General Motors unveiled at the Detroit Auto Show a further glimpse at the potential of electric
The Converj Concept enables up to 40 miles of gas- and emissions-free electric driving with extended-range capability of hundreds of miles. The Cadillac Converj’s Voltec electric propulsion system is made up of a 16-kWh, T-shaped battery, an electric drive unit, and a four-cylinder engine-generator. It uses electricity as its primary source to drive the car. A thermally managed battery pack contains more than 220 lithium-ion cells. It takes less than three hours to recharge the battery at 240V, or about eight hours from a 120V outlet.
