Thirty minutes is ridiculous. That is not "rapid" ANYTHING.
The only real solution is to streamline the process of swapping out battery packs, or, ideally, hydrogen fuel cells.
This is where hydrogen fuel cells really make sense. They are the ultimate battery pack. They are interchangeable modules. You stop at a filling station and replace your depleted fuel cell with a full one in fewer than five minutes.
I know Tesla has a battery pack replacement service, but it really needs to be affordable and streamlined and not require expensive robotics.
NOBODY wants to wait thirty minutes for "rapid recharge." The money spent on this infrastructure should, instead, be spent on optimizing the use of hydrogen fuel cells. They are the ultimate battery and they don't wear out.
