controls charging rate based on grid conditions and aims to reduce
electricity cost for plug-in vehicles

Grid-friendly PEV charging solution delivers benefits to grid
operators and drivers
MONROVIA, Calif.--(BUSINESS WIRE)--
AeroVironment,
Inc. (NASDAQ: AVAV) and the United States Department of Energy's Pacific
Northwest National Laboratory (PNNL), managed by Battelle,
today announced a commercial license agreement for a technology that
supports widespread adoption of plug-in electric vehicles (PEVs) by
helping to stabilize the electrical grid -- the network of electricity
generation, transmission and distribution that powers the nation.

The technology may result in lower-cost electricity for plug-in vehicle
drivers due to the grid support functions provided during vehicle
charging. AeroVironment will use a portion of the licensed PNNL
technology in a new prototype version of its industry-leading Level II
charging systems.
Wahid Nawabi, AeroVironment senior vice president and general manager of
its Efficient Energy Systems (EES) business segment, said, "We are
working to broaden the adoption of plug-in vehicles to help achieve
America's environmental, economic and energy security goals. While
easily and reliably recharging PEVs, this grid-friendly charging system
will also improve grid performance, turning PEVs and their chargers into
a valuable solution to a broader challenge."
The licensed PNNL technology can help stabilize the electrical grid by
continuously monitoring the grid's alternating current (AC) frequency
and varying the vehicle charging rate in response. Additionally, in the
event of a rapid drop in grid frequency, the charging system stops
charging, providing a grid "shock absorber." Such rapid frequency drops,
while small in overall magnitude, indicate that a fault condition has
occurred somewhere on the grid and that there is an imbalance between
load and electricity generation. By reducing load the system can be
rebalanced.
Conventional power plants make continual power generation adjustments
based on precisely measured grid frequency in order to maintain a nearly
constant frequency of 60 cycles per second. As renewable generation
sources such as wind and solar grow in overall share, the overall
frequency-responsive generation capability provided by conventional
power plants is gradually decreasing. AeroVironment and PNNL's
frequency-responsive technology brings this same grid frequency support
capability to PEV charging stations.
AeroVironment and PNNL share the vision that with millions of plug-in
vehicles charging at any given time, modulating the aggregate charging
rate of PEVs can help control grid frequency and support the integration
of variable renewable generation sources, such as wind and solar.
"These technologies will result in a triple-win," said Dr. Alec Brooks,
chief technology officer of AeroVironment's EES business segment.
"First, reducing the cost of integrating variable renewable generation
reduces electricity costs for all ratepayers. Second, plug-in cars can
be powered by renewable generation that might not have been possible to
add to the grid without the charging rate flexibility offered by
vehicles and this technology. Third, the reduced cost of electricity to
plug-in vehicle drivers will further improve on the cost advantage of
driving on electricity as compared to gasoline."
"Vehicle charging infrastructure is important for the market adoption of
electric vehicles and plug-in hybrid electric vehicles," said Dan Ton,
DOE's program manager of Smart Grid Research and Development. "We need
charging stations and we need them to be intelligent in order to work
with smart vehicles and smart grid infrastructure to avoid potential
strain on the grid and to provide flexible billing transactions for
energy and grid services."
Prototypes of the new AeroVironment charging system are available
immediately for beta testing. The prototypes include Bluetooth wireless
connectivity for data streaming and local control functions. Contact sales@avinc.com
