Visited yesterday without charging.
2 parking spots reserved for charging in the P+R area.
The parking spots to the north are free with blue disc, but all the spots to the south including the chargers are paid.
On Chargemap and Google Maps, all pictures are of an older innogy charger, probably all from when the charging was free. The oldest Chargemap comment is from February 2015. The latest is from August 2019 and mentions free charging. The Google Maps pictures [1] [2] [3] were uploaded in July 2021 and March 2022, there doesn't seem to be any mean of payment on the charger still. Unfortunately the pictures are a bit too far to read the text on the side of the charger.
