  I have an EV and so does my wife, we road trip all the time, the biggest issue is recharging times. Sitting 30 mins for a charge is fine every couple hours, but those level 2 chargers and slow DC chargers just kill all momentum on a road trip. Electrify America has decent chargers, and the most up to date ones work better than the last generation, but neither car can take their top speed charging, if they did it would be a much better experience.

    Well, a lot of the chargers also can’t charge the ioniq5 and the like at their full rates. So that is indeed a mess. But it is also the kind of mess that gets resolved over time as there is a bigger emphasis on “plug in while you go shopping” rather than dedicated locations.

    Which gets back to the fundamental disconnect. People think of it in terms of going to a gas station and staring at the display while you debate if it is worth getting back in your car. When it really should be about 5-20 minutes here and 5-20 minutes there.

    Its still going to be a disruption relative to stopping for gas and then flooring it for another 8 hours. But… my ass is old and that is a good recipe to have massive blood clots in my legs. Similarly, friends who can put up with children will always be on the lookout for a playground or a sit down restaurant. And, in terms of range, stuff like the ioniq5 and subaru soltera are more or less in that sweet spot of “stop at lunch, charge up, stop at a hotel and then get dinner at your destination” model. Combine that with 5 minutes here or there to increase margins and take a piss and it really isn’t that different than a road trip for people who don’t still think they are in their early 20s and trying to go 800 miles on a weekend trip.

      Just based on build quality and reputation, I’d take a Subaru Solterra over even the highest-end Tesla any day. I live in Minnesota, and my bigger concern about Teslas is the lack of ground clearance. If I can get out of the snow bank in the ditch, I don’t need my car’s heating system to last 12 hours.

      source

      • NuXCOM_90Percent@lemmy.zip ⁨11⁩ ⁨months⁩ ago

        Would strongly suggest NOT buying a '23 Solterra. For some unfathomable reason, Subaru decided that you don’t need a rear windshield wiper. Which means you are completely blind if you are driving on a mountain row in the snow/slush and so forth. ioniq5 has the same problem.

        But yeah. You have solid build quality and a frame that is heavily based on tried and true designs. Versus something where the build quality is so bad that you need to be careful if it rains…

    You will not have that problem with Tesla though. All chargers are 150kW+.

      Not true. V1 superchargers are 75kW.

      • tmRgwnM9b87eJUPq@lemmy.world ⁨11⁩ ⁨months⁩ ago

        Yeah right, and they are a big problem. I haven’t encountered a single V1 super charger in Europe after 4 years.

        I have only ever seen one in the US and it was surrounded by V2 and V3.

      That’s not true, there are level 1 and level 2 chargers for Tesla on top of the DC chargers.

  It’s more than weather. I don’t believe it’s possible to achieve the advertised range on any public road in any weather. I can drive like an old lady and I’m nowhere close. Driving normally typically results in at least 75 miles below advertised range and I live in a warm place.

  That said, the range hasn’t been a problem. I always have enough range. It’s not really something consumers need to worry about because you can drive like you stole the car and still have plenty of juice to get to the next Supercharger.

  However, it is a problem that the stated range is so far off the mark. You sort of expect it to be off in every car under normal driving but possible if you drive in a way to extend range. That’s not the case with Tesla. Their range estimates are entirely misleading like so many other things with the car.

  Honestly, I strongly feel that charging time is an important metric if you’re trying to displace ICE vehicles. Range, as long as you’re somewhere around 200-300 miles, is fine. On the highway my 4Runner gets about 300 a tank, my TLX gets about 500. In either case I’m lucky to go 180-200 before either someone has to pee, it’s lunch time, or I’m just tired and need to stretch. If I can charge up in ~15 min, while we’re all eating, stretching, using the restroom, etc, that’s perfectly acceptable and would easily replace my ICE vehicles. If it’s going to take an hour or more that really kills any sort of road trip. Especially around holidays when the chargers are going to be slammed. Think about the amount of pumps the average gas station has now and then realize that you’re talking 5x for 25min, if it’s an hour, 10+ times as long a stay at each one. That really changes the way we move in the US.

  Sure day to day, this won’t matter. I’ll top off over night and be good to go for my commute. But no one’s going to buy one EV and one ICE/hybrid just to be able to visit family. They are WAY too expensive for that, and unfortunately, We don’t have the train/airline infrastructure here in the US for not doing that.

    Thats just getting the charging network sorted as I can already charge my EV from 20 to 80% (or about 47kwh) in about 18 minutes at the right charger and faster charging EVs are already coming. My car doesn’t even have battery pre conditioning that would improve things further.

