Define "battery electric vehicle" (BEV).

A battery electric vehicle (BEV) is specifically defined as a vehicle that operates entirely on electricity stored in its battery pack. Unlike vehicles that combine different forms of energy, such as gasoline and electricity, a BEV does not use any fossil fuels for propulsion. This type of vehicle relies solely on electric motors for movement and is recharged through external electric power sources.

The BEV's design and functioning are pivotal to the transition towards sustainable transportation. It produces zero tailpipe emissions, contributing to a decrease in pollution and promoting cleaner air quality. The technology behind BEVs, which includes advancements in battery efficiency and electric drivetrains, supports the growing automotive industry's move towards electrification.

In contrast, options that include hybrid technologies or minimal electric components do not meet the stringent criteria for a BEV since they incorporate other energy sources or functionalities.
