Visited yesterday.
The chargers are installed but not yet turned on.
It's a brand new EVTEC model "crema&charge", not listed on EVTEC website yet. The spec sticker says 2 outputs max 920Vdc/150A. Input is 400Vac/80A, so that would be about 55kW. They are listed as 50kW on IchTankeStrom, so I presume that's the official rating. This model can probably theoretically receive the EVTEC contactless reader since it uses the same screen/RFID combo as other EVTEC models. It's impressive how compact it is, we've come a long way already from the ABB Terra 53.
The Migros has 2 parking lots. The chargers are in the one under the store, accessed from the Roberstenstrasse. The parking has no gates, there's a parking meter. The first hour is free.
