The idea is that because an EV doesn't have an engine/transmission, it doesn't really need a hood. So the idea is that you simply remove the hood and making all that space "interior" space instead. This technically would reduce design complexity and allow for access while inside the vehicle, minimizing aerodynamic drag, and maximizing interior volume. Would this even be possible?
Most EV batteries are pretty big, but they are flat. Usually they are basically the floor of the vehicle ("skateboard"), about 6 inches tall. There's nothing from a mechanical/electrical view that requires they put anything in the front hood. Even components like the battery HVAC could be placed at the rear. The front hood (frunk) is largely for styling, convenience, and crash safety.
BTW, this was also (mostly) true of ICE vehicles. Mid/Rear engine designs exist, but that weight distribution causes handling and traction issues.
