Abstract:

This paper proposes an innovative charge scheduling method that could significantly improve electric vehicle (EV) users' charging experience with the nowadays battery technology. Specifically, the proposed method considers the characteristics of the batteries to be charged and the constraints of the external power grid; thus, a plan can be devised for efficiently allocating the power of the charging station to the EVs through cyber-physical system. This method prioritizes jobs based on marginal utility to maximize user satisfaction with limited power resources. The power allocation in our method is managed globally and constrained by specific rules to avoid waste or overload in the power grid. Lastly, we simulate several power scheduling methods in charging stations, which validates that the user satisfaction under our method is higher than that of other traditional methods.
