It's unclear from the data online what this location is.
There used to be a charger listed on the old Swisscharge platform and IchTankeStrom until January 2021.
Then I don't have anything recorded in any app until May 2026 when a station with a different ID appeared on the new Swisscharge.
On the Google Street View images from June 2021 we can see a KEBA station in the outdoor parking spaces. There are no lines painted and no signs, but based on the layout it's probably visitor spaces for number 3.
We can also see an underground parking entrance.
