Yes, you need three phase, so in the US not really feasible unless you have commercial power.
Cost with easy access to three phase is probably around $20k.
There is absolutely zero reason for DCFC for residential use. 40 A 240 V should be plenty unless you drive hundreds of miles every day and need to charge in the middle. A car with short range like a Leaf benefits more from DCFC since you are more likely to need the added range intra day. It is unlikely you would run out of range during the day commuting and working with a Bolt EV (city range up near 260 miles or more) where you couldn't recharge overnight on level 2. If you would regularly have a problem with this it is the wrong vehicle (or convince somewhere near work to install a DCFC).
