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.
