GM testing Lithium-ion batteries for the Volt
Still hoping to reach their in-showroom target of 2010, General Motors has started testing lithium-ion batteries for the Chevrolet Volt. This announcement came from Vice Chairman, Bob Lutz. It is widely accepted that this target is already in question with the expected launch to be in November of that year. With over two years to go, GM is already saying that the launch will come down to the wire.
The key to the fuel efficiency of the Volt is the E-Flex electric powertrain, which relies on its battery. While GM has been testing lithium-ion batteries for a while, this is the first sign of one being used in a on-road vehicle, marking a big step in bringing the Volt to market – something that will be a big help in the fight against global warming, and is sure to boost GM’s sales.
The exact fuel efficiency of the Volt is as yet undetermined as it will rely heavily on the battery, but Lutz has said the vehicle has a “pretty good shot of getting over 100 mpg”. With more and more renewable energy sources being added to the portfolios of the big utility companies, a plug in car will result in far fewer carbon emissions than any car on the road today.
Despite the clear benefits of the E-Flex system, GM is not planning on using it in a compact car. But if regulations gets passed requiring better fuel efficiencies across their fleet – which seems likely based on what the presidential candidates have said – GM would consider using the efficient technology in pickups.
