ETSI "Best Presentation Award" für Arbeiten zu interoperablen Ladeschnittstellen

Auf der jährlich stattfindenden ETSI-Konferenz "User Conference on Advanced Automated Testing" erhielt Sven Gröning vom Lehrstuhl für Kommunikationsnetze den aus den Bewertungen aller Teilnehmer bestimmten "Best Presentation Award". Damit werden die am Lehrstuhl seit Jahren durchgeführten Arbeiten zu automatisierten Testprozessen für das Internet of Things, hier speziell für die Ladeschnittstelle in der Elektromobilität, ausgezeichnet (Vortragstitel "S. Gröning, J. Schmutzler, C. Wietfeld, Conformance Testing of Electric Vehicle Charging Communication based on TTCN-3 von S. Gröning, J. Schmutzler, C. Wietfeld). Die Konferenz fand in diesem Jahr am Fraunhofer-Institut FOKUS in Berlin statt.

Abstract - Electric Vehicles (EVs) are a key component for green transportation and future smart grids. At the same time, they define a new, scalable but heterogeneous global market. Hence, interoperability of charging communication is a core enabler for user acceptance and economics of scale. However, its complexity increases by the number of use cases, e.g. for association, authentication and accounting used for Plug and Charge (PnC), demand management or bidirectional power flow. Thus, a considerable amount of testing is required in order to enable interoperability between independent implementations. EV charging communication brings together cross-domain vendors from the automotive-, utility- and communication domain. However, only a standardized approach based on a publicly available and formally defined testing language like TTCN-3 holds true for the required testing scope of the charging communication interface and a systematic approach for corresponding automated test procedures. The presentation gives an overview of requirement-based conformance testing of the Combined Charging System (CCS) using TTCN-3 and describes furthermore lessons learned using TTCN-3 as a formal test case description in a multi-domain standardization process and how automated testing based on TTCN-3 can improve interoperability of electric vehicle charging communication.
