An electric car is an alternative fuel car that uses electric motors and motor controllers instead of an internal combustion engine (ICE). Currently, in most cases, electrical power is derived from battery packs carried on board the vehicle. Other energy storage methods that may come into use in the future include the use of ultra capacitors, or storage of energy in a spinning flywheel.

The term electric vehicle is often used, implying, in context, an electric road vehicle, though in its broader sense it covers all vehicles with electrical propulsion including trains and trams.

Vehicles that make use of both electric motors and other types of engine are known as hybrid electric vehicles and are not considered pure electric vehicles (EVs) because they operate in a charge-sustaining mode.

Hybrid vehicles with batteries that can be charged externally from an external source are called plug-in hybrid electric vehicles (PHEV), and become pure battery electric vehicles (BEVs) during their charge-depleting mode. Other types of electric vehicles besides cars include light trucks and neighborhood electric vehicles.

In the US as of July, 2006, there were between 60,000 and 76,000 low-speed, battery powered vehicles in use, up from about 56,000 in 2004, according to Electric Drive Transportation Association estimates. There are now over 100,000 neighborhood electric vehicles (NEVs) on US streets.

The REVA is currently commercialized in India, in the UK (since 2003), and in several other European countries (including Cyprus and Greece, Belgium, Germany, Spain, Norway, and Malta). In most countries the REVA is classified as an electric quadricycle, while in the US it is allowed only as an NEV with reduced top speed. More REVAs have been produced than any other currently selling electric car.
