    I seriously hope the next US administration stops bending over backwards to protect the big 3. If we want to address climate change, we're gonna low cost greentech and china is currently the king of that in evs, batteries and solar.

    If we're really so concerned about 'supply chain' issues we could build up a strategic reserve of batteries and solar panels. If china wants to continue subsidizing their industry below costs of manufacture I see no reason why we shouldn't exploit their generosity to meet our climate goals as quickly as possible.

    One of the 'good news' stories re: the recent datacenter buildout is that grid storage is now being more widely deployed, and that compliments the roll out of renewable energy.

      Hear, Hear. We are seriously missing out over here in the US and continuing to be protectionist over the big 3 automakers is not going to improve our climate situation.

      I consistently hear 2 main arguments against electric vehicles in the US. Range, and cost.

      BYD & China is solving both. Range is important because we lack charging infrastructure still, and anyone who rents at an apartment complex, you are screwed and have to rely on public charging stations. Big batteries are important for these folks. People also still have range anxiety, so when a fuel efficient gas car will get ~400+ miles per full tank, only having more expensive cars with a ~250 mile range is a non starter for a lot of people in the US.

      Cost is self explanatory. One of the better electric cars sold in the US, the Ioniq 6 STARTS at $38k, which is already more than a significant chunk of the population can afford - you're looking at close to an $800/month payment at current rates for entry level. BYD could sell in the US at around $20,000.

        Byd recently came out saying the hyper competitive landscape and low prices needs to end soon. The Chinese government is propping up a lot of their auto industry right now. So some protectionism is needed if you don’t want one of the last bits of manufacturing strength to disappear in the US.
        • Spivak 1 hour ago
          Genuine question, we have manufacturing strength in the US auto industry?

          Even among Americans, American cars aren't considered that good. There's a massive reliability premium you pay for Honda and Toyota. Even cars with 100k miles on them (frustratingly as a buyer) keep their value. And they're manufactured in the US, inasmuch as any car can be said to be manufactured in a single location.

          I've been searching around and I can't even find data about other countries importing our cars which to me would be the biggest signal of strength.

            Teslas are great cars.

            I've only been in BYDs in Mexican Ubers and I would not buy one, it felt cheap and plasticky and creaked.

            • bratsche 32 minutes ago
              I have a 2018 Model 3 and your description of BYD is exactly how I would describe my Tesla. It feels cheap and plasticky and it creaks. I also briefly had a Model 3 rental car that was newer than mine (but I don't know what year it was) and it also felt the same.
            • Spivak 27 minutes ago
              I had thought about throwing an exception for Tesla because they did manage to create cars that people outside the US want. So I guess that does count but I doubt they're what anyone thinks of when they think of American car makes.

              Oh I would for sure buy a BYD today if I were able. The ones I've ridden in have been really nice. I mean they are literally plastic but so is every car in the "economy" price range. I don't think their interiors were noticeably different than any other non-luxury car. I've been told that their higher end models don't have this problem.

        Not to say EV charging has been solved, it is still very much in progress, but 64% of Americans live within 2 miles of a public charging station. We should continue to use policy to encourage "EV ready" infra in residential and apartment settings, places of business, commercial/retail, government, etc, but lots of folks can be served today. The vast majority US housing stock is single family homes (attached and detached combined), and those can, in most cases, be upgraded to support a dedicated circuit for charging. And, to your point, you'll also want to mandate new apartment building build outs are EV charging ready for their tenants.

        https://www.pewresearch.org/data-labs/2024/05/23/electric-ve...

        Key takeaways from the above:

        > The number of EV charging stations has more than doubled since 2020. In December 2020, the Department of Energy reported that there were nearly 29,000 public charging stations nationwide. By February 2024, that number had increased to more than 61,000 stations. Over 95% of the American public now lives in a county that has at least one public EV charging station.

        > EV charging stations are most accessible to residents of urban areas: 60% of urban residents live less than a mile from the nearest public EV charger, compared with 41% of those in the suburbs and just 17% of rural Americans.

