Abstract

The goal persists to have a million electric vehicles placed in the german market until 2020. Since July 2012, the Federal Ministry of Economics and Technology (BMWi) therefore funds the project "eNterop", whose goal is to ensure an interoperable communication between electric vehicles and charge spots. Only by doing so, a broad acceptance of electromobility can be attained.

In the course of the project, automatable test suites shall be realized in software and hardware that help to ensure interoperability between such systems. On the other hand, a reference platform shall be defined and be publicly disclosed to help especially small and medium enterprises (SMEs) in accessing the market.

The project with a lifespan of 2 years and a volume of approximately 4.6 million euros is funded at 50 percent by BMWi and the participating industry partners. International standardization for ISO/IEC 15118 vehicle-to-grid (V2G) communication interface is the key factor for the interoperability of electric vehicles and future charging infrastructures, as well as for the integration of electromobility in the energy-economic value chain.

 

Project background

Project background

In the context of the energy turnaround, electromobility takes a central key position:

From an energy-economic standpoint, electrical vehicles as controllable loads and decentralized energy storages can contribute to stabilizing power grids. Therefore, they play an important role when it comes to effective usage of grids, but also in the context of sustainable private transport.

A precondition for that is the required broad acceptance of electromobility and thus an intelligent and seamless infrastructure integration. This can only be attained economically, the the interoperability of all vehicles produced and deployed world-wide with the infrastructure can be ensured. Interoperability also plays a central role when it comes to user acceptance.

 

Project aims

Project aims

Already in 2010, first drafts geared towards the international standardization of ISO/IEC 15118 Vehicle-to-Grid (V2G) Communication Interface have been adoped with the supported of the companies within the eNterop consortium. Now, in the pre-production phase, it is essential to stimulate the establishment and broad deployment of the standards in the market. Therefore, the 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 expensible 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).
