SAN DIEGO, April 9, 2014

SAN DIEGO, April 9, 2014 /PRNewswire/ --Maxwell Technologies, Inc. (Nasdaq:
MXWL) announced today that it is supplying ultracapacitors to ABB, the global
leader in power and automation solutions, for ABB's recent contract win to
upgrade Philadelphia area rail lines. As previously announced, ABB will
install a hybrid version of its high-efficiency ENVILINE™ energy recovery and
storage system for the Southeast Pennsylvania Transit Authority's (SEPTA)
light rail system serving the greater Philadelphia area.

ABB installed a battery-based ENVILINE braking energy recuperation system in a
substation of SEPTA in 2012 and has now incorporated Maxwell ultracapacitors
in a new hybrid configuration to increase energy recovery efficiency and
extend battery life. In addition to reducing SEPTA rail vehicles' consumption
of grid-supplied electrical energy by 10 to 20 percent, the system enables
SEPTA to provide frequency regulation services on the PJM Interconnection
Network, a regional transmission organization (RTO) that coordinates the
movement of wholesale electricity in all or parts of Delaware, Illinois,
Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio,
Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.

"By incorporating ultracapacitors, we will recover more braking energy,
produce higher revenues from frequency regulation and extend battery life,"
said Jacques Poulin, ABB's product manager for energy storage and rail. "The
SEPTA model is the first of its kind in the world, going beyond the recovery
of braking energy by also helping the electricity grid to be more stable and
efficient with fast regulation support."

Braking energy recuperation systems in electric and hybrid vehicles save fuel
and electrical energy by using resistance from the electric motor to stop the
vehicle, thereby converting kinetic energy that would be wasted in a
conventional friction-based braking system into stored electrical energy.
Ultracapacitors' rapid charge/discharge characteristics uniquely enable them
to capture and store more energy during each braking event than battery-based
systems, which have limited ability to absorb energy in the few seconds
required to stop a vehicle.

"Transportation is the world's largest energy consumer, so deployment of
systems that conserve energy and reduce fuel consumption and emissions are
creating tremendous long-term growth opportunities for our leading
ultracapacitor technologies," said John Warwick, Maxwell's interim president
and CEO.

Unlike batteries, which produce and store energy by means of a chemical
reaction, ultracapacitors store energy in an electric field. This
electrostatic energy storage mechanism enables ultracapacitors to charge and
discharge in as little as fractions of a second, perform normally over a broad
temperature range (-40°C to +65°C), operate reliably through one million or
more charge/discharge cycles and resist shock and vibration. Maxwell offers
ultracapacitor cells ranging in capacitance from one to 3,000 farads and
multi-cell modules ranging from 16 to 160 volts. For more information on
