GM-Backed Envia Claims World Record Energy Density for Li-Ion Battery
Envia Systems today announced test results that verify the company's next-‐ generation rechargeable battery has achieved the highest recorded energy density of 400 Watt-‐ hours/kilogram (Wh/kg) for a rechargeable lithium-‐ion cell. When commercialized, this 400 Wh/kg battery is expected to slash the price of a 300-‐mile range electric vehicle by cutting the cost of the battery pack by more than 50 percent.
The testing of Envia's next-‐generation lithium-‐ion battery was performed by the Electrochemical Power Systems Department at the Naval Surface Warfare Center (NSWC) in Crane, Ind., under the sponsorship of ARPA-‐E. Tests at various cycling rates at NSWC confirmed that Envia's automotive battery cell demonstrated energy density between 378-‐418 Wh/kg for rates between C/3 to C/10 for a 45 Amp-‐hour (C/3) cell. Similar cells have been cycling in Envia's test labs for over 300 cycles. NSWC Crane will also test these cells to validate cycling performance
"Since the inception of Envia, our product team has worked tirelessly and logged over 25 million test channel hours to optimally develop each of the active components of the battery: Envia's proprietary Si-‐ C anode, HCMR cathode and EHV electrolyte," said Dr. Sujeet Kumar, Envia Systems co-‐founder, president & CTO. "Rather than just a proof-‐of-‐concept of energy density, I am pleased that our team was successful in actually delivering 400 Wh/kg automotive grade 45 Ah lithium-‐ion rechargeable cells."
"Envia's new battery technology represents exactly the kind of innovation and breakthroughs that ARPA-‐E is looking for from the American research and development community," said ARPA-‐E Director Arun Majumdar. "We hope that this low cost and high density battery technology enables wide spread adoption of electric vehicles across the country and around the world."
"In an industry where energy density tends to increase five percent a year, our achievement of more than doubling state-‐of-‐art energy density and lowering cost by half is a giant step towards realizing Envia's mission of mass market affordability of a 300-‐mile electric vehicle," said Envia Systems Chairman and CEO Atul Kapadia.
IBM links EV charging networks across Europe
Published December 21, 2012
A new project spearheaded by IBM could ease EV range anxiety in Europe by making it simpler for drivers to recharge their vehicles at public charging stations –- regardless of whether or not they use the same service or network at home.
Through the so-called B2B Marketplace effort, IBM is developing technology that will allow utility companies and services providers to link their networks more easily.
This will reduce the challenges associated with managing payments across different charging networks and handling international currency conversions.
The system will be transparent for EV drivers, allowing them to roam from region to region using public charging infrastructure as necessary -- regardless of what energy provider or EV infrastructure company "owns" it.
B2B Marketplace borrows from the model used to support international roaming services on mobile phones, says IBM. It would create a network of EV charging services that are compatible regionally in Europe.
The initiative is part of the Green eMotion project funded by the European Union, which aims to establish a Europe-wide EV charging network by 2015.
"This marketplace will pave the way for the electromobility mass market in Europe. It allows for open access to charging spots throughout Europe thus making the journey with an e-car simple and convenient," says Heike Barlag, an engineer with Siemens AG and Project Coordinator Green for eMotion.
IBM is one of 43 energy providers, EV manufacturers, technology companies, municipalities and research organizations involved in Green eMotion. The new marketplace uses data analytics software from the IBM SmartCloud Enterprise group along with technology and services form Enel, SAP and Siemens.

Charge your car without wires
Anuvu: Car of the Future
by Ed "Redwood" Ring / EcoWorld.com
There are many candidates for next-generation cars: high-tech
diesels, hybrids, super-engineered gasoline powered cars, electric cars,
and fuel cell cars that use reformers. But the most efficient we've
seen yet is a prototype being developed by Anuvu Inc. in downtown
Sacramento, California. It's a car that promises to require almost
no maintenance, should last
for decades, and can run 700 miles on $20 worth of electricity
(at $.10 per kilowatt hour).
Unlike most Americans, I'd rather not drive. Maybe it's because I
live in Manhattan, where the traffic is awful, the parking worse and public
transportation by far the best choice. Half the time, I don't need transportation
anyway. In the
city, it's often easier and faster to walk. That said, I do
own a car. Not a particularly exciting one. Neither new nor powerful, it
accelerates to 60 at a very old-fashioned rate, topping out
at 85 mph. The fuel economy isn't great either, but I drive so rarely,
it hardly makes a difference. Why such an uninspiring model? It's a family
hand-me-down that we got for free. There have
been three such gifts over the years, and I'm truly grateful
for all of them, but lately I've been wishing that we had the excuse (or
need) to buy a car of our own. Then, we could get one of those half gas,
half electric wonders called hybrids, or HEVS (hybrid electric vehicles).
