IEA-4E EDNA Workshop on Efficient Electric Vehicle Supply Equipment - EVSE

The way to achieving climate goals goes hand in hand with the adoption of electric mobility. This strategy is already visible as the market of electric vehicles grows in various world regions, according to data from the latest IEA Global Electric Vehicle Outlook from 2017. New implementation of electric vehicle supply equipment (EVSE) is a pre-requisite to support the e-vehicle growth.
The energy performance of the EVSE was the topic discussed in this one day workshop with national and international experts, as part of the ongoing scoping study on "Energy Efficiency of EVSE" initiated by the Electronic Devices and Networks Annex EDNA (IEA- 4E EDNA, 2017: https://edna.iea-4e.org/tasks/evse) of the Technology Collaboration Programme Energy Efficient End-Use Equipment (IEA - 4E).
The state of the art and complexity of testing EVSE for its own energy consumption and efficiency were presented with examples of available technologies for conductive charging, currently investigated by the Austrian Institute of Technology and the European Interoperability Centre for Electric Vehicles and Smart Grids at the Joint Research Centre JRC.
Testing is one of the pillars for developing energy efficiency strategies and policy approaches for EVSE. Learning from e-mobility projects and pilot regions is also needed to understand the roles, interests and capabilities of key players in the supply chain such as EV producers, EVSE producers, e-mobility platforms and grid operators. Technical differences (slow vs. fast charging), environmental conditions (too low or high ambient temperatures), and user patterns for charging can have a significant impact, not only on the energy performance of EVSE as such, but also on the regional electricity grid. Taking the life cycle assessment perspective to consider the energy supply for the charging process shows how the different energy mixes in various IEA countries have an impact on overall greenhouse gas emissions of e-mobility.
The experts discussed aspects of the interaction and use of EVSE by consumers and how these influence the type of location and the business models for e-vehicle charging. The prospects and challenges of inductive charging were also discussed and compared with the current EVSE conductive technologies, in terms of trade-offs concerning product design, use, performance and safety.
This workshop was organized by the ECODESIGN company GmbH and the Austrian Ministry of Transport, Innovation and Technology BMVIT. The slides of the workshop are now available.
The overall energy performance of EVSE encompasses both the charging efficiency as well as the own energy consumption of the infrastructure itself. This is the topic of this workshop with national and international experts, which aims at exploring the current knowledge on energy performance and testing, as basis for energy efficiency strategies and policy approaches for EVSE.
This workshop is part of the activities of the ongoing scoping study on "Energy Efficiency of EVSE" initiated by the Electronic Devices and Networks Annex (EDNA) of the Technology Collaboration Programme Energy Efficient End-Use Equipment (IEA – 4E) under Austrian leadership, and with the coordination of the ECODESIGN company GmbH.
