From the Laboratory to the Roadway: Aggie Bus Uses First of a Kind Inductive
Charging System

LOGAN, Utah, Nov. 15, 2012 /PRNewswire-USNewswire/ -- Utah State University
announced today that it has demonstrated a first-of-its-kind electric bus that
is charged through wireless charging technology.

The Aggie Bus rolled onto the streets carrying passengers today; just 16
months after USU demonstrated the first high-power, high-efficiency wireless
power transfer system capable of transferring enough energy to quickly charge
an electric vehicle. In July 2011, the USU Research Foundation demonstrated
90 percent electrical transfer efficiency of five kilowatts over an air gap of
10 inches. The demonstration validated that electric vehicles can efficiently
be charged with wireless technology.

USU's Wireless Power Transfer team, in cooperation with the Utah Science
Technology and Research initiative's Advanced Transportation Institute at USU,
has designed a more efficient way to meet the nation's transportation needs.
By carefully applying a mix of modern advances in engineering and Nikola
Tesla's principles of induction, USU engineer Hunter Wu and his team have
solved one of today's vexing problems in WPT. Their research has led to the
development of a robust prototype, which has been fitted to the Aggie Bus. The
prototype transfers power over an air gap where no physical contact is
required. Wireless power transfer technology delivers a multitude of benefits
to consumers that include greater reliability due to no moving parts or cords,
added convenience through the elimination of plug-in charging, the assurance
of safety by removing the risk of electrocution and aesthetically pleasing
devices as a result of no visible wiring.

USU's Aggie Bus has achieved several significant milestones. It is the first
bus developed and designed by a North American organization that is charged
with wireless power transfer technology and is the world's first electric bus
with WPT technology combining the three following performance metrics: A
power level up to 25 kilowatts, greater than 90 percent efficiency from the
power grid to the battery and a maximum misalignment of up to six inches.

"The unveiling of the Aggie Bus today is a historic achievement and a great
leap forward in the science and engineering related to electric vehicles,"
said Robert T. Behunin, Ph.D., USU vice president of commercialization and
regional development. "As a result of the work done by Utah State engineers,
scientists and partners, EV owners and operators will now be able to simply
drive over a pad in the ground to recharge their batteries, the benefits of
which reach far beyond convenience."

WAVE Inc., a Utah State University spin-out company, worked in cooperation
with the USTAR Advanced Transportation Institute to develop the Aggie Bus.
WAVE tackles the problem of heavy and expensive electric vehicle batteries
through wireless power that transfers electricity between vehicles and the
roadway. The Aggie Bus represents a market-ready product that will be used to
retire significant technical risk as WAVE moves onto full-scale projects next
year. WAVE, in partnership with the Utah Transit Authority, will launch its
first commercial demonstration in mid-2013 on the University of Utah's campus.
It will feature a 40-foot transit bus on a public transit route and an
increase in wireless power transfer charging from 25 kilowatts to 50
kilowatts. The project has been funded by a $2.7 million TIGGER grant from the
Federal Transit Administration and the University of Utah which purchased the
bus. WAVE intends to deliver a commercially ready product that operates with
the same reliability as current public transit bus options, including diesel
and compressed natural gas buses.

"Current battery limitations prevent an all-electric transit bus from
operating all day from an overnight charge. WAVE solves that problem by
charging the bus wirelessly during its daily operations when the bus stops to
load and off-load passengers," said Wesley Smith, CEO of WAVE. "This
technology makes electric buses competitive with their diesel hybrid and CNG

Utah State University has refashioned the way in which it conducts its
technology transfer operation. The office of Commercial Enterprises, a
division of Commercialization and Regional Development, provides a
one-stop-shop for industry partnership and intellectual property development.
The Utah Science Technology and Research initiative is an innovative and
far-reaching initiative of the Utah legislature to bolster Utah's high-tech
economy by investing in university research programs and recruiting new, high
caliber faculty. Utah State's wireless power transfer team is a significant
part of USU's USTAR portfolio.
