Comment on Samsung delivers 600-mile solid-state EV battery as it teases 9-minute charging and 20-year lifespan tech

  You joke but I literally pictured a super long battery for a solid bit before it clicked. I was thinking maybe it was coiled and technically really long like a spool of wire

    Technically …… assuming cylindrical, it’s a long strip of metal rolled up. Not that long though

  It’s such a dumb metric for batteries. I wish people would stop using it.

  • KairuByte@lemmy.dbzer0.com ⁨1⁩ ⁨month⁩ ago

    Eh, it’s really not that dumb assuming there’s an average electric discharge for electric vehicles. Most laypeople don’t understand kWh beyond “bigger number better”.

    Miles

    Metric

    Pick one 😂

      Metric = a measurement, not the metric system.

        Makes sense

    I mean its a more a metric for the over vehicle. It can move its self that distance on a charge.

    The battery would kWh but that alone is insufficient for evaluating the vehicle

      kWh/Kg is really all that matters, maybe max charge discharge rates too.

      But they aren’t clickbatey enough for commercial news.

      source

      • fruitycoder@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

        But kWh/kg doesn’t account for additional energy sinks or drive train efficiency

  • conciselyverbose@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

    It’s what people care about.

    An EV that can only travel 300 miles on a charge is a complete nonstarter for me. It’s simply not enough for trips I take with regularity.

    • AA5B@lemmy.world ⁨1⁩ ⁨month⁩ ago

      But it it’s stupid because it doesn’t really relate to anything. Different cars have different ranges with different sized batteries and different efficiencies, at different weights and different volumes, so I have no idea what it means.

      Wouldn’t it be both more straightforward and more meaningful to phrase it like: x% more power for the same weight as current LfPO used in Tesla standard range

      Most importantly, batteries will always be expensive, so most manufacturers will prefer fewer/smaller for a cheaper and lighter car of similar range. Aside from trucks, I don’t see why we’d ever see many 600mile range EVs, especially if we get truly fast charging

      • conciselyverbose@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

        But people don’t care about that. They care “how far can x car go with it”.

        I will never even consider buying an EV that can’t go a minimum of 500 miles on a charge. I’m not willing to have short weekend trips held hostage by the availability of charging stations. That’s a very short round trip.

      How about the 2024 Ford Escape PHEV. 37 mile range on electric, which will cover most of dialysis driving, and then it switches to gas. Should work out that you can pay 1/3 cost for fuel most percent of your driving, and not have to worry about long range trips. Base price is like 41k, meaning a used vehicle would drop quick.

      • w2tpmf@lemmy.world ⁨1⁩ ⁨month⁩ ago

        I really don’t get why PHEV never ramped up to be the next thing instead of all this push to go full electric when the tech and infrastructure isn’t good enough yet.

        I think the complaint is most people don’t bother using the ‘P’ so it turns into an ICE with extra steps

        I’m still rocking my second generation Chevy Volt! 50ish miles on a full charge (if you live someplace flat) then 30-40 MPG after that, and it’s a reasonably sized hatchback and not an annoyingly large crossover or SUV. I would upgrade to a Bolt but god that car is ugly.

        I have an older fusion energi and don’t plug it in because charging every day is a hassle.

        I’m not anti-anything though. Clean energy is good, efficiency is good, the luggage space wasted isn’t awesome but whatever. I’m just explaining why I care about range. That’s not a long weekend camping trip and the infrastructure for pure battery in the places I like to be don’t make low range viable.

      How so, I’m curious? Do you drive into no mans land hundreds of miles away from civilization or are you a robot that never needs to take a break?

      source

      • conciselyverbose@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

        That’s a 3 hour drive into the mountains, and running out before I get back. It’s not a long trip.

        But, yes, stopping on a road trip is also a massive issue, and turning a 5 minute stop once a day into 20 3 times a day (on the limited routes where there are charging options) on an actual long trip would also be a dealbreaker by itself.

      Even with a 10-15 mins recharge? A couple of times a year I do make a 500 mile journey and if there wasn’t a sea in the way I would happily do it all in one sitting. But as a teeny tiny compromise I wouldn’t mind stopping to charge once or twice along the way! It would add about 20 mins to the journey sure, but seems like it’s worth the benefits to me.

        I don’t think you would get to the charger in 20 minutes. Assume there will be line.

        I don’t go places where recharging is an option.

        The long trips are ones where I’d be turning one 5 minute stop into at least an hour of stops per day. That’s not a small compromise any more.

    Want a stupid metric? How about miles per gallon

  • Rinox@feddit.it ⁨1⁩ ⁨month⁩ ago

    It’s not stupid if it takes hours instead of minutes to charge up. If this tech really delivers, then I’ll be more than ok with a 200 miles battery that charges in 3 minutes.
