Visited on May 21 without charging.
There are no directions to the charger, and it could be extremely challenging to find if something blocks your view.
The charger is in the parking extension near Auto SPA. You need to follow the Auto SPA signs, then turn left just before the Auto SPA entrance. This area is physically separated from the main parking by the dual exit lanes. At least there's very little risk of ICE-ing until the parking gets extremely full.
There's a sign describing the 148kWp solar installation on top of the building. Too bad it can only power one charger 🙄
Parking is paid, ticket gates, and presumably closed with the store, though I didn't find any official closing hour for the parking.
