A wireless charging receiving device, wireless charging method and equipment for smart cars and electric vehicles. The device includes: at least one set of receiving coils, a compensation network group, a rectification circuit, a switch component and a controller; the compensation network group includes n groups of compensation networks, and the n groups of compensation networks are different in circuit topology and / or device configuration parameters, The input end of each set of compensation network is connected to the output end of the receiving coil, the output end of each set of compensation network is connected to the input end of the rectification circuit, n is an integer greater than 1; the controller is used to control the switch component to connect the n sets of compensation network One or more groups are connected to the receiving coil and the rectifier circuit to realize the selection of different charging modes. In the solution provided by the embodiment of the present application, multiple sets of compensation networks are designed in the wireless charging receiving device, so that it supports a variety of different charging modes, enriches the wireless charging methods, and better meets actual charging needs.
Description
technical field [0001] The embodiments of the present application relate to the field of wireless charging technology (wireless charging technology), and in particular to a wireless charging receiving device, a wireless charging method and equipment. Background technique [0002] Wireless charging technology refers to the technology in which electric energy is transmitted between the charger and the electric device by a magnetic field, and there is no need for a wire connection between the two to realize charging for the electric device. Wireless charging technology is used in power-consuming devices such as mobile phones, smart watches, and electric vehicles. [0003] At present, the wireless charging method is relatively single, which cannot well meet the actual charging needs. Contents of the invention [0004] The embodiment of the present application discloses a wireless charging receiving device, a wireless charging method and equipment, which can be used to solve t...
