UQM Technologies Inc. says it is providing its PowerPhase electric-drive system for the Audi A1 e-tron extended-range electric vehicle (EV), which is the subject of late-stage R&D and testing in Germany this year.
These extended-range vehicles use the electric powertrain for propulsion and an internal combustion engine to charge the battery pack. The A1 e-tron will employ the PowerPhase Select 125 system, offering a maximum all-electric range of approximately 30 miles.
‘The key attributes of our electric motors and controllers offer the same advantages in extended-range electric vehicles as they do in electric-only applications,’ says Eric R. Ridenour, president and CEO of UQM Technologies. ‘Our higher-efficiency systems provide the potential for longer all-electric mode and an overall improved fuel economy in extended-range vehicles.’
