Hi,

Welcome to Italy, bienvenuto a Italia. We speak no German as is your change set comment indicating. The quality programs indicates that 110KW capacity is incorrect and in fact capacity is the value to indicate how many vehicles can be charged here simultaneously. Would that be 1, 2, 3, 4? I've moved the 110 KW (space between value and unit of measure) to charging_station:output per the wiki. https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dcharging_station
Ciao
