High-Voltage Electric Drive for Heavier Duty Applications
Colorado’s UQM Technologies has introduced a new and more powerful electric vehicle driveline, the PowerPhase HD 250, for high-voltage electric and hybrid-electric vehicles, including heavy commercial truck and transit buses, and marine vessels.
“The PowerPhase HD 250 provides an ideal solution for trucks and buses that are designed to operate at voltages between 450 and 750 volts,” UQM president and CEO Eric Ridenour said in a release.
“Higher operating voltage creates lower operating current, enabling lower weight or lower resistance losses in vehicle wiring, and this is an architecture choice for some manufacturers’ electrified vehicles,” said engineering VP Jon Lutz.
335 Peak Horsepower
The PowerPhase HD 250 produces 900 Nm of peak torque (900 newton meters or 664 foot-pounds) and 250 kilowatts (335 horsepower) of peak power. UQM claims up to 95% energy conversion efficiency for the PowerPhase HD 250. It features an optimized permanent magnet motor/generator and a full-featured DSP – digital signal processor-based controller.
UQM’s PowerPhase customers include Hino for electric city buses, Proterra for electric transit buses, EVI/Electric Vehicles International for medium-duty trucks and walk-in vans, Zenith Motors for electric vans, Boulder Electric Vehicle for commercial vehicles, and ReGen Nautic marine propulsion systems.
Separately, UQM noted this week that pioneering electric aviation pilot Chip Yates set Guinness World Records for climb to altitude and speed (exceeding 200 mph) at the Capital Air Show in Sacramento. His aircraft is powered by UQM PowerPhase motor and controller.
