Visited on January 12 and charged with Swisscharge, no issue.
The charger is accessible off the main street, but only in the southbound direction.
The other parking spaces around the charger appear to be private. The charging spots seem to be free to park. No maximum time posted.
The charger is indeed a model with 43kW AC.
Something happened to me for the first time, the charge stopped with a "communication" error after running fine for a while. I had enough electricity so I didn't try to re-start the session.
