Tesla Issues Software Update To Extend Some Cars' Batteries Due To Hurricane Florence (electrek.co) 242

Tesla is temporarily enabling free Supercharging and extending the range of some cars' batteries for those in Hurricane Florence's path. "Tesla used to offer the option to buy a Model S or Model X with a 75 kWh battery pack software-locked at a capacity of 60 kWh," reports Electrek. "The option would result in a less expensive vehicle with a shorter range and the option to pay to remotely enable the longer range at a later stage."

Some owners on the Carolina Coast report that they've received a notification explaining the temporary new benefits: "We are temporarily enabling your car to access additional battery capacity, as well as free Supercharging, in preparation for Hurricane Florence. We hope this gives you the peace of mind to get to a safe location, and will notify you before returning your car to its original configuration in mid-October. Badging on your display may adjust during this period. Safe travels." From the report: This is a very cool move from Tesla. When they did it last year, it was misrepresented by many who focused on the software-limited battery packs -- saying that it means Tesla was screwing people over by limiting the battery capacity. The option was more about offering a less expensive battery pack without having to produce a different size pack, which helps streamline production. It gave buyers a less expensive option and they could always unlock the capacity later for a price. For those who decided to not unlock it, it now gives an opportunity for Tesla to let them have more range at a critical time by using Tesla's over-the-air software update capability.

  • What a strange age we live in...
  • Other than providing a less expensive SKU, one question I've seen is how they can afford to put a 75kWh battery in the car while only charging for 60kWh. There are a few reasons:

    • A 75kWh pack will last longer when never fully charged, reducing warranty costs.
    • A portion of the purchasers will upgrade at some point.
    • They don't lose money, they just don't make much (any?) on the software limited battery packs.

      they made more 75kWh batteries than 60kWh ones and rather than sit on them put them in cheaper vehicles.

        That's not the main reason that Intel sells cheaper CPUs. Intel uses binning, where they test every CPU they make to find out what it's maximum stable clock speed is, disable any cache or sub-processors that aren't working and then sell it as model X.

        In Tesla's case they have fully functional, tested 75kWh battery packs and just charge you to unlock the extra 15kWh. There is no binning, no difference between those packs and the cheaper ones, and a software upgrade is available at any time.

      My thought: Even if the ORIGINAL buyer doesn't upgrade, having the bigger battery would be useful for resale. In fact, if it was a lease from Tesla, they could unlock the full capacity for "free" and resell the car at the higher capacity.

        Unfortunately the software is locked down and if you try to hack it then Tesla will cut you off, disabling many of the features of your car remotely. That can include supercharging capability and telematics.

        Some people have made certain mods that Tesla tolerates. In particular the "bioweapon defence mode" is just a HEPA filter and a button that puts the fans on max temporarily, so you can buy your own HEPA filter costing a small fraction of the upgrade code and just turn the fans up manually.

    • I think their motive is not unlike other companies whose product-lines have a "Good, Better, Best" structure, with pricing to match. These levels could be imposed by manufacturing yields, or by an up-selling strategy.

      Sometimes a company runs out of "Good" and has to sell "Better" or "Best" in its place, in order to maintain the tier strategy. (For example, Intel may sell chips certified at lower clock-rates even though they might be overclockable.) But shipping "Best" in the first place, and enabling the ti

        Tesla is a bit strange though, because they fit a lot of hardware that isn't used to even the cheapest cars. For example the base model gets all the autopilot cameras and sensors even though they are not used. The car uses them to help train Tesla's neural nets as part of their full self driving development, but the owner can't use them and can't disable them either.

        That's probably one of the biggest reasons why the Model 3 Short Range, if it ever arrives, is $35,000 when the competition has bigger batterie

    Every engine manufacturer in the world does this. They'll have an 'iron set' which is a fixed engine block, turbo, injector, etc combination and the difference between 300 and 400 HP will be a software upgrade.

      Over the air?

    • Test equipment companies like Tektronix also have done this for a long time now; they'll build an oscilloscope with all the hardware 'bells and whistles', and you pay for license keys that 'unlock' the features you're paying to use.

