This location was listed on Chargemap already a long time ago.
According to that data, the charge used to be free and part of the EVite network. There was an ABB Terra 53 unit with the 43kW AC plug and another double AC charger, though the AC charger is not clearly visible in any of the pictures on Chargemap. The oldest comment if from September 2015 and complained about the lack of marking. A comment from November 2016 however says the marking is good. In October 2021 someone reported the charger limited to about 30kW and another in November 2021 says limited to 22kW.
There are no comments after that but there's a picture of a sign saying that from November 26, 2022 the stations would be for employees only and that early 2023 the chargers would become paid.
Recently, a bunch of chargers are visible on opendata for this area. The markers in front of the building are networked through plugnroll, and might be the original charger now networked. But it doesn't show any tethered T2 or 43kW AC in the data.
To the south of the building there are a bunch of stations networked through eCarUp, I thought those might belong to ABB but since the operator name is "Georg Fischer AG" I guess I better import them into a different marker.
I'll need to visit to confirm all this data and what kind of access is given to those stations.
