The invention discloses a maximum load collection power optimization method for a dynamic wireless charging system, which comprises the following steps of: establishing an equivalent circuit corresponding to a plurality of transmitting coils and a single receiving coil of the dynamic wireless charging system, and collecting a relational expression between the maximum total feed-in system power andthe current on each transmitting coil and a relational expression between the load collection power and the current on each transmitting coil; optimizing the current on each transmitting coil by using a Lagrange multiplier method by taking the maximum load obtaining power as a target; and converting the optimized current on each transmitting coil into each optimized feed voltage through a Kirchhoff circuit law, controlling an actual voltage source of the dynamic wireless charging system to feed according to each optimized feed voltage, and obtaining the maximum load obtaining power of the dynamic wireless charging system. When the maximum total feed-in system power of the multi-transmitting single-receiving system is determined, the maximum load is obtained by optimizing the current on each transmitting coil to obtain the power, and clear guidance is provided for a sectional type dynamic wireless charging system.
