A solar plant in an industrial park provides electricity for electric cars. Charging is free until September in the course of the model project.

Ahrensburg. The most innovative charging station in Northern Germany has been opened in Ahrensburg. The station, which has cost about 300,000 euros, has got a photovoltaic on the roof, which supplies solar energy for cars directly. The electricity will be stored in a 36- kilowatt-accumulator and it is sufficient for charging about four cars a day. Until the end of September is it besides free. If the accumulator is empty, the ecological current from the grid is patched in automatically.

The station, which is accessible round the clock, is a part of the German federal model project HansE in the metropolitan region of Hamburg.

The German Traffic Ministry supports with the scope of the project building 50 well accessible charging points at 25 locations.For the dispensers in Ahrensburg there was a 50- per-cent-grant. The government assigns in total 1.8 million euros to the 3.4 million worth project.

The number of electric vehicles in Stormarn increases to 335

“In Hamburg the charging infrastructure is developed quite well, we want to extend it”, says Ulrike Thiessen, the project coordinator at the office for the metropolitan region of Hamburg. The location in the industrial park of Ahrensburg (directly next to the DIY-store Hagebaumarkt) is above all optimal for fast charging, because it is easily accessible for commuters and it is located near the highways. A scientific research carried out by the Rhenish-Westphalian Technical University (RWTH) Aachen will show, when and how much current is being charged.

For Peter Lindlahr, the manager of the project office in Hamburg (Hamburger Projektleitstelle für Elektromobilität hySolutions GmbH), the station in Ahrensburg is the “approachable future”. To bring electric mobility to the public consciousness, one would have to show the relations and to give the possibility to experience the future-oriented alternatives. For example, the drivers can read on a big screen under the solar roof at the Kornkamp-street, how much energy is being produced, accumulated and charged at the moment.

County commissioner: “New technologies suit Stormarn well”

“We need the charging infrastructure to develop electric cars”, says Lindlahr. The specialist expects that “the knot will burst between 2020 and 2022”. After that it would be possible that 30 per cent of cars on the roads of Germany will be electric cars. In fact, the number of registrations has increased in Stormarn lately, too: within one year from 126 to 335 at the moment. Besides, there are 280 hybrid cars, too. In the metropolitan region of Hamburg, which reaches from Cuxhaven to Fehmarn, 4,500 electric vehicles have been registered.

The operator of the both dispensers in the northern industrial park – one of 22 kW for normal charging and one of 50 kW for fast charging – is the company E.on-Tochter HanseWerk AG. “For a solar charging station we need more space than for a traditional refilling station and the  southern orientation”, says Anna Katharina Günther, the project manager for the electric mobility at HanseWerk. The site of the company Schleswig-Holstein Netz AG meets the criteria optimally.

The county commissioner Henning Görtz says the same. “New technologies suit Stormarn well”, he says. Electric mobility is an important component to solve traffic and environmental problems in such agglomerations as round Hamburg. For the mayor of Ahrensburg Michael Sarach it is a good decision to choose the largest town in the district with its 34,000 inhabitants. “It is important not only to discuss the future problems but also to practise them”, he says. The solar charging station is “an important start signal”.

Operating via a chip card or a smart phone application

Operating is simple for beginners, too. One can start the process via a chip card or a smart phone application or an SMS. The settlement takes place later – when the model project and the free phase are finished – through the local electricity supplier. At a normal home socket electric vehicles are charged for 8 to 14 hours. With the wall box, a special charging appliance, it is safer and takes one to four hours less.

The government supports purchasing electric cars with bonuses and tax exemptions, too. By 2020 there should be all over in Germany 28,000 points for normal charging and 7,000 points for fast charging.
