"EVs will break the grid" is a common refrain in the press regarding the imminent surge in EV loads. Utilities, regulators, governments, and even the public are concerned about reliability. But the core issue at stake starts with what real-life EV loads are going to be. In this presentation, we will present actual load shapes (NOT modeled) with vehicles from all over the U.S. to address issues such as: Variability in charging between EV models/brands across days of the week and year. How driving patterns differ based on the model/type, battery size and charging speed. Managed vs. unmanaged charging under various rate and program designs (active and behavioral). Impact of temperature/weather on charging needs, battery drawdown, and driving habits. Charging patterns for various use cases: public charging vs home charging, speed of charge, etc. How load shapes inform distribution system operations, DR targeting, and forecasting.
