The invention relates to an electric vehicle wireless charging technology, in particular to a segmented coil type electric vehicle dynamic wireless charging system and method. The charging system comprises an energy transmitting part and an energy receiving part, wherein the energy transmitting part comprises a direct current bus, a primary side excitation source and a plurality of dynamic wireless charging units; the primary side excitation source comprises an inverter power supply, a primary side controller and a primary side series compensation network. Each dynamic wireless charging unit comprises a plurality of charging modules, a program control fling-cut switch and an electric energy parameter detection unit; and each charging block comprises a first transmitting coil block and a second transmitting coil block. According to the charging system, on the basis of the same material, the transmitting coil can achieve higher power output, and meanwhile, better economical efficiency isachieved. The magnetic flux above the transmitting coil can be maximized, and high-efficiency transmission is realized. The influence of electromagnetic radiation is avoided, and the breakdown of a single transmitting coil does not cause the breakdown of the overall charging system.

    本发明涉及电动汽车无线充电技术,具体涉及一种分段线圈式电动汽车动态无线充电系统及方法,该充电系统包括能量发射部分和能量接收部分;能量发射部分包括直流母线、原边激励源和多个动态无线充电单元;原边激励源包括分别逆变电源、原边控制器和原边串联补偿网络;各动态无线充电单元均包括多个充电组块、程控投切开关和电能参数检测单元;每个充电组块均包括第一发射线圈组块和第二发射线圈组块。该充电系统在相同材料的基础上,发射线圈能够实现更高功率输出,同时具有更好的经济性。能够使发射线圈上方的磁通达到最大,实现高效率传输。避免了电磁辐射的影响,而且单个发射线圈故障不会导致总体充电系统崩溃。
