BEV (sometimes BOEV) is the abbreviation for "Battery Electric Vehicle". A BEV is a type of electric vehicle (EV) that uses chemical energy stored in rechargeable battery packs. BEVs use electric motors and motor controllers instead of internal combustion engines for propulsion.

BEVs are also named battery-only electric vehicles or all-electric vehicles. A BEV derives all its power from its battery packs and thus has no internal combustion engine, fuel cell, or fuel tank. BEVs include bicycles, scooters, skateboards, rail cars, watercraft, forklifts, buses, trucks and cars. The best-selling BEV in history is the Nissan Leaf, with sales of 200,000 units worldwide by early December 2015, followed by the Tesla Model S, with global sales of 100,000 units also by early December 2015.
