‘This Could Be Big’ drives bigger interest in MTSU hybrid

This could be big? Overnight, it’s become huge for MTSU engineering technology professor Dr. Charles Perry.

Television journalist Bill Weir and the ABC News/Yahoo! News “This Could Be Big” online collaboration has rocketed interest in Perry’s plug-in hybrid retrofit kit motor project into a new orbit.

The Sept. 6 “This Could Be Big” posting at the ABC News/Yahoo! News page had already generated more than 1,300 comments from online viewers before noon EDT today. (You can read the post by clicking on the graphic at right.)

Perry and a student-centered five-member team saw gas mileage increase anywhere from 50 to 100 percent on a 1994 Honda station wagon equipped with laboratory prototype plug-in hybrid capability.

The Honda, a research vehicle, has been retrofitted with electric motors in each rear wheel and a large lithium ion battery mounted in the rear of the vehicle.

As lithium-battery technology improves, Perry said, the battery size will be reduced in production models. The professor added that he hopes the retrofit kit will cost $3,000 when it’s eventually mass produced.

“This is just amazing,” Perry said of the buzz created by the Yahoo! video and an early-summer release to Newswise, a source that reaches journalists all over the world.

“Everybody loves the idea. Everybody wants it.”

The video has has had 94,381 YouTube hits to date, and emails have been pouring in from around the world.

“I don’t know how many I’ve had,” Perry said, noting that messages have come from “India, Sri Lanka, Syria and all over the country.”

Perry also has been busy on the phone. The Yahoo! video generated a phone call from Cheryl Hanson of Prior Lake, Minn., 25 miles south of Minneapolis, who called on behalf of her husband, Mark, a mechanic for 30 years.

“The economy’s been such that we’re building our own business now,” Cheryl Hanson said. “You guys are doing great things. We saw the video and are super excited. It seems like a good fit and skill set for what we’re wanting to do.”

ABC’s Weir interviewed Perry, who serves as the Russell Chair of Manufacturing Excellence in MTSU’s Department of Engineering Technology, on Sept. 4 via Skype in the Telecommunications Building. Weir is co-anchor of ABC’s “Nightline.”

“I just don’t know where this is going to go,” said Perry, who has been working with Lou Svendsen, Tennessee Board of Regents university counsel, to approach companies with both U.S. and worldwide fleets of vehicles, especially those “interested in green technology, reducing the carbon footprint and savings in fuel costs.”

Perry had 40 patents in a 28-year career with IBM before coming to MTSU. He and his student-centered team have landed two U.S. patents for this project and are awaiting final approval on two more.

Plug-In Hybrid Retrofit Kit designed for mileage savings

Powered by at least nine MTSU students’ work since 2008, Dr. Charles Perry continues driving toward success in the development of the plug-in hybrid retrofit kit for any car.

Students push Perry’s gas-saving project to next level

Perry is now talking with several potential investors — companies with vehicle fleets — to solicit funds to build and demonstrate a manufacturing version of the plug-in hybrid technology.

The research Honda has been fitted with electric motors in each rear wheel and a large lithium-ion battery, which is mounted in the rear of the vehicle. As lithium-battery technology improves, Perry said, the battery size can be reduced in production models.

Switching on power to the two rear wheels’ electric motors made a huge difference by reducing the power required from the internal-combustion engine, he added.

“The whole point was to demonstrate the feasibility of adding the electrical motor to the rear wheel of the car without changing the brakes, bearings, suspension — anything mechanical,” Perry said.

The technology’s gas-saving principle uses an electric motor to supplement the power coming from the internal combustion engine. You can watch Perry explaining the process in the video above.

All nine students, who now have graduated with bachelor’s or master’s degrees, came from MTSU’s Department of Engineering Technology. Each has provided unique talents and abilities to bring the project to fruition.

The most recent group includes:

  • Jay Perry (no relation to Charles Perry), mechanical design/build and drawing;
  • Brent Brubaker, electrical design and build;
  • Ken Gendrich, programming;
  • Brandon Cromwell, computer numerical-control machining; and
  • Suneth Wattage, finite-elements analysis modeling.

Alex Kirchoff ‘s drawing skills, Ken Garrett’s electrical design/build expertise, Brian Mastley’s mechanical-build talent and David Gray’s mechanical-machining experience helped in the first years of the wheel-hub project.

Jay Perry views the rotor he has removed from the stator, which is attached to the axle bearings. In the entire process, nothing alters the car'€™s bearings, brakes or suspension.

“It was a huge honor to work on it,” said Brubaker, a May 2012 graduate. “I got to collaborate with some of the best minds —not only the other students, but the faculty.

“The wheel-hub motor is an answer to a problem. It’s innovative technology. You can take and bolt it on a car. When people see that, their eyes light up. They think it might cost a lot of money and are surprised when you tell them it might be $3,000. We have a lot of student projects that I have been a part of, but the wheel-hub was my favorite out of the whole thing.”

Jay Perry will remain heavily involved in the project this fall. Other students will join the team as plans develop.

Perry, who also is a professor of engineering technology, said the students’ contributions proved invaluable.

“We’ve had heavy student involvement,” Perry said. “One of our goals has been to utilize students in the building, testing and design. Nine students in the last five years very much were involved in all aspects of developing this technology.”

Team Perry also includes John Rozell, the ET department’s assistant director, and Rick Taylor, director of laboratories.

The plug-in hybrid retrofit kit is applied to a vehicle'€™s rear wheels. After switching on the traction motors, gas mileage can increase 50 to 100 percent.

Paul Martin III, an employee who left MTSU in October 2011 to work for Quality Industries in La Vergne, assisted Perry three years. He is the son of alumna and MTSU Foundation immediate past president Murray Martin. His father, alumnus Paul W. Martin Jr., and uncle, Lee Martin of Knoxville, donated $2 million toward the building of MTSU’s Paul W. Martin Sr. Honors Building.

Perry said three faculty members also played prominent roles in the project:

  • Dr. Chong Chen advised in the motor’s design and directed Wattage’s modeling work;
  • Dr. Richard Redditt oversaw the mechanical build of the earliest prototype of the wheel-hub motor; and
  • Dr. Ron McBride was a consultant and oversaw student involvement in the machine shop.

Perry said they have reached what industry insiders call “the valley of death” as they try to transfer the project’s technology from the laboratory to a commercial product.

“We have gained proof of concept in terms of feasibility,” he said. “We need quite a bit of money to have proof of product. What we’ve achieved is a demonstrated technology, not a proven technology. Investors want to see proven field-tested performance and reliability. We have to pass through this transition, from feasibility to true, viable product.”

Perry, who had 40 patents in a 28-year career with IBM before coming to MTSU, said a manufacturing partner has stepped forward “and is totally committed to us” and will accompany him to anticipated upcoming presentations.

Perry said Lou Svendsen, university counsel with the Tennessee Board of Regents, will join him in approaching companies that have both U.S. and worldwide fleets of vehicles, especially those “interested in green technology, reducing carbon footprint and savings in fuel costs.”
