Tesla Used A Third of All Electric-Car Batteries Last Year

cartechboy writes "We've heard about Tesla building this new gigafactory to produce battery packs for its electric cars. Heck, the company's current bottleneck is its ability to get battery packs for its electric cars. In fact, last year Tesla used a bit more than one-third of the auto industry's electric-car batteries, and that was with only selling 22,477 cars last year. Tesla is expanding its model lineup as quickly as possible with the introduction of the Model X crossover next year and a compact sports sedan in 2017. With the rapid expansion of its vehicle line, Tesla is going to need a crazy amount of battery packs, and quickly. Thus, the Silicon Valley upstart is building the gigafactory to engineer and produce battery packs in much larger quantities. If Tesla can remove the battery production bottle neck it's currently facing, the only question left will be market acceptance of a mainstream electric car."

    At current projected usage, Tesla is threatening to use up all the supply of batteries by 2016, and then there'll be trouble. I foresee a US invasion of Fremont in the near future as mayor Gus Morrisson continues to engage in belligerent talk and saber rattling related to commercial zone redistricting and increased parking fines. Rumors still abound regarding the untimely demise of his predecessor Bob Wasserman. Was it pneumonia, or something far more sinister?

    No grease
    No "fan" belts
    No noise of consequence
    No engine and drive train with 2000 parts
    No internal combustion engine repairs/adjustments
    Very low brake pad usage (unless you are 18 years old)

      Don't go crazy. There is still brake fluid in an electric car. And they still have radiators of various types for cooling purposes.

      When I take my Focus Electric in for scheduled maintenance, it's amusing to watch the service rep trying to find something they can actually do. So far the only items have been tire rotation and software updates.

      The mechanical brakes get less use because of regenerative breaking, but they still need fluid and pads occasionally. But besides those two things, I want to say that the only other scheduled maintenance in the first 10 years is cabin air filters- which you can easily do at home.

      Our Tesla is almost a year old (about 12k miles) and the only things that have gone into the car is air in one tire (until they fixed it for free), electricity, and windshield washer fluid.

      We did buy the maintenance plan (good for everything except tires for 8 years) and I'm sure it will need something, but so far its been basically nothing.

      It has an electric motor. Those do wear out over time.

      Brushless AC induction in this case. As long as they used durable chemicals in the windings and relgulate/cool it correctly, I'd expect the chassis to rust out before it needed more than a new set of bearings.

    Lucky they don't need a gigacrazy amount of battery packs, they'd have to build a super-duper-gigafactory.

  4. Not all Lithiums the same by foxalopex · · Score: 4, Interesting

    It's an interesting article for perspective but somewhat inaccurate. The article fails to point out that not all Lithium batteries are the same. The Volt for example uses such a different battery chemistry that it tends not to catch on fire even when punctured. The one simulated in lab fire occurred from the battery coolant catching on fire after it had a chance to dry out. (Took about a week.) The trade off is that the Volt's battery has lower power density which means that it holds less power for a battery its size. The Tesla S uses laptop batteries which have great battery density but have the obvious trade-off of catching on fire when punctured. An Iphone uses a Lithium Polymer battery which has some of the highest energy densities of all Lithium batteries. The downside is they explode when punctured. In a small device like a phone or tablet this isn't a big deal but in a Car which this would give it some amazing range, if it crashed it would literally be a bomb on wheels.

      >literally be a bomb on wheels

      No it is neither literally, nor figuratively a bomb on wheels. It will catch fire though, with plenty of warning and safety features, if punctured. As I understand if you were in the Tesla when it caught fire in the battery packs, you probably wouldn't burn to death.

    "Right now, the ONLY thing that is preventing me from getting a Tesla is that I have to travel longer than 500 miles a few times a year, and renting a car for a week, three times a year is too expensive an option."

    Renting a car for $500/pop three times a year is "too expensive" for a guy who has no problem dropping $90,000 on a car? I could see that the inconvenience might be a reason, but cost? We rented a mini-van a couple times a year for our family vacations because the sedan wasn't big enough. NBD.

    Odd.

    I'm a pretty firm believer that if you're going to drive 500 miles, renting a car is almost always a better option in terms of the wear and tear on your own car. [Obviously if you're leasing and under your mileage quota, things change, etc. etc.] I suppose it breaks down to what a week is (3-5 days? 7-10 days?) and how far longer than 500 is. Car rentals for non-luxury vehicles, especially for anyone who rents regularly are easily had in the sub-$40 range. Econoboxes are cheaper, but rarely enough cheaper to justify. On a whim, with no notice or club status, It's $44 a day for me to pick up a "mid-size" or "intermediate" (Sentra, Corolla, Fusion, Malabu) right now in my town.

    At $334 a week, if you're only driving 500 miles, you're probably not ahead.

    But 5 days and 600 miles -- Those 37c/mile probably come out ahead nicely with actual wear and tear on your car. AAA thinks so. *shrug*

    Even if it's only a small loss over driving your own car (in terms of big picture wear and tear), it might be overall worth it after switching to a Tesla.

    ...also, you get a Tesla :)

  7. Just Like Digital Cameras 20 Years Ago by onkelonkel · · Score: 3, Insightful

    This whole discussion on electric cars reminds me of digital cameras when they first came out. People act as if no technology ever improved over time. The first cameras were about 320 x 240 or so. Film purists were laughing. In order to get the same resolution as 35 mm film, you would need 5 MEGAPIXELS!!! which considering cameras were barely .1 Megapixels seemed purely ridiculous. No way is digital going to replace film! Of course the camera resolution doubled year after year and now digital cameras are ubiquitous and film is almost extinct.

    EV batteries will get cheaper and more powerful over time. Range will go up, vehicle prices will go down. Economies of scale and technological progress will see to that. As they get cheaper and better, they will make more sense to more people. People who might not buy a $40k car with a 120 mile range may well buy a $25k car with a 200 mile range.

    1. Re:Just Like Digital Cameras 20 Years Ago by Teancum · · Score: 3, Interesting

      The problem is that battery technology is hardly something brand new, and there has been a nearly 50 year need (arguably perhaps even well over a century) of having reduced weight and size of batteries. Some of the very first automobiles (see the Baker Electrics vehicle as an example) were electric even before Henry Ford started to build the Tin Lizzie. If Moore's Law applies after a fashion to battery technologies, instead of the typical assumed 2-3 year doubling/halving time that you are used to with computers, instead it is more like 25-50 years for battery technology.

      There have indeed been improvements with batteries with new chemistry coming up with better ways to store a charge. None the less, progress is very slow in coming and I only expect to see perhaps another double of the capacity within the rest of my lifetime. The Lithium-ion cells that used to be in laptop computers and cell phones made it possible to build something like the Tesla Roadster (and subsequently the Model S), which is why those vehicles now have much better performance envelopes than the Baker Motor vehicles I mentioned above. A century of progress does make a difference, but it is still slow in coming.

      Economies of scale will also help with the production of the Tesla vehicles, but until somebody makes the leap and builds the automobiles in the first place such economies of scale simply won't happen. Starting a brand new automobile company anywhere, much less in America, is so difficult that it really should be seen as a miracle and nearly proof there is a God all by itself. The current regulatory climate in America and Europe is bad enough that it is a miracle automobile companies even exist at all. For this reason, there is a definite lack of new entrants into the market (not that some people try, but almost all fail miserably). Tesla Motors is an exception and not a typical experience of a brand new automobile manufacturing company.
