A plug-in charger uses a 240V NEMA 14-50 outlet, so it is easy to swap or take with you. On the 50A circuit a 14-50 outlet normally uses, chargers are limited to 40A continuous. Hardwired units connect directly to the circuit, which lets them run at 48A or more and avoids outlet wear. Many installers prefer hardwiring for outdoor installs.
EV charging is a continuous load, so the breaker must be rated at 125% of the charger's output: 16A→20A, 24A→30A, 32A→40A, 40A→50A, 48A→60A. Also check your car's onboard charger limit, because extra charger capacity beyond it adds no speed.
Installation cost depends mostly on your panel's spare capacity (a panel upgrade or load management may be needed), the distance from the panel to the parking spot, the wire gauge and conduit, indoor vs. outdoor runs, permits and inspection, and local labor rates. Get quotes from licensed electricians, and check your utility and local incentives.
If you drive a lot or need a fast overnight top-up, it usually helps. Many low-mileage drivers get by on Level 1.
