125 MPG+ Prius Prototype Unveiled

We've already heard that the 2008 Toyota Prius might be capable of over 80 miles per gallon, but it looks like Toyota isn't stopping there. Lithium Technology Corporation has just created a prototype plug-in Prius that demonstrably gets 125+ miles per gallon. The car uses a new kind of large-scale lithium ion battery that uses lithium iron phosphate as the cathode (wikipedia).

These batteries are well suited for cars. First, they don't explode when punctured and canada viagra second, they have a very high discharge current. The Prius' battery stores 7 kWh of electricity in 63 Li-ion cells, and the vehicle relies exclusively on the batteries for the first 60 miles of travel. The prototype is, of course, a plug-in, so the i use it order levitra online canada mileage-boosting energy comes from the electric grid. And, no, grid energy isn't emissions free, but it's a heck of a lot more efficient than internal combustion.

This is a surprising leap from Lithium Technology Corporation. I've been expecting more news about Lithium Iron Phosphate batteries for a while, but to hear that they've boosted the mileage of a prototype vehicle so substantially is levitra costs very exciting. Maybe Toyota will actually have something ready in 2010 to rival GMs ultra-efficient plug-in hybrid Volt.

Full press release after the jump.

PLYMOUTH MEETING, PA, May 14, 2007
The battery power solution for advanced automotives has arrived. Lithium Technology Corporation ("LTC") (OTC: LTHU) announced today its new product line of lithium iron phosphate (LiFePO4) cells, the largest cells of http://www.umlauf.de/generic-levitra-sale their kind in the world. This is the answer the automotive industry has been searching for.

"The technology we can offer the generic cialis automotive industry today is unmatched by any other battery power solution on www.aldentheatre.org the market," commented Dr. Klaus Brandt, executive vice president of LTC and managing director of LTC subsidiary GAIA Akkumulatorenwerke (GAIA). "Others have been estimating up to tramadol cheap no prescription a year to deliver the technology we are proud to make available today. We have proven the superiority of our technology in the past, and with the iron phosphate product we have raised the bar even further."

LTC, a global provider of large lithium-ion rechargeable power solutions has focused solely on the development and production of large format lithium-ion batteries for more than twenty years. Unlike others, our advanced cells use LiFePO4 licensed technology, developed by Prof. John Goodenough with the University of Texas and supplied by Phostech; this chemistry coupled with the company's innovative end-to-end manufacturing processes and proprietary design, packaging and assembly techniques, allow LTC to provide high performance cells unmatched by any other product.

"Batteries made of good choice canadian healthcare LTC's cells can provide 3000 charging cycles, which would be able to do 150,000 miles to 80% capacity for a 100 km or 60 mile all electric range plug in hybrid, which no other technology can claim," said Dr. Andrew Frank, Professor, Mechanical and Aeronautical Engineering at the University of California, Davis . "The new cells from LTC provide improved safety with the iron phosphate chemistry while delivering the impeccable performance they are known for, which is what the uk cialis auto makers have been in search of; this is a Company that is seriously committed to making hybrid, plug-in hybrid and cialis internet electric vehicles an affordable reality for the consumer."

LTC's large format technology allows for the development of safer battery systems with a significantly lower number of cells. The weight of the battery is decreased while performance and safety monitoring capabilities are increased. The battery management system (BMS) is more precise monitoring fewer cells, keeping them in balance for best performance and preventing damage to the battery due to lowest price cheap discount cialis professional over voltage, under voltage, over temperature and short circuit.

The Company's new product line offers cells ranging from 6 Ah to 35 Ah. Further statistics will be discussed at an expo of LTC's breadth of power solution on May 23rd in New York City.

It's funny, this makes me think that Toyota's plan all along was to market an electric car with a backup gasoline system.

Certainly you can skew your mix of gas/diesel/electric components in any direction to make the car more efficient or cheaper. AS IT is, I admire the prius, but I feel that it has been skewed in the direction of cialis online without prescription making it more efficient on city streets for a premium cost.

Since I drive mostly highway, it's not the best choice for me, when you figure car cost in the equation.

And, no, grid energy isn't emissions free, but it's a heck of a lot more efficient than internal combustion.

Mile for mile, a vehicle that uses 250 Wh/mile and one that gets 55 mpg put out the same amount of CO2. The electric vehicle puts out 12 times the cialis kanada NOx. Hard to see how that could be considered more efficient from an environmental perspective.

I'm not sure where that data's coming from, but I can't imagine why a pure electric vehicle would have greater NOx emissions than a ICE vehicle. A hybrid... maybe... because of the starts and stops, but when running in pure EV mode, this car would have next to no NOx emissions, because power plants capture almost 100% of their NOx emissions.

Let me know if I'm overlooking something here.

Here:
http://www.eia.doe.gov/cneaf/electricity/epa/epat5p1.html
http://www.eia.doe.gov/cneaf/electricity/epa/epat1p1.html

Net generation = 4,054,688,000 MWh
CO2 emissions = 2,513,609,000 metric tons
NOx emission = 3,961,000 metric tons

The Prius is rated at 55 mpg as-is, and 250 Wh/mile in all-electric mode. The CO2 emissions coefficient of gasoline is www.chopperssportsgrill.com 19.564 pounds per gallon.

The Prius meets two emissions standards - the EPA's Bin3 and PZEV for California, New York, Vermont, Massachusetts, and Maine. The NOx limit for the former is 0.03 g/mile; for the latter it's 0.02 g/mile.

If you crunch all those numbers, and you assume the "dirtier" Prius numbers, NOx intensity for electric is 8.14 times higher (0.244 v. 0.03 g/mile), and carbon intensity is 1.40 lbs lower every 100 miles (34.17 v. 35.57).

You can tweak the model however you like to get better carbon intensity numbers from a theoretical electric vehicle (by lowering the Wh/mile assumption and/or using Prius real-world numbers instead of EPA ratings, which would drop it to very good site viagra canada prescription around 47 mpg).

NOx is the main difference. Even the worst light vehicle emissions category (Binsmilies/cool.gif has NOx capped at 0.20 g/mile. An electric vehicle would need to get about 205 Wh/mile to reach that threshhold. Of course, these are national and not state, utility-specific, or individual figures. If one sources from carbon-neutral electricity, clearly the numbers would be different. But pulling from an average outlet, the numbers are as I mentioned.

That sunglass smiley guy shouldn't be there. I was trying to write Bin Eight and it put out a smiley instead. :-

About 1/3 of human NOx emissions come from power plants. Here's EDF's one-pager on the impacts of NOx:

It's the old "smog in the Grand Canyon" problem.

There's no doubt in my mind that the prius does better on the highway.

I get 55mpg highway. and 43-48 city.
