Audi Recalls Its First Electric Car for Battery Fire Risk (fortune.com) 106

Volkswagen AG luxury brand Audi is recalling its first all-electric vehicle due to the risk of a battery fire. From a report: The company issued a voluntary recall of approximately 540 E-Tron SUV models sold in the U.S. because of a risk that moisture can seep into the battery cell through a wiring harness glitch, spokesman Mark Dahncke said. The company isn't aware of any fires or injuries because of the flaw, which affects a total of 1,644 models, he said. The E-Tron, which went on sale in the U.S. in April, is Audi's first fully-electric car and one in a wave of contenders from traditional automakers looking to challenge Tesla's dominance of the segment. While electric vehicles are no more prone to accidents or fires than gasoline-powered cars -- and might be less so, according the National Highway Traffic Safety Administration -- the lithium-ion battery technology that powers them is still evolving, and there is no consensus on safe system design.

    Yes, Audi has water leaking into their battery packs, and yes, the Jaguar I-Pace had a braking issue similar to Tesla's except that they can't fix it OTA like Tesla did in a week and instead will start sending out letters in a month to have people go into dealerships for updates. And there's no shortage of complaints about vehicle issues on the E-Tron and I-Pace forums.

    E.g.... talk is easy but making new tech is hard. Audi first started talking up the E-Tron in 2009, and we're only here now.

    But ultimately, it doesn't matter. A person who drives an E-Tron or an I-Pace is burning no more oil than a person driving a Tesla. And that's what matters. E.g. if there's some customer who didn't get a Tesla because they hate Elon Musk or whatnot and instead went and got an E-Tron or I-Pace... well, mission-freaking-accomplished.

    You'll get past your teething problems soon enough, Audi. Keep at it - the world needs as many EVs as it can get!

      Incorrect; the Tesla is measurably more efficient.

        Let me add boldface: no more oil than a person driving a Tesla.

        Yes, I-Pace and particularly E-Tron use well more energy per km than even the inefficient pre-drivetrain-upgrade Model X, despite having less interior space than the Model S. But that energy is electricity, not oil.

        Not every EV is as efficient as a Model 3 or an Ioniq. But they all share the key characteristic of not burning oil as fuel :)

          That would be true were it not for the fact that the nation's power grid is interconnected. Therefore, some portion of everyone's power comes from diesel no matter where you live. Therefore, unless there are EV owners who live in off-grid solar houses and charge exclusively at home, they all burn some amount of oil, albeit indirectly.

                  The claim was that "nobody" uses oil for electricity generation. I rebutted that with facts and now you are trying to move the goalposts.

                  Also, what is this "the grid"? Continental USA has multiple grids. 3, I think. Then, there is another grid for Hawaii and I have no idea how electrical supplies are organized in Alaska.

                    Although it is true that the major interconnects aren't synchronized, and thus alternating current does not flow between them, they are still tied together by HVDC interconnects, so power can flow between them. (I'm not sure in which direction.) I'm sure there are probably some minor interconnects that are not connected at

              I know for a fact that the cogeneration plant at UC Santa Cruz uses (or at least historically used) diesel power when it starts up, then switches to natural gas after a period of time. I know this because the natural gas generation capacity is lower than the diesel capacity, and when it switches, it sheds load. So when that cogen plant is powering parts of the campus during a blackout, you'll get a power blink, followed by power again, followed by poss

          That might be true if they were working as intended. If they are in the shop for recall, and the customer gets the gas loaner for the many weeks that the car has problems, then it doesn't quite work out as well.

    • So with a Tesla you keep getting over-the-air-updates to correct deficiencies in the product?

      Is this like with Windows 10?

    And will remain to be the batteries. Batteries suck frankly. They are heavy, slow to charge, lack energy density, wear out overtime and have a bad habit of catching fire or exploding when you mess with them. Tesla has done a lot to improve them but I think history will show that the Lithium cell is a dead end technology. EVs will really take off when something better is finally developed and makes it out of the lab. I have no idea what it will look like, I'm no chemist. But I think its plain to anyone who pays attention that lithium batteries are merely a stopgap.

      Ultimately, I agree. But I bought a Tesla anyway, and haven't regretted it a bit. Mind you, I went with a low mileage used one, rather than pay quite THAT much money out for a vehicle. The nice thing about Tesla is they've been selling battery powered cars since 2008 or so (first Roadster), and the Model S since 2012. So there's some history now to predict how they're holding up.

