A robot just swapped my electric car's battery

  I love the idea of charging and easy to replace batteries.

    I have to ask why? I can’t see any positives outside of fleet vehicles and there are plenty of negatives.

      Speed, for one. 5 minutes vs 30 minutes to an hour to be fully charged. Makes a big difference for road trips.

      Repairability is massive.

      I find this kind of comments so stupid. The technology is well beyond proven. Logistics have had swappable batteries for over 15 years since the time of acid batteries. Nio is a rental company first and for them the model seems to be working. It’s compelling for road trips specially since most of the charging stations are broken most of the time and for extremely dense cities where people aren’t allowed to access power plugs at parking spaces. I mean, on the suburbanite hellscape, charging at home will always make more sense, but the US is not the entirety of the world. This things seem to be ripe for success in Asia and Europe.

      20 below and you can swap out the battery quickly. Can’t charge it if it’s dead.

  I believe battery and charging technology will eventually overcome the need for this.

    Probably not.

    Battery energy density is just about as high as it will ever get while still being a fraction of the density of gasoline. You can’t simply dump more energy into it, physics is the limit here.

    You can maybe charge a bit faster but I think we’re hitting a ceiling there as well.

      That, and the internal combustion engine will never replace horses.

      I dream of F-Zero type charging

      You lack imagination. What if they had multiple smaller batteries, as some cell phones do? The big reason it’s not more common in phones is that space is a massive premium, which is less of a concern in cars. Weight is a bigger factor here.

      EV batteries have hundreds of cells that could potentially be charged in parallel. It’s even possible to do battery swaps one cell at a time, albeit that’s unlikely.

      And these are just possibilities that I came up with as a non-EE. I’m sure they have their flaws, but it would bypass those physical limits.

  Anyone have knowledge of Nio and the long term viability? Are they targeting the US, or just China and Europe?

    It will be nice to have the options for EVs.
