Tesla To Build Its Own Battery-Swap Stations

Posted by Soulskill on Friday June 21, 2013 @12:50AM from the can-somebody-please-make-this-for-phone-batteries dept.

New submitter lfp98 writes "Just a month after the collapse of independent battery-swap company Better Place, the uniquely successful maker of luxury electric cars, Tesla, has announced it will provide its own battery-swap capability for its Model S sedans. The first stations will be built adjacent to Tesla's charging stations on the SF-to-LA route, and a swap will take no longer than filling a gas tank. From the article: 'A battery pack swap will cost between $60 and $80, about the same as filling up a 15-gallon gas tank,' Musk said. 'Drivers who choose to swap must reclaim their original battery on their return trip or pay the difference in cost for the new pack.'"

  And in either case, feigned indignation aside, if you wanted your car to be a quarter inch thick, stylish slab of aluminum or polycarbonate, it wouldn't be removable either. If for style purposes a designer, say, wanted to have an almost entirely glass vehicle and needed to hide the batteries in the various A,B, and C pillars, you wouldn't have them removable either -- because the design decision was a higher priority.

  Unlike propane tanks, it's a huge deal to refurbish a battery pack. You could "refill" your EOL battery pack for an $80 swap and get a new battery pack. Or, worse for the consumer, swap your brand new pack for a recharged pack that is nearing EOL. At $10k+ for a full sized battery (I'm guessing, too lazy to look it up), that's a pretty big fail for one side or the other.

  This battery swap system is going to fail. If you have to pick up your original battery on the return trip, how do you swap multiple times to drive cross country? Time limits? That won't work.

  The article is light on details, but it doesn't seem possible to always swap out with brand new batteries. Each battery pack keeps track of the exact number of charges and discharges, temperature levels, etc. So essentially the "age" of the battery is known. I would think Tesla would pro-rate the exchanges and charge based on how much newer the replacement battery is. The real question is whether customers swapping the other way (getting an older battery for their newer one) will be paid by Tesla for that difference as well.

  Propane tanks also don't have an infinite life. Over time they start to rust, the screw threads wear out, etc. One way or another that cost will be paid by the end user, either through a filling fee or in the cost of the fuel.
  A difference of course is that a propane tank's capacity doesn't decrease over time, which is a typical issue of batteries, making a swap harder.
  On the other hand indeed I'd rather see a station outright swapping batteries, and where you pay for the amount of energy you get. However that's tricky: battery capacities vary with age, and your depleted battery is not empty (as otherwise you wouldn't make it to the battery station), and the amount of energy to be added to fully charge it depends on that. Somehow smart battery monitoring electronics will have to take care of that. And when that's done, it should work quite reliably.
  The final step is going to be to have all car manufacturers agree on a certain standard, instead of having numerous competing standards. "One size fits all" is impossible as cars have different sizes, so maybe we should go for battery packs: small cars carry ten batteries, big cars carry 20, trucks 50. Like current gas tanks. Thinking of it, this could also solve the "rest charge" issue as the car could use the batteries one by one, starting to use one when the previous one is depleted. Or using 2, 3 at a time to get sufficient power, same principle applies.

  Unfortunately batteries won't with that speed for any reasonable definition of "soon". 150 miles will be about 50kWh. A 10 minute stop will involve 2 minutes of faffing around (drawing up, parking, connecting, disconnecting, etc) meaning 8 minutes charging time. 50kWh in 8 minutes would require a charging system delivering 375kW of power assuming it's 100% efficient.
  80,000 people live in my general area. Now let's imagine everyone has electric cars that can charge in 8 minutes. If we think how many people are fuelling their cars right now, there's probably right at this moment while I type - at a rough guess - at least 30 people putting petrol in their cars somewhere in my vicinity, and this is to fill a tank that lasts on average 400 miles. Reduce this to 150 miles and you're looking at almost tripling the "filling up" activity, so probably around 80 people simultaneously quick charging. This will require an increase in generating capacity of 30 megawatts. Our peak electricity usage now is about 30 to 35MW, so this effectively needs you have to double the generating capacity to do this.
  So for rapid charging electric cars to be practical in anything other than really small numbers, it'll be years off just because the grid will need a significant upgrade. This is before considering the engineering that has to go into designing a charging system that delivers 375kW and has to be hooked up by the average car owner safely, not a specially trained operator. It's going to require high voltages just to keep the currents reasonable (at 11,000 volts you're still looking at about 35 amps).

