, covering the car in solar panels ends up being one of the cheapest re-charge options.

That's using existing coal and nuclear powered grid technology.
As oil is forceably phased out by the U.N. and American liberals, the price of electricity will go up (demand) if/when people do switch to electric cars.
To do that same charge for the Leaf using say, solar PV cells on your roof would take 7 or more hours for an array of 24 panels of 1.5 square meters each...not counting losses due to heat waste* and transmission in the battery charging.
* Solar panels lose about 10% of their specified watts due to heat waste making them less efficient. So for example, if a panel is rated at 220 watts, then on a hot clear summer day it will only actually produce around 198 watts, because as it gets heated up due to heat waste it's efficiency falls. If you submerge a PV panel in water it's power actually goes up, because the water helps carry away the heat waste, which increases efficiency.
So anyway, it takes over 24 typical solar panels to do that charge in 7 hours...

The problem is, again, it doesn't work, because most people work during the day, so they aren't home to charge their car on Solar power.
the only real alternatives to that is to have swappable batteries (highly unlikely since they are so heavy,) OR to have extra batteries at home which charge during the day, and then use those to charger your car at night, but you lose about 30% efficiency this way.

The EV1 was based on completely outdated technology of lead-acid batteries which require periodic "top-ups" and maintenance. In an era of cheap col-fired electricity also it didn't make economic sense.
Apart from a few "pioneers"/eco kooks no one really cared about it. The current generation based on Li-ion batteries are more realistic.
Face it - The EV1 failed only because it was based on outdated technology. I'd rather corporations control things more than the government which does a very poor job at it.

70-80 miles of driving in a Nissan Leaf for example cannot consume that much electricity because it doesn't have 36 kWh in the battery. It has 24 kWh, yet it can go up to 130 miles with it and 75 miles isn't out of the ordinary.
With the average prices, you'd pay about $2.64 for a full charge, and the charging time is practically limited by your circuit breaker. 240 volts x 30 amps gives you three hours.
