The invention discloses an electric vehicle wireless charging power dynamic balance control system, which is characterized by comprising a plurality of energy transmitting coils arranged corresponding to charging parking spaces, each energy transmitting coil is correspondingly provided with an inverter, the front ends of the plurality of inverters are connected in a DC-DC dynamic matrix module, and the front ends of the plurality of inverters are connected in the DC-DC dynamic matrix module. The three-phase power supply supplies power to the DC-DC dynamic matrix module after passing through the multi-path PFC converter, the three-phase power supply also supplies power to the power transmission control module after passing through the rectification module, and the power transmission control module obtains charging demand information of each charging parking space through the intelligent charging platform. And the output state of each DC-DC converter in the DC-DC dynamic matrix module is controlled according to the charging demand information, so that wireless charging power dynamic balance control is realized. The method has the advantages that the output power of each charging parking space can be dynamically adjusted according to the number of the currently accessed users, so that the charging speed is increased as much as possible on the premise that the standard charging time is met, and quick charging of each user is ensured.
