Meet the World's First 150 MPG Plug-In Prius

By EV World
March 07, 2005

PHOTO CAPTION: Based on the pioneering work of UC Davis professor Andy
Frank, the marketing efforts of Felix Kramer and the engineering efforts of
EPRI, grid-chargeable hybrids like the one developed by Energy CS are
beginning to get serious attention from both the media and policy makers,
if not car companies. This stock 2004 Toyota Prius is powered by 9kW
lithium ion batteries developed by Valence. Greg Hanssen is on the left.
Peter Nortman is standing on the right. Kneeling is Valence engineering
representative, Mark Kohler. This car is now on its way to Monaco for EVS 21.

From-the-field interview with Energy CS principals Greg Hanssen and Peter
Nortman on their 150 mpg plug-in Toyota Prius

Okay... so as to not confuse you any more than you might already be, Energy
CS' plug-in Toyota Prius gets between 120-180 miles per gallon equivalent
for the first 50-60 miles of the day. After that, it drops back to the
standard Prius 50 mpg average.

So, how's that work, you ask?

Simple. For the first 50-60 miles, it runs mainly on electricity stored in
its brand new, 9kWh Valence U-Charge Lithium-ion Saphion battery pack. The
gasoline engine runs so seldom that you would effectively get the
equivalent of up to 120 mpg under normal driving conditions using a
combination of EV mode driving and electrically assisted gasoline engine
driving. With less aggressive driving (and thus lighter use of the gasoline
engine) gasoline consumption can be as low as 180mpg.

Of course, you can drive as far as you like in the normal Prius
gasoline-electric hybrid mode, but then you drop back to the still very
respectable 50 mpg.

In practical terms, since most people drive only about 25-40 miles a day,
you'd use more electric power than the normal Prius. In effect, your energy
would come from the power grid and you'd pay for your "fuel" through your
electric power bill instead of to the oil company.

Starting to get the picture? See why environmentalists, electric utilities
and all those national security wonks in Washington, D.C. are so excited
about the plug-in hybrid concept? It's an idea whose time has come, though,
as you might expect, carmakers are less than enthusiastic about it, arguing
that its impractical and too expensive.

What can't be argued is that the technology now exists to make it happen
and there are small research programs cropping up all over America. I
happen to luck out while in Los Angeles in the end of February and got to
see one of those projects just before the car was shipped to Europe for EVS
21, this one created by a small engineering shop located in the foothills,
in the heart of Monrovia. That firm is Energy CS, headed by my old friend
Greg Hanssen and his partner Peter Nortman. They've taken a stock 2004
Toyota Prius gasoline-electric hybrid, removed the 1.3kWh NiMH battery
pack, installed a 9kWh Valence U-Charge pack powered by the Austin, Texas
company's Saphion lithium-ion battery chemistry.

Editor's note: We recorded an extensive interview with Valence executives
the week before travelling to LA. That interview will air in the near future.

In this "from-the-field" interview, Greg Hanssen and his partner Peter
Nortman explain the origin of the project, whose spiritual 'godfather' is
Felix Kramer with CalCars. Hanssen, who is, to my knowledge at least, the
only person to drive a GM EV1 electric car across America twice (recharging
at my house on one occasion), does most of the talking in this MP3 audio
'podcast'. Hanssen had just driven the car back from the California EPA
office where it had been undergoing preliminary testing most of the day.
Within hours, the Energy CS crew would be preparing the car for a
cross-country trip to Jacksonville, Florida and a 'date' with a freighter
bound for France.

To listen to the interview, use the Flash-based MP3 player just below the
picture or download the file to your computer hard drive for later playback
on your favorite MP3 device.

You'll be hearing much more about plug-in hybrids the higher the price of
gasoline goes, so stay plugged into EV World.

babys."...

price be? FYI...
08/Mar/2005 Felix Kramer: Want a PRIUS+ someday? We've started a
Newsletter to keep people up-to-date on the progress of PRIUS+
(http://www.priusplus.org), CalCars (http://www.calcars.org), and what are
called gas-optional or plug-in hybrids (PHEVs) in general. To subscribe, go
to http://http://groups.yahoo.com/group/calcars-news/ . Though we don't yet
have any information about when conversion options will be available to
individuals, when they do (from for-profit companies such as EnergyCS, not
directly from The California Cars Initiative, which is nonprofit), we
expect they will be installed kits, with some kind of warranty for the
components, but we do expect the conversion will void some or part of your
Toyota warranty. We expect to be able to convert 2004-2005 Prius (not early
generations). We think conversions will be possible for Toyota Highhlander
and Lexus RX-400 hybrids, and probably for Ford Escape. Because of their
different architecture, we are currently devoting no attention to
conversions of Honda Insight, Civic or Accord hybrids. "
