Modeling and safety analysis of ev charging system
In view of the deterioration of the performance of ev wireless charging technology due to electromagnetic compatibility,the model and safety analysis of the ev charging system based on the principle of induction coupling energy transmission system.First-ly,the transmission characteristics of electric vehicles are calculated through the two-port network model;then the coil structure of the coupling mechanism of the charging system is selected and led;finally,the electromagnetic compatibility of the shielding coil and the electromagnetic environment on the human body.The simulation results show that the simulation analysis of the two-segment port network can be realized by using the cooperative simulation function of CST software,obtaining the wireless charging system with out-put power of 6kW and output efficiency of more than 90％.The system verification found that the proposed method can improve the system performance and the safety of human radiation,so that the system can reach the radiation standard limit.
