The invention discloses a dynamic resonant magnetic coupling wireless charging system for an electric vehicle, relates to a wireless charging technology for the electric vehicle, and aims to solve the problems that the charging efficiency is reduced and the power supply quality is reduced due to lateral deviation between an energy transmitting end and an energy receiving end during dynamic charging of the existing electric vehicle. A transmitting magnetic core is a U-shaped magnetic core formed by two end columns and a bottom column, two groups of series-wound coils of each transmitting coil are respectively wound on the two end columns at the opening end of the U-shaped magnetic core, and the distance between the two groups of series-wound coils is adjusted by changing the length of the bottom column; a group of series-wound coils of a receiving coil are wound on a middle magnetic column of an H-shaped magnetic core; N transmitting coils are arranged above a road; the receiving coil is arranged below a chassis; the receiving coil and the transmitting coils carry out energy transmission in a magnetic field coupling mode. The energy transmitted by the transmitting coils is supplied by a power grid power supply, and the energy received by the receiving coil charges an energy storage device. The beneficial effect is that the charging efficiency is high.
