Depends on the charger.. It may have integrated ground fault protection And the "smart" word covers over a lot of potential features, like stopping/starting charging based on electricity prices, doing load balancing between multiple chargers, reporting usage to the cloud, etc. It's also an outlet where you really want to be sure that everything is professionally done, and up to spec, because drawing maximum currents for hours and hours is very demanding on all the parts. There can be significant heat generated in the wiring and contacts.
