Its not actually the same. People constantly mix things up because the words people use are so wrong.

Structural packs are nothing new, lots of EV always had structural packs.

What Tesla is doing in the newer Model Y (called 'Structural Pack') is actually structural cells. That's the innovation. Where the cells themselves are glued together and sandwiched in a pack. So the cells themselves act as vertical enforcers. The whole back is basically filled with structural foam.

The only other company that is doing something like that is BYD but that is quite different as those are really big Prismatic cells stacked up.
