There are now chargers visible on eCarUp at this location.
There's one 11kW AC charger named "VW" to the east, it must be the one from my first picture in March.
Between the building there's a listing with 2 plugs, so I'm not sure what it might be. I had seen 3 chargers there in March. The charger data is probably not correct, it says a CCS 22kW and an AC 50kW. The CCS might be the 24kW ABB I had seen. Not sure what the AC is since there's a pair of evbox chargers. Maybe only 2 of the evbox is open to the public.
There are no instruction or timetable in the eCarUp description , not sure if/when you can use them.
