That is interesting.

One of the things they need is processor for individual cells that make up a battery pack. I'm calling it a processor because a processor is like a million switches and like a million switches are what is needed.

The problem with battery packs is if one cell element fails the whole pack fails and although it is possible to replace just one bad cell to fix a pack that kind of repair is impractical. When fixing things it is often cheaper to replace large assemblies if there is any possibility that the repair would be unreliable if smaller sub assembly replacements were attempted.

What a million switches would do would be to allow a computer to assemble a working stack of cells into a pack without their physical location being a factor. A bad cell could be isolated and ignored, a working cell linked into it's place to complete a working stack.

A battery pack could be added on to to change the range, or to make up for the fact that some parts of the battery were becoming aged, some of it could be located here and there in the car.

For long trips a suitcase like range extender could be rented and set in the trunk and be easily linked up to the cars onboard batteries. All of that becomes possible if like a million switches are available to link it together, in essence a battery processor power chip.
