How much do you drive in a year? What kind of car are you looking at?

For the average driver, a 120V (normal) outlet on a smaller car is actually perfectly fine most of the time. If you think you might get a bigger car, or multiple EVs, you may want to look into a level 2 setup. And while you're at it, use thicker wires so you can run more power through it. But don't feel like you have to go overboard. I think the sweet "buy once, cry once, hard to come up with a situation where this isn't enough" number is a 50 amp 240V circuit running a 40A charge cord (always charge at 80% of your circuit rating, max).

But if your panel can't take it or you want to do it cheaper or whatever, a 20A 240V circuit is on the lower end of the level 2 spectrum and it can still do a lot... Like, more than double that "average driver" amount for level 1. And here's the fun part: everyone is so afraid of 240V and think it takes special wiring or whatever. It really doesn't. I've got a 240V air compressor outlet on a 20A circuit, just like what I suggested a minute ago. It uses the exact same wiring as the 120V next to it. The only difference? It's connected to two "opposing" hots with a double breaker (not terribly more expensive) rather than a single hot on a single breaker plus a neutral as you'd see on 120V. All you need to do is wrap the white wire (usually neutral) with a colored (not green, that's ground) electrical tape to indicate that it carries current. Do it on both sides. Easy peasy, up to code, and uses really affordable wiring.
