Seen yesterday from the train.
The chargers are in the outside parking controlled with a parking meter.
The EV sign is more comprehensive than other evpass signs, clearly stating "Reserviert für Elektrofahrzeuge während des Ladevorgangs", with electric car and bike icons, and parking meter icons.
The chargers are equipped with ad-hoc QR codes, though I was not able to test them from that distance 😇
I was able to confirm the ParkingPay number 3780:5, but unfortunately it doesn't seem like we can consult the prices on ParkingPay website or EasyPark app. In EasyPark, I see it's 0CHF no matter how long I select right now, so it must be free at night. I'll need to test during the day to see if there's a free period.
