Yes, this video is not about the ID.4. It's not even about VW. But it is a very nice introduction to how a BEV works. I drove a Bolt EV for three years and never learned what was happening inside those boxes under the hood. This video, by a Professor (Perfesser?) at Weber State University, lays it all out. He says that, regardless of the shape of the boxes or the layout, the basic elements described in the video apply to all BEVs. All you electrical engineers can skip to the next post.
