Abstract

The invention discloses a one-to-many wireless charging method and system, and the system comprises a transmitting end which can generate a wireless induction device; at least two receiving ends which are used for receiving the wireless induction device transmitted by the transmitting end. Each receiving end transmits an obtained load feature signal to the transmitting end in a mode of coupling transmission. The transmitting end transmits the wireless induction power with the corresponding power value according to the sum of the load feature signals transmitted by each receiving end. The system achieves the transmission of load feature signal through the load feature signal coupling between the receiving ends and the transmitting end, so as to guarantee the one-to-many wireless charging power transmission, simplify a wireless charging structure, save the cost, and reduce the fault rate.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging method and system. Background technique [0002] Wireless power supply technology (Contactless Power Supply, CPS), also known as inductive coupled power transmission technology (Inductive Coupled Power Transmission, ICPT), contactless power supply refers to the transmission line and the load without electrical connection and physical contact, even between them In the case of relative motion, complete the transmission of electric energy. The theoretical basis of the contactless power supply technology is the principle of electromagnetic induction, using modern electric energy conversion technology, magnetic field coupling technology, modern control theory and microelectronic control technology to realize the transmission of energy from stationary equipment to movable equipment. [0003] In the current technological development, most of them a...
