| The Nissan Motor Co. - Renault SA auto alliance Better Place is likely to be able to overcome a key obstacle to the adoption of electric cars as a California-based company demonstrated a new battery-swapping technology. |
Founded two years ago, Better Place unveiled a model of its battery switching station in this port city near Tokyo, seeking to garner enthusiasm for its one-of-a-kind technology among Japan's auto heavyweights, government officials and consumers.
The company is aiming to establish a ubiquitous network of charging posts, supplemented with a series of battery exchange stations where drivers traveling long distances can quickly swap a drained battery for a fully charged one, said CEO and founder Shai Agassi.
The exchange stations address one major complaint about electric cars that have stalled them at the experimental stage so far: the frequent, extended stops necessary to charge them.
"Most zero-emission cars have been experimental in nature, small in volume and expensive to say the least," Agassi said. "And definitely not convenient. We were lacking those two elements - convenience and affordability."
Better Place's stations would have drivers back on the road with a new battery in as little as 40 seconds. They are designed to have a driver pull over an square underground platform that would reach up, remove the old battery from the belly of the vehicle and replace it with a new one.
Its "quick switch" model is being touted as among the most promising innovations for the development of emissions-free cars, which continue to face a number of barriers to mass market appeal.
Automakers still need to configure the cars' large lithium ion batteries for mass production and ensure they are long-lasting and safe. The vehicles themselves are still too expensive for the average consumer without hefty government incentives. And the troubled auto industry has yet to figure out which next-generation technologies will ultimately prevail in the market.
The Nissan Motor Co. - Renault SA auto alliance has teamed up with Better Place to build an electric vehicle network in Israel and Denmark.
Japan's No. 3 automaker is working to introduce plug-in electric vehicles in the U.S. in 2010 and mass market them globally two years later. It has no plans at this point to build quick-switch models outside of its announced projects with Better Place.
Nissan spokesman Alan Buddendeck described Better Place's battery exchange idea, which would rely on automakers producing cars with removable batteries, as "one important model." But it doesn't have to be the only one, Buddendeck said, noting the potential of home-based stations and high-speed charge networks.
Agassi says the stations will accommodate different battery and car models, and will cost about $500,000 to build - cheaper than a standard gas station, which can run $1 million to $2 million. For drivers, the cost of driving a 1 mile (kilometer) would be roughly equivalent to that of driving a gas-powered vehicle, he said, without giving specific figures.
