Gm ceo says it's been four years.
CEO Dan Akerson said at the staff meeting that the company is located in Newark, California --
Based on the Envia system, great breakthroughs have been made in the amount of Lithium Energy
Ion batteries can be maintained.
GM is sure the battery can travel 100 miles (160km)
Within a few years, he said.
He said it would probably double if he was lucky.
"I think we're better than 50 --
"50 opportunities," said Mr. Akerson, "to develop a car that runs 200 miles (320km)
"Charges," he said.
"This will change the rules of the game.
"GM's current electric vehicle, Chevrolet Volt, is charging about 56 km kilometers and has a small gasoline motor that powers the car's charging.
Few competitors own more than 160 km kilometers of electric vehicles.
Tesla's Model S can reach 480 km, but its batteries are much larger and more than double the price of the Volt.
Nissan's Leaf and Ford's Focus Electric vehicles both claim about 160 km miles, but this may vary depending on temperature, terrain and speed.
Earlier this year, Envia said it's next
Generation rechargeable Lithium
The energy density of ion batteries has reached a record high.
The company said the new battery could cut the price of electric vehicles by reducing the cost of the battery by half.
General Venture Capital Co. , Ltd. , the general Automobile Investment Department, has invested $7 m ($6. 6m)
January of 2011 into Envia.
The General Motors meeting was broadcast on a conference call to employees and lasted about an hour.
One participant allowed The Associated Press to listen.
In response to a question about GM's gas strategy, Akerson said: "These small companies don't know where to come from, they surprise you . "
Electric hybrid car
Mr. Akerson says the company is considering a hybrid
Electric vehicles, hydrogen fuel cells and gas vehicles, and the development of more efficient oilPower engine.
"We can't put all the chips on one bet," he said . ".
"We have to look at them all.
