22 years is also amazing and way cool.

Well...I guess I have a few more weeks than you do

Having an EVSE that is capable of supplying 48A does not mean that the car will ask for 48A. The Car and EVSE handshake on the amount of amps the car will draw from the EVSE up to the maximum amount of current the EVSE can supply. Depending on the car and EVSE, each can be set for a maximum current level.

There isn't a handshake. The EVSE simply indicates "I can supply 48A". The car then decides how much it will pull, which is the lesser of what the EVSE can supply or what the car can pull. 48A EVSE, 32A car, car pulls 32A. 24A EVSE, 48A car, car pulls 24A.

Congratulations on the new Ariya.

Any EV car will communicate with the charger and limit the charger output to the most the car can take. I believe the Ariya is limited to 32 or 30 amps, as was my Nissan Leaf.

You are smart installing a 48 amp hard wired EVSE aka "Charger" so when you get your next EV you can charge at 48 amps. The electrician will know when reading the installation instructions for the charger that the 48 amp charger needs a 60 amp circuit.

The car does not communicate to the EVSE. The EVSE merely says "I can supply a maximum of X amps." It is up to the car to control how much it pulls from the EVSE. The car pulls the lesser of what the EVSE can supply and what the car can do. A car that can only do 32A will only ever pull 32A even if the EVSE says it can do 48A. And if the car is plugged into a 24A EVSE, it will only ever pull 24A.

Hardwiring is inherently more robust electrically than using an outlet as there are less electrical joints in the circuit. Each joint (connection of a wire to a screw or a socket to a pin introduces some resistance and therefore heat)

One recommendation to add: Have the electrician come back out and check the torque on the screws in 6 months.

You might want to watch these to be better prepared to work with your electrician:
