| Summary: | Aim of the paper is to demonstrate evolution of Electric Vehicles (EV) and their infl uence on the Smart Grid (SG). Starting from USA defi nition of the SG considering the fi fth- and sixth- properties of the SG: It accommodates all generation and storage options and it enables new products, services and markets. We can determine EV role in the SG operation. Contemporary we can distinguish following types of the EV: HEVS – hybrid electric vehicles with motor and use batteries with no using electricity from external source, Pure EVs – running on electric motor powered by batteries that are recharged by plugging in the vehicle, Plug-in PHEVs – can be charged with electricity like engine power EVs and run under engine like HEVs. The most interesting for electric power there are Pure EVs and PHEVs that are consumers and also kind of electricity storage devices (very important in SG). These types may be charged “in home”, using special station with diff erent time of charging; there is also considered charging during the time waiting for change of lights on road nodes (junctions). It is important to mention that EV development infl uence not only on SG, social- and climate- environment but also on development of new branch of industries producing equipment necessary for EV operation.
