Visited yesterday without charging.
We used to see 2 chargers on eCarUp here. The second is no longer visible in the eCarUp app but is still on opendata, stuck in out of service status. It's also visible on the eCarUp web map as a marker but says "error" when clicked. Generating a payment link for that charger still works, but says unavailable, so I suspect it's still there. All the signs of a charger configured to be private.
I saw one charger in front of the building among the visitor spots, that's the one still visible on eCarUp. I saw a second pico behind the gates on the south side of the building, I assume that's the other one that used to be visible. There's a third charger to the north, also behind the gated area.
There are 2 spots with an EV icon among the visitor parking, that's because there used to be 2 free evbox chargers here, as pictured on Chargemap. There are comments as old as April 2017. A comment from April 2020 says the chargers are out of service. The next comment is from February 2023 saying the new pico chargers on eCarUp are operational. On GoingElectric the location was added on 29.11.2016.
