Visited on Monday and did a short charge on connector 1 with Swisscharge app.
There's no indication that these chargers are public or that the parking spots are reserved for charging. In some roaming apps they are called "AarPower". On the charger there is only an Eponet QR code.
Unit 4 indicated out of service in the apps and also on its screen.
Before I started my charge, the screen on all 3 working units indicated max 100kW at both 800V and 400V. After my charge started and while I was pulling 67kW, the other 2 indicated max 50kW at 800V and 75kW at 400V. It's interesting that there was more power available at 400V, but that's normal based on the way the Kempower power modules work. This means there must be 6x25kW power modules equipped, which matches with the 150kW indicated in roaming apps.
I actually wonder what happens if all cars request 800V. The first 3 cars will get assigned 2 modules each, and there won't be any power module available for the fourth stall, for either 400V or 800V. They can't take any module away from the 3 ongoing sessions as they need 2 to maintain 800V.
I didn't see where the power cabinet was hidden. The cables go around the building and it must be somewhere in the back.
