Abstract

Electric vehicle dynamic wireless power charging technology is to lay the transmitting coil below the ground. When the electric vehicle with receiving coil is running on this road, the power grid is continuously transmitted to the driving motor of electric vehicle through transmitting and receiving coil, thus realizing the dynamic wireless charging of electric vehicle. In recent years, the dynamic wireless charging technology of electric vehicles has attracted more and more attention of research institutes because of its long endurance mileage, small carrying capacity of on-board batteries and flexible charging methods. In this paper, direct field-circuit coupling multi-physical field simulation is carried out to study the influence of parameters on the dynamic coupling process of the dynamic wireless charging system of electric vehicle. Through simulation analysis, the effect of different parameter changes on the system is effectively reflected. And the real working characteristics of the system are estimated.

电动汽车动态无线充电的场路耦合分析

电动汽车动态无线充电技术是将发射线圈置于地下。当带接收线圈的电动汽车在这条道路上行驶时，电网通过发射和接收线圈不断地传输到电动汽车的驱动电机上，从而实现电动汽车的动态无线充电。近年来，电动汽车动态无线充电技术因其续航里程长、车载电池承载能力小、充电方式灵活等优点，受到了越来越多科研院所的关注。本文通过直接场路耦合多物理场仿真，研究了参数对电动汽车动态无线充电系统动态耦合过程的影响。通过仿真分析，有效地反映了不同参数变化对系统的影响。并对系统的实际工作特性进行了估计。