  If you're only driving about 300 miles or less, then it wouldn't be a big deal. This is the main problem with the idea of long distance travel with an electric car. The people advocating it apparently never do actual long distance driving. I'm talking like 1000 miles (which I have done before several times). At 10 minutes per 150 miles, that would be approximately an hour. I gather that the 10 minutes is assuming that you don't have to wait in line to charge up. In general, with a gas station, no waiting time, and only fueling up you could be in and out in 5 or 6 minutes. Combining that with being able to keep driving longer on a single tank, it's clear that there is a lot of work to do to sell people on electric cars for long distance travel.
  Electric 10 min/150m - 1000 miles: ~6 stops or ~60 minutes
  Gas 6 min/350m - 1000 miles: ~3 stops or ~18 minutes

  While I agree with your line of thought, I think you're missing a few things in your argument, which drastically changes your conclusion.
  1. of the 80k people living in your area, not all of them are going to be driving electric cars. some kids below driving age, some really old people who live in retirement homes, some unable to afford an electric car. let's say thatis 1/3 of the people. now you're down to 55k people
  2. of the 55k people, how many drive more than 150 miles one way on an average day? 4-5%? now we're down to 2.5k people. there are 1260 8-minute chunks in a week, so averaging 2 simultaneous users. of course double that to account for people not quick-charging in middle of night, and triple that for say peak times vs. off peak times, and we're still at 12 simultaneous users
  So we're looking at 4 MW additional load, or about 10-15%.
  I think the missing logic is that while normal cars must fill up at gas stations, electric cars can and will be mostly filled up at home (let's assume one has to pay a premium for the convenience of an 8 minute charge instead of an 8 hour overnight charge) or work (hey if you're gonna assume EV's are this popular it's not a stretch for offices to provide some charging capacity).

I'd like my car to be able to get me there with minimal trouble, but this might be in the range of these vehicles.

Perhaps comparing to a new Lincoln would be appropriate, but a new Honda Civic with a not-terribly-exciting engine can do 0-60 in 9 seconds with about 140hp. You have to look pretty hard to find a car these days that takes more than 10 seconds to reach 60MPH. Stopping distances are much shorter, and new cars corner far better than the old ones.

But that is changing as our company is moving out of Downtown and into the county next year and I'm also moving into a house closer to the new offices later this year. On a daily basis I could drive the Volt and probably fill up once a month. I do own farms about 180 miles from where I live that we rent out. So if I would need to go down there on a weekend to check and see how things are going, I just stop at the nearest QT, fill up and go. Same with visiting my Dad who lives 50.6 miles from my loft's garage to his doorstep.
  At this point what keeps me out of a Volt, or Hybrid of any kind really, is that I can't justify the price difference. The Chevy Cruse Eco is $20k less than the volt, similar sized car, and gets over 40MPG. That calculation has been the same for every Hybrid I've priced. I could go in tomorrow and write a check and walk out of the dealership with either. I could do the same for a Tesla or BMW or whatever under $100k.
  So this round is likely to once again be a gas powered car. But my planning on the car 8 - 10 years after that will be a gas-electric hybrid similar to the volt. I figure by that time the technology will be proven and will have come down in price enough that it will be an affordable option or hell maybe even standard in a dozen models.

