This location was visible on Chargemap and Google Maps, with 2x DC and 3x AC, connected through E-Flux backend, at least as far back as August 2024.
Now the DC connectors have appeared on Swisscharge. There's a bug, where the location name is glitched with a E.ON location in the Netherland. The roaming name is "LKW-Parkplatz, Eistrasse 24, 6102 Malters", while the Swisscharge plug name is "LWK Parkplatz con:01" (and 02). There's probably a typo in the plug name.
There are no pictures on Swisscharge yet, but based on the older pictures it seemed to indeed be a charger for trucks.
