Many condo complexes have underground parking, with stable year round temperatures. I think most forum members are dramatically underestimating the cost for installing complete L2 charging systems rather vs the cost of a simple 110v outlet.
a NEMA 6-20 can use the same gauge and # of wires as a NEMA 5-15 or 5-20 i dont understand why it would cost vastly more? complete level 2 charging at 8~10KW sure that could require major infrastructure changes
