Visited yesterday without charging.
There are 2 non-networked chargers to the east of the building on spots 26 and 27, labelled "e-tron". A 24kW DC and a Zaptec AC.
The fast chargers are to the south of the main building with 4 bright blue parking spots. It seems to be open and accessible any day and time of the week.
The sign promoting the AMAG network and offering to get a coffee or tee in the showroom while charging must mean this is indented to be used by the public, or at the very least by any owner of an AMAG-brand car.
This location finally gave me some hints as to what happened to the AMAG network which has been down for a month now. This location is the first I see with new charge:ON QR codes. Their website https://chargeon.helion.ch/ seem to be yet another charging payment system. The list of partners being mostly AMAG-related makes sense. It seems to be a rebranded version of the autoSense payment system. They have their own app but you can also choose "AMAG" when connecting in the base autoSense app. I didn't create an account yet, but with my autoSense account I can also see the chargers and they are listed at 1.5CHF start fee + 0.54CHF/kWh, which isn't bad. I don't remember the old Intercharge Direct price, but I remember it was outrageous, something above 80ct/kWh.
The charge:ON QR code on the charger has a "Charge without App" option, which didn't work yesterday, throwing a javascript error on any browser I tried. But I just tried again now and it seems to work (at least it shows prices, it seems to still throw an error after choosing the payment method)! The ad-hoc price is listed at 1.50CHF start fee + 1.02CHF/kWh. Now that's even more outrageous than anything I remember 😱
