The wireless charging dynamic control equipment comprises a power transmitting circuit group, a multiplexer, a micro controller, an information detection circuit, a power supply module and a coil array; the power supply module is connected with the information detection circuit; the information detection circuit is connected with the microcontroller and the power transmitting circuit group; the microcontroller is connected with the multiplexer and the power transmittingcircuit group; and one side of the multiplexer is connected with each sub circuit in the power transmitting circuit group while the other side is connected with each coil in the coil array. By virtueof the wireless charging dynamic control equipment, reasonable allocation of system resource can be realized, the system transmission efficiency can be improved, and product experience, safety and reliability can be improved; and by changing the coil array structure and parameters, the coupling coefficient deviation between the coil array and a load coil can be lowered.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and in particular relates to a wireless charging dynamic control device supporting multiple loads and a control method thereof. Background technique [0002] With the popularization of smart phones and wearable devices, the way of charging with power lines and data lines can no longer meet the explosive growth of smart devices. Wireless charging has developed rapidly in recent years, and wireless charging systems are more The ability to charge load devices has become the most urgent demand at present. For a wireless charging system, the transmission efficiency is the first indicator to measure the performance of the wireless charging system. It is necessary to effectively judge the power transmission requirements of the load device, reasonably allocate the power transmitted by the transmitting side to the load device, and build an efficient and reusable system architecture. It is the k...
