Maxwell Technologies Selects Ansoft's SIMPLORER as Preferred Platform for Ultracapacitor Component Model Library

   Companies collaborate to create a model library of ultracapacitor
 components for next-generation energy-storage systems for automotive,
                 industrial and aerospace applications

   Maxwell Technologies Inc. (NASDAQ:MXWL) and Ansoft Corporation
(NASDAQ:ANST) today announced that they will develop a model library
of Maxwell Technologies' BOOSTCAP(R) ultracapacitor cells and
multi-cell modules using the VHDL-AMS modeling language for use in
Ansoft's SIMPLORER(R). Maxwell Technologies selected SIMPLORER based
on the strength of its VHDL-AMS simulation capabilities and on
Ansoft's leading position and focus on providing high-performance,
system-simulation solutions to the automotive, aerospace and
industrial power markets.
   "The library will contain a wide range of ultracapacitor cell and
module products to ensure that our current and future customers will
have the necessary elements to develop the next generation of
energy-storage systems for automotive, industrial and other
applications," said Dr. John M. Miller, Maxwell's vice president,
advanced transportation applications. "We chose the SIMPLORER platform
because it provides robust modeling capability, is widely used in our
target markets and adheres to the VHDL-AMS modeling standard."
   Ultracapacitors are ultra-high-capacity energy-storage devices
that deliver bursts of high power and recharge rapidly from any energy
source over hundreds of thousands of cycles. BOOSTCAP ultracapacitor
products are the world's leading high-performance production
ultracapacitors. Compared to batteries, BOOSTCAP cells deliver up to
10 times the power, last up to 10 times as long, operate more reliably
in high- and low-temperature conditions, require far less maintenance
and reduce environmental issues associated with battery disposal.
Ultracapacitors produce cleaner and more fuel-efficient
hybrid-electric/internal-combustion buses, trucks and automobiles.
Ultracapacitor technology is ideal for powering initial acceleration,
operating electrical subsystems and regenerative braking.
   "Hybrid-electric vehicles and alternative-energy research and
development are of great interest to our SIMPLORER customers," said
Dr. Marius Rosu, Ansoft's group leader, SIMPLORER modeling.
   "For researchers to have access to accurate VHDL-AMS models of
ultracapacitors directly from Maxwell Technologies will make them more
productive and speed the pace of their research."
   VHDL-AMS is the IEEE-endorsed standard modeling language (standard
1076.1) created to provide a general-purpose, open language for
analog-mixed-signal designs. Models that adhere to this standard are
useable in all simulation tools that adhere to the VHDL-AMS standard.
