Comment on BYD Reveals the ‘World’s Longest-Range EV’ as American Auto Industry Struggles to Keep Pace

  There was at least one company several years ago that was trying. Go to a place and pay a fee, kind of like how you’d swap out a propane gas bbq grill tank. They’d forklift out the empty batt and forklift in the charged one, was their game plan.

  The tech is all too knew for standardization. Too many chemistries and voltages and places to figure out where to stick batteries.

  If what catl is producing right now is correct and true, we should be all set in the coming future. Supposed sodium batteries at 175wh per kilogram and over 10,000 charge cycles and very fast charging. Great for sub 300 mile range small econo vehicles. Then the solid state lithiums they’re working on are also supposed to have a high amount of charge cycles and energy densities close to 500wh\kg, which will give plenty of range and make the cars lighter, which is really needed to ease up on suspension and efficiency and tread wear.

  Not practical, no one wants it.

  People are already bitching and moaning about how hard it is to build out charging, when it’s based on existing electric system that’s is already everywhere. You really think it’s at all practical to build out everywhere a network of station width a large inventory of one ton batteries to fit every age of every vehicle in every location no matter how rural? You want to hold battery technology stagnant to support this? You want to lose the efficiency and reliability benefits of structural batteries.

  The reality is current batteries already last longer than the first owner keeps a vehicle and newer ones easily exceed lifespan of ice vehicles. The reality is charging is already more convenient that battery swapping. The reality is building out chargers is much easier than any other infrastructure

    It works with propane tanks.

    one ton batteries to fit every age of every vehicle in every location no matter how rural and heavy automated equipment to maneuver them?

    That’s where standardization comes in. All vehicles would use the same cells, or maybe a couple sizes depending on use case. No reason they have to way a ton either a car could have multiple cells sized for a person to be able to handle themselves. This would also allow you to “top up” if they can get the cells to drain sequentially.

    You want to hold battery technology stagnant to support this? You want to lose the efficiency and reliability benefits of structural batteries.

    As long as new technology connects to the old connections then they can change whatever they want inside the cells. That’s how batteries have been for pretty much the entire history of batteries. And no I don’t want to lose anything. I was merely asking a question.

    The reality is current batteries already last longer than the first owner keeps a vehicle and newer ones easily exceed lifespan of ice vehicles.

    I’d very much like to know what the actual numbers are for “how long the first owner keeps a vehicle” and the “lifespan of ice vehicles”. I’ve had my car for 15 years and I’m the first owner. My dad had a truck that’s coming up on 40 and is still kicking. EVs haven’t even been around long enough to prove that

      Everyone has different definition of lifetime and very few keep theirs 40 years

      I personally buy new and keep it for its lifetime, as defined by “needing more work than its value “. That has worked out to be 12-15 years for ICE cars. For an EV I’m reasonably confident will last longer and the vehicle Will still have a small amount of resale value based on batteries degrade rather than stop

      Also I’ve seen quite a few articles like

        Tesla’s haven’t existed for 20 years. How can that be the average lifespan? At best it’s theoretical. Most likely it’s some musk stooge making shit up.