        • oivey 4 hours ago
          2 miles is an awfully long way, and 36% of Americans are even further away. That’s 4 miles round trip. Presumably many of those charging stations aren’t that big and disallow you leaving your car overnight. The rest of the numbers are similarly bad.
          • nothercastle 2 hours ago
            The chargers probably have 2/4 chargers working at any given time.
          • richardw 4 hours ago
            It’s not insane to hope many cars will be able to go and charge themselves at 2am, when roads are quiet and chargers are free, a few years from now. Optimise over the entire system, schedule it, car ready for the morning.
            • margalabargala 2 hours ago
              This is going to be a long time coming. Owners of EVs overwhelmingly live in houses not apartments. No one is going to send their car off to pay many times their home rate per kWh when they could get a home L2 charger and charge it themselves. It would pay for itself in under a year.
              • richardw 1 hour ago
                My comment is not solving for people who would be better served by charging at home, because they don’t care about the distance to a charger. Waymo’s can already find their own way to a charger, so it’s not a huge stretch to imagine people innovating around this problem for owned cars.
                • margalabargala 15 minutes ago
                  Waymo might build a waymo specific solution, but the general case for the general population won't exist for a long time.

                  The demand isn't there. The group of people who buy EVs and don't have a home to charge at is too small. And that won't change until the economics of purchasing an EV fundamentally change.

          • toomuchtodo 4 hours ago
            Doesn’t appear to be a problem for EV sales. Is your closest gas station 2 miles away?

          > 64% of Americans live within 2 miles of a public charging station.

          If this includes AC chargers, leaving your car for 8 hours 2 miles away is an absolute pain.

          If it doesn't, the question becomes are the chargers occupied? Are they operational?

          Waiting at a gas station takes a minute, waiting at a charger takes 30.

          I've been driving an EV for more than 5 years and pretending that charging isn't a significant hindrance to EV ownership is disingenuous. It's actually gotten worse because more EVs are on the road and the chargers haven't kept pace with the rising demand.

            > It's actually gotten worse because more EVs are on the road and the chargers haven't kept pace with the rising demand.

            It is curious that this is the case. If chargers were profitable a couple of years ago, you would expect more chargers and more profit today.

            I haven’t noticed much growth in chargers where I live but I have noticed more EVs on the road.

          • tass 3 hours ago
            I’m lucky to be able to charge quickly at home.

            I’m currently on a road trip and was leaving the car at a nearby charger which was walking distance from where I’m staying - I can’t imagine owning one where either this wasn’t available or there wasn’t a fast charger I could spend 10 minutes at.

            The actual long distance drives were super easy thanks to Superchargers - 5-10 minute stops keep you driving for hours! It doesn’t feel disadvantaged compared to gas so long as the infrastructure is there.

      • rconti 6 hours ago
        Hopefully this will allow cheaper cars to get ~400mi of range but I doubt we'll ever see much more in mainstream cars. Batteries are simply too expensive and too heavy. Fuel tanks are cheap to build, but we still see no gasoline passenger cars with large tanks. The manufacturers sort of standardize around a "normal" capacity, and just want the one option to design, manufacture, crash test, etc.
      • devilbunny 5 hours ago
        > ~400+ miles per full tank

        My car gets ~500 miles/800 km per tank. My wife's car, which has a more efficient engine and transmission and is also smaller, but with the same huge tank, gets ~600 miles/960 km per tank. I will have to stop for a bathroom somewhere along a route that long, but only once or twice. I used to have to stop three times for a ~900 mile/1500 km trip that I did a few times.

        This is a problem with EV proponents who try to argue that "you'll stop every couple of hours for half an hour or so anyway, so charging isn't an issue". No, I won't. I'll drive 1000 miles with less than 45 minutes of downtime on the whole trip. I don't stop every two hours. Maybe 15 minutes every 4 hours, of which 10 is fueling and going to the bathroom and 5 is getting off and back on the highway.

        That's not a slam against EV's, but let's acknowledge their weak points honestly.

        • bruce511 1 minute ago
          I hear you, and your concern is real for your context.

