UQM Technologies Receives Order to Refresh PowerPhase Components in Denver RTD Hybrid Buses

UQM Technologies UQM and the Denver Regional Transportation District (RTD) announced today that UQM will begin a refurbishment program on the generators and motor controllers used in the agency's fleet of hybrid buses. The original units being refurbished far exceeded their expected life and this program will allow additional running time for the fleet of buses, which operate seven days a week in downtown Denver. These 30 hybrid buses have covered more than a million miles in daily service since 2004. The buses use UQM PowerPhase Select® electric generators and controllers as part of the hybrid powertrain. “This pioneering fleet of hybrid buses was one of the earliest hybrid vehicle programs in the country, and the amount of miles these hybrid systems have traveled over nearly a decade is impressive,” said Eric R. Ridenour, President and Chief Executive Officer of UQM Technologies, Inc. “This speaks well for the durability of UQM components in real world usage, and we look forward to providing this service and our expertise to the Denver RTD.” As part of the refresh, each UQM component in the hybrid bus systems will be thoroughly inspected and worn parts replaced, returning the units to near-new condition. Each refurbished unit will then be run through a full set of final testing to ensure that they are ready for many more miles of trouble-free operation. All 30 shuttle buses are expected to be refreshed over the next two years. UQM is also powering Hino electric city buses, Proterra electric composite transit buses, Electric Vehicles International all-electric medium-duty trucks and Boulder EV delivery vans. UQM has recently expanded its product offerings for full-electric buses and commercial vehicles with the introduction of the PowerPhase HD® 220.
