Chevy Volt Fire Prompts Safety Investigation For EV Batteries
Three weeks after undergoing a crash test, a Chevy Volt caught fire. The car's battery was determined as the cause of the fire, though GM said its protocols for deactivating the battery following a crash would have prevented it. Either way, the National Highway Traffic Safety Association is now on the case. They're planning additional testing of the batteries, though they were quick to say, "Based on the available data, N.H.T.S.A. does not believe the Volt or other electric vehicles are at a greater risk of fire than gasoline-powered vehicles. In fact, all vehicles — both electric and gasoline-powered — have some risk of fire in the event of a serious crash." According to the president of an engineering firm, "If a lithium battery is pierced by steel, a chemical reaction will take place that starts raising the temperature and can result in a fire... If the piercing is small, that reaction can take days or weeks to occur."

Do you want to know why the American economy is swirling down the shitter? It's became Americans have become nancies. They have become sissies, if you will. They don't have the guts to take real risks. They don't have the guts to try something new.
Maybe this shouldn't be surprising. America often has been a backward "conservative" nation for much of its history. Aside from a few generations at the very beginning of America's modern history, the tolerance for risk has been decreasing rapidly. Without real risk you can't have real gain.
This story is a perfect example. This is clearly a very minor issue with a simple solution: if the vehicle gets into a collision, change the fucking batteries! But America as a culture will overlook this, and will overlook the immense economic and environmental benefits that these vehicles would bring, because they are TOO FUCKING SCARED to take what's a very minor risk.
This happened with an old laptop battery I had which was pierced after a fall and left in a metal trash bin. Nothing serious resulted but people need to be aware that damaged batteries are always dangerous. The fact it happened ona volt seems irrelevant. Maybe they can release a new car and call it "duravolt" (like duracell batteries except with a volt tag).
Especially in an accident. Not sure why the Volt would get singled out. There's all of six of them on the road. Hell, VWs don't even require accidents to burn up.
How long before we see a TV show or mystery novelist use an intentional puncturing of a battery to kill someone weeks later?
I give it two years, any other guesses?

And fuel fumes case an explosion if an open flame or an electrical sparc is present. What's your point?
I was always skeptical of the Chevy Volt, not because of its technology per se, but because of the "executor". In this case, engineers at Chevy.
After living in a household that owned Chevys for decades, and seeing how poor workmanship was an almost guaranteed feature in all those vehicles, the Chevy left a bad mark on my mind.
Even simple stuff like seats were poorly done. The cars over heated in the summer, and many of them would just lose power when you needed it most.
Needless to say, I do not think I will ever own one even if given to me as a gift.
* My brothers '72 Capri caught fire in the garage and nearly burned our house down.
* Windmills only kill condors left, but not right.
* Radar ground clutter is well known.
* Using heater uses energy of course. Can't blame Obama for laws of physics being inconvenient sometimes.
* I tend to agree with you on the silliness of ethanol.
Private market is no paragon of virtue. Recall AIG?, Enron? BP oil spill? Bhopal chemical leak? etc. etc.?
Sorry, but gray text on gray background is making my eyes bleed.
innovation is virtually impossible for mass-production companies to "slot in" to the "efficiency engine". they literally can't do it. there are also legal issues that need to be taken into account, such as a guaranteed 7-year-supply of parts *after* the vehicle's *last* mass-production run is finished.
The legal requirement for supplying parts can be evaded by only leasing the vehicles. Numerous mass-production businesses have done that for prototypes such as the EV1 (look over this Wikipedia list of modern electric vehicles and see the number of "lease only" vehicles, usually in the US, on the list).
If a lithium battery is pierced by steel
Are you saying we are using steel in cars again? I thought with the exception of the drivetrain, they were pretty well all plastic today.

Just wondering, why does your 3D model's bodywork look like it was shaped with a sledgehammer?

