GM Awards Advanced Development Battery Contracts For Chevrolet Volt E-Flex System

Yeah, after a brief hiatus, im back. Please note that these are lithium ion batteries, not smoke and mirror batteries. Thank you.

GM Chairman Rick Wagoner announced that the company has awarded two advanced development contracts for battery systems to be used on the GM E-Flex platform. For those who have missed the news for the last six months, E-Flex is the electric propulsion system used in the Chevy Volt concept. GM is moving ahead with production engineering including building proper prototypes so they need real batteries.

Continental Automotive Systems and Compact Power Inc. will be supplying the integrated lithium ion battery systems to GM using cells from A123 Systems and LG Chem respectively. The press release is after the jump.

Contracts Mark Important Step in Developing Range-Extender and Fuel Cell E-Flex Variants

WILMINGTON, Del. – General Motors has awarded two contracts for advanced development of lithium-ion batteries for its electric drive "E-Flex System," it was announced today at GM's annual shareholder meeting.

GM selected two companies out of the 13 technical proposals it considered to provide advanced lithium batteries for both range-extender electric and fuel cell variants of the E-Flex architecture. The E-Flex electric vehicle architecture underpins the Chevy Volt concept car shown earlier this year and is being developed as part of GM's strategy to diversify transportation away from petroleum.

One contract will go to lithium-ion battery supplier Compact Power, Inc., based in Troy, Mich. CPI is a subsidiary of Korean battery manufacturer LG Chem. A second contract has been awarded to Frankfurt, Germany-based Continental Automotive Systems, a division of Continental A.G., a tier one automotive supplier that will develop lithium-ion battery packs. GM continues to assess other solutions to quickly bring lithium-ion batteries to production.

"The signing of these battery development contracts is an important next step on the path to bring the Volt closer to reality," said GM Chairman and CEO, Rick Wagoner. "Given the huge potential that the Volt and its E-Flex system offers to lower oil consumption, lower oil imports, and reduce carbon emissions, this is a top priority program for GM."

The E-Flex System was first shown as the plug-in battery electric propulsion system for the Chevrolet Volt concept vehicle at the North American International Auto Show in January. A plug-in fuel cell variant of the E-Flex system was shown at the Shanghai Auto Show in April. The "E" stands for electric drive; the "Flex" represents the architecture's adaptability to be configured in several vehicle packages operating on various sources of electricity.

These suppliers demonstrated solutions that best met the specific energy, power, mass and durability requirements for the battery in the E-Flex range-extender variant. The battery for the fuel-cell variant requires half the energy and power, but must be integrated and connected to the vehicle in a similar way.

"This technology is developing rapidly," said Denise Gray, GM director of hybrid energy storage devices. "These contracts are an opportunity to deeply understand the differing battery technologies before making a production decision."

The signing of these advanced development battery contracts for the E-Flex system is the latest proof point in GM's effort to transform the industry by diversifying automotive transportation away from petroleum with a range of propulsion alternatives. These include:

A diverse lineup of hybrid models now in production, including:

- The GM diesel hybrid electric system for large city buses
- The Saturn Vue and Saturn Aura Green Line hybrid models
- Coming this fall, models of the Chevrolet Tahoe and GMC Yukon SUVs that feature the world's first use of the 2-Mode hybrid system, providing a more than 25-percent improvement in fuel economy to what is already the industry's most fuel- efficient full-size SUVs.
- Due next year is a front-wheel-drive 2-Mode hybrid Saturn Vue Green Line, with plans to make a plug-in version of the Vue that has the potential to achieve double the fuel efficiency of any current GM SUV.
- In May, GM completed the longest fuel cell-vehicle demonstration drive in history with the 300-mile drive of the Chevrolet Sequel. It is also a leading producer of E-85 capable bio-fuel vehicles, with more than two million on the road.
- GM is also the first automotive member to join the U.S. Climate Action Partnership (USCAP), a group of global companies and non-governmental organizations formed to support an economy-wide, market-driven approach to reducing carbon emissions.

Yeah, if you cant tell, I also try to keep things positive =).

Lutz's treatment of issues like fuel economy and emissions is what really keeps me from loving the guy. From the standpoint of bringing GM some more exciting cars (think Cavalier vs. Cobalt SS), and improving interiors (Aura, 09 Malibu), and kicking out the bean counters he has done excellent. But when it comes to MPG and emissions, he just dosent seem to give a crap, and that really dissapoints me.

It is as though GM treats its smallest vehicles as though they should be the least expensive of their portfolio, and not the most fuel efficent. What is amazing is to watch the MPG trends from GM's very 'efficent for its size' Impala downward through the Malibu, Cobalth and to the Aveo. The Malibu and Cobalt are almost identical in MPG, that would be like the Corolla getting the same MPG as the Camry. And while this does to a very minor extent speak well of the Malibu, it speaks very poorly of the Cobalt.

I once stated (to much flaming on the GM website) that having the most economical fullsize SUV, while admirable, is like being the fast marathoner over 300lbs. I.E., good for you, but you still suck.

Anyways, I am very confident that GM has finally woken (waken?) up, and will continue to do very well. I hope that they realize this new way of doing business is the new 'norm' for them, and not just a temporary rush to get caught up again.

While I am very confident that the Volt will see production, I do have to admit that if gas prices tank (to the tune of 1.50 a gallon), it has a strong chance of getting axed. GM seems to be doing this for MPG reasons, and the eco benifit is just a side bonus. But, I doubt we'll see 1.50 gas anytime soon, so I remain confident.

BTW.. just want to say.. I enjoy my convos/debates on this forum ALOT more than on my GM forum.

Cheers.
