This location was first visible on opendata on 2023-08-12.
The hospital website says this new building was inaugurated on September 18, 2023 https://www.insel.ch/de/neues-anna-seiler-haus
The hospital website refuses to describe any other parking than the Insel parking, but on their arrival page there's a map and on that map there is a covered parking symbol above the Anna-Seiler-Haus building, which is presumably where these chargers are found https://www.insel.ch/de/patienten-und-besucher/ihr-aufenthalt/anreise
On Chargemap there are pictures of the chargers. Charging spot 17 on the left is wider and has a handicap symbol together with EV symbol. Then we don't see all the numbers but from the pictures we can guess it's continuous with green parking spots 17, 16, 15, 14, 13, 12.
No idea of the parking modalities.
Chargemap doesn't have any comment but there are lots of check-ins.
