<< A turbodiesel is far more efficient than an electric car. >>
May 28, 1997--- Energy Conversion Devices, Inc. ("ECD") (NASDAQ National Market:ENER) has received the final energy consumption data for the 1997 American Tour de Sol from the competition organizer, the Northeast Sustainable Energy Association ("NESEA"). The first place winner in the Production Category, a Solectria Force achieved the impressive equivalent of 130 miles per gallon (MPG) on range day, powered by Ovonic nickel metal hydride (NiMH) batteries. Range day, Wednesday, May 21, 1997, gave competitors the opportunity to drive the required 69 miles of the route, plus as many additional miles as they could with the remaining energy available in the batteries. The 28 KWh Ovonic NiMH battery pack with its superior specific energy, expressed as watt hour/kg (Wh/kg), achieved a range of 249 miles.
The "equivalent MPG" for the EV is based upon "oil well-to-wheel" efficiency, including central generating plant efficiency, power transmission losses, charging efficiency and mechanical drivetrain losses. The superior specific energy (Wh/kg) of the Ovonic NiMH battery and the efficiency of the Solectria drivetrain account for the differences in equivalent MPG between the EVs.
Also, the Prius electric hybrid already available in Japan is getting 80 MPG now.
