Visited yesterday without charging.
The AC chargers are installed all around the garage, some in Besucher spots, other in private spots. None of the spots are reserved for charging. The stickers have Eniwa branding and QR codes for ad-hoc payment.
I thought there were only 6 connectors, so I stopped looking after the 6th, but actually there are 2 more in the data that I didn't see. I think they are probably outside as well, just further on.
Shoutout to the ridiculous "100% plug-in hybrid" stickers on the cars, they really don't know what to say anymore...