Hilariously, that's what caused the fire. The fuel tank is DRAINED after collision. Apparently people doing the test didn't drain the battery, as the manual told them to in addition to draining the fuel tank.
Hey also I was watching the vid where you wind-tunnel test the cardboard model and I had some ideas:
First I noticed you had a low-pressure area forming behind the back glass. You should consider installing a "scoop" as seen on the leading edge of the Lancia Stratos' rear window and many other rally cars:
http://www.zercustoms.com/news/images/Lancia/2011-Lancia-Stratos-8.jpg
They generate a bit of lift but reduce drag - and in many cases the lift that's killed by filling the low-pressure area behind them is less than the device itself creates, so you get net downforce.
For powertrains, I guess you know that a typical FWD ICE+transaxle isn't going to fit anywhere in that car. You could probably squeeze in a FWD transaxle with an electric motor into the front, in the back it looks like you have even less forward and vertical space so you're pretty much restricted to electric motors back there. I guess a front engine/RWD layout is out of the question due to the drivetrain inefficiency and weight. Another option you might want to consider is a sportbike engine and gearbox and either a chain-driven axle (like go-karts use - downside is the fragility and amount of maintenance required) or a custom diff setup. You could surely fit that into the front and possibly even in the back.
Next, about cooling, I assume you're going to have a '30s car style radiator grille opening in the front and some hood vents ahead of the doors and/or windscreen? Is the German electric motor you were talking about liquid-cooled by any chance?

And here they are, from the 2-hour training session for first responders to Chevy Volt accidents. It's necessary to open the trunk and cut 12V cables at two points with heavy wire cutters. The cut points are marked with yellow tape printed with a firefighter hat and wire cutters. Here is GM's official instruction sheet for this. There's also a battery disconnect switch inside the center console of the vehicle, where a big plug is turned and removed. That's the normal procedure for disconnecting power during service.
So that's the documented "protocol following the crash". That's what GM says to do, and what a first responder or a tow company would have done if they did everything right. It would have had little effect if a battery had an internal short.
The Prius, Civic, and Ford Escape each have completely different battery disconnection procedures. The first responder community is not happy about this. They want a standardized, easy to get at way to quickly disconnect the high voltage battery in an emergency.
No, you've confused the instructions for first responders with the instructions for the dealerships doing post-crash repairs.
Per a post elsewhere:
Still it's a good thing NHTSA is looking into this (while not picking solely on GM). After the Toyota unintended acceleration issue the US auto safety regulators looked bad because they appeared to have not paid attention to the early warning signs, and that ended up being bad for the regulator, the regulatee, and the consumers. Even if this turns out to be a total non-problem, it will help debunk fear-mongering against EV technology. IMHO.
Lets face it if you rode up to the regulators today on your horse and said: "I have a new idea for a product. It will be a giant metal shell on wheels. People will sit in it and move at 60km/h in opposite directions on a narrow road only a meter appart. The metal shell will become the subject of about half of your efforts to control how people use it. Best of all it runs on a highly volatile mixture of hydrocarbons."
There's no way a car could be invented today.
I live off the grid, have plenty of spare power from my PV panels, which I plan to use to keep the thing charged. I don't have to commute (retired) anyway, except to the beer/munchie store. I don't *have* to drive more than once a week or so, and one charge will get me to town and back fine.
I also have a 2011 Cruze, and it's easy to see why they are the #1 selling car these days - the thing rocks, and I love it. Granted GM (and other american companies) turned out shit for a few years. I'd just say that it's not universally true now, though I'd not get a Ford (software by MS, scary) or a Chrysler, who still use hot glue to hold their cars together, cheap crap (except for the price).. Bob Lutz really turned GM around. For many years I just bought GM commuter cars used (and real cheap due to people thinking they must be worn out after 100k), with 100k miles on them - no maintenance past changing oil had been done, and I drove them another 20k miles the same way, till I got bored and got another GM - no issues whatsoever - the bashing is just out of place, you euro-trash jerks. Go back to worshiping apple or something, and get off my lawn. GM is BACK.
Why guess when you can know? Measure!
That arguement falls down for two reasons.
a) if something like this didn't exist our world would likely be as it was during the time it was invented, and we would likely have thought "What is the point of that? I have a horse!"
b) You're ignoring my point that we have become an insanely litigious society. It's not a necessity that will or won't allow us to move forward, its the fear of getting sued the first time something like this causes a death.
The only thing that saves the car is entrenchment. Take a look at typical industry today while you're at it. Why is it today we say nuclear power is too expensive whereas in the 60s it was seen as a way to finally make cheap power? Our society has changed for the risk averse where these days people are much more concerned about building an intellectual property portfolio than build equipment.
