Visited on May 19 without charging.
There's a big EV sign on the totem outside and at the entrance gate. This is a public paid parking with limited opening hours.
There's a sign saying free parking for restaurant customers. I assume they validate your ticket or give you an exit ticket in the store, because there's nothing in the parking about this.
The chargers are split between levels 2 and 3. One of the chargers is DC and I would have tested it, but it was already occupied.
The 3 spaces on level 2 are painted green with EV sign. On level 3 the spots are not painted, but there's the same EV sign on the wall next to it.
The ramps between the levels are tight.
The only payment machine I found did not accept credit cards, only cash.
I'm not sure when this location opened. Eponet is not on IchTankeStrom. On the Google Street View images from June 2023, the EV signs are already present. On the images from June 2021 they are not there.
You can rent parking spots in this parking https://faehrhof-immobilien.immomigsa.ch/de/o/zu-vermieten-parkplatz-egerkingen-1197278 In that case you can likely use the chargers around the clock.
