Toyota Adopts Tesla Battery Strategy for Electric

Toyota Motor Corp.. AG and Bayerische Motoren Werke AG are to laptops for a cheaper way to power electric cars — and sales.

Automakers are testing of lithium-ion batteries assembled by Valley startup Tesla Inc. costing less bigger, car-only batteries by General Motors Co.. Motor Co. and Mitsubishi Motors A pack of 6,831 cylinder-shaped made by Panasonic Corp. Tesla’s $109,000 Roadster car for up to 245 miles per charge.

The car industry help lithium-ion battery more than triple to 5 trillion yen ($60 billion) in a from 1.5 trillion yen in the year in March, according to Sanyo Co. the world’s biggest maker of the Rechargeable consumer-electronics batteries from an economy of scale may help cut manufacturing costs and prices in the nascent electric-car said Koji Endo. a analyst at Advanced Research

“It may lead to the total component of an electric car getting lower that of a gasoline car,” said. “As the cost lowers, be more likelihood that prices of electric cars drop.”

Chevy Volt, Leaf

EV prices are higher three-quarters of the autos now sold, to Bloomberg New Energy Finance, GM’s Chevrolet Volt for $41,000 and Nissan’s Leaf for Electric vehicles cost twice as much to produce as cars because the batteries are so according to consultant Frost Inc.

Sales of EVs and hybrids, plug-in models, will about 954,000 worldwide year, or about 2.2 percent of all car J.D. Power and Associates, an forecaster in Westlake Village, estimated in October.

Government may help boost sales of hybrids and EVs to 9 percent of auto in 2020, Bloomberg New Energy estimated last month.

Panasonic. the majority shareholder in is the main supplier of lithium-ion to Tesla and last month a $30 million stake in the Palo California, company. Toyota and also own Tesla stakes.

The larger lithium batteries about $700-$800 per kilowatt to produce, while mass-produced using small laptop may cost $200, said Eberhard. Tesla’s founder and chief executive officer.

“It’s a much more approach,” he said. “There’s a advantage in terms of economy of

‘Full-Line Maker’

Factories small cells are running at capacity, Eberhard said. also benefits EV makers who have the resources to develop own batteries, said Menahem president of Advanced Automotive a consulting firm in Oregon California.

GM partners with Korea’s LG Chem Ltd. for the pack, and Nissan partners NEC Corp.. Japan’s biggest maker, for the Leaf.

Toyota, the largest automaker. is working Tesla on the electric RAV4, its plug-in Prius hybrid and a electric car planned for 2012 larger batteries.

“When the decides ‘This is the car I want,’ we to be that full-line maker who has the for that customer,” Toyota Akio Toyoda said. “By both car batteries and laptop we are able to provide customers a wider variety of choice.”

The alliances with Toyota and helped Tesla generate an public offering in June raised about $226

Battery Recalls

Tesla’s have surged more 80 percent this year, with an 11 percent increase in the 1000 Index, even the company has delivered fewer 1,500 Roadsters since

Shares of Toyota have 15 percent this year, than a 3 percent decline by benchmark Nikkei 225 Stock

A123 Systems Inc.. a Massachusetts-based lithium-ion battery part-owned by General Electric also is promoting small, cells originally designed for tools.

Lithium-ion batteries in electronics have a history of because of overheating that can a fire. Nokia Oyj. the largest mobile-phone maker, in 2007 to replace as many as 46 Panasonic phone batteries.

Panasonic now uses an insulator between electrodes to limit the of overheating, said Yuji a spokesman for the battery unit.

Out of Hell’

Sony Corp. 9.6 million lithium-ion cells in because metal particles got into cells during could cause short and overheating.

That remains an for Takenobu Inaba, 27, who was shopping at a showroom in Yokohama, Japan. He he would choose a gasoline-powered car an electric one.

“When I Tesla’s car has a huge battery consisting of those used in electronics, my image of the car was ruined,” said. “I’m still that those lithium-ion may explode.”

Roadster owner Painter said he isn’t about what’s under the and hasn’t noticed any degradation in the since his 2008 purchase.

“I’ve never been wanting on the batteries,” said chief executive officer of Inc. an automotive- sales company in Santa Monica, “I step on the pedal and it goes a bat out of hell.”
