    FOTW# 1161: A Tool is Available for Estimating Charging Loads from Plug-In Electric Vehicles

    Originally posted by the Department of Energy Office of Energy Efficiency and Renewable Energy | Original Article

    The National Renewable Energy Laboratory has recently upgraded their Electric Vehicle Infrastructure Projection (EVI-Pro) Lite tool to inform industry stakeholders about the electricity needed to charge plug-in vehicles. Within the tool, users can customize to their own specifications for:

    • Location (city and state)
    • Number of plug-in vehicles
    • Average daily miles per vehicle
    • Average ambient temperature
    • All-electric vehicle share
    • Vehicle type
    • Share of workplace/home charging
    • Charging levels
    • Charging time of day.

    Real-world travel data from consumers are used to model future requirements for residential, workplace, and public charging under different scenarios. The model results for the electric load profile for a fleet of 1,000 plug-in vehicles in Indianapolis, IN, are shown below as an example. EVI-Pro Lite is also useful for estimating the number of electric vehicle chargers needed in an area to sustain a certain number of plug-in vehicles.

    Example of EVI-Pro Lite Results

    Note: EVI-Pro Lite has been developed through a collaboration between the National Renewable Energy Laboratory and the California Energy Commission, with additional support from the U.S. Department of Energy's Vehicle Technologies Office. Load profile analysis capabilities in EVI-Pro Lite have been developed through a collaborative effort between the National Renewable Energy Laboratory, Lawrence Berkeley National Laboratory, and Schatz Energy Research Center at Humboldt State University.
