Visited on October 26 and charged with contactless, no issue.
When I saw the new chargers appear in the live data, I was wondering whether they added truck chargers like in Kölliken. But even before my visit I found out where the new chargers were, based on this Google Maps contribution from earlier this month where we see they opened up the foundations to add 2 additional chargers to the right of the existing chargers https://maps.app.goo.gl/BQZ5JUksdYafLmff9
That's indeed what I saw on location, they used the space that was already planned out since the construction of the rest stop to expand to 8 charging spots. The foundations were probably already installed and they just dug through the pavement to open them up. depth of the parking spaces clearly shows they are meant to be painted straight like the existing green spots.
The new chargers have the "Socar Express" livery with 400kW written on them, making them the first 400kW Socar chargers for cars, and their second time fully speccing an Alpitronic HYC_400 (the first was the truck charger in Kölliken Nord).
The new chargers don't have numbers of EVSEIDs printed on them yet. While I charged there alone on the leftmost new connector, it shows 3A occupied in the live data, so the order from left to right seems to currently be 2, 1, 3, 4. I wonder if they will re-number the chargers to restore them in driving order. While I did not charge on the older chargers and just checked out the numbers written on them, I can also confirm the white Skoda on my drone pictures showed up 2B occupied in the live data as expected.
