Restrictions on fossil fuels and related environmental pollution issues motivate many organizations and countries to set their focus on electric vehicles (EVs) rather than conventional internal combustion engine vehicles. The EV market and fleet growth create continuously increasing demand for available charging infrastructure. To improve user experience, modern vehicles tend to have increased battery pack voltages that allow for faster charging rates. In the case of dc charging this results in the need for charging converters that can cover wide range of voltage in order to be compatible with both older and forthcoming vehicles. Simultaneously to EV fleet growth and associated increase in electricity demand, challenges related to the power grid stability need to be considered and addressed. Moreover, proliferation of renewable energy technologies increased the attractiveness on dc grid technology and universal ac/dc – supplied solutions are needed to address this trend.

This seminar is devoted to the state of art overview of charging infrastructure for electric vehicle including market and infrastructure, battery technologies, novel power electronic solutions and industrial examples from Estonia and Poland. The agenda of the webinar is as follows:

14:00    Andrei Blinov. Introduction: EV market and infrastructure (10 min)

14:10    Parham Mohseni. State of art overview of battery packs technologies for EV (15)

14:25    Mohammad Mahad Nadeem. Overview of the wide range power electronics chargers for EV (15)

14:40    Oleksandr Husev. Concept of universal battery onboard/opportunity chargers for EV (15)

14:55    Andrei Blinov. Single-stage electric vehicle DC charging concepts (15)

15:10    Juhan Härm (Vool). State of the EU electric vehicle supply equipment market (20 min)

15:30    Oskar Kreft (AREX). Electric vehicle charging infrastructure as a part of the electricity management system (20 min)

15:50    Q&A and discussion
