Battery Capacity Varies Widely for Plug-In Vehicles
May 26, 2014
Battery-electric vehicles have capacities ranging from 12 kilowatt-hours (kWh) in the Scion iQ EV to 85 kWh in the Tesla Model S. Plug-in hybrid-electric vehicles typically have smaller battery capacities than battery-electric vehicles because their range is extended with a gasoline engine. All of these plug-in vehicles currently have lithium-ion batteries.
