Visited on June 8 without charging.
The chargers are in the public parking. Based on the signage, you pay for parking like regular spaces.
However the maximum duration seems to be different than regular spots. Whereas parking is generally max 4h (during paid hours), the charging stations say max 11 hours. I was not able to check whether the parking meter lets you pay for more than 4 hours as it was Sunday and parking was free.
The newer chargers are on the left. The parking spaces are not yet painted, but the vertical signage makes it clear those spots are also reserved for charging.
