I visited on May 20 but could not find the Eponet chargers.
The Lidl parking is a fully open area under the store, you are not supposed to park there outside business hours, but there doesn't seem to be any gate. I drove around and there are no chargers there.
There are also no chargers in the private parking spaces in front of the Lidl building.
I didn't see any underground parking entrance.
The last area I can think of but didn't check is the road behind building 19, where it's also all private, but I don't think there are even 10 parking spaces there.
Real mystery where the chargers could be...
The chargers are only listed on IchTankeStrom and there are no sessions reported yet. Maybe they will come to the Lidl parking, but have not been actually installed yet.