          But to be fair, not every product has to perfectly fit every context. To be successful a product can fill a small niche, or it can appeal to a large market- it doesn't have yo satisfy every use case.

          So you're right - driving 1000 miles with no downtime is not an EV strength. But the percentage of the market doing that is tiny. Conversely the proportion of people who live in a house (home charging) and drive < 100 miles a day, is huge.

          Even for those doing a "once a year road trip" - well, hire cars exist.

          So I completely agree that an EV is not useful to you. I would suggest though that a product can be massively successful, while at the same time appealing to a subset of the market. And appealing to a subset does not limit validity or indeed profitability.

          Lipstick seems to be a successful product, despite only appealing to something less than 50% of the market.

        • asadotzler 3 minutes ago
          Your 500 and 600 miles per fill-up is the kind of outlier that isn't much worth discussing. That kind of range can't be more than about 5-7% of US autos.

          My car (Mazda3 hatch) gets 24 mpg, which is actually typical for US mid-sized cars.

          I have a 3-5 minute gas station fill up every 260 miles or so, basically once a week. The Chinese MG4 does 435 miles on a charge, 95% of which I could charge at home, the remaining 5% of my miles are my twice a year road trips @ ~400 mi (to LA) and ~800 mi (to Seattle).

          The MG4 makes LA without a stop and Seattle with 1 stop.

          That's a once a year stop for ~30 minute in the EV compared to 3-4 hours a year sitting at smelly gas stations for my Mazda ICE.

          I would certainly trade never having to ever take my car into a gas station, ever again, for one brief stop once a year on my leisurely road trip if I had the cash to buy a great EV.

        • dcow 3 hours ago
          I think the argument is not whether EVs will take an extra 65-80 min to go 1000 miles, it’s whether that matters to the average driver. Realistically for my family it doesn’t. I’m sure for some (predominately) solo drivers it does. But then there’s the question of how often you’re driving 1000 mile trips that an extra 1.5hrs max actually impacts anything real in your life…

          I guess if you’re trying to follow an ICE car on a road trip then yeah it might be a weak point. If you’re already stopping every 200 miles then it’s no matter. For us, we enjoy travel days more with the built in stretch/bathroom breaks.

          • bryanlarsen 41 minutes ago
            You can do 1000 miles in one day, but it is a really unpleasant trip. Doing it in two is so much nicer. Take a hotel one night. Have a really nice meal at a slow restaurant a couple of times. Visit a couple of roadside attractions.

            Those are five long charging opportunities, which is two more than you need for a 1000 mile trip.

        • justinrubek 1 hour ago
          That sounds like you have a more efficient car than many of us. When I switched to an EV I actually got a range upgrade due to having a really inefficient ICE vehicle. Regardless, most of us aren't spending our days doing multi hundred mile drives. We shouldn't be optimizing for that scenario.

          I'd like to see the stats on how many people regularly drive 500+ miles in a day.

          Agreed but this car would solve that for just $25,000 if we didn’t have 100% tariffs on Chinese vehicles. 1,200 mile range, can charge 800 miles in 12 minutes.

        Not only the climate situation, the economic situation. If the US protects the old tech for another decade it’ll never catch up. The US needs to move along the experience curve as fast as possible, build skills and volume and charging stations and suitable power grids and sources. I would much, much rather be China than the US in this fight right now.

            A key problem is that anger, hate, and fear are more powerful motivators than hope and optimism. That fact has been leveraged to weaponize those emotions to a degree that inspires awe at it's success.

            Freedom to power your home without paying "the man" should be compelling to all who could use it. Texas is ironically a prime state for renewable energy and the dollars generated from it have convinced some, but many still reject it as "wokeness".

      > If china wants to continue subsidizing their industry below costs of manufacture I see no reason why we shouldn't exploit their generosity

      Because the unfair advantage distorts the market leading to a potentially otherwise noncompetitive product destroying the competition at which point they can (and will) jack up prices, so not only do you get more expensive vehicles, but you've also destroyed an entire industry and several adjacent industries at the same time.

