The invention belongs to the electric vehicle wireless charging technology, in particular relates to a parallel segmented guide rail type electric automobile dynamic wireless charging system. The system comprises at least three guide rails, switches and high-frequency inverters which are respectively connected with each guide rail, rectifying circuits and a power grid which are sequentially connected with the high-frequency inverters, controllers which are respectively connected with the switches and the high-frequency inverters, and a comparison circuit, an amplifying circuit, a filter circuit and a magnetic sensor array which are sequentially connected with the controller, a plurality of transmitting coils are uniformly arranged in each guide rail; each guide rail and the plurality of transmitting coils are arranged on the ground in parallel; and the magnetic sensor array comprises magnetic sensors which are correspondingly arranged in the transmitting coils on the ground. The systemcan realize dynamic wireless charging of electric vehicles and parallel dynamic wireless charging of a plurality of electric vehicles, solve the problem that the charging efficiency is reduced due totransverse deviation of the transmitting coil and the receiving coil in the running process of the electric vehicles, and improve the dynamic wireless charging efficiency of the electric vehicles.

    本发明涉及电动汽车无线充电技术,具体涉及一种并列分段导轨式电动汽车动态无线充电系统,包括至少3列导轨,分别与每列导轨相连接的开关和高频逆变器,与高频逆变器依次连接的整流电路和电网,分别与各开关和各高频逆变器连接的控制器,依次与控制器连接的比较电路、放大电路、滤波电路和磁性传感器阵列;每列导轨内均匀设置有若干发射线圈,每列导轨及若干发射线圈并列安装于地面上;磁性传感器阵列包括对应安装于地面上各发射线圈中的磁性传感器。该系统实现了电动汽车动态无线充电和多辆电动汽车并排动态无线充电,解决了电动汽车行驶过程中发射线圈和接收线圈发生横向偏移导致充电效率降低的问题,提高了电动汽车动态无线充电效率。
