‘Work Right the First Time’
Kollmorgen is talking up its role on the HEVT VT-REX crossover hybrid electric, Virginia Tech’s winning entry in the 2011 EcoCAR Challenge, a three-year collegiate advanced vehicle technology engineering competition with sponsors including General Motors – which donates the starter vehicles and provides ongoing support to the student teams.
Virginia Tech needed a belt alternator starter, Kollmorgen reports, with specific requirements including a 320-volt DC motor/generator able to generate 2 kilowatts of battery charging power at high RPM, and 60Nm (44 foot pounds) of torque to start the vehicle’s 2.4-liter engine.
The Kollmorgen system boasts “a unique configuration that consists of an induction motor/generator electro-magnetic package,” Kollmorgen says. “The motor/generator is used as the primary starting source to start the engine through the belt system. When the vehicle is idling, the generator provides power to charge the battery and powers any peripheral components on the vehicle.”
‘Robust and Flexible Electric Power’
“The partnership with Virginia Tech illustrates our ability to deliver robust and flexible electric power generation solutions that provide all the On Board Vehicle Power needed to operate heavier duty electrical equipment on defense vehicles, utility trucks, construction and agricultural vehicles, refrigeration trucks, buses, lift trucks and more,” Kollmorgen engineering VP John Boyland said in a release.
“Of primary significance in this particular application was Kollmorgen’s ability to quickly deliver and place a BAS system into a larger vehicle system, collaborate with the team at Virginia Tech to make sure it integrated within the complexity of the entire vehicle system, and to have it work right the first time,” Boyland said.
At the recent U.S. Army-Calstart HTUF 2011 show in Baltimore, Kollmorgen promoted a second-generation inverter family for commercial hybrid and electric vehicles (F&F, October 17).
Other firms supporting Virginia Tech’s HEVT VT-REX project included lithium battery supplier A123 (NASDAQ:AONE) and UQM Technologies (AMEX:UQM) for a rear traction motor. The Virginia Tech team took first place in year three of the 2011 EcoCAR Challenge, besting teams from Ohio State, the University of Waterloo, Penn State, the Missouri University of Science and Technology, and Mississippi State.
