After the migration to eCarUp, there are now 4 connectors listed here. I can't find any confirmation there were ever 4 chargers while on Evpass.
If a second charger was really added, they used an old unit, because the eCarUp names show the serial numbers, and one is from 2017 and the other from 2018.
Most likely, one of the chargers is placed at the wrong location on the map, but I have no way of telling which without visiting.
