Don't worry, the $7500 per EV credit looks like it is unaffected. The refueling property credit (e.g. for installing HPWC, 14-50, or other EVSE) looks to be limited or eliminated by an AMT calculation, even for some people who aren't otherwise affected by AMT. I didn't spend a lot on my 14-50 outlet, but so far it looks like I won't be able to claim any credit for it. I'm definitely still eligible for the $7500 though.
