Visited yesterday without charging.
There are 2 clearly marked Plug'n'roll spots in front of the garage, so I assume it's open to the public.
At the start of July 2023 there were briefly 4 connectors listed on IchTankeStrom. It seems like they created 2 new IDs for the DC charger, but then removed the old IDs and renamed the new IDs into the old IDs.
On Chargemap there are pictures of an AC charger at the same location where the DC charger is now found, so there probably were never any other charger. I walked around the building, didn't see any other charging station or traces of an old one.
The Chargemap pictures also show that there were originally no painted spots in front of the station, it seems like all spots were perpendicular to the road and you parked on either side of the charger. Then later the 2 green spaces parallel to the road were painted while the AC charger was still used. The same spots were re-used for the DC charger.
The Intercharge QR codes look faded, it seems like another case of someone scanning and printing a copy of the original code on an inkjet printer, probably to re-use the original IDs but avoid having to order new tags from Intercharge...
