Visited on Monday without charging.
2 charging spots with large reserved spaces in the north parking.
It's 2CHF/hour at first, then 1CHF/h from the 4th hour, then 10CHF max for first day and 12CHF for more days.
There used to be a different model of charger in the same spot, the one that looks like a stretched tube and has small doors to open on either side to access the plug. I don't know the brand. There are pictures of the old charger on Chargemap.
