Grid-integrated EV Charging: Current Issues and Prospective Solutions
Thursday, November 17, 2022 09:00 AM – 03:00 PM (MS Teams)
This workshop will present the development and evaluation of fully integrated systems that connect electric vehicles (EVs), charging infrastructure, buildings, smart power grids, renewable energy sources, and behind-the-meter electric energy storage options. Topics covered will include: EV charging infrastructures; power electronic based energy conversion systems; DC fast charging; wireless charging systems; grid interface issues; vehicle-to-grid, vehicle-to-home, and vehicle-to-load systems; battery energy storage and battery management systems. The workshop will also discuss ongoing projects undertaken with industry partners and forthcoming topics of interest to the community, industry and policymakers.
