I don't think superconductors solve anything in the EV charging space, and certainly wouldn't make L2/L1 charging easier to install for shared parking / street-side parking. An L2 charger uses something like a electric clothes dryer circuit, with 240V at 40A. Or somewhere in the 6-10 kW range, to recharge you overnight.