      It's not like you can't just snap your fingers and re-establish a vehicle manufacturing supply chain once it disappears.

      I get people just want cheap vehicles, but the short-term benefit simply isn't worth it.

    Most relevant part:

    > BYD’s solid-state EV batteries set a record by gaining 1,500 km (932 miles) range in just 12 minutes of charging.

    > The test charged the battery to just 80%, meaning total EV range could reach upwards of 1,875 km (1,165 miles). Keep in mind, that is CLTC range. On the EPA scale, it would be closer to 1,300 km (808 miles)

    Is this true? How quickly will other companies be making these types of batteries?

    Is there some reason why solid state batteries seem to be being deployed in cars sooner than in phones?

    • MostlyStable 7 hours ago
      For the last part, my guess is that the advantages are much more valuable in an EV than they are in a phone (where batteries are mostly fine. While longer life and faster charging are always nice to have:they are just that: nice to have), so if you are A) production limited and B) they are still more expensive (the article states they expect them to be price-comparable by the end of the decade), then they probably aren't worth it in a phone (yet).

      When price comes down and production comes up (assuming those things happen), then I would expect them to start appearing in phones as well.

      • Dylan16807 6 hours ago
        That logic seems crazy to me. Extra hundreds of miles are also just nice to have, and with the same material that goes into a 500kg car pack you could make 10000 double life phone batteries and sell them for $100 each. There's more per-cell overhead in the phone batteries but is it worth a million dollar drop in revenue?

Gotta visit Dad on the farm a dozen times a year or whatever? That’s not your life so you don’t see it as essential even if the rest of the driving is much shorter range.

            To fix iPhone battery life, create an automation that turns on battery save mode when battery dips below 80%. Works really well. I figure they don’t build this functionality into the settings because people would use it instead of buying a new phone when the battery degrades.
          • Dylan16807 33 minutes ago
            It's obviously more valuable to double the range of a car compared to a phone.

            But is it multiple thousands of times more valuable? I don't think so.

          • nicoburns 4 hours ago
            It really should work with a car (there's no reason why they couldn't support additional external battery packs in the trunk or as a trailer, etc).
            • margalabargala 19 minutes ago
              The reason is that batteries are heavy.

              Want an extra 100 miles of range? That's 600lbs of cargo. A person can't place that in a trunk, and a trailer would probably barely extend range due to the extra drag and efficiency loss.

        • MostlyStable 6 hours ago
          Consumers seem to disagree with you on the first part. I personally think that current battery tech is fine for EVs (I have an EV with a 260 mile range, and only a 77kW max charge rate, and I think it's fine even for 10+ hour road trips), but a segment of the consumer space wants more than that.

          I personally thought that the more interesting part of the article was where they claimed to be able to add 800 miles of range in 12 minutes. At those kinds of charge rates, my ideal EV would probably have a 300ish mile range that I could charge from 10-80 in <10 minutes (although I believe that part of the way they get those charge rates is with large battery packs, so a smaller pack would probably not charge as fast).

          Additionally, while the specs for EV sedans are currently fine, batteries are only barely good enough for larger, less efficient vehicles. Maybe the killer app here isn't a sedan that goes 1000 miles, but a truck or SUV that can go 500.

          The point is, whatever your and my opinions on the adequacy of current EV charging, the market seems to value improved battery specs more highly in the EV space than it does in the phone space (or maybe it doesn't and BYD is making a mistake by keeping their batteries for their cars instead of selling them to phone manufacturers).

          • actsasbuffoon 5 hours ago
            EV batteries degrade more quickly when charged too far above half-way. As a result, your ideal EV might actually have 600 miles of range and you’d just leave it half-charged most of the time.
            • MostlyStable 4 hours ago
              From everything I've heard/read you can pretty safely go to 80-90% of listed state of charge (manufacturers often also include a hidden buffer for exactly this reason).

