content: In the EEVblog forums I have seen a large number of posts arguing if EVs or ICE cars are less costly. Here's actual real world proof that EVs are in fact 8 times less costly to drive and maintain than ICE vehicles. This interview is from 2017 and I would have thought some smart people would have seen and posted this by now.What a story. This kid at 16 wants a Tesla Model X. With only $300 in his pocket he's able to get a Model X and starts a business of driving people who don't want to fly. Sounds like he was doing well as he know has 9 or 10 Tesla's in his fleet. Brilliant!He talks about "burning" out Tesla batteries by fast charging them to 100% 3 and 4 times a day. Teslas in his fleet are some if not the highest mileage Tesla cars there are.It's going to be interesting to see the replies from the ICE Luddites out there who will find some twisted way to say this kid is wrong.But the facts are the facts. This kid has the cars, and has the data and has done the calculations to prove Tesla EVs are EIGHT times less expensive to fuel and maintain than a compatible ICE vehicle.https://www.youtube.com/watch?v=VspjxmsIqxo&ab_channel=D%C3%86rik

content: There are few, if any, who say that operating costs are not lower. It is total cost of ownership that is in dispute, and that is harder to compare. Some is clearly statutory and subject to change, such as the subsidies for EV purchase and the lack of road use taxes for EVs. I will say that I have been pleasantly surprised by the life of the batteries. I was quite concerned that battery cost would dominate operating cost. While the data is not all in on this, the answers to date are hopeful.

content: You are right, there are many ways to look at this. But, It's hard to argue what people might say with a vs. a smart kid who has actual detailed data for 9-10 Tesla cars. This kid, (prior to covid) appears to have had a nice growing business based.

content: For the cost of one way trip with his Teslas you can rent a car for an entire day and buy the fuel for the one way trip.Also his service is called tesloop, his whole marketing depends on driving Teslas ... he doesn't drive any comparable cars, he has no numbers for them and he has a clear commercial incentive to talk up Teslas.This has nothing to do with being a luddite, just not optimistic about human nature.

And the kid includes a driver so one can sleep. And the kid picks you up at your home. All something rental car companies do not do.Hard to believe out of all of the ICE transportation businesses that are out there they don't have keep any records of operational costs. I know they do, because years ago I worked for one and we had to track fuel and maintenance costs against the mileage driven. If those number don't exist, how could he do a comparison?For a guy who is promoting Tesla products why does he talk about the times when the cars just died and his riders were left on the side of the road? He's sure talking smack about the product you say he's promoting.

His fleet of Tesla cars have collected years of valuable data we can use to do a comparison between ICE and EVs.I am an EV owner for several years now. While I am just one data point, and don't have detailed records I have collected enough empirical evidence to know an EV is defiantly much less costly to fuel and maintain than an ICE vehicle.

content: Quote from: DougSpindler on September 07, 2020, 07:34:36 pmOk, I can see the data consists of just a statement in the video. Just accepting it as true.To be objective, the video provides a datapoint about high mileage vehicles. That will make EV's look good as the lower operating cost will dominate depreciation. I think if you want to make a case for the average person, then this video is irrelevant.The running cost for an expensive new vehicle which doesn't do large miles/year, does not have a very big impact on TCO. It is depreciation that dominates. Teslas fare poorly here as they are relatively costly.In general I think it is reasonable to say that an EV costs more than a comparable ICE vehicle. I don't think that will be the case for too much longer, but it is a problem for EV's right now.There may be an angle that EV's hold their value better, have you collected any data on that?

