I took my car in for service today and noticed an EV charging and started talking to the workers about it. They said there is no cost and never will be a cost to charge as Kia corporate covers this for all certified dealerships. They said the only maintenance you need are tires, cabin filters, and brake fluid changes. I would think there are other things they are forgetting like replacing windshield wipers, but if gas prices stay high the costs of owning over time could become comparable to gas powered vehicles.
However, the range is the issue. Currently it is 100 to 520 miles and would not work for me, since I would never get a home charger and run up my electric bill. That defeats the whole purpose, plus my utility company uses primarily fossil fuels so it's not green either.
I asked my boss once about getting a charger at work as there aren't many around and it would draw people to our store but he said no.