  1) Battery technology sucks. You don't get enough charge from a single battery. It just takes too long. While driving around locally is ok, there is still range anxiety.
  2) If you constantly charge your batteries you will bugger your batteries. I don't run my fuel to the last drop. At around half a tank I start looking for the cheapest station and then will fill it. Charging a half full battery consistently is going to kill the battery.
  3) Cold weather or hot weather. Whether Musk likes to admit it or not, I like my car toasty, or cool in the summer. I don't live in the valley where weather is sunny and nice for the most part of the year. That drains the battery, as it drains fuel from my car.
  4) Battery replacement is expensive and requires rare earths. As demand for that increases so will the prices for batteries. Thus negating the benefit of electrical cars.
  5) We don't have enough power to charge all of the cars. If a highway has about 300 cars per hour (and that is not much), and every 150 miles a charging station is placed the parking lot will need to accommodate 75 charging cars. 75 charging cars which require about 96 kw will need 7,200 KW, or 7.2 MW. A single nuclear reaction outputs about 478 MW of power (remember this is nuclear not coal, or gas which are much lower), which means it can only provide power to 10,000 miles of highway. Add up in America how much highway there is and how many power plants will be needed. Now do the math with peak traffic of about 2,500 cars per hour and you have a REAL problem.
  Simply put electrical cars work so long as it is a "Ferrari", where only a few have it as a status thing. Once the masses start, the current technology will be crushed by the demand and we currently have no solutions.

  Electric cars are now pretty much in the same position as small cars were in the 70s. They will improve, and people will make their own decisions on which car is right for them.
  I have to disagree here. In my grandmother's era, most V8 engines struggled to break 100hp. Plastics weren't invented/widely used in cars, so they were very heavy. Putting a I4 of the era into an all-steel car of that era is laughable. If anything, expectations for power/weight have increased.
  Finding 0-60 times for old unmodified cars isn't all that easy, but the 1962 Lincoln Continental 7.0L V8 had a 0-60 time of 12.4 seconds with 300HP. Perhaps comparing to a new Lincoln would be appropriate, but a new Honda Civic with a not-terribly-exciting engine can do 0-60 in 9 seconds with about 140hp. You have to look pretty hard to find a car these days that takes more than 10 seconds to reach 60MPH. Stopping distances are much shorter, and new cars corner far better than the old ones. Driving requirements have actually gotten much more demanding, but weight and power advances have kept up.
  While everything you said may be entirely accurate (and seems so), it does nothing to refute bws111's claims. In fact, if you take your facts and align them to bws111's analogy, it makes perfect sense. Right now, battery technology and charging methodology are still lacking for mass-market EV adoption. Personally, I'm thrilled that Tesla is releasing cars with reasonable range for commuters (I drive 75mi each day I commute - 160 is probably the minimum I would want in an EV), but I really wish there were more Volt-style plug-in hybrids available - I think they're the easiest next stepping stone (after "Prius" - i.e., the one that came before - now hybrids are mainstream).
  Once battery tech gets to a point where it's long range enough for 99% of commuters and it's not $10k/pack, we'll be very ready for mass adoption of swap stations, charging points and all the economic activity that will enable/sustain it.

However, prior to that it wasn't that uncommon for 2.xL straight 6 cylinder cars to exceed 100hp and V8s were easily over 200. IIRC, a 1957 283cu in (4.6L) Chevy V8 was one of the 1st engines to exceed 1hp per cu in. Later V8s would exceed that considerably. Your 1962 Lincoln example is a bit low point given that the 1959 version of that engine generated 400hp.
  But that is not to say that I4 engines didn't exist the era of all metal vehicles even ones built by US manufacturers. They were just in subcompact cars like the Ford Pinto, Mustang II, or Chevy Vega. All of these were still lighter than many vehicles of today. In fact, if vehicles had retained their average weight that they were in the late 80s but had the same engine technology of today, we would be using about 30% less fuel as a nation. Crumple zones, air bags, side impact beams, noise reduction material, etc. all add a lot of weight not to mention that cars are bigger today than they were in the 80s.

  However, for someone who's already bought into the feel of an electric car, a serial hybrid keeps the same feel and vastly extends the range (and impromptu rechargability) . Plus the efficiency gain possible from multi-stage pistons or turbines is amazing, if you don't have to care much about the power/weight of the gas engine given it's quite small to begin with compared to the electric.

There's no practical explosion or very-high-energy fire with metal hydrides, which is a real benefit over gas or current high energy density batteries.

