Visited on July 5 and did a short charge with eCarUp app.
The chargers are in an outdoor parking. Every single parking space is assigned to a business. The parking space numbers shown on eCarUp must be part of the design plan, but are not visible on location, except for their presence on the eCarUp sticker on each station. The signs in front of the parking spaces have different numbers per business. 1-8 match with EWGA 1-8. PP13 is EWGA 28. PP14 is "Lebensart Besucher". PP27 is EWGA 12. There's a placeholder on the back of charger PP27 for an additional station.
All stations have an attached cable.
At the entrance there's a sign forbidden parking, "Mo-Fr, 6h-18h, Ausgenommen Mitarbeitende EWGA, Besucher Lebensart und Sammelstelle". Nothing clarifies whether the chargers are intended to be open to the public outside of those hours.
