Launched in September 2013, COTEVOS project (Concepts, capacities and Methods for Testing EV Systems and their Interoperability within the Smart Grids) aims to establish the optimal structure and capacities to test the conformance, interoperability and performance of the systems to be included in the Electric Vehicles (EV) smart charging infrastructure. To ensure the widest possible impact and agreement, COTEVOS also invites external parties to contribute to the definition process of its testing procedures.

COTEVOS supports EV deployment by providing a commonly agreed approach and facilities for devices’ and companies’ interoperability assessment. However, COTEVOS is a project not merely devoted to technology development – it stores up a profound impact on various aspects of EV deployment, addressing cross-national transparency, the interaction between grid infrastructure and vehicles, and the operational reliability. In order to facilitate this electro-mobility adoption and the sustainability of the EV market segment, COTEVOS aims to:
- assess and improve the degree of interoperability of the pan-European charging services
- improve the conformance assessment in agreement with standardization and industrial working groups
- facilitate customer acceptance of EVs by reducing some known adoption barriers: availability of charging infrastructure, safety risk concerns and costs (beyond incentive policies)
- assess new systems and applications for the electricity grid in order to allow grid operators to host a larger penetration of EVs within their management procedures.
Interoperability requirements address such topics as a broad range of charging modalities, grid stability constraints and consumer needs, along with a pan-European market for both new and used EVs and greater flexibility in choosing the Energy Provider. Figure 2 shows the complexity of the topics and the interactions between the involved stakeholders. In order to facilitate the EU-wide rollout of electro-mobility, COTEVOS will employ a common testing approach in the processes of conformity and interoperability assessment. This will ensure the compliance of test results across EU members and the necessity of one-time-only equipment testing.

From a global point of view, COTEVOS aims to bring together the current research effort in electro-mobility and, therefore, maximize its efficiency. Cooperating with non-EU countries through its third parties - NREL, University of Strathclyde, and NTUA-ICCS - COTEVOS is an unprecedented example of an electro-mobility EU project working beyond the scope of its European partners. COTEVOS encourages all interested stakeholders and external laboratories to participate in round robin tests and in the development of new testing procedures.
In the course of its work, COTEVOS defines specific methods, tools and facilities to test, analyze and simulate the impact of EV integration in the power grid . Additionally, simulations will help assess and identify potential issues regarding the feasibility of existing protocols and standards for communication and control.
COTEVOS's real-life testing environments, along with the immature standards testing principles, will ensure that technology providers will be able to demonstrate compatibility and suitability of products and services at different stages of the development process (from prototypes to commercial products) and to optimize their offerings during this process.
In the assessment process, COTEVOS also ensures the innovation component. Such innovative designs will be demonstrated in the EV charging infrastructure, communications, protocols and exchange of information, on-going pilots, laboratory coordination, and the integration of the EV within the Smart Grid management.
COTEVOS also addresses issues of EV deployment from the standpoint of services and business. Thus, the project addresses risk reduction by technology adoption and interoperability across providers and countries. The latter is crucial in complex multiparty relationships, which range from integration issues to settlement criteria, calculation fees and new tax implications. All this will ensure the emergence of new business models around electro-mobility conformance.
As one of its main objectives, COTEVOS will suggest short-, medium- and long-term plans for implementation of the adequate infrastructures for the assessment, validation and certification of electro-mobility systems. By also taking into account the economic aspects elaborated in the Business Models analysis, these plans will support emerging test bed providers and accreditation/certification authorities.
COTEVOS has already released its Report on the needs for interoperability between EVs and electrical power system. Further on, COTEVOS will present several reports dealing with standardization needs, gap analysis of conformance testing, the comparison of European priorities for new tests and the analysis of needs for interlaboratory comparison tests. You can find all COTEVOS publications on the website.
With DER Journal’s support, COTEVOS and DERlab have recently announced the call for papers for the COTEVOS/DERlab Special Issue of DER Journal on Grid Integration of Electric Vehicles. Scientists working with electric vehicles and their grid integration are welcome to submit papers by 15 April, 2015.
