Tesla's Having Issues Charging In the Cold
cartechboy writes "It's winter, and apparently meteorologists have just discovered the term Polar Vortex, as that seems to be the only thing they can talk about these days. But seriously, it's cold, and apparently the darling child of the automotive industry, the new Tesla Model S electric car, is having issues charging in the cold weather. It's being reported that the charging cables that come with the car are unable to provide a charge when the temperature dips below zero. As you can imagine, this is an issue in a country like Norway where the Model S is one of the most popular cars. In fact, it seems this issue has already left one Model S owner stranded with a dead battery nearly 100 miles from the nearest charging station. Other owners are reporting issues charging. Tesla's European sales chief Peter Bardenfleth-Hansen apologized for he inconvenience owners are facing, and said it's 'trying hard to resolve' the issue. Apparently the issues are simply down to the differences in the Norwegian network as Norway uses a slightly different charging adapter than other countries in Europe."
"below zero' Kelvin? (is that you, Frank Herbert?) Centigrade? Farenheit?
People disincentivized into buying electric cars, increasing CO2 emissions, raising planetary temperatures until electric cars work.
newsflash: batteries generate electricty from stored chemical energy
Yes, it's related to the cold, but it also appears to be related to the specific issues of Norway's grid.
Some speculation is that the problem involves too-extreme fluctuations in the electricity provided by that grid and a charger-side software-mediated shutoff of charging. If that's the case, then this might be another charger issue that can be solved with an over-the-air "patch" like some of the previous problems.
While this is definitely a concern for Tesla and their Norwegian customers, it doesn't seem to be relevant to cars in North America.
Then we'll have to go out on Tauntauns
Well, as the joke goes here in Sweden:
Why are there no mental asylums in Norway?
It'd cost too much to put walls and a roof over the whole country....
Weird, eh?
I used to work in Northern Canada where all the US and some of the European manufacturers used to do cold weather testing. (The toolsets and options differ in North America which is why separate testing was done for Europe.) The Asian manufacturers were also doing cold testing there but their labs and warehouses ended up with all of the crappy real estate.
Did anyone seriously think the cold wouldn't be an issue? People need to get out of California and see what the rest of the world is like.

Thing is, a number of people have indicated that they have used third-party cables and those have solved the issue.
retrorocket.o not found, launch anyway?
Because many of us are interested. Tesla, love'em or hate'm are trying to sell a pure electric car without the compromises at a price at least a segment of the mass market can afford. There are ton's of technical hurdles to doing that and its interesting to watch theory and design encounter real world conditions.
Tesla is somewhat unique in this area too, Yes there is all electric Leaf and that strange i-Miev thing but neither of those comes anywhere near offering the range and performance characteristics of what most of us Americans expect from our ICE powered vehicles, in other words they make compromises, where as most Slashdoter's would be quite pleased with the Tesla compared to their current ride, provided it continues to live up to expectations.
Repeal the 17th Amendment TODAY! Also Please Read http://www.gnu.org/philosophy/right-to-read.html
No, meteorologists have understood the term Polar Vortex for decades. Weathermen, newscasters, and ratings-minded producers have only just discovered the term.
apparently the darling child of the automotive industry
What's with the snide side commentary? Tesla isn't the "darling" of anyone. Snide, obnoxious comments like this are pretty much du jour in any coverage. Everyone's gunning for them, simply because they're odd kid on the block.
A Tesla catches fire after hitting a piece of massive road debris or getiting into a crash, and it's a fucking national emergency, their stock tanks, electric cars are suddenly "unsafe", etc.
Meanwhile: do you drive a Ford SUV made in the 90's? Twice, Ford weakened the roof and support pillars to save money, against the recommendation of their engineers.
Drive a 90's Ford? Their ignition switches were substandard and could short out, causing your car to catch fire at random. 8.6 million vehicles: http://articles.baltimoresun.c...
Drive a recent GM truck? They've also got a "randomly burst into fire" problem; 370,000 vehicles: http://money.cnn.com/2014/01/1...
Just google "GM recall fire" or "Ford recall fire" and read page after page of recalls that affect hundreds of thousands if not millions of vehicles.
Please help metamoderate.
The name Tesla also holds a special place in geek culture. Choosing that as name for an electric car manufacture puts a greater expectation on the product.
