A regular household plug should be more than enough unless you want to use your home as a quick pit-stop between two long rides. (e.g. drive 150km from work to home, then drive 300km to your holiday home for the weekend an hour later).
Typical EVs nowadays get about 6 km per kWh, the average driver in the US drives about 54 km. A US home typically has 15A plugs, or 20A in the kitchen/garage. That's 1.8 - 2.4 kW. Even at 80% safe continuous charge, you'll be averaging 1.5 kW at minimum. So that's just 6 hours of daily charging at minimum.
If you have a garage and plug in when you get home, your car typically sits there from 8PM to 8AM for 12 hours. That's already double the time necessary to charge 100% of your driving at home, at the minimum charging speeds equivalent to a microwave or washing machine. And you'll typically have much more time with the car plugged in on weekends and home-work days.
A 5k upgrade to the electrical box might be a good idea, but it's definitely not necessary for most normal EV users.
As for ROI, a Corolla might get 20 km per liter, in Connecticut that's 6c per km. An EV even at the 29c per kWh is just 4.8c per km which is 20% cheaper. If you have some solar panels you can cut that figure by another 65%.
Not to mention the lower maintenance costs for EVs and the rebates various local governments give.
