Extreme temperatures can affect electric vehicle range, but the extreme heat of the South is nothing to offset the extreme cold in other parts of the U.S., according to new findings.
Vaisala, a Finnish instrumented measurement firm, analyzed the effect of weather and road conditions on EV range across the Lower 48 states, looking at how these factors affected range at different times of the year. That analysis involved not only temperature by month, but also winds, rolling resistance from snow, air density, and solar radiation, among other factors.
States at lower latitudes, with hotter average temperatures, showed better results. The top five states for EV range, based on a median and across all local climatic conditions were Arizona, Florida, Texas, Georgia, and Louisiana. The bottom five were the more northern—and frigid—Maine, Vermont, New Hampshire, North Dakota, and Minnesota.
