There has been a big upgrade here. 75 Swisscharge IDs have appeared for this location. The existing Evpass IDs are still there and appear to still receive activity.
The website of the parking has been updated. On April 15 (last copy in the Wayback Machine) it read:
E-Tankstellen
3.OG Nr. 3_134, 3_136, 3_138 und 3_139 (4 E-Tankstellen)
Befinden sich am Ende des Parkgeschosses, kurz vor der Ausfahrt aus dem Parkgeschoss (blauer Signalisation folgen)
Now it reads
E-Tankstellen
69x E-Ladepunkte im 3 Obergeschoss:
3.OG Nr. 3_001 – 3_045
3.OG Nr. 3_002 – 3_046
3.OG Nr. 3_047 – 3_093
6x E-Ladepunkte im 4 Obergeschoss:
4.OG Nr. 4_001 – 4_010
It seems like they are not counting the evpass chargers anymore in the new version. I assume they are not going to stay if they now offer their own chargers. The old text said 4 chargers, but the evpass app still lists 5 chargers to this day. Evpass says there's one for PP132 which is not listed in the old text on the website. The PP numbers for evpass and Swisscharge don't overlap, so they probably were not forced to remove the old chargers to make space for the new ones.
I wonder why in the new text they say 1-45 and 2-46. That's probably because one row has all the odd numbers and another row all the even numbers?
Another part of the description says "Familienparkplätze (XXL-PP): 4.OG ganzer Stock (95 Parkplätze)", so that would mean the charging stations on floor 4 are XXL as well. There's no other tariff mentioned on the website, so XXL spots might cost the same as regular spots?
I can't find any picture of the new Swisscharge chargers at this time. I doubt all 75 chargers are on parking spaces reserved for charging. I hope those on level 4 are since there are fewer than on level 3.
There's also a page explaining you can rent a dedicated spot with charging station. I don't know if they dedicate one of the 75 stations to you or if those are additional stations installed on demand.
