Nio is a Chinese auto maker that offers an alternative to charging: just swapping out the whole battery whenever you need it. I borrowed one of their cars. ■...
This is already what they do. Dry batteries that are bigger than about your phone are generally comprised a whole lot of battery cells. If you ever take em apart, you’d basically see the cells are made up of what looks like a whole bunch of AA batteries (but larger).
They do charge “in parallel”, but that’s limited by how much electricity you can feed through into the system as a whole, and doesn’t speed up the process, it just makes them all fill at about the same rate.
Making the cells swappable is basically what this video is about.
