The invention discloses a dynamic wireless charging system and an optimal path planning algorithm thereof. The dynamic wireless charging system comprises (1) a road circular transmitting coil, (2) magnetic field detection vehicles and detection coils carried by the magnetic field detection vehicles, (3) a magnetic field tracking vehicle group and receiving coils carried by the magnetic field tracking vehicle group, (4) a wireless communication device between the magnetic field tracking vehicles and the magnetic field detection vehicles, and (5) a rectifier and a high-frequency inverter included in the magnetic coupling resonant wireless charging system. According to the electromagnetic field theory, the transmitting coil and the receiving coil transmit energy through a high-frequency magnetic field. And (6) the operation mode of the optimal path planning algorithm is as follows: the magnetic field probe vehicle keeps driving linearly along the center of the road, magnetic field information and position information of points at the position are obtained through a plurality of probe coils of the vehicle head and substituted into a circular current-carrying coil space magnetic field equation to obtain the deviation between the current position and the position of the point with the maximum magnetic induction intensity. The absolute position of the point with the maximum magnetic induction intensity can be obtained by combining the position of the vehicle body, the optimal charging path is obtained after the whole road is traversed and sent to the vehicle group running on the charging path, and the vehicle group can run according to the path to achieve the highest charging efficiency.
