Summary Information

Since the introduction of publicly accessible direct current fast charging (DCFC) systems during the EV Project in 2011, the U.S. Department of Energy and others have conducted surveys on deployment and use of DCFC equipment. The EV project deployed over 100 DCFC that used the CHAdeMO charging standard, which was included on all participating Nissan Leaf vehicles, adopted by Japanese automakers. The EV project installed DCFC in eight states in both metropolitan areas and along transportation corridors in rural areas.

System Costs

DCFC stations may charge users by the amount of electricity consumed, number of sessions, amount of time spent plugged in, or a combination thereof. Some operators offer memberships that provide discounts to users at the point of charging.
  • Per kWh of electricity consumed, rates vary from $0.15 to $0.69.
  • Per charging session, rates vary from $7.40 to $9.99. Those who subscribe or pay for a membership to a specific operator may receive a discounted rate per session, one operator provides a $3.00 discount to subscribers and another provides unlimited charging for $19.99 per month.
  • Per minute, rates vary from $0.15 to $0.18 per minute.
  • Other operators combine the models. One operator, EVgo, offers a $4.95 per session rate plus $0.10 to $0.20 per minute rate with a $14.95 monthly subscription.

Adjusting all of the pricing models to cost per kWh, most DCFC customers average between $0.00 and $0.74 per kWh.
