Elon Musk Pledges To End "Range Anxiety" For Tesla Model S
An anonymous reader writes: Elon Musk has used his Twitter account to announce a press conference on Thursday which he claims will end "range anxiety" for Tesla's Model S sedan. Whatever change they're making will be implemented through an over-the-air software update to the cars, affecting the entire fleet. Range anxiety is the term for a fear that your vehicle won't have enough fuel/charge to reach its destination. It's a common reason for people to avoid buying electric cars, given the much smaller infrastructure build-out compared to gas stations. If Tesla is improving the Model S's range through a software update, then it likely involves optimizations to the battery and to the ways in which power is used. Tesla has also talked about developing a feature called "torque sleep," which puts one of the drive units to sleep while not needed. They say it can wake up and begin delivering torque again "so fast that the driver can't perceive it."
.. range. For example, more charging stations and/or a better locator (perhaps with a partnership with a nationwide chain of stores or two), better range calculation, a service to have charging trucks come out to you to you should you run out of charge (maybe even heading to the point where you would run out of charge before it even happens so that there's no wait), or all sorts of other possibilities. There's no guarantee that it actually means more range.
Of course, it could mean that.

In order to stop drivers from micromanaging their ranges, is just to let a user know how likely is he to run out of juice, right off the bat when he starts his journey. A simple voice request from the car speech synthesizer, asking for a city, a street, or something not very specific which can be used for broad calculations, and then let the user know: "You might have not enough battery to go/come back home"/"You can make a round trip 8 times to that destination"/"You might run out of juice but there's a supercharger nearby, would you like me to reserve a spot for you at hh:mm AM/PM?"
an over-the-air software update [...] affecting the entire fleet
Yeah. That worked really well for the twelve colonies in Battlestar Galactica.

It said over-the-air so it would have to be a flying drone, not a pickup truck.

That says nothing about extending range. It talks about ending range anxiety. Which could be, for isntance, adjusting the sat nav so it calculates how much further you can drive before you go out of range of the nearest charging station.
First of all, "Range Anxiety" is a registered trademark of General Motors. I hope Elon doesn't get in trouble for using it without GM's permission!
Most people who actually own electric cars experience very little range anxiety. Far more common is "range anxiety anxiety": the fear that if you got an electric car, you might experience range anxiety.
Also prevalent among car makers is "range anxiety anxiety anxiety": the fear that, if you made an electric car, range anxiety anxiety might prevent people from buying it.
Remember folks, we have nothing to fear but. . . fear itself!
Isn't "torque sleep" a manoeuvre for stealing the covers?

Or simply using the saved energy from the software update to zap any range-anxious driver.
Whilst what you say is true there's the refilling time to take into account.
A full tank of liquid fuel takes minutes to pour in.
A full 'tank' of electricity takes hours.
Not to mention that a full tank of liquid fuel gets you about 700 miles of travel whereas a full battery only ~350

Jeremy Clarkson from the BBC's top gear has done everything in his power, for example, to cast a very negative light on even the most powerful hybrid and electric vehicles.
Really? Did you see the BMW i8 Hybrid piece a few weeks ago? The one where he chooses the hybrid over the traditionally engined car at the end of the segment? The one where he likes the car for what it is?
Stop with the bullshit that Clarkson hates hybrids or electric cars - he hates shit cars, so shit cars get hated on by him and the Top Gear team.
Perhaps Tesla will now offer discounted scrips for Xanax, to help combat that range anxiety.
Sure, you might still get stranded, but at least you won't be overly stressed about it.
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
Cars were seen as a non-polluting alternative to horses and an answer to grid lock; as well as safer since getting run over by a horse was a not uncommon occurrence.
This. People dont realize how much pollution/problems/rangers exist with horses because 99.999% of people never use them. It's just like people and diseases vaccinations have nearly wiped out.
Further with all the care horses require, modern feed, medical care, large open spaces, they actually do have a carbon cost. Due to the insane footprint of creating, transporting, and preparing food the human CO2 footprint is pretty large - so big that jogging/running is approximately the same CO2 output as driving a hybrid. The meat you almost need to eat if you excercise a lot is the most to blame.
Its *very* unusual for a full tank to get you 700 miles of travel, even at optimum fuel efficiency for the particular vehicle.
In fact, tanks are typically sized such that the vehicle in question will get in the neighborhood of 400-500mi to a tank.
Small, fuel efficient vehicles tend to have ~9 gallon tanks, this would require nearly 80mpg to reach 700 miles.
Medium-sized vehicles tend toward ~14 gallons, and would require 50mpg to reach 700 miles.
It's incredibly rare that a vehicle large enough to be paired with a 20 gallon tank would also be efficient enough to get the 35mi/gal it would take to reach 700 miles on a single tank. Exceptions come in the form of vehicles designed around long-haul transit (such as semis), built with over-sized fuel tanks.
Please tell me, where can I charge my Tesla S in 10 minutes or less along the corridor from Atlanta to New York, because I am certainly not going to make it from Atlanta to New York without charging.
This is not range anxiety, this is practical realism.
No, it's making up special cases to prove your point.
There are places out west that a proper petro fueled vehicle owner will suffer the same anxiety.
Hell, once on a Sunday trip in Pennsylvania on my motorcycle the one gas station along my remote route where I planned to refuel my motorcycle had closed. Want to talk about range anxiety?
Three points 1. Range anxiety is most definitely not confined to the Spawn of Satan Tesla. I have relatives who start sweating at 3/4 a tank of proper gasoline fuel.
2. Making up special cases is silly, like looking down on people who drive car, because you want to haul stuff, therefore why would anyone want to get a car rather than a pickup truck? All vehicles have their purposes, and maybe not everyone needs to go from Atlanta to New York with only 10 minutes to spare. You need to take a gas guzzler across the western desert some time.
3. Don't want a Tesla? No problem - don't buy one. Just because you have to have a vehicle that has to meet certain specifications doesn't mean that everyone has to. Your major issue is infrastructure, which is easily addressed over time. As the infrastructure improves, we'll see the recharge issue start to go away. Don't forget that at one time, horses had a better refueling infrastructure than petrofueled vehicles. Of course, at that point you would probably be decrying those gasoline powered vehhicles you defend so much today.

Yes, but there are a relative few number of fossil-fuel-burning power plants compared to fossil-fuel-burning automobiles, and once the electric car is built, it can be charged from electricity produced from any power plant, not simply a fossil-fuel plant. That means that the fossil-fuel plants can be replaced over time as they reach end-of-life or when they no longer meet emissions standards.
Do not look into laser with remaining eye.
Yeah, but Elon Musk doesn't make big claims like this, and intentionally generate hype, without having something genuinely interesting up his sleeve.
Base load coal plants, even including all the losses, are still more efficient than burning gasoline in a car. And obviously, electricity has many sources, so with very little impact to the overall energy infrastructure, you can replace a coal plant by nuclear or wind.
for range anxiety? VW Passat TDI. 690 miles before you have to hunt up a diesel pump.
Are you referring to the Tessum Hill Marshall study? That was discussing particulates and ozone, not CO2. Burning coal for electricity is a terrible idea, but as electric vehicles are not tied to a particular power source, they won't force us to use fossil fuels for generations.
But that doesn't mean that electric cars pollute more, it means that the U.S.A. has crappy means of generating electricity.

I don't think that article is accurate. It does not take into account the well to wheel efficiency. Hell, I can drive 30 miles using the energy required just to refine a gallon of gasoline.
