Visited on Sunday without charging.
All chargers referenced on eCarUp are freely accessible in various parking lots of the dealership. All charging spots were left free over the weekend.
On location there is zero instructions or explanation, you wouldn't know the chargers are networked. In the eCarUp app it says "Für KIA Import Kunden". The chargers don't seem open to roaming.
The only useful indicator is that they printed the charger numbers on them (AC1, AC2, DC1, DC2, ...) which seem to match with the names in the eCarUp app.
All AC chargers both to the east and to the south of the Kia building have attached cables. The 2 slow DC chargers have a CHAdeMO connector that is not listed on eCarUp.
The AC chargers to the south in front of the building have 3 green parking spots marked "Besucher" and the 3 other spots are marked "Reserviert" and don't have the EV logo.
The fast charger is an ABB Terra 184HC with 300A nominal / 400A boost cables.
