Japanese firm believes it could make a solid-state battery with a range of 745 miles that charges in 10 minutes

  • Yes. Because you can literally sleep the other two hours your other shift is driving. We do it regularly.

    It is still not the same thing as taking a break. Some people can’t sleep in cars, most people don’t sleep well in cars. I’m glad you can. Just because you can does not mean most people can

    That’s unfortunate for you. Every single person I know does fine rotating drivers. Semis also do it all the time and it’s considered safe enough.

    Semis literally have beds in them. That is not the same as sleeping in a car

    Unfortunately not because the primary energy losses come from aerodynamics not from the climb. So you can recover a decent amount, and the slower you go the more you can theoretically approach 99% recovery, but in practice this is not the case.

    EVs take into account a ton of aero, and the aerodynamics don’t change going up or down hill. Also, in practice, regeneration going downhill does recuperate the range loss from going uphill. I have done it many, many times. Sometimes you even overcome range loss and end up with more than when you started if the descent is particularly steep, though that is much more rare.

    🎶safety factors🎶

    You keep saying safety factors, but it seems to be based on just a hunch

    it was a comment on having to use alternate routes to stay charged, not on the actual duration of charging, which can potentially add up is still only around 20% added trip time.

    That certainly can be a factor based on infrastructure. Again, we need a lot more out there

    I appreciate the thought but we have an EV in the family, most of what I’ve said here relates to safety and practical outcomes and considerations we’ve made and worst case scenarios. In other words we have already done road tripping ourselves.

    So do you have an EV or do you have family from out of town that does? You’ve kinda said both. Also, you have said you don’t want individual car arguments, but you seem to be basing everything on an individual car (the one in your family). The reality is the make/model of the car does make a difference, but it is becoming less and less of an issue as EV tech progresses, and a majority of them don’t have the issues you are concerned about. Unless you are road tripping in a gen 1 Leaf or Chevy Bolt, the concerns are more anxiety than anything.

    My partner and I go camping a bunch (no charging stations in the bushes), road trip from Seattle down to Oregon quite a bit. Like I said, we have also done very long road trips, but those are more rare (as they are with most people). We have never run into an issue where the extra time was an issue, have never lost 40% range in the cold (with 3 different EVs), and have never had an issue with hills or mountains (again, we have always gone down the other side or back down the same way in the case of camping). Hell, we live in Seattle which is a steep city and my partner drives for work (75-100 miles/day) and have not run into these issues. I will say we are lucky to live on the west coast where the infrastructure is much better than other areas, but I have always agreed we need more infrastructure. Even so, now that we have a place to charge at night, we don’t use much of the local infrastructure (which is a privilege, I know).

    More important than stuff we’ve been discussing (IMO, since most folks don’t actually road trip that much), I think more important things to argue for are infrastructure in rural areas, and infrastructure for people in apartments. Right now, not having a place to charge at night is a big barrier for most people in apartments. In rural areas, the distance between chargers is currently too high, though if folks have a place to charge at home, that is less of an issue for daily use.

      K. Different people have different experiences. Given I was responding to someone’s assumption that cars only transfer 1 person at a time over long distances, I’m going to say my response was pretty safely addressing this exact point. Feel free to disagree.

      True, and from personal experience the cars were more comfortable. Sleeper cabs are not that big.

      You keep saying safety factors, but it seems to be based on just a hunch

      See my other response.

      You’ve kinda said both

      Given one was explicit and the other is your inference this has been covered.

      you seem to be basing everything on an individual car

      Right, because I’m offering conservative estimates on the details using it to counter an anecdotal belief to point out that it’s not exactly as simple as the op was commenting on. This discussion is so far removed and so terminally reddit, christ.

      Seattle down to Oregon

      Something that is likely happening here is your definition of cold weather is not my definition of cold weather. Even the link I sent, which approaches 30%, barely touches below 20F. This is cold, sure, but not the most cold. Which when you are planning driving, you generally want to be able to drive in the worst conditions for your area so you don’t, you know, get stranded and/or die. Given temperatures in my area reach as low as -20F yearly you might benefit from reconsidering your assumptions.

      more important things to argue for

      These are entirely independent problems with independent research teams and are so removed from each other as “battery research” is obviously research, while “infrastructure every 50 miles” is political. These aren’t more or less important, they are entirely independent discussions.

      This argument is so nitpicky and feels like bleed over from reddit. It’s not about anything useful, it’s about you misunderstanding the point I’m making and nitpicking the rhetoric until you’ve decided I’ve said something in a way you would have also said it, and therefore it is acceptable to you. I’m done here, have a good one.
