Locate direct current fast charging systems for electric vehicles at high volume interchanges on major transportation corridors at sites amenable to 5 to 25 minute-long visits.

The U.S. Department of Energy's evaluation of the 2011 EV Project.


Background (Show)

Lesson Learned

The following should be considered in DCFC site selections:
  • DCFC sites should be located along major transportation corridors
  • Approximately half of the DCFC sites along a transportation corridor should be located at very high volume interchanges, with the remaining at slightly lower-volume interchanges
  • Characteristics of the host site should be amenable to activities lasting between 5 and 25 minutes, which is the typical duration for DCFC sessions (suggestions include coffee shops and convenience stores)
  • When choosing the spacing of DCFC sites along transportation corridors, planners should keep in mind that current DCFC technology provides up to 80 miles of driving range in about 30 minutes of charging
There is a greater likelihood that a DCFC will be highly utilized if its location exhibits all of the following location-based characteristics:
  • Within a half mile of a major commuter route
  • On or near the campus of a company with a highly compensated workforce, where it can function as both a workplace DCFC and be publicly accessible
  • It is in a welcoming and conspicuous location (i.e., not too closely associated with the host)