  I don't have a Model S or a Roadster, though I'd love to if I could. I do, however, get irritated at the utterly irrational bullshit spewed by people who are convinced that no EV ever produced will ever work for them. Tesla could make an EV that does 0-60 in 1.5 seconds, has a 4,000 mile range, sees 1% range reduction in Antarctic Winter temperatures, works underwater, flies in the air at Mach 5, self-drives, self-parks, seats 12 comfortably, and there would STILL be people here bullshitting that it just won't work for them.
  Cut the crap. If you have an actual issue with the functionality of the car, spell it out and make damn sure it makes sense. Then consider whether it applies to more than 2% of the other 300 million people in this country. I've yet to see someone come up with a real problem with these cars; just imaginary scenarios that don't exist in real life.

  Right now, battery technology and charging methodology are still lacking for mass-market EV adoption. Personally, I'm thrilled that Tesla is releasing cars with reasonable range for commuters (I drive 75mi each day I commute - 160 is probably the minimum I would want in an EV), ... Once battery tech gets to a point where it's long range enough for 99% of commuters and it's not $10k/pack, we'll be very ready for mass adoption of swap stations, charging points and all the economic activity that will enable/sustain it.
  The low-end Tesla Model S will do over 200 miles, so your 160 mile requirement is met. The Supercharging stations are free and will add 150 miles of range in 20-22 minutes once the upgrades are completed (per Musk). The existing stations take a whole 30 minutes. 20 - 30 minute stop after 3 hours of straight highway driving? Completely reasonable, especially since such trips are rare for just about everyone.
  As for it supporting 99% of commuters? Ok, so the low-end Model S has a range of >200 miles (Tesla says 230, EPA says 208, let's say 200 on a bad day). Per the US Census Bureau (http://www.census.gov/newsroom/releases/archives/american_community_survey_acs/cb13-41.html) there are just 600,000 people who travel more than 50 miles each way to work. That's 0.2% of the population and that's half the range of the Model S on a bad day. This puts the likely number of people commuting >100 miles each way somewhere in the range of 0.001% or so. For those people, (all ~3,000 of them), the low-end Model S probably won't cut it unless they can charge at work. If they're commuting over 200 miles each day to work, they're likely not working at a car wash, so there's at least a decent chance some percentage of them will be able to charge at work and complete their 3+ hour daily commute. (This, by the way, is ridiculous. If you're commuting 3+ hours a day to work, sleep in your office or your car and join the YMCA so you can shower and change, then go home on the weekends. Or FFS move closer or telecommute.)
  So yet again, the Model S meets your demand for range. Is the pack expensive? Sure, for now, and so's the car. But that isn't the point; the point is that it's an EV that's affordable for a sizable group within the US (all those people driving Audis and BMWs) and which actually works in the real world. By your own standards, it works. By any reasonable measure, it works. Unless you're commuting 200+ miles round-trip each day and putting 70,000+ miles on your car each year (and according to the US Census, you aren't), the Model S works fine for nearly everyone.
  If you come to me and say that the Nissan Leaf (75 mile range) or the Ford Focus Electric (76 mile range) or the Smart ED (68 mile range) won't work for a big chunk of the US population and I say you're absolutely right. I'd be afraid to drive the thing to the grocery store in a major metro area for fear that I'd get stuck in traffic and end up calling for a tow. 60 miles 'til E is when I fill up my gas tank. Why? Because I don't like stopping unexpectedly or worrying unnecessarily about when I'll run out. But how in the world can you say that with a vehicle that goes 200 miles or more between charges and which starts out every day fully charged? It's the perfect daily commuter; you'd -never- have to fill the thing up at a 'station' of any kind unless you were going on a long trip. Consider taking the 7-minute stops at the gas station you'd typically make once a week (that's over 6 hours a year pumping gas into your car) and using a quarter of that time to plan the two road trips a year your average Joe does that go over 200 miles. Find a Supercharger station along the way, stop for 20 - 30 minutes (have a bite to eat while it's charging), and complete your trip. If that's too much trouble for you, take some of the money you've saved from not filling your gas tank (in the range of $2,000/yr average) and rent a really nice car for the week and then realize what a pain in the ass it is

  “The chargers are generating energy cumulatively throughout the course of the week, and it cumulatively adds up to more than what the cars consume,” said Musk. “So it's actually capable of going completely off-grid,” and of continuing to charge cars when the power goes out.