content: Quote from: DougSpindler on September 07, 2020, 06:22:05 pmAgree. Not a fair comparison. But apples and oranges comparisons are rife here. He mentions one data point, $11K for 311k miles in a Tesla Model X. Then mentions maintenance costs for a Lincoln Town Car for comparison. While I agree that the cost for the Model X will be less than for a comparable ICE car, a Lincoln Town Car isn't really that vehicle. He references $30k as I recall for the Town Car operating cost, which doesn't sound unreasonable to me. But he also referenced $110K as the cost of the ModelX. So the total cost of ownership is very comparable.Comparing the cost of a single seat in a small bus (which is what his service is) with Uber and other services which dedicate a vehicle to a passenger is one of the unfair comparisons. Unfair when comparing operating cost. Completely fair when comparing the cost of getting a ride.He seems to be doing OK as a business, but little of his business model depends on an EV. A cooler full of snacks. Charging cables. A driver. Curbside pickup. All possible with either vehicle type. Assuming purchase price is the same for ICE/EV (not close to true at the moment, but just let that ride for the moment) his advantage is the operating costs, a $20k savings over the 311k miles. Better than a thumb in the eye, but in a world where most businesses look to double or more their investment over a similar time period this looks pretty lame. Now it worked well for this kid because he was able to take advantage of a program that Tesla has since discontinued (apparently wasn't working financially for them) which allowed him to return vehicles regardless of mileage. Effectively no up front investment, making that $20k return much more appealing.I agree, businesses know what it costs to operate their vehicles. The fact that they still largely operate ICE indicates that either their data doesn't show a compelling reason to switch, or that they see significant uncertainty in EV total cost of operation. Many businesses are experimenting with EV, suggesting that the latter reason is significant.

content: I think it is fair to say this is an experiment in progress. And to complicate matters, the technology is continuing to change which makes just complicates the analysis. We have so few data points with EV cars over 500,000 miles we just don't know. And for the few cars in the 500,000 mile range those cars have the "older" battery technology which doesn't really can't be applied to the "current" battery technology.With that said, I think we do have two very credible independent data sources which can be trusted. (Sandy and the Tesloop fleet of cars.) And Yes, Tesloop is not your "average" driver, but it's the only data we have to work with for a high millage EVs. It's going to be another 5 to 10 years before we really have enough data and miles on the batteries to really know. I think the kid from Tesloop has really did his homework and has clearly demonstrated there is a substantial cost savings with EVs.

content: @CatalinaWOW I think for these big transpiration fleets it's a matter of "trusting" EVs reliability. I was very reluctant to buy my first EV so I leased it. When the lease was up without hesitation I purchased my next car which was an EV as well. (No more ICE for me.)Nobody wants to be first when it comes to new technology. As the kid said in his videos Teslas failed on him leaving passengers stranded at the side of the road. Hard to run a business when the product you are using to make money fails on you.I'm seeing small fleets like private/corporate Uber type companies all using EV to shuttle employees around corporate campuses. They tried, and now trust the technology. As Sandy said in one of his videos the car industry is a "good old boys" network. If you buy what you've been buying and it works you won't get fired. These young kids aren't into that. They look at ICEs as being like a rotary dial phone that's destroying the planet. They are the ones who are changing the car industry.I hope you saw the video where Sandy explained when the economy was bad and new college grads were not being hired by the car industry Elon/Tesla hired them. (So did Sandy.) They brought new technologies and ideas to the table which is why Tesla is so brilliantly designed. There are those of us who might not like Elon or Tesla, but we should give credit to Tesla engineers and respect what they have accomplished. They totally disrupted the entire car industry. And don't you think it's about time someone did? It takes a disruption like this for the entire industry to evolve. The is capitalist Darwinism in action. This is survival of the fittest. I would have thought Tesla would have gone bankrupt long ago. Now companies like Ford don't want to be a car company with technology. They want to be a Tesla, a technology company that makes cars.This has to be one of the best experiments ever and we are right in the middle of it.

content: Doug, I almost completely agree with you. And your last sentence defines the element of disagreement. You say we are in the midst of a giant experiment. I agree totally. But you seem to think the experiment is over and the results are in, where I think there is much data still to be collected.Even things that won't be apparent until EVs grow in scale to match current ICE (assuming it goes that way). Many "features" of ICE did not become apparent until truly large scale was achieved. Including the ability to change the atmosphere. I don't know if EVs have any similar "features". Nobody does.

