On Chargemap all pictures show an EVTEC coffee&charge. I don't have any trace of that charger in my Swisscharge historical data, and there aren't any QR codes visible in the pictures, so I assume it was free.
This year the location appeared on Swisscharge with a 60kW CCS, CHAdeMO and AC. The Swisscharge picture shows this is an EVTEC cappuccino&charge, installed at the same place the Chargemap charger was found.
Swisscharge doesn't indicate opening hours. From the Chargemap pictures it doesn't look like there's any gate to block off the TCS parking off the main road.
