You don't have to, it makes it a lot easier that you can do it.

You can also charge supercapacitors and uncharge it very fast if you like.

You can use the whole capacity of a charging park for just one car (if not a lot of cars are there).

You could also do a more classical gas station setup instead of a charging park. Cooled cable, 1-2 proper ports on the bottom etc.