content: @CatalinaWOW I didn't mean to imply this experiment is anywhere near to being over. It's gong to take 20 if not 30 years or more. That's about what it took when cars were replacing horses. Steam was the proven reliable technology. Electricity and liquid hydrocarbons were the "new" kids. Electric cars were reliable, didn't scare horses with backfires and there were cleaner. Cars until Ford mass production were only for the wealthy. It took good 30 years before everyone gave up and steam and EVs.And here were are about 100 years later and it's almost the same experiment except lets swap hydrogen for steam.

content: Quote from: CatalinaWOW on September 07, 2020, 06:00:31 pmYes, and that is the trick.Great for those owners who get EV's subsidised by the government, sometimes massively so.Here in Australia with near zero tax breaks, the cheapest EV on the market is $54k driveaway. In comparison there are more than half a dozen ICE cars under $20k.That being said, personally I can see a tax value proposition for an EV for myself, and will almost certainly get a new Hyundai IONIQ shortly. I should come out ahead over the long term.

content: Quote from: EEVblog on September 07, 2020, 11:26:42 pmNot in America. Are your tanks smaller? (Because they sized in liters and not gallons?)It takes us a minute or more to get or credit card authorized at the pump. Longer if you are paying with cash or have to present the card to the station agent. Then it takes almost a minute for the pump to start. Then you've got about 5 minutes to fill the take and keep topping it off until the gas right to the top of the filler tube. Then you have to put the cap on hand the pump up and get your change if paid with cash or get your card back if it had to be presented.And all of this is considering there is no line. American will line-up to pay $0.10 less per gallon of gas at the station across the street and then pay the credit card surcharge of $0.10 gallon making the cost the same as the station across the street. Aren't we smart?

A small car like my Toyota Corolla has a small tank, don't think I've ever filled it with more than 35L.The wife's Nissan Dualis has a much bigger tank, something like 45L to fill up. But still under two minutes.Every time I'm at the pump I like to guestimate flow rate by counting the seconds. Only very rarely would I encounter an old pump that's slower than 1L per two seconds.QuoteThem your system sucks. Last time I was in the US you had to go into the station first and give the attendant your credit card or get it authorised or something and then go back outside to fill up. Completely stupid system. Here you just lift the nozzle and fill up, might take 10 seconds for the attendant to reset the pump. Rarely a line in the shop to pay and then it's "tap-n-go".I can fill up and be out of the petrol station with 500km worth of fuel in well under 5 minutes, including going into the shop to pay for it and getting some snacks.There is no way for the forseeable future that EV's will even come close to refill time / range of ICE cars. Petrol is just too massively efficient.

content: I'm in the San Francisco Bay Area. No way you can do it under 5 minutes unless you are not paying for the gas. We are talking from the time you stop and open the car door, until you are back in the car, door closed ready to get back on our California freeways to speed down the highway at 10 mph along with the millions of others doing the same things.Most of the pumps here do not accept ApplePay/GooglePay or have contactless card readers. You have to insert the card, wait. Then enter your zip code, wait. Next you enter your rewards number (depending on where you are buying your gas). Wait again. Select the grade of gas wait, stick the nozzle in the car and fill the tank. My vehicle tank size is 21 gallons, that's 80 liters for the rest of the world. Just looked this up, gas pumps in the US are limited to 10 gallons per minute. So I guess you are right, time to fill just the tank would be just over 2 minutes......Never mind.Maybe I spend the next 5 minutes trying to get the gas cap on. Sure seems like more than 5 minutes to me when I get gas.Next time I get gas, I'm going to time it. From the time I open the door and get out, until the time I get back in the car.You do realize in Oregon I know it takes longer..... Anyone know why?You can't pump your own gas.

