“To my knowledge, at this point, ExxonMobil has no interest in putting charging stations at retailer locations,” said Pat Brant, Chief Polymer Scientist with ExxonMobil Chemical Company. I just had to ascertain if ExxonMobil was really in the car business after they announced their partnership in launching the Maya 300 and it appears that the answer is no. However, ExxonMobil Chemical Company, a subsidiary of ExxonMobil that was built from scratch 18 years ago, is is in the business of developing technologies to improve technologies with battery applications.

So here is how the partnership works. ExxonMobil Chemical Company developed the pioneering lithium ion battery separation technology. They then partnered with Electrovaya, to integrate the technology into their batteries and then manufacture the batteries. The batteries are then given to Electrovaya subsidiary Maya, who then manufactures the Maya 300. So there, ExxonMobil is not in the car business.

Speaking of the car business, one of the burning questions is how is the Maya 300 different than other electric vehicles. There are three main reasons.

1. The Maya 300 is powered by a Lithium-Ion SuperPolymer® battery (made by Electrovaya). The lithium-ion polymer technology platform enables lithium to be moved faster and more efficiently, allowing more energy to be stored in a smaller space. Most other hybrid and electric vehicles are using nickel-metal-hybrid batteries that take up more space and are heavier.
2. Smaller battery. Smaller space. A conventional lead acid battery pack on average takes over five times the space and weight of the Electrovaya battery pack.
3. Style. The Maya 300 looks like a traditional four-door car with a hatchback. On the road, aesthetically speaking, you’d be hard pressed to tell it was an electric vehicle.

Editor’s Note: This is a guest contribution by Richard Lowenthal, CEO of electric vehicle ChargePoint manufacturer Coulomb Technologies. See his last post here: Henrik Fisker Debuts Karma Plug-in Hybrid in San Jose. This is part of our ongoing series on EV Charging Infrastructure, which was initiated by Mayors Gavin Newsom and Sam Adams.

This week, Coulomb Technologies announced that Walnut Creek, California has become the third Bay Area city (along with San Jose and San Francisco) to deploy Coulomb’s ChargePoint™ Networked Charging Stations for electric vehicles.

Coulomb’s charging stations were officially welcomed in a ribbon cutting ceremony in downtown Walnut Creek.  We were joined by the city managers of Walnut Creek and Orinda as well as Walnut Creek city officials.  As many California readers know, Walnut Creek is considered one of the top destinations in the Bay Area, known for its outdoor festivals, performing arts scene and superb shopping and dining.  EV owners across the Bay Area now have a premier destination where they can recharge while enjoying downtown Walnut Creek.

When it comes to electric vehicles, critics have referred time and again to the fact that the death and replacement of batteries nullifies any savings made at the pump. With a battery’s limited lifespan, and battery prices still high, drivers may not be saving much. However, recent tests by battery provider Southern California Edison (SCE) show 

Over the past two and a half years, SCE has been testing a lithium-ion battery sub-pack. And the results are incredible.  The lithium-ion battery has displayed remarkable longevity, surviving 180, 000 miles with no significant deterioration. With the average family vehicle traveling less than 15,000 miles per year, this test holds great significance. This dramatic increase in the life expectancy of an EV battery pulls the cost equation more convincingly on the EV’s side.

The BMW mini coups took the U.S. by storm in part, due to its great gas mileage. Well, now BMW has launched the MINI E, an all electric, zero emissions car. Peter Trepp of Pacific Palisades has become the first consumer in the country to drive the car. He will have it for one year as part of a one-year field study. Additional consumers in New York, LA and New Jersey will also be taking ownership of their MINI E by the end of June.

I’m only slightly miffed that I wasn’t selected to test-drive the car for a year but I’ll get over it. In the meantime, the rest of us can follow Peter through his blog “Plugged-In With Peter’s MINI E,” which can be viewed at http://www.petersminie.blogspot.com/. Yes, his blog is a marketing tool but I can’t resist and I will be following him. Maybe we’ll even be able to get him to write a special piece for us at Gas 2.0. Read the rest of this entry »

Researchers at the Massachusetts Institute of Technology (MIT) have developed battery cells capable of charging in under a minute, an astonishing 100 times faster than a regular rechargable battery.

The breakthrough could revolutionize electric car battery technology and pave the way for ultra-fast charging electric vehicles in as little as two years.

The discovery came when MIT researchers Byoungwoo Kang and Gerbrand Ceder found out how to get a common lithium compound to release and take up lithium ions in a matter of seconds. According to Ceder, the compound, known as lithium iron phosphate (LiFePO4), has a crystal structure that creates “perfectly sized tunnels for lithium to move through,” allowing the team to reach “ridiculously fast charging rates.”

Nissan and the Portuguese Government have signed an agreement to study whether or not to invest €300 to €400 million euros in an electric car battery plant in Portugal.

As I’ve reported before, although Nissan was a little late to the electric car party, they have recently been investing heavily in electrification including several major deals with local and state governments around the US and the world to roll out an electric car charging infrastructure.

Since the late 1800s, the primary impediment to the adoption of electric vehicles has been battery technology. And while the technology has advanced by leaps and bounds in the last decade or two (compare your cell phone with one from the early 90s), with a threefold improvement in energy density and more than an order of magnitude improvement in power density, it still lags behind gasoline.

Some have argued that current technology is sufficient — that the ability to drive 1 1/2 hours to 3 hours nonstop is good enough for the overwhelming majority of trips, and that paired with a range extender, rapid chargers, or battery swapping, you have a viable means of replacing the gasoline car. However, there still is a great deal of pressure to get electric vehicle range up to that of gasoline.

Enter Yi Cui. Again.

The BMW Group is about to become the first manufacturer of premium automobiles to deploy a fleet of nearly 500 all electric vehicles for private use in daily traffic. Powered by a 150 kW (204 hp) electric motor and fed by a high-performance rechargeable lithium-ion battery, the vehicle will be nearly silent and emissions free.

The Mini E will have a range of about 150 miles and will initially be offered to select private and corporate customers in California, New York and New Jersey, but will first be given its world premiere at the LA Auto Show on November 19th and 20th, 2008.

As for its speed, BMW claims that it will offer acceleration to 62 mph in 8.5 seconds with a top speed that is electronically limited to 95 mph.

Editor’s Note: This post is a response to Anthony Cefali’s recent article “Where We’re Going We Won’t Even Need Lithium: A Neurotic Look at Our Energy Future.”

Recently, fellow Gas 2.0 author Anthony Cefali wrote an excellent post questioning the sustainability of lithium-ion batteries into the future due to concerns over the supply of lithium.

In this world, it’s easy to argue that one can never be too neurotic about our future, as our species has repeatedly shown a lack of foresight into the consequences of its actions. However, in this case, I must argue against his views on lithium’s sustainability. Lithium-ion batteries will only be superceded by superior technology, not by lithium shortage.
