ULTRACAPACITORS
SMART METERS AND AMR
APPLICATION BRIEF
Keep data flowing, even when power isn’t.
The smart grid requires next-generation metrology and sensing
to provide utilities and customers accurate and fail-safe data communication from an ever-increasing number
of locations.
The demand for enhanced connectedness, dependability and security is rapidly driving the development of
more powerful, outage-proof smart meter and AMR technologies based on Maxwell ultracapacitors. Maxwell
is proud to offer an extensive product line to address the robust needs of the metering market, enabling key
functionality such as data delivery even when power is lost. Benefits of Maxwell ultracapacitors in gas, water,
and electricity smart meters include:
Keep critical information and functions accessible in
the event of primary power loss
Reduce or eliminate battery maintenance and
replacement costs
Long lifetime and reliable operation in temperatures
ranging from –40° to +85°C with derated voltage
down from 2.7V to 2.3V*
XP: 3X lifetime improvement under biased humidity
testing (at 2.7V, 60°C, 90% RH) versus standard
Maxwell ultracapacitors
Compliant with UL, RoHS, and REACH requirements

APPLICATION BRIEF
Background
Ultracapacitors
Ultracapacitors are energy storage devices that provide
burst power for applications requiring high power functions.
Unlike batteries, which store energy via chemical
reaction, ultracapacitors store energy by electrostatically
(physically) separating positive and negative charges. The
ultracapacitor’s electrostatic energy storage permits the
device to be rapidly charged and discharged for hundreds
of thousands of cycles,
*
as compared to batteries, which
typically perform only hundreds or thousands of charge/
discharge cycles. Ultracapacitors are a reliable, energy-
efficient and cost-effective solution for storing energy.
Maxwell Technologies is the global leader in ultracapacitor
technology and is changing the way energy is used and
stored, with over 50 million cells deployed in the field into
applications such as grid energy storage, renewable energy
generation, automotive, and consumer electronics. Our
global R&D, manufacturing, and field support capabilities
allow us to deliver unsurpassed value to our customers
from early design to solution launch.
