This location was visible through the search feature of the Swisscharge payment page between 2021-10-29 and 2022-05-11, named "Energy Future Days", but its payment page didn't seem to be accessible according to my archived data. It was also not listed on opendata. The IDs were later re-used for the SOCAR station at the rest stop "Cimes de l'Est".
The name and location match with the event that took place here on October 29 and 30, 2021. I have a difficult time finding information about the outcome of that event, but there are a number of pages announcing it, and I found this flyer that shows Socar Charge being a silver sponsor, making it likely they put a fast charger in the parking lot for the event https://www.bfh.ch/dam/jcr:ba2ed3c3-4dbb-4156-8564-f6cc99674e7f/Flyer_EFD.pdf
There's a video on their YouTube https://www.youtube.com/watch?v=fW5diKzeIcY, Facebook https://www.facebook.com/energiecluster.ch/videos/das-waren-die-ersten-energy-future-daysvielen-dank-allen-f%C3%BCr-ihr-interesse-und-e/588904589031587/ and also included in this article https://www.nau.ch/ort/bern/die-energy-future-days-sind-gestartet-66032817 where we see a glimpse of the outside with test drives, but I don't see any SOCAR Hypercharger either inside or outside.
There is another download from their website https://energie-cluster.ch/co2-neutralergebauedepark/beitraege/zusammenfassung-der-1-energy-future-days/ => https://a.storyblok.com/f/111983/x/26a12838b1/efd_messebuch.pdf where each sponsor gets a presentation. Under SOCAR Charge there's a picture of an HYC_150 with one CCS and one CHAdeMO, but I don't recognize the location. It might have been in Gümligen, but the charger doesn't match the 3-plug configuration seen on Swisscharge. EDIT: the location pictured is Stäfa