What's next, are we going to post about a gasoline car not starting (am actually trying to help someone jumpstart their ICE right now, maybe I can get featured too)?
Anyways, just last week, someone made the trip from NYC to LA in his Tesla Model S, seen temps in the -20F range, and the car was just fine. I'm driving my EV in these same temps, no issues either (ignoring the lower range).
This is not a battery issue as some people seem to indicate.
I'd advise Slashdot readers to take their typical tack, and not read the linked articles. They are crap. However (again, much like Slashdot), the comments can be enlightening.
What I'm seeing there is:
a) This is not about the cold, or winter at all. Its been a problem since they started delivering vehicles in August.
b) Due to all the bad press (from poor journalists such as these) over fires from improperly overcharged batteries, Tesla charging cables now try to detect when a battery is fully-charged and stop the charging process.
c) They do this by looking for changes in the current flow through them.
d) Norway's power grid is so dirty that it is fooling the cables. That's the issue, near as I can tell.
I am in the middle of the polar vortex (-13F today) and haven't been having any issues charging my Tesla. I also haven't heard of anyone else in MN having charging issues. This really appears to be a Norwegian issue moreso than a general Tesla + cold issue.
Thing is, a number of people have indicated that they have used third-party cables and those have solved the issue.
So it's obviously that the skin-effect electrons are out of phase with the ones in the middle, or that the wire is in the cable backward because, as everybody knows, the electrons flow through wire more easily in the same direction in which the wire was extruded. And that, of course, is why Monster brand charging cables would solve the problems ;-)
Here's a must see link for us weather nerds...

make sure to tune into the 10 hPa setting and watch the polar vortex do its thing.
Thank you supercomputer...
Tesla (and battery powered cars in general) being fundamentally broken in cold weather...
A problem unique to the Tesla charging cables supplied in Norway is not "fundamentally broken" let alone having any significance to battery powered cars in general.
Tesla just needs to fix the problem and distribute new cables to Norwegian customers. Big fucking deal.
Methinks you have an axe to grind, and truth isn't important to you.
Norway, on the other hand, has 230 V between the phases and is completely isolated from the ground. With a perfectly balanced load you can expect ~127 V ground-phase, but the voltage can stray far away from that. This is an IT system (Insulated Terra). The Tesla charging cable is quite picky with the grounding, so it isn't working as it should.
This has nothing to do with the connectors, which are the same in Norway as in Germany or France.
Electricity is a funny thing. Had a problem with a piece of electronics that we make. The CPU wouldn't boot up if it was colder than about 20F. It turns out that the CPU has an internal voltage regulator that relies on an external capacitor. My engineer used an electrolytic cap, and at around 20F, the series resistance of the cap exceeded the tolerances of the CPU's voltage regulator and it went into a perpetual brown-out reset. Now, if the chip was up and running, it was happy and kept running, even if it got cold. So it's fixed now, but for some older hardware in the field with the problem, we don't send firmware updates between December and March. That's just one of many bits of stupid we've encountered over the years. In short, every piece of electronics you develop needs to be tested in the most absurd conditions you can find. And even that won't be enough. Never underestimate the creative stupidity of your customers.
My Nissan Leaf works perfectly during the Norwegian winter, and the Tesla owners I know here in Norway are very satisfied with their cars. They have had some charging problems, though. This has nothing to do with the connectors (which are the same as in Germany and France), and everything to do with the strange grounding system used here. In short: Both wires are live, we have 230 V between the phases (all three), and ground is, well, somewhere, who knows really. This is what seems to confuse the Tesla charging cable as it believes it has detected a ground fault and shuts down. As third party charging cables work perfectly, Tesla probably needs to redesign the charging cable in Norway and give a new one to every customer.
Perhaps you shouldn't give such strong advice on topics you are not that familiar with?
I live in Chicago, Illinois, where the outdoor temperature last night was -15 F. Windchill, -40F.
I had to promise my car that I'd wax it every weekend this summer if she would just start this morning.
My wife's car, 10 years newer than mine, did not start at all. Heavy snow followed by deep freeze is hell on internal combustion engines that are not kept in a heated garage overnight. I was sarcastically trying to make the point that suddenly these journalists have discovered that cars don't do well in record cold temperatures, but only the electric ones. I don't feel like reading this press release, but I'll bet the story didn't mention that probably 1/3 of the cars in Chicago couldn't start this morning.
You are welcome on my lawn.
