Visited on November 27 and charged with MOVE RFID on the 50kW charger.
There are now 2 "public" chargers here, though it's not super clear if you can park any time.
The ABB 50kW has been there for a long time. The connector holders and the spec sticker still says it's a DC 20kW / 50A. But it's clearly been upgraded to 50kW as that's what the apps have shown for a long time, and I was able to pull 48kW, indicating the usual ABB 50kW 125A limit.
There's a new Alpitronic HYC_200 installed even closer to the entrance. This charger is already listed in the apps since a few weeks, but with "unknown" status. It's not in operation yet. There's a sign announcing this new offering on both the Alpitronic and the ABB, but the way they worded it, it sounds like the new one is already in service when it's not the case. No mention of the planned opening date. The sign says 200kW, whereas the MOVE app says 150kW.
The sign at the entrance says private, no parking allowed between 6h and 18h on work days. There's no clarification regarding the charging spots. The parking spaces for the new charger have EV symbols, so presumably this one is always open to the public. But it's unclear if the 50kW is open to the public during working hours, as the parking spaces aren't painted any differently.
There are also AC chargers in the next row of the parking, but those spots are specifically marked as reserved for their own vehicles.
I did not try to enter from the north, but I think it can be done, there doesn't seem to be any gate. The best access is from the south, as the chargers are right there near the entrance.
