This location recently appeared on Swisscharge and Opendata.
On Swisscharge there's a picture for the first charger marker which shows the entire setup. It's all Hyperchargers in a single row. The picture has an overlaid text "Grösster Ladepark des Tessins in Betrieb". It seems like they have contactless readers, but they might not be enabled.
I thought the picture might be from some sort of press release, but there's nothing about that location on their website.
The power levels are a bit odd. There are 400, 300 and 200kW chargers but they aren't in the most logical order. We also don't see how the power is advertised on the pictures.
Chargers 1/2 and 3/4, presumably on the far right, are 400kW. Is this finally the first public 400kW charger of Switzerland? It's either this one or driv-e in Sargans, but it's unclear to me at this time if the 400kW are open to the public in Sargans or only the slower ones.
The other chargers are presumably also HYC_400 with fewer power modules since it's all in multiples of 100kW. It's odd that it alternates between some 200 and 300kW instead of grouping them by power.