    Charging to 100% on stops on a road trip is always a bad idea, you are always going to need A LOT longer to get that last 20% or so than the 60% of charge from 20 to 80% due to the way current batteries work.

    It is almost always quicker on an ultra fast charger to charge twice to 80% than once to 100% and you get significantly more range doing so. Charging twice to 80% nets me 94kwh and charging once to 100% from 20% nets me 61.6kwh, and the former is usually minutes faster to do as well.

  • Pasta4u@lemmy.world ⁨11⁩ ⁨months⁩ ago

    Yea, 300-400 miles would be okay imo. However it takes me five minutes to fill my Gass tank and in that time everyone could go and pee and we can be on the road again. Roght now it’s like 40 minutes for am 80% charge on these cars. Also every few miles there is a gas station. Who knows how long inhale to drove to get to a charger.

    I think instead of ev tax credits that largely benefit the wealthy they should have spent that rebate money rolling out rv charging stations. To be honest I think we need at least a 2:1 ratio of ev chargers to current gas pumps and more likely a 4-1 ratio for this stuff to really take oft.

    Big batteries don’t charge faster than small ones due to both being different amounts of smaller batteries, at the same time installing quick charging capabilities in domestic garages is complete overkill, over night is perfectly adequate.

    There’s probably going to be a mix of services: Quick charge ones which just might be done before you’re done peeing and looking at sandwiches, where the operator wants you out of the booth as quick as possible so another can come in, and more relaxed road side diner like situations where an hour is perfectly acceptable (well, at least from an European POV), but there’s also going to be as many chargers as parking spots.

  I’m not sure whether to vehemently agree or strongly disagree - this is all over the place

  But

  • yes, PHEVs were a fantastic step to reduce global warming … decades ago. The biggest issue with PHEVs was they were never widely produced and sold. Now that technology has caught up with a better choice, it’s too late to turn around and say “we’ll do what we should have 15 years ago”.

  • my ICE car can go 340 miles on a tank of gas, supposedly, however I typically get 280. Have I sued? No, I understand it’s affected by weather, by the impossibility of creating a perfect standard behavior, and my lead foot. The manufacturer of course wants their product to look its best, so has an incentive to stretch that as far as they legally can

    Wait what? The fuel efficiency is based on the 5 cycle fuel economy test, which includes a mix of highway and city driving. IIRC the figures from EPA/CARB are less rosy than EU/WLTP.

    Tesla is definitely the odd one out here. Most manufacturers you can meet or exceed if you try hard enough. When you look at legislation, they say to use good engineering practice. Tesla arguably is not in this case.

    I’m not sure if the the BEV/PEV regulations were solidified when Teslas first came to market, but they sure as hell are now.

        As much as I like car and driver, that article is absolute dog shit. The edmunds article is interesting though.

        I bet your gripe isn’t with the EPA, but with SAE. I may be wrong, but if I recall correctly SAE uses EPA tests to define J1634 and allows manufacturers to either run an SCT or an MCT. EPA then adopts that into legislation. I believe EU/WLTP also uses J1634 but substitutes the EPA test cycles with the appropriate WLTC cycle (usually 3b for vehicles you would find in the US).

  It’s more than weather. I drive a non-Tesla PHEV and it achieves about 60% of the claimed range when I drive highway speeds like 60mph.

  The weather is a factor though. How will EVs ever be viable in freezing temperatures? The batteries will just shut down.

  • NuXCOM_90Percent@lemmy.zip ⁨11⁩ ⁨months⁩ ago

    Wind makes for significant impacts, even on good cars. Let alone cars built so shittily that they shake apart on highways and leak when it rains.

    The MPG ratings for ICE vehicles are a god damned mess on their own. There are lots of write ups out there but it is worth looking up the “golf ball car” video from Mythbusters (or just interviews with Adam Savage on Norm and Will Smith’s Tested). Your mood generally makes for massive variance. It is just that people tend to not really focus as much on a car they refuel once a week or once a month.

    But, because of regulations, those are still incredibly valuable numbers. Maybe you aren’t getting 40 MPG city. but you ARE getting “about 33% better” fuel economy than a car with 30 MPG city.

    Whereas tesla kind of just fucks around and then relies on gaslighting, fraud, and cultists. As is their way

    The batteries prioritize keeping themselves warm. I’ve driven my Tesla down to -40. The range is decreased and phantom drain is increased, but it always starts at the end of the day, even when ICE cars all over my work parking lot don’t. I suppose it could be an issue for someone who isn’t mindful of the charge levels or who doesn’t have access to daily charging.

