Visited yesterday without charging.
There are places that don't put enough signage for their chargers, then there are locations like these that almost over-do it. I had not even planned to stop here, but I couldn't miss the huge "Ladestation" sign visible from the main road.
There are a few levels of parking when you drive down the ramp. When you reach the loading dock area there is another sign pointing to more parking spaces and the charging station down a narrow ramp.
I'm not sure if there's supposed to be even more parking, because in the bottom level there's a closed gate to the right (not visible in my pictures). So maybe there are other charging stations. I found just the one at the bottom of this ramp. It's also possible the closed gate gives access to the store, as there are shopping carts on that level but I doubt you are expected to push them up and down the car ramp.
The charger is installed in a handicap spot, but the paint is so washed out that it probably doesn't count anymore.
There'a QR code for ad-hoc payment through Saascharge. The QR code seems to work, but it point to a different charger ID than the one visible currently on IchTankeStrom at these coordinates. The one on IchTankeStrom has been showing unknown status for months so it was likely replaced in the meantime.
To exit, you need to go up the same narrow ramp. There's a red light at the top of the ramp but I don't know if it automatically triggers when someone enters in the opposite direction. It won't be fun for whoever needs to reverse.
There are no gates to the area I visited, I was able to enter on Sunday.
