Comment on A robot just swapped my electric car's battery

  You have that backwards. The vehicle is good for the life of the battery. We could design EV where the shell and motor last 30 years, and the battery just swaps out every decade or so.

    That’s already how it works

    Batteries in EVs are replacable, it’s just not a quick and simple process at the moment

    Very few cars now last 30 years. The US average is 12.5, which is about how long EV batteries are expected to last.

      But you still have it backwards.

      We could very easily design and build a car that lasts 30 years. But we don’t, because manufacturers don’t want them to last that long.

      Evs don’t have transmissions, or complicated engines, and the wear on brakes is much less with regenerative braking.

      Other things like air conditioning and interior coverings could be easily servicable

      Why should the life of an ev by limited by its battery?

        Cars get in accidents all the time, many of which will total it. Over time, the probability of that reaches 1.0. Most cars will not make it to 30 years regardless of how well they’re made.

    I don’t think so. Think of the engineering challenges. The battery would have to be a separate structure so more weight, less range/performance, more wear on tires and brakes, less rigidity unless you add even more weight, etc.

    Batteries can be replaced now. It’s just a time consuming job but one that might only need doing once.

  Can’t tell if this is a serious comment or not… Sure a battery will last as long as the car, but it’s of limited use of it only holds 30% of its original capacity after 7 or 8 years. Sure. It’ll do 75 miles, so still useful for city drivers, but not for its intended use.

    EV batteries lose about 1-2‰ per year. At the high end, that would be down to 78% after 10 years. A 300mi EV would still do 230mi.

    Yep! Thats about what I think. I will not buy a car that are like most modern day cell phones. If the battery dies, I want to be able to replace it. Even better if there is a easy charging station like the above and giving the consumer more options.

      So far most ev batteries do much better than cell phones, as long as they have cooling.

  Nope! They are not.

    I don’t think that’s a fair statement in relation to EV batteries. Most of them are proving to last well over 10 years.
