Visited today without charging.
The chargers are immediately at the entrance after the ticket gate. Only the first 2 spots have green parking spots. The other 4 spots are regular parking spaces. Not sure if they plan to paint all of them. The first 2 chargers seem to be older but I'll need to check the historical data to see how far apart the new connectors were added.
It's possible to drive around the floor and come back to the chargers, except for the first 2 spots where you need to reverse a few meters until the gate if you need to wait for someone to leave the spot.
No free parking here, it's 1.5CHF for the first hour during the day, 1CHF for the first hour evening+night, or 50ct for 4 hours on Sunday and holidays.
The foot exit is a staircase that leads directly outside in front of the shops and the train station.
