An electric vehicle (EV) is powered by an electric motor using electricity stored in a battery. These vehicles produce no tailpipe emissions, use less oil and gas, have fewer moving parts, and are quieter than traditional engines. They also have superior energy conversion efficiency and generate less waste heat, reducing the need for engine cooling systems that are large, complex, and maintenance-prone.
EVs are becoming increasingly popular, and a variety of factors are helping fuel this growth. For example, improved battery technology has made it possible for these cars to travel significantly farther between charges than older lead-acid batteries. In addition, advances in regenerative braking have decreased the need for conventional brakes and allow these cars to reuse some of their energy. Finally, the relatively low purchase price of an EV can make it more affordable for many buyers.
Battery electric vehicles (BEVs) use a rechargeable battery to power their electric motor and can typically drive up to 500 miles before needing to be recharged. Examples of BEVs include the Tesla Model 3 and the Chevy Bolt. Plug-in hybrid electric vehicles (PHEVs) combine a battery with a conventional gasoline or diesel engine to provide more driving range than BEVs. These vehicles may need to be charged more often and can take up to 6 hours to fully charge.
As EVs gain in popularity, many people are concerned about their impact on natural resources. However, several measures can help mitigate this concern, including managed charging, which allows drivers to access cheaper electric rates during off-peak times and enables utilities to manage demand on the power grid using technologies like vehicle-to-grid.
