This location is not on opendata but I noticed it in MOVE and Swisscharge apps.
It's listed with 2x 450kW CCS plugs, which would make it the fastest charger of Switzerland, but I am very skeptical of this information.
I can't find any picture in MOVE, &Charge or Chargemap apps. But the company of which the charger is named after in MOVE has an article on their website about the installation of an Hypercharger at this address https://solpic.ch/projekte/hypercharger-ilanz/ In the pictures it's an Hypercharger HYC_150, so there's no way it goes past 150kW.
There's still a possibility they installed a different, higher-power charger since then but I doubt it.
