Title:
DYNAMIC MULTISTAGE WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/215171
Kind Code:
A1
Abstract:
A dynamic multistage wireless charging system comprising: a transmission end and a receiving end. The transmission end comprises: a wireless charging device, and an induction circuit connected to the wireless charging device. The receiving end comprises: a controller, and an electric energy receiving circuit and a driving device connected to the controller. By means of cooperation between a square coil in the induced circuit and the electric energy receiving circuit, a large lateral displacement is allowed, and a large coupling coefficient is achieved, such that a parameter of a circuit required for charging does not need to be manually re-adjusted, thereby keeping the parameter in an optimal state, and keeping the charging efficiency constant. By means of cooperation between multiple guide rail coils in the transmission end and the square coil, a guide rail supplies power in a segmented manner, such that self-inductance of the guide rail coil is low, and the overall stability of the system is high. By means of parallel connection between groups of electric energy adjustment circuits, a power requirement on a single circuit is greatly reduced.
