Abstract
This white paper covers new research providing the first at-scale estimate of electric vehicle home charging. Previous estimates are either based on surveys that reach conflicting conclusions or are extrapolated from a small, unrepresentative sample of households with dedicated electric vehicle meters. The research team combines billions of hourly electricity meter measurements with address-level electric vehicle registration records from California households. The average electric vehicle increases the overall household load by 2.9 kilowatt-hours per day, less than half the amount assumed by state regulators. The results imply that electric vehicles travel 5,300 miles per year, under half of the US fleet average.
