How do battery electric cars work

Battery electric vehicles (BEVs) use electricity stored in battery packs to power motors, producing no tailpipe emissions and offering lower fueling costs than internal combustion engines. While their total pollution depends on the electricity source, they remain cleaner than gasoline cars even on coal-heavy grids. BEVs feature energy-saving technologies like regenerative braking and typically offer ranges between 70 and 265 miles.

• Battery electric vehicles (BEVs) produce no tailpipe pollution, although the total environmental impact depends on the electricity source used for charging. In the United States, BEVs remain less polluting than gasoline vehicles even when using a grid dominated by coal, and they are virtually emission-free when powered by solar or wind energy.
• BEVs offer economic and efficiency advantages over conventional vehicles, including potential annual gasoline savings of over $1,000. They increase efficiency through 'idle-off' technology, regenerative braking, and the inherent efficiency of electric motors compared to internal combustion engines.
• Most BEVs have a driving range between 70 and 100 miles, though some can reach 265 miles on a single charge. They differ from plug-in hybrids, which combine electric motors with combustion engines, and fuel cell electric vehicles, which generate electricity from hydrogen gas.