              My car, which like I said has a 260 mile range, I only charge to 80% unless I'm going on a long road trip. So for 90%+ of the time, it's never charged more than 80% (and I very rarely discharge it to less than 15%). For most people, a 300 mile range like I describe would be plenty to be able to not need 100% charge except on rare occasions. But even if it's not for you, or for some people, I very specifically said "my ideal EV". A 600 mile range that I almost never use is just extra weight that I'm carrying around and decreasing efficiency, and isn't actually providing much real battery protection. I am absolutely not someone who drives 360 miles a day (which is what you could do if you were doing an 80% to 20% discharge on a 600 mile battery every day. I'm pretty confident that stats suggest that very few people drive that much on a regular basis. The 150 miles I get from the the 80% to 20% range on my current battery is already more than enough.

        Battery life is fine but phone company are always after thinner and lighter. I can’t imagine no company will jump on this.

        Just look at rumored iphone air

        • harry8 4 hours ago
          I’d take a phone double the thickness to get double the battery life between charges. Options on that front are limited. Had an ulefone for a while which was better than most until the screen started getting constant phantom presses making it unusable.
          • ggm-at-algebras 28 minutes ago
            My hand does not shrink. Try holding and using a phone as thick as a credit card compared to one 5mm thick and ask yourself which feels better.

            Ie, I agree totally with your sentiment

      > Is there some reason why solid state batteries seem to be being deployed in cars sooner than in phones?

      Not quite energy density, but the energy density, cost, complexity when combined with the discharge profile generates a very "interesting" phase space.

      There's a few promising technologies which have very, very good efficiencies but only like very slow predictable discharge cycles. These are excellent for say building giant GW batteries in the desert, but not so great for even car batteries.

      Phones and tech have bursty power needs based on use, the cost of taking other tech down to the size of a phone is extremely high (especially if you're first to market unless you know you will sell millions of units). Not to mention the reliability of batteries typically decreasing as the size drops.

      Cars tend to be in the middle with their discharge profiles being relatively smooth compared to say a laptop, but yes you still have economies of scale, complexity, reliability and supply chain and patents to contend with ;)

      • awongh 6 hours ago
        I guess I would have just assumed that because batteries are chemistry the size scales relatively easily.

        Anyways- isn't a normal cell in an EV battery is like a AA size? Is this still true for solid state?

        • vel0city 1 hour ago
          > isn't a normal cell in an EV battery is like a AA size?

          No. Some companies use tons of cylindrical cells that are larger AAs (like 18mmx65mm, 21mmx80mm, or 46mmx80mm). But even then at 46mm in diameter it's a good bit bigger than a AA.

          But lots of manufacturers use prismatic or pouch like batteries. They're large and rectangular. Like these batteries on this BYD, they're called "blades". Most other major manufacturers use prismatic cells.

      They already exist in Chinese phones, the new one plus has insane battery life because of its 6000mah battery, while still being as thin as a normal phone.

      The tech used to get such fast charging isn't revolutionary, it's just extremely (dangerous) high voltage DC charging that only exists in any capacity in China.

      Also, what happens when an EV taxi runs out of battery power in China? They actually have stations setup all over that you simply drive into and it replaces the entire battery pack... in minutes.

        Really no more dangerous than a 480v, 300A level 3 charger in the US. Both have enough to kill. It's not like you'd be less dead if a level 3 charger malfunctioned. They both require redundant monitoring hardware and female plugs on the hot end.

    would be very interested to know if people know what the cold-weather behavior of these batteries are: i'm in montana and battery life, especially in winter, can be a life-or-death issue and that (+ range/recharge time) is a reason a lot of folks here look at ev's skeptically, would love to hear they handle cold better
    • ggreer 6 hours ago
      I think people are working off of outdated information. I have a 2020 Model 3 and it's been fine in subzero temperatures. Yes, range goes down by about 20%, but if anything it's more convenient than a gas car in the cold because you don't have to wait for an engine to heat up before the cabin gets warm. Also you always wake up with a full tank (so to speak) because you don't need to go to a gas station to refill. And EVs tend to be AWD, so they're easy to drive in the winter. During one snowstorm I had to help dig out trucks that got stuck, but my car was fine.

