The purchase is in addition to systems previously delivered and integrated into EVI medium-duty trucks and walk-in vans.

UQM Technologies president and CEO Eric Ridenour said the expansion of the company’s business with EVI into UPS vehicles represents a significant deployment of its higher power propulsion systems in the medium-duty commercial truck market and will drive revenue growth in this important segment.

UPS intends to deploy 100 all-electric vehicles in California early in this year, replacing older generation diesel trucks in the largest single deployment of zero tailpipe emission delivery vehicles in the state.

UPS estimates that the use of these vehicles will displace 126,000 gallons of fuel a year that would have been burned running diesel trucks.

The UQM PowerPhase HD Select 200 system includes a 200kW (268 horsepower)/900 N-m (664 ft-lbs) electric motor/generator and controller.

UQM Technologies is a developer and manufacturer of power-dense, high-efficiency electric motors, generators and power electronic controllers for the automotive, aerospace, military and industrial markets.
