Volkswagen To Build Electric Versions of All 300 Models By 2030 (bloomberg.com)

An anonymous reader quotes a report from Bloomberg: Volkswagen AG Chief Executive Officer Matthias Mueller announced sweeping plans to build electric versions of all 300 models in the group's lineup as the world's largest automaker accelerates the shift away from combustion engines and tries to draw a line under the emissions-cheating scandal. Speaking on the eve of the Frankfurt auto show, the CEO laid out the enormity of the task ahead, vowing to spend 20 billion euros ($24 billion) to develop and bring the models to market by 2030 and promising to plow another 50 billion euros into the batteries needed to power the cars. Volkswagen is throwing the fire power of its 12 brands behind the push, aiming to catch up with the likes of Tesla Inc. and transform from a battery-vehicle laggard into a leader. Underscoring the enormity of the shift taking place in the industry, Mueller said VW will need the equivalent of at least four gigafactories for battery cells by 2025 just to meet its own vehicle production. At 50 billion euros, the CEO announced one of the largest tenders in the industry's history for the procurement of batteries. By 2025, VW aims to have 50 purely battery-powered vehicles and 30 hybrid models in its lineup, with a goal of selling as many as 3 million purely battery-powered cars by then. The transformation will pick up speed after that to reach the 2030 goal as economies of scale and better infrastructure help bring down prices and accelerate sales.

      EVs should be designed from the start as EVs. Battery at the bottom, everything else sitting atop it, and a shape having nothing to do with the constraints of ICEs. Motors located inline with the wheels that they drive - ideally 2 motors if you can afford it for AWD, otherwise FWD or RWD as per consumer preference (generally RWD). Etc. By the way, the reason that you really want two motors (beyond gaining the benefits of AWD without having to add a heavy front-rear linkage) is that you can gear them differently. This lets you "sleep" the motor that's operating outside of its ideal power band during normal operation (instantly waking it when you need more torque or traction), which means greater efficiency, and thus range. It also lets you combine both high acceleration at low speeds and at higher speeds (with a higher top speed) rather than having to pick.

The simplicity of your comment might as well have been, "ending usage of fossil fuels won't end hurricanes." That statement isn't incorrect, but it is a really simplified response full of snark to a really general way of thinking of a problem we now face. Which I get, it's bad for people to blame global warming for hurricanes that are happening now because it is not a 100% accurate way of talking about global warming. But I digress before we go down that rabbit hole any further.

    Now one day, and that day is long after everyone here reading this comment is dead, we will have ended the usage of fossil fuels for the majority of industrial and metro power generating. It will have more to do with the increasing difficulty of extracting fossil fuels and less to do with some holy war of clean vs dirty power.

But all of that I just stated plus a bit more ultimately will be guiding the world as to what we move to next. But to keep it simple, as it stands, coal is the first causality of this ever increasing difficulty of "access to." Will we ever use 0% coal? More than likely not, but as time goes on we will be less inclined to burn it for lighting someone's light bulb or cooking their Hot Pocket, we will all think that's just stupid considering it has a way better use in something like steel production. That's not today, but I would wager that it is sooner rather than later. So when I say causality, I don't mean death of coal absolute. I and many others mean it in these terms of being more conservative with the resource than we previously have been.

    Eventually, all fossil fuels will come to this point. It will seem really silly for us to use natural gas to heat someone's water, or for us to use oil to lubricate someone's car when both of those will be better used for heating a hospital or lubricating a wind farm or whatever. It's about the same state of mind that Slashdot seems to get into when we think about using Helium in balloons. It is a really silly usage of a resource that is limited that can be better used elsewhere.

Again, by chopping block, I mean that in terms of having to rethink its usage, not it's absolute demise. About 53% of the coal that we know about is still left for us to extract and is slightly economical to pull out of the ground. The remaining 47% of the coal that we do know about is just not feasible to extract economically and maybe that will change with some sort of technological leap. Even still, the coal we do know about is but only 30% of all the coal that is thought to exist on the planet. So that 53% roughly represents about ~15% of all the coal we think is out there.

    While electrons are easier to transport over distances, molecules are much easier to stockpile and transfer without loss.

    Merely even refining transportation fuels is a much less efficient process than charging li-ions.

    Carrying your own oxidizer with you is stupid when the air is 20% oxygen, not to mention that riding on a ton of fuel and oxidizer packed in close proximity is silly

    Li-ions don't work by oxidation processes, they work by intercalation processes. On one side you have graphite and/or silicon, and on the other you have nickel/cobalt/aluminum oxides. One or both of them are infiltrated with lithium ions in the interstitial space; the charge state is defined by which side the lithium is on.

