The invention belongs to the technical field of dynamic wireless charging of electric vehicles, and discloses a stacked dynamic wireless charging system for an electric vehicle and a control method of the stacked dynamic wireless charging system. The system comprises a mobile side subsystem and a power supply side subsystem. The power supply side subsystem comprises a sectional type guide rail and a control assembly, the sectional type guide rail is laid below the road surface, and the control assembly is connected with the sectional type guide rail; the mobile side subsystem comprises a receiving coil, and the receiving coil is arranged at the bottom of the electric vehicle; the sectional type guide rail comprises a plurality of transmitting coil guide rails, the transmitting coil guide rails are arranged in an alternate stacking mode, and the transmitting coil guide rail located on the lower layer is arranged at the switching position of every two adjacent transmitting coil guide rails located on the upper layer. The transmitting coil guide rail comprises a shutdown mode, a standby mode and a power output mode, and the control assembly regulates and controls the working mode of the transmitting coil guide rail according to monitoring information. According to the invention, the problems of power drop and efficiency drop of the dynamic wireless charging system of the electric vehicle at the guide rail switching position can be solved.