Not every location has superchargers, and some share maximum capacity.Power infrastructure aside, if everyone switched to EV's overnight then it would be chaos to fill up anywhere but home.Not all EV's are equal on fast charge times either, not by a long shot.The IONIQ I'm looking at getting takes 40min @50kW to get to 80% for example. 30-40min for the LEAF, once again to 80%.Tesla quote 30min for 270km for the model 3. I don't know where you get your 17min from.If you are looking at eating up the miles on a road trip then EV's are very far away from ICE cars.

content: Doug, EV are good and arguably a better economic value at this point on time. Likely to be better over time as EV costs go down and ICE costs go up. So there is no need to use phony estimates to make ICE look bad or EV to look better.EV fueling time is attractive when you can charge at home overnight. It does take a bit of time daily hooking it up and disconnecting it. My guess would be a little under a minute for able bodies people with a reasonably convenient setup. A bit less if you push, a bit more for those with their hands full and not yet fully awake. So around five minutes a week for most commuters. But that isn't the only use case.For all day drivers (Uber, DealDash and cross country types) fueling time should include time off route to get to fueling facility which is longer for EV at the moment because of lower charge station density. I wouldn't try to assign a value, it depends heavily on route and location, but I am sure of the sign.I don't yet own an EV so don't know if every charging station has a fast internet connection so that billing is rapid. I know that this process varies greatly at gas stations, from perhaps fifteen seconds at stations which have upgraded to chip readers and have fast internet, up to times like you mention for remote locations with ancient pumps and 56kbaud connection speed.Pumping the gas takes a few minutes, a time I spend removing bugs from the windows everyplace but Oregon where I live. If you spend minutes topping off the tank it is a personal problem and you are ignoring the admonitions of the state of California who ask you not to do that to minimize vapor emissions and spills. (EVs also have a need for bug removal, and plenty of time to do it, though charging stations I have seen hide the wash bucket and squeegee pretty well).The only times I have had fifteen to twenty minute stops for fuel have been at Costco in big cities where there are often lines at the pumps. Fortunately I don't live there, so that isn't my use case either.

content: Quote from: DougSpindler on September 07, 2020, 11:37:03 pmI haven't timed it with a stop watch, but my experience in America is that it takes around 5 - 7 minutes to do a "pit stop" at my favourite gas station, usually 10 - 12 gallons. I use a gas station own-brand card at the pump, which gives me the cash price.Regarding the original post: The use case where fuel costs are the main part of the business is the best possible case for an EV. However, consider that most people don't drive their cars quite that much.Mathematically, if you are a low annual miles driver (or, if you own more than one car, so each car gets relatively less miles on it), the original cost of the vehicle matters much more than the fuel economy, since you simply don't use enough fuel for the savings of an EV to matter much in the overall picture.

content: Quote from: maginnovision on September 08, 2020, 03:36:24 pmI make a round trip drive about once a month -- 900 miles south, then back north again -- sometimes twice a month. Often I will drive non-stop (except for gas and food), and get from one end to the other in about 17 hours. I definitely eat in my car, usually packing a small cooler but sometimes making a *quick* stop at a drive-through.This 900-mile drive, mostly up and down US Interstate #5, is probably the main reason that I don't seriously consider getting an EV. I don't want to have to find a fast-charge station, and I really don't want to wait an extra half-hour to charge the battery.

content: Quote from: SilverSolder on September 08, 2020, 02:20:46 pmThanks for providing a data point closer to my claim.Looks like I'm mistaken on the fill-up/charge time with a Tesla super charger. I was repeating the 20 minute time someone in the forums posted a while back. Just looked up the times and it's 20 minutes for 50% charge and 45 mins for 80%. That sucks.There was a Tesla owner saying he could drive from San Francisco to LA and it took him only 20 mins to get super charged. I guess he left out the fact he was only getting a 50% charge.Having to wait 40 mins to get an 80% charge just doesn't compare to 5 minutes to fill a tank with 100% liquid hydro-carbon fuel.

