Visited yesterday without charging.
This location used to be visible in eCarUp app and IchTankeStrom. It's been hidden but is still active.
Both AC and DC chargers have the eCarUp QR codes for ad-hoc payment and they seem to still work.
The DC charger and right AC have signs "P während des Ladevorgans" but this doesn't seem to apply to the dealership who left an unplugged car in front of the AC charger.
