Discovered while driving by on August 24.
There are 2 charging stations among the public paid parking spaces next to the Mehrzweckhalle.
The chargers have no branding except for the SolarEdge sticker. I plugged in and the charge started automatically. The stations must be 16A/11kW, because I was charging at 3kW with my single-phase charger.
This must be a recent addition, because I can't see this location on any community map. The paint doesn't seem particularly fresh, but the chargers seem to be new. If the "total kWh" value shown on the screen is since installation, then very few people must have used them because they show 44 and 28 respectively.
On the June 2022 Google Street View images, there are no chargers. The parking spaces are still regular white.
I wrote to the municipality to ask for details but have not received a reply yet.
Since the parking is paid around the clock (1CHF/h), I think free electricity would be quite reasonable. With a single phase charger it ends up costing about the same as at Coop. With 3-phase it's a bargain at less than 10ct/kWh.
