Total stop time is not just time spent standing at the gas pump but includes things like going to the bathroom and getting snacks or drinks from the convenience store.

The great thing with an EV is you don’t have to stay there while it charges, so you can do those things in parallel.

You may be thinking of a different context. This is about road trips, not around town fill-ups. On a road trip, people stop to fill the car, get snacks, take a leak, stretch, etc, which is why the average tends to be 15 minutes or so.

You can do faster stops for the weekly fill-up, certainly. But in that case the comparable situation in the EV is zero minutes. The vast majority of owners will spend far fewer minutes on refueling for their EV in a given year even if the road trip stops really did take two or three times as long.
