Visited on Sunday, February 9 without charging.
On eCarUp and IchTankeStrom there is one DC charger documented. The power is indicated as 0kW, but the location name indicates it's an ABB 124, so probably around 124kW max.
On location there are also some AC chargers. The "Werkstatt" area can be seen from the main road and car wash. There are 4 parking spots indicated for charging, with 2xAC and the 2xDC. All are equipped with eCarUp QR codes, and the AC seem to be working as well, despite not being visible on the public map.
There are also 2xAC between the workshop and showroom, but those don't have any QR codes.
All eCarUp chargers have a base fee of 6CHF/h, AC is 55ct/kWh and DC is 110ct/kWh 😱
