Cologne City Hotel at the Roman Tower
On 22 July of this year, the Cologne City Hotel at the Roman Tower put into public operation two 22-kW wallboxes from the manufacturer ebee smart technologies GmbH. People are paying for public charging either with charging cards from the green electricity supplier Naturstrom and many other providers or spontaneously without a card via QR code and an internet connection. ebee charging points with their solid metal housing are ideal for public charging. They are optionally available in the basic model as wallboxes, charging points or as street lamp chargers.
The Cologne hotel operator sees their use as more than just a potentially higher number of overnight stays. "The two charging points are the perfect addition to our car park facilities, which we want to offer to hotel guests as well as external e-mobilists who are looking for a conveniently located green charging point in the centre of Cologne", explains Andreas Wörner, tenant of the hotel that belongs to the Kolping Society of Germany.
The model used at the city hotel is the first version of the ebee wallbox that complies with German calibration law. Since 1 April 2019 when the calibration law was enacted, German law has required the end consumer to be able to trace back previous charging and billing operations at public charging points. The ebee charging points are enabled for this by the Bender CC612 charge controller in combination with the certified "eHZ Mobility" meter from EMH. A cross-vendor transparency software developed by ebee and other members of the so-called SAFE initiative provides the backend communication of these components. Since spring 2019, ebee charging points allow energy to be invoiced in kWh via the backend in accordance with German calibration law.
