具有全向抗偏移能力及恒流输出的电动汽车无线充电系统
Wireless charging system for electric vehicles with omnidirectional anti-offset capability and constant current output
摘要
Abstract
Electric vehicle wireless power transfer(EV-WPT)technology holds promising application potential.However,during vehicle parking,misalignment or angular deviation in the coupling mechanism can reduce charging power,efficiency,and may even cause charging failure.To address these issues,this paper presents a novel coupling mechanism with omnidirectional anti-offset capability.Additionally,the design method incorporates stray spacing to increase mutual inductance between energy coils,reduce the self-inductance of the transmitting coil,and minimize the wire required for coil winding.Leveraging the decoupling characteristics of dual D-type and Q-type coils,the receiving coil and the receiving-end compensation coil are magnetically integrated,saving space and reducing the amount of magnetic core material needed.Finally,a simulation model with 1.4 kW output power is developed to verify the system's robust anti-offset capability and stable constant current output.关键词
