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

  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.

        Yeah and that’s why I’m not advocating for 100 year cars.

        I’d be pretty happy with 20 years to, but 10 just feels like planned obsolescence.

        I also messed around with the math very loosly, and only accounting for ceashesgot off the road was in a crash, they could be expected to go 20 years or more without a crash on average.

        And that’s now with all the terrible driving that happens, especially at night. With slight deacrease in accident frequncy that number can increase a lot.

        So maybe 30 is a bit much for now, but its still like an ev that would claim to last 20 yeara.

        Exactly, making it repairable and making the parts swappable will extend other cars lives, especially if they standardize around certain parts like batteries.

  You have that backwards.

  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.
