Kollmorgen quickly delivers electric power generation system that satisfies all Virginia Tech's hybrid vehicle operating requirements, while integrating within the complexity of the entire vehicle system
RADFORD, VA - Kollmorgen collaborated earlier in the year with Virginia Tech's Hybrid Electric Vehicle Team (HEVT) to develop and integrate the electric power generation system for the HEVT VT-REX hybrid vehicle. The Kollmorgen solution combines standard offerings comprised of mechanics and electro-magnetic technology to satisfy all the requirements put forth by the Virginia Tech team. VT-REX is Virginia Tech's entry into the 2011 EcoCAR Challenge, a three-year collegiate advanced vehicle technology engineering competition. Virginia Tech placed first overall, and received numerous additional awards related to hybrid vehicle design and performance.
For this project Virginia Tech required a power generation system (BAS [Belt Alternator Starter]) that satisfied hybrid vehicle requirements for highway vehicles. Specific requirements included a 320Vdc motor/generator with the ability to generate 2kW of battery charging power at high RPM, and provide 60Nm of torque to start the engine. The system also had to withstand all of the challenging environmental conditions that highway vehicles are exposed to.
The electric power generation system supplied by Kollmorgen is a unique configuration that consists of an induction motor/generator electro-magnetic package. 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.
"While consumer automotive hybrids are outside Kollmorgen's strategic focus, 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," says John Boyland, Vice President, Engineering, Kollmorgen. "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."
Kollmorgen has introduced a power generation platform specifically engineered to satisfy the rigorous commercial and military electric power needs. Kollmorgen's unique low voltage Power Generation System consists of flexible power electronics that support multiple vehicle motor/generator configurations and mild hybrid capability, providing the power that OEMs need at the voltage they want. And unlike vendors who supply just high or low voltage systems, Kollmorgen is uniquely positioned to serve as a one-stop shop for heavy-duty vehicle OEMs who have a wide variety of power needs within a single vehicle, and/or across vehicle platforms. The Power Generation System has been named a 2011 Golden Mousetrap best new product finalist by the editors of Design News magazine.
"As application demands evolve, commercial and military defense vehicle OEMs adjust their designs and need to find the optimum voltage to deliver the desired power, so working with a single supplier who can deliver low or high voltage solutions, or anything in between, is a huge advantage," explains Boyland.
EcoCAR: The NeXt Challenge is a three-year collegiate advanced vehicle technology engineering competition established by the United States Department of Energy (DOE) and General Motors (GM), and managed by Argonne National Laboratory.
The competition challenges 16 universities across North America to reduce the environmental impact of vehicles by minimizing the vehicle's fuel consumption and reducing its emissions while retaining the vehicle's performance, safety and consumer appeal. Students use a real-world engineering process to design and integrate their advanced technology solutions into a GM-donated vehicle.
Kollmorgen is a leading provider of power generation and motion systems for OEMs around the globe. Through world-class engineering knowledge, industry-leading quality and deep expertise in linking and integrating standard and custom products, Kollmorgen delivers breakthrough solutions that are unmatched in performance, reliability and ease-of-use, giving vehicle and machine builders an irrefutable marketplace advantage.
