WP1 Analysis of the situation and needs for validating the interoperability of the different systems

The objective of WP1 is to analyse the actual and future situation in the scope of EV systems and their interaction with the electrical power grid. The analysis will help to define interoperability needs that allow EV deployment according to potential business models. Some challenges which contribute to the optimization of energy use within smart grids will be identified and the needs for new testing procedures will be indicated. The specific objectives are the following:


  • Analysis of actual and expected future potential in EV mobility
  • Study and definition of the reference networks and models to be used for the testing
  • Specification of needs for interoperability between EVs and electrical power system
  • Roadmap for the new services and facilities to be implemented within COTEVOS

WP2 Integration and alignment of testing methods with standards (and standardization needs)

Great efforts are being performed, both at European and international level, to harmonizing standards to achieve interoperability in the field of electro-mobility (which, under the hypothesis of controlled or smart charging, is also strongly related to the smart grid). This is however a very complicated task, not only due to the very rapid evolution of the technology, but also since many electro-mobility actors and stakeholders come from different technological and “cultural” backgrounds.

In addition to the rather established framework mainly regulating the interaction between EV and EV supply equipment (EVSE), a less defined area concerning the grid involves the definitions and the regulations of the interactions between numerous electro-mobility actors. These are in their turn also strongly dependent on the business models that will take place. In order to facilitate the development of common standards in Europe, the European Commission has requested the European Standards Organizations (ESOs) to develop and adopt European standards in support of European policies and legislation by two mandates related to electro-mobility.

The objective of WP2 “Integration and alignment of testing methods with standards (and standardization needs)” is to incorporate COTEVOS into the relevant on-going and realized agreements dealing with the integration of EVs within the electricity infrastructure. As a result, the selected priorities for new tests and conformance testing methods will be assessed by comparing them with the international standardization scenario. The specific objectives are the following:

  • Analysis and alignment of new tests and conformance of test procedures with existing standards, regulations, standardization activities and standardization needs at European level concerning the interaction between EVs and grid infrastructure
  • Definition of priorities for new tests and conformance testing methods with broad consensus at European level (both inside and outside COTEVOS)
  • Assessment of European priorities for new tests and conformance of testing methods by comparison with the international standardization scenario

WP3 Communications and information management

The objective of WP3 is to analyse, define and develop the reference architecture to assess that EV/EVSE systems can interoperate and be used by the smart grid actors, as defined in M/468 (Standardization for road vehicles and associated infrastructure) and M/490.

As COTEVOS is also heading towards future charging technologies, e.g., vehicle to grid (V2G), controlled charging and additional information about the EV(-simulator) like state of charge (SOC) will be needed, which is not fully accessible by the charging station today. Here the concepts are not fully defined yet and therefore we might need to cover one (or more) of the proposed charging infrastructure concepts. The specific objectives are the following:

  • Identify the protocols used by (smart) grid actors
  • Evaluate current level of interoperability for charging interfaces
  • Define (set of) smart grid environment(s) as charging infrastructure
  • Correlation of input/output parameters for test setups (together with WP 4 and 5)
  • Definition of data transfer infrastructure (data transfer protocols)
  • Interface software development
  • Validation of data exchange

WP4 Development of tests and procedures

The objective of WP4 is to create and propose cost effective conformance test procedures based on ideas, suggestions and findings from WP1-3. These test procedures should be commonly accepted and agreed upon among EV, EV infrastructure manufacturers and power utilities. As a result, WP4 will offer the EV OEM’s and power utilities an adequate set of test procedures to assess the performance of the different systems and implementations.

In the process of creating pan-European interoperability, cost effectiveness will be taken into consideration, as well as quality assurance methods like benchmarking and Round Robin tests. A future outcome could be a pan-European certificate.

COTEVOS will open its plans for new testing procedures to other external laboratories. The contact with the external laboratories will be systematic, and the suitable actions to motivate their participation will be realized.

Apart from the efforts to reach common views on how to obtain this Conformance Body through the different planned Workshops, continuous periodic contacts will be kept with other laboratories. Smart Grid International Research Facilities Network (SIRFN) is to be one of the main focus points through which this collaboration will be spread.

An expected indicator to measure the degree of achievement of this network of laboratories would be the common procedures, ways of coordination and harmonized testing capabilities that would have been carried into effect by the end of the project. Some specific objectives of WP4 are the following:

  • (Smart charging) Testing and implementing procedures and standards for smart charging of EVs in order to facilitate load management in the smart cities grid. An advanced case of this is the V2G in order to facilitate power balancing and peak reduction in the grid
  • (Communications) Test and implementing procedures and standards for bi-directional charging communications
  • (Back end identification and clearing) Conformance test of back end systems to a set of minimum functions including financial settlements, roaming and charging types including smart charging
  • (Wireless charging) A set of preliminary conditions will be proposed to test wireless charging
  • (Standardized scenarios) Defining and describing harmonized and unified test procedures (exemplified by a number of well-defined transactions) reflected by findings and scenarios listed in WP3.3 and possibly recommending a minimum set of implementations for WP5.1 and WP5.2. The scenarios can help define benchmark tests to be developed and performed completely or partially by COTEVOS partners.
  • (Potential test EU labs) Identifying potential test facilities distributed across Europe
  • (Reporting) Reporting test results and providing input to industry and standardization bodies (WP4 and WP 5) as well as providing suggestions to future improvement of standardized test procedures

WP5 New and unified test facilities

WP5 aims to create appropriate capacities for testing within the COTEVOS partnership. A more ambitious result is to generalize the outcomes to be applied in the EU and also at the international level, in order to facilitate the adequate EV deployment and integration into the management of the electricity network. The specific objectives are the following:

  • Setting up a unified infrastructure for conformance testing for interoperability
  • Specifying unified tests for wireless charging and proposing measurement setups for electromagnetic compatibility (EMC) tests
  • Setting up a unified infrastructure for integrated functional testing of EV and EVSE power electric and communication interfaces

WP6 Dissemination and communication

The main objective of this WP is to create and support an international network to guarantee that COTEVOS’s development of interoperability specifications and facilities is realized in the best way according to the on-going efforts for EV deployment and properly integrated in the smart grid. This WP ensures that the newly developed knowledge will be exploited on a broad international scale among industry, key users, local or national authorities, standardization bodies and other relevant stakeholders in Europe and the U.S. The specific objectives are the following:

  • To promote project results to different target groups using the dissemination potential of the project partners
  • To gain feedback on the activities of the project
  • To create strong project image and establish the right dissemination tools (e.g., website)
  • To disseminate the project outcome for the right target audiences
  • To raise awareness and to influence decision-makers

WP7 Management

The overall objective is to carry out a sound overall management and coordination of the project. Particular objectives are the following:

  •  To create the necessary governance structure for an effective project direction and management.
  • To establish the internal communication flow and procedures
  • Performing the financial, legal, administrative and technical coordination
  • Project management to ensure that COTEVOS’ objectives are met
  • Managing knowledge and promoting gender equality in the project
  • Establishing management procedures for quality insurance (Project Quality Plan)
  • Coordination activities with the EC
  • Definition of procedures to capture the metrics, defined as success measures of identified goals (section 1.1.2), including prioritization and limitations
