I’m not so sure.
Are we talking about the same thing, there was a recent Tom Scott video on it.
Basically you drive your NIO into this machine and it removes your battery and replaces it. Then it charges your old one and next time someone drives in they may get your last battery. Since and repeat.
Standard and swappable battery packs? Yes. All the skateboard style vehicles or ebikes have battery packs that can be removed and replaced.
Making that automated could be nice but isn't necessary to get the benefits of a standard. A standard forces pack producers to compete with one another in terms of quality and price. It makes it cheaper to install new batteries. And it makes it possible to upgrade your cars range with newer packs. With an EV, you won't need to get a new vehicle hardly ever if getting new packs is relatively affordable and easy. Further, the worn packs still have value so swap locations will be incentivized to pay you for the pack they remove.
The notion this needs to be part of a giant battery swapping network to reduce charge times is silly. 10 to 15 minute charge stops are already very short and all you need on most cars for the next leg of a journey. It also introduces a lot of complexity. Like, what if I want or need a 100kWh pack but the standard is 80kWh packs? What about pack wear? Who's in charge of pulling the degraded packs? And what do we do about someone putting in a pack with fake capabilities? You have a situation where you are cycling parts worth well north of $10k. That's a mighty tempting target for theft.
A standardized battery is still a really good thing. I just don't think it needs to be a part of road trips.
that's not what the top comment was talking about. this is replacing the whole battery, not cells within the battery. it doesn't help with reparability at all.