  The Model S costs significantly more than my current car (and I actually have a pretty expensive car), but provides fewer capabilities, particularly in terms of range. I'm not going to pay more for less. Seems pretty silly to me to do so, wouldn't you think? I think that line of reasoning is about as common sense as you could get.
  You don't want the Tesla because it is more functional than existing vehicles, because you know it isn't, not yet anyway. Certainly the infrastructure you are presenting doesn't even exist yet, and for years will be limited to certain corridors. You want it for some external reason that has nothing to do with it's capabilities as a vehicle. Which is perfectly fine, but I just don't share your motivation in that regard. Or, "good enough" for you, is not "good enough" for me.

I have my own requirements, and they are not even close to being as ridiculous as any of the things you suggested.
  Putting all that aside, what I am not suggesting is that Tesla has to suit me to be worthy of existence. They certainly have a market, and I hope they are successful.
  However, if they want me or someone like me to actually buy their car, then I have things I want to see, and I already get those things, so I know they aren't impossible or even really all that hard to do.
  With that in mind, I wonder if your real problem is that someone is suggesting in text that they don't want to buy the car. In other words, a fear that dissent will cause them to disappear. If that is the case, you have more to worry about than my fairly modest range requirements.
  I'm not against the cars, they're just not yet there for my current needs. In no way am I clamoring for their dismantlement because I personally don't have a use for them.

  Man you just can't catch a break.
  Few or no "regular" mass market car needs more than regular gas.
  Some luxury or performance cars, with a high performance engine with high compression ratios, will run more efficiently with it, but even then its not required because of the anti-knock sensors that are standard and have been for a while now. you lose a little performance, but they adjust the timing.
  It also requires... you know... a knock. All modern cars have knock sensors. However, putting regular gas in a high compression engine regularly will still eventually damage the engine because the engine management computer has no way of predicting knocks before they happen. In order to set the timing to the grade of gas, the engine still has to periodically advance the timing until the knock sensor goes off.
  The knock sensor is there as a backup (e.g. in case you are in the middle of nowhere and can't find premium gas... or somehow the grades got mixed up at the pump... etc. etc.) It is NOT there so that you can save a few pennies by habitually pouring low-octane gas into an engine designed/timed for high octane.
  With the recent surge in the popularity of small turbo engines, your advice is shitty and you should feel bad for giving it.

  High octane-rated fuel does not spontaneously combust (or actually requires higher temperatures and pressures to spontaneously combust). Spontaneous combustion means all the fuel (essentially) ignites at once, which causes the "knock" sound. Instead, you want the fuel to ignite sequentially. How this happens in a gasoline engine is that the spark from the spark plug ignites some fuel and the flame front travels out from that point throughout the cylinder. So, while it is true that you do want slower combustion, the higher octane rated fuel does not actually burn slower than lower octane rated fuel. You are just trying to prevent the fuel from burning real quickly (spontaneous combustion).

  It really just depends on what part of the US one lives in. States like California have a high population density and minimal agriculture so the average citizen in these areas have access to everything they need within a five-mile radius and have gas efficient vehicles so gas prices really aren't as important to them. Go into the midwest states however and you'll find low population density and more agriculture, and gas prices will drop accordingly. Because when you have to drive ten miles to the closest store in a truck that gets four miles to the gallon, you are much more likely to get upset about gas prices than someone that daily drives maybe five miles in a vehicle that gets thirty miles to the gallon.

  Even the GasBuddy data which the local news likes to quote is easily manipulated. Their average price is based upon people submitting the daily advertised prices based on the stations' posted prices. But these numbers aren't weighted by sales volume. So all a few big chain stations have to do is to jack their prices up to drive up the calculated average. They may not be selling much, but GasBuddy doesn't have that data. And the brand name stations take turns being the sales loser. That's why one local brand name station occasionally goes from being a good deal to suddenly being $0.40 or $0.50 over the market average. No sane people actually buy that gas (unless its an emergency).

The point is, since the battery alone makes up a significant portion of the vehicle cost, this would be a way to reduce the sticker price and make the car attractive to a broader market.

