Developing NEC Requirements for Electric Vehicle (EV) Charging Infrastructure
Gary Eldridge, ChargePoint Inc Kenneth Boyce, UL

While some may know that the National Electrical Code (NEC) addresses EV charging infrastructure, the subject remains obscure to most. To shed light on this evolving domain, we will review the history and principles behind NEC Article 625, "Electric Vehicle Charging System." We'll describe the architecture and components of modern EV charging system; the various types of services available (low-power "L1", medium-power "L2", high-power "L3" or "DC Fast Charging", Wireless Power Transfer); the variety of installation sites (public places, dedicated facilities, single and multi-family residential); and associated safety issues and how they are addressed. We'll present the relationship between UL standards and provisions in the NEC.
