Visited today without charging.
As expected, the new charging spots are installed on the back of the existing chargers.
The contrast between the old and new charger is very impressive. You really get the impression the original site was designed by people who had never touched an electric car, and the upgrade has now been done by people who know what they are doing. Each group of 2 new spots is as wide as 3 old spots. The Hyperchargers are also installed at ground level, with a flat surface all around, a necessity for accessibility. There aren't any spots designed specifically for wheelchair though.
The new chargers are equipped with contactless readers that seem to work. The screen shows a reservation amount of 40CHF. The original chargers have not been retrofitted with contactless readers.
Charger number 4 has been indicated out of service in the app for a month now. On location it's been wrapped in a "coming soon" blanket.
For access you still need to always start by entering the row with the "old" chargers, there's an EV sign there. Then at the end of the row you can come back in the opposite direction in the next row.
