Visited on June 10 and did a short charge with eCarUp app, no issue.
The opening hours listed on eCarUp app are also shown on the screen of the station. Not sure if that means visitors to the town hall can or cannot use it during opening hours, or is it exclusively for city vehicles during opening hours.
Before charging, the screen shows 22kW/22kW for both sides. When charging at 10kW, the other connector is listed as 17kW. So it seems like the power is shared, but there's more than 22kW total. I could not find the make and model of this charger anywhere on the unit or screen, never seen it before.
