It's being solved from both ends, on one side fast-charging is getting faster and on the other end the range is increasing. If the range is 600+ miles, you probably wouldn't mind a 30 minutes charging time because you want to stop to eat anyway.

On the other hand fast charging still has issues with capacity. If several cars want to fast-charge at the same time, there either aren't enough spots or when there are the charging rate is decreased because there isn't enough power available to fast-charge many cars. And this is with a minority of cars being electric, if everyone switches to EVs this problem becomes much bigger.

There is a lot of work to do on the grid and maybe some form of local storage of energy at larger highway charging stops.
