National Testival about the ISO/IEC 15118 Vehicle-to-Grid Communication Interface on October 1 and 2, 2014 at the CNI


30.09.2014 – Within the context of the energy revolution, the integration of electric mobility into the Smart Grid takes a key position. So far, electric vehicles, charging infrastructures and the distribution network behind these have been self-developed to a great extent. With this, a special challenge is the insurance of interoperability. In the international standardization process, specifications for the communication between the electric vehicle and the charging station as well as between the charging infrastructure and the distribution network are in development at present. In the course of this, the standard ISO/IEC 15118 specifies the communication protocols for AC and DC charging with Demand Side Management and automized authorization mechanisms between the electric vehicle and the charging infrastructure. In doing so, it provides the basis for the Smart Grid integration of electric vehicles.

Within the scope of the project "eNterop", which is supported by the BMWi, a conformity system is being developed, with the aid of which producers can prove their systems in terms of conformity to the communication standard ISO/IEC 15118 for AC and DC charging independently of each other. This way, the project means a first and significant step in the direction of interoperability of electric vehicles and charging infrastructures.

In the light of this project goal, the CNI hosts a project-overlapping testival in cooperation with the "eNterop" consortium consisting of Siemens AG, BMW AG, Volkswagen AG, Daimler AG, RWE AG, Continental AG, Fraunhofer (IFF & IWES) as well as of TU Dortmund (CNI). The aim of this event is to bring together experts and developers and to conduct conformity tests of first implementations of the ISO/IEC 15118 with them, with the aid of the "eNterop" testing system. At that, the exchange of experiences between the participants and the test of the respective implementations in connection with the "eNterop" ISO/IEC 15118 conformity system are in the focus of the event.


DFG Research Group Extended


21.08.2014 – The demands to energy grids are continually becoming more complex because of the use of renewable sources of energy - and with that also the demands to their management, surveillance and their safety. During the last three years, the interdisciplinary DFG research group 1511 has developed innovative safety and guidance systems for future energy systems. The results of this research were presented to the peer reviewers of the DFG as part of an inspection with the result that the research project has been extended for three more years.

As it has been during the first period, Prof. Wietfeld also leads the two subprojects concerning the hybrid simulation of energy grids and communication networks as well as the research on tolerant and real-time capable information and communication networks during the second period of the research group. In the scope of another subproject, he will be in charge of the investigation of new communication solutions for the peripheral agent-based coordination of power flow and voltage control.


CNI with Vehicle-to-Grid Demonstrator at W3C Workshop on "Web of Things" in Berlin


17.07.2014 – At the "W3C Workshop on Web of Things - Enablers and Services for an open Web of Devices", which took place on June 25 and 26, 2014 in Berlin, the CNI presented its research concerning ISO/IEC 15118 standardization for the Vehicle-to-Grid (V2G) Communication Interface. The workshop addressed future research by the W3C (World Wide Web Consortium) for the Web of Things. Assuming that there is more and more networking in the Internet of Things, current issues of how the value creation process of underlying data in the Web of Things can be designed technologically. At that, the integration of electric vehicles into smart grids is a concrete case of application, in which W3C web technologies from the area of Web of Things come into effect.

The CNI is part of the development of the V2G Communication Interface as part of the ISO/IEC 15118 Joint Working Group since years, supported the specification process based on web technologies and leads the Working Group concerned with the development of conformance test standards. For demonstration purposes, a prototype which has been developed by the CNI as part of the eNterop project on the basis of these web technologies has been presented at the W3C Workshop. This prototype demonstrates the communication interface between electric vehicle and charging infrastructure on the basis of ISO/IEC 15118-2 and -3.

Successful Completion of Björn Dusza's Doctoral Studies in the Collaborative Research Center 876


28.02.2014 – Due to strongly increasing data traffic in mobile communications, the influence of the intensive use of mobile services on the battery life of terminal devices comes to the fore for users, application developers and network operators. Based on the new Context-Aware Power Consumption Model (CoPoMo) developed by Björn Dusza, quantitative analyses of the correlation between network resource allocation and battery lifetime can be enabled. An extension of the model for investigating LTE-advanced systems shows that the approaches, upon which CoPoMo is based, are also applicable for future generations of mobile communications. The validation of the presented analytical model was conducted with the aid of realistically modeled simulations and experiments with specific laboratory set-ups. CoPoMo is a substantial outcome of the sub-project A4 of Dortmund's Collaborative Research Center 876.
