American Maglev Wins Contract to Retrofit 27 Vehicles with Energy-Saving

SAN DIEGO, April 23, 2013 /PRNewswire/ --Maxwell Technologies, Inc. (Nasdaq:
MXWL) announced today that it is supplying ultracapacitors for an
energy-saving braking energy recuperation system that American Maglev
Technology (AMT), is installing on light rail vehicles operated by the
Portland, Oregon area's Tri-County Metropolitan Transportation District


TriMet won a $4.2 million grant from the U.S. Department of Transportation's
Federal Transit Administration (FTA) Transit Investment for Greenhouse Gas and
Energy Reduction (TIGGER) program to improve the efficiency of its fleet of
101 light rail vehicles equipped with regenerative braking after determining
that the vehicles were able to use only about 70 percent of the energy
generated by braking.

In regenerative braking systems, the electric motor that propels an electric
or hybrid vehicle also does most of the braking. When the brakes are applied,
instead of employing a conventional friction-based braking process, the system
signals the electric motor to run in reverse mode, creating resistance to slow
the vehicle. An electric motor running backwards also acts as an electric
energy generator or dynamo that converts the kinetic energy of motion into
electrical energy that can be stored for reuse, improving efficiency.

In TriMet's system, energy generated by decelerating vehicles is fed into the
traction electrification system for use by other vehicles on the system.
TriMet is using the TIGGER funding to retrofit 27 vehicles with the American
Maglev-designed, ultracapacitor-based, energy storage system, which captures
and stores regenerative braking energy as it is generated, uses the stored
energy for acceleration, and releases surplus energy to other vehicles on the
system as needed. The 27 retrofitted vehicles are being paired with
non-capacitor equipped vehicles so that stored energy can be used by both

To measure and validate anticipated energy savings, TriMet will compare
in-service energy consumption data collected by on-board vehicle propulsion
computers before and after the retrofit. According to a bulletin published by
the FTA and prepared by the U.S. Department of Energy's National Renewable
Energy Laboratory (NREL), preliminary data collected by TriMet indicate that
the roof-mounted ultracapacitor-based energy storage systems will result in
annual energy savings of approximately 2.8 percent. The FTA bulletin may be

"The use of Maxwell's ultracapacitors in our Energy Storage Systems has
resulted in unprecedented energy savings as we strive to make light rail
vehicles greener and more energy efficient," said Tony J. Morris, the
president and CEO of AMT. "We see this as a new, enabling, sustainable
technology that can be applied in many other transportation environments."

"With their ability to charge and discharge in as little as fractions of a
second, ultracapacitors are highly efficient in capturing energy generated
during braking events that last only a few seconds and then quickly releasing
stored energy as needed for acceleration," said David Schramm, Maxwell's
president and CEO. "In addition to this and other rail installations,
fuel-efficiency and emission-reduction benefits are being realized by more
than 10,000 Maxwell ultracapacitor-equipped hybrid-electric transit buses in
daily operation around the world."
