There's something unusual here, on the Swisscharge picture we can see that the sign is not the usual for Basel-Stadt area, this one has a parking meter symbol for 8h-19h instead of blue disc.
However this seems out of place, because all the pictures I can find show the streets around are still blue zone, so there would be no reason to install a parking meter just for the charging spaces. We don't see any meter on the Swisscharge pictures.
The Google Street View images are too old.
The Swisstopo satellite pictures show the charging spaces, and the parking next to it is still blue.
