Announcements of businesses leaving regulation-happy and costly California or declining to do business in California are as common here in the Golden State as seeing a Prius blocking the left lane on the 405. This move is a bit of a surprise as California-based Tesla Motors said this morning that they have eliminated the state as a possible site for their $5-billion dollar battery factory, meaning only Texas, New Mexico, Arizona and Nevada remain in the running.

The hagiographic article by Bloomberg/Business Week on outgoing General Motors CEO Dan Akerson did exactly what Selim Bingol and the other PR honchos in the RenCen towers wanted it to do. With other news agencies and blogs amplifying the puffery and pulling quotes, the article got GM and Akerson a lot of good press. One of the quotes that got pulled the most was Akerson’s reference to a “moon shot” project giving GM’s next generation extended range electric vehicle a 200 mile range on battery power, based on breakthroughs in battery technology. It may be more of a moon shot than Akerson let on, since GM has cancelled its contract with that battery’s likely supplier, accusing it of “material misrepresentation”. (Read More…)

That CFRP cowl panel is really storing electricity.

BMW is using carbon fiber composite unibodies for the electric i3 and i8 models to reduce their weight, thereby increasing their range. Now, Volvo is using carbon fiber in a novel way for EVs. Using carbon fiber it has developed a composite material that acts as a capacitor, storing electrical energy, so theoretically body panels and structural components could act as battery equivalents. Unlike conventional batteries, which add weight to a vehicle, the carbon fiber capacitive body panels wouldn’t just power the vehicles but also reduce weight.

LG-Chem

Only weeks after starting up long-delayed production of lithium-ion batteries for the Chevy Volt at their new factory in Holland, Michigan, LG Chem has announced that they are stopping production for up to six weeks because a compound used in that production apparently had not been registered for use in manufacturing with the U.S. Environmental Protection Agency. While no shutdown order was issued by the EPA, the agency recently issued a subpoena to LG Chem, demanding a list of chemicals used at the Holland facility.

LG Chem spokesman Jeremy Hagemeyer said in an email to news agencies, “We discovered the possibility that this material may not be properly registered and made the decision to pause our production until we have that question resolved. We are currently reviewing the registration status and will work with the EPA to resolve the issue quickly. In the meanwhile, we are delaying production activities for approximately 6 weeks until we have confirmed the registration status or otherwise obtain approval from EPA.” (Read More…)

TTAC has borrowed EVs in the past. Nissan even let us snag a Leaf for a week. Since then, I’ve driven every EV on the market except the Model S. (Not for a lack of half-trying, I call Tesla HQ regularly, but am too lazy to visit a Tesla dealer.) Every time I’ve had an EV, the conversation is more about living with the EV than the car itself. This time we’re doing something different. When the review of the spunky little orange Fiat 500e (I’ve decided to name her “Zippy Zappy”) hits in a few weeks, it will be 100% about the car and 0% about EV trials and tribulations. That divorced conversation is happening this week in daily installments.

South Korean LG Chem will finally begin commercial battery production at its Holland , Michigan, in July, Reuters says.  The batteries will initially help power GM’s Volt.

Three years ago, at a groundbreaking ceremony for an LG Chem Battery plant in Holland, Michigan, President Obama promised that this and other pants will be “a boost to the economy in the entire region.” The plant made headlines for doing nothing. (Read More…)

Researchers are quickly getting disenchanted by the high price of lithium-ion batteries, paired with a growing number of high-profile incidents involving smoke and fire, Reuters says in an in-depth analysis. Some are looking way beyond Lithium-Ion. Some go back to technology that is older than the car: Lead-Acid. (Read More…)

Energy density isn’t the only reason why battery-powered cars have never caught on. As was highlighted in Tesla’s somewhat less than successful media road trip, the amount of time it takes to fill batteries with electrons can be as significant a factor in the practicality of EVs as the amount of electrons those batteries can hold.

The drama circling around the New York Times test of the Tesla Model S doesn’t surprise me one bit. Why? Because I understand, perhaps at a deeper level than most of the motoring press, how batteries work. Perhaps that has to do with growing up in a family of engineers and scientists, but battery technology has always interested me. So when people from Phoenix came to me crying in their soup about their LEAFs in the heat and friends started wagging fingers at Tesla and the New York Times, I figured it was time for a battery reality check.

U.S. Senators long have warned of an exodus of American know-how to China. Last year, Michigan Senators Debbie Stabenow and Carl Levin complained to United States Trade Representative Ron Kirk about another attempt by China ”to illegally gain an unfair advantage over the U.S. automobile industry that will cost our country jobs. The United States must respond strongly to stand up for American businesses and working families.”

A year later, the exodus is in full swing, and it starts to hurt. This time, it pains automakers to see how Chinese companies are getting their hands on taxpayer-funded secrets. (Read More…)