I don't get what the problem is...
There *already* exists a system for returnable starter batteries (at least here in Germany), which works similar to returnable bottles.
Just build an automatic underground storage for batteries, which automatically keeps the batteries charged, using solar power (cheap!), and automatically marks all batteries below a certain performance (amount of energy it can store and wattage it can deliver) for recycling. Then every month or so a truck comes, and replaces all the dead ones with new ones.
You drive above it, a machine (e.g. a on a rail) detaches the empty pack (if it is of the right type), moves it to the storage, takes a new one out of storage, attaches it meanwhile you pay using the terminal, or a mobile phone app... and off you go.
You wouldn't even have to leave the damn car!
The price would just be the money to keep the refill stations and batteries alive (= recharging, repair, replacement, modernization), divided by the number of clients, plus your profit. That's it.

  If you're commuting then you're not going to use this service. You plug in at night when you get home and unplug in the morning. It takes about 10 seconds to do. The electricity used for my daily 18 mile commute costs around $40/month with my Tesla model S. It's cheaper to drive than my Prius. I also have the option to charge for free which takes 30 minutes for 80% charge. The only time I need to use supercharging or possibly a battery swap is if I do a road trip like I'm planning up to Lake Tahoe. The battery swapping will first be set up for people driving between LA and the Bay Area. As for batteries wearing out, the batteries are rated for 3000 full charge/discharge cycles which is the equivalent to around 750,000 miles when you assume 250 miles/charge (EPA rated 265).

short-term battery loan by jschen · 2013-06-21 03:10 · Score: 2

The way I see it, the best use of the proposed battery swapping isn't for a quicker charge. It's to allow one to borrow a battery to use/abuse during a road trip. If going on a long road trip, rather than subject one's own battery to the added stress of multiple fast-charge cycles, one has the option to borrow a battery for $60-80 and subject that one to those conditions. If we assume that a new battery is ca. $10k, then the rental is under 1% of battery cost. If a long road trip with multiple fast-charge cycles causes sufficient battery wear (or even just lots of anxiety about the potential effects), then for $60-80 one can get a loaner battery.

But what I really want is a tiny turbine generator. As in 5-10 HP. This would be enough that if I screw up and am 10 miles from home when the car basically dies I can just pull over and read for 20 minutes to build up enough charge to get home.

People will blah blah about the volt having an onboard generator but that is basically a full sized gas engine. I am talking about something that would fit in shoebox or two with a pint or two of fuel. The range of the Tesla is great and would meet 99.9% of my needs nicely. But I can see the day when the kids didn't plug it in leaving it at 40% when I need to pick up my wife at the airport. I would look at the range and with gritted teeth see that I have almost exactly the range to get there and back. So I would kick in the turbine and buy a few extra miles. I am enough of an optimist to make stupid trips like this. Also it would allow me to do the walk of shame to a nearby gas station if I even ran down the fuel.

It looks like Tesla properly understands the value of combining quick fueling with slow charging! The only thing they have to do is create a system (likely subscription) so that you don't have to pick up your original battery pack. The battery pack should belong to the fueling company and your subscription should provide the insurance/assurance against battery pack damage.
Battery packs will be standardized within a small group of performance levels (just like today's gasoline) and the only other variance between vehicles will be the *number* of battery packs swapped in/out.

Arizona vs. California gas by tlambert · 2013-06-22 01:50 · Score: 1

Arizona doesn't reformulate their gas. California dilutes their gasoline with alcohol and other additives, and before that, MTBE, primarily due to lobbying by Chevron, since it allows them to manipulate the gas market in California by not allowing out of state refineries to ship gas into California.
You will find the same mileage improvements in states that do not reformulate during winter months (so called "winter gas" vs. "summer gas") if you refill your tank there during those months.
By the way, California gas is significantly worse for your engine, fittings, and gaskets than non-reformulated gas. This is one of the reasons there is a separate "aviation gasoline": to prevent an engine failure due to a hose or gasket failure due to it being eaten away by the alcohol or other substances.
Here is the reference for my statement about Arizona not reformulating:
http://www.epa.gov/region9/air/phoenixcbg/
"EPA published a separate notice approving Arizona's opt-out from the federal reformulated gasoline program, effective 90 [days] after the effective date of this final rulemaking."
