The cost is going to depend on how much your electrician charges to do the install. The hardware for a level 2 charging station runs about $500.
In my case... we have a 240v line that currently powers a large A/C that runs (on the outside of the house, in conduit) to the corner of our carport. The cost to repurpose that line to connect to a charging station...about one hour of an electrician's time (assuming I didn't just do it myself). So it really depends.
Now obviously, the cost of installing charging hardware has to factor into your (anybody's) car-buying calculations. But as part of a $35,000 purchase (more or less; that's a Hyundai Kona EV), the cost of the electrical upgrade isn't a lot.
Now, $35,000 sounds, to me, like a lot for a new vehicle. But I did a quick check - the base model of the most popular pickup truck in America (the Ford F-150) is... about $35,000. Personally, I'd spend the same amount of money for a Kona over an F-150, in a heartbeat. But I don't need, or want an oversized vehicle; I don't haul sheetrock or plywood (or pianos, since I turned 30, some 40 years ago!); my wife and I can get everything we need to take for a two-week sojourn in the mountains of Sullivan County in the back of my Toyota Prius C (with the back seats folded down); we do this several times each summer. (I am blessed with a spouse who has never, to my knowledge, ever attempted to travel with the kind of stacks of suitcases you see caricatured in the movies!)
If you want a hybrid, a 2024 Prius base model is less - about $28,000. Yes, if we were replacing our 2005 Prius today, we would have to weigh the cost difference between a new Prius and an EV. Based on what we've spent on routine maintenance of our two Priuses, (plus fuel savings), I could probably make an economic case for the EV. I haven't run the numbers in detail, because we're not actually in the market. And the longer we wait until we are in (forced into) that market, the smaller the upfront differential between the two options will be.
When I bought my 2014 Prius C, it wasn't because I had to have a hybrid; but even then, ten years ago, my spreadsheet told me that the C was a better option than a bunch of other vehicles I considered - somewhat higher upfront cost, but large savings over ten years on fuel (and my assumptions about gasoline costs over ten years have pretty much come true). When the time comes, I'll do the same kind of analysis - comparing 50 mpg in a hybrid with the equivalent mileage/KwH of an electric, making real-world assumptions about likely gas prices vs. electricity costs over an assumed vehicle use lifetime (at least ten years for us, likely considerably longer). It's just math, and MS Excel and I are old friends.
