About to Lease an EV. Charge Station?

Been a while since I've been on these forums

If all goes well, I will be the proud lease(owner) of a 2020 Hyundai Ioniq EV. It can handle 7.2kwh level 2 charging. I am still trying to figure out if that is 40 amp or 32amp 220/240 v.

I have a 200 amp panel in my garage, with plenty of space. I am thinking of an out door 220v/240v oultlet, with a 'level 2 charger' that can plug in.

I cant find any specs on Hyundai website for specific amps. I did find these specs on Amazon for a charger: 7.2 KW charger on Amazon

Here is one from ChargePoint that actually has some specs: Chargepoint Home Charging System

My thinking is to either use liquid tight conduit or (have to brush up on it) BX. In NJ, pretty sure we have to have the wire protected.

I would look for an outdoor rated box and (if I go the Chargepoint route) a NEMA 6-50 or NEMA 14-50 receptacle. Thinking I would use double pole 15 amp breakers (should it be 20?, if I go chargepoint they seem to recommend 40 amp, but its adjustable? ).

Any idea what gauge for a run of < 25 ft? 12-3?

Any advice, as always, REALLY appreciated!

7.2kw = 7200 watts. 7200/240=30 amps. You need to have the circuit at 125% (it's a continuous load) so it needs rated 37.5amps. Round up to 40 amps with a NEMA 14-50 receptacle. So double pole 40 amp breaker with minimum of 8 gauge copper wire.

thank you! 12 gauge would have been slightly undersized... Glad I asked the experts!
