The use of fossil fuel is more which deplete the availability of fuel, So Electrical vehicle is the best option. Electrical vehicle needs the battery for its operation and this battery is charged through electric grid supply. As it imparts the additional load on the grid, which may cause loss in synchronisms of power lines. So it is necessary to develop counter system for balancing the frequency variation. Depending on frequency response the electrical vehicle is charged which takes the account of peak load and off peak load condition. So that the performance of smart grid can be improved and transportation load of vehicle will be minimize to some extend. This paper introduces the strategies in charging structure for minimization of frequency imbalance to make the charging of vehicle at off peak hours and less stressed environment on the grid.
