At the Hannover Trade Fair (April 7-11, 2014, booth C10, exhibit hall 13), ESK researchers will be demonstrating how the charging station serves as an interoperable node between the e-vehicle and the network control center using the ISO/IEC 15118 and IEC 61850 standards. Having already implemented both communication interfaces, ESK engineers can now illustrate how the concept works in practice.
Fraunhofer ESK developed an intelligent charging infrastructure for e-vehicles based on the ISO/IEC 15118 and IEC 61850 standards.

With its solution, the institute helps charging station and e-vehicle manufacturers and grid operators to implement the communication standards and test their products for standards compliance.
Value-added services based on IEC 15118
Whether vehicle authentication, automatic time-delayed charging or dynamic billing models – digital communication before, during and after charging is essential not only for the charging process. It also allows charging station operators to offer customers a wide range of value-added and convenience services. This also requires complex, EU-wide communication technologies. This requirement, which is also being demanded by the EU, led to the creation of the ISO/IEC 15118 standard.
"Our experience has shown that charging station manufacturers are still shying away from the standard because the implementation is too complex," explains Dr. Erik Oswald from Fraunhofer ESK in Munich. "For this reason, we developed a reference installation that significantly streamlines the implementation."
As part of the SmartV2G (smart vehicle to grid interface) research project sponsored by the EU, ESK researchers carried out a thorough technology analysis and subsequently developed an enhancement of the ISO/IEC 15118 standard to effect communication between the charging station and the e-vehicle. They then tested the interaction of the individual components using the HomePlug Green PHY transmission technology together with IPv6. Interoperability tests will also be carried out over the course of the project.
Uniform grid communication based on IEC 61850
Energy providers and grid operators are forced to communicate with a wide range of elements in the network. These range from various energy sources such as biogas or solar systems, to different types of end users such as private homes, industry parks and e-vehicle charging stations. To date, this communication has been based on proprietary protocols.
With the enhancement and implementation of the IEC 61850 standard that stemmed from the energy industry, Fraunhofer ESK is introducing trade fair visitors to an additional solution that supports the conversion of the power grid to renewable sources. The enhanced IEC 61850 standard not only enables the simple and flexible integration of charging stations and e-vehicles into the smart grid. Energy providers and grid operators now have one standard for communicating with all elements in the network, thus significantly streamlining their energy management systems. By combining these international standards, the charging station is transformed into an interoperable node that transfers the intelligence of the smart grid to the e-vehicle charging process.
The smart grid communication experts at Fraunhofer ESK are available to share their extensive know-how with charging station and e-vehicle manufacturers. This includes technical advice on charging station enhancements, hardware selection and support during integration of the interfaces and standards into the existing software, and testing the charging stations for standards compliance. The charging infrastructure, which is being demonstrated at the joint Fraunhofer Energy Alliance exhibit booth in the form of software and hardware, acts like a remote node to test the implementation of the communication standards and the products.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