    You seem to be under the mistaken concept that energy density corresponds to safety. Tell me, which is more of a hazard, 100kg of aluminum or 100kg of nitroglycerine? Now tell me, which is more energy dense?

    Here's the reality of fire safety in Tesla battery packs. They're so non-flammable that you can generally burn the rest of the car to the ground without burning the pack. Try that with a gasoline car. Gasoline fires in cars are extremely common. 152k gasoline cars catch fire in the US alone every year. Tesla rates of fires are far less than those in gasoline cars.

    What boggles the mind *to me* is that gasoline vehicles are allowed to store such huge quantities of a highly flammable fuel in just a big tank. No compartmentalization / isolation system, just pour it in, and there you go!

    And lastly: IC engines have consumables yes, but they are field-serviceable and don't require complete remanufacturing to maintain their efficiency.

    Simply not true. ICE efficiencies decline over time, and the level of cost required to keep them running at as-of-manufactured efficiency makes it impractical to do for most consumers. Older ICE vehicles are generally much less efficient than new ones. Which also, BTW, reduces range. Proper li-ion packs, like Tesla's, do lose range with time, but only slowly. Click on "charts". Typical degradation is about 4% in the first year, but much slower thereafter. A typical 5-year old car has only about 6-7% total degradation. It's hard to know at this point whether you can continue extrapolating such a slow decline slope over time, but it's at the very least extremely promising. Typical results from Tesla taxis with hundreds of thousands of miles on them are less than 10% degradation.

    We're talking "Now, not in a hundred years."

    BTW, it also sounds like you're under the impression that EVs remain unusually heavy. Check out the curb weights of the Model 3 variants. SR is 3549lbs (1609kg) and LR is 3814 lbs (1730kg). Its ICE class competitors (BMW 3-series, Audi A4, Mercedes C300, etc) come in a wide variety of configurations:

    BMW 3-Series: 1475-1770kg
    Audi A4: 1410-1695kg
    Mercedes C300: 1630-1715+kg

VW's announcement makes it sound like they are going to squeeze batteries and electric motors into their existing ICE designs.

    (And you can add Renault to the list, they share their EV R&D with Nissan - they developped the "Zéro émission" platform together).

    This as opposed to Renault Zoé which are modern Twingo design bolted onto the specially designed "Zéro émission" platform that they designed together with Nissan for this special purpose.

    Smart is another European brand that reuses part of Tesla's battery platform for their electric variant. (Haven't driven one though - only seen them around).

    (Both these last have batteries under the car like other "from the ground up" EV designs. Not batteries occupying whatever space happened to be free in the converted ICE such as the trunk as in the former).

    Yeah you can make it work somewhat but it doesn't sound like you will get a superior product that way. In effect they have announced that they are going to strive for mediocrity.

    ...or that they want to be the quickest to market.

    See how long it took Nissan and Renault for their "Zéro émission" platform.

    See how long it is still taking as of today for Tesla who are still in the process of extending their platforms range to cover Model 3.

    Designing from the gound up take time. A lot. And costs. Again a lot. During which time you'll still have to sell the old cars.

    VW's old cars got a horrid reputation after the scandal (in practice they're not the worst. There are other offenders cheating even more. VW just happen to be the one who didn't pay enough brib... huh.. sorry "who happened to get caugh by chance").

    (They've always have been about producing cheap cars fast, all the way back to the first beetles and minivan)
    Repurposing ICE cars is a quick cheap solution that can work RIGHT NOW.

    Then they can take time to specially built new platforms at a later time (as the upcoming 2018 electric rebirth of the VW minivan - which seem to be built on a newer platform)

      After Harvey, only one Supercharger station was noticed to have gone out, and only for a brief timeperiod. Superchargers survived serious damage to the buildings they were attached to - for example, one had a gaping hole in the hotel it was attached to, while another's adjacent building had the floor flooded with water.

      Irma was different - probably the single greatest power loss incident in US history. Ten million customers were left without power, and in certain parts of the state, virtually everyone. This took down about 80% of the supercharger network. That said, a day layer, about 75% of it is now up. The Marathon and Naples superchargers may have gone underwater, we'll have to wait and see what happened to them; there's a couple more that will probably go online shortly.

