Research on V2G High-Performance Control Strategy of Electric Vehicle Charger

As one of the most important components of electric vehicle, electric vehicle charger ensures the energy conversion between power grid and EV battery. Therefore, the study of its control strategy and charging efficiency has important guiding significance for the development of electric vehicles in the future. Based on this, this paper first analyzes the circuit topology of electric vehicle charging system, and then focuses on the control strategy of different operating modes in the system. In G2V (Grid-to-Vehicle) and V2G (Vehicle-to-grid) modes, A new predictive direct power control strategy based on three-phase PWM rectifier is proposed, which improves the traditional control strategy, simplifies the control strategy of G2V/V2G mode, and improves the charge-discharge efficiency and integration. Finally, the effectiveness and accuracy of the proposed control strategy are verified by simulation and experimental analysis of Simulink software simulation platform and prototype experiment platform.
