Embodiment Construction

[0040] In the following, the system of the present invention will be further specifically described through the embodiments and in conjunction with the accompanying drawings.

[0041] 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 enhanced-transmitting-coil-based dynamic wireless power supply system and method of an electric car. The system comprises an electromagnetic field transmitting unit. A transmitting coil contains a plurality of layers of spiral planar coils that are successively arranged from inside to outside in a concentrical mode; and an electromagnetic shielding radiation layer covers the spiral planar coils. A magnetic core is arranged at the center of the spiral planar coil at the innermost layer, wherein the shape of the magnetic core is identical with that of the spiral planar coil. The spiral planar coils at the adjacent layers are formed by winding of insulating leads at an opposite direction. The front ends of all spiral planar coils are connected and the tail ends of all spiral planar coils are connected. According to the invention, dynamic charging can be carried out during the electric car driving process, thereby solving problems of short endurance distance of the traditional electric car and enormous costs of a static charging station can be solved. In addition, the construction becomes convenient; the energy transmission is high; the electromagnetic radiation influence is low; the urban beautification requirement can be met; and the market prospects are 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 enhanced transmitting coils. 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 resonator and the...
