Abstract

In this paper, an interactive charging strategy between Electric Vehicles (EVs) and grid is proposed to minimize the main grid load factor and improve the power quality of the system. This strategy optimizes charging schedule in Electric Vehicles to minimize cost, enhances grid stability, and sets the optimal battery charging rate within the electrical limits of the battery. In this interactive strategy, the paper adopts an interpolated FFT algorithm to measure the power system frequency and fuzzy control technology to realize the battery smart charging. In order to ensure the implement of the coordinated charging control, two-way wireless communication network based on ZigBee and GPRS technology is established. The success of this charging strategy can be an important theoretical meaning and promotional value for EV.