      How do superchargers keep the power on when it's going out for others, and get restored so quickly? Simple: they're on very high power feeds. Adding a supercharger to a suburban neighborhood is, power-wise, like building a large office building or small skyscraper. The Sarasota Supercharger, for example, running at full tilt would consume 1,5MW; unless they're located downtown or next to some huge industry, they're easily the largest power consumer around. This means that if the lines supplying them are out, then everyone is probably out as well. And in order to bring the lights back on to others, the supercharger is going to go online first.

      The other issue is that, like gas stations, charging infrastructure is spread out. But unlike gas stations, where delivery issues or the like may leave a whole region in short supply, power outages are spotty. So even if 80% of the chargers went out in an area, you still have 20%. But that's not the really important part; the important part is that 20% of outlets, period still have power. What it works out to in practice (and I know some people in this situation right now) is, the power goes out at your place, and if you don't have a backup generator, while everyone else is miserable in the heat, you use your car as a lifeboat; it can maintain the climate control for days, with no "idling", no worries about carbon buildup or carbon monoxide or the like. It leaves you mobile (getting great range at the low speeds you have to go when roads are covered in debris), and you simply need to find one place with power and you can charge. Which you almost invariably can. Doesn't matter if even the national guard can't get to you, let alone gas trucks, let alone whether gas stations have backup generators, whether or not their tanks were flooded, etc, etc - you can charge on any power outlet, anywhere - you just need to ask for permission.

      Of course, if you have a backup generator (say, natural gas), it's a moot point; you have unlimited driving at any point in time.

    Pumped storage is indeed the most usable solution, however, there are two things you simply must have to set up a system.

    1. Hills or mountains. You have to pump the water up hill and the higher up you can go the better. This means you need some natural topography that has significant elevation changes where you can build some kind of storage pool up the hill. Usually they take a hill, flatten the top to build a pool. You won't be doing this in the plains, which are nearly table top flat and cover a significant percentage of the country.

    2. Water source to pump from. Not only do you need hilly land, you need a ready source of surface water to pump up that hill. Again, this is not a given in the areas of mountainous terrain in the USA. Certainly the southwest doesn't work, it's hilly but there is no water.

    So you cannot just build these things anyplace as you indicated. In fact, there are really limited areas that have both things you need for this. Most of the Atlantic seaboard states from Georgia to Maine with the Smokey Mountains could work along with the states just to their west. There is a bit of Missouri (the Ozarks) that could work (actually already do this) and possibly the North West states of OR and Washington but after that, forget it.

    Then there is the HUGE environmental impact these things have and the dangers they create for the local area. You don't just take the top off a mountain and pump water up there w/o making lasting changes to the local environment. Plus you need a lower pool to keep the water when it's at the bottom of the hill, which has another huge impact. There is also a risk of failure and accidental uncontrolled release of all that water and the damage that could cause. And yes, that has happened with these things in the past. So, for safety, you cannot build these things upstream from where people are living, or risk killing people should an accident happen. This last requirement puts a HUGE limit on where you can put these things.

    Finally, there is the efficiency of pumped storage. By most standards it is abysmal. You get at best 87% efficiency and often no more than 75%. This means that you loose 13-25% of your energy input. Remember this is the BEST we can do and there is HUGE environmental impacts with this. Where I am a great proponent of pumped storage coupled with nuclear base load generation as a cost effective solution, I still do not think fossil fuels are going away anytime soon. However, as a peak shifting tool, buying power at night from base generation capacity then selling it at double to triple the price during peak, they might work out financially. But the start up costs are really high, and the energy storage capacity pretty low for the costs, so the break even point would be 10+ years away. So far, it doesn't seem they are very profitable.

It's too expensive compared to a Natural Gas powered generation plant, because the cost of CNG is so low and doesn't seem to be going up anytime soon.

Entropy gain is unavoidable and represents that part of the energy that doesn't get converted into the desired potential energy, but is lost to some other form like heat. The same is true for the process of changing chemical potential energy back into electrical power. Again entropy is increased, energy is lost to things other than electrical power.

    The laws of thermodynamics are about stream engines (I simplified it a bit for you), or in other words: idealized gases under heat an pressure.

    Or if you need more:

    The Wikipedia article unfortunately regularly gets rewritten in an incomprehensible state and then fixed again :D

    Efficiency of lithium ion batteries is about 99%.
    Probably some idiot edited the your wikipedia article?
    On the other hand some other idiot could have edited the thermodynamics article to my favour :P

    Your pick ....

