China Vies to Be World’s Leader in Electric Cars By KEITH BRADSHER Published: April 1, 2009

TIANJIN, China — Chinese leaders aimed at turning the country into one of the leading producers of three years, and making it the world leader in electric cars and buses after that.Skip to next paragraph

Chinese leaders aimed at turning the country into one of the leading producers of three years.

At the Tianjin-Qingyuan Electric Vehicle Company, a worker assembles a block of battery packs

The goal, which radiates from the very top of the Chinese government,

suggests that Detroit’s Big Three, already struggling to stay alive, will face even stiffer foreign competition on the next field of automotive technology than they do today.

“China is well positioned to lead in this,” said David Tulauskas, director of China government policy at General Motors.

To some extent, China is making a virtue of a liability. It is behind the United States, Japan and other countries when it comes to making gas-powered vehicles, but by skipping the current technology, China the next.

Japan is the market leader in on both electricity and gasoline, with cars like the Toyota Prius and Honda Insight. The United States a laggard in alternative vehicles. G.M.’s plug-in sale next year, and will be assembled in Michigan using rechargeable batteries imported from LG in South Korea.

China’s intention, in addition to creating a world-leading industry that will produce jobs and exports, is to reduce urban pollution and decrease its dependence on oil, which comes from the Mideast and travels over sea routes controlled by the United States Navy.

But electric vehicles may do little to clear the country’s smog-darkened sky or

curb its rapidly rising emissions of global warming gases. China gets three-fourths of its electricity from coal, which produces more soot and more greenhouse gases than other fuels.

A report by McKinsey & Company last autumn estimated that replacing a gasoline-powered car with a similar-size electric car in China would reduce greenhouse emissions by only 19 percent. It would reduce urban pollution, located outside cities.

Beyond manufacturing, subsidies of up to $8,800 are being offered to taxi fleets and local government agencies in 13 Chinese cities for each ordered to set up electric car charging stations in Beijing, Shanghai and Tianjin.

Government research subsidies for electric car designs are increasing rapidly. And an interagency panel is planning tax credits for consumers who buy alternative energy vehicles.

a consulting firm that does forecasts for automakers, predicts that Japan and South Korea together will be producing 1.1 million and North America will be The United States Department of Energy $25 billion program to develop electric-powered cars and improve battery technology, and will receive another $2 billion for battery development as part of the economic stimulus program enacted by Congress.

Premier Wen Jiabao Gang, a Shanghai-born former Audi auto engineer in Germany who later became the chief scientist for the Chinese government’s research panel on electric vehicles.

Mr. Wan is the first minister in at least three decades who is not a member of the Communist Party.

And Premier Wen connection to the electric car industry. He was born and grew up Tianjin, the longtime capital of China’s battery industry, 70 miles southeast of Beijing.

Tianjin the six years since Mr. Wen became premier. It now service (to Beijing), a new Airbus factory and an immaculate new airport. Tianjin -Qingyuan Electric Vehicle Company.

Electric cars China. Intercity driving is rare. Commutes are fairly short and frequently at low speeds because of traffic jams. So the limitations of all-electric cars — the latest models in China charges — are less of a problem.

First-time car buyers also make up four-fifths of the Chinese market, and these

buyers accustomed to the greater power and range of gasoline-powered cars.

But the electric car industry faces several obstacles Chinese live in apartments, and cannot install recharging devices in driveways, so more public charging centers need to be set up.

Rechargeable lithium-ion batteries also in China. Counterfeit lithium-ion batteries in cellphones occasionally explode, causing injuries. And Sony batteries in laptops in 2006 and 2008 after some overheated and caught fire or exploded.

These safety problems associated with lithium-ion cobalt batteries, phosphate batteries now being adapted to automotive use.

The tougher challenge is that all lithium-ion batteries are expensive, whether made with cobalt or phosphate. That will be a and put on the Olympics: immense amounts of energy, money and people.

BYD equal number of battery engineers, most of them living at its Shenzhen in a cluster of 15 yellow apartment buildings, each 18 stories less than $600 a month, including benefits.

When Tianjin-Qingyuan puts its entirely battery-powered Saibao midsize sedan on sale this autumn, the body will come from a sedan that normally sells for $14,600 when equipped with a gasoline engine. But the engine and gas tank will be replaced with a $14,000 battery pack and electric motor, said Wu Zhixin, the company’s general manager.

That means the retail price will nearly double, to almost $30,000. Even if the government awards the maximum subsidy of $8,800 to buyers, that is a could drive down the cost of the battery pac …… 此处隐藏:5615字,全部文档内容请下载后查看。喜欢就下载吧 ……