Maybe it's just vanity. If I am what I drive, as the car companies would
have me believe, I don't want to be the hundred-year-old internal combustion
engine. I want to be the best, latest and smartest thing on wheels. Right
now, that's the hybrid -- the cleanest, most efficient, quietest, most
convenient vehicle available for the passenger market. Hybrids combine
a small gasoline engine with a battery-powered electric motor, which provides
extra power when the car accelerates or climbs
hills. The electric motor also kicks in when the car cruises
at low speeds, and in some hybrids, the car can start accelerating purely
on electric power. The engine turns off when the car comes to a stop, then
restarts automatically when the accelerator is pressed. Hybrids also capture
and convert energy from braking that would otherwise be wasted. These various
features can result in up to double the mileage of conventional
cars, as well as lower smog-forming emissions. That's not to say hybrids
are anywhere near as clean as pure electric vehicles. However, they have
one great advantage for consumers: they do not need to be plugged in. Simply
driving the car recharges the battery.
Currently, you can choose among three hybrids -- the Toyota
Prius, Honda Insight and Honda Civic Hybrid -- all excellent cars. And
the number's about to grow. Mid-sized, luxury and SUV hybrids are due out
later this year and next. As you probably know, hybrids have developed
quite a cachet among the Hollywood set -- Cameron Diaz, Meryl Streep and
NRDC board member Leonardo DiCaprio come to mind. Don't let that persuade
you that hybrids are out of your class. The cars tend to be surprisingly
reasonable, with current models averaging around $20,000. You can even
get a federal tax deduction of up to $1,500, plus sales tax waivers in
And, of course, hybrids are much cheaper to operate than
conventional cars. The calculator at fueleconomy.gov shows that the
annual fuel costs for my family would be $500-$600 lower if we drove a
hybrid, assuming we traveled 15,000 miles a year.
All I can say is thank goodness we don't. With savings like
that, I'd have no choice but to look our gift horse in the mouth. —Sheryl
Eisenberg BETTER CONVENTIONAL CARS If you're in the market
for a new car, keep in mind that even among conventional vehicles, fuel
economy and emissions vary widely. The best cars incorporate many of the
same efficient features found in hybrids, such as:
- Aerodynamic design.
- Lightweight materials, like aluminum and high-strength
- Automatic shut-off at stop lights and instant
restart when the accelerator is pressed.
- Five- and six-gear transmissions.
- Continuously variable transmissions (CVT), which
do away with gears altogether.
- Four-valve cylinders and variable valve timing.
To ensure you get an efficient model, do your homework
on the web. Use the EPA and ACEEE links I've provided
to check out your chosen car's ratings.

There she is -- the car of my
dreams. While the purple's pure
fantasy, the car is a real Toyota
Prius, Motor Trend Magazine's "2004
Car of the Year." Commenting on the
choice, editor-in-chief Kevin Smith
said, "The Prius is a capable,
comfortable, fun-to-drive car that
just happens to get spectacular fuel
economy. It also provides a
promising look at a future where
extreme fuel-efficiency, ultra-low
emissions, and exceptional
performance will happily coexist."
In other words, the Prius isn't just a
great hybrid, it's a great car.
Emissions and Fuel Economy.
The terms are confusing. Cars that
are said to be low in emissions
release fewer smog-producing gases
because of pollution control devices,
such as catalytic converters, in the
car. However, they still may emit
plenty of CO2, the primary
greenhouse gas responsible for
global warming. That's because
there's a direct relationship between
the amount of gas burned and the
amount of CO2 released -- 20
pounds per gallon. For that reason,
it's important to get a car that's not
only clean, but gets good mileage.
Driving Well. Whatever kind of car
you drive, you'll improve your
mileage and lower your emissions if
1) Avoid quick starts and gunning
2) Minimize use of the air conditioner
3) Remove unnecessary cargo that
adds weight to the car.
4) Keep your tires properly inflated.
5) Get regular tune-ups.
6) Keep your car in the garage if you
7) Plan and consolidate your trips.
At the gas pump, avoid "topping off"
