€4.6M eNterop project for PEV-charging point interoperability kicks off

The eNterop project, the goal of which is to to ensure the smooth interoperation of plug-in vehicles (PEVs) and charging points from different manufacturers, recently had its kick-off meeting in Berlin. Funding for the €4.6-million (US$6.2-million) project is split 50/50 between the German Federal Ministry of Economics and Technology (BMWi) and industry parters: Continental, Fraunhofer, TU Dortmund, BMW, VW, Daimler, RWE, and Siemens.

The International standard ISO/IEC 15118 defining communication between vehicle and charging stations was recently established to guarantee this interoperability between vehicle and charging point. For manufacturers of control equipment and charging points, however, the implementation of the standard involves elaborate testing with a wide range of different product types and in all kinds of different use cases.

The eNterop project addresses three main topics:

  • Definition of automatable test procedures to enable a self-contained development of conformant products without forcing manufactures into time-consuming and expensive mutual interoperability tests. At the same time, free market develop can be ensured and fragmentation be effectively prevented.

  • Conceptual design and development of a reference implementation as an open technology platform to mitigate technical hurdles during the implementation of new V2G products and services. This addresses especially the development of internationally marketable products of small and medium enterprises.

  • Support of model regions, funded projects and SME in the deployment of standardized technology, so that—at an early stage—application and implementation experience can be fed back to the eNterop technology platform. In this context, the eNterop consortium will support a close contact with the Normungsinitiative Elektromobilität (DIN, DKE, NAAutomobil).

The project is divided into six work packages:

  1. Use cases, system architecture and test cases;

  2. Technology evaluation accompanying standardization;

  3. Reference implementation and test environment;

  4. Hardware reference platform;

  5. Integration of small and medium enterprises (SME) and model region; and

  6. Standardization and public relations.

At the kick-off meeting, the partners presented their plans and initial results in Berlin. Siemens showed a prototype for charging with direct current that already conforms to the standard as well as a system for inductive, cordless charging for which the standard is still to be implemented.
