One of the factors holding back widespread acceptance of electric vehicles has been the development of battery storage. Until now, there has been nothing analogous for batteries to the computing industry’s Moore’s Law, which has seen integrated circuits become significantly more powerful, faster, and cheaper with each generation. While there have been incremental improvements in energy density — the primary drawback to battery power — a number of promising new battery technologies have not pannedout.
Now, a research team headed by John Goodenough, whose 1980 invention of a cobalt-oxide cathode made powerful lithium-ion batteries possible, has announced the development of a solid-state battery cell that not only has the potential (no pun intended) to store three times as much power as a conventional lithium-ion cell, but also replaces the cells’ liquid electrolytes with a glass compound. That would eliminate the fire and explosion hazard known to Li-ion power packs. (Read More…)
It appears apprehensions over the driving range of electric vehicles will be sticking around for a few more years.
Tesla initially said its highly anticipated Model 3 would posses a 215 mile per charge capacity in its base trim, encouraging rumors that the BEV would offer optional power packages and extended range. However, Big Daddy Musk tweeted yesterday the Model 3 is incapable of housing the larger batteries found on the Model X and S.
Tesla’s CEO also said the current 100 kWh battery will be as large as the company plans to go on its present passenger vehicles — but did mention larger units would need to be installed on the company’s semi-trailer-trucks and, again, referenced the possibility of an electric pickup truck.

Earlier this week, Samsung’s SDI battery subsidiary announced a new cell designed for use in electric vehicles that will supposedly improve maximum range and possess a cutting-edge quick charge capacity.
Exhibited for the first time at the North American International Auto Show, the battery comes hot on the heels of Tesla and Panasonic’s own ultra-dense “2170 Cell” planned for use on the Model 3.
While Samsung didn’t elaborate on a specific testing platform, it claims the new battery should permit a range of 372 miles on a single charge, with an 80 percent restoration after a 20 minutes quick charge. (Read More…)
Everyone and their 90-year-old great aunt knows that Tesla is putting all of its might into reaching a volume target of 500,000 vehicles in 2018, but more voices are now calling CEO Elon Musk’s timeline impossible.
Musk wants high-volume production to start in less than two years, but suppliers tell Reuters that the accelerated target is a pipe dream. Will delays in parts sourcing and other nitty-gritty issues throw cold water on Tesla’s plans (and customers’ Model 3 ownership dreams)? (Read More…)
The maker of all things that blow is apparently sucking up some government cash to build an electric car.
Britain’s The Guardian is reporting that Dyson is receiving a public subsidy from the British government to develop an EV, a project that will no doubt draw from the company’s depth of knowledge regarding small electric motors.
Chevrolet announced Tuesday that its new 2016 Volt would extend its all-electric range from 38 miles to 53 miles, which is a 40-percent improvement and would satisfy more than 90 percent of normal drives.
The feat itself would put the Volt on par with many all-electric commuters, whose normal range is anywhere from 60 to 90 miles. Of course, the Volt packs with it a 1.5-liter turbocharged four cylinder that bumps that range up to more than 400 miles, but that’s neither here nor there.
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 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 livingwith 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.
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…)
