Chademo is DC, J1772 is AC. There are no adapters for that. Pulling a 240V line for a plug shouldn't be very difficult/expensive though. If you want to use the Ariya's included 30 amp charger, you'll need to do a 14-50R 50 amp plug on at least a 40 amp circuit/breaker. If your existing circuit is only 30 amps, then you'll need to get a different charger that is either set for 24 amps, or can be configured to only pull 24 amps - 80% of the rated capacity of the circuit.I installed a GE charge station for my 3 Leafs some years ago. The cable is hard wired in the station and has a chademo plug for the car.
I expecting my Ariya in the next couple of weeks and obviously need a chademo to j1772 adapter. Do they exist? I've poked around Amazon and can't seem to find one.
If needed, I suppose I can open up the charger and pull a 240v line out of the charger to a 30 amp 240v plug for the Aryia's Level 2 cable.