    This means when you charge the thing, there is entropy gain, as you convert energy from one form to another
    Wow, another stupid argument.
    There is no entropy gain when you charge a battery. You reduce entropy.
    Uncharged battery: everything is chaotic distributed.
    Charged battery: everything is fine sorted, all charged particles on one side.

    Imagine a class of water, drop a sugar cube into it. Low entropy: everything sorted. The cube is in one corner. The rest is clean water. When the cube is gone: high entropy. It is distributed all over the place. With a "gradient" of sugar concentration which is high at the spot the cube was, and the lowest at the most far away spots in the glass. Recharging the cube to its old position: removing the entropy.

    Good luck with your half knowledge of Physics (and physics is probably the most simple natural science, until you hit Quantum Mechanics, Relativity Theory and/or String Theory)

    I hope for you, that you are never in a life threatening situation were some basic understanding of physics would save your life, and you fail.

    Regarding that wikipedia article, it seems that specific battery they used as an example has 80% - 90% efficiency. However that sounds not plausible to me.
    The Li-ion batteries in a car have close to 99% efficience. With charging equipment etc. that drops to 95% - 957% ... google is your friend.

    Anybody who's taking a course in thermodynamics sees the folly in that statement. Thermodynamics has application in ALL cases where energy is transferred or transformed, this means heat, electricity, chemical reactions, and/or potential and kinetic energy even. Just because they teach thermodynamics using heat engines does not mean it only applies to heat engines. The rules are general and discuss energy in all forms, not just a form of energy known as heat. You are gravely mistaken.

    You are wrong on your FIRST point... I rest my case because the foundation of your argument is patently incorrect, and thus your conclusions are too.

    Next you are going to tell me perpetual motion machines exist.... Because you found some snake oil sales man on Google that says so..

    No it has not. Reads the damn wiki article.

    A photon hits an electron, the electron changes "orbit". No energy "lost", no thermodynamics involved. The electron jumps back to its old orbit, it emits an identical photon, with same wavelength and energy: nothing lost, no thermodynamics involved.

    Last time some school kid with no physics in school wrote such nonsense, I gave two dozens of examples. Perhaps you find my old post.

    Thermodynamics has two single laws that have a general purpose application: the sum of the energy in a closed system is constant. Entropy is over time increasing.

    The rest of the laws are about ideal gases under heat and pressure. Should be clearly written in the wiki article, which you obviously did not read or someone rewrote it in bad/misleading english again?

    The core of the laws of Thermodynamics is a simple realization: if you convert energy to heat then it is hard/impossible to convert everything back into a "useful" energy.

    The law of Thermodynamics says absolutely nothing about converting magnetic energy into electric energy into electric fields into kinetic energy etc. p.p. Hint: get a damn clue what the greek introduction syllable Thermo means, aka as in Thermometer.

    Thermodynamics applies to all transfers of energy, which includes electrical power, batteries and heat just to name a few. Until we agree on that, I'm not going further with you because these concepts are fundamental.

    Thermodynamic laws you must understand the implications of are:

    Energy can not be created or destroyed (Conservation of energy).

    Transferring energy from one place to another and/or one form to another (i.e. doing work) increases Entropy.

    I go no further with you until we can agree on these fundamental laws of physics.

    It does not ...
    But if you believe otherwise that is your problem not mine.

    After all you are not working in electric engineering :D

    No, we can not agree on those laws. The first one is not a law, it is an axiom. One of our basic assumptions like conversation of momentum. I believe we only have those two :D
    The second one is already wrong. Transfer of energy does not increase Entropy. Why would it?

    No, I'm not currently working as an Electrical Engineer... But I have used my Bachelors of Science in Electrical Engineering as a electronics engineer in the past.

    We are at a impasse.. You won't agree to a common view of thermodynamics that I feel is fundamental and beyond debate, so we have no common ground to debate with. In my view you have already disqualified yourself as knowing anything about the topic being discussed, yet you make confident assertions of same which are simply wrong.

    So, as it says in Proverbs.. "Answer not a fool according to his folly"

    I'm done. Hope it works out for you. Full Stop

    Your "ideas" regarding Thermodynamics is not a common view.
    At least not amoung scientists/physisicst. No idea what you learn in american schools, though.

    Basically every time on /. someone takes refugee to the laws of Thermodynamics, the explainations and references he uses: are wrong

    In my view you have already disqualified yourself as knowing anything about the topic being discussed, yet you make confident assertions of same which are simply wrong.
    If you think so :D

    Funny that you think the physical laws about steam engines have any relevant application in electricity etc. except for running a steam engine to create electricity .... rofl.
