I thought I had already written this comment the other week but apparently not, so I'll try to remember what I had to report.
4 markers have appeared in the M-CHARGE app around November 4.
The location has existed on Chargemap for a while (earliest comment from January 2015). On GoingElectric there's a charging log from December 2013 on a Type2 connector so it must have existed for a long time as a free charging station.
On Chargemap some of the pictures must have been uploaded by error, they seem to be from the Panorama Center. The other pictures match with GoingElectric and show a charging island with 4 evbox chargers around it.
There are no hints on either side to know if they have been 4 chargers from the get-go or if it was upgraded later.
All comments on Chargemap and GoingElectric seem to indicate those chargers were 11kW and not 22kW.
The new chargers are listed at 22kW and currently at 35ct/kWh. I have not seen any picture so far to confirm if they have been installed at the same location as the old free chargers.
