Seen today, 4 charging stations in the visitor parking lot for Busbetrieb. The parking lot of freely accessible, but there are no usage instructions on the stations.
There are MOVE chargers listed for this location on Swisscharge and Chargemap, but the information seems to be stale. There's nothing in MOVE app at the moment. Swisscharge shows all stations offline. Chargemap shows all stations unknown status with a last synchronization date of November 2022.
These MOVE stations were briefly visible on IchTankeStrom between end 2022 and beginning 2023, named "Primeo Energie - Busdepot BOGG Wangen bei Olten". The coordinates seem to match quite well with the chargers I found, but there's a possibility the networked chargers are inside or behing the depot, which is not visible from the main road.
