You are going to be plugged in constantly as you will only be pulling 1.3 kW. Per hour. The BMS consumes some of that so the full 1.3 kW is not going to enter the battery. On a 92 kW Touring battery, going from 20 to 80%, you will be adding 55 kW (even more on a GT) and probably only adding 1 kW an hour to the battery, so it would take over two days to charge the car - and even longer if the temps are very hot or cold which will cause the B!S to consume more of that power.While 110v works for PHEVs, it is really not a practical solution for this beast.
