For reference, I had a ChargePoint Home Flex ($700) installed in my garage (50 AMP unit with 40 AMP output). I didn't have the right wiring to my garage so had an electrician rewire it and install the charger for approx. $1800. The electrical panel is on the opposite side of my house so that covered wiring across the length of my house, although I don't know the exact amount of wire used off the top of my head.
Residential EV charger installation also currently qualifies for a federal tax credit equal to 30% of the equipment and installation cost, up to $1000 if I'm not mistaken. in my case, that effectively reduced my bill by $750, which left me $1750 out of pocket. I didn't benefit from any state or local incentives but there are a lot of those out there as well.