content: QuoteFrom my experience, if not going to eat close by, my supercharging sessions are 15-25 min (SR+ on CCS V2 superchargers), because it often makes more sense to stop at 60-70% than to wait for 80 or 90%. At least with the parameters we have in Europe (lots of superchargers, colder temperatures)I also regularly arrive with 5% charge at a supercharger. No risk of arriving to 0, you can always slow down on the last kilometers if needed ( or stay behind a truck

content: Quote from: f4eru on September 08, 2020, 05:09:46 pmI'm confused. You have a Tesla, correct? When you need a charge doesn't it take 20 mins to get to 50% charge, and 40 mins to get to 80%? That's what I just found by Googling.

content: superchargers are getting faster those days.The SR+ can accept up to 150kW, for a 50 kW battery -> 20 min to charge full if there was no dropping off, so approx 10 min to 50% (but it's not yet that good in practice)Also, please note : SR+ was locked to 100kW until end of 2019 or so, so many curves yyou google are obsolete.

content: Today's figures for the SR+:5 -> 70 %: 18 min 48 s<- this is why I often stop at 70% if that fits my trip.5 -> 80 %: 24 min 42 s

content: https://insideevs.com/reviews/350883/tesla-model-s-review-450000-miles/Telsa made a warranty decision for publicity value, namely offering the 8-year infinite battery warranty, which Tesloop took advantage of to get multiple battery replacements as they wore them out in their high-use scenario. Tesla has now corrected that mistake. Newer production Teslas, including X, S, and model 3's, all have 8-yearmileage limitedwarranties, which throws some major avoided expenses back into future cost analysis.https://www.tesla.com/support/vehicle-warrantyRoad taxes -- yes, it's been a free ride there for EV's, but that is changing with new EV fees collected at registration in some states to replace lost revenue. Expect most of the other states to follow suit eventually. So far they seem to be flat fees, rather than mileage based ones, which could be a disincentive to low-mile drivers.https://www.foxbusiness.com/money/california-adds-electric-vehicle-fees-up-to-175That said, EV's are probably excellent choices for a lot of high-use situations, where the cost of fuel becomes an key part of the financial model. For the average consumer, that math doesn't work so well...the difference between the (cost of purchase - resale price) / years of ownership tends to override all other factors, including fuel.Me personally, I can't justify it. I simply don't do enough driving, even pre-covid, filling up every 4-5 weeks, plus one 1500 mile road trip per year. And during covid...I'm filling up about every 3 months.Pit stop time is a laughable measure. Highway mileage for a 2017 Dodge Grand Caravan is 28 mpg with a 20 gallon tank, which means about 500 miles (800 km) practical range. If I'm stopping for fuel, I really need a pit stop for bathroom and food as well...the time spent not driving is actually welcome at that point.

content: Quote from: Nusa on September 08, 2020, 07:42:40 pmThis is correct, but not the prior warranty did not cover degradation, only total failure of the pack.If Tesloop had their pack replaced it was likely because it was one of the early revision Model S/X packs that had high failure rates (something like 99% of all -A series packs and 70% of all -B series packs were replaced under warranty, old packs being refurbished.)In their defence Tesla were still figuring out how to make cars at that point ...

content: The replacement rate was significantly higher than 0 here in southern California. My source was(we're still friends but he doesn't work there so I can't say for sure but it's pretty likely nothing much changed) a tesla service manager before he moved over to rivian. He made the move this year. It was almost 4% while he was there(2016-2020).

content: Yes, it was pretty high initially. For one, Tesla had contactors failing in the battery pack, and in the initial pack version, it was not easy to service these without changing the whole pack.I guess the question is whether Model 3 and newer Model S have high pack failure rates. Does he still work for Tesla?FWIW, the battery pack in my PHEV was replaced under warranty as water had contaminated the pack. (Seal was not fitted correctly in the factory - known recall for VW electric vehicles.)
