E-mobility: free refueling at the SEEHUB | a3BAU

Whether the latest funding measures as part of the e-mobility offensive or large alliances in the automotive group: e-cars are on the advance as an essential component of climate-friendly mobility. The vehicles, however, are only as clean as the charged electricity, and a high proportion of renewable energies is therefore essential. The fluctuating availability of green energy poses new challenges for the supply network.



“With our work, we are advancing energy research in line with the Austrian climate and energy strategy. We support the development of an intelligent charging infrastructure that is not a closed system, but rather interacts with the vehicle, with local energy production facilities, the grid and finally with the energy markets. We are looking for charging strategies that are environmentally friendly, customer-oriented and at the same time useful for the network, ”says ASCR Managing Director Robert Grüneis, explaining the research focus. Launched in 2013 jointly by Siemens Austria, Wien Energie, Wiener Netze, Vienna Business Agency and Seestädter Entwicklungsgesellschaft Wien 3420 AG, Aspern Smart City Research (ASCR) does research with real data from the urban development area aspern Seestadt on solutions for the future of energy in urban areas. The specific research goal is to optimize energy generation, its distribution, storage and, last but not least, consumption in such a way that sustainable ecological and economic benefits arise for the city and residents.

SEEHUB: Refuel free of charge and support energy research

The immediate “Smart Charging” research location is the new multifunctional multi-storey car park “SEEHUB” of the List Group and BOE Gebäudemanagement GmbH in aspern Seaside town. In addition to soccer fields, there is also a 12 kWp photovoltaic system on the roof of the parking garage. In conjunction with a battery storage system and a dynamic grid connection, this innovative AC and DC charging infrastructure on parking level 1 supplies the “E-Car Operation Center” charging management system developed by Siemens and, in the final expansion stage, optimizes it in a cloud-based manner – and in conjunction with the local microgrid controller of the Building – the individual charging processes.



To get your e-vehicle free of charge[1] To be able to “refuel” or start the charging process as part of the ASCR research project, electric vehicle drivers only need an app (available for iOS and Android). “If a customer wants to drive off again at a certain point in time, the Siemens charging management will in future determine the optimal charging strategy for the time available. Not only are the vehicle type, current charging status and current network parameters taken into account, but weather forecasts for the energy production of the PV system, for example, are also included, ”says ASCR Managing Director Georg Pammer.

“With our solutions, we can buffer electrical energy and make it available for different charging cycles,” says Gerd Pollhammer, Head of Siemens Smart Infrastructure CEE. “Buffer solutions are very important in order to level out peaks in energy consumption and to ensure reference services – especially if you consider the energy consumption of a district as an overall system. There is a special opportunity here to research with real data, to test sustainable and innovative products from the energy sector and to develop them further. “

Usage behavior at the mobility hub

Four Wien Energie charging stations are also integrated into the project or part of the “E-Car Operation Center”. The aim of the research project is to learn more about intelligent charging strategies, load management and usage behavior. “The garage mobility hub is a very important research environment for electromobility; the majority of charging processes take place here in large cities. That is why we want to take a closer look at the usage behavior in Seestadt, ”says Michael Strebl, Wien Energie Managing Director. “In the future, our systems should be network-friendly, but also customer-oriented. This means that we want to use the available green electricity as intelligently as possible, distribute it and prevent network overloads. And: Offering the customer a car that is ready to start exactly when he needs it. “

Intelligent, stable network

The “grid controller” developed by Wiener Netze is also a central component of the infrastructure. It monitors the state of the supply network. “Smart Charging is an important and, from a network point of view, absolutely necessary step if we are moving in the direction of e-mobility,” emphasizes Wiener Netze Managing Director Thomas Maderbacher. “Our supply network is one of the safest in Europe. In order for it to stay that way in the future, research projects like this one are important, “says Maderbacher and continues:” For the expected increase in electric vehicles in the future, a moderate network expansion is necessary in certain areas. In any case, however, suitable control means are required to protect the network from overload. In addition to the use of intelligent load management systems, incentives for consumers through tiered tariffs, control options by the network operator are also necessary if required. “

With forward-looking planning, investment and research, Wiener Netze is already ensuring that the power supply in Vienna and the surrounding area is secure and ready for the energy transition in the future. Wiener Netze invest 300 million euros in this every year.

About the ASCR

The research company Aspern Smart City Research GmbH & Co KG (ASCR) was founded by Siemens AG Austria (44.1%), Wien Energie GmbH (29.95%), Wiener Netze GmbH (20%) and the City of Vienna (Business Agency Vienna 4th , 66%; Wien 3420 Holding GmbH, 1.29%). The basic aim of the ASCR is to develop solutions for the future of energy in urban areas and to make our energy system more efficient and more climate-friendly. This concrete application research should benefit the City of Vienna and its residents. A cooperation model of this magnitude is unique to date. Over 100 people from different scientific fields are directly involved in this research project. In 2019 the second project phase “ASCR 2023” started. A total of 17 “use cases” are the focus of research activities. The spectrum ranges from further intelligent networking of buildings, networks and markets, through new approaches to building heating and cooling, to the possible use of e-cars as future energy storage. www.ascr.at

About the SEEHUB

A meeting place for work, research and sport: perfectly integrated into the urban infrastructure of Seestadt, the SEEHUB was realized as a modern, multifunctional, sustainable garage hybrid building that meets today’s diverse urban requirements to the highest degree. A project of the List Group based in Vienna, which has been successfully active for many decades as a private builder, owner and operator in the areas of garages, real estate, retail and the hotel and catering industry. www.list-group.at
