Cumulative sales of plug-in vehicles through July 2018 show that more than half (53%) are all-electric vehicles, according to figures from the US Department of Energy.
Plug-in hybrid vehicles, which use electricity from the grid as well as gasoline, make up the other 47%.
Together, sales of EVs and PHEVs add to more than 900,000 cumulative vehicles from the first sales in December 2010 to July 2018.