    • Can you imagine if a real automotive manufacturer pulled this shit? Imagine if Ford, for example, offered to sell you an F150 with a 32 gallon gas tank, but had built-in software in the Engine Control Computer Module that would cut off the fuel pump and shut down the ignition system whenever it detects only 6 gallons of fuel, or less in the tank, in the hopes that you'll get good and sick and tired of the reduced range, call them up, and pay them some more money so they will remotely change the software so

    • I should also mention that, with the Model 3, there is no official battery size specification. People have inferred that the battery in the long range model is somewhere between 73 kWh and 80kWh, but no one knows the exact number.

      How does that fit into your issues with unlocking battery capacity?

  • "Tesla used to offer the option to buy a Model S or Model X with a 75 kWh battery pack software-locked at a capacity of 60 kWh,"

    The option was more about offering a less expensive battery pack without having to produce a different size pack, which helps streamline production.

    Can somebody explain how a 75 kWh battery pack in the 60 kWh version is cheaper than the 75 kWh battery pack in the 75 kWh version? If they are both the same 75 version... how is one 'cheaper' than the other?

    • Manufacturers do this all the time.

      Firstly, Tesla knows that some customers will upgrade.

      Secondly, there is a cost saving from having fewer options to manufacture.

      Let me blow your mind: every Model 3 has all the hardware required for the Enhanced Autopilot, but it is only enabled for those owners that paid for it.

    • One is 'cheaper' than the other because they decide to sell it for less money.

      Oh it's also more reliable, saves on manufacturing and supply management.

      It's cheaper in that lithium batteries last longer if you don't fully charge, or fully discharge them.

      By using a big battery and then ensuring it doesn't go below 10% or above 90%, it lasts longer, which saves money on warranty replacements. Depending on ambient conditions and driving patterns one might be able to degrade the 75 kWh battery enough, fast enough that Tesla would have to replace it at their expense. Limiting it to 60 kWh makes that a lot less likely to happen, thus it's cheaper to Tesla.

  • Something that you can simply put into the trunk (or frunk if you will), or something that you can pass to driver in need who ran out of electricity. Does something like that exist? If no, why not?

      I suppose you could use a generator. I would love the irony of powering an all-electric car with a generator.

      The issue is that batteries have a shitty energy density compared to gasoline, that's the biggest problem with EVs. A Tesla battery is about 500 kg for 400 km range. A gas car may use around 30L of fuel for that range, around 25kg, that's a factor of 20. It means you would need the equivalent of 20 jerrycan worth of batteries to match the range of 1 jerrycan of gas.
      And and there is the problem of cha

  • that's what i really hate about this, you already have the hardware, but it is restricted through software..
  • It's like on-disc DLC for cars.

  • It's not about what you do.

    It's about what you CAN do.

    How long before the FBI are insisting that you silently include a way for them to do the same and bring any Tesla they want to a halt or track it's location? They're doing it for everything from ISPs to encryption, you think they never would want to stop a car? Or that they wouldn't insist you do it under a serious NDA?

    I have a 2016 model Ford. I know that the car can't talk home because it just doesn't have that capability. Without the capability, i

  • A lot of modern ICE vehicles have cylinder deactivation, for example where a V-8 will run on only 4 or 6 cylinders to improve fuel economy.

    Maybe these companies can take a page from Tesla's book, and sell their V-8 powered vehicles, but software limited so they only use 4 or 6 cylinders all the time unless you pay for an upgrade to extra functional cylinders.

    Or not. Probably the buyers of normal cars and trucks are smarter than that.

  • Think about the implications for this. If they can increase range for a natural disaster, what's to stop "them" from decreasing the range or even preventing you from driving at all for whatever nefarious reasons you can think of? Don't be too proud of this technological terror you've constructed.

  • And then the manufacturer saying "hey we can toggle this bit here to turn on 2 more cylinders for the tidy sum of $5k". Very scammy for this, for locked cpus, gpus and basically anywhere where this mechanism is allowed and implemented

This is now. Later is later.
