Embodiment Construction

[0038] In the following, the system of the present invention will be further specifically described through the embodiments and in conjunction with the accompanying drawings.

[0039] figure 1 Shown is a schematic structural diagram of the dynamic wireless power supply system of the present invention, wherein the power supply module (1) is used to provide input power for the power supply system. In this embodiment, the preset input voltage of the power supply module (1) is 380V directly supplied by the grid. The input voltage of the power module (1) can be adjusted according to actual needs. The rectification and filtering module (2) further includes a rectification sub-module and a filtering sub-module. The rectification sub-module is used to rectify the alternating current output by the power module (1) into direct current, and the filtering sub-module is used to eliminate high-order harmonics in the output direct current of the rectification sub-module. Thus outputting a c...

Abstract

The invention provides an electric car dynamic wireless power supply system based on a resonance magnetic coupling technology and method. The system comprises a power module, a rectification and filtration module, a power oscillation module, an orientation module, a signal control module, an emission unit switching control module, electromagnetic field emission units and electromagnetic field receiver units; the power module, the rectification and filtration module, the power oscillation module, the emission unit switching control module, the signal control module and the orientation module are sequentially connected, and the emission unit switching control module is connected with the plurality of electromagnetic field emission units, and the electromagnetic field receiver units are arranged on an electric car. By adopting the electric car dynamic wireless power supply system, the electric car can be charged dynamically during a driving process, so that the problems of short cruising distance and huge financial consumption of a static charging station of a conventional electric car can be overcome; moreover, the construction is convenient, the transmission capacity is high, the electromagnetic radiation impact is small, and the requirement of beautifying a city can be met, the market prospect is broad.

Description

technical field [0001] The invention belongs to the technical field of wireless power supply for electric vehicles, and in particular relates to a dynamic wireless power supply system and method for electric vehicles based on resonant magnetic coupling technology. Background technique [0002] Electric vehicle wireless power supply technology can be divided into two types: the first is inductive magnetic coupling wireless power supply technology, which uses the principle of electromagnetic induction to supply energy to electric vehicles through magnetic coupling. The effective transmission distance of energy is short, and electric vehicles need to be parked. Alignment with the charging coil at the proper position enables energy transmission, suitable for applications such as charging stations like traditional gas stations. The second is the resonant magnetic coupling wireless power supply technology, which transmits energy through the resonance of the inductor on the resonat...
