The Geography of EV Charging

Understanding how regional climates impact charging and driving behavior

In May 2020, FleetCarma released a groundbreaking data-driven study called EV Growing Pains. This was one of the largest studies of EV charging load ever conducted and included an analysis of data from over 3,900 electric vehicles from across North America. This report will utilize the same data set and further examine the real-world data collected in order to showcase the role temperature and seasonal climate plays in influencing charging and driving behavior.

The original data set, which contained a full year’s worth of information (from 1 January through 31 December 2019), has been broken down to reflect the summer and winter months in North America. The vehicles have also been sorted by geographic location into a group representing the North and the South. It includes 40 EV makes and models, as well as home and away charging from various EV charging stations.

Why is temperature important for those managing EV charging load?

“What utilities need to be aware of is that temperature- related impacts to range fundamentally change the charging and driving behavior of the EV owner.”
