What is a battery electric vehicle (BEV)?

How a battery electric vehicle works

A battery electric vehicle stores electrical energy in a battery pack and uses it to power an electric motor. The pack is recharged by plugging the vehicle in to a power source. The U.S. Department of Energy's Alternative Fuels Data Center also calls them all-electric vehicles. It says they produce no direct exhaust or tailpipe emissions. It adds that generating the electricity they use may contribute to air pollution. As of October 2026 it gives typical driving ranges of 150 to 400 miles.

How a BEV differs from a plug-in hybrid

A plug-in hybrid electric vehicle, or PHEV, has both an electric motor fed by a battery and an internal combustion engine. It can be plugged in and driven on electricity alone for a moderate distance. That is about 15 to 60 miles or more in current models, according to the Department of Energy as of October 2026. The engine runs when the battery is mostly depleted. A conventional hybrid also combines an engine and a motor, but its battery is charged through braking rather than from a plug.

The U.S. Environmental Protection Agency puts the difference simply. It says an electric vehicle has a battery in place of a gasoline tank and a motor in place of an engine. A plug-in hybrid, it says, has all four.

Why the label matters in sales figures

The Department of Energy notes that all three types are sometimes loosely called electric vehicles, or EVs. Sales reports group them in different ways, so totals are comparable only when they count the same thing.

• In the European Union, battery-electric cars were 21.7% of new registrations from January through August 2026, according to the carmakers' association ACEA. It put plug-in hybrids at 10% for the same period.
• BYD reports "new energy vehicle" sales that combine both types. Its filing for September 2026 lists 1,629,957 battery electric and 1,448,587 plug-in hybrid passenger vehicles sold in the first nine months of the year.
• Tesla describes its vehicles as fully electric. That means a comparison of Tesla and BYD is like for like only when it uses BYD's battery electric figure.
