With only a 150mi range EV, a 15-20 min fast charge would be enough to comfortably do the return trip that same day without range anxiety.
Existing gas stations (or parking lots) could serve that use case, which is fairly common in the US, where mid distance trips are almost completely car based.
Today, they could charge the same or lower price/mile-of-range as gasoline and make a large margin, since electricity is less than half the price of gasoline per mile (at retail prices, there's an even bigger difference with wholesale prices).
You could comfortably do that entire trip on a single charge with existing EVs. Volkswagen is about to release their ID.3, which which has 3 variants ranging from 205-340 miles of range. In a year or two, the range anxiety "problem" with EVs will simply be a noop as EVs will have longer range than most ICE vehicles.

Because they are cheaper. And many will by high mileage EVs on the used market. A 200mi EV will have a lower usable range later in it's life, but otherwise work great. For example, I can imagine buying a used Chevy bolt for my kids to use around town 8 years from now.
But on the price you make a good point. That will come down over time as more and more companies make good EVs.
A Volt is a PHEV, which is an ICE+EV, with the associated complexity and wear.
Pure EVs, however have far fewer parts to replace, and put very little wear on those parts. Most of the wearing parts are pretty generic, like tires and brake pads (the latter being replace rarely). AC induction motors also have a very long lifetime.
The most specialized part on an EV that wears the fastest, the battery, is reusable/replaceable.
Already today, there are people taking battery packs from totaled Teslas and installing them in classic cars like the VW bus. There is a shop in southern CA replacing drivetrains in classic cars w/ EV drivetrains [1]. So I can totally see replacement batteries being produced by aftermarket manufacturers for existing EVs in a number of years. Of course the vehicle manufacturers themselves probably won't supply those replacements, but cars aren't mobile phones, and I bet that right-to-repair will resonate with people a lot more with EVs.
At home, I charge using power from Exelon's nuclear fleet at 1-6 cents/kwh (Time of Use plan). I want to stress: most people will plug in every time they arrive at home and charge at home. You will leave your house every day with a full charge by doing so. Supercharging costs me ~30 cents/kwh, so $10-15 for an 80% charge. Regardless, the costs are so low I don't care either way, I come out ahead versus gasoline (previously $40-60 per fill up) no matter how I charge. I literally don't even think about it when Tesla dings my credit card for Supercharging. It is annoying to use a J1772 public charger (install adapter, swipe Chargepoint card, troubleshoot why the station isn't providing current), so I avoid using those whenever possible.
In the US, you are never more than 150 miles from a Tesla Supercharger, and of course the network will continue to grow over time: https://supercharge.info/map
This isn’t economically practical unless you have subsidized charging. It’s significantly cheaper to charge my car at home than it is to use some random public charger.
