Ah,so the Kia travel charger does not detect 120V input to set its 12A pilot signal pattern, it detects absence of voltage between ground and one phase as "this must be 120V". So, you want to trick the EVSE to think that it can always send the 20A pilot signal even when plugged in to 120V by floating the ground pin in between the neutral and phase using 2 resistors. This will also mean that you will be overloading the normal 120V outlet, even if it is a "20A" outlet in an attempt to charge approx 50% faster. I can only suggest that you increase risk of fire so monitor for temp change very regularly - I have already replaced or repaired 2 outlets while my truck never draws more than 15A and both were on a 20A circuit. I had an outlet overheating on the *opposite* side as where I charge, because that is how the power was coming into the garage - via wires stabbed into the back of outlets and one of them was high resistance - already completely blackened. So, I scraped it clean to the metal under the screws and attached the wires there instead of in the knife contacts in the back. Success,

I'll have to dig through the user manual and the shop manual. I don't expect to find out anything about this in the user manual. Especially when I couldn't get a straight answer from Kia about whether there was a current limit built in to the on board charger for 120VAC input voltage. They wanted to know how I was going to tell the charger more than 12A was available even though I told them I could get a level 1 EVSE that was capable. I can only test it to 20A but I assume it could do up to 27.5A since it has a 6.6kW charger so at 240V that would be 27.5A. At least I can verify that a 2016 Kia Soul EV will charge at up to 20A on 120VAC which can come in handy when traveling and the only outlet available is a 5-20 or a TT-30.
