How many electric vehicles (EV) and EV charging stations are in the United States?

We publish annual data on the total number of registered light-duty battery electric, plug-in hybrid, and hydrogen fuel cell EVs and their combined percentage share of total registered light-duty vehicles in Table 1.9 of the Monthly Energy Review (MER).

Annual and monthly data on EV charging stations are in Appendix F of the MER, which includes national and state-level data. Appendix F includes microdata and documentation for the data compilation methodology and data sources.

Historical, state-level data on the number of registered light-duty battery electric and plug-in hybrid EVs and their combined percentage share of total light-duty vehicles are in the State Energy Data System (SEDS). In the worksheet labeled MSN, you can find the EV-related data.

Historical annual data for 2002 through 2017 are also available on the number of alternative fuel vehicles (AFV) in inventory for four vehicle fleets; the supply of AFVs includes electric, hydrogen fueled, gasoline-electric hybrid, and diesel-electric hybrid vehicles.

Other sources of EV data include:

We also publish projections for stocks (inventories) and sales by type of EV in the Annual Energy Outlook, Counterfactual Baseline cases:

  • Table 39, Light-Duty Vehicle Stock by Technology Type
  • Table 44, Transportation Fleet Car and Truck Sales by Type and Technology
  • Table 45, Transportation Fleet Car and Truck Stock by Type and Technology
  • Table 49, Freight Transportation Energy Use
