Mrdr_ev - says "I suspect you have your car set to run at the reduced charging rate" No-there is no option to do this on the Leaf as far as I know. It may be that it already had 68% charge so was on the downhill run. Maybe if I put it on when the residual charge was less than 10% there would have been a larger current draw. Frankly I don't know, but it would be nice to get someone else's input on this. I would hate to be proved wrong but am humble enough to admit it if I am.Weird, that's only ~900 watts at 3.6 amps that seems to be very low, so I suspect you have your car set to run at the reduced charging rate. Bet it takes forever!
My BMW on the granny charger settles to around 10 amps for the duration of any charging session, which can be up to 18 hours long if the car is low. This will still be fine on any reasonably modern ring main in a house.