      In the case of the very first Roadsters? They're starting to find the original battery packs need refurbishment at the 10-11 year old mark -- mainly because they're starting to develop shorts due to insulating materials degrading from time and the weather. Meanwhile, companies have started offering refurbishing for these, independent of Tesla -- so at least you CAN fix one back up and keep using it, should you want to. Alternately, Tesla offers a v3.0 battery for them that has much more capacity and improved materials. That will set you back about $29,000 including the labor though, so NOT real cost-effective, except for the fact these are basically sports/collectible cars at this point. Most owners are using them for car shows and parades more than as daily drivers. If they got 10 years of use out of theirs, they might spend the $29K to keep it around another 10+ with a much improved battery that gives it 350-400 miles of range between charges.

      I figure my Model S has an 8 year, unlimited mileage warranty from Tesla with it, standard. So being a December, 2014 production date - it should be covered through the end of 2022. It's not likely I'd still own it that long, as I'd probably trade it in on a newer model with more capabilities by then. Whatever they sell by 2022 might be using a whole new battery technology, if Tesla is even still around? I mean, anything's possible.... At the end of the day, I bought this car because I knew I'd get a lot of use and enjoyment out of it while I owned it. And so far, I've done exactly that. I'm not super concerned about my "environmental impact" -- but I do like not having to hassle with stopping at gas stations anymore. (Charge the car overnight in my garage and it's good for my daily commute and whatever else I usually need to do.) And the performance is great too!

      • +1. I also have a 2014 Model S, with roughly the same plan to upgrade next year or the year after. Great car. Quiet, powerful, convenient. What's not to like?

      Actually the one thing the eTron does right is fast charging. It will pull a constant 150kW from 0 to 80%, faster than any other EV on the market.

      It's just a shame that it's also one of the least efficient EVs on the market too. If it was more competitive that charge rate could be in the order of ~700 MPH.

      • eTron doesn't do fast charging right. eTron just blacks out the top 20% of the battery capacity because they evidently haven't figured out how to safely use it yet.

        You could fast-charge a Tesla as well, it's pretty easy, you just charge to 80% and call that "100%".

    • I have no idea what it will look like

      Stability obviously becomes more and more important as energy density goes up... ideally it would be a seemingly-inert material that could be burned, smashed, shredded or immersed; bonus points if it has additional properties such as tensile and/or compressive strength or even is just a good thermal insulator...

      However, that could still be aiming too low... alleged 'tic-tacs' could be powered by this shit... or so the whack-jobs say. [wikipedia.org]

      Heavy?

      Tesla Model 3 BEV: 1,730 kg
      Toyota Mirai Hydrogen: 1,850 kg

      3 Similar cars are within 10% of each other.

      Energy Density? Who cares? You need to look at the vehicle as a whole not the individual battery. Sure gasoline is energy dense, but the whole power train isn't. A 400 horse power engine is going to be far more massive than 4 100hp electric motors. And if you want all wheel drive in an ICE you need complicated AWD linkages. You also need motor oil, you need an alternator, yo

      I think the advantage of a good EV design is that you can replace Li-Ion with Ultracapacitors or any other electricity storage solution along with some OTA software updates without changing the electric motor and much of other components. Tesla really leads this part.

    Oh, it's just a glitch? What an unusual word to describe the problem. I would expect a glitch to be a transient issue that goes away by itself.

    Seeing as it won't go away by itself, it's actually a fault - in either the design or the installation of the wiring harness or it's connectors.

      You're trying to be hyper-technical, but if you were talking about the inverter having a glitch, it would mean that there is unintended phase error. That would never just "go away," you'd have to fix the control system to remove the glitch.

      That happens all the time with PWM control too, not only with old or analog designs, but even with modern phase-correct PWM because of unexpected variations in capacitance or induction.

    Honestly, battery fire like this just seems to be the growing pains of the EV market. New EV manufacturers all have to learn the issues inherent with current gel-based lithium-ion batteries, much like they have had to do with gas tanks (nothing quite like getting rear-ended, splashed with gasoline and going up in a candle). However, after they refine the manufacturing process of solid state lithium-ion batteries and start using them in EVs then battery fires will be a thing of the past and all we'll have left is ICE carbeques.

      There was no fire, they just did extra testing on the wiring harness and found that under certain test conditions there is seepage through a harness that is designed to prevent seepage. It isn't actually supposed to get wet in the first place under normal operating conditions.

      This isn't about fires, this is about meeting specifications that are based on product testing rather than design. As you do more tests, you might have to modify the design. That's expected.

      So it is just growing pains, but it is more of an ache than a burn. ;)

        They did not "just do extra testing on the wiring harness". Five cars had water sensors in the battery pack go off. Given that there's only a few thousand E-Trons on the road for an average of perhaps two months each, that's a problem.
