Abstract

Transition to electric vehicles (EVs) is already under way. EVs have demonstrated to be the most fuel economic and emission free among other propulsion technologies. EVs can have a large impact on greenhouse gases (GHGs) reduction, increase in fuel economy, and higher fuel efficiency. The main idea behind this chapter is to analyse step-by-step energy efficiency, which is one of the key factors for technology acceptance. Penetration of EVs into the vehicle fleet affects load demand as well as electricity markets. Smart charging of EVs can remove a tremendous amount of stress from the continually evolving smart grid. Effect of home charging of EVs on electricity demand has been analyzed. More recently, EVs have been looked at as distributed sources of energy, whereby they could back up the power grid during critical high demand periods. With the help of an on-board battery pack, EVs can act as distributed generators and feedback energy to the grid. However, efficiency of energy conversion could become an issue in this power flow. Hence, in this chapter stage-by-stage efficiency of vehicle-to-grid (V2G) power flow has been evaluated.
