Abstract

The invention discloses a wireless charging system which is provided with a transmitting end and a receiving end. The transmitting end comprises a transmitting end adjustable unit, and the receiving end comprises a receiving end adjustable unit. The receiving end adjustable unit responds to a receiving end adjusting parameter and adjusts an output electrical parameter, and the transmitting terminal adjustable unit responds to a transmitting terminal adjusting parameter and adjusts an output electrical parameter. The transmitting end adjustment parameter is related to a first interaction parameter generated by the receiving end. The transmitting end and the receiving end are respectively provided with the adjustable units, so that the bilateral adjustment is realized. The first interactionparameter associates the adjustment of the two sides, so that the two sides can work cooperatively. Moreover, based on the two-side adjustment, the two sides are adjusted respectively rather than theadjustment work at one side, so that the adjustment timeliness of the transmitting end can be reduced. By the common adjustment, the adjustment precision is higher.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless charging system. Background technique [0002] Wireless charging is a technology that uses high-frequency alternating magnetic fields between the transmitter and the receiver to achieve power transmission. This technology realizes complete electrical isolation between the load and the power supply, and has the advantages of safety, reliability, and flexibility. With the With the gradual popularization of technologies such as automatic parking, automatic driving, and intelligent networked vehicles, wireless charging has been widely valued as an extremely advantageous automatic charging method for electric vehicles. Among the various implementations of wireless charging, magnetically coupled resonant wireless charging is more suitable for charging high-power loads, such as electric vehicles, in terms of transmission efficiency, transmission power, transmission distance a...
