My Leaf would charge a lot faster than the Zoe if i had a rapid charger installed at home 3 phase, the public locations are no faster unless the sites are 3 phase. Hence 33amp or to put it another way you can't get 22kv out of single phase electric. Zoe home use and Leaf if fitted with 32amp same out and about Leaf rapid faster charging times.The ZOE and the Leaf will charge at the same rate at home on a 7kW (32A) Charging Station. Obviously, the ZOE would charge a lot faster at home if you had a 22kW (32A three phase) Charging Station.
At public locations the ZOE will be faster than the Leaf at 22kW locations. However, the ZOE is probably slower than the Leaf at 'rapid' locations with 50kW CHAdeMO (DC) and 43kW Type 2 (AC). I say probably because their is some anecdotal evidence that the ZOE drives further than the Leaf for the same amount of electricity. It's further complicated by the battery chemistry and charging algorithms (the Leaf seems to be very aggressive in it's charge rate reduction between 80% and 100%). IMO we would need to test the ZOE and Leaf charging side by side to know for sure and that's probably not going to happen
I believe that the OP was talking about public charging at a 22kW location so I'm not sure how any of this is relevant. Did I miss something?
