State-of-health based load sharing strategy in vehicle-to-grid systems

Abstract

A novel control strategy to intelligently regulate load sharing in vehicle-to-grid (V2G) systems is proposed in this paper.It is based on sharing the load demand between the vehicles based on the state-of-health (SoH) of their batteries. The strategy employs an on-board smart device that computes the battery aging, and this device communicates with the smart grid controller when the vehicle is connected to the microgrid. This paper also presents the algorithm for determining the share factor, and the implementation details of the control strategy.
