Design and Application of Autonomous Vehicle Static/Dynamic Collaborative Wireless Charging System

为了深入研究自动化、智能化的汽车智慧电能补给方法,探索无线电传输技术(WPT)在无人驾驶电动汽车领域的应用。首先介绍2种无线充电方式的充电原理,然后分别对相应的充电系统进行设计,通过仿真对单接收线圈和多接收线圈进行对比分析,得出双接收线圈对电动汽车动态无线充电具有更好的功率抑制作用,并给出了合适的线圈尺寸和空间分布,结合工程应用提出了电动汽车主动位置检测策略及静/动态2种充电方式相结合的协同无线充电方案,最后介绍无线电能传输技术在智能化无人驾驶电动汽车领域的实际应用。

In order to deeply study the automatic and intelligent method of smart electric power supply,this paper explores the application of wireless power transmission(WPT)in the field of driverless electric vehicles.This paper first introduces the charging principles of the 2 wireless charging modes,and then designs the corresponding charging systems respectively.Combined with the simulation,the comparison and analysis of the single receiving coil and the multi-receiving coil are carried out.It is concluded that the double receiving coil has a better power inhibition effect on the dynamic wireless charging of electric vehicles,and the appropriate coil size and spatial distribution are given.Then combined with the engineering application,this paper puts forward the active position detection strategy of electric vehicles and the collaborative wireless charging scheme combining static and dynamic charging modes.Finally,the practical application of radio energy transmission technology in the field of intelligent driverless electric vehicles is introduced.
