There are now pictures in the Swisscharge app showing the station was replaced by an EVTEC crema&charge with 2xCCS.
This change is probably recent, because the 50kW power is only advertised after a long period where the DCs where out of service 2026-05-16 to 2026-09-07. The AC remained active until 2026-07-09 and the new charger probably doesn't have AC (that's not an available configuration), so before September 2026 it must have been a different charger.
But annoyingly I cannot find any confirmation of what the setup was until then. The distribution of sessions between connectors suggests they were indeed both CCS. But there's also a lot of activity inconsistent with a sequential charging mode, so it seems unlikely to have been the coffee&charge either.
Another oddity is that the internal ID for CH*SUI*E35107 did not change, suggesting the computer or configuration was moved from the old charger to the new one, but I would be surprised if that was possible at all given the difference of age of the old and new charger. But not completely out of question as both are EVTEC.
The Swisscharge API shows that the charger model changed from 10909.0A to 16321.3A this September. But nobody shared a picture of the old charger's sticker where we can see whether the serial matches. It also seems impossible to confirm which exact EVTEC model is 10909.0A online, but I know of a location with a charger with the same model number, the coffee&charge at SAP Regendorf. That other charger shows a build date of September 2019 and 60A DC cables. I went through all the coffee&charge documentation I can find again, but I cannot confirm whether concurrent DC sessions are possible. I'm pretty sure it was not possible on the earlier models, but maybe it was added later? The coffee&charge also doesn't seem to broadcast the SoC on Swisscharge, so I cannot use that information to check if 2 cars were ever charging concurrently.
While back on Virta the connector metadata was never updated, it seems like the change from CHAdeMO to CCS must have happened all the way back on 2024-10-09, because that's the point where CH*SWI*E35108 started showing many more sessions
