Battery electric vehicles (BEVs) captured a record amount of total plug-in vehicle battery capacity sold in 2019, with 17.4 gigawatt-hours of total capacity. Plug-in hybrid electric vehicles (PHEVs) accounted for a smaller portion of total vehicle battery capacity due to their lower sales volumes, and because they require smaller battery packs than BEVs.

PHEV sales decreased by 32% from 2018 to 2019, about the same as the decrease in PHEV battery capacity. Tesla’s Model 3 sales accounted for most of the increase in total BEV capacity between 2017 and 2018.