      Newer models have heat pumps that greatly improve efficiency in cold weather. They also have better battery chemistries that store more energy in the same form factor. Unless you live in a very remote, very cold location (eg: rural Alaska), an EV is a fine choice.

            Montana is colder than Norway in the winter. Norway gets a lot of warming from the coasts. There's not much coastline in Montana. It gets hit pretty hard by polar winds without the mediation of the oceans.

            Turns out there's more to climate than just latitude. Lots of the US is colder than Western Europe on average despite mostly being far further South. NYC is colder than London in the winter even though it's coastal and a much lower latitude.

      How far are you driving in a typical day?

      If it’s less than like 100 miles (161km) I think that the vast majority of EV batteries are going to get you where you want to go, even with 25% reductions due to cold weather. FWIW, the American average is around 36 miles/day.

      There is a semi famous YouTuber named Hank Green that lives in Montana and daily drives an EV. He occasionally makes videos about his experience.

    • Marsymars 5 hours ago
      IMO “handle cold better” is a bit of a misnomer for EVs. ICE cars are inefficient all the time because they’re converting most of their energy into heat even when it’s warm - with an EV you’re effectively just getting bonus range when it’s warm.

      If you developed a hyper-efficient ICE engine that didn’t generate a pile of waste heat, you’d have to actively make it less efficient in the cold, or install heating hardware and burn extra gas to power that hardware - but nobody would criticize that hyper-efficient engine for being “worse in the cold”.

    • bryanlarsen 7 hours ago
      > and battery life, especially in winter, can be a life-or-death issue

      How so? A full battery can run your seat heaters for about a month. That's a lot better than the hours of heat you'd get out of a full tank of gasoline.

      Not to mention that you'll never get carbon monoxide poisoning from a gasoline engine with a tailpipe blocked with snow.

      • Zee2 5 hours ago
        I believe they are talking about how the range/capacity is significantly affected in deep cold weather. It's not about life-or-death that you'll freeze to death - it's that your 300mi EV turns into a 150mi EV and that makes range planning unpredictable and more challenging in rural areas.

          Is it road-accessible? What kinds of vehicles can get there?

          The cars in the article have twice as much range as a gas car or more, even in the cold. And it's easier to charge them at remote locations than to get fuel deliveries to those same remote locations.

          I'm sure a scenario could be contrived where any type of car wins, but on average I expect a long range battery car to do quite well.

            -40ish for a month. And -30 around that.

            None of the ‘answers’ address the range issues with batteries in the cold. Or how you can be totally fucked if your pack drops below a certain temp, and you don’t have enough charge to heat the pack and get home.

            Probably even more fucked than if your diesel tank gelled. At least you can heat it up directly if you really need to.

            • bryanlarsen 21 minutes ago
              You handle it the exact same way you do on a gasoline vehicle. You never let your tank go below 50%. If you slide off the road with a low tank or a low battery you can get in trouble, so don't do that.

              If I let my electric car sit overnight with at least 20% charge, I know it will start in the morning, even if it was -45 overnight. You can't say that with a gasoline vehicle. It'll take almost all of that 20% to get up to temperature, but once it's up it maintains it well.

              And anyplace cold has ubiquitous block heater plugs. At really cold temperatures it'll barely charge on a block heater plug because it'll use all the energy keeping the battery warm, but it means you start with a warm battery and a warm car, so the range drop is massively reduced.

    The resistance to electrification in the US is one of the country's biggest self inflicted wounds.

    In the long run, I really don't think we can tariff our way around technical innovation.

    900 miles of range in 12 mins of charging... Charge for 20 mins and have enough range for 2 full days of travel driving!

    And this is only when driving long distances. Anyone with a driveway can eassily charge overnight for typical daily driving.

    The whole package: many types of energy source providing electricity, never having to go to a gas station for typical daily driving, path to complete elimination of petro combustion byproducts, massive simplification of the overall vehicle mechanism, significant performance enhancements, etc.

    All technical evaluation come out in favor of EVs...