    You probably have to use a portion of that energy to manage optimal thermal range.

    source
• abhibeckert@lemmy.world ⁨11⁩ ⁨months⁩ ago

  Because a lot of the exageration can be attributed to weather. You are going to have shorter range in the winter.

  I don’t really buy that. We don’t (well, most people don’t) drive around in freezing cold cars. The cares are heated and it doesn’t use much energy. Also if your EV is plugged in overnight it should be pre-heated to a sensible temperature (still cold, but not freezing).

  Combustion engines also struggle in cold weather - that’s why the cooling system is disconnected until the engine reaches operating temperature. EVs should be the same.

  And they can be - some brands only lose 3% of their range in cold weather. The shitty brands lose up to 35%… that’s not the technology’s fault, it’s a failure by the engineering team and consumers should be entitled to a refund if it was sold in a cold climate with only the summer range advertised. The car isn’t fit for purpose.

    You might “buy” more things if you actually continue reading rather than instantly feeling the need to stop and respond to a post?

    But to address a few of your expansions on what I said immediately after you just HAD TO CORRECT SOMEONE!!!

    • People don’t drive around in freezing cold cars: It matters less what the temperature in the cabin is and more what the temperature on the battery itself is. Most designs try to consolidate both to a degree but, for safety and insulation reasons, you are going to have a difference
    • Cars are heated and it doesn’t use much energy: That is only if you have a heat pump rather than resistive heating. Most of the mid/upper tier (e.g. ioniq5) provide these, but not all do. And, if it is snowing and raining hard, you will start to run into the limitations of a heat pump. At which point you are either SOL or back to resistive heating
    • If your EV is plugged in overnight: That is one of the ongoing issues with EVs where the vast majority of apartment complexes and hotels don’t have chargers
    • EV batteries and motors generate heat when they are running: To nowhere near the same degree as a combustion engine

    And then you just reiterated exactly what I said after you cut off the quote, regarding different brands and models having different behavior.

    source

    • abhibeckert@lemmy.world ⁨11⁩ ⁨months⁩ ago

      It matters less what the temperature in the cabin is and more what the temperature on the battery itself is.

      If the cabin is warm and the battery is cold, somehow exchange heat between the two. Not hard.

      That is only if you have a heat pump rather than resistive heating

      Every car has a heat pump - it’s more commonly called air conditioning, but it’s the same thing. And while some are only capable of cooling the ones that can do both cooling and heating cost basically the same to manufacture.

      Cars don’t use resistive heating - they commonly draw on heat from the combustion engine… in an EV that doesn’t generate enough heat (unless you’re on a race track) so you’d use a heat pump. Simples.

      the vast majority of apartment complexes and hotels don’t have chargers

      That’s relatively easy to fix though. Chargers don’t cost much to install, get it done in your own home (even if it’s just 110v - more than enough to keep the batteries warm) and you should be able to find hotels that have them (though seriously, how often are you staying in hotels and driving your own car? that’s a bit of a niche…)

      And then you just reiterated exactly what I said after you cut off the quote

      I read the rest of your comment. I agree with the facts you wrote but what I don’t agree with is your interpretation of them. A car that has 35% less than the advertised range for several months of the year does not meet customer expectations and should be either fixed with a recall or customers given a refund.

        All telsa had to do is complie with current standards which is to list highway and local mpg equivalent.

        Chevy doesn’t list a cold range when I need to idle the engine to get it warm enough to drive on a standard car.

  And like most of the tesla mess, this is just going to hurt EVs in the long run.

  I mean Tesla is pretty much the only manufacturer pushing EVs forward, so there’s some wiggle room there…

  Because a lot of the exageration can be attributed to weather.

  Weather is accounted for in standardized testing. Teslas also come with heat pumps unlike virtually everyone else, so they’re winter range will be much better.

  And tesla marketing basically made everyone terrified of their range

  [Citation needed]

  And you also need the fastest possible charging because you need to charge up your entire battery in one go and need to sit in your car while you do it.

  People don’t want to sit at a charger for an hour waiting for their car to charge on a 15 hour drive. Tesla did not create that demand, people did.

  PHEVs are neat but they are not better than EVs.

  In a less shitty and less musk infested world

  And once again it becomes clear that people like you are just shitting on Tesla because they hate Musk.

  There are plenty of reasons to hate Tesla without fabricating nonsense.
