Visited on May 19 without charging.
The chargers are in P3, a fact indicated right at the entrance with the live number of parking spaces available. There are no other directions between the entrance and the first pillar in P3, but that's not an issue, you just follow P3.
There are no gates, parking is free. I didn't see any maximum parking time posted. There was a reminder of the center opening time at the bottom of the ramp (not pictured).
The Swisscharge pictures, checked back in August 2024 and again today show all spots equipped with T2 cables, but that's no longer the case. 6 chargers didn't have any cable on my visit. 1 definitely had one. The last charger was in use so I don't know if it was the station cable of the owner's cable.
