UQM TECHNOLOGIES, INC. (NYSE Amex:UQM), a developer of alternative energy technologies, announced today that it is collaborating with BorgWarner (NYSE:BWA) on electric powertrain products for all-electric and hybrid-electric passenger automobiles. Initially, the companies are working together to integrate UQM Technologies’ PowerPhase® electric propulsion system with BorgWarner’s 31-03 eGearDrive™ transmission for the all-electric CODA front-wheel drive five-passenger sedan, scheduled for introduction in the California market in mid-2010.
The UQM® PowerPhase® electric propulsion system has a peak power rating of 100 kW (134 horsepower) and a continuous power rating of 45 kW (60 horsepower). It delivers peak torque of 300 Nm (221 ft-lbs) and continuous torque of 160 Nm (118 ft-lbs). With a diameter of only 280 mm (11 inches) and a weight of 46 kg (102 lbs), this motor will fit easily in a wide range of passenger vehicles, including subcompacts. The system also features optimized four-quadrant performance, dynamic torque, speed and voltage control, and system energy efficiency of over 90 percent across a substantial portion of its power curve.
The BorgWarner 31-03 eGearDrive™ transmission is ideally suited for mid-range electric vehicles on either front-wheel drive or rear-wheel drive transverse driveline applications. The single-speed 31-03 uses a unique flange and coupling for adaptation to the PowerPhase® motor housing to accommodate input shaft speeds of up to 14,000 rpm with a wide range of reduction ratios and very high operating efficiency. The 31-03 is also available with an optional ePark feature, an electronically actuated park lock system.
An electric powertrain consisting of a UQM® PowerPhase® electric propulsion system mated with the BorgWarner 31-03 eGearDrive™ transmission provides a compact and torque-dense package, delivering nearly 2,000 Nm (1,500 ft-lbs) of torque with a gear ratio of approximately 6.5 to 1. The package will propel a mid-size passenger vehicle at highway speeds with economical, high powertrain efficiency.
“Collaborating with suppliers such as UQM Technologies will allow us to broaden the reach of our high efficiency, purpose-built electric drive transmissions, accelerating vehicle integration for fast-to-market implementation,” said John Sanderson, President and General Manager, BorgWarner Drivetrain Systems. “We believe the pairing of our high efficiency transmission with UQM Technologies’ high performance electric propulsion systems present an extraordinary performance and value proposition to vehicle makers.”
“We are pleased to collaborate with BorgWarner, a world leader in powertrain technologies, to offer vehicle makers a turn-key electric powertrain that delivers exceptional vehicle performance at high operating efficiencies,” said William G. Rankin, UQM Technologies’ President and Chief Executive Officer. “BorgWarner’s global presence will bring a higher level of visibility to our electric propulsion system products.”
